Disclosure of Invention

In order to reduce the weight of a precast floor slab and a precast module, the utility model provides the precast floor slab and the precast module, and the concrete technical scheme is as follows.

The prefabricated floor slab is characterized by comprising an upper wing plate, a transverse rib and a longitudinal rib, wherein the transverse rib and the longitudinal rib are connected to the lower surface of the upper wing plate, and the transverse rib and the longitudinal rib divide a space below the upper wing plate into a plurality of accommodating spaces; the holding space is internally provided with a heat preservation layer.

By adopting the technical scheme, the lower surface of the upper wing plate is provided with the transverse ribs and the longitudinal ribs, so that the space below the upper wing plate is divided into a plurality of accommodating spaces, and the accommodating spaces are internally provided with heat insulation layers. The heat insulation layer is generally made of foam materials, has light weight, is beneficial to improving heat insulation performance, and greatly reduces the weight of the precast floor slabs. The transverse ribs and the longitudinal ribs are also beneficial to enhancing the bearing capacity of the precast floor slabs.

Further, solid hidden beams are further arranged at two ends of the precast floor slab in the longitudinal direction, and the extending direction of the solid hidden beams is parallel to the transverse ribs. The solid hidden beams can enhance the structural strength of the bottom plate and the end portions of the bottom plate.

Further, edge sealing ribs are further arranged at two ends of the prefabricated floor slab in the transverse direction, and the extending direction of the edge sealing ribs is parallel to the longitudinal ribs. The edge sealing rib can seal the heat preservation layer of the edge in the bottom plate and the top plate.

Further, steel bars are arranged in the transverse ribs and the longitudinal ribs. The reinforcing steel bars are beneficial to enhancing the bearing capacity of the transverse ribs and the longitudinal ribs.

Further, the upper wing plate, the transverse ribs and the longitudinal ribs are integrally formed. Preferably, the upper wing plate, the transverse rib and the longitudinal rib are all made of concrete or ultra-high performance concrete.

Further, the cross sections of the transverse ribs and the longitudinal ribs are in inverted trapezoids. The transverse ribs and the longitudinal ribs which are in the shape of inverted trapezoids are more beneficial to weight reduction.

Further, the inner surface of the edge sealing rib is an inclined surface, and the width of the lower end of the edge sealing rib is smaller than that of the upper end of the edge sealing rib. The sealing rib arranged in this way can also achieve the effect of reducing weight.

Further, the lower surfaces of the transverse ribs and the longitudinal ribs are lower than the lower surfaces of the edge sealing ribs. This is advantageous for the bearing capacity of the middle part of the protruding precast floor slabs.

Based on the same inventive concept, the utility model also relates to a prefabricated module, which comprises a bottom plate, a first side plate, a top plate and a second side plate which are sequentially connected, wherein the top plate and/or the bottom plate adopts the prefabricated floor slab.
