Problems solved by technology

[0002] The commonly used reinforced concrete hollow prefabricated component slabs are long strips with a through hole in the middle. This kind of hollow prefabricated component slab has the advantages of low cost, convenient construction, and easy production. However, the assembled floor slab of this hollow prefabricated component slab has the following disadvantages : When assembling floor slabs longitudinally, a certain length is required to place the hollow prefabricated component panels on the support to meet the requirement of the shelving length. The width of the joints is small, the concrete at the joints is easy to crack, the crack resistance and leakage resistance are poor, the connection force at the joints is weak, and the length of the longitudinal lap steel bars of the two hollow prefabricated component plates does not meet the requirements, and the integrity is poor; The slot width is small, which also affects the layout of the pipeline

Abstract

A prefabricated hollow reinforced concrete slab features that its both ends have the extended platforms at the bottom and the extended reinforcing bars for butt connection of two said slabs by welding and pouring concrete. Its advantages are high connection strength and high integrity.

Description

Technical field: [0001] The invention relates to the field of building construction, in particular to a reinforced concrete hollow prefabricated component plate. Background technique: [0002] The commonly used reinforced concrete hollow prefabricated component slabs are long strips with a through hole in the middle. This kind of hollow prefabricated component slab has the advantages of low cost, convenient construction, and easy production. However, the assembled floor slab of this hollow prefabricated component slab has the following disadvantages : When assembling floor slabs longitudinally, a certain length is required to place the hollow prefabricated component panels on the support to meet the requirement of the shelving length. The width of the joints is small, the concrete at the joints is easy to crack, the crack resistance and leakage resistance are poor, the connection force at the joints is weak, and the length of the longitudinal lap steel bars of the two hollow...
