The present invention is a direct-point attachment laminate system comprising: (1) a thermoplastic interlayer; (2) at least one sheet of a rigid structural load-bearing layer (structural layer); (3) at least one receptor means; and (4) at least one attachment means, wherein the thermoplastic interlayer is bonded on at least one surface to at least one sheet of the structural layer, and wherein at least one receptor means is also adhesively bonded to the thermoplastic interlayer and thereby adhesively bonded to the structural layer, wherein the receptor means is positioned to mechanically accept the attachment means, with the further proviso that the attachment means and/or the receptor means are made from materials having a coefficient of expansion that is from about 90% to about 110% of the coefficient of expansion of the structural layer.

La présente invention concerne un système feuilleté à fixation ponctuelle directe qui comprend : (1) une couche intercalaire thermoplastique ; (2) au moins une feuille d'une couche porteuse structurelle rigide (couche structurelle) ; (3) au moins un système de moyens de réception ; et (4) au moins un système de moyens de fixation, la couche intercalaire thermoplastique étant liée, sur au moins une surface, à au moins une feuille de la couche structurelle, et au moins un système de moyens de réception étant également lié de manière adhésive à la couche intercalaire thermoplastique et, de ce fait, lié de manière adhésive à la couche structurelle, les moyens de réception étant placés de façon qu'ils acceptent mécaniquement les moyens de fixation, à la condition supplémentaire que les moyens de fixation et/ou les moyens de réception soient réalisés dans des matériaux possédant un coefficient d'expansion compris entre environ 90 % et environ 110 % du coefficient d'expansion de la couche structurelle.
