Embodiment Construction
[0015] The following is a specific embodiment of the present invention, and the present invention will be further described in conjunction with the accompanying drawings.
[0016] Such as figure 1 As shown, in an intercontinental hotel project, the guest room floor is cast-in-place reinforced concrete floor slab, the thickness is 140mm, and the surface flatness of the structural floor slab is ≤5mm. There are frequent activities on the top of the guest room, and the impact of noise and vibration is relatively large. The floating floor structure is adopted for building sound insulation and vibration reduction to meet the design index requirements of the floor acoustic environment.
[0017] The upper surface of the floor 1 is equidistantly arranged with elastic damping units 3. The elastic damping units are vibration-isolation rubber pads. According to the load statistics on the upper part of the floor, the vibration-isolation rubber pads are selected as independent modules with ...

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...
