Prefabricated sound attenuating wall system

Abstract

A partially prefabricated sound attenuating partition construction, for the construction of partitions in buildings, and other sound attenuating structures. The partition has two panel assemblies of vertical members defining opposite sides thereof, with a hollow interior. The panels are received in upper and lower generally L-shaped receivers mounted to receive the panel assemblies. A sound attenuating curtain of flexible material is supported from one of the panel assemblies. The sound attenuating curtain is spaced from the second of the panel assemblies by a predetermined air space. A sound attenuation acoustical batting insulation mounted on the other panel assembly within the hollow interior, and, a predetermined airspace between the acoustical batting insulation and the sound attenuating curtain.

1 . a prefabricated sound attenuating partition construction, for the construction of partitions, and the like, such as interior partitions in buildings, and other sound attenuating structures and comprising; 
 first and second panel assemblies for defining opposite sides of said partition construction, and defining a hollow interior between said first and second panel assemblies; and    a sound attenuating curtain loosely secured to one of said first and second panel assemblies and facing into said hollow interior, said sound attenuating curtain being spaced from the other of said first and second panel structures by a predetermined air space.    
     
     
         2 . A prefabricated sound attenuating partition construction as claimed in  claim 1 , wherein said first and second panel assemblies define uooer and lower edges and parallel side edges and including edge channels along opposite side edges of each of said first and second panel assemblies.  
     
     
         3 . A prefabricated sound attenuating partition construction as claimed in  claim 2 , wherein each said first and second panel assemblies comprises two sheets of dry wall material sandwiched together, and with their side edges offset, and wherein said channel defines side walls and a generally zig-zag intermediate wall, encysting said offset edges of said dray wall sheets.  
     
     
         4 . A prefabricated sound attenuating partition construction as claimed in  claim 3 , wherein said channels receive edges of said curtain therein, on said one of said first and second panel assemblies.  
     
     
         5 . A prefabricated sound attenuating partition construction as claimed in  claim 1 , wherein said sound attenuating curtain is a flexible material.  
     
     
         6 . A prefabricated sound attenuating partition construction as claimed in  claim 1  and  5 , including a sound attenuation acoustical batting insulation mounted on the other of said first and second panel assemblies and, 
 a predetermined airspace between said acoustical batting insulation and said sound attenuating curtain.    
     
     
         7 . A prefabricated sound attenuating partition construction as claimed in  claim 6 , wherein said acoustical batting insulation is mounted on the other of said first and second panel assemblies using an adhesive material.  
     
     
         8 . A prefabricated sound attenuating partition construction as claimed in  claim 1  and  7 , wherein said first and second panel assemblies each comprise at least two sheets of building material.  
     
     
         9 . A prefabricated sound attenuating partition construction as claimed in  claim 8 , wherein said at least two sheets of building material is gypsum drywall panelling.  
     
     
         10 . A prefabricated sound attenuating partition construction as claimed in  claim 1  and  10  and including upper and lower generally L-shaped receivers mounted to a ceiling and a floor of the building respectively, to receive at least one said panel assemblies therein.  
     
     
         11 . A prefabricated sound attenuating partition construction as claimed in  claim 11  and including sound attenuating strips extending between said upper L-shaped receiver and said lower L shaped receiver, and overlap adjacent said channels.  
     
     
         12 . A method of erecting prefabricating sound attenuation partitions, said method including the steps of; 
 securing two sheets of building material together, to make a first panel assembly;    installing a series of first panel assemblies having sound attenuating sheet curtain material thereon to the ceiling and floor of a building site, in side edge to side edge abutting relation;    attaching a sound attenuating strip along abutting edges of adjacent said first panel assemblies such that the sound attenuating strip is secured to said sound attenuating curtains on said first panel assemblies, and, installing a series of second panel assemblies to the ceiling and floor of a building site    
     
     
         17 . A method of erecting prefabricating sound attenuation partitions as claimed in claim  16 , and further including the step of installing said second panel assemblies in predetermined spaced relation from said first panel assemblies, thereby defining a space between said first and second panel assemblies  
     
     
         18 . A method of erecting prefabricating sound attenuation partitions as claimed in claim  16 , and further including the step of installing upper and lower receivers to said the ceiling and floor of the building site, and anchoring said panel assemblies to said upper and lower receivers.  
     
     
         19 . A method of erecting prefabricating sound attenuation partitions as claimed in claim  16 , and further including the step of forming further sound attenuating strips and bonding them over junctions between adjacent said first panel assemblies and partially overlapping said sound attenuating curtain to provide a uniform curtain from floor to ceiling.  
     
     
         20 . A method of erecting prefabricating sound attenuation partitions as claimed in  claim 18 , and further including the step of mounting an acoustical insulation to one side of the other of said first or second panel assemblies such that the acoustical insulation is within the predetermined space, between said first and second panel assemblies.
