High-Quality Galvanized 4 Legs Telecom Angle Steel Tower
Product Description
4 Legged Angular Steel Tower
Radio and television tower is called radio and television tower for short, which is mainly used to place radio and television antenna. Most of them are built on the top or side of the city and town radio and television buildings.
Therefore, the structure of the tower not only meets the technological requirements of the radio and television antenna, but also needs beautiful shape and coordination with the surrounding environment.
The elevation profile of radio and television tower usually adopts multi fold line, which is not only beautiful, but also can make the foundation stress small and the whole tower stability good. The shape of plane section includes triangle, quadrilateral, hexagon and so on. In special cases, polygonal mesh structure can be used. The web members of radio and television tower are of monoclinic, crisscross, rhombic, K-type and subdivided shapes. Monoclinic web members are used in small radio and television towers. Generally, it is a rigid inclined bar. The diagonal member can be made into rigid and flexible. Flexibility can be divided into prestressed and non prestressed.
The radio and television tower is equipped with a platform for process, Liaowang and other purposes. Its level, number and layout height should be determined according to the use requirements. In general, the I-steel is used to connect the members of the platform and the U-steel is used to connect the members of the platform.
