Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a purlin brace fixing structure with adjustable height. Background Art

[0002] In the construction industry, purlins are important components that support the roof and wall enclosure panels. When designing the wall door and window openings, the window sills and door and window lintels are usually designed as single C purlins or double C-mouth purlins. The tie rods are installed at the 1 / 3 position close to the indoor web of the purlin. Therefore, when processing the purlins, in order to ensure the installation of the tie rods between the purlins, a rectangular 5mm square plate needs to be welded at the two short legs of the purlins to ensure that the tie rods between the purlins do not pass through the purlin webs to affect the installation of the edge and door and window frames. At present, the node form of this purlin support in the industry is relatively simple, with low efficiency and high labor costs. The project processing progress and installation quality are difficult to guarantee, which increases the cost of the enterprise.

[0003] To solve the above problems, the utility model patent with publication number CN219431003U discloses a C-shaped wall purlin upper tie rod connection node structure. The device is fixed by welding a U-shaped support to the belly of the purlin, and then the tie rod and the U-shaped support are fixedly connected with nuts, which solves the technical problem that the protruding part of the tie rod in the traditional installation method affects the installation of doors and windows. However, the purlin spacing and the height from the ground of this structure are relatively fixed. When the distance between the purlins needs to be fine-tuned, the tie rod connecting the purlins needs to be disassembled before replacing the new purlins, which greatly delays the construction time of the workers. In addition, the purlins themselves are galvanized materials. Welding the U-shaped support plate to the purlins will destroy the galvanized treatment on the surface of the purlins themselves, which not only affects the anti-corrosion properties of the purlins but also is not conducive to installation.

[0004] How to solve the above problems has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] The utility model aims to provide a purlin brace fixing structure which is easy to install and has good anti-corrosion effect and can adjust the height.
