Description
:-`` 2~26611 The present invention relates to a material for sound-proofin~ a floor and to floors incorporating same.
The domain of the invention is that of the sound-proofing of buildings, more particularly the sound-proofing of floors, especially from structure-borne noise, or impact sound.
]0 Multi-layer materials have already been proposed for effecting this type of sound-proofing, but they are most often inefficient. It should, moreover, be noted that t~he solution is far from being evident, as the total thickness available to the man skilled 15 in the art for making a floor is limited, and that available for the positioning of sound-proofing mate-rials is even less.
Certain two-layer composite materials have a lower layer constituted by an elastic foam and a 20 bituminous upper layer. Experience has shown the lack of efficiency of these materials, at least when used with thicknesses compatible with the space avai-lable. It may be thought that the heavy upper layer completely crushes the lower layer which no longer 25 performs any insulating role.
$he invention proposes a novel type of material, and a mode of applying this novel material, which make it possible to obtain results which are conside-rably better than all the prior art known up to the ~-~ 30 present time, respecting, of course, the general specifications of construction of buildings, particular-ly concerning the thicknesses allowed.
The invention therefore has for its first object a novel material for sound-proofing a floor, constitu-ted by the assembly of a first, lower, layer of a ' . . i . ~ ~

Experience has shown that the choice of the various constituents in the ranges of values indicated, and particularly the choice thereof at the preferred - 2026~11 values, ensures a noteworthy efficiency in the domain of sound-insulation, particularly from impact sounds.
The overall efficiency observed may be explained by the following indications:
- the first layer (3; 13) of the material (2;
22) compensates any roughness of the surface of the support 1 and thus protects the foam of the second layer (4; 14); in addition, it attenuates the sounds by stopping a considerable part of the sounds of high frequencies;
- the second layer (4; 14) completes sound insula-tion, particularly concerning the impact sounds, and also provides heat insulation, the principal function of the assembly of the material (2; 22) being sound-proofing;
- the latticework (5; 15) ensures a uniform distribution of the filler and thus provides a good, regular foundation for laying tiles 7 or the fibered wear-resisting layer 12 constituting the fifth layer;
:: 20 - the first function of the cement of the third ~:~ (6; 16) and fourth (9; 19) layers is to provide a : good bond between the various elements, without vibra-tory beats, and consequently to obtain a good employ-ment of the material 2; 22. This cement has another : :25 function, that of reinforcing the structures with : which it is in contact. Finally, it has a third func-~ tion, in connection with its noteworthy suppleness: -;~ it remains permanently applied on the surfaces with which it is in contact and provides perfect water-proofing of the floor;
- finally, when it is provided, the panel 10 :~ ~ of extruded polystyrene ensures heat insulation of the floor, whilst completing its sound insulation.
It should furthermore be noted, on the one hand, that the eff~ciency obtained results from the reinforce-ment of the properties of the various constituents, .
2~26611 \
which, separately, would not make it possible to obtain the overall result observedi on the other hand, that the propagation of the vibratory and acous-tic waves is considerably hindered, and the sound insulation obtained, noteworthy, due to the various ruptures in transmission and the various changes of phases which are produced upon passage from one constituent to the other.
The invention is not limited to the embodiments described, but covers, on the contrary, all the va-riants which may be made thereto without departing from the scope nor spirit thereof.

Experience has shown that the choice of the various constituents in the ranges of values indicated, and particularly the choice thereof at the preferred - 2026~11 values, ensures a noteworthy efficiency in the domain of sound-insulation, particularly from impact sounds.
The overall efficiency observed may be explained by the following indications:
- the first layer (3; 13) of the material (2;
22) compensates any roughness of the surface of the support 1 and thus protects the foam of the second layer (4; 14); in addition, it attenuates the sounds by stopping a considerable part of the sounds of high frequencies;
- the second layer (4; 14) completes sound insula-tion, particularly concerning the impact sounds, and also provides heat insulation, the principal function of the assembly of the material (2; 22) being sound-proofing;
- the latticework (5; 15) ensures a uniform distribution of the filler and thus provides a good, regular foundation for laying tiles 7 or the fibered wear-resisting layer 12 constituting the fifth layer;
:: 20 - the first function of the cement of the third ~:~ (6; 16) and fourth (9; 19) layers is to provide a : good bond between the various elements, without vibra-tory beats, and consequently to obtain a good employ-ment of the material 2; 22. This cement has another : :25 function, that of reinforcing the structures with : which it is in contact. Finally, it has a third func-~ tion, in connection with its noteworthy suppleness: -;~ it remains permanently applied on the surfaces with which it is in contact and provides perfect water-proofing of the floor;
- finally, when it is provided, the panel 10 :~ ~ of extruded polystyrene ensures heat insulation of the floor, whilst completing its sound insulation.
It should furthermore be noted, on the one hand, that the eff~ciency obtained results from the reinforce-ment of the properties of the various constituents, .
2~26611 \
which, separately, would not make it possible to obtain the overall result observedi on the other hand, that the propagation of the vibratory and acous-tic waves is considerably hindered, and the sound insulation obtained, noteworthy, due to the various ruptures in transmission and the various changes of phases which are produced upon passage from one constituent to the other.
The invention is not limited to the embodiments described, but covers, on the contrary, all the va-riants which may be made thereto without departing from the scope nor spirit thereof.
