[0002]
[Prior art]
Conventionally, for the purpose of daylighting, aesthetics, etc., in the formation of a glass screen that forms a large opening by juxtaposing a large plate glass on the outer wall of a building, glass ribs are erected so as to be orthogonal to the vertical sides of the surface glass plate. The glass rib construction method that adheres with a sealing material and supports the surface glass plate, and the SSG (Structural Sealant Glazing System) that adheres and supports the surface glass plate to the metal back mullion provided on the indoor side of the surface glass plate with the structural sealing material ) Various methods such as construction methods have been adopted.
[0003]
The glass rib construction method using the rib glass includes a glass rib construction method for self-supporting a glass plate (also referred to as a glass stabilizer construction method) and a hanging rib construction method for supporting the glass plate by suspending the upper end thereof (also referred to as a hanging stabilizer construction method). The selection differs depending on the height of the opening area of the surface glass, the thickness of the glass plate, etc., but when the surface glass is generally less than 6 m in height, the glass rib method is used, and the height of the surface glass is 4.5 m. If it becomes high as mentioned above, the suspension rib construction method is used (nonpatent literature 1).
[0004]
Among the construction methods using the glass rib, the rib glass construction method is a construction method using the rib glass to support the bending due to the weight of the face plate glass and the wind load applied to the face plate glass.

The metal plate 8 was inserted inside 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 (orientation) 3 composed of a strip-shaped glass plate 4 and a metal portion 5 surrounding the periphery, as described above. Since it works as if it is a vertical and can take advantage of the rigidity of the metal vertical, the overall width of the rib 3 is smaller than that of a glass rib consisting only of a glass plate. In addition, it is possible to make the glass screen 1 have an unprecedented design.
[0026]
In addition, when the rib 3 and the face plate glass 2 are bonded together by filling the sealing material 9, the cross section has a cross-section so as to surround the periphery of the strip-like glass plate 4 except for the center face portion of the surface facing the face plate glass 2. Since the glass gripping member 6 in the shape of a substantially U-shaped channel (a grooved steel with an opening in a part) is covered, the sealing material 9 between the rib 3 and the face plate glass 2 is a glass gripping member having an opening. 6 to prevent the poor adhesion between the glass plate 2 and the metal rib 5 by filling and bonding the sealing material 9 between the face of the strip-shaped glass plate 4 exposed from the opening and the face plate glass 2. Can do.
[0027]
Further, the strip-shaped glass plate 4 was provided at a position along the vertical side of the face plate glass 2, 2 so as to be parallel to the face plate glass 2. The opening width of the glass gripping member 6 disposed so as to surround the strip-shaped glass plate 4 is narrower than the width of the strip-shaped glass plate 4 and the joint between the surface glasses 2 and 2. The width is at least equal to the width.
[0028]
In this way, the width of 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, it is possible to make the adhesive force stronger than in the case of bonding to a width approximately equal to the plate thickness of the conventional rib glass.
[0029]
Furthermore, the plate surface of the strip-shaped glass plate 4 is arranged so as to be parallel to the surfaces of the face plate glasses 2 and 2 when a load such as a wind pressure load is applied from the 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 divided into a plurality of pieces instead of a single plate in the vertical direction and arranged in series with a buffer material or the like, the strip-shaped glass plates 4, 4 are divided at the divided portions. Since the bending deformation applied to the strip glass plates 4, 4,... Is reduced, the force applied to the strip glass plates 4, 4,. Even if is added, it can respond.
[0031]
As the glass gripping member 6, the partition member 13, the mounting member 7, and the metal plate material 8, a metal that does not rust such as stainless steel is desirable.
[0032]
As the sealing material 9 filled between the strip-shaped glass plate 4 and the face plate glass 2, it is preferable to use a high-modulus elastic sealing material of a silicone-based sealing material.
