Assembled floor cover

Abstract

A combined floor of building consists of several spaced bearing beams and composite plates. The composite plates include acoustic and thermal insulating parts with grooves on their top between the bearing beams, corrugated concrete cast in site and laid on them, fireproof and break resistant layers below the said acoustic and thermal insulating parts orderly. The floor can be cast with bearing beams uniformly in site reduce beam height so as to increase net height of room and acoustic and thermal insulating abilities, to enlarge effective space in use, to reduce sum of sub-beams and fireproof area of steel beams, with longer span length, no need of pressed steel plates and hanging roof so as to reduce cost with quality and high speed.

Description

technical field [0001] The invention relates to a beam-slab structure of a building, in particular to a composite floor. Background technique [0002] In the cast-in-place reinforced concrete frame structure system, the cast-in-place reinforced concrete beams and slabs are directly used to form the composite floor, which is economical, practical, safe and reliable, but the disadvantage is that the sound insulation performance is poor, and a ceramsite concrete layer needs to be laid on the floor to achieve Due to the requirement of sound insulation, the floor slab is heavier and thicker, the supporting formwork is more complicated, the cross-section of the frame beam is larger, the indoor space is occupied, and the construction speed is slow. In the steel structure system, the most commonly used is the cast-in-place concrete composite floor structure on the profiled steel plate. The composite beam is formed by the studs and the load-bearing beams. The beams and slabs are join...

[0002] In the cast-in-place reinforced concrete frame structure system, the cast-in-place reinforced concrete beams and slabs are directly used to form the composite floor, which is economical, practical, safe and reliable, but the disadvantage is that the sound insulation performance is poor, and a ceramsite concrete layer needs to be laid on the floor to achieve Sound insulation requirements, so the floor is heavier and thicker, the formwork is more complicated, the frame beam section is larger, the indoor space is occupied, and the construction speed is slow

In the steel structure system, the most commonly used is the cast-in-place concrete composite floor structure on the profiled steel plate. The composite beam is formed by the studs and the load-bearing beams. The beams and slabs are jointly stressed to form an integral composite floor. Faster, better overall rigidity, and lighter floors, but the disadvantage is that the sound insulation is poor and the beam height is wasted, so the net floor height is reduced, and studs, profiled steel plates and suspended ceilings are required. The steel beam has a large fire protection area and more secondary beams , increase the amount of steel used, the construction cost is higher, and the construction cost is higher
