Floor cassette for the construction of a floor

Abstract

The invention relates to a floor cassette for the construction of a floating floor, the floor cassette comprising a wooden base panel and a plurality of wooden beams attached to one of the surfaces of the base panel, the beams being essentially parallel to one another, wherein the floor cassette further comprises a plurality of support devices mounted between two adjacent beams, the support devices comprising two ends respectively fixed at least to a lateral wall of the two adjacent beams, and a central part connecting the two ends, the central part being configured to support the floor so that the latter is not directly attached to the beams.

         3 . Floor cassette according to  claim 2 , in which a plurality of acoustic elements respectively attached to the central parts of the support devices form part of the floor cassette. 
     
     
         4 . Floor cassette according to  claim 3 , in which a plurality of said joists attached to the acoustic elements form part of the floor cassette. 
     
     
         5 . Floor cassette according to  claim 4 , in which the floor cassette comprises a part of said floor attached to the joists. 
     
     
         6 . Floor cassette according to  claim 1  in which the floor cassette comprises a thermal insulation material between the base panel and the support devices and/or above the support devices. 
     
     
         7 . Floor cassette according to  claim 1 , in which the base panel has a rectangular shape and in which the length of the base panel exceeds the length of the beams on both sides of said beams. 
     
     
         8 . Floor cassette according to  claim 1 , in which the beams are attached to the surface of the base panel by at least a glue. 
     
     
         9 . Floor cassette according to  claim 8 , in which said glue is a polyurethane-based glue applicable in liquid form and hardening with moisture from the wood and/or from the air. 
     
     
         10 . Floor cassette according to  claim 1 , in which the length of the floor cassette measured in the direction of the beams is between 6 and 12 m and the width of the floor cassette is between 1 and 3 m. 
     
     
         11 . Floor cassette according to  claim 1 , in which the support devices are mounted alternatingly on the channels formed by the beams. 
     
     
         12 . Floor cassette according to  claim 1 , in which at least one end of the support devices is an angle-bracket-shaped element comprising a vertical part and a horizontal part, the horizontal part being fixed to the upper surface of a beam and the vertical part being fixed to a lateral wall of the same beam, the central part being connected to the vertical part. 
     
     
         13 . Floor cassette according to  claim 12  in which the ends comprise a second horizontal part that supports the central part. 
     
     
         14 . Floor cassette according to  claim 1 , in which the ends are angle-bracket-shaped elements comprising a vertical part and a horizontal part, the vertical part being fixed to a lateral wall of a beam, the horizontal part supporting the central part of the support device. 
     
     
         15 . Floor cassette according to  claim 12 , in which the ends are fastened to the central part and oriented at obtuse angles different from 180° defined relative to the central part in a horizontal plane when the floor cassette is installed, said angles being opposite one another. 
     
     
         16 . Floor cassette according to  claim 13 , in which the central part of the support devices is formed by a steel or wooden bar. 
     
     
         17 . Floor cassette according to  claim 12 , in which one or more of the support devices is fabricated from steel plate or formed by the assembly of a plurality of parts of a steel plate. 
     
     
         18 . Floor cassette according to  claim 11 , in which the length of the central part of at least one of the support devices is adjustable when said device is removed from the floor cassette. 
     
     
         19 . Floating floor comprising one or more floor cassettes according to  claim 1 . 
     
     
         20 . Use of one or more floor cassettes according to  claim 11 , for the construction of a floating floor.
