This creation is related to composite materials, especially a composite material that is used in construction and has a sound insulation effect.

In order to improve the quality of living, the problem of impact sound and noise from the floor slabs of collective residential buildings has always been a problem to be solved. The current known method is to arrange a rubber sound insulation layer on the household floor slab. The sound insulation layer is arranged on the cement layer, and then a thick cement mortar layer is laid on the sound insulation layer, and then a surface decoration material is pasted on the uppermost layer. The floor slab has a sound insulation effect, but the floor slab set by this conventional construction method is insufficient in seismic strength, and the rubber sound insulation layer and the cement mortar layer above it are more likely to have poor fastness, resulting in the risk of cracking or staying on the surface decoration material. Therefore, there are a variety of more complete sound insulation layer structures on the market, such as laying a metal rib layer, a plastic layer, cushion blocks, etc. between the sound insulation layer and the cement layer.

The applicant first explains here that the following is a detailed description of the technical content and features of the new invention based on several preferred embodiments listed in conjunction with the drawings. Those skilled in the art can understand that the invention can be applied to various types of sound insulation structures, especially It refers to the soundproof floor structure of households used in collective housing. The directional adjectives such as "top, bottom, up, down, inside, and outside" mentioned in the content of this manual are just examples of descriptive terms based on the normal direction of use. Is not intended to limit the scope of the claim. Secondly, in the following embodiments and drawings, the same element numbers represent the same or similar elements or their structural features.

As shown in Figures 1 and 2, the sound-proof composite floor 10 for construction provided by this creation is suitable for the household floor slabs of collective housing to achieve the sound insulation effect of the floor. The sound-proof composite floor of the first embodiment of this creation The floor 10 includes a plate 20 having a sound insulation bottom layer 12 and a sound insulation support layer 14. Specifically, the sound insulation bottom layer 12 has a top surface 121 and a bottom surface 122 opposed to each other, and the sound insulation support layer 14 is provided on the top surface 121. The sound insulation support layer 14 is bonded to the top surface 121 by gluing as an example. The sound insulation bottom layer 12 of the preferred embodiment is an example of a porous foam material, which can be a foam material with pores such as PU, PE, EVA, IXPE, NBR, EPDM, CR, etc., or rubber. The soundproof composite floor 10 of this creation achieves high-frequency sound absorption through the soundproof bottom layer 12, and the soundproof support layer 14 includes a plurality of plant fiber bodies 141 and a plurality of mineral bodies 142, and a glass fiber mesh (not shown in the figure) ) To enhance the strength of the plate 20 and achieve waterproofing. The sound insulation support layer 14 of the preferred embodiment is exemplified by palm board, fiberboard, etc., wherein the sound insulation support layer 14 contains materials with different structures and properties, so as to reduce the reflectivity of sound and achieve a sound insulation effect.
