Description
Technical Field
The invention relates to the field of floor slabs, in particular to a floor slab with a fireproof function for a steel structure house.
Background
Floor generally refers to a concrete precast element produced by processing in a precast yard. The bearing part in the floor layer divides the house into a plurality of layers in the vertical direction and transmits the vertical load of people, furniture and the like and the self weight of the floor to the foundation through the wall body, the beam or the column. The floor can be divided into a plurality of forms such as a wood floor, a brick arch floor, a reinforced concrete floor, a steel lining bearing floor and the like according to the used materials. The floor is divided into wood floor, brick arch floor, reinforced concrete floor and steel lining floor according to the different materials. The reinforced concrete floor and the steel lining plate floor are collectively called steel structure floor.
The reinforced concrete floor is made of concrete and reinforcing steel bars. The floor slab is firm, durable, high in rigidity, high in strength and good in fireproof performance, and is generally applied at present. According to the construction method, the prefabricated reinforced concrete floor slab can be divided into a cast-in-place reinforced concrete floor slab and a fabricated reinforced concrete floor slab.
Cast-in-place reinforced concrete floor slabs are generally solid slabs, and the cast-in-place floor slabs are often cast together with cast-in-place beams to form cast-in-place beam slabs. Common types of cast-in-place beam slabs include ribbed slabs, cross beam slabs, girderless slabs and the like.
The assembled reinforced concrete floor slab is mainly made of round hole plates and groove-shaped plates (divided into a positive groove shape and a negative groove shape) except for few solid plates. The assembled reinforced concrete floor slab generally has reinforcing steel bars extending from the slab ends, and the joints are filled with concrete after the floor slab is assembled on site to strengthen the integrity,
the steel lining plate floor is an integral floor formed by pouring the profiled steel sheet and concrete, the profiled steel sheet plays a role of a template for casting the concrete in situ at the lower part, and simultaneously, the profiled steel sheet can work together with the concrete due to the addition of ribs or extrusion of grooves, so that the reinforcement effect is played. The steel lining plate floor slab is used in large space building and high building, and has raised construction speed, great rigidity and high integrity. And the intercostal space of the profiled steel sheet can be used for laying electric power or communication pipelines.
The existing floor slab for the fireproof steel structure house cannot play a role in extinguishing fire because a flame-retardant coating material is coated on the surface of the floor slab or a flame retardant is doped in a floor slab manufacturing material, electric wires are generally buried inside the floor slab and hidden in order to meet the requirement of attractiveness in a house building, and once the electric wires are accidentally ignited, particularly when the roof slab in an indoor building meets the threat of open fire, a resident cannot quickly extinguish the fire.
