Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a laminated glass mounting structure.

[0002]

2. Description of the Related Art In recent years, there are many cases in which an outer wall is constructed by supporting a plate glass such as a plate glass on the body side by using an outer wall construction method such as a curtain wall construction method.

In order to maintain the living environment inside a building from the external environment, since the characteristics such as earthquake resistance, wind pressure resistance, and waterproofness are required for the structure by the above-mentioned outer wall construction method, it is necessary to use a plate glass or the like. The plate-shaped member is fixed and supported by a strong support frame member.

Therefore, there is a disadvantage that the continuity of the plate surface formed of plate glass or the like is impaired by the support frame member.

FIG. 9 is a perspective view of a conventional plate glass mounting structure disclosed in Japanese Patent Laid-Open No. 5-179739.
The outer wall can be constructed without impairing the continuity of the plate surface.

Mounting holes 2, 2, 2 and 2 are opened in the plate glasses 1, 1, 1 and 1, respectively, and mounting metal parts 31, 31, 3 are attached.
1, 31 are attached, and these attachment hardware 31 are connected to and supported by a supporting member 32 and a supporting member 33 to a frame (not shown).

FIG. 10 is a perspective view of a laminated glass mounting structure of the first comparative example, and FIG. 11 is a cross-sectional view of a main part of the comparative example of FIG. 10, showing a laminated glass mounting structure to which the above conventional example is applied. As shown, the use of laminated glass has high strength and has an effect of preventing scattering.

As shown in the drawing, a fitting 31 is fitted to the laminated glass 21 via a gasket member 10, and is screwed by a nut member 6 with a washer member 7 interposed.

The laminated glass 21 is an outer plate glass 22 in which an attachment hole 2 having an enlarged diameter slope 3 is formed.
And the inner plate glass 23 in which the hole 25 is opened,
It is made to adhere by the adhesive layer 24.

The socket portion 4 is fitted into the mounting holes 2 and 25 through the gasket member 10. A ball stud 8 pivotally supporting a sphere portion 9 is connected to the socket portion 4 via its receiving portion 5. By supporting the ball stud 8 on the side of the body, a plurality of laminated glass plates 21 are used to move up and down. The same vertical surface in the left-right direction can be continuously formed. Reference numeral 11 is a cushioning material, reference numeral 13 is a sealing material,
Reference numeral 71 is a male screw portion.

As explained above, the mounting hardware 31 is
The whole laminated glass 21 is attached so as to be sandwiched between the expanded diameter socket portion 4 and the nut member 6.

FIG. 12 is a cross-sectional view of an essential part of a laminated glass mounting structure of the second comparative example. As shown in the figure, a mounting metal member 31 is fitted to a laminated glass 21 via a gasket member 10, and a washer is used. It is screwed by a nut material 6 with a material 7 interposed.

The laminated glass 21 is an outer plate glass 22.
And an inner plate glass 23 in which the mounting hole 2 having the enlarged diameter slope portion 3 is formed, are bonded via an adhesive layer 24.

A socket portion 4 is fitted in the mounting hole 2 via a gasket member 10. A ball stud 8 pivotally supporting a ball portion 9 is connected to the socket portion 4 via a receiving portion 5 thereof, and the ball stud 8 is supported on the body side. Reference numeral 11 is a cushioning material, reference numeral 71 is a male screw portion, reference numeral 72 is a countersink portion, and reference numeral 73 is a peripheral wall portion.

The ball portion 9 is adapted to rotate slightly within the receiving portion 5 about the point C, and when the laminated glass 21 is deformed by wind pressure or the like, it is generated in the countersink portion 72. Relieves stress.

Therefore, according to the above-mentioned first and second comparative examples, while the laminated glass is used, the strength of the glass is high and the scattering is prevented, and the continuous glass surface is obtained without using the supporting frame member. It will be possible to secure the sex.

[0017]

However, according to the first comparative example, in order to form the laminated glass 21, the outer plate glass 22 and the inner plate glass 23 are bonded by the adhesive layer 24 such as an elastic resin. In this case, a compressive force is locally applied to a portion of the mounting hardware 31, which is sandwiched between the expanded socket portion 4 and the nut member 6, so that the adhesive layer 24 of the sandwiched portion is crushed, or the plate glass on the outside is crushed. The adhesive layer 24 protrudes outward from the surface sandwiched between the sheet glass 22 and the inner plate glass 23, the laminated glass becomes thin in the thickness direction, the laminated glass 21 is locally deformed, and the sandwiched portion of the sheet glass forming the laminated glass 21. A large bending stress is generated in the plate glass, and these plate glasses, especially the inner plate glass 23, cannot withstand the stress and may be damaged.

Further, as shown in FIG. 9, when supporting the plate glass 22 made of a single plate, the watertightness of the mounting hole 2 is controlled by a rubber ring in the gap between the plate glass 22 and the washer material (not shown). It was secured using (not shown),
When the laminated glass is supported by the conventional supporting method as in the first comparative example shown in FIGS. 10 and 11, the mounting holes 2 and the holes provided in the outer glass 22 and the inner glass 23 constituting the laminated glass. In order to fill the clearance portion of the hole diameter of 25 and secure the watertight performance, it is necessary to use a wet method of using the sealing material 13 or the like, which causes a problem of poor workability.

Further, in the second comparative example, a flat glass surface in which holes are not processed is obtained in the plate glass on the outdoor side, but after the mounting metal member 31 is mounted on the plate glass 23, the laminated glass is processed. Therefore, the workability of the laminated vitrification was inferior to that of the first comparative example, and it was difficult to control in manufacturing.

An object of the present invention is to prevent a film forming an adhesive layer for constituting a laminated glass from being crushed or escaped by a local tightening force applied to the laminated glass mounting structure for holding the laminated glass by a metal fitting. It is an object of the present invention to provide a method for supporting a laminated glass in which local bending stress is prevented from being applied to the plate glass of the sandwiched portion and the workability is improved.
