Description

Technical Field

[0001] This utility model belongs to the field of floor structure technology, specifically a thermal insulation and soundproof floor structure based on microporous damping elastomer. Background Technology

[0002] Floor slabs are horizontal load-bearing components that separate floor spaces in a building. Their core functions include bearing loads, transmitting forces, supporting walls, and providing sound and thermal insulation. With social development, the number of high-rise buildings is increasing, and people's requirements for sound and thermal insulation between floors are also getting higher and higher. In particular, the impact sound generated by people on the ground during activities can easily be transmitted downwards through floor slabs and walls. In addition, it is necessary to avoid excessively low or high floor surface temperatures, reduce discomfort caused by radiant heat exchange, and improve the comfort of living. Therefore, it is necessary to improve the thermal and sound insulation effects of floor slab structures.

[0003] Existing thermal insulation and soundproof floor slab structures have certain drawbacks in use. These structures typically employ organic and polyurethane insulation materials as the insulation and soundproofing layer laid directly on the floor base. However, polyurethane materials lose elasticity at low temperatures and experience accelerated creep at high temperatures, leading to a decline in sound insulation and thermal insulation performance. While organic insulation materials have low thermal conductivity, their combustion performance is only B1, requiring an additional A-grade protective layer for thickening. This further reduces the thermal insulation and soundproofing effect of the floor slab structure, failing to meet people's needs. Utility Model Content

[0007] As a further embodiment of this utility model: the reinforcing protective layer is configured as a mesh structure woven or welded from steel wire; the waterproof tape is placed on the upper end of the elastic thermal insulation and sound insulation layer and connected to the reinforcing protective layer. The waterproof tape prevents water penetration and plays a waterproof sealing role, protecting the floor structure from water erosion. The reinforcing protective layer can enhance the structural strength and integrity of the floor, prevent cracks and deformation of the floor, and improve the impact resistance and crack resistance of the floor.

[0008] As a further embodiment of this utility model: the protective layer is formed by pouring concrete prepared with fine stone; the upper surface of the protective layer is leveled; the protective layer has good density and strength, which can protect the underlying thermal insulation and sound insulation layer and steel wire mesh and other structures, while providing a flat and solid foundation for the finishing layer.
