AI Technical Summary

Technical Problem

The concrete laminated plate needs to be equipped with a large number of temporary support parts during the construction phase, resulting in low construction efficiency and no significant improvement compared with the cast-in-place construction process.

Method used

By providing fitting teeth on the sides of the prefabricated plate, adjacent prefabricated plates are connected through mutual engagement of fitting teeth, reducing the number of temporary support members, and anchoring each other through truss reinforcement bars and concrete superimposed layers to enhance the connection strength.

Benefits of technology

The number of temporary support parts and construction hours are reduced, the construction efficiency is improved, and the assembly connection strength of prefabricated plates is improved.

Abstract

The invention discloses a construction method of a tooth-shaped closely-spliced joint concrete composite floor slab, the composite floor slab comprises prefabricated slabs, the side faces of the prefabricated slabs are provided with embedded teeth, every two adjacent prefabricated slabs can be connected through mutual engagement of the embedded teeth, and the prefabricated slabs are provided with truss steel bars extending out in the thickness direction of the prefabricated slabs. By arranging the embedded teeth on the side faces of the prefabricated slabs, the connecting strength of the spliced prefabricated slabs can be improved, so that the number of needed temporary supporting pieces is reduced, the construction time of the supporting pieces is shortened, and the construction efficiency is improved. The invention relates to the field of fabricated buildings in civil engineering.
