Radio and television towers, referred to as radio and television towers, are mainly used to house radio and television antennas. And most of them are built on the top or beside the radio and television buildings in cities and towns. Therefore, in addition to meeting the structural technological requirements of radio and television antennas, the structure of the tower structure also needs to be beautiful in shape and harmonious with the surrounding environment.
The facade outline of radio and television towers usually adopts a polygonal shape, which is not only beautiful but also reduces the stress on the foundation and improves the stability of the entire tower. Plane cross-sectional shapes include triangle, quadrilateral, hexagon, etc. Polygonal mesh structures can be used in special cases. The web pole shapes of radio and television towers include single inclined pole type, cross type, diamond shape, K type and subdivided type. Single inclined web pole is used on small radio and television towers. Generally it is a rigid inclined rod. Cross-type web rods are widely used, and diagonal rods can be made into two types: rigid and flexible. Flexibility can be divided into prestressed and non-prestressed.
The radio and television tower is equipped with platforms for crafts, viewing and other purposes. Its level, number and layout height must be determined according to the usage requirements. The shape of the platform depends on the cross-section of the tower body. The components of the platform structure are generally made of angle steel, channel steel, I-beam and other section steels. In order to facilitate high-altitude installation, the components are first welded to form hoisting units, and each unit is connected with Bolted.
