Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a glass fixture for fixing a large-sized glass as an exterior material to a support structure. 2. Description of the Related Art Conventional methods for mounting glass as an exterior material are roughly classified into the following four types. (1) Sash method (2) SSG (Structural Sealant Glazing) method (3) Hanging re-glass method (4) DPG (Dot Point Glazing) method [0003] Of these, the sash method (1) above is within the framework A method of fitting glass, which is generally used for relatively small glass surfaces and is a proven method. However, recently, there has been an increasing demand for using a large glass surface or erasing a sash. The methods used for these requirements are the above-mentioned methods (2) to (4). The SSG method described in (2) above is a method of making the sash frame invisible from the outside, and the hanging glass method (3) and the DPG method are methods using no sash. The SSG method is a method in which glass is directly adhered to a support structure with a structural seal having high adhesiveness, and a continuous glass surface without a seam can be obtained. However, since this method relies on the reliability of the seal, in Japan, where the wind load is large, it is rare to bond four rounds of glass. For this reason, at present, the continuity of the glass surface, which is an original advantage, cannot be fully utilized. In addition, there are many restrictions in adopting this method, such as the need to set a large safety factor at the design stage, and the necessity of a meticulous maintenance management system because the adhesion durability is not completely reliable. There is a problem that. [0005] Next, in the above-mentioned hanging glass method, a glass plate is hung from an upper frame, and glass ribs (rib glass) are usually provided in the vertical direction to reinforce the glass surface. While this method allows for large glass surfaces, the upper frame that receives the suspended glass tends to be large. In addition, there are cases where design restrictions arise in terms of securing the reliability of the bonding method between the glass and the rib and stiffening the vertical rib under a load. On the other hand, the above-mentioned DPG method is a method of supporting a glass point, making holes in the four corners of the tempered glass, and connecting the glass to a separately provided support structure through the holes.
That is, the binding member 50 as shown in FIG. 17 is used as a basic member, and the binding member 50 is inserted through a metal glass liner 53 into a mounting hole 52 formed near a corner of a glass 51 having a predetermined size. The head 54 is fixed in advance. Then, as shown in FIG. 18, for example, a pair of glasses 51, 51 on the outer peripheral portion of the entire exterior glass surface.
As shown in FIG. 17, in the case of the joint portion E between the end portions, a connecting member 60 for two holes that interconnects the pair of fastening members 50, 50 is used. The fitting holes 62 formed at both ends are inserted into the bolt portions 55 of the corresponding binding members 50, respectively, and both are fastened and fixed with the nuts 56. Also, the ends of the rod-shaped connecting portions 63 of the connecting members are
It is adapted to be appropriately fixed to the support member 70. As shown in FIG. 18, at the outer peripheral corner F of the entire exterior glass surface, one binding member 50 and a corresponding one-hole connecting member are used. Joint G between the four pieces of glass 51 at the center of the whole
In this case, the glass 51 is fixed using four binding members 50 and corresponding four-hole connecting members. This method has the advantage that a large glass surface can be realized. However, this method has a problem that the strength of the glass 51 at the hole is lower than the original strength of the glass because the cross-section is lost due to the hole. are doing. In particular, the number of components such as the binding members 50 and the like at the joints G and E on the exterior glass surface increases, and the construction is complicated, and there is a problem in the workability. Further, since there is no clearance in the binding member 50, the metal glass liner 53, and the connecting member 60 that can absorb a manufacturing error, it is necessary to ensure a high level of accuracy in drilling the glass 51, and material and manufacturing costs are reduced. There was a problem of becoming high. [0010] The present invention solves the above-mentioned conventional problems, eliminates the need for perforating glass, eliminates cross-sectional defects, improves manufacturability, and performs glass binding at a single point to provide a fixture. It is an object of the present invention to provide a novel glass fixture structure capable of improving the workability by reducing the number of pieces. According to the present invention, there is provided a glass fixture for fixing glass as an exterior material to a support structure, comprising: an inner sandwiching plate; An outer holding plate, a packing plate, and a coupling bolt, wherein the inner holding plate is fixed to the predetermined support structure, and the inner holding plate is in contact with each corner of the glass from the inside, and The sandwiching plate is abutted on each corner of the glass from the outside, and the packing plate is interposed on the inside and outside of each corner of the four glass pieces disposed opposite to each other, and A connecting bolt is inserted into a mounting hole formed through a substantially central portion of the holding plate, and the connecting bolt is screwed into a female screw portion formed at a substantially central portion of the inner holding plate, and tightened by screwing. Inside corner It is characterized in that it is sandwiched between a side sandwiching plate and an outer sandwiching plate and fixed by supporting pressure. It is preferable that a rib is formed upright on the contact surface of the inner sandwiching plate or the outer sandwiching plate with the glass along joints between the four glass plates. desirable. The outer shape of the inner sandwiching plate and the outer sandwiching plate can be appropriately formed into a rectangle, a circle or a super-ellipse. Further, the packing plate is formed with a fitting hole into which a corner portion of the glass can be fitted, and an inner interposed portion and an outer interposed portion of the glass are integrally formed. It is desirable to have a configuration. Further, as the support structure, any one of a single material, a truss, a cable girter, and a single or double cable net can be applied.

