Floor structure of fabricated building and building with floor structure

Abstract

The invention discloses a floor structure of a fabricated building and a building with the floor structure, and belongs to the field of fabricated buildings. The floor slab structure comprises a prefabricated layer, a cast-in-place layer and a painting layer, the cast-in-place layer is arranged on the prefabricated layer, and the painting layer is arranged on the lower side face of the prefabricated layer; the prefabricated layer is formed by closely splicing a plurality of one-way laminated slabs, and a splicing seam is formed between every two adjacent one-way laminated slabs; a metal embedded part is arranged in the one-way laminated slab, at least part of the metal embedded part is exposed out of the edge of the lower side of the one-way laminated slab and forms a connecting part, and the lower side face of the connecting part is flush with the lower side face of the one-way laminated slab; the connecting parts are used for providing a welding foundation, abutted seams between the adjacent one-way laminated slabs are eliminated in a welding mode, adhesive cement / mortar does not need to be filled in the abutted seams, the adhesive cement layers / mortar layers are prevented from deforming after being heated and affected with damp, and therefore the abutted seams of the one-way laminated slabs can keep high flatness for a long time.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, more specifically, to a floor structure of a prefabricated building and a building with the floor structure. Background technique [0002] In the field of prefabricated buildings, the laminated slab is an assembled integral floor slab composed of prefabricated floors and cast-in-place reinforced concrete layers. It is divided into one-way laminated slabs and two-way laminated slabs, which are suitable for buildings with high overall rigidity requirements. High-rise buildings and large-bay buildings. Among them, the two-way laminated slab refers to the laminated slab with connecting steel bars on the side of the slab. During construction, the connecting steel bars of two adjacent two-way laminated slabs are inserted into each other, and after the connecting steel bars are inserted on both sides, the overlapping length is not less than 10d, d is the diameter of the connecting steel...

AI Technical Summary

Problems solved by technology

[0006] Therefore, after the one-way laminated slabs in the prior art are densely assembled and poured to form a floor slab, a gap perpendicular to the slab surface is still formed on the lower side, and the thickness of the plaster layer in this gap is higher than that of other positions in the joint. After the floor is heated and damp, the degree of expansion and deformation of the plaster layer is quite different, which eventually leads to cracking and bulging at the joints of the one-way laminated boards.
