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.

Abstract: The invention relates to methods and devices for mounting a floating floor on a beam structure comprising a plurality of parallel beams, the method comprising positioning a plurality of devices placed at a regular distance and fixing said devices to the beams, the devices comprising a horizontally oriented support, and at least one fixing element comprising a vertical part configured to be secured to at least one lateral wall of a beam, the support being connected to the fixing element. The method also comprises mounting joists by inserting elements consisting of an acoustic insulating material on the supports of the devices, each joist being carried by at least two supports, the combined height of the joists and the acoustic elements being such that the upper surface of the joists is located at a greater height than the beams of the beam structure, and mounting the floor on the upper surfaces of the joists.

Abstract: The invention relates to a structure comprising at least four wooden beams attached to one another by means of connection parts, said metal connection parts (1) having flats that are supported on the faces of a longitudinal channel (G1 or G2) of a first I-shaped or U-shaped beam (PU, PI) and at least one flat supported on at least the central web (2) of another beam (P).
