Description of the Related Art A structure in which a hole is formed in a reinforced plate glass or a semi-reinforced plate glass and supported by a through-bolt-shaped bracket does not need to be provided with a sash material on the wall surface, and thus has a very high transparency. And at the entrance hall,
There is a tendency to be adopted more. In the present structure, the external force such as the own weight of the sheet glass and wind pressure is supported by the metal fittings attached to the holes of the sheet glass, so that the strength of the sheet glass is restricted. Therefore, as the sheet glass, tempered sheet glass or semi-tempered sheet glass having a smaller residual stress value than the tempered sheet glass is used. However, tempered glass sheets are
When the balance of the internal stress is lost, there is a drawback that the internal stress is broken. [0003] Therefore, as a measure to prevent scattering in the event of breakage, a measure of sticking a film or the like or using laminated glass is often taken. That is, the laminated glass has high scattering prevention performance. In a configuration in which a through-hole is provided in a laminated glass and a supporting bracket is attached, a method of countersinking a plate glass on a front side and a plate glass on a back side as a stupid hole is generally a method of absorbing an error generated in a bonding process. [0004] However, this method has the following problems. -Decrease in watertightness: It is difficult to sufficiently fill the sealant around the stupid hole, so that the watertightness tends to decrease. -Deterioration of appearance characteristics: Since perforations are formed in the sheet glass on the front side, the reflection image or the like is interrupted at the site, and the appearance characteristics are degraded. -High processing cost. SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned disadvantages of the prior art.
Low cost, excellent watertightness, no support fittings appear on the glass surface on the front side, and by using various plate glasses and interlayer films, with the aim of providing a laminated glass support structure with excellent design properties I have. According to the present invention, a through-hole is provided in one of the strengthened glass sheets of the laminated glass in which at least one of the glass sheets is a strengthened glass sheet, and the through-hole is provided on the intermediate film side of the through-hole. A countersunk hole is provided, a supporting bracket is attached using the countersunk hole, and a laminated glass is attached to the skeleton by attaching the supporting bracket to the skeleton.
A support structure for laminated glass, which is covered with the other plate glass via an intermediate film , wherein a support fitting attached to the countersunk hole portion has a receiving portion having a hemispherical concave portion, and a receiving portion having a hemispherical concave portion. A ball portion, and the ball portion can slightly rotate within the receiving portion.
Provides a support structure for laminated glass, which is in contact with the interlayer film through the receiving portion . Hereinafter, an embodiment of the present invention will be described. FIG. 1 is a sectional view of a support structure for a laminated glass of the present invention. FIG. 2 is a partially enlarged cross-sectional view of the support structure of FIG. As shown in FIG. 1, a support 2 is attached to the periphery of the laminated glass 1. By attaching the support fitting 2 to the frame 3, a plurality of laminated glasses 1 are mounted to the frame 3, and the outer surface thereof forms a continuous plane. In the laminated glass 1, a reinforced plate glass 6 and a plate glass 7 are bonded by an interlayer film 8 of polyvinyl butyral. This one tempered glass sheet 6 has
A through hole 9 to which the support fitting 2 is attached is provided, and a countersunk hole portion 10 which is formed by countersinking toward the intermediate film 8 is provided on the side of the through hole 9 toward the intermediate film 8. The support fitting 2 is attached to the countersunk hole 10 via a liner 11. This support bracket 2
Has a receiving portion 12 having a hemispherical concave portion, and a ball portion 13 housed in the concave portion of the receiving portion 12. Also, ball part
Reference numeral 13 is in contact with the intermediate film 8 via the receiving portion 12. Receiving part 1
In the vicinity of one end of 2, the tempered glass sheet 6 projects in the outer peripheral direction.
A protrusion 14 is provided for engaging with the countersink hole 10 of the first embodiment. A screw for screwing the nut 15 is provided near the other end of the receiving portion 12. The receiving portion 12 is fixed to the reinforced sheet glass 6 by the protrusion 14 and the nut 15. The ball portion 13 can slightly rotate around the point C in the receiving portion 12, and is generated in the countersunk portion when the laminated glass 1 is deformed by wind pressure or the like. Relieve stress concentration. Further, one end of the support fitting 2 is covered with another sheet glass 7 via the intermediate film 8 and is not exposed to the surface. As the sheet glass 7, a tempered sheet glass, a semi-tempered sheet glass, or a sheet glass that is not reinforced at all is used. Further, heat-absorbing glass, heat-ray reflecting glass, and various surface-treated glasses are also used as the sheet glass 7. The thickness of the reinforced sheet glass 6 is 6 to 15
mm and the thickness of the sheet glass 7 are practically about 12 to 19 mm. In addition, receiving part 12, ball part 1
3. As the material of the liner 11, stainless steel and aluminum are practical. Such laminated glass is manufactured, for example, as shown in FIG. That is, first, a through hole 9 having a countersunk hole portion 10
To form Next, the support fitting 2 is inserted from the countersunk hole 10 side of the through hole 9 via the liner 11. Next, a nut 15 is attached to the support 2 from the opposite surface of the tempered glass sheet 6 via a washer 16 and an O-ring 17. Next, the nut 15 is connected to the receiving portion 1 of the support fitting 2.
2 is screwed into the screw provided on the outer peripheral portion. Next, although omitted in FIG. 3, a laminated glass is manufactured by bonding another plate glass to the surface of the strengthened plate glass 6 where the countersink portion 10 is provided with an intermediate film. The laminated glass is directly or indirectly attached to the frame 3 using a screw 18 provided at the tip of the ball portion 13. In the present invention, the glass sheet 7 on the front side covers the support fitting 2 and does not lower the design property of the support fitting like the conventional perforated tempered glass sheet. Also, the watertightness is not reduced. Since the sheet glass 7 on the front side has a small load on strength, unstrengthened float glass can be used. Since there is no drilling, the cost is low. Depending on design requirements, a heat ray reflective glass or a heat ray absorbing glass may be used. Alternatively, frosted glass can be used.
Furthermore, decorative laminated glass using a patterned film, punched metal, or the like for the intermediate film portion can also be used. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of the present invention, about 2 m × 2 m × 12
A laminated glass reinforced with mm was produced. That is, countersinking was performed on one of the strengthened glass sheets, a support metal was set, and the laminated glass was strengthened by processing with the other glass sheet. This was used as a decorative material for a steel frame. The other sheet glass, that is, the sheet glass on the front side, is a non-strengthened frosted glass having a thickness of 5 mm and subjected to sandblasting, and has an effect of covering the inner steel frame. It has the feel of a glass material, and no metal members such as sashes appear on the surface at all, making it possible to show a design like a lump of glass. Further, as another example, a trial production using a heat ray reflective glass as the other sheet glass was also performed, and its excellent design property was confirmed. According to the present invention, it is possible to obtain a laminated glass support structure having a good design. Since the front side glass sheet may be unstrengthened float glass, various designs are possible. Since the sheet glass on the front side does not have a hole, there is no loss of design. Also, the watertightness is not impaired. Even when this glass sheet breaks when non-strengthened float glass is used on the front side, the strengthened glass sheet on the back side is not broken.
