Embodiment 1

[0034] Lightweight sound insulation mortar is selected as follows:

[0035]

[0036] Mix evenly according to the above percentage example, add an appropriate amount of water and stir evenly in a mixer, and perform a performance index test. The test data is as follows:

[0037] Apparent density: 935kg / m 3 , Tensile bond strength: 0.29Mpa, compressive strength: 4.2Mpa, linear shrinkage: 0.03%, thermal conductivity is 0.153W / m.k.

[0038] The high-strength lightweight sound insulation mortar is selected as follows:

[0039]

[0040]

[0041] Take 30mm thick lightweight sound-proof mortar of this proportion and spread it on the reinforced concrete floor, and lay 5mm-thick high-strength lightweight sound-proof mortar on the 30-thick lightweight sound-proof mortar surface layer as a protective surface layer to improve the impact sound. Detection, weighted normalized impact sound pressure level improvement is 16dB.

[0042] Select the above-mentioned lightweight sound ins...

Abstract

The invention relates to a heat-insulating soundproof construction method for a building floor slab. The construction method comprises the following steps: paving 10-50mm thick soundproof mortar (2) on the top of a reinforced concrete floor (1) and paving 5-10mm thick high-strength soundproof mortar (3) on the surface layer of the soundproof mortar.

Description

[0001] Technical field: [0002] The invention belongs to the field of building materials and is suitable for thermal insulation and sound insulation treatment of building floors. [0003] Background technique: [0004] Floor sound insulation is one of the important factors to ensure the sound environment of residential buildings, but it has not been paid enough attention in the past architectural design. With the development of the economy and society, as well as the gradual improvement of government-related living environment laws and regulations, and the continuous improvement of people's requirements for housing quality, residential design has begun to attach great importance to floor sound insulation. The thickness of the residential floor slabs currently under construction in my country is basically 90-120mm thick reinforced concrete slabs, and the floor-weighted standardized impact sound pressure level cannot meet the design requirements of less than 75db. Traditionally...
