The invention discloses a fireproof steel structure for a building, and relates to the technical field of steel structures, the fireproof steel structure comprises a frame assembly, the frame assembly forms a main body structure of the steel structure, and the frame assembly comprises a top frame, a reinforcing cross beam, two vertical beams and two bottom supporting frames; cavities are formed in the top frame, the reinforcing cross beam, the two vertical beams and the two bottom supporting frames, the reinforcing cross beam is fixedly communicated with the top frame, the two vertical beams are fixedly communicated with the top frame, and the two bottom supporting frames are fixedly communicated with the vertical beams; the built-in water pipe made of PP plastic is utilized, when a fire occurs, the temperature in the frame assembly can be rapidly increased under the heat conduction effect of metal, and therefore the built-in water pipe can preliminarily absorb heat, and when the temperature is further increased, the built-in water pipe can be melted and broken under the high-temperature effect; and water in the built-in water pipe can flow into the cavity, so that the water forms water vapor to absorb a large amount of heat, and the fireproof effect is achieved.
本发明公开了一种建筑用防火钢结构，涉及钢结构技术领域，包括框架组件，所述框架组件构成该钢结构的主体结构，所述框架组件包括顶框架、加强横梁、两个竖梁以及两个底撑架，所述顶框架、加强横梁、两个竖梁以及两个底撑架的内部均开设有空腔，所述加强横梁与顶框架固定连通，且两个竖梁与顶框架固定连通，两个所述底撑架与竖梁固定连通；本发明利用PP塑料制成的内置水管，在发生火情时，框架组件内部的温度会在金属的导热作用下快速升高，从而内置水管能够初步吸收热量，而当温度进一步升高时，内置水管会在高温作用下发生熔化、破裂，使得内置水管中的水液能够流入空腔中，从而水液形成水蒸气吸收大量的热量，进而起到防火作用。
