Description

Technical Field

[0001] The utility model belongs to the field of steel structure construction, in particular to a butt joint device for steel structure construction. Background Art

[0002] Steel components refer to structural components made of angle steel, steel plates, channel steel, H-shaped steel or their combination. They have the comprehensive advantages of light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery and less environmental pollution. Their bearing capacity affects the quality of steel structure construction and is an indispensable part of steel structure construction.

[0003] The patent application with announcement number CN220080318U discloses a steel member docking device for steel structure engineering construction, including: a support truss and a docking steel plate, a connecting steel bar is arranged on the top of the docking steel plate, a connecting assembly is arranged inside and outside the docking steel plate, a splicing assembly is arranged inside the support truss, and the connecting assembly includes a fixing seat fixedly connected to the inside of the docking steel plate. The steel member docking device for steel structure engineering construction clamps the support truss to the inside of the docking steel plate, when the clamping block contacts the docking steel plate, the clamping block will shrink to the inside of the support truss, when the clamping block is located at the top of the clamping groove, the compressed spring will drive the slide plate and the clamping block to reset, fix the support truss, and at the same time, the rotation of the torsion cap drives the threaded rod to rotate, the rotation of the threaded rod drives the threaded block to move left and right, and the threaded block will drive the fixing hoop to move left and right, so that the position of the connecting steel bar can be adjusted, so as to achieve the effect of convenient operation and high stability during steel structure construction.

[0004] However, the above technology has the following disadvantages when used:

[0005] The paragraph 0027 of the above-mentioned document describes that “by clamping the support truss into the inside of the butt steel plate, when the clamping block contacts the butt steel plate, the clamping block will shrink into the support truss, and when the clamping block is at the top of the clamping slot, the compressed spring will drive the slide plate and the clamping block to reset, fixing the support truss, and at the same time, rotating the torsion cap drives the threaded rod to rotate, and the rotation of the threaded rod drives the threaded block to move left and right, and the threaded block drives the fixing hoop to move left and right, so that the position of the connecting steel bar can be adjusted, achieving the effect of convenient operation and high stability during steel structure construction”. Combined with the attached manual Figure 3 It can be seen that since the spring is easily deformed by the external force during processing, the block is displaced, and the block is easily slipped out of the inside of the slot, which in turn causes the supporting truss to slip out of the docking steel plate.

[0006] Therefore, a docking device for steel structure construction is proposed to solve the above-mentioned drawbacks. Utility Model Content
