Screw-thread steel connecting piece for building framework

Abstract

The invention relates to the related technical field of building construction, in particular to a screw-thread steel connecting piece for a building framework. The screw-thread steel connecting piece for the building framework comprises first sectional material, a second sectional material, a first connecting plate and a second connecting plate, the first sectional material and the second sectional material are steel structures with the same size, and the first connecting plate and the first sectional material are integrally formed. The first connecting plate is arranged on the first sectional material, a second connecting plate is arranged on the second sectional material, a threaded hole is formed in the first connecting plate, a mounting hole formed by combining a mounting cavity and a through hole is formed in the second connecting plate, an elastic piece formed by combining a lower supporting plate, a supporting spring and an upper supporting plate is arranged in the mounting cavity, a first limiting protrusion is integrally formed on the upper surface of a plate body of the upper supporting plate, a second limiting protrusion is integrally formed on the lower surface of a nut of a fixed bolt, and therefore the connecting stability between the first sectional material and the second sectional material is guaranteed through the limiting effect of the first limiting protrusion and the second limiting protrusion.

Description

technical field [0001] The invention relates to the technical field related to building construction, in particular to a threaded steel connector for a building frame. Background technique [0002] Building construction is a production process that people use various building materials and mechanical equipment to build various building products in a certain space and time according to a specific design blueprint. It includes the entire production process from construction preparation, groundbreaking to project completion acceptance. In this process, construction preparation, construction organization design and management, earthwork engineering, blasting engineering, foundation engineering, steel reinforcement engineering, formwork engineering, scaffolding engineering, concrete engineering, prestressed concrete engineering, masonry engineering, steel structure engineering, and timber structure will be carried out. Engineering, structural installation engineering, etc., and ...

Problems solved by technology

In this process, construction preparation, construction organization design and management, earthwork engineering, blasting engineering, foundation engineering, steel reinforcement engineering, formwork engineering, scaffolding engineering, concrete engineering, prestressed concrete engineering, masonry engineering, steel structure engineering, and timber structure will be carried out. Engineering, structural installation engineering, etc., and the threaded steel structure on the traditional building frame in the construction process is welded or bolted, and the welded connection is difficult to adjust the subsequent position, while the traditional bolted connection, the connection point bolts The risk of loosening is prone to occur. For this reason, the present invention proposes a threaded steel connector for building frames to solve the above problems
