Abstract:
A device which can be fixed to the edge of a panel, for example a sound-absorbing panel formed by heat-bonded synthetic fibres, is described. The device comprises a body with a longitudinal through- hole and two walls which define a cavity for enclosing the edge of the panel. The through-hole communicates with the cavity. The through- hole is configured to guide a threaded element (screw or the like) towards said cavity so that said threaded element engages at least with said edge of the panel so that it expands towards the walls of the cavity and is firmly retained by them.
Abstract:
Disclosed is a building board construction that provides enhanced acoustical properties. In one possible embodiment, the board is a gypsum board with opposing facing sheets and an intermediate set gypsum core. An opened celled polymeric sheet is formed within the gypsum core and gives the resulting board enhanced sound absorption. In an alternative embodiment, individual pieces of polymeric foam are used in stead of the polymeric sheet. Also disclosed are various manufacturing methods whereby boards with enhanced acoustical properties can be formed in an continuous process. The various components of the present disclosure, and the manner in which they interrelate, are described in greater detail hereinafter.
Abstract:
Cerramiento para la construcción, con propiedades de aislamiento acústico, destinado a conformar, o formar parte de, un techo o de una pared, y que comprende una cara exterior conformada en una chapa grecada (1) de acero o aluminio destinada a proporcionar rigidez a la cubierta en cuestión y al menos una capa de lana mineral (3), como aislamiento acústico. Dicho cerramiento comprende al menos una bandeja lisa (2) de acero, dispuesta en un plano paralelo a la chapa grecada (1) y que conforma la cara interior de la cubierta, encontrándose dispuestas entre la placa grecada (1) y la bandeja lisa (2), al menos una primera capa y una segunda capa de lana mineral (4), entre las que se encuentra dispuesta una primera lámina sintética (5) de alta densidad.
Abstract:
A sound absorbing board (1) that is a sound absorbing board where a decorative layer (2) and a rigid substrate material (3) are laminated, and where the substrate material contains parallel grooves (4) spaced at a pre-determined distance, and also, where the cross sectional surface of the grooves in a direction perpendicular to the longitudinal direction of the substrate has a shape that contains mutually adjacent neck parts (4a) and trunk parts (4b) is described. The sound absorbing board has decorative properties and at the same time has sound absorbing, sound isolation properties, and can be easily processed.
Abstract:
A composite panel structure adapted to be supported relative to a mounting surface includes a panel having a first surface and a second surface defining therebetween a thickness of the panel. The panel also has a plurality of perforations arranged in a hexagonal pattern and spanning the thickness of the panel. The perforations provide acoustic transparency to the panel. The composite panel structure further includes a film positioned adjacent the first surface of the panel to attenuate sound waves reflected from the panel.
Abstract:
A sound absorbent barrier (10) has a sound absorbent layer (40) disposed between a porous first cover (50) and a second cover (60). The barrier (10) also has a waterproof sound-permeable membrane (70) between the first cover (50) and the sound absorbent layer (40). The sound absorbent layer (40) is thus protected from damage by the first and second covers (50, 60) and water ingress is prevented by the sound-permeable membrane (70). The second cover (70) may be non-porous to reflect sound waves which have passed through the sound absorbent layer (40) back through the sound absorbent (layer 40). Alternatively, the second cover may be porous to enable absorption of sound from two directions.
Abstract:
A sound absorbing system 10 includes a breathable surface layer 12; a first backing airspace 14 adjacent to the surface layer 12; a perforated substrate 16 adjacent to the first backing airspace 14; a second backing airspace 18 communicated with the first backing airspace 14 through the perforated substrate 16, and a reflecting layer 26 adjacent to the second backing airspace 18. Even when the first backing airspace 14 does not have a dimension necessary to achieve intended sound-absorbing properties, since the first backing airspace 14 is communicated with the second backing airspace 18 through a through hole 20 of the perforated substrate 16, it is possible to achieve intended sound-absorbing properties by the presence of the second backing airspace 18, without increasing the dimension of the first backing airspace 14.
Abstract:
A laminated panel is provided including a first layer of material having external and internal surfaces; a second layer of material having external and internal surfaces; a layer of viscoelastic glue in contact with the internal surface of said first layer of material and with the internal surface of said second layer of material; said glue including an acrylic polymer in a concentration between 10% and 60% by weight, or a tackifier in a concentration between 1% and 70%; or a plasticizing compound in a concentration between 0% and 15%; or a material with Tg greater than 0 °C in a concentration between 0% and 30%. A soundproof assembly is also provided including a first and second panel; at least one spacer between the panels, and a gap between the panels, wherein at least one of the panels comprises a laminated panel as provided above.
Abstract:
La presente invención describe un módulo conductor térmico anti-acústico que se constituye de : por lo menos dos paneles A y B, que pueden ser fabricados en cualquier material, en tamaños y dimensiones diferentes. Los paneles A y B al ser acoplados forman un módulo el cual al estar sus dos caras (2,10) unidas, los canales (3,11) de ambas caras (2,10) forman un conducto pasado (14) en el cual se puede introducir cualquier tipo de material o de servicios como puede ser tuberías para agua o gas (15), cableado para telecomunicaciones (16) como tv, cableado de computadora, teléfono, calefacción o aire acondicionado (18). El panel A cuenta con cámaras termo-acústicas (8) que pueden ser rellenadas de cualquier materia térmica anti-sonora o se pueden quedar sin rellenar. El panel B en su cara frontal (13) puede tener acabados industriales (25) o una malla a la cual se le puede adherir cualquier material como yeso o cemento dependiendo del acabado que desee el usuario.
