Ofrecen estabilidad estructural, una gran capacidad de carga y una f\u00e1cil instalaci\u00f3n. Se utilizan ampliamente en l\u00edneas de transmisi\u00f3n el\u00e9ctrica, estaciones base de comunicaciones, transmisi\u00f3n de radio y televisi\u00f3n, y proyectos de protecci\u00f3n contra rayos. Su estructura b\u00e1sica consta de columnas principales de acero (normalmente perfiles angulares de patas iguales o de patas desiguales), tirantes y travesa\u00f1os transversales y diagonales de perfil angular, unidos mediante pernos o soldadura para formar una estructura espacial en forma de celos\u00eda. La base suele tener una secci\u00f3n transversal cuadrada o triangular, y la estructura general se estrecha hacia arriba, adoptando una forma c\u00f3nica o escalonada para equilibrar la estabilidad y la eficiencia en el uso del material.Las torres de perfil angular pueden dise\u00f1arse de forma flexible en cuanto a altura, dimensiones de la secci\u00f3n transversal y especificaciones del perfil angular, en funci\u00f3n de los requisitos de carga (como la carga del viento, la formaci\u00f3n de hielo y el peso de los equipos) y del escenario de aplicaci\u00f3n.

Presentaci\u00f3n del producto<\/strong><\/p><p>1. Componentes estructurales: Se componen principalmente del cuerpo de la torre, los travesa\u00f1os, los tirantes y los cimientos. El cuerpo de la torre es la estructura principal, construida a partir de m\u00faltiples secciones de perfil angular de acero unidas mediante pernos; los travesa\u00f1os se utilizan para sujetar las l\u00edneas de transmisi\u00f3n; y los tirantes mejoran la estabilidad y la capacidad de carga del cuerpo de la torre.<\/p><p>2. Normas de aplicaci\u00f3n: GB\/T 2694-2010, DL\/T 5442-2012<\/p><p>3. Estructura b\u00e1sica<\/p><p>Cuerpo de la torre: Estructura principal de la torre de perfil angular, construida a partir de m\u00faltiples secciones de perfil angular unidas mediante pernos. Por lo general, la estructura es cuadrada o triangular, lo que le confiere una gran rigidez general y una elevada capacidad de carga.<\/p><p>4. Travesa\u00f1os: Se utilizan para sujetar las l\u00edneas de transmisi\u00f3n, como alambres, cables y fibras \u00f3pticas, garantizando una transmisi\u00f3n estable y segura.<\/p><p>5. P\u00f3rticos diagonales: Mejoran la estabilidad y la capacidad de carga del cuerpo de la torre, lo que permite que la torre de perfiles angulares resista mejor diversas cargas.<\/p><p>6. Cimentaci\u00f3n: En funci\u00f3n de las condiciones geol\u00f3gicas, se pueden utilizar cimentaciones independientes, cimentaciones en banda, cimentaciones con capuch\u00f3n de pilotes y otros m\u00e9todos para fijar la torre de perfil angular al suelo y soportar el peso de la torre y diversas fuerzas externas.<\/p><p>Nivel de protecci\u00f3n: El espesor del recubrimiento galvanizado debe cumplir los requisitos de la norma DL\/T 764.4-2001.<\/p><p><strong>Nivel IV de resistencia al viento<\/strong><\/p><p>1. De acuerdo con la norma GB 50009-2012 \u00abC\u00f3digo de cargas sobre estructuras de edificios\u00bb y la norma GB 50135-2019 \u00abC\u00f3digo de dise\u00f1o de estructuras altas\u00bb, el dise\u00f1o debe basarse en la presi\u00f3n del viento en la base en el lugar de instalaci\u00f3n (por ejemplo, entre 0,3 y 0,8 kPa; en zonas costeras, puede superar los 1,0 kPa). Esto garantiza que la torre no se vuelque ni sufra da\u00f1os estructurales en caso de vientos fuertes (por ejemplo, tifones de fuerza 10 o superior).<\/p><p>2. Resistencia s\u00edsmica<\/p><p>De conformidad con la \u201cNorma GB 50011-2010 sobre dise\u00f1o s\u00edsmico de edificios\u201d, y bas\u00e1ndose en la clasificaci\u00f3n por zonas de intensidad s\u00edsmica (por ejemplo, de 6 a 9 grados), se llevan a cabo la optimizaci\u00f3n de la rigidez estructural y el dise\u00f1o del refuerzo de las uniones para garantizar la integridad de la estructura de la torre bajo cargas s\u00edsmicas.<\/p><p>3. Protecci\u00f3n contra la carga de nieve y hielo<\/p><p>En las regiones fr\u00edas, deben tenerse en cuenta las cargas de nieve (por ejemplo, entre 0,2 y 0,7 kPa) y las cargas de hielo. La separaci\u00f3n entre los travesa\u00f1os y el dise\u00f1o de la inclinaci\u00f3n de las torres se optimizan para evitar sobrecargas provocadas por la acumulaci\u00f3n de nieve y hielo.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div id=\"e-n-tab-content-649863462\" role=\"tabpanel\" aria-labelledby=\"e-n-tab-title-649863462\" data-tab-index=\"2\" style=\"--n-tabs-title-order: 2;\" class=\"elementor-element elementor-element-2e2154e e-con-full e-flex e-con e-child\" data-id=\"2e2154e\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-0f27574 elementor-widget elementor-widget-heading\" data-id=\"0f27574\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Caracter\u00edsticas del producto   <\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f30b232 elementor-widget elementor-widget-text-editor\" data-id=\"f30b232\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p><strong>I. Caracter\u00edsticas principales<\/strong><\/p><p>1. Forma estructural flexible<\/p><p>Las torres de perfil angular se construyen principalmente con perfil angular. Pueden dise\u00f1arse con secciones transversales triangulares o cuadrangulares, en funci\u00f3n de los requisitos de altura y carga (como la resistencia al viento, la resistencia al hielo y la capacidad de carga). La torre tambi\u00e9n puede dividirse en segmentos para facilitar su instalaci\u00f3n en terrenos complejos (como monta\u00f1as y colinas).<\/p><p>2. Rendimiento estable en cuanto a la capacidad de carga<\/p><p>El perfil angular de acero, al tratarse de una estructura de acero, presenta una gran resistencia a la compresi\u00f3n, a la tracci\u00f3n y al cizallamiento. La torre est\u00e1 unida mediante nudos para formar una estructura espacial de vigas en celos\u00eda, que transfiere de manera uniforme las cargas (como el peso propio, el viento, el hielo y la nieve) a los cimientos, lo que garantiza una elevada estabilidad general.