Description
Techo térmicamente aislante y acústicamente absorbente.Thermally and acoustically insulated roof absorbent.
La invención se refiere a un dispositivo de cubierta de edificio que comprende un soporte de chapa nervada, un paravapor que comprende una capa impermeable al vapor de agua, un colchón térmicamente aislante y una membrana de estanqueidad, mutuamente superpuestos en este orden, recubriendo la membrana de estanqueidad los extremos superiores de órganos de ensamblaje que atraviesan los otros constituyentes antes citados del dispositivo.The invention relates to a device of building roof comprising a ribbed sheet support, a paravapor comprising a water vapor impermeable layer, a thermally insulating mattress and a sealing membrane, mutually overlapping in this order, covering the membrane of sealing the upper ends of assembly organs that cross the other constituents mentioned above of device.
Tales dispositivos son bien conocidos (véase, por ejemplo, el documento FR 2 635 603 A) y están definidos en la norma francesa NF P 84-206. Se conocen, en particular, dispositivos en los cuales la capa impermeable del paravapor es una hoja delgada de aluminio, que, para asegurar su resistencia mecánica y permitir su manipulación, está pegada a una tela de vidrio de una masa por unidad de superficie de aproximadamente 40 g/m^{2}. El paravapor no confiere al dispositivo ninguna propiedad de absorción acústica. Se conoce, igualmente, un dispositivo en el cual el paravapor comprende una capa porosa gruesa que le confiere propiedades de absorción acústica. Esta capa porosa gruesa tiende a aplastarse cuando una persona pisa sobre el dispositivo, especialmente, durante la colocación de éste, lo que implica el inconveniente que a continuación se indica. Los constituyentes del dispositivo están ensamblados entre sí, generalmente, por medio de tornillos que los atraviesan. Para asegurar la continuidad de la estanqueidad, al menos, una parte del espesor de la membrana recubre la cabeza del tornillo. Si una persona pisa en la proximidad de un tornillo, y la capa porosa del paravapor se aplasta en este lugar, resulta un debilitamiento de las capas subyacentes y el tornillo atraviesa la segunda capa de la membrana de estanqueidad, destruyendo la estanqueidad del tejado.Such devices are well known (see, for example, document FR 2 635 603 A) and are defined in the standard French NF P 84-206. They know, in particular, devices in which the waterproof paravapor layer is a thin aluminum sheet, which, to ensure its mechanical strength and allow its manipulation, it is glued to a glass cloth of a mass per unit area of approximately 40 g / m2. He Paravapor does not give the device any absorption property acoustics. A device is also known in which the Paravapor comprises a thick porous layer that gives it sound absorption properties. This thick porous layer tends to crush when a person steps on the device, especially, during the placement of the latter, which implies the inconvenience indicated below. The constituents of device are assembled together, usually by means of screws that go through them. To ensure the continuity of the at least a part of the thickness of the membrane covers The screw head. If a person steps in the vicinity of a screw, and the porous layer of the paravapor is crushed in this place, a weakening of the underlying layers and the screw results crosses the second layer of the sealing membrane, destroying the tightness of the roof.
Se ha descubierto que era posible eliminar este inconveniente, confiriendo al mismo tiempo al dispositivo de cubierta propiedades de absorción acústica.It has been discovered that it was possible to eliminate this inconvenient, while conferring on the device Sound absorption properties cover.
La invención se refiere, especialmente, a un dispositivo del género definido en la introducción, y prevé que el paravapor comprenda, además, una capa de porosidad abierta con una masa por unidad de superficie de, al menos, 240 g/m^{2}, confiriendo al dispositivo propiedades de absorción acústica y no aplastándose, prácticamente, cuando una persona pisa sobre éste.The invention relates especially to a gender device defined in the introduction, and provides that the Paravapor also includes an open porosity layer with a mass per unit area of at least 240 g / m2, giving the device sound absorption properties and not crushing, practically, when a person steps on it.
