Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a support structure for a glass screen using a composite rib having a small width in which a glass plate and a metal rib frame are compositely integrated.
[0002]
[Prior art]
Conventionally, for the purpose of daylighting, aesthetics, and the like, in the formation of a glass screen that forms a large opening by arranging large glass plates on the outer wall of the building, glass ribs are erected perpendicularly to each vertical side of the face glass plate. (Structural Sealing Glazing System) in which the face glass plate is bonded and supported by a structural sealing material on a metal back mullion provided on the indoor side of the face glass plate. Various methods such as a construction method have been adopted.
[0003]
The glass rib construction method using the rib glass includes a glass rib construction method (also referred to as a glass stabilizer construction method) in which a glass plate becomes independent, and a hanging rib construction method (also referred to as a suspension stabilizer construction method) in which an upper end of a glass plate is suspended and supported. The selection differs depending on the height of the opening area of the face glass, the thickness of the glass sheet, and the like. However, when the height of the face glass is as low as less than 6 m, the glass rib method is used, and the height of the face glass is 4.5 m. When the height is higher than the above, the hanging rib method is used (Non-Patent Document 1).
[0004]
Among the methods using the glass ribs, the rib glass method is a method of using a rib glass to support the deflection of the face glass by its own weight and the wind load applied to the face glass.
[0005]
For example, Japanese Patent Application Laid-Open No. H10-61069 describes, as a conventional technique, an example in which a rib glass is disposed at a butt portion on a vertical side of a face plate glass and bonded with a sealing material in FIGS. 1).
[0006]
In addition, a structural silicone method is described in which a face glass is bonded and supported by a silicone adhesive 3 having a predetermined thickness to a metal frame 2 provided on the indoor side of the face glass (Patent Document 2).

[Problems to be solved by the invention]
In the method described in Patent Document 1, the self-supporting construction method with a rib glass for supporting the glass rib by itself is widely used as a method for giving a transparent feeling to a glass opening, but has sufficient rigidity for a glass rib to be cubic. It is necessary to make the depth dimension (width dimension) of the glass rib large, and furthermore, to perform sealing bonding with the surface glass only at the thickness and width of the glass rib, a sufficient amount of bonding margin should be applied to the end face of the glass rib. There is a concern that it cannot be obtained and a large adhesive strength cannot be obtained.
[0009]
Further, the method described in Patent Document 2 is difficult to perform on-site bonding work because a metal frame made of an aluminum mold and the like and a glass plate are bonded by a dedicated bonding facility in a factory. Since it has to be bonded by equipment, the size of the side to which the glass plate is bonded is also limited, and it cannot cope with a large opening.
[0010]

A foam material is provided as a backup material 14.
[0019]
As shown in FIGS. 1 and 2, the periphery of such a strip-shaped glass plate 4 is covered by a channel-shaped glass gripping member 6 having a substantially U-shaped cross section from the upper structure to the lower support frame 11. The length corresponding to the vertical side is covered, and the strip-shaped glass plate 4 exposed from the opening surface of the glass gripping member 6 is directed in the direction facing the vertical joint between the face plate glasses 2, and the glass gripping member 6 A sealing material 9 made of silicone or the like is filled and bonded between the rectangular glass plate 4 surface exposed from the opening and the vertical edge of the face glass 2, and at the same time, the face glass 2 Sealing material was also filled in joints of the butt portions on the vertical sides.
[0020]
The adhesive width of the sealing material 9 provided between the strip-shaped glass plate 4 and the face plate glass 2 is slightly narrower than the opening width of the glass gripping member 6, and the sealing material 9 is extended to the tip of the opening of the glass gripping member 6. When the sealing material 9 is not filled, it is preferable that the adhesive force to the strip-shaped glass plate 4 when the sealing material 9 is deformed is not impaired. However, the sealing material 9 may be filled up to the entire width of the glass gripping member 6. good.
