Title
(EN) GLASS PANEL
(FR) PANNEAU DE VERRE
Abstract
(EN)
Glass panel provided with a glass panel body (P1) comprising a pair of sheets of flat glass (1) disposed with a thickness-direction gap between them, a suction port (6) formed in one sheet (1A) of the pair of sheets of flat glass (1) and a clearance (V), between the pair of sheets (1), vacuum-sealed through the suction port (6); the suction port (6) being constituted by providing a through hole (1a) in the one sheet (1A), erecting a suction glass tube (7) on the hole (1a), providing a low-melting-point glass seal (S) covering the base end of the tube (7) and the peripheral edge of the hole (1a) in the one sheet (1A), and providing a closed portion (H) formed by closing the tip end of the tube (7) by heating and melting; wherein low-melting-point glass constituting a first seal (S1), corresponding to the one sheet (1A), of the seal is set smaller in thermal expansion coefficient than one sheet (1A).
(FR)
L'invention concerne un panneau de verre muni d'un corps du panneau (P1) qui comprend deux feuilles de verre plat (1) entre lesquelles est ménagé un espace dans le sens de l'épaisseur, un orifice d'aspiration (6) formé dans l'une des feuilles (1A), et un espace vide (V) fermé sous vide entre les deux feuilles à travers l'orifice d'aspiration (6). La réalisation de l'orifice d'aspiration (6) consiste à pratiquer un trou débouchant (1a) dans ladite feuille (1A), à placer verticalement un tube de verre d'aspiration (7) dans le trou (1a), à couvrir l'extrémité de la base du tube (7) et le bord périphérique du trou (1a) dans ladite feuille (1A) au moyen d'un bouchon de verre (S) à point de fusion bas, et à fermer une partie (H) en obturant par thermofusion la pointe du tube (7). Le verre à point de fusion bas constituant un premier joint (S1) correspondant à ladite feuille (1A) présente un coefficient d'expansion thermique inférieur à celui de la feuille (1A).
