It can be processed and formed in batches in a prefabrication yard, and then transported to the construction site for direct assembly and use. It is widely used in building construction because of its convenient construction and high overall structural strength. The currently common thermal insulation composite slabs are mainly composed of two parts: a concrete pouring layer and a thermal insulation material covering the bottom of the concrete pouring layer. The concrete pouring layer plays a supporting and assembly role, and the thermal insulation material plays a role in sound insulation and noise reduction. For example, a noise-reducing and thermal insulation composite slab with application number CN202220505650.1 includes a concrete base, and a number of ribs are symmetrically fixedly connected to the front and back of the top surface of the concrete base. The ribs are arranged in a triangular shape, and the top of the ribs on the same side are fixedly connected to the same connecting rib. The above common types of composite slabs have the following problems in application:

[0003] Due to the large overall mass of the composite floor slab, it needs to work with a crane during transportation and assembly. The concrete of the composite slab is directly exposed, and the edges are easily bumped and broken during transportation, assembly and lifting, which affects the quality of the composite slab. At the same time, the concrete and the thermal insulation and noise reduction materials are clearly separated, and the overall noise reduction and thermal insulation effect is poor.

[0006] Preferably, the noise reduction and heat preservation component includes a polyurethane foam material filling layer and an asbestos base plate fixedly arranged at the bottom of the polyurethane foam material filling layer; the heat insulation and noise reduction effects are remarkable.

[0007] Preferably, a plurality of I-shaped reinforcement pieces are fixedly provided at the bottom of the partition plate, and the I-shaped reinforcement pieces are fixedly provided inside the polyurethane foam material filling layer; the strength of the polyurethane foam material filling layer can be improved, and the layer is not easily damaged.

[0008] Preferably, the upper surface of the polyurethane foam material filling layer is fixedly arranged on the partition plate, so that the composite plate can be locally insulated and heat-preserved as well as have the effect of reducing noise.

[0009] Preferably, the assembled rib assembly includes connecting transverse ribs and multiple reinforcing ribs fixedly arranged in the middle of the connecting transverse ribs, and the bottoms of the multiple reinforcing ribs are fixedly provided with snap-fit ​​ribs, which are snap-fitted onto the longitudinal stress reinforcement bars, so as to facilitate the lifting of the composite slab and the tightness of the subsequent pouring connection.

[0010] Preferably, the surface of the concrete pouring layer is coated with a waterproof coating, which can improve the anti-seepage effect of the composite board.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: a metal sealing frame is added to the edge of the composite floor, and the concrete material is directly poured in the metal sealing frame, which can not only improve the overall structural strength of the composite floor, but also reduce the problem of edge damage of the composite floor caused by transportation, lifting and assembly.
