Novel duct piece steel structural framework and welding method thereof

Abstract

The invention discloses a novel duct piece steel structural framework, comprising horizontal main reinforcements (22), longitudinal main reinforcements (23), welding spots (24), an injected hole embedded part (25), and fixing hole embedded parts (26). The horizontal main reinforcements (22) are longitudinally provided with the longitudinal main reinforcements (23). The intersection of each longitudinal main reinforcement (23) and each horizontal main reinforcement (22) is provided with the welding spot (24). The middle position of a framework net formed by the plurality of longitudinal main reinforcements (23) and the plurality of horizontal main reinforcements (22) is provided with the injected hole embedded part (25). Symmetric positions of the front and the rear of the framework net are provided with three groups of fixing hole embedded parts (26). Symmetric positions of the left and right of the framework net are provided with two groups of fixing hole embedded parts (26). The duct piece steel structural framework is formed by improving a process and changing manual installation of hooked bars into direct welding. In addition, equipment for welding the framework is improved, so as to greatly save installation time of the hooked bars and save labor amount, and improve production efficiency.

Description

technical field [0001] The invention relates to a segment steel structure skeleton, in particular to a novel segment steel structure skeleton and a welding method thereof. Background technique [0002] At present, with the substantial improvement of the quality of urban life, more and more people enter the urban life, and the traffic pressure increases sharply. For this reason, the convenient and fast urban light rail came into being and was favored by the people. For this reason, most The city began to build the subway light rail. Since some road sections need to pass through the ground, the tunnel produced by the shield needs to use steel structure concrete segments to reinforce the tunnel wall. The main reinforcement is welded. The traditional process requires the upper and lower ends of the longitudinal main reinforcement to be clamped with hook reinforcement to enhance the strength of the longitudinal main reinforcement. It needs to be completed on a welding frame. Due ...

[0002] At present, with the substantial improvement of the quality of urban life, more and more people enter the urban life, and the traffic pressure increases sharply. For this reason, the convenient and fast urban light rail came into being and was favored by the people. For this reason, most The city began to build the subway light rail. Since some road sections need to pass through the ground, the tunnel produced by the shield needs to use steel structure concrete segments to reinforce the tunnel wall. The main reinforcement is welded. The traditional process requires the upper and lower ends of the longitudinal main reinforcement to be clamped with hook reinforcement to enhance the strength of the longitudinal main reinforcement. It needs to be completed on a welding frame. Due to the high hardness of the steel reinforcement, manual engagement is difficult. The traditional bench used for the sheet steel structure skeleton bench is the same height at both ends. It is laborious for the workers to install and weld the transverse main reinforcement (need to bend down), the welding time is longer, and the welding efficiency is lower.
