Prefabricated laminated slab and prefabrication process thereof

Abstract

The invention discloses a prefabricated laminated slab and a prefabrication process thereof, relates to a building technology, and is used for solving the problem that a common laminated slab is easyto loosen in connection. The laminated slab comprises a slab body and a connecting structure. The connecting structure comprises an embedded block arranged on the slab body, an embedded groove formedin the slab body, a connecting hole formed in the slab body, a connecting block inbuilt in the embedded block and a connecting piece used for matching with the connecting block, the embedded block andthe embedded groove of two adjacent slab bodies are embedded with each other, and the connecting piece penetrate through the connecting hole and then is in threaded connection to the connecting block. The process comprises the following process steps of: building a frame, pouring and forming, demoulding and trimming, and building and maintaining. The prefabricated laminated slab has the followingadvantages and effects that the connecting structures can be used for being connected with each other in the process that two adjacent laminated slabs are spliced with each other, so that when the laminated slabs are subjected to the action of transverse force, the laminated slabs are not prone to being separated from each other, a pouring layer poured on the laminated slabs is not prone to beingseparated, and the purpose of reducing the leakage occurrence probability is achieved.

Description

technical field [0001] The invention relates to building technology, in particular to a prefabricated laminated board and its prefabricated process. Background technique [0002] The laminated slab is an assembled integral floor slab composed of prefabricated slabs and cast-in-place reinforced concrete layers. The laminated slab has good integrity, and the upper and lower surfaces of the slab are flat, which is convenient for decoration of the facing layer. During the construction process, there is no need to build formwork. The construction period is greatly shortened compared with the method of pouring on site, so it has become a common construction method in modern engineering. [0003] At present, the Chinese invention whose authorized notification number is CN207700482U discloses a prefabricated laminated board, which includes a laminated board body, and steel bars are arranged in the laminated board body. The part of the steel bar close to the end of the laminated sla...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned prefabricated laminated slabs are first hoisted to the building when in use, and then poured with cement. The cement is used as the adhesive between two adjacent prefabricated laminated slabs. The quantity is limited, and its bonding force is not strong. When the laminated board is subjected to lateral force, it is easy to deviate. Once the laminated board deviates, the casting layer is prone to cracking, which is prone to leakage problems.
