Description

Waterproof damping sound insulation floor

Technical Field

The utility model relates to a waterproof damping sound insulation floor belongs to interior decoration technical field.

Background

Along with the higher requirements of people on the living environment, the sound insulation performance of the building acoustic environment and the enclosure structure is more and more emphasized by people. The ' civil building sound insulation design specification ' requires that the sum of weighted sound insulation quantity of household floors and spectral correction quantity of reddish noise is more than 45dB, and the ' impact sound insulation performance of household floors of bedrooms and living rooms ' is that weighted normalized impact sound pressure level is less than 75dB '. Generally, in order to satisfy the above-mentioned sound insulation requirements, the floor structure needs to be subjected to sound insulation treatment. Particularly, in high-demand houses, the sound insulation quantity of the household floor slab is required to be less than 65dB, and if sound insulation design treatment is not carried out, the acoustic performance index can not reach the standard generally. For the floor under the water environment condition, the waterproof problem also needs to be considered, how to solve the sound insulation problem and the waterproof problem simultaneously is the technical problem which needs to be solved by the waterproof sound insulation floor.
