Problems solved by technology

[0003] Steel is a very good material, easy to forge and shape, and has high strength after forming. However, after the steel structure and concrete are used to complete the building, if a fire occurs, the flame and high temperature will continue to heat the concrete and steel structure, and then The steel structure is no longer stable, so that the buildings supported by the steel structure will collapse, which will cause more serious safety problems and economic losses

Abstract

The invention discloses a fireproof building steel structure. The fireproof building steel structure comprises two layers of floor slabs which are symmetrically arranged, the two layers of floor slabs are connected through a plurality of supporting steel columns which are arranged at equal intervals, a concrete wall body is jointly arranged on the supporting steel columns, and protection devices are arranged on the supporting steel columns, protection devices comprise notches formed in the two opposite side walls of the supporting steel columns, fixing layers are fixedly connected between the two opposite inner walls of the two notches, the fixing layers are made of carbon fiber reinforced matrix composites, the two fixing layers are arranged away from each other, and auxiliary blocks are fixedly connected between the related opposite inner walls of the two notches. According to the fireproof building steel structure, heat of the supporting steel columns and the concrete wall body can be absorbed by means of evaporation of water in a fire-fighting water pipe and melting of the auxiliary blocks and the like, the structural integrity of the supporting steel columns is guaranteed by means of the fixing layers, and then the structure of a device can be kept stable in a fire disaster.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a fireproof building steel structure. Background technique [0002] Clothing, food, housing and transportation are a very important part of human life. In order to meet people's various needs for housing, many kinds of buildings have been designed and constructed. In modern times, in order to facilitate construction and ensure the stability of buildings, concrete is often used for construction. For this purpose, the corresponding steel structure is needed as a support. [0003] Steel is a very good material. It is easy to forge and shape, and has high strength after forming. However, after the steel structure and concrete are used to complete the building, if a fire occurs, the flame and high temperature will continue to heat the concrete and steel structure, and then The steel structure is no longer stable, so that the buildings supported by the steel structure wi...
