Connecting structure and method for integrated profile steel and cross beam

Abstract

The invention discloses a connecting structure and method for integrated profile steel and a cross beam. The connecting structure comprises a connector arranged on the integrated profile steel, a tenon arranged at the end of the cross beam and brake iron, the edge of the end of the tenon exceeds the side wall of the tenon to form a limiting edge, a mounting cavity is formed in the connector, two wedge-shaped blocks are arranged on the two sides of the mounting cavity, the two wedge-shaped blocks are arranged in a spaced mode and form an installation seam gradually narrowing from top to bottom,the tenon is placed into the installation cavity from top to bottom, the limiting edge is embedded into the installation seam, and the brake iron is inserted into a gap between the limiting edge andthe installation seam to fasten the limiting edge. The connecting structure of the integrated structural steel and the cross beam replaces an original connecting mode combined bolt connection and welding, rapid and reliable on-site installation is achieved through splicing and clamping, the connecting gap is reduced, welding operation is omitted, the connecting strength is guaranteed, the on-siteassembly difficulty is lowered, and a new thought is provided for the installation mode of the cross beam. The invention further discloses a connecting method of the integrated profile steel and the cross beam.

Description

technical field [0001] The invention relates to the technical field of integrated profiled steel installation, in particular to a connection structure and connection method between integrated profiled steel and a beam. Background technique [0002] At present, steel structures are used more and more in the field of building structures, and various new forms of steel structures are emerging, which have been applied in the field of engineering, and the number is also rising, with broad prospects. Integrated section steel is a kind of steel structure, especially in the height direction, the tailor welding connection method has great advantages, which reduces the difficulty of on-site construction and improves construction efficiency. [0003] However, when installing a crossbeam between two integrated steel sections on site, the current method is to first connect them with bolts and then weld them into shape. In this method, there are connection gaps in the bolt connection, whi...

Problems solved by technology

[0003] However, when installing a crossbeam between two integrated steel sections on site, the current method is to first connect them with bolts and then weld them into shape. In this method, there are connection gaps in the bolt connection, which reduces reliability, and the welding workload on site is large, which is not conducive to high altitude. Occasional operation, welding quality is difficult to guarantee, labor intensity is high, construction efficiency is low, and on-site welding smoke discharge is large, which needs further optimization
