ACOPLAMIENTO MACHIHEMBRADO ENTRE PANELES DE CONDUCTOS DE AIRE ACONDICIONADO AUTOPORTANTES

Acoplamiento machihembrado entre paneles de conductos de aire acondicionado autoportantes, del tipo de los constituidos a partir de un núcleo de material aislante, preferentemente lana mineral, que se complementa con sendas capas externa e interna a base de aluminio u otro revestimiento como pueda ser Kraft-Aluminio, tejido de fibra de vidrio reforzado, velo de vidrio plástico o similares, presentando el canteado o borde de enfrentamiento entre los paneles un corte oblicuo respecto a la horizontalidad o línea longitudinal intermedia en la unión entre ambos paneles, prolongando la capa o revestimiento de aluminio que determina la cara interior del conducto mas allá del borde del panel, fijándose a la superficie oblicua que define el perfil de acoplamiento. The invention relates to a tongue-and-groove coupling between panels of self-supporting air-conditioning ducts and the like, of the type that is provided in order to establish an optimum fit of the canted edge corresponding to the panels that are coupled in a tongue-and-groove manner, and also, to avoid the air coming into contact with the core of the duct therein. To this end, the panels consist of a core of insulating material complemented by an outer layer and inner layer based on aluminum or some other coating, the juxtaposing canted edge or edge between the panels having an oblique cut in relation to the horizontality or longitudinal intermediate line in the joint between the two panels; the aluminum layer or coating, which determines the inner face of the duct, extending beyond the edge of the panel, and being fixed to the oblique surface that defines the coupling profile.
