At present, modern commercial and residential buildings require light weight, so the structure is getting thinner and thinner. Generally, the thickness of the floor slab is 100-150mm; the floor structure layer is mostly composed of reinforced concrete, and then a layer of cement mortar is laid during decoration and then ceramic tiles are installed. The sound insulation effect of this kind of floor structure is much less than the requirements of "7.1 Noise and Sound Insulation" in "Code for Residential Buildings" GB503682005. Therefore, the problem often encountered is: due to the poor sound insulation effect of the floor, day or night , especially in the dead of night at night, the movement of people upstairs or the play of children will disturb the neighbors downstairs. In order to solve the problem of sound insulation, there is also a method of installing a sound insulation ceiling in the house, but this sound insulation method has a complex structure and is inconvenient to construct. , takes up more floor space.

Further, the thickness of the phenolic foam board is 10-15mm, and the joints between the adjacent phenolic foam boards are connected with waterproof tapes.

The waterproof layer is made of glass fiber board, the thickness of the glass fiber board is 5-8mm, and the joints between the adjacent glass fiber boards are connected with waterproof tapes.

Skirts are adhered around the wall, and a building sealant is arranged between the lower end of the skirting and the floor.

The thickness of the flame-retardant sound insulation felt layer is 4-6 mm.

Compared with the prior art, the beneficial effects of the present utility model are:

Phenolic foam board has dense cells and has high thermal insulation and sound insulation performance. It has been widely used in wall panels for thermal insulation and sound insulation of home decoration, but its water and moisture resistance is insufficient, so it cannot be used in floor floors. In this scheme, the The phenolic foam board is arranged between the damping pad and the waterproof layer (glass fiber board) to prevent the phenolic foam board from being damaged by moisture and improve the thermal insulation effect of the floor, and the floor has a damping effect by setting the damping pad;

The "L"-shaped sound insulation board improves the sound insulation performance around the floor and reduces the formation of surrounding sound bridges. With the plastic film on the upper side, it aims to improve the waterproof and moisture-proof effect of this layer, and reduce the thermal insulation of the lower layer during the construction of the fine stone concrete layer. In addition, through the cooperation of the flame retardant sound insulation felt layer and the "L" type sound insulation board, the sound insulation effect of the entire floor is improved.
