Embodiment 1

[0023] as attached figure 1 As shown in , the sound insulation floor of the present invention is composed of a reinforced concrete structure floor 1, a sound insulation leveling layer 2, a bonding layer 3 and a surface layer material 4, which are sequentially stacked from bottom to top. The base layer is a reinforced concrete structure floor 1, and the middle layer is The sound insulation leveling layer 2, the upper layer is an adhesive layer 3 and a surface material 4, and the adhesive layer 3 is located between the sound insulation leveling layer 2 and the surface material 4.

[0024] In this embodiment, the sound insulation leveling adhesive material used for the sound insulation leveling layer of the integral sound insulation floor is cement-based polymer dry powder material. The cement-based polymer dry powder material includes raw materials in parts by weight: 60 parts of cement, 25 parts of vibration-damping and sound-insulating components, 4 parts of sound-absorbing an...

Embodiment 2

[0042] The difference from Example 1 is that the sound insulation leveling adhesive material used in the sound insulation leveling layer of the integral sound insulation floor is a gypsum-based polymer dry powder material. The gypsum-based polymer dry powder material includes raw materials in parts by weight: 68 parts of building gypsum, 20 parts of vibration-damping and sound-insulating components, 3.5 parts of sound-absorbing and sound-insulating components, 0.4 parts of stress-dispersing components, and 7 parts of reinforcing components. 0.6 part of tackifier, 0.3 part of water-retaining additive, and 0.2 part of water-resistant additive.

[0043] Building gypsum is a building gypsum produced from mineral gypsum.

[0044] The vibration and sound insulation components are rubber particles with a particle size of 2 mm.

[0045] The sound-absorbing and sound-insulating components are expanded vitrified microbeads with a particle size of 2mm.

Abstract

The invention discloses a whole sound insulation floor. The floor is sequentially composed of a reinforced concrete structure floor body, a sound-insulating leveling layer, a bonding layer and a surface layer material in a stacked mode from bottom to top. The reinforced concrete structure floor body serves as a base layer. The sound-insulating leveling layer serves as a middle layer. The surface layer material and the bonding layer serve as an upper layer. The bonding layer is located between the sound-insulating leveling layer and the surface layer material. The invention further discloses a construction method for the whole sound insulation floor. Floorboards can be directly laid on the whole sound insulation floor according to a common decoration method, the clear height of a residence will not be reduced, and loads of a floor structure will not be increased.

Description

technical field [0001] The invention belongs to the technical field of building materials and construction, and in particular relates to an integral sound-insulating floor slab and a construction method thereof. Background technique [0002] The sound insulation cushion materials of the traditional floating sound insulation floor system are mostly low-strength materials, such as cross-linked polyethylene rubber pads, extruded polystyrene boards, rock wool boards, etc., which do not have bearing capacity, and the sound insulation cushion materials are different from There is no effective bonding between floor and surface materials, so 40-50mm reinforced concrete or reinforced fine stone concrete should be made on the cushion (Note: 40mm reinforced layer is the minimum requirement for this type of floating floor at home and abroad) , The total thickness of the sound insulation layer structure generally reaches 60~70mm, which significantly reduces the effective floor height of ...
