Problems solved by technology

[0002] At present, the traditional laminated slabs in building floors are mostly solid structures, heavy and increase the static load of the floor. If they are made too thin, they are difficult to transport and have a high rate of component damage.
The existing prefabricated hollow-core slabs are light in weight and easy to construct, but because the horizontal reinforcement cannot be arranged, there is no reinforcement connection in the horizontal direction of the slab, the seismic performance is poor, and the slabs are prone to cracks

Abstract

The invention provides a hollow composite floor slab and a construction method of the hollow composite floor slab. The hollow composite floor slab is convenient to transport, low in breakage rate, small in self-weight, low in cost, large in rigidity and good in anti-seismic property. To achieve the aim, according to the scheme, the hollow composite floor slab comprises a prefabricated hollow slab body and a rear pouring reinforced concrete layer, and the prefabricated hollow slab body comprises a base board reinforced concrete layer and a porous concrete layer; a plurality of long through holes are longitudinally formed in the porous concrete layer at intervals; the two sides or the single side of the porous concrete layer are concaved in the two side faces of the base plate reinforced concrete layer, and a rear pouring portion is formed on the prefabricated hollow slab body; the rear pouring reinforced concrete layer is arranged above the prefabricated hollow slab body, and the porous concrete layer and the rear pouring reinforced concrete layer are meshed through a groove and beads. The construction method comprises the steps of manufacturing the prefabricated hollow slab body and mounting the hollow composite floor slab.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to a hollow laminated floor slab and a construction method thereof. Background technique [0002] At present, the traditional laminated slabs in building floors are mostly solid structures, which are heavy and increase the static load of the floor. If they are made too thin, they are difficult to transport and have a high rate of component damage. The existing prefabricated hollow-core slabs are light in weight and easy to construct, but because the horizontal steel bars cannot be arranged, there is no steel bar connection in the horizontal direction of the slabs, the seismic performance is poor, and the slabs are prone to cracks. Contents of the invention [0003] The object of the present invention is to provide a hollow laminated floor slab and its construction method. The hollow laminated floor slab is not only easy to transport, has low damage rate, but also h...
