Patent ID: 8596003

Claim:
An acoustic complex ( 1 ) for making a floating floor with improved acoustic insulation performance, the acoustic complex comprising: a floor covering ( 5 ) fastened to a floating floor resting on a support ( 3 ) ( 10 ), said floating floor comprising a modular set of rigid prefabricated panels ( 2 ), elastic pads ( 4 ) and wood shims, the elastic pads and wood shims being arranged on a lower face of the panels, between the panels and the support, wherein the floating floor is formed of the modular set of rigid prefabricated panels ( 2 ) having a density between 0.5 and 6 g/cm 3 , limits included, the panels comprising peripheral edges configured for positioning the panels edge-to-edge in order to form a continuous upper surface, at least one of said peripheral edges of each panel comprising a means for adjusting an edge-to-edge positioning of the panels, the means for adjusting comprising complementary male and female structures configured to come into mutual engagement, wherein the elastic pads are homogenous single-piece elements fastened indirectly by the wood shims to the lower face of the panel, each of said elastic pads being substantially of parallelepiped shape, the ratio (Sta/Stp) of the total seating surface area (Sta) of the elastic pads on the support to the total surface area of the panel (Stp), being between 0.03 and 0.08, wherein the wood shims have a thickness between 19 and 25 mm, and wherein the elastic pads are fastened to the wood shims such that the wood shims have slightly longer length than that of corresponding elastic pads fastened thereto, the wood shims being fastened under the panel, and the elastic pads and the wood shims forming parallel discontinuous lines.
