Composite floor slab and construction method thereof

Abstract

The invention discloses a composite floor slab and a construction method thereof. The composite floor slab comprises a prefabricated base plate, a cast-in-place concrete composite layer, plate surface steel bars and plate bottom steel bars; lifting trusses are installed on the prefabricated base plate and connected with the prefabricated base plate through connecting nuts, and the lifting trusses can be disassembled after the prefabricated base plate is lifted to the specific location. The construction method for manufacturing the composite floor slab comprises the following steps that firstly, the prefabricated base plate on which the lifting trusses are installed is lifted to the specific location; secondly, supports are arranged on the bottom of the prefabricated base plate, and the lifting trusses are disassembled; thirdly, the plate surface steel bars are placed, the cast-in-place concrete composite layer is poured, after cast-in-place concrete reaches certain strength, the supports are disassembled, and the composite floor slab is formed. According to the composite floor slab and the construction method thereof, the component size is the same as a room, the assembly is not needed, no joint seam exists, the construction is convenient and fast, industrialization can be achieved, and the construction speed is greatly improved.

Description

Technical field: [0001] The invention designs the field of building construction, and specifically refers to a laminated floor slab and a construction method thereof. technical background: [0002] At present, some high-rise buildings use laminated floor slabs, which are convenient for construction, do not need on-site formwork, and have relatively low cost, and are convenient for lifting and transportation. The invention applies for a reinforced concrete laminated floor (application number: 201110258070.3). A reinforced concrete laminated floor is proposed, which includes a prefabricated ribbed member slab, transverse steel bars and a concrete laminated layer. The reinforced concrete laminated floor adopts a fixed channel Long connecting rods to solve the problem of misalignment of prefabricated ribbed component panels at the joints. But in fact, there are still joints in the prefabricated ribbed component slab. After the concrete laminate is poured, the bottom of the floor sla...

Problems solved by technology

But in fact, there are still joints in the prefabricated ribbed member slab. After pouring the concrete laminated layer, there may still be unevenness at the bottom of the floor slab, which will affect the appearance. In order to plaster the bottom of the slab, it is necessary to thicken the plaster layer and increase the construction cost
