A prefabricated building composite panel

Abstract

The invention relates to a prefabricated building laminated slab. The prefabricated building laminated slab comprises rectangular laminated slab bodies and pouring slabs poured on the laminated slab bodies, wherein a plurality of reinforcing steel bars which are criss-crossed in the horizontal direction are arranged on the upper surfaces of the laminated slab bodies; the laminated slab bodies comprise a plurality of reinforcing steel channels fixedly connected with the reinforcing steel bars, the reinforcing steel channels are close to the end faces of the laminated slab bodies in the horizontal direction correspondingly, and the reinforcing steel bars penetrate through the reinforcing steel channels and stretch out of the laminated slab bodies; and a plurality of inserting holes allowingthe reinforcing steel bars to be inserted are formed in the reinforcing steel channels, and movable steel channels used for fixing the reinforcing steel bars inserted along the inserting holes are slidably arranged on the upper surfaces of the laminated slab bodies. The prefabricated building laminated slab has the effects that the gap between the two laminated slab bodies is reduced, the tractionforce borne by the laminated slab bodies is balanced, operation is convenient, the structural strength of the laminated slab bodies is not prone to be damaged, and the alignment process between everytwo adjacent laminated slabs is convenient.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a prefabricated building composite board. Background technique [0002] At present, prefabricated buildings have the advantages of short construction period and low cost, but due to the heavy weight of prefabricated components, it is difficult to hoist and assemble between components. The prefabricated building laminate structure helps to solve this problem. [0003] This structure divides the thickness of the floor slab into two parts: factory prefabrication and on-site pouring, which can not only reduce the weight of components during transportation and installation, but also eliminate the use of formwork and formwork on site, thereby improving work efficiency and ensuring construction safety; Through secondary pouring on site, the bearing capacity of the laminated slab is improved and the overall rigidity of the building is strengthened. [0004] The splicing t...

Problems solved by technology

[0006] In view of the above-mentioned related technologies, the inventor believes that when connecting through the threaded head or the elbow used for anchoring at both ends of the above-mentioned prefabricated reinforcement, there is a large gap at the connection, and splicing errors are prone to occur when filling the gap, so that the two laminated plates The two thread heads need to be precisely aligned when connecting, and the operation is more complicated
