Abstract

The invention provides a fixing method of beams of a lightweight steel roof truss and the beam of the lightweight steel roof truss and a column of the lightweight steel roof truss. The fixing method of the beams of the lightweight steel roof truss and the beam of the lightweight steel roof truss and the column of the lightweight steel roof truss includes: determining contact faces of the beams and the contact faces of the beam and the column, and choosing a fixing piece to conduct fixing connection according to the contact faces. The invention further provides a fixing mechanism used for the beams of the lightweight steel roof truss and the beam of the lightweight steel roof truss and the column of the lightweight steel roof truss. The fixing mechanism used for the beams of the lightweight steel roof truss and the beam of the lightweight steel roof truss and the column of the lightweight steel roof truss comprises beams, columns, fixing beams and the fixing pieces of the columns, wherein the fixing pieces conduct fixing connection on the contact faces of the beams and the contact faces of the beams and the columns to form the fixing mechanism of fixing beams and columns. The fixing mechanism possesses functions of bending moment resistance, shearing force resistance, pressure resistance and tension resistance. The method used for the middle beam and the column of the lightweight steel roof truss improves bending moment resistance and shearing force of crossed nodes of two-way double beams and columns when the two-way double beams and the columns are fixedly connected and strengthens pressure resistance and tension of the beam in node places.

Description

technical field [0001] The invention relates to a light steel building structure and its fixing method, in particular to a fixing method for continuous beams and beams, beams and columns in a light steel roof truss, and a fixing method for strengthening the bending moment and shear force of the beam and column nodes in a light steel roof truss mechanism, the fixing mechanism simultaneously enhances the compressive and tensile properties of the beam at the nodes. Background technique [0002] The structure and construction methods of light steel roof trusses have a great influence on the quality and construction of light steel buildings. The main supporting members of light steel roof trusses, such as structural beams and structural columns, are generally composed of thin-walled steel and its products formed by cold-bending or cold-rolling thin steel plates with a thickness of 1.0-5mm. Cold-formed thin-walled steel profiles also include various types of pressed thin steel pl...
