Description
Technical field
The utility model relates to the dual sound-proof wall structure of a kind of building, belongs to civil construction body of wall technical field.Be specially adapted to architecture indoor the sound insulation of wall in noise source room is arranged.
Background technology
Healthy residence, ecological residence etc. from the acoustic environment angle, propose concrete requirement to room noise discharging, room noise, sound insulation of wall etc.The sound insulation factor of body of wall is to estimate the index of body of wall noise insulation ability, and this value is bigger, explains that defening effect is good more.Studying data at home and abroad shows, the building partition sound insulation factor is during greater than 50dB, and the general noise in next door can't hear, and can satisfy the desirable requirement that does not receive next door noise and indoor talk " privacy "; When sound insulation factor was low to moderate 40dB, environment quietly under the situation around then maybe " walls have ears ", even the common voice in next door can both " several pleasant ".The national subordinate's of academic board of Canada building science academy suggestion: the reasonable target of sound insulation of wall value is 55dB.Eliminate noise if desired for a full due from the neighbour's, the desirable sound-insulation value of body of wall should be 60dB or more than.Investigation result shows: STC ≧ 55 dB are real-world objects of the sound-insulation value of party wall; STC ≧ 60 dB belong to better target, block the noise from adjacent room effectively; STC ≧ 65dB, professional recording room, luxurious hotel and high-end villa etc.
The body of wall that adopts in the building at present comprises concrete wall, blockwork, lightweight wall, sheet material body of wall etc., handles and quality control on construction if say nothing to learn, and general body of wall all is difficult to reach 50dB sound insulation needs, brings the noise puzzlement for user or user.And the equipment room that noise source is arranged that is provided with in the building, like generator room, air conditioning room, pump house etc., the responsive construction area around the vibration of its generation and noise are directly delivered to space enclosing structure, comprises that the body of wall processing of insulating against sound then seems particularly important.
Summary of the invention
The utility model provides a kind of building dual sound-proof wall structure, is used to solve the sound insulation of wall problem that equipment room, pump house etc. have the noise source room.
The utility model is realized with following technical scheme: the dual sound-proof wall structure of a kind of building; This dual sound-proof wall is a compound wall, comprise the heavy body of wall that is positioned at noise-sensitive construction area one side, be positioned at the lightgage steel joist wallboard of noise source zone one side and be clipped in the heavy body of wall and the lightgage steel joist wallboard between air layer;
Described heavy body of wall comprises that surface density is not less than 360kg/m
2, blockwork or body of wall surface density that individual layer body of wall air weighted transmission loss is not less than 45dB are not less than 360 kg/m
2, thickness is not less than the reinforced concrete wall of 150mm;
Described lightgage steel joist wallboard is made up of the outermost double-deck sound insulating panel sound insulation sound-absorbing material layer inboard with being fitted in double-deck sound insulating panel; Between lightgage steel joist wallboard and heavy body of wall, a plurality of cushion blockings and lightgage steel joist are installed, the lightgage steel joist wallboard is fixed together through lightgage steel joist and cushion blocking and heavy body of wall.
Described air layer thickness is not less than 20mm.
The beneficial effect of the utility model is: the dual sound-proof wall of the utility model, air sound insulation factor can reach more than the 55dB, can build good indoor acoustic environment, improve the sound insulation of wall effect; And easy construction.
