Mounting structure of large-size cross beam on integrated steel and construction method

Abstract

The invention discloses a mounting structure of a large-size cross beam on integrated steel. According to the mounting structure, a reinforcement cage tenon is arranged at the end of the large-size cross beam, a limiting edge protrudes out of the reinforcement cage tenon, a supporting connector is arranged on the integrated steel, mounting seams are formed in the supporting connector, when the reinforcement cage tenon and the supporting connector are assembled, the limiting edge is embedded into the upper mounting seam and the lower mounting seam at the same time, a first brake iron and a second brake iron are inserted into gaps of the corresponding mounting seams, the reinforcement cage tenon is supported by a bottom plate, a tension bolt penetrates through the bottom plate and is in threaded connection with the second brake iron, a cover plate for limiting the upper portion of the first brake iron is arranged on the first brake iron, a fastening bolt penetrates through the cover plate and is in threaded connection with the second brake iron, and the fastening bolt is in threaded connection with the upper end of the reinforcement cage tenon. According to the mounting structure, reliable fixation of the tenon is fully guaranteed, the connection gap is eliminated, the pre-tightening force is improved, the connection strength is guaranteed, and the field assembly difficulty is reduced. The invention further discloses a construction method of the large-size cross beam on the integrated steel.

Description

technical field [0001] The invention relates to the technical field of integrated section steel, in particular to an installation structure and construction method of a large-size beam on the integrated section steel. 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] When installing beams on integrated steel buildings, the current method is to first connect them with bolts and then weld them into shape. In this method, there is a connection gap in the bolted connection, and the on-site welding workload...

AI Technical Summary

Problems solved by technology

In this method, there are connection gaps in the bolted connection, and the welding workload on site is large, the emission of welding smoke is large, the labor intensity is high, and the construction efficiency is low.

In addition, due to load-bearing requirements, some beams are large in size, especially in the height direction, and multiple bolts need to be installed, otherwise the installation reliability will be greatly reduced, and the construction difficulty will be further increased.