[0021]

[0023]
As shown in FIG. 1, the metal part 5 of the rib 3 is provided with a mounting member 7 having a U-shaped cross section and the same length as the glass gripping member 6 on the rear side of the glass gripping member 6 on the indoor side. The fixing member 7 is fixed by welding or the like, and the mounting member 7 is disposed so as to be back-to-back with the glass gripping member 6 such that a U-shaped opening is provided on the indoor side opposite to the glass gripping member 6. The metal plate 8 was inserted into the inside of the U-shaped portion of the mounting member 7, and fixed by screwing bolts and nuts (not shown).
[0024]
Next, the operation of the present invention will be described.
[0025]
As shown in FIGS. 1 and 2, the present invention is a composite rib (cube) 3 composed of the above-described strip-shaped glass plate 4 and a metal part 5 surrounding the periphery thereof. Acts as if it were a cubic, and it can make use of the rigidity of a metal cubic, so the overall width of the rib 3 can be smaller than a glass rib consisting only of a glass plate, and a slim shape In addition to the above, the glass screen 1 can be provided with an unprecedented design.
[0026]
When the rib 3 and the face glass 2 are bonded by filling with the sealing material 9, the cross section is formed so as to surround the periphery of the strip-shaped glass sheet 4 except for the central face of the face facing the face glass 2. Since the glass gripping member 6 in the shape of a substantially U-shaped channel (a channel steel having an opening in part) is covered, the sealing material 9 between the rib 3 and the face glass 2 is a glass gripping member having an opening. 6, the sealing material 9 is filled and bonded between the surface of the strip-shaped glass plate 4 exposed from the opening and the face glass 2, thereby preventing poor adhesion between the glass plate 2 and the metal rib 5. Can be.
[0027]
Further, the strip-shaped glass plate 4 was provided at a position along the vertical side where the face glass sheets 2 and 2 were attached to each other, and was disposed so as to be parallel to the face glass sheet 2. Further, the opening width of the opening of the glass gripping member 6 disposed so as to surround the rectangular glass plate 4 is smaller than the width of the rectangular glass plate 4 and the joint between the face glasses 2, 2. At least the same width or more than the width.
[0028]
As described above, the width of the bonding between the strip-shaped glass plate 4 and the sealing material 9 can be made wider than the joint width, and the bonding width for sealing and bonding the face plate glass 2 and the strip-shaped glass plate 4 is greatly increased. Therefore, the adhesive strength can be made stronger as compared with the conventional case where the rib glass is bonded to a width of about the plate thickness.
[0029]
Still further, the plate surface of the strip-shaped glass plate 4 is arranged so as to be parallel to the surface of the face plate glass 2, 2 when a load such as a wind pressure load is applied from an out-of-plane direction of the face plate glass 2. The force applied to the strip-shaped glass plate 4 can be deposited in the metal glass gripping metal 6, and the force for forcibly deforming the strip-shaped glass plate 4 is reduced.
[0030]
In particular, when the strip-shaped glass plate 4 is vertically divided into a plurality of sheets instead of a single sheet and is arranged in series with a cushioning material or the like, the divided glass plates 4, 4 Since the bending deformation applied to the strip-shaped glass plates 4, 4,... Is once cut, the force applied to each of the strip-shaped glass plates 4, 4,. Can be added even if
[0031]
The glass gripping member 6, the partition member 13, the mounting member 7, and the metal plate 8 are preferably made of a non-rusting metal such as stainless steel.
[0032]
As the sealing material 9 to be filled between the rectangular glass plate 4 and the face plate glass 2, it is preferable to use a high modulus elastic sealing material of a silicone sealing material.
[0033]
In addition, buffer sheets 15, 15 'provided between both sides of the strip-shaped glass plate 4 and the glass gripping member 6, and buffer members provided between the strip-shaped glass plates 4, 4,... Uses molded rubber such as EPDM rubber and chloroprene rubber.
[0034]
Further, as the backup material 14 provided between the strip-shaped glass plates 4, 4,... Which are divided and arranged in a line vertically, a foam material made of vinyl chloride was used.