<\/p><p>3. Alto aprovechamiento del material<\/p><p>La forma de la secci\u00f3n transversal del perfil angular es adecuada para soportar fuerzas axiales y momentos flectores. Durante el dise\u00f1o se pueden seleccionar diferentes especificaciones de perfil angular en funci\u00f3n de los requisitos de carga de cada ubicaci\u00f3n, lo que reduce el desperdicio de material y hace que sea m\u00e1s ligero que estructuras como las torres de hormig\u00f3n.<\/p><p>4. F\u00e1cil desmontaje<\/p><p>La mayor\u00eda de las torres de perfil angular se ensamblan con pernos en lugar de soldaduras, lo que facilita su transporte, instalaci\u00f3n y mantenimiento. En caso de traslado o renovaci\u00f3n, pueden desmontarse y volver a montarse, lo que reduce los costes de obra adicionales.<\/p><p>5. Caracter\u00edsticas estructurales: dise\u00f1o de celos\u00eda estable y eficiente<\/p><p>Las ventajas mec\u00e1nicas de las unidades triangulares, la flexibilidad del montaje modular y la distribuci\u00f3n econ\u00f3mica de la carga.<\/p><p>6. Caracter\u00edsticas del material: Excelentes propiedades mec\u00e1nicas y gran capacidad de carga.<\/p><p>7. Caracter\u00edsticas de aplicaci\u00f3n: Su elevada resistencia, buena plasticidad y tenacidad, as\u00ed como sus propiedades mec\u00e1nicas uniformes, facilitan la ampliaci\u00f3n de sus funciones en diversos terrenos y entornos.<\/p><p>8. Caracter\u00edsticas t\u00e9cnicas: F\u00e1cil construcci\u00f3n y mantenimiento, peso ligero y f\u00e1cil transporte e instalaci\u00f3n.<\/p><p><strong>II. Principales ventajas<\/strong><\/p><p>1. Capacidad de adaptaci\u00f3n a entornos complejos<\/p><p>Las torres de perfil angular se fabrican principalmente con acero al carbono o acero galvanizado. Tras someterse a un tratamiento anticorrosivo (como el galvanizado y el pintado), presentan una gran resistencia a la intemperie y pueden soportar un uso prolongado en entornos hostiles, como altas temperaturas, alta humedad, zonas costeras (niebla salina) y desiertos, con una vida \u00fatil de m\u00e1s de 30 a\u00f1os.<\/p><p>2. Construcci\u00f3n pr\u00e1ctica y eficiente<\/p><p>Los componentes se prefabrican en f\u00e1bricas con gran precisi\u00f3n. La instalaci\u00f3n in situ no requiere grandes equipos de elevaci\u00f3n (en el caso de torres peque\u00f1as y medianas). El proceso de montaje es sencillo y el plazo de construcci\u00f3n es breve, lo que las hace id\u00f3neas para proyectos en zonas remotas o con espacio limitado.<\/p><p>3. Control de los costes<\/p><p>En comparaci\u00f3n con las torres de tubos de acero y las torres de hormig\u00f3n, los costes de los perfiles angulares de acero son menores, y los costes de transporte e instalaci\u00f3n tambi\u00e9n se reducen. Esto las hace especialmente econ\u00f3micas para torres de altura media a baja (menos de 50 metros).<\/p><p>4. Requiere poco mantenimiento<\/p><p>La estructura abierta, con componentes a la vista, facilita la inspecci\u00f3n para detectar problemas como la corrosi\u00f3n o tornillos sueltos. El mantenimiento requiere la sustituci\u00f3n selectiva de los componentes da\u00f1ados, lo que elimina la necesidad de un desmontaje exhaustivo.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div id=\"e-n-tab-content-649863463\" role=\"tabpanel\" aria-labelledby=\"e-n-tab-title-649863463\" data-tab-index=\"3\" style=\"--n-tabs-title-order: 3;\" class=\"elementor-element elementor-element-764f307 e-con-full e-flex e-con e-child\" data-id=\"764f307\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-9872304 elementor-widget elementor-widget-heading\" data-id=\"9872304\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Estructura del producto<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b1b2cc5 elementor-widget elementor-widget-text-editor\" data-id=\"b1b2cc5\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Explicaci\u00f3n detallada de la estructura de una torre de perfil angular: Una torre de perfil angular es una estructura de acero en celos\u00eda construida con perfiles angulares de patas iguales y de patas desiguales como componentes portantes principales, unidos mediante pernos. Se utiliza ampliamente en l\u00edneas de transmisi\u00f3n de alta y ultraalta tensi\u00f3n, estaciones base de comunicaciones y sistemas de vigilancia meteorol\u00f3gica. Su dise\u00f1o estructural debe equilibrar la estabilidad mec\u00e1nica, la adaptabilidad a la carga y la compatibilidad con el terreno. La torre se puede desmontar en tres m\u00f3dulos: el sistema central de soporte de carga, el sistema de funciones auxiliares y el sistema de conexi\u00f3n y fijaci\u00f3n. La forma estructural, la funci\u00f3n y la l\u00f3gica de dise\u00f1o de los subcomponentes dentro de cada m\u00f3dulo son las siguientes:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-5474a64 e-flex e-con-boxed e-con e-child\" data-id=\"5474a64\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-24a71fc elementor-widget elementor-widget-text-editor\" data-id=\"24a71fc\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p><strong>I. Sistema central de soporte de cargas: la estructura principal para la transferencia de cargas<\/strong><\/p><p>El sistema portante central es el elemento clave que permite a la torre de \u00e1ngulos de acero soportar cargas externas (como la tensi\u00f3n de los conductores, las cargas del viento, las cargas por formaci\u00f3n de hielo y las cargas s\u00edsmicas). Este sistema determina la estabilidad general de la torre y est\u00e1 compuesto principalmente por la cabeza, el cuerpo y las patas de la torre. Estos tres componentes est\u00e1n unidos r\u00edgidamente mediante pernos, formando una v\u00eda de transferencia de carga de arriba abajo (cargas de los conductores y del cable de tierra \u2192 cabeza de la torre \u2192 cuerpo de la torre \u2192 patas de la torre \u2192 cimentaci\u00f3n \u2192 suelo).