Truss combined beam and upper and layer connected light steel structure and construction method thereof

Abstract

The invention discloses a truss combined beam and upper and layer connected light steel structure and a construction method thereof. The light steel structure comprises upper wall sheet columns distributed at intervals, lower wall sheet columns distributed at intervals, upper wall sheet column lower connecting pipes connected among the lower parts of the upper wall sheet columns, lower wall sheet column upper connecting pipes connected among the upper parts of the lower wall sheet columns, and truss combined beams connected between the upper wall sheet columns and the lower wall sheet columns through upper and lower connectors, wherein the upper and lower connectors are beam passing buckles, the web plates of the beam passing buckles consist of upper web plates and lower web plates, a square connecting port is formed between the upper web plates and the lower web plates, upper chord member connecting plates are extended from the left and right sides of the square connecting ports, and the upper chord member connecting plates and side plates of the beam passing buckles are positioned in the same plane. Through the light steel structure, the structural stability of a light steel keel house system is enhanced, and the floor surface beams, the connecting pipes and the floor panels do not easily vibrate.

Description

technical field [0001] The invention relates to a light steel structure and a construction method thereof, in particular to a light steel structure used in a light steel keel system building and a construction method thereof. Background technique [0002] The light steel keel housing system has the advantages of light weight, good seismic performance, small wall thickness, good thermal insulation performance, low construction pollution, fast construction speed, no need for support boards, convenient pipeline layout, less residual waste, and can promote energy conservation and environmental protection , can be produced in a factory and can promote the development of the construction industry, so it has been widely used in the construction industry at home and abroad in recent years. [0003] In the current light steel keel building system, two methods are adopted for the wall load-bearing truss and truss composite beam: 1. The traditional C-shaped cold-formed thin-walled stee...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a light steel structure and its construction method in which the truss composite beam is connected to the upper and lower floors, and the connection between the floor beam and the upper and lower wall load-bearing trusses is not firm, and the local pressure of the floor beam is difficult to meet. The problem of stress requirements; it is also necessary to solve the problem that the floor beams, connecting pipes and floor slabs are prone to vibration and deformation; it is also necessary to solve the technical problems that the gusset plate is prone to damage first, the integrity of the components is poor, and the construction process is complicated; It is also necessary to solve the technical problems that the existing wall sheet columns are not firmly connected to the foundation, the form and structure of the column feet used for connection with the foundation are complicated, intensive production cannot be carried out, production efficiency is low, and on-site safety accidents are likely to be caused
