Description
Technical field
The utility model belongs to sound isolation of floor antivibration area, and in particular to a kind of sound isolation of floor vibration-proof structure.
Background technology
Room noise has a significant impact with the health vibrated for building, indoor private and healthy sexual intercourse user
Normal use.《Residential Building Estimate Information technical standard》（GB/T50362-2005）, house combination property reaches 3A levels, floor meter
Acoustic pressure≤65dB, air-borne sound weighted transmission loss >=50dB are hit in power standardization.《Healthy residence construction technique code》
(CECS179)：2005 weighted standardization hits acoustic pressure recommendation for≤65dB (A).Elevator room, equipment room, pump house, refrigeration machine
The fixed equipments such as group, blower fan, generating set are arranged on interior of building, and noise and vibration can be produced in running, and it is discharged
Measure excessive, can have a negative impact to sensitivity building, influence the health of user.
According to investigation, it is all higher than in one layer of premises of pump house upper ground surface, noise emission amount, 31.5~250Hz sound pressure levels
45dB, peak value belong to low and medium frequency noise, based on low frequency in 125Hz.And according to《Elevator surveillance inspection procedure》Regulation：Machine
Room average noise is not more than 80dB（A）；Normal speed is less than 2.5m/s elevator, and maximum noise is not more than 55dB in sedan-chair in operation
（A）；Normal speed is more than 2.5m/s elevator, and maximum noise is not more than 60dB in sedan-chair in operation（A）；During switch gate, most
Big noise is not more than 65dB（A）.And the vibration and noise of elevator in the process of running is surveyed, if in terms of being not added with vibration damping sound insulation
Technical finesse, it discharges the emission limit requirement for being above healthy residential architecture or ecotecture mostly.
For sensitivity building, fixed equipment room noise emission limit, for I class environment, A classes room emission limit daytime
Between be not more than 40dB, night is not more than 30dB, and 45dB is not more than between B classes room emission limit daytime, and night is not more than 35dB.Equally
Be directed to times the sound pressure level（31.5Hz-500Hz）, it is not more than 76dB~34dB between A classes room emission limit daytime, night is little
In 69dB~24dB.Ecodistrict acoustic environment should meet following standard：Daytime≤45dB；Night≤40dB.
It is seen that, if without special sound insulation and Vibration Absorption Designing and handled, made an uproar after contrast caused by fixed equipment
Exceeded phenomenon be present in sound limit value, and in design and construction, at the vibration and acoustics of fixed equipment noise source
Reason, all difficulty are effective with rational technical measures.The pollution of noise and vibration be present, but be difficult to the crux administered, have a strong impact on
Close on the use of building.For the construct noise propagating characteristic of middle low frequency, analysis spectrum and peak value, take and insulate against sound accordingly with subtracting
Vibration means, the floor vibration isolation way for proposing to be applied to have vibration transaudient are just particularly important.