[0035]
As described above, since the outer periphery of the rib 3 is made of a rigid metal, the width of the rib can be reduced by making use of the rigidity of the metal, and the inside of the rib 3 is formed into a strip-shaped glass plate 4. 4 is arranged so as to be parallel to the surface of the face glass 2, and the strip-shaped glass plate 4 and the face glass 2 are bonded by the sealing material 9, so that a large bonding width can be obtained and a large bonding can be achieved. Can maintain power.
[0036]
The face glass 2, 2,... And the ribs 3 are supported and fixed or suspended and fixed in the lower frame 11 and the upper frame 10 and the upper structure (not shown) connected to the structural body (not shown), respectively. ing.
[0037]
Further, when the upper frame 10 moves parallel to the surface of the face glass 2 due to interlayer displacement due to an earthquake or the like, the rib 3 is forcibly inclined by the upper frame 10 of the rib 3, and the face glass 2 is in contact with the rib 3. Due to the dimensional design of the sealing material 9 provided at the abutting portion, the face glass will not be damaged even if there is a misalignment with the rib 3 when interlayer displacement occurs.
[0038]
Further, since the strip-shaped glass plate 4 is surrounded by the rigid glass gripping member 6, it is in a protected state and does not break.
[0039]
Although the preferred embodiment has been described above, the present invention is not limited to this, and various applications can be considered.
[0040]
As shown in FIG. 7, a backup member 16 made of a foam material made of vinyl chloride is inserted into a gap between the rectangular glass plate 4 and the corner on the opening side of the glass gripping member 6 to insert the rectangular glass plate 4. Is fixed, and a portion surrounded by the backup portion 16 material, the strip-shaped glass plate 4 and the opening of the glass gripping member 6 is filled with a high modulus silicone sealant to form a seal portion 17. May be.
[0041]
The dimensions of typical parts of each part of the present invention are shown below.
[0042]
The dimensions of the divided strip-shaped glass plate 4 are as follows: plate width = 25 to 50 mm, plate thickness = 10 to 19 mm, length = 300 to 500 mm, and the sealing material 9 between the face plate glass 2 and the strip-shaped glass plate 4. When the bonding thickness of the sealing material 9 is within the opening of the glass gripping member 6 as shown in FIGS. 1 and 2, the bonding width of the sealing material 9 is 16 to 32 m. .
[0043]
The joint width of the face glass sheets 2 and 2 is 6 to 12 mm, and the overall dimension from the face glass 2 to the indoor end of the metal sheet material 5 is about 75 to 100 mm, which is a very small width rib. Can be.
[0044]
When the sealing material 9 is filled not only in the opening of the glass gripping member 6 as shown in FIG. 6 but also in the entire width of the glass gripping member 6, the bonding width of the sealing material 9 with the rib 3 is determined by the glass gripping. The size of the metal fitting 6 was 30 to 60 m.
[0045]
【The invention's effect】
As described above, since the outer periphery of the rib glass is made of a rigid metal, the width of the rib can be reduced by utilizing the rigidity of the metal, and the inside of the rib glass is formed into a rectangular glass plate. Since the surface is arranged so as to be parallel to the face plate glass and the strip-shaped glass plate and the face plate glass are bonded with a sealing material, a large bonding width by the sealing material can be obtained, and a large bonding force can be secured. In addition, it is possible to cope with deformation of the face plate glass due to a load from an out-of-plane direction.
[0046]
Further, the strip-shaped glass plate is cut and divided at a plurality of locations, and the partition member and a plurality of strip-shaped glass plates juxtaposed via a cushioning material or a backup material are cut in the middle. The force applied to the glass plate is small, and it is possible to cope with a larger load from the out-of-plane direction and to apply a force for greatly deforming the rectangular glass plate.
[0047]
Furthermore, it is usually difficult to bond metal ribs and face sheet glass with a sealing material at a building site, and it has been necessary to bond them with dedicated equipment at a factory. By mainly using a glass plate as the bonding part with the sealing material, bonding at the construction site became possible.
