The invention discloses a building fireproof steel structure. The building fireproof steel structure comprises a steel structure body, wherein partition plates are fixedly installed on the inner walls of the front side and the rear side of the steel structure body, water storage cavities are formed above the partition plates, rectangular holes are formed in the positions, close to the middles, of the outer walls of the tops of the partition plates, water baffles are fixedly installed on the inner walls of the rectangular holes, and water guide plates are fixedly mounted on the inner walls of the front side and the rear side of the steel structure body. According to the building fireproof steel structure, water in the water storage cavities absorbs heat on the steel structure body, the situation that the temperature of the steel structure body rapidly rises and loses the bearing capacity is prevented, after the steel structure body is continuously burnt, the temperature of the steel structure body is transmitted to the partition plate, the water baffles are heated and melted, the water in the water storage cavities flow downwards and is divided through the water guide plates, the water flows downwards along the inner wall of the steel structure body, vaporization is generated, the temperature of the steel structure body is reduced, the bearing time of the steel structure body is prolonged, and wall collapse caused by bearing capacity loss and deformation of the steel structure body after a fire disaster occurs is prevented.
本发明公开了一种建筑防火钢结构，包括钢结构本体，所述钢结构本体的前后两侧内壁固定安装有隔板，且隔板的上方形成储水腔，所述隔板的顶部外壁靠近中部开有矩形孔，且矩形孔的内壁固定安装有挡水板，所述钢结构本体的前后两侧内壁固定安装有导水板。本发明储水腔中的水吸收钢结构本体上的热量，防止钢结构本体温度快速升高，失去承载力，当钢结构本体受到持续的火烧后，钢结构本体的温度传递到隔板，使挡水板受热融化，储水腔中的水向下流出，经过导水板分流，顺着钢结构本体的内壁向下流动，发生汽化降低钢结构本体的温度，延长钢结构本体的承载时间，防止发生火灾后钢结构本体失去承载力，发生形变，导致墙体倒塌。
