Concrete prefabricated board, connection structure and construction method thereof

Abstract

The invention relates to the field of prefabricated buildings, and provides a concrete prefabricated board, a connection structure and a construction method thereof. In particular, the concrete prefabricated board is provided and includes a prefabricated board body and board bottom reinforcing steel bars, and the top surface of the prefabricated board body is a floor board structure finished surface. At least parts of the edges of the prefabricated board body are provided with grooves for placing connection reinforcing steel bars, and the grooves extend from the edges where the grooves are located to the inner sides of the edges. The connection structure of the concrete prefabricated board and the construction method of the connection structure are also provided. The prefabricated concreteboard and a board support are arranged in place; the connection reinforcing steel bars are placed in the grooves in the both sides of the board support, and at least parts of the connection reinforcing steel bars extend out to an area where the top surface of the board support is located; and concrete is at least poured to the grooves and the top surface of the board support.

Description

technical field [0001] The present disclosure relates to the field of prefabricated buildings, in particular to a concrete prefabricated panel, a connection structure and a construction method thereof. Background technique [0002] Prefabricated buildings refer to buildings assembled on site using prefabricated components. The advantage of this kind of building is that it can be constructed quickly, is less restricted by climatic conditions, saves labor and can improve the quality of construction. At present, in the assembly of integral concrete structures, reinforced concrete laminated floors are generally used. The method is to set truss steel bars in the precast concrete floor slabs. The surface is not the final finished surface of the structural floor, but the truss reinforcement is exposed, and the truss reinforcement is covered when the concrete laminated layer is poured on site, so that it becomes an integral concrete structure and bears the load together.

AI Technical Summary

Problems solved by technology

[0003] The cast-in-place laminated layer on the precast concrete floor needs to pour a large amount of concrete on site, and there are many wet operations, and it takes a certain time for the concrete of the laminated layer to solidify, and the support of the prefabricated wall and other components needs to be fixed on the floor. This process must It can only be carried out after the concrete of the laminated layer is solidified, resulting in low construction efficiency

[0004] Usually, the side of the concrete prefabricated slab needs to protrude from the side of the steel bar (beard bar) to realize the connection with the adjacent plate or slab support, and the existence of the beard bar greatly reduces the efficiency of the industrial production of the concrete precast slab, and different projects, The spacing required for the beard bars of different panels is not the same, resulting in a low reuse rate of side forms for making concrete precast panels
