DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double glazing to which a point support method is applied in forming a glass screen with a double glazing and a supporting structure thereof.

[0002]

2. Description of the Related Art As a typical method of mounting a double-glazed glass, 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. SSG construction method (St
ructural Sealant Glazing System). For example, in the text of Japanese Utility Model Publication No. Hei 7-12621, there is disclosed a laminated glass in which the inner periphery of a double-sided glass is bonded to a structure seal portion of a sash frame, or a large-sized gasket is used to form the double-glazed glass into a sash frame. And Japanese Patent Application Laid-Open 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 of the periphery of the double-layer glass, has a multilayer structure. A structure having a structure in which a sash with a leg is engaged with a mounting groove provided on a non-insertion surface of a molded member by being inserted and adhered to a hollow portion of glass has been disclosed.

Another method of forming a glass screen is a point support method using metal fittings. In this point support method, an attachment portion is fixed to a frame, a support member having an X-shape or an H-shape is provided from the attachment portion, and a mounting member is provided at the tip of the arm of the support member at four corners of a double-layer glass. There is known a four-point support structure for supporting a glass plate through a hole.

For example, Japanese Patent Publication No. 7-18200 discloses a sealed double-glazed unit in which an outer glass plate and an inner glass plate are separated from each other by a peripheral seal and bonded to each other, and the unit is mounted on a wall of a building. 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.

Further, in the device disclosed in Japanese Patent Publication No. 4-29824, corners of the inner glass plate of two opposing glass plates are cut off, and the outer glass is cut along the contour of the inner glass. There is disclosed an apparatus which is sealed via a spacer, provided with a bolt through hole in a flange region formed at a corner of the outer glass, and supports the double-glazed glass with a bolt inserted through the through hole.

[0006]

Problems to be Solved by the Invention
Japanese Patent Application Laid-Open No. 4-119590 and Japanese Unexamined Utility Model Publication 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 double-layer glass and the inner glass is attached to the sash frame. Or by bonding a gasket to the recess between the edges of the two glass plates, and fixing the double-glazed glass by fixing the gasket to the sash frame, The provided sash frame is indispensable and effective for supporting double-glazed glass,
There was a problem that visibility was lacking.

[0007] 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 unsupported side 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 multi-layer glass 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 double-glazed glass, the perforated portion may be overloaded, and the perforated portion of the glass plate is countersunk. Also, the head portion is tapered, the structure is complicated, processing takes time, and the manufacturing cost is high.

[0008] Further, with respect to the structure disclosed in Japanese Patent Publication No. 4-29824, the double-layer glass is supported only by the through-holes provided at the corners of the outer glass plate, so that the load on the through-holes is large. Since a tapered countersunk hole is further formed in the through hole, the processing requires time and the manufacturing cost is high.

[0009]

[0037]

According to the present invention, since the double-glazed glass having a high heat-insulating effect is supported by the point support bracket, a glass screen made of the double-glazed glass can be formed without a sash and the visibility is improved.
Since the perforated portion of the glass plate is provided on the outer peripheral side of the spacer frame material, there is no danger of intrusion of moist air from the perforated portion.
The air layer between the two glass plates is kept airtight, the desiccant contained in the spacer frame works effectively, the air layer can be kept dry for a long time, and the seal around the perforated area The structure can be simplified and the structure can be simplified, so that costs can be reduced,
The yield is also greatly improved.

Further, an annular spacer having the same thickness as that of the air layer is provided around the perforated portion of the two glass plates made of double-glazed glass, and the perforated portion is further provided with the shaft portion of the fastening plate, the cylindrical collar, and the cylindrical shape. Because the tightening strength is regulated by the members etc., even if the double glazing is screwed tightly with the bolts and nuts of the tightening plate, excessive force is applied to the perforated part of each glass plate due to overtightening. None, and furthermore, it is tightened and supported on both sides of the perforated part of the multi-layer glass and on the inside of the perforated part via rubber or other elastic cushioning material. However, the effect is remarkable, for example, it can be absorbed by compressive deformation of the elastic material such as the cushioning material or rubber.