<\/p><p><strong>1. Cabeza de la torre: zona funcional superior que soporta la carga<\/strong><\/p><p>La cabeza de la torre es la zona clave situada en la parte superior de la torre de perfiles angulares de acero, destinada a la instalaci\u00f3n de conductores, cables de tierra y dispositivos de aislamiento. Su forma estructural debe cumplir los requisitos de dise\u00f1o de la l\u00ednea en cuanto a \u201cn\u00famero de ramificaciones de los conductores, separaci\u00f3n entre fases y distancia de aislamiento\u201d. Entre los tipos m\u00e1s comunes se encuentran la copa de vino, la cabeza de gato, el tallo y el cuerno de carnero. Aunque los distintos tipos de cabezales de torre difieren en la disposici\u00f3n de sus elementos, sus componentes b\u00e1sicos siguen siendo los mismos:<\/p><p>\u2460 Subcomponentes del cabezal de la torre: Soporte del cable de tierra<\/p><p>\u2461 Travesa\u00f1o para conductores<\/p><p>\u2462 Brazo en \u00e1ngulo<\/p><p>\u2463 Material principal de la cabeza de la torre<\/p><p><strong>2. Cuerpo de la torre: el elemento principal para la transmisi\u00f3n de cargas verticales<\/strong><\/p><p>El cuerpo de la torre es la secci\u00f3n intermedia que conecta la cabeza y las patas de la torre, representa el 60%-80% de la altura total de la torre y act\u00faa como el \u201ctronco\u201d de la torre de perfiles angulares de acero. Su dise\u00f1o estructural debe encontrar el equilibrio entre la ligereza y la alta resistencia. Normalmente se utilizan cerchas de celos\u00eda cuadradas o rectangulares, cuyas dimensiones transversales disminuyen de forma escalonada de abajo hacia arriba (cada secci\u00f3n mide entre 3 y 6 metros de altura, con una relaci\u00f3n de reducci\u00f3n de la secci\u00f3n transversal \u226415%). La estructura espec\u00edfica es la siguiente:<\/p><p>\u2460 Elemento de la torre principal<\/p><p>\u2461 Miembros de la web<\/p><p>\u2462 Diafragmas<\/p><p><strong>3. Patas de la torre: la secci\u00f3n de soporte de carga de transici\u00f3n que se une a los cimientos<\/strong><\/p><p>Las patas de la torre constituyen la uni\u00f3n fundamental entre la torre de perfiles angulares y los cimientos. Deben transmitir todas las cargas (verticales, horizontales y momentos flectores) de la torre a los cimientos. Adem\u00e1s de adaptarse a terrenos complejos, como monta\u00f1as, colinas y valles fluviales, el dise\u00f1o estructural se caracteriza por su adaptabilidad al terreno:<\/p><p>\u2460 Pilar de la torre principal<\/p><p>\u2461 Refuerzo diagonal de las patas<\/p><p>\u2462 Secci\u00f3n de conexi\u00f3n con los cimientos<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-316f71b e-flex e-con-boxed e-con e-child\" data-id=\"316f71b\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-415ab2d elementor-widget elementor-widget-text-editor\" data-id=\"415ab2d\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p><strong>II. Sistemas de funciones auxiliares: estructuras que garantizan la seguridad, el funcionamiento y el mantenimiento<\/strong><\/p><p>Aunque los sistemas de funciones auxiliares no soportan directamente la carga principal, son fundamentales para el funcionamiento, la construcci\u00f3n y el mantenimiento seguros de la torre. Entre ellos se incluyen principalmente los siguientes componentes:<\/p><p><strong>1. Sistema de escalada<\/strong><\/p><p>Escalera: Situada a lo largo del lado interior de los elementos principales de la torre, est\u00e1 formada por una viga de escalera (\u00e1ngulos de acero de \u222050\u00d75) y pelda\u00f1os (barros de acero de \u03c616, separados entre s\u00ed 300 mm). La viga de la escalera est\u00e1 atornillada a los elementos principales de la torre. Cada 10 metros hay una plataforma de descanso (un bastidor rectangular compuesto por \u00e1ngulos de acero de \u222063\u00d75 recubiertos con chapas de acero estampadas). Una barandilla de 1,2 m de altura (varillas redondas de acero de \u03c620) rodea la plataforma.<\/p><p>Dispositivo antica\u00eddas: Se ha instalado un riel antica\u00eddas (barros redondos de acero de \u03c632) paralelo a uno de los lados de la escalera y fijado al diafragma transversal de la torre. Los trabajadores de la construcci\u00f3n llevan dispositivos antica\u00eddas que se deslizan a lo largo de los rieles para evitar ca\u00eddas. Las uniones del riel deben estar lisas para evitar que se atasquen.<\/p><p><strong>2. Protecci\u00f3n contra los rayos<\/strong> <strong>Sistema de puesta a tierra<\/strong><\/p><p>Conductor de bajada: Utiliza un perfil angular de acero de \u222050\u00d75 mm o un perfil redondo de acero de \u03c616 mm. Inst\u00e1lelo verticalmente a lo largo del exterior de la estructura principal de la torre, conectando el extremo superior al soporte de puesta a tierra y el extremo inferior a la rejilla de puesta a tierra de los cimientos. Fije el conductor de bajada a la torre con abrazaderas cada 2 metros para evitar el desgaste causado por la vibraci\u00f3n del viento.<\/p><p>Nodo de puesta a tierra de la torre: Suelda una \u201cplaca terminal de puesta a tierra\u201d (chapa de acero de 100 \u00d7 80 \u00d7 10 mm, Q235B) a la estructura principal de la torre. La placa terminal cuenta con cuatro orificios para pernos destinados a la conexi\u00f3n con el electrodo de puesta a tierra horizontal (acero redondo de \u03c612 mm o acero plano de 40 \u00d7 4 mm) de la red de puesta a tierra. La placa terminal debe estar galvanizada por inmersi\u00f3n en caliente para evitar la corrosi\u00f3n.