Abstract

The utility model relates to a communication antenna sustaining rod frame comprising two main posts, the two main posts are vertically arranged on a ground base in parallel, one main post is on the left side, the other main post is on the right side, the left main post is connected with the right main post through a horizontal member, and each main post is provided with two pulling wires which are connected with the ground base to play the fastening and the fixing functions. The sustaining rod frame of the utility model has the advantages that the vertical section presents a H shape, the structure is very simple, the hoisting construction can be carried out on site by adopting common tools, the construction period is short; the occupied space is small, the site selection is very easy, and the whole stability can be well guaranteed through the ground pulling wires.

Description

The communication antenna bracing member

Technical field:

The utility model relates to a kind of bracing member structure that is used for fixing communication antenna.

Background technology:

In order to satisfy the develop rapidly of the communications industry, must set up a considerable amount of mobile communication antennas and could satisfy people higher requirements such as network service quality, signal coverings; So progressively set up a considerable amount of mobile communication antennas in densely inhabited district, and the pylon cost that will set up these mobile communication antennas is also considerably high, at some limit stations or because of it antenna to be hung high request be not so high in the repeater, reasons such as the communication equipment of base station is also comparatively simple and easy can consider to design simple, the more convenient support tower structure of constructing of some structures.

Summary of the invention:

It is a kind of simple in structure, reasonable in design that the purpose of this utility model is to provide, the communication antenna bracing member of low cost of manufacture.

The utility model communication antenna bracing member is characterized in that: vertically be arranged on two mobile jibs on the ground about comprising side by side, be connected and fixed by horizontal member between two mobile jibs, be equipped with two on the every mobile jib and be connected the backguy that is strained and fixed with the ground pedestal.

Be the H type on the utility model bracing member facade, structure is simple in the extreme, and the field by using general purpose tool gets final product lifting construction, and short construction period; Floor space is little, addressing also is easy to; Just can guarantee whole stability well by the ground backguy.

Description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model.

Embodiment:

The utility model communication antenna bracing member 1, it is characterized in that: vertically be arranged on two

mobile jibs

2,3 on the ground about comprising side by side, be connected and fixed by horizontal member 4 between two mobile jibs, be equipped with two on the every mobile jib and be connected the backguy that is strained and fixed with ground pedestal 5.

In order further to reduce the floor space of bracing member, the pedestal that the utility model is connected with right mobile jib backguy 6 is positioned at left mobile jib left side, and the pedestal that is connected with left mobile jib backguy 7 is positioned at right mobile jib right side,---H type bar itself takes up an area of less than 2m ², contain the about 18m of backguy scope ²Such backguy form is reasonable more---and the vertical pulling form is all adopted in former Guywire tower backguy, existing H type bar is used the oblique pull-shaped formula of intersection instead, both guaranteed the monolithic stability of H type bar, solved again and taken up an area of big contradiction (, can reduce 2.9m) if adopt vertical pulling form ground length to be about 9.3m greater than the existing 6.4m that draws that intersects.

Reliable and stable for what connect, the pedestal that connects same mobile jib backguy is with respect to two mobile jib line symmetries.

The level that can also be connected with between two mobile jibs connects auxiliary member 8 to increase its rigidity, stability.

Above-mentioned bracing member is provided with lightning rod 9.

In sum, the utlity model has that addressing is easy, floor space is little, easy construction, cost are low, and the construction period is short etc. Remarkable advantage will be conducive to the utility model being extensive use of in station, limit or Nogata station.
