Building construction steel structure temporary bearing frame

Abstract

The invention discloses a building construction steel structure temporary bearing frame which comprises a plurality of outer upright rods and a plurality of inner upright rods. A stable bottom frame is jointly connected with the bottoms of the outer upright rods and the inner upright rods, a middle-layer bearing frame is arranged between the outer upright rods and the inner upright rods, a top-layer bearing frame is arranged on the tops of the outer upright rods and the inner upright rods, a plurality of oblique support rods are arranged between the middle-layer bearing frame and the top-layerbearing frame in a connected manner, a scissors support frame is arranged between the outer upright rods on the leftmost side and the rightmost side of the building construction steel structure temporary bearing frame in a connected manner, inclined stress columns are connected with the outer side of the top-layer bearing frame, and a balance bottom frame is connected with the bottoms of the inclined stress columns. The building construction steel structure temporary bearing frame has the advantages that the oblique support rods and the scissors support frame are arranged on an integral mounting frame, the structural strength of the building construction steel structure temporary bearing frame can be reinforced by the aid of triangular stability principles, the stability of the building construction steel structure temporary bearing frame can be greatly reinforced by the inclined stress columns and the balance bottom frame, the strength of every two cross connecting rods can be greatly reinforced by pinning type cross fasteners, and accordingly the stability and the loading carrying capacity of the building construction steel structure temporary bearing frame can be improved.

Description

technical field [0001] The invention relates to the technical field of building tools, in particular to a steel structure temporary load-bearing frame for building construction. Background technique [0002] With the acceleration of urbanization, urban construction has also obtained unprecedented opportunities for development. In order to avoid unnecessary waste, a large number of temporary facilities are used in the process of urbanization. Needless to say, scaffolding support drawings in building construction, commonly used temporary facilities include temporary stands of stadiums, large screen support frames, temporary overpasses, Cable bridge, temporary stage, temporary lighting and sound layout, etc. Among the temporary facilities used, the most frequently used supporting structure is the prefabricated temporary frame. This kind of frame is flexible, safe and reliable, less limited by the site, easy to install, easy to disassemble, and reusable. Compared with the weld...

AI Technical Summary

Problems solved by technology

[0006] The existing temporary load-bearing frame for building construction basically meets the current workmanship requirements. However, the lateral load-bearing capacity and vertical load-bearing capacity are insufficient. When there are many operators or many tools are used, the frame may have potential safety hazards, and the frame There may be different degrees of bending of the connecting rod after long-term use, which greatly reduces the practical life of the frame