<\/p><p><strong>3. Estructura resistente a la corrosi\u00f3n<\/strong><\/p><p>Protecci\u00f3n contra la corrosi\u00f3n de los materiales: Todos los perfiles angulares, las placas de refuerzo y los pernos est\u00e1n galvanizados por inmersi\u00f3n en caliente (espesor del recubrimiento de zinc \u2265 85 \u03bcm), lo que garantiza una vida \u00fatil en exteriores de m\u00e1s de 30 a\u00f1os. En zonas costeras o expuestas a la niebla salina, se requiere una capa adicional de pintura de fluorocarbono (de 60 a 80 \u03bcm de espesor) para mejorar la resistencia a la corrosi\u00f3n por niebla salina.<\/p><p>Estructura de drenaje: Deben preverse orificios de drenaje (\u03c610 mm) en las placas de refuerzo de la torre para evitar que el agua de lluvia se acumule en los refuerzos y provoque la corrosi\u00f3n de los pernos. El perfil angular de la cord\u00f3n inferior de la cruceta de la cabeza de la torre debe tener una inclinaci\u00f3n (1:100) para evitar que el agua se filtre en las cadenas de aislantes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-5fc33e8 e-flex e-con-boxed e-con e-child\" data-id=\"5fc33e8\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-4652b00 elementor-widget elementor-widget-text-editor\" data-id=\"4652b00\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p><strong>III. Sistema de conexi\u00f3n y fijaci\u00f3n: clave para garantizar la integridad estructural<\/strong><\/p><p>Todos los componentes de la torre de perfiles angulares se montan mediante uniones atornilladas. La fiabilidad del sistema de uni\u00f3n determina directamente la estabilidad general de la torre. Incluye principalmente los siguientes componentes fundamentales:<\/p><p><strong>1. Pernos de uni\u00f3n<\/strong><br \/>Tipo y especificaciones: Utilizar \u201cpernos de cabeza hexagonal gruesa\u201d (GB\/T 1228), fabricados en acero Q235B o Q355B, con un grado de resistencia de 8,8 (pernos de alta resistencia). Las especificaciones de los pernos vienen determinadas por las cargas que soportan los elementos: para los elementos principales de la torre se utilizan pernos M24-M30, y para los elementos del alma, pernos M16-M20. Cada uni\u00f3n debe contar con al menos cuatro pernos (seis como m\u00ednimo en el caso de las uniones sometidas a tracci\u00f3n).<\/p><p>Requisitos de instalaci\u00f3n: Los pernos deben fijarse con una tuerca doble (tras apretar la tuerca superior, afloje la tuerca inferior 1\/4 de vuelta antes de apretarla). Los pernos deben tener al menos dos roscas expuestas. El di\u00e1metro del orificio para el perno debe ser entre 1 y 2 mm mayor que el di\u00e1metro del perno (por ejemplo, un perno M24 con un orificio de \u03c625,5 mm) para evitar tensiones durante la instalaci\u00f3n.<\/p><p><strong>2. Placa de refuerzo<\/strong><br \/>Forma estructural: Utilizar chapas de acero rectangulares o trapezoidales (material Q355B, de 10 a 25 mm de espesor). Se deben prever orificios para pernos seg\u00fan el n\u00famero y el \u00e1ngulo de los elementos de uni\u00f3n. Los bordes de las placas de refuerzo deben estar redondeados (radio \u2265 10 mm) para evitar la concentraci\u00f3n de tensiones. Las placas de refuerzo situadas en los puntos de intersecci\u00f3n de varios elementos (como el cuerpo y la cabeza de la torre) deben ser de tipo reforzado (entre 3 y 5 mm m\u00e1s gruesas que las placas de refuerzo est\u00e1ndar).<br \/>L\u00f3gica de fuerzas: Las placas de refuerzo act\u00faan como \u201cintermediarias\u201d en la transferencia de cargas y deben soportar simult\u00e1neamente las fuerzas de tracci\u00f3n, compresi\u00f3n y cizallamiento de varios elementos. Por lo tanto, sus dimensiones deben determinarse mediante la \u201cverificaci\u00f3n de la resistencia de los nudos\u201d, asegur\u00e1ndose de que la separaci\u00f3n entre los orificios de los pernos y la distancia al borde de la placa cumplan los requisitos para evitar fallos por cizallamiento y extrusi\u00f3n (por ejemplo, la distancia entre el centro del orificio del perno y el borde de la placa debe ser \u2265 1,5 di\u00e1metros del perno).<\/p><p>\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div id=\"e-n-tab-content-649863464\" role=\"tabpanel\" aria-labelledby=\"e-n-tab-title-649863464\" data-tab-index=\"4\" style=\"--n-tabs-title-order: 4;\" class=\"elementor-element elementor-element-265fa39 e-con-full e-flex e-con e-child\" data-id=\"265fa39\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-73d198a elementor-widget elementor-widget-heading\" data-id=\"73d198a\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Especificaciones<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div id=\"e-n-tab-content-649863465\" role=\"tabpanel\" aria-labelledby=\"e-n-tab-title-649863465\" data-tab-index=\"5\" style=\"--n-tabs-title-order: 5;\" class=\"elementor-element elementor-element-53e5531 e-con-full e-flex e-con e-child\" data-id=\"53e5531\" data-element_type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-bd32b31 e-flex e-con-boxed e-con e-child\" data-id=\"bd32b31\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div id=\"e-n-tab-content-649863466\" role=\"tabpanel\" aria-labelledby=\"e-n-tab-title-649863466\" data-tab-index=\"6\" style=\"--n-tabs-title-order: 6;\" class=\"elementor-element elementor-element-a681f0e e-con-full e-flex e-con e-child\" data-id=\"a681f0e\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-11bf213 elementor-widget elementor-widget-heading\" data-id=\"11bf213\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Preguntas frecuentes<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d080af3 elementor-widget elementor-widget-n-accordion\" data-id=\"d080af3\" data-element_type=\"widget\" data-settings=\"{&quot;default_state&quot;:&quot;all_collapsed&quot;,&quot;max_items_expended&quot;:&quot;multiple&quot;,&quot;n_accordion_animation_duration&quot;:{&quot;unit&quot;:&quot;ms&quot;,&quot;size&quot;:400,&quot;sizes&quot;:[]}}\" data-widget_type=\"nested-accordion.default\">\n\t\t\t\t\t\t\t<div class=\"e-n-accordion\" aria-label=\"Acorde\u00f3n.

