Novel partition comprising plasterboards with improved acoustic properties

Abstract

A partition includes a plurality of posts and a plurality of plaster boards on each side. Unitary spaces defined by the posts and the boards are divided into between 3 and 1000 volumes per m 2 and, preferably, at least 6 volumes per m 2 , and a method of producing the inventive partition.

1 - 13 . (canceled)  
   
   
       14 . A partition comprising a plurality of studs and a plurality of boards on each side forming unit spaces between the studs and the plurality of boards, and a grid in which the unit spaces delimited by the studs and the boards are divided into 200 to 1000 volumes per m 2  by the grid which has a thickness less than a distance between the boards.  
   
   
       15 . The partition according to  claim 14 , wherein the unit spaces are divided into 200 to 600 volumes per m 2 .  
   
   
       16 . The partition according to  claim 14 , in which the unit spaces are divided by the grid, this grid being glued at most to the boards on one side of the studs.  
   
   
       17 . The partition according to  claim 16 , in which the grid has a thickness of 70 to 98% of the distance between the boards.  
   
   
       18 . The partition according to  claim 16 , in which the grid is a grid in the form of a honeycomb.  
   
   
       19 . The partition according to  claim 16 , in which the grid is made of cardboard.  
   
   
       20 . The partition according to  claim 14 , in which the unit spaces are divided by a grid, and the grid is not glued to the boards.  
   
   
       21 . The partition according to  claim 14 , in which the boards are plaster boards.  
   
   
       22 . A partition comprising a plurality of studs and a plurality of boards on each side forming unit spaces between the studs and the plurality of boards, and a grid in which the unit spaces delimited by the studs and the boards are divided into 200 to 1000 volumes per m 2  by the grid which has a thickness less than a distance between the boards, the grid not being glued to the boards, said partition further comprising upper and lower rails holding the studs and between which the grid is held.  
   
   
       23 . The partition according to  claim 22 , wherein the unit spaces are divided into 200 to 600 volumes per m 2 .  
   
   
       24 . The partition according to  claim 22 , in which the upper and lower rails have pre-cut tabs which can be folded back inwards and which are inserted into the grid.  
   
   
       25 . The partition according to  claim 22 , in which the grid has a thickness of 70 to 98% of the distance between the boards.  
   
   
       26 . The partition according to  claim 22 , in which the grid is a grid in the form of a honeycomb.  
   
   
       27 . The partition according to  claim 22 , in which the grid is made of cardboard  
   
   
       28 . The partition according to  claim 22 , in which the boards are plaster boards.  
   
   
       29 . A method for the production of a partition according to  claim 14 , the method comprises providing a plurality of studs and a plurality of boards, and dividing unit spaces delimited by the studs and the boards into 200 to 1000 volumes per m 2  by a grid with a thickness less than the thickness of an air space between the boards.  
   
   
       30 . The method of  claim 29 , wherein the unit spaces are divided into 200-600 volumes per m 2 .  
   
   
       31 . The method according to  claim 29 , further comprising attaching the grid to rail at a top of the studs, and extending the grid to another rail, and it is fixed to the latter rail.
