Description

TECHNICAL FIELD

[0001] The present application belongs to the field of building technology, and particularly relates to a concrete composite slab structure for building with firm connection. BACKGROUND

[0002] The concrete composite slab is a kind of assembled monolithic structure composed of a prefabricated prestressed concrete bottom plate (or a prefabricated bottom plate) and a cast-in-situ concrete layer (or a cast-in-situ slab), and has good integrity and seismic resistance. The concrete composite slab saves the formwork in construction, accelerates the construction progress, and thus reduces the engineering cost. At present, the process for manufacturing the concrete composite slab at the construction site is as follows: the prefabricated bottom plate is laid at the construction site, and the cast-in-situ concrete is poured on the prefabricated bottom plate. The cast-in-situ concrete is solidified to form the cast-in-situ slab, thereby forming the prefabricated concrete composite slab.

[0003] Generally, in order to increase the stability of the composite slab, the steel bars are usually laid on the prefabricated bottom plate, and then the concrete is poured, so that the whole composite slab has good overall structural stability after being formed and is not easy to be broken during the hanging process.

[0004] However, the existing technology usually places the triangular steel bars on the prefabricated bottom plate, and then places the steel bars in the triangular steel bars. This structure is easy to cause displacement of the steel bars during pouring of the concrete, and the steel bars are generally located at the bottom, and the stability of the top is poor compared with the bottom. Meanwhile, using the existing traditional method, the arrangement density of the steel bars cannot be controlled according to the use of different walls, so as to control the overall stability of the steel composite slab.
