A steel structure residential floor slab with fireproof function

Abstract

The invention discloses a floor slab for a steel structure residence with a fireproof function, which belongs to the field of floor slabs. A floor slab for a steel structure residence with a fireproof function includes a main floor slab, the upper and lower ends of the main floor slab are connected with grid plates, and the grid The end face of the slab far away from the main floor is connected with a mixed layer. There are multiple fire extinguishing units densely distributed in the grid slab. The mixed layer includes a reinforced steel plate and a concrete layer. Corresponding through holes, the through holes on the reinforcing steel plate are fixedly connected with reinforcements. When the surface of the indoor floor is threatened by open fire, the temperature of the floor will rise, and the grid plate will be heated rapidly and conduct the heat to the fire extinguishing unit. The fire extinguishing gas in the grid expands and escapes when heated, and sprays out of the floor along the through holes and reinforcements on the reinforcing steel plate. The fire extinguishing gas in multiple grids can work together to extinguish nearby open flames.

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...

AI Technical Summary

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
