The new control tower is composed of three three-pipe communication towers: the tower base, including (1), Tower (2), rails, diagonals (3), antenna support (4), lightning (5), Tower socket device ( 6), characterized in that: Tower (2) pipe using Tower socket device (6) is connected, and then bolted with diagonals (3), Tower socket device (6) the use of equal diameter pipe. Three features of the new communication tower using seamless steel tube tower material as the wind load factor is small, strong wind resistance. Tower with external flange connection, bolts tension, not easy to damage, reduce maintenance costs. Tower are triangular layout, save steel. Root to open a small, small footprint, conservation of land resources, convenient location. Tower, light weight, the new clover style cutting board basis, reducing the cost base. Truss structure design, convenient transportation and installation, short construction period. Tower design wind load curves, smooth lines, the case of rare event of hurricane easily collapse, reducing livestock casualties. Designed to meet the national steel tower mast design specifications and design rules, structural safety and reliability. Use: field self-tower, the roof tower. [1] The main control tower three parameters: the basic design basis: steel design specification (TJ17-74) Basic parameters: design wind speed: 35 meters per second shock: 8 wrapped in ice: 5-10 mm verticality: 1/1000 Suitable temperature: -45C- + 45C embalmed: galvanized life: 30 years
