The invention relates to the technical field of building steel structures, in particular to a fireproof building steel structure which comprises a steel structure body, the front cross section of the steel structure body is of an H-shaped structure, the fireproof building steel structure further comprises a coating with fireproof and waterproof functions, and the coating is smeared on the outer surface of the whole steel structure body; the steel structure comprises a steel structure body and a plurality of wrapping plate assemblies, each wrapping plate assembly comprises a first wrapping plate and two second wrapping plates, and the two second wrapping plates are arranged at H openings in the two sides of the steel structure body. The rock wool has good heat insulation performance and difficult-to-burn performance, so that the fireproof performance of the whole steel structure body is improved, meanwhile, the fireproof paint can expand to form a foam layer, and the foam layer mainly has high heat insulation performance; the composite type is used for improving the good adhesive force, durability and water resistance of the fireproof material.
本发明涉及建筑钢结构技术领域，具体是一种防火型建筑钢结构，包括钢结构本体，所述钢结构本体的正横截面为H型结构，还包括：具有防火防水功能的涂层，所述涂层涂抹在整个所述钢结构本体的外表面上；多个包裹板组件，所述包裹板组件包括一个包裹板一以及两个包裹板二，两个所述包裹板二设置在钢结构本体的两侧H口处，本发明通过设置有包裹组件以及涂料，包裹板一以及两个包裹板二的主要材质均为岩棉，而岩棉具有良好隔热的性能和难以燃烧的性能，从而提高整个钢结构本体的防火性能，同时防火漆会膨胀形成一个泡沫层，该泡沫层主要具有高隔热性能；复合型为了提高防火材料的良好附着力、耐久性和耐水性。
