Title
(DE) GLASPLATTENKONSTRUKT
(EN) GLASS PLATE CONSTRUCT
(FR) CONSTRUCTION DE PLAQUE DE VERRE
Abstract
(EN) A glass plate construct including at least two plates and a liquid layer held between the two plates, at least one of the two plates being a glass plate. The glass plate construct constitutes a step part presenting a stair shape in a cross-sectional view due to the fact that the end faces of each of the two plates are arranged out of alignment, and further includes a sealant provided so as to seal up at least the liquid layer in the step part.
(FR) Une construction de plaque de verre comprend au moins deux plaques et une couche de liquide maintenue entre les deux plaques, au moins l'une des deux plaques étant une plaque de verre. La construction de plaque de verre constitue une partie étagée qui présente une forme d'escalier dans une vue en coupe transversale en raison du fait que les faces d'extrémité de chacune des deux plaques sont agencées de façon non alignée, et comprend en outre un matériau d'étanchéité disposé de façon à sceller de manière étanche au moins la couche de liquide dans la partie étagée.
