[Problems to be Solved by the Invention] In recent years, a point support method of a metal system has been used for an outer wall of an atrium from a bonding method of a frameless method, and a mounting bracket has been bonded to a glass plate disclosed in Japanese Utility Model Publication No. 58-31316. However, in the case of a large plate, there is a disadvantage that the number of mounting brackets becomes extremely large. In addition, there is a problem that it is difficult to drill high-strength holes due to an increase in the number of steps for dishing, and a drop in strength due to the sharp edges from the peripheral edge shape of the holes. To prevent this, a scattering-preventive resin film is stuck, but simply screwing the film and tempered glass together with a metal fitting attaches the spontaneous explosion glass to the bendable shatterproof film and the granulated glass. And, there is a risk of falling by scattering prevention film can not withstand the weight of the glass, Japanese Utility Model 63
Japanese Unexamined Patent Publication (Kokai) No. -37787 requires the use of such a metal fitting for a normal glass plate or the like having a low allowable stress value.
However , it has a drawback that it requires a work of filling a filler in addition to a complicated structure, and the laminated glass disclosed in Japanese Utility Model Laid-Open No. 2-144988 is based on the premise that a normal glass plate is used. The engaging part of the sash frame is engaged with and supported by the step part of the sash frame, and it is leveled to eliminate the step and improve the aesthetic appearance, prevent dust and dirt from collecting on the step, and peel off the adhesive Although it is said that the holding force is prevented from lowering, there is a problem that the line supporting method of the locking portion requires an adhesive filling work and a further curing time as compared with the target point supporting method. .