Estos dos son los par\u00e1metros geom\u00e9tricos fundamentales de las torres de acero angular, que determinan directamente su estabilidad estructural y los escenarios en los que pueden utilizarse:<\/p><p>1. Altura sobre el suelo: se refiere a la distancia vertical desde la parte superior de la base de la torre hasta el primer punto principal de soporte de carga de la torre (por ejemplo, el punto de fijaci\u00f3n de los conductores en una torre de transmisi\u00f3n o el nivel de montaje de la antena en una torre de comunicaciones).<\/p><p>2. Repercusi\u00f3n: La altura sobre el suelo debe dise\u00f1arse en funci\u00f3n de las necesidades reales; por ejemplo, las l\u00edneas de transmisi\u00f3n deben evitar \u00e1rboles y edificios (para mantener una \u201cdistancia de seguridad\u201d), y las estaciones base de comunicaciones deben aumentar su altura en funci\u00f3n de la cobertura (normalmente entre 20 y 30 m en las ciudades y entre 30 y 50 m en las zonas suburbanas). Cuanto mayor sea la altura, mayor ser\u00e1 el momento flector que soporta la torre, lo que requiere el uso de perfiles angulares de mayor espesor o secciones transversales de mayores dimensiones para garantizar la resistencia.<\/p><p>3. Distancia entre cimientos: Se refiere a la distancia horizontal entre los centros de dos cimientos adyacentes en la base de la torre (por ejemplo, la \u201cdistancia diagonal entre cimientos\u201d y la \u201cdistancia lateral entre cimientos\u201d de una torre cuadrada).<\/p><p>4. Impacto: Cuanto mayor sea la abertura de la base, mayor ser\u00e1 la capacidad de la torre para resistir el vuelco (al igual que \u201cun tr\u00edpode se mantiene m\u00e1s estable\u201d), pero aumentar\u00e1 la superficie ocupada por los cimientos y los costes de construcci\u00f3n; por lo general, la abertura de la base se dise\u00f1a para que sea mayor en zonas monta\u00f1osas y en zonas con vientos fuertes, mientras que debe reducirse (con una cimentaci\u00f3n m\u00e1s profunda) en zonas urbanas estrechas.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t<details id=\"e-n-accordion-item-2183\" class=\"e-n-accordion-item\" >\n\t\t\t\t<summary class=\"e-n-accordion-item-title\" data-accordion-index=\"4\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-2183\" >\n\t\t\t\t\t<span class='e-n-accordion-item-title-header'><div class=\"e-n-accordion-item-title-text\"> 4. \u00bfQu\u00e9 cargas deben tenerse en cuenta en el dise\u00f1o de torres de perfil angular? \u00bfC\u00f3mo afectan las diferentes cargas al dise\u00f1o estructural? <\/div><\/span>\n\t\t\t\t\t\t\t<span class='e-n-accordion-item-title-icon'>\n\t\t\t<span class='e-opened' ><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-angle-down\" viewbox=\"0 0 320 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M143 352.3L7 216.3c-9.4-9.4-9.4-24.6 0-33.9l22.6-22.6c9.4-9.4 24.6-9.4 33.9 0l96.4 96.4 96.4-96.4c9.4-9.4 24.6-9.4 33.9 0l22.6 22.6c9.4 9.4 9.4 24.6 0 33.9l-136 136c-9.2 9.4-24.4 9.4-33.8 0z\"><\/path><\/svg><\/span>\n\t\t\t<span class='e-closed'><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-angle-right\" viewbox=\"0 0 256 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M224.3 273l-136 136c-9.4 9.4-24.6 9.4-33.9 0l-22.6-22.6c-9.4-9.4-9.4-24.6 0-33.9l96.4-96.4-96.4-96.4c-9.4-9.4-9.4-24.6 0-33.9L54.3 103c9.4-9.4 24.6-9.4 33.9 0l136 136c9.5 9.4 9.5 24.6.1 34z\"><\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-2183\" class=\"elementor-element elementor-element-8566f20 e-con-full e-flex e-con e-child\" data-id=\"8566f20\" data-element_type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-d6f876c elementor-widget elementor-widget-text-editor\" data-id=\"d6f876c\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>1. Los dise\u00f1os de torres de acero angular deben cumplir con la \u201cNorma para el dise\u00f1o de estructuras altas\u201d (GB 51028-2015) y otras normativas. Entre los aspectos clave a tener en cuenta se incluyen las cargas permanentes, las cargas variables y las cargas accidentales. Las implicaciones espec\u00edficas son las siguientes:<\/p><p>\u2460 Cargas permanentes (cargas muertas): Cargas fijas a largo plazo, que incluyen el peso propio de la torre (perfiles angulares, pernos y peso de la plataforma), las cargas de los equipos (conductores, antenas y aisladores) y las cargas de hielo y nieve (el peso del hielo adherido a la torre o a los conductores, calculado en funci\u00f3n del espesor m\u00e1ximo de hielo local).