AI Technical Summary

Technical Problem

When existing steel structure buildings are subject to severe vibration, the beams and columns will shake and extrude, affecting the safety of the building.

Method used

The prefabricated seismic steel structure is adopted, including a base, a column, a first beam and a second beam. The upper and lower ends of the column are hinged with the adjacent first beam or base, and the left and right ends of the second beam are connected to the adjacent second beam through a connecting plate, and a trapped rod is provided in the structure to improve stability.

Benefits of technology

The seismic resistance is improved through the articulated structure and the structural stability is improved through the trapped rod. Due to the use of a detachable structure, damaged parts can be replaced locally after the earthquake, reducing maintenance costs, and has the advantages of good seismic resistance, strong stability and low maintenance costs.

Abstract

The utility model discloses an assembly type anti-seismic steel structure in the field of steel structure buildings, which comprises a base, a stand column, first cross beams and second cross beams, the upper end and the lower end of the stand column are respectively hinged with the adjacent first cross beams or the base, and the left end and the right end of each second cross beam are respectively connected with the adjacent second cross beams through connecting plates. Diagonal draw bars are connected between the bases and the second cross beams which are adjacent up and down and between the second cross beams which are adjacent up and down in a diagonal mode. The assembly type anti-seismic steel structure has the advantages of being good in anti-seismic performance, high in stability, low in maintenance cost and the like.
