Prefabricated laminated floor slab with upturning side edge for slab descending area and construction method thereof

Abstract

The invention relates to a prefabricated laminated floor slab with an upturning side edge for a slab descending area. The floor slab comprises an upper prefabricated laminated floor slab body, a lower prefabricated laminated floor slab body with the upturning side edge, a framework of steel reinforcement, an embedded nut, a split bolt, soft adhesive tape and a cast-in-situ concrete side formwork. The lower prefabricated laminated floor slab body with the upturning side edge is in sealed connection with the lower portion of the upper prefabricated laminated floor slab body through the soft adhesive tape; the embedded nut is embedded and fixed on the upturning side edge, one end of the split bolt is fixed to the embedded nut, and the other end of the split bolt is fixed to the cast-in-situ concrete side formwork. By the adoption of the prefabricated laminated floor slab with the upturning side edge for the slab descending area, the problems are solved that in a construction field, the workload of reinforcement assembling during formwork erecting is large and formwork erecting is difficult, and the work efficiency of field construction in the slab descending area is improved; the construction difficulty is greatly reduced; the integrated production of a component factory is achieved, and components are accurate in size, high in industrialization degree and guaranteed in quality; the lower prefabricated laminated floor slab body with the upturning side edge and the upper prefabricated laminated floor slab body are prefabricated separately, poured and connected on site, and the components are transported without special treatment.

Description

technical field [0001] The invention relates to a prefabricated laminated floor slab with side flanging used in a lowering slab area, and belongs to the technical field of prefabricated laminated floor slabs. Background technique [0002] With the rapid development of the construction industry, the quality standards of construction projects and the requirements for energy conservation and environmental protection are getting higher and higher. The traditional wooden formwork at the lower board of the bathroom cannot meet the requirements of energy saving, environmental protection and efficiency. How can the formwork at the lower board of the bathroom meet both requirements? The country is green, energy-saving and environmentally friendly, and it can be assembled and constructed to improve construction efficiency. Therefore, this method must have new breakthroughs and innovations. [0003] The pouring quality of the toilet lowering slab concrete directly affects the follow-up...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved in the present invention is: in the existing floor slab in the lowering slab area, there are often defects in the lowering slab hanging mold expansion, missing edges and corners, grout holes, formwork deviation, insufficient height of the lowering slab, and great difficulty in construction.