<\/p><p>\u2461 Efectos: Las cargas muertas constituyen la \u201ccarga de cimentaci\u00f3n\u201d del dise\u00f1o estructural y determinan directamente las dimensiones m\u00ednimas de la secci\u00f3n transversal del perfil angular. En zonas con una capa de hielo muy gruesa (como las zonas monta\u00f1osas del noreste y suroeste de China), se debe utilizar perfil angular de mayor espesor (por ejemplo, pasando de L63\u00d76 a L75\u00d78) para evitar la deformaci\u00f3n de la torre debido a cargas pesadas a largo plazo.<\/p><p>\u2462 Cargas variables (cargas vivas): Cargas que act\u00faan a corto plazo o de forma peri\u00f3dica, incluidas las cargas de viento (las m\u00e1s cr\u00edticas, calculadas en funci\u00f3n de la velocidad m\u00e1xima del viento local en un periodo de 50 a\u00f1os), las cargas t\u00e9rmicas (las diferencias de temperatura entre el d\u00eda y la noche o entre estaciones provocan la expansi\u00f3n y contracci\u00f3n t\u00e9rmicas de la torre, lo que genera tensiones adicionales), y las cargas de mantenimiento (el peso de los trabajadores y las herramientas, que suele calcularse como 2-3 personas \u00d7 80 kg\/persona).<\/p><p>\u2463 Impacto: Las cargas de viento son las \u201ccargas de control\u201d en el dise\u00f1o de torres de acero angular: cuanto mayor es la velocidad del viento, mayores son el empuje (a favor del viento) y el par (perpendicular al viento) que act\u00faan sobre la torre. Estas cargas deben mitigarse optimizando la secci\u00f3n transversal de la torre (por ejemplo, reduciendo la superficie expuesta al viento) y aumentando la densidad de los arriostramientos. Las cargas t\u00e9rmicas requieren peque\u00f1os huecos en las uniones de la torre para evitar que las diferencias de temperatura aflojen los pernos o provoquen grietas en el perfil angular de acero.<\/p><p>\u2464 Cargas accidentales: cargas repentinas y de baja probabilidad, incluidas las cargas s\u00edsmicas (calculadas en funci\u00f3n de la intensidad s\u00edsmica local; por ejemplo, en zonas con una intensidad de 8, es necesario reforzar la conexi\u00f3n entre los cimientos y la base de la torre), las cargas por rotura de l\u00ednea (el impacto de la rotura de un conductor de una torre de transmisi\u00f3n; es necesario instalar un \u201cdispositivo de prevenci\u00f3n de rotura de l\u00ednea\u201d en el punto de fijaci\u00f3n del conductor) y cargas por rayos (es necesario dise\u00f1ar un sistema de puesta a tierra para evitar da\u00f1os en la torre causados por los rayos).<\/p><p>\u2465 Principio de selecci\u00f3n: Dar prioridad a la adecuaci\u00f3n entre los \u201crequisitos de carga y las condiciones ambientales\u201d; por ejemplo, se prefiere el Q355ND (resistencia a la niebla salina) en zonas costeras, el Q355B\/Q420C (resistencia a bajas temperaturas) en regiones fr\u00edas y el Q235B (control de costes) para torres de baja carga en zonas suburbanas normales.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t<details id=\"e-n-accordion-item-2184\" class=\"e-n-accordion-item\" >\n\t\t\t\t<summary class=\"e-n-accordion-item-title\" data-accordion-index=\"5\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-2184\" >\n\t\t\t\t\t<span class='e-n-accordion-item-title-header'><div class=\"e-n-accordion-item-title-text\"> 5. \u00bfCu\u00e1les son las etapas clave del proceso de fabricaci\u00f3n de torres de perfil angular? \u00bfC\u00f3mo se garantiza la calidad? <\/div><\/span>\n\t\t\t\t\t\t\t<span class='e-n-accordion-item-title-icon'>\n\t\t\t<span class='e-opened' ><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-angle-down\" viewbox=\"0 0 320 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M143 352.3L7 216.3c-9.4-9.4-9.4-24.6 0-33.9l22.6-22.6c9.4-9.4 24.6-9.4 33.9 0l96.4 96.4 96.4-96.4c9.4-9.4 24.6-9.4 33.9 0l22.6 22.6c9.4 9.4 9.4 24.6 0 33.9l-136 136c-9.2 9.4-24.4 9.4-33.8 0z\"><\/path><\/svg><\/span>\n\t\t\t<span class='e-closed'><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-angle-right\" viewbox=\"0 0 256 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M224.3 273l-136 136c-9.4 9.4-24.6 9.4-33.9 0l-22.6-22.6c-9.4-9.4-9.4-24.6 0-33.9l96.4-96.4-96.4-96.4c-9.4-9.4-9.4-24.6 0-33.9L54.3 103c9.4-9.4 24.6-9.4 33.9 0l136 136c9.5 9.4 9.5 24.6.1 34z\"><\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-2184\" class=\"elementor-element elementor-element-3b6302b e-con-full e-flex e-con e-child\" data-id=\"3b6302b\" data-element_type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-4da9555 elementor-widget elementor-widget-text-editor\" data-id=\"4da9555\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>\u2164. <strong>La fabricaci\u00f3n de torres de perfil angular requiere cinco pasos clave: inspecci\u00f3n de la materia prima \u2192 procesamiento del perfil angular \u2192 montaje de los componentes \u2192 tratamiento anticorrosivo \u2192 inspecci\u00f3n del producto acabado.

