Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit steel perimeter purlin support, in particular to a foundation pit steel perimeter purlin support structure. Background Art

[0002] Steel purlins are also called steel fences or steel fences. Generally, two or more steel sections of the same model and length are used for splicing. The splicing quality must be guaranteed during the splicing process to ensure that multiple steel sections are subjected to force together. Steel purlins are used to connect support and retaining piles. In order to ensure the stable fixation of the steel purlins during the construction of the trench foundation pit, it is necessary to support the steel purlins to ensure that the steel purlins have a stable support structure.

[0003] At present, when supporting the steel perimeter purlins in the ditch foundation pit, the method is mainly to first fix a proper amount of support members on the steel perimeter purlins, and fix a cross plate on each support member, and then install a support rod perpendicular to the cross plate on two cross plates parallel to each other on both sides of the steel perimeter purlins, so as to support the steel perimeter purlins. Although the support and protection of the steel perimeter purlins can be achieved under the above-mentioned support structure, the support of the ditch foundation pit steel perimeter purlins is achieved by assembling each accessory one by one during use, resulting in a relatively cumbersome installation process of the entire support structure, which not only increases the labor intensity of the support structure during installation, but also makes the support efficiency of the ditch foundation pit steel perimeter purlins relatively low.
