The invention relates to the technical field of building steel structures, in particular to a fire-proof building steel structure. When a fire occurs, a temperature measuring device controls a water pump to start, and heat-dissipating water is transported through the water pump to a water-supply pump connecting pipe group, a heat-dissipating pipe group II, L-shaped water pipe and heat dissipation pipe group I, the water outlet from heat dissipation pipe group II and heat dissipation pipe group I cools the supporting columns and beams. All components used for fire prevention and heat dissipation are connected structures and are arranged in zones. During maintenance or fire When damage occurs and needs to be repaired or replaced, the damaged part can be easily removed for repair or replacement of new parts, thereby reducing the difficulty of repairing and replacing parts and facilitating practical use. |
