Floating floor structure for sound insulation and vibration reduction of buildings

Abstract

The invention discloses a floating floor structure for sound insulation and vibration reduction of buildings, and is suitable for design and construction of the sound insulation and vibration reduction of cast-in-place floors of housings, hotels, guest houses and the like with high requirements. The floating floor structure comprises a structural wall body and a floor, wherein flexible vibration reduction units are arranged at equal intervals on the upper surface of the floor, and flexible backing boards which are tightly close to the structural wall body are arranged at the periphery of the floor; a supporting layer is arranged on the flexible vibration reduction units; stuffing units are arranged in the space between the supporting layer and the floor; a floating unit layer is paved on the supporting layer; the flexible backing boards are higher than the floating unit layer, and skirting boards which are tightly close to the flexible backing boards are arranged at the periphery of the floating unit layer; sealant is stuffed to the upper ends of the flexible backing boards. According to the floating floor structure disclosed by the invention, high-quality requirements for sound environment of the sound insulation and the vibration reduction of building floors are met, noise caused by indoor activities is separated through the floors, the trouble of structural sound transmission is avoided, and the floating floor structure meets the comprehensive function requirements for sound insulation, vibration reduction, heat preservation and energy conservation.

Description

technical field [0001] The invention relates to the construction technology category of sound insulation and vibration reduction of building floor slab structures, in particular to a building sound insulation and vibration reduction floating floor structure, which is suitable for the design and construction of sound insulation and vibration reduction of cast-in-place floors for high-demand residences, hotels, and guesthouses. Background technique [0002] How to reduce the impact of noise and vibration from upstairs and downstairs, indoor and outdoor activities between neighbors, improve the quality of the acoustic environment of the house, and involve the sound insulation and reduction of building floors vibration problem. In the "Technical Standards for Residential Performance Evaluation" (GB / T50362-2005), the comprehensive performance of residential buildings reaches the "3A" level, and the sound insulation performance of floors and walls must meet the requirements. It i...

AI Technical Summary

Problems solved by technology

According to data statistics and on-site acoustic sampling tests, if the floor is not treated, most of the impact sound of the floor will not meet the sound insulation requirements of the 3A level of residential comprehensive performance

[0003] The existing floor sound insulation and vibration reduction treatment can not solve the crux of the problem of air sound transmission and structural sound transmission, especially it is difficult to achieve air sound insulation of more than 65dB, and floor impact sound pressure does not exceed 60dB.
