AI Technical Summary
The existing prefabricated houses have poor safety performance in fires and lack effective fire-proof structures.
A prefabricated cement fireproof room with a fire-proof structure is designed, using prefabricated base, prefabricated wall, prefabricated roof, water pipes and fire sprinklers. The prefabricated wall is equipped with permeable grooves, diversion grooves and drainage grooves. The roof is equipped with heat dissipation grooves and exhaust holes. Water pipes and fire sprinklers are used to spray water to cool down and block fire.
When a fire occurs, the fire sprinkler nozzle in the permeable tank sprays water to form a water curtain to block the fire. Through the design of the diversion trough and drainage trough, the water flows along the inside of the wall to cool down and prevent the fire from spreading. At the same time, water evaporates heat to absorb, reduces the indoor temperature, and steam is discharged through the heat dissipation tank and exhaust holes to achieve heat dissipation outside the house.
