Point family floor air-borne sound sound insulation property Rw+C >=45dB in living room, separates point family floor air-borne sound of house and non-domestic use
Sound insulation property Rw+C >=51dB.And in Residential Building Estimate Information, the identification to " 3A " high request Residential Property then requires Separate Home
The air-borne sound and shock acoustic pressure of floor are satisfied by requiring.
How house solves the outdoor noise of house, neighbourhood's activity and makes an uproar as the residential architecture of more sensitivity affected by noise
The negative effect to occupant's life rest such as noise, equipment running noises, traffic noise in sound, stair.Need to be effectively improved
The sound insulation of the building enclosure of residential architecture and vibration ability, and point family floor belongs to the important fender member of building, solves it and makes an uproar
The adverse effect of sound and structure-borne sound transmission, is just particularly important.
Divide the present situation of family floor heat insulating and sound insulating, due to the shadow by factors such as building floor height, structure load-bearing, finishings
Ring, particularly carry out sound insulation processing in inhabitation floor layer, actual beneficiary is user downstairs, should give and examines during floor sound insulation design
Consider and implement in construction.If waiting house to be delivered for use, then floor heat insulating and sound insulating processing is carried out, there is and upstairs handle downstairs
Be benefited, and the situation that the person of exerting oneself can not be benefited.
Although the sound insulation index of point family floor has the regulation of specification, but in design, construction, management link, but lacks technology
Aspect, the technology linking and supporting support of the design and construction that particularly insulates against sound, causes the confusion of following noise, but be difficult to improve excellent
The predicament of change.
The content of the invention
The problem of existing for above-mentioned prior art, the utility model provides a kind of low frequency flexible acoustical insulation floor, to solve
Divide weak point of the family floor in terms of low-frequency noise and vibration.

Further, the concrete layer is in-situ reinforced concrete slab or prefabricated reinforced concrete floor, it is desirable to structure
Floor surface density is not less than 280kg/m2, surfacing, a main load-bearing effect.
Further, flexible isolating layer is laid on concrete layer, for isolating for abatement low-frequency noise and Vibration propagation
Pad, especially to the improvement and effect of optimization of 50Hz-80Hz frequency noises than more significant.
Further, the light-weight aggregate porous concrete layer is that dry density is 850~1000 kg/m3, intensity be 8.0~
10.0MPa lightweight, porous concrete layer, can effectively improve air-borne sound oise insulation factor, and noise transmission decay can be made obvious.
Further, the elastic damping transition zone has larger improved combination soft for that can have frequency to structure floor system
Pad, can effectively reduce the shock acoustic pressure of floor, improve noise situation.
Further, the parquet floor is with CO absorption2Ability and be no less than 40,000,000/cm2Closed airbag
Alveolate texture cork flooring, with environmental protection, noise reduction, anti-skidding function.
It is preferred that, the concrete layer structure plate thickness is 120mm, and strength grade of concrete is C35, structure sheaf mass density
For 300 kg/m2。
It is preferred that, the isolation pad be use polyester felt PF and EPS synthesize and thickness for 30mm isolation pad.
The beneficial effects of the utility model are：By setting flexible isolating layer, installing floor can be effectively reduced with reference to cushion
Acoustic pressure is hit, by setting light-weight aggregate porous concrete layer and cork flooring, air-borne sound oise insulation factor can be effectively improved；The coupling of system
Synergistic effect is closed, the sound insulation damping capacity of point family floor can be effectively improved；Low frequency in the floor of noise-sensitive structure point family is made an uproar
The improvement of sound is particularly evident, is particularly pointed to the improvement of below 63Hz band noises.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1st, concrete layer, 2, flexible isolating layer, 3, light-weight aggregate porous concrete layer, 4, elastic damping transition zone, 5,
Parquet floor.
