Problems solved by technology
[0007] Existing floor slabs with fire-resistant steel structures are generally coated with flame-retardant coating materials on the surface of the floor slabs, or mixed with flame retardants in the floor slab materials. For aesthetic requirements, wires are generally buried inside the floor to hide them. Once these wires accidentally catch fire, especially when the roof of an indoor building encounters the threat of open flames, it is difficult for residents to quickly extinguish the fire

The invention discloses a floorslab with a fireproof structure for a steel structure house, and belongs to the field of floorslabs. The floorslab with the fireproof structure for the steel structure house comprises a main floorslab, wherein grid plates are connected to the upper end and the lower end of the main floorslab; mixed layers are connected to one end surfaces, far away from the main floorslab, of the grid plates; multiple fire extinguishing units are densely distributed in the grid plates; the mixed layers comprise reinforced steel plates and concrete layers; through holes corresponding to grids of the grid plates are dug in the reinforced steel plates and the concrete layers; and reinforcing pieces are fixedly connected to the through holes in the reinforced steel plates. When the surface of the indoor floorslab is threatened by the open fire, the temperature of the floorslab rises, the grid plates are heated quickly so as to conduct heat onto the fire extinguishing units, fire extinguishing gases in the fire extinguishing units are heated so as to be expanded, escaped and sprayed out of the floorslab along the through holes and the reinforcing pieces on the reinforced steel plates, and the fire extinguishing gases in the multiple grids jointly act to achieve an effect on extinguishing the nearby open fire.
Description
technical field [0001] The invention relates to the field of floor slabs, and more specifically relates to a steel structure residential floor slab with a fireproof function. Background technique [0002] Floor slab generally refers to a concrete prefabricated part processed and produced by the prefabrication yard. The load-bearing part of the floor layer divides the house into several floors in the vertical direction, and transmits the vertical loads such as people and furniture and the self-weight of the floor to the foundation through walls, beams or columns. According to the materials used, it can be divided into several forms such as wooden floor, brick arch floor, reinforced concrete floor and steel lining load-bearing floor. According to the different materials used, it can be divided into wooden floor, brick arch floor, reinforced concrete floor and steel lining floor. Reinforced concrete floors and steel lining floors are collectively referred to as steel structur...
