Description

Pole type communication steel tower mast

technical field

The utility model relates to a pole-holding type communication steel tower mast, which belongs to the field of communication civil equipment and is mainly used in township-level communication network scenarios in hilly areas.

Background technique

In the current rural communication network, communication masts mainly use two types of poles: H-shape pole and equal-diameter pole. intensity and difficulty. At the same time, since steel hinges and anchor plate foundations need to be arranged in four directions, each site occupies a large area, resulting in serious waste of land.

Contents of the invention

In order to solve the problems existing in the existing towers, the purpose of the utility model is to provide a pole-mounted communication steel tower mast, so as to smoothly promote the construction of rural communication networks in hilly areas.

In order to achieve the above purpose, the technical solution of the utility model is: a pole-holding type communication steel tower mast, including a main pole and two diagonal braces, an antenna platform is arranged on the upper side of the main pole, and the upper end of the main pole passes through The hoop is equipped with a lightning rod, and the lower end of the main rod is provided with a main rod base fixed on the main rod foundation through anchor bolts. The diagonal brace base is fixed on the diagonal brace foundation by anchor bolts.

Further, several auxiliary rods are arranged between the main rod and the two diagonal braces.

Further, RRU hanging rods are provided on the lower peripheral side of the main rod.

Further, the antenna platform includes three antenna brackets symmetrically welded on the upper peripheral side of the main pole.

Further, the main rod foundation and the diagonal brace foundation are distributed in an isosceles right triangle.

Further, the main rod and the diagonal brace are screwed together by multi-section rod segments through connecting flanges. the

Compared with the prior art, the utility model has the following advantages:

(1) The tower-mast structure can flexibly set steel structure splicing nodes, and use the splicing process to reduce the handling strength and difficulty of the tower-mast parts in hilly areas;

(2) The material properties of the tower mast are developed towards light weight and high strength on the basis of ensuring the ductility of steel fibers, which saves the use of tower mast materials, and also reduces the workload of on-site handling to a certain extent, greatly improving the construction of the station. the feasibility of

(3) The tower mast replaces steel hinge stay wires and anchor plates by diagonal braces, which effectively reduces the footprint of the tower mast base station and effectively saves land;

(4) In areas where the traffic is more convenient and the geological conditions permit, the tower mast can use a prefabricated foundation to further facilitate construction and improve station construction efficiency.

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
