Prefabricated bottom plate with removable ribs and production method of laminated plate

Abstract

The invention relates to a prefabricated bottom plate with removable ribs and a production method of a laminated slab. The prefabricated bottom plate comprises a concrete slab and at least two removable ribs fixed on the concrete slab, each removable rib comprises a square steel pipe filled with high-strength mortar, an embedded part and a fixing part, the square steel pipe is arranged on the surface of the concrete slab, the embedded part is anchored in the concrete slab, and the fixing part penetrates through the square steel pipe and is connected with the embedded part; and a reinforcing mesh is pre-buried in the concrete slab. The laminated slab comprises the prefabricated bottom plate and a cast-in-place layer. The production method of the laminated slab comprises the steps that S1, a side mold is arranged; S2, a reinforcing mesh and removable ribs are placed; S3, concrete is poured; S4, the prefabricated bottom plate is transported and positioned; and S5, dismantling is conducted. The prefabricated bottom plate is provided with the removable ribs, it can be effectively guaranteed that the concrete slab cannot crack or deform due to insufficient rigidity in the demolding, hoisting and transporting stages, and the prefabricated bottom plate can be detached and reused in the later stage. The production method of the laminated slab is simple in step and high in construction efficiency.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, in particular to a production method of a prefabricated base plate with removable ribs and a laminated plate. Background technique [0002] The laminated floor is the most widely used prefabricated component in prefabricated buildings. The laminated floor has the advantages of high production efficiency, green environmental protection, and short construction period. However, the commonly used truss-reinforced laminated slabs have problems such as high steel bar content, large slab thickness, many on-site installation supports, and difficulty in supporting formwork with two-way slab post-cast belts. Due to the above reasons, its overall cost is much higher than that of cast-in-place slabs. [0003] The steel content of the laminated floor slab is much larger than that of the traditional cast-in-place slab. The reason is that the rigidity of the prefabricated floor is small, and tru...

Problems solved by technology

There are many problems with this method: truss reinforcement is still required and cannot be disassembled. In addition, the UHPC ultra-high performance concrete used is high in cost, unfavorable for promotion, and difficult to produce