Product Introduction<\\\/strong><\\\/p><p>1. Structural Components: Primarily composed of the tower body, crossarms, diagonal members, and foundation. The tower body is the main structure, constructed from multiple sections of angle steel connected by bolts; crossarms are used to secure transmission lines; and diagonal members enhance the tower body's stability and load-bearing capacity.<\\\/p><p>2. Implementation Standards: GB\\\/T 2694-2010 DL\\\/T 5442-2012<\\\/p><p>3. Basic Structure<\\\/p><p>Tower body: The main structure of the angle steel tower, constructed from multiple sections of angle steel connected by bolts. Typically, the structure is square or triangular, offering high overall rigidity and load-bearing capacity.<\\\/p><p>4. Crossarms: Used to secure transmission lines such as wires, cables, and optical fibers, ensuring stable and secure transmission.<\\\/p><p>5. Diagonal members: Enhance the tower body's stability and load-bearing capacity, enabling the angle steel tower to better withstand various loads.<\\\/p><p>6. Foundation: Depending on the geological conditions, independent foundations, strip foundations, pile cap foundations, and other methods can be used to secure the angle steel tower to the ground and withstand the weight of the tower and various external forces.<\\\/p><p>Protection Level: The thickness of the galvanized coating must comply with the requirements of DL\\\/T 764.4-2001.<\\\/p><p><strong>IV Wind Resistance Level<\\\/strong><\\\/p><p>1. According to GB 50009-2012 Code for Loads on Building Structures and GB 50135-2019 Code for Design of Tall Structures, the design must be based on the base wind pressure at the installation site (e.g., 0.3-0.8 kPa; in coastal areas, it can reach over 1.0 kPa). This ensures that the tower will not overturn or suffer structural damage in strong winds (e.g., typhoons of force 10 or above).<\\\/p><p>2. Earthquake Resistance<\\\/p><p>In accordance with the \\\"GB 50011-2010 Code for Seismic Design of Buildings,\\\" based on seismic intensity zoning (e.g., 6-9 degrees), structural stiffness optimization and joint reinforcement design are implemented to ensure the integrity of the tower structure under seismic loads.<\\\/p><p>3. Snow and Ice Load Protection<\\\/p><p>In cold regions, snow loads (e.g., 0.2-0.7 kPa) and ice loads must be considered. Crossarm spacing and tower slope design are optimized to prevent overloads caused by snow and ice accumulation.<\\\/p>\",\"paragraph_spacing\":{\"unit\":\"px\",\"size\":16,\"sizes\":[]},\"_padding\":{\"unit\":\"px\",\"top\":\"20\",\"right\":\"0\",\"bottom\":\"0\",\"left\":\"0\",\"isLinked\":false},\"__globals__\":{\"typography_typography\":\"globals\\\/typography?id=d06f507\"}},\"elements\":[],\"widgetType\":\"text-editor\"}],\"isInner\":true,\"isLocked\":true},{\"id\":\"2e2154e\",\"elType\":\"container\",\"settings\":{\"_title\":\"Tab #2\",\"content_width\":\"full\",\"border_border\":\"solid\",\"border_width\":{\"unit\":\"px\",\"top\":\"1\",\"right\":\"1\",\"bottom\":\"1\",\"left\":\"1\",\"isLinked\":true},\"padding\":{\"unit\":\"px\",\"top\":\"50\",\"right\":\"30\",\"bottom\":\"50\",\"left\":\"30\",\"isLinked\":false},\"__globals__\":{\"border_color\":\"globals\\\/colors?id=secondary\"},\"padding_mobile\":{\"unit\":\"px\",\"top\":\"10\",\"right\":\"10\",\"bottom\":\"10\",\"left\":\"10\",\"isLinked\":true}},\"elements\":[{\"id\":\"0f27574\",\"elType\":\"widget\",\"settings\":{\"title\":\"Product Features   \",\"__globals__\":{\"typography_typography\":\"globals\\\/typography?id=204d764\"}},\"elements\":[],\"widgetType\":\"heading\"},{\"id\":\"f30b232\",\"elType\":\"widget\",\"settings\":{\"editor\":\"<p><strong>I. Core Features<\\\/strong><\\\/p><p>1. Flexible Structural Form<\\\/p><p>Angle steel towers are primarily constructed of angle steel. They can be designed with triangular or quadrilateral cross-sections, depending on height and load requirements (such as wind resistance, ice resistance, and load-bearing capacity). The tower can also be segmented to accommodate installation in complex terrain (such as mountains and hills).<\\\/p><p>2. Stable Load-Bearing Performance<\\\/p><p>Angle steel, as a steel structure, possesses strong compressive, tensile, and shear resistance. The tower is connected through nodes to form a spatial truss structure, which evenly transfers loads (such as deadweight, wind, ice, and snow) to the foundation, ensuring high overall stability.<\\\/p><p>3. High Material Utilization<\\\/p><p>Angle steel's cross-sectional shape is suitable for bearing axial forces and bending moments. Different specifications of angle steel can be selected during design based on the load requirements of different locations, reducing material waste and making it lighter than structures such as concrete towers.<\\\/p><p>4. High Demountability<\\\/p><p>Most angle steel towers are bolted together rather than welded, making them easier to transport, install, and maintain. For relocation or renovation, they can be disassembled and reassembled, reducing secondary construction costs.<\\\/p><p>5. Structural Characteristics: Stable and Efficient Lattice Design<\\\/p><p>The mechanical advantages of triangular units, the flexibility of modular assembly, and the economical stratification of load bearing.<\\\/p><p>6. Material Characteristics: Excellent mechanical properties and strong load-bearing capacity.<\\\/p><p>7. Application Characteristics: High strength, good plasticity and toughness, and uniform mechanical properties facilitate functional expansion in various terrains and environments.<\\\/p><p>8. Engineering Characteristics: Convenient construction and maintenance, light weight, and easy transportation and installation.<\\\/p><p><strong>II. Main Advantages<\\\/strong><\\\/p><p>1. Adaptability to Complex Environments<\\\/p><p>Angle steel towers are mostly made of carbon steel or galvanized steel. After anti-corrosion treatment (such as galvanizing and painting), they are highly weather-resistant and can withstand long-term use in harsh environments such as high temperature, high humidity, coastal areas (salt spray), and deserts, with a service life of over 30 years.