CA 2473174

A floor laying material whose sound absorbing property and sound insulating property are optimized; a piece mat; and an arranging structure thereof. A floor laying material (10) comprises a carpet layer (11) having joining strips (11a) of thermoplastic resin discontinuously arranged on the back surface thereof, and a cushion material layer (12) laminated to the back surface of the carpet layer (11) through the joining strips (11a). The carpet layer (11) has its front-to-back flow resistance value adjusted to be between 100 Nsm-3 and 1000 Nsm-3. Further, the cushion material layer (12) is made of a raw material having an air wrapping property and has its front-to-back flow resistance value adjusted to be between 40 Nsm-3 and 800 Nsm-3.

L'invention concerne un matériel de revêtement de sol, dont les propriétés absorbante et d'isolation phonique sont optimisées. Elle concerne également une moquette en coupon, et une structure d'installation du matériel. Un matériel de revêtement de sol (10) comprend une couche de moquette (11) présentant des bandes d'assemblage (11a) en résine thermoplastique disposées de façon discontinue sur l'envers de la couche; et une couche d'un matériau en mousse (12) contrecollée à l'envers de la couche de moquette par les bandes d'assemblage (11a). La valeur de résistance directe et inverse de la couche de moquette (11) est ajustée entre 100 et 1000 Nsm?-3¿. De plus, la couche de matériau en mousse (12) est faite d'un matériau brut présentant des propriétés d'enroulement de l'air, et dont la valeur de résistance directe et inverse est ajustée entre 40 et 800 Nsm?-3¿.
