Description

Floor structure

Technical Field

The utility model relates to a building field, concretely designs a floor structure.

Background

The traditional building production mode has the problems of high building energy consumption, high resource consumption, more engineering quality and safety problems and the like, particularly, a floor structure generally adopts a poured floor slab and a prefabricated floor slab, the integrity of the cast-in-place floor slab is good, but a template needs to be supported and poured on site, the template needs to be disassembled after the floor structure reaches a solidification period, the construction with the functions of heat preservation, sound insulation, water prevention and the like can not be carried out in the construction process, in addition, the construction period is long, the difficulty is high, the energy consumption is high, the cost is high, the prefabricated floor slab does not need to be supported on site, the construction period is short, the construction cost is low, the prefabricated component is heavy in self weight, large-scale hoisting equipment is needed in the construction engineering, cracks are easy to generate at the.

Disclosure of Invention

The utility model aims at providing a floor structure for solving above-mentioned problem, not only can save material and resource, improve engineering quality and efficiency of construction.

The purpose of the utility model is realized like this:

the utility model discloses a floor structure includes:

a floor base layer;

the floor bearing layer is arranged on the floor base layer and comprises a plurality of rectangular steel plates which are bent along the length direction to form a plurality of wave bulge structures with dovetail-shaped cross sections, two adjacent rectangular steel plates are spliced by the wave bulge structures positioned at the edges, and the cross sections of the bent parts of the wave bulge structures are arc-shaped; and a floor layer arranged on the floor bearing layer.

The thickness of the rectangular steel plate in the floor structure is 0.3-3 mm.

The floor base layer in the floor structure comprises a light steel floor beam and a fireproof structure plate arranged at the bottom of the light steel floor beam.

The gaps of the light steel floor beams in the floor structure are filled with heat insulation and/or sound insulation materials.

The floor surface layer in the floor structure comprises a carpet cushion layer laid on the floor bearing layer and a carpet laid on the carpet cushion layer.
