JPH10299351A - Glazing channel for double glazing and fitting structure thereof - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a glazing channel for double glazing and its fitting structure obtaining excellent adhesion between the glazing channel and the peripheral edge part of the double glazing and prevent separating deformation of the fitted glazing channel. SOLUTION: This glazing channel 1 is fitted in the state of surrounding the outer peripheral side of a spacer disposed between two opposed glass panes 23 and the outer peripheral part of double glazing 28 with a sealant filled between the glass panes 23. In this case one or more angular or cylindrical protruding parts 12 are provided at the inner bottom face of the glazing channel 1 of approximately U-shape cross section. The outer peripheral part of the double glazing 28 is surrounded by the glazing channel 1 before the sealant filled around the outer periphery of the double glazing 28 is solidified, and the sealant is solidified after embedding the protruding parts 12 of the glazing channel 1 in the sealant.

題があった。In any of the above, after the Grechan was attached to the peripheral edge of the double-glazed glass sheet, there was a risk of deformation such as lifting near the center of the linear portion. Further, for example, in the bead material in the double-layer glass structure described in Japanese Utility Model Application Laid-Open No. 7-15989, a bead material is fixed and arranged in advance on the exposed peripheral edge of the glass plate. A hard bead portion provided with a fitting protrusion to be fitted and covered on the peripheral surface of the double-glazed glass, and a portion of the hard bead portion which covers the exposed peripheral portion of each glass plate. It is formed with a soft bead part to be provided, and a hard bead part is fitted or only a soft bead part with a hollow part on the-side is not necessarily sufficiently simplified. It is hard to say that the Grechan structure. Further, when trying to press-fit the fitting protrusion of the bead material into the fitting groove provided in the spacer described in this publication, the adhesive between the peripheral portion of the glass plate and the side of the spacer is not completely solidified. If the bead material is to be mounted at this stage, the position of the spacer is shifted from a predetermined position, so that there is a problem that the bead material cannot be mounted until the adhesive is solidified.