[0033]
Further, buffer sheets 15 and 15 ′ provided between both surfaces of the strip-shaped glass plate 4 and the glass gripping member 6, and buffer materials provided between the strip-shaped glass plates 4, 4. Uses molded rubber such as EPDM rubber or 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 in the vertical direction, a foam material made of vinyl chloride was used.
[0035]
Thus, since the outer periphery of the rib 3 is made of a rigid metal, the width of the rib can be narrowed by making use of the rigidity of the metal, the inside is a strip-shaped glass plate 4, and the strip-shaped glass plate is further formed. 4 is arranged so as to be parallel to the surface of the face plate glass 2, and the strip-like glass plate 4 and the face plate glass 2 are bonded by the sealing material 9, so that the bonding width can be increased and the large bonding is achieved. You can maintain power.
[0036]
The face plate glasses 2, 2,..., And the ribs 3 are supported and fixed in a structural frame (not shown) and a lower frame 11 connected thereto, and an upper frame 10 and an upper structure (not shown), or are suspended and fixed. ing.
[0037]
Further, when the upper frame 10 is moved parallel to the surface of the face plate glass 2 due to an 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 plate glass 2 is separated from the rib 3. Due to the dimensional design of the sealing material 9 provided at the butting portion, even if there is a misalignment with the rib 3 when an interlayer displacement occurs, the face glass is not damaged.
[0038]
Further, the strip-shaped glass plate 4 is surrounded by the rigid glass gripping member 6 and thus is protected and is not damaged.
[0039]
The preferred embodiment has been described above, but the present invention is not limited to this, and various applications can be considered.
[0040]
As shown in FIG. 7, the strip-shaped glass plate 4 is formed by inserting a backup member 16 made of a vinyl chloride foam material into the gap between the corners on the opening side of the strip-shaped glass plate 4 and the glass gripping member 6. Further, the portion surrounded by the back-up portion 16 material, the strip-shaped glass plate 4 and the opening portion of the glass gripping member 6 is filled with a high modulus silicone sealant to form a seal portion 17. May be.
[0041]
The dimension of a typical part is shown below about each part of this invention.
[0042]
The dimensions of the divided strip-shaped glass plate 4 are: plate width = 25-50 mm, plate thickness = 10-19 mm, length = 300-500 mm, and the sealing material 9 between the face plate glass 2 and the strip-shaped glass plate 4. When the adhesive thickness is 10 to 15 mm and the adhesive width range of the sealing material 9 is within the opening of the glass gripping member 6 as shown in FIGS. 1 and 2, the adhesive width of the sealing material 9 is 16 to 32 m. .
[0043]
Also, the joint width of the face plate glasses 2 and 2 attached to each other is 6 to 12 mm, and the overall dimension from the face plate glass 2 to the front end of the metal plate 5 on the indoor side is about 75 to 100 mm, and the rib is extremely small. Can do.
[0044]
In the case where 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 made small by taking advantage of the rigidity of the metal, and the inside is a strip-shaped glass plate, and further the strip-shaped glass plate Since the surface is arranged so as to be parallel to the face plate glass and the strip-like glass plate and the face plate glass are bonded with a sealing material, the bonding width by the sealing material can be increased, and a large adhesive force can be secured. It is possible to cope with deformation due to a load from the out-of-plane direction of the face plate glass.
[0046]
Further, since the strip-shaped glass plate is cut and divided at a plurality of locations, and the plurality of strip-shaped glass plates arranged in parallel via the partition member and the buffer material or the backup material are cut in the middle, each strip The force applied to the glass plate can be reduced, and even when a force is applied to apply a larger load from the out-of-plane direction and greatly deform the strip-shaped glass plate, it can be dealt with.
[0047]
In addition, it is usually difficult to bond metal ribs and face plate glass with a sealing material at the construction site, and it was necessary to bond them with dedicated equipment at the factory. Adhesion construction at the construction site became possible by using the glass plate as the adhesive part of the sealant.
