Description of the Related Art As a typical method of mounting a double-glazed glass sheet, a structural sealant such as silicon is filled between a structural frame such as a sash frame and two or four sides around the indoor side of the double-glazed glass. There is an SSG construction method (Structural Sealant Glazing System) that firmly supports the adhesive. For example, in the text of Japanese Utility Model Publication No. Hei 7-12621, the multilayer glass sheet is formed by bonding the peripheral portion of the indoor glass to the structure seal portion of the sash frame, or using a large gasket to form the multilayer glass sheet. There is a description of a structure to be attached to a frame, and Japanese Unexamined Utility Model Publication No. 4-119590 filed by the present applicant discloses that a concave molded member housed on the inner surface of the edge of the glass plate which is the outer surface side at the periphery of the multilayer glass is a multi-layer glass. A structure having a structure in which a sash with legs is engaged with a mounting groove provided on a non-insertion surface of a molded member by inserting and bonding the cavity into a hollow portion of a laminated glass is disclosed.

In this point support method, an attachment portion is fixed to a body, an X-shaped or H-shaped support member having an arm shape is provided from the attachment portion, and holes are drilled at the four ends of a multilayer glass plate at the tip of the arm of the support member. There is known a four-point support method for supporting a glass plate through a mounting hole.

At least one mechanical mounting structure for mounting to a support structure is provided, and the mechanical mounting structure is attached to one of the glass sheets, and the other is attached to the other glass sheet with a gap left. There is disclosed a mechanical mounting structure in which a boss is interposed in a hole between both glass plates and the boss is sealed to both glass plates.

Japanese Patent Application Laid-Open No. 4-119590 and Japanese Utility Model Application Laid-Open No. 4-119590 are frameless because the sash frame is not exposed to the front surface of the outer wall, but the sash frame is provided on the indoor side of the multilayer glass plate, and the sash frame is provided inside the sash frame. Since a glass plate is bonded or a gasket is fitted into a concave portion between two glass plate edges, and the gasket is attached and fixed to the sash frame, the double glazing is fixed. The sash frame provided inside is indispensable and effective for supporting double-glazed glass, but there is a problem that visibility is lacking.

し、製作コストも高いものとなっている。[0006] Japanese Patent Publication No. 7-18200 discloses that a perforated portion of one glass plate of a double glazing is sandwiched between a boss and a bush made of nylon, and the other glass plate is formed of a double glazing. If the glass plate deforms due to wind pressure or the like, it is merely a seal ring and the sealing material seals the gap between the boss, and the support metal becomes support of only one glass plate, Since the sealing ring and the sealing material of the perforated portion of the glass plate on the side that is not supported are repeatedly deformed, the sealing ring and the sealing material are deteriorated by use over time, and even in a slight crack, the sealing property in the multilayer glass plate is reduced. There is a great risk of being damaged. In addition, since the wind pressure load and the weight of the glass plate are supported by sandwiching only one side of the multi-layer glass plate, the perforated portion may be overloaded, and the perforated portion of the glass plate is countersunk. The bush also has a tapered head, has a complicated structure, requires time for processing, and has a high manufacturing cost.
