MODULAR ACOUSTIC COMPLEX FOR IMPLEMENTING AN IMPROVED PERFORMANCE FLOOR WITH ACOUSTIC INSULATION AND METHOD OF IMPLEMENTING THE SAME

摘要

The invention relates to an acoustic complex (1) for acoustic insulation, the complex comprising a floor covering (5) fixed on a floating floor with elastic pads (4) resting on a support (3) (10), said floating floor comprising substantially elastic shoes (4). According to the invention, the floating floor consists of a modular assembly of prefabricated rigid panels (2) with a density of between 0.5 and 6, positioned edge-to-edge with male or female positioning adjustment means, the pads being homogeneous monobloc elements fixed on the underside of the panel, the ratio of the total seating surface Sta of the pads on the support on the total surface of the panel Stp, Sta / Stp being between 0.03 and 0.08. In a variant of the shims are interposed between the pads and the panel. In the implementation method, a layer of a fibrous insulation between the support and the floating floor can be interposed.
