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.
本发明公开了一种防火建筑钢结构，包括两层呈对称设置的楼板，两层所述楼板之间通过多个呈等间距设置的支撑钢柱相连，多个所述支撑钢柱上共同设有混凝土墙体，多个所述支撑钢柱上均设有保护装置，所述保护装置包括设置在支撑钢柱两个相对侧壁上的缺口，两个所述缺口的两个相对内壁之间均固定连接有固定层，所述固定层由碳纤维增强基复合材料制成，两个所述固定层呈相互远离设置，两个所述缺口的相关相对内壁之间均固定连接有辅助块。本发明中可以借助消防水管中水的蒸发以及辅助块等熔化吸收支撑钢柱和混凝土墙体的热量，并借助固定层保证支撑钢柱的结构完整，继而使得装置可以在火灾中保持结构稳定。
