Communication three turrets of supporting oneself
Technical field
The utility model belongs to communication device class, specifically is a kind of communication three turrets of supporting oneself.
Background technology
Cubic Guywire tower and cubic self-supporting steel tower are mainly adopted in the installation of existing mobile communication antenna feeder, and what king-post adopted is 90 ° of angle steel or steel pipe, whole tower body Heavy Weight, and floor space is big, and expense height, especially Guywire tower usually are subjected to the restriction in geographical position.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of communication self-support three turrets in light weight, that floor space is little, rational in infrastructure are provided.
The technical solution of the utility model is as follows:
A kind of communication comprises column foot, tower body, antenna holder with three turrets of supporting oneself, and lightning rod is characterized in that: tower body is formed by connecting by many king-posts, and king-post adopts 60 ° of angle steel and waling stripe to connect into the triangle turriform, and the tower body cross section is the equilateral triangle shape.
The utility model is owing to adopted 60 ° of angle steel and waling stripe to surround the equilateral triangle turriform, and structure is light and handy, firm, in light weight, the backguy of having saved tower body, and floor space is little, and is convenient and practical.

The specific embodiment
As shown in Figure 1, 2, a kind of communication three turrets of supporting oneself, comprise column foot 1, tower body, antenna holder 2, lightning rod 3, it is characterized in that: tower body is formed by connecting by many king-posts, and king-post adopts 60 ° of angle steel 4 to connect into the triangle turriform by waling stripe 5, and the tower body cross section is the equilateral triangle shape, on the side plane of tower body, there is wedge 6 to connect, in order to reinforce.
As shown in Figure 3,60 ° of angle steel 4 of the present utility model bend to three sections, two hexagonal angles of three intersegmental formations, and a section of bent intermediate is shorter, becomes 60 ° behind two elongated segments in addition.
King-post of the present utility model and column foot 1 are by bolton, and king-post is connected with waling stripe 5 usefulness bolts or welds, and the multistage king-post connects into a tower body with bolt.