<\\\/p><p>2. Convenient and Efficient Construction<\\\/p><p>Components are prefabricated in factories with high precision. On-site installation does not require large lifting equipment (for small and medium-sized towers). The assembly process is simple and the construction period is short, making them suitable for projects in remote areas or with limited space.<\\\/p><p>3. Cost Controllability<\\\/p><p>Compared to steel pipe towers and concrete towers, angle steel material costs are lower, and transportation and installation costs are reduced. This makes it particularly economical for medium-to-low height towers (under 50 meters).<\\\/p><p>4. Low Maintenance<\\\/p><p>The open structure, with exposed components, facilitates inspection for problems such as corrosion and loose bolts. Maintenance requires targeted replacement of damaged components, eliminating the need for extensive disassembly.<\\\/p>\",\"_padding\":{\"unit\":\"px\",\"top\":\"20\",\"right\":\"0\",\"bottom\":\"0\",\"left\":\"0\",\"isLinked\":false},\"__globals__\":{\"typography_typography\":\"globals\\\/typography?id=d06f507\"},\"paragraph_spacing\":{\"unit\":\"px\",\"size\":16,\"sizes\":[]}},\"elements\":[],\"widgetType\":\"text-editor\"}],\"isInner\":true,\"isLocked\":true},{\"id\":\"764f307\",\"elType\":\"container\",\"settings\":{\"_title\":\"Tab #3\",\"content_width\":\"full\",\"padding\":{\"unit\":\"px\",\"top\":\"50\",\"right\":\"30\",\"bottom\":\"50\",\"left\":\"30\",\"isLinked\":false},\"border_border\":\"solid\",\"border_width\":{\"unit\":\"px\",\"top\":\"1\",\"right\":\"1\",\"bottom\":\"1\",\"left\":\"1\",\"isLinked\":true},\"__globals__\":{\"border_color\":\"globals\\\/colors?id=secondary\"},\"padding_mobile\":{\"unit\":\"px\",\"top\":\"10\",\"right\":\"10\",\"bottom\":\"10\",\"left\":\"10\",\"isLinked\":true}},\"elements\":[{\"id\":\"9872304\",\"elType\":\"widget\",\"settings\":{\"title\":\"Product structure\",\"__globals__\":{\"typography_typography\":\"globals\\\/typography?id=204d764\"}},\"elements\":[],\"widgetType\":\"heading\"},{\"id\":\"b1b2cc5\",\"elType\":\"widget\",\"settings\":{\"editor\":\"<p>Detailed Explanation of Angle Steel Tower StructureAn angle steel tower is a lattice steel structure constructed with equal-leg angle steel and unequal-leg angle steel as core load-bearing components, connected by bolts.

Connection and Fixing System: Key to Ensuring Structural Integrity<\\\/strong><\\\/p><p>All components of the angle steel tower are assembled using bolted connections. The reliability of the connection system directly determines the overall stability of the tower. It primarily includes the following core components:<\\\/p><p><strong>1. Connection Bolts<\\\/strong><br \\\/>Type and Specifications: Use \\\"coarse hexagonal head bolts\\\" (GB\\\/T 1228), made of Q235B or Q355B, with a strength grade of 8.8 (high-strength bolts). Bolt specifications are determined by the loads on the members: M24-M30 bolts are used for the main members of the tower, and M16-M20 bolts are used for the web members. Each joint should have at least four bolts (at least six for tension joints).<\\\/p><p>Installation Requirements: Bolts must be secured with a double nut (after tightening the upper nut, unscrew the lower nut 1\\\/4 turn before tightening). The bolts must have at least two exposed threads. The bolt hole diameter should be 1-2 mm larger than the bolt diameter (e.g., an M24 bolt with a \\u03c625.5 mm hole) to avoid installation stress.<\\\/p><p><strong>2.

Specific tasks and cycles are as follows:<\\\/strong><\\\/p><p><strong>1. Daily Maintenance Content<\\\/strong><\\\/p><p>\\u2460 Visual Inspection:<\\\/p><p>Inspect the tower angle steel for deformation, cracks, or rust (focus on bolted joints and areas near the tower base);<\\\/p><p>Check for loose or missing bolts (use a torque wrench for spot checks and tighten any loose bolts immediately);<\\\/p><p>Check for peeling or bulging of the anti-corrosion coating (if 10% or more of the zinc coating has fallen off, reapply anti-rust paint).<\\\/p><p>\\u2461 Functional Inspection:<\\\/p><p>Check ground resistance (once annually, recheck before the rainy season. If resistance exceeds the specified value, clean the ground grid or add a new grounding electrode);<\\\/p><p>Check the security of ladders and platform guardrails (to prevent falls);<\\\/p><p>Check the conductor attachment points for wear and tear and the integrity of insulators on power towers (and antenna mounting for communications towers). \\u2462 Environmental Cleaning:<\\\/p><p>Remove weeds and debris around the tower and foundation to prevent root damage to the foundation.<\\\/p><p>Towers in coastal\\\/industrial areas should be regularly cleaned of salt spray and dust to reduce corrosion.<\\\/p><p><strong>2. Inspection Frequency<\\\/strong><\\\/p><p>\\u2460 Routine Inspection: Monthly (appearance and simple functional inspection, which can be performed via remote video inspection or on-site spot checks);<\\\/p><p>\\u2461 Detailed Inspection: Semi-annually (comprehensive appearance inspection, bolt torque inspection, and ground resistance test);<\\\/p><p><strong>3. Special Inspections:<\\\/strong><\\\/p><p>\\u2460 After extreme weather (heavy rain, typhoons, earthquakes, and heavy snow): Emergency inspections should be conducted within 24 hours, focusing on checking for tower tilt and foundation settlement.<\\\/p><p>\\u2461 Towers over 15 years old: Structural strength testing should be conducted annually (a professional organization should use a stress tester to test the stress on the angle steel).<\\\/p>\",\"_padding\":{\"unit\":\"px\",\"top\":\"20\",\"right\":\"0\",\"bottom\":\"0\",\"left\":\"0\",\"isLinked\":false},\"__globals__\":{\"typography_typography\":\"globals\\\/typography?id=d06f507\"},\"paragraph_spacing\":{\"unit\":\"px\",\"size\":16,\"sizes\":[]}},\"elements\":[],\"widgetType\":\"text-editor\"}],\"isInner\":true,\"isLocked\":true}]}],\"isInner\":true,\"isLocked\":true}]}],\"isInner\":false}]"],"_uag_page_assets":["a:9:{s:3:\"css\";s:263:\".uag-blocks-common-selector{z-index:var(--z-index-desktop)