The inner sandwiching plate 2 can be fixedly joined to the steel pipe 12.
The connecting plate 10 has a mechanism capable of transmitting a moment in the vertical direction so that a bending moment caused by the weight of the glass caused by the eccentricity of the glass 6 and the steel pipe 12 as a support structure is not generated on the glass surface. The outer sandwiching plate 3 comes into contact with each corner 6a of the glass 6 from the outside, and a mounting hole 16 for the coupling bolt 5 also penetrates through the center of the outer sandwiching plate 3. The coupling bolt 5 can be screwed. Also, on the outer surface of the outer sandwiching plate 3, a rib 17 is formed in an annular shape around the mounting hole 16, and is formed radially from the annular portion to form a cross shape. Therefore, in this embodiment, as shown in FIG. 5, the connecting bolt 5 is screwed into the mounting hole 16 of the outer holding plate 3, and the tip of the connecting bolt 5 is screwed into the female screw portion 9 of the inner holding plate 2. Then, each corner 6a of the glass 6 is held between the inner sandwiching plate 2 and the outer sandwiching plate 3, and can be fixed by supporting pressure. That is, in the present embodiment, each corner 6a of the four glasses 6 can be so-called point-supported by one glass fixture. In addition, the glass fixture 1

It functions as a cushioning material between the glass 6 and the inner sandwiching plate 2 and the outer sandwiching plate 3, equalizes the supporting pressure of the sandwiching plates 2, 3, and reduces the local stress generated when the glass 6 is deformed. Has a function to reduce. In this embodiment, the inner packing plate 4
a is formed in a substantially rectangular plate shape having a size corresponding to the inner sandwiching plate 2 as shown in FIG. 3, and a through hole 18 having a shape corresponding to the rib 8 of the inner sandwiching plate 2 is formed in the center. A gasket 19 is fixed around the through hole with a constant width and a thickness equal to the thickness of the glass 6. Therefore, in the central part of the glass fixture 1, the periphery of the glass 6 is pressed against and tightly contacted with the gasket 19, and the joint is sealed in a watertight manner. In this embodiment, the outer packing plate 4b is formed in a substantially rectangular shape having a size corresponding to the outer sandwiching plate 3 as shown in FIG. A through hole 20 having a shape corresponding to is formed. In this embodiment, the inner packing plate 4a and the outer packing plate 4b are both formed of an elastic body made of a synthetic rubber such as neoprene or a synthetic resin, but other materials having the same performance should be used. Is of course possible. The procedure for installing the glass fixture 1 of the present embodiment having the above-described configuration is as follows. (1) The inner packing plate 4a and the outer packing plate 4b are previously fitted between the inner holding plate 2 and the outer holding plate 3, and the connecting bolts 5 are adjusted to adjust the inner holding plate 2 and the outer holding plate. By fixing the connecting plate 10 to the gusset plate 13 in a state where the space between the connecting plate 3 and the
The glass fixture 1 is attached to a steel pipe 12 as a support structure. (2) Each glass corner 6a is inserted into the gap between the inner sandwiching plate 2 and the outer sandwiching plate 3 of the glass fixture 1 as shown in the figure. (3) Tighten the connecting bolt 5 to fix each glass 6. (4) The joints 7 between the glasses 6 are sealed with a suitable sealing material (not shown). Next, in the above embodiment, an example is shown in which a single material steel pipe 12 is employed as the support structure. However, the steel tube 12 can be attached to any other suitable single material such as an H-beam or a truss. Further, it is also possible to use a grid-like cable net 20 as shown in FIG.
A first fixing member 21 is provided integrally with the second fixing member 22, one of the cable nets 20 is sandwiched between the first fixing member 21 and the second fixing member 22.
With the other cable net 20 sandwiched between the fixing member 22 and the third fixing member 23, a fixing bolt 25 is screwed into a mounting hole 24 formed at a corresponding position of each fixing member, and tightened by tightening. The glass fixture 1 can be fixed to the cable net 20 as the above. FIG. 9 is an arrow view from the inside of FIG. Further, as shown in FIG. 10, it is also possible to arrange the cable nets 20 in a lattice shape in a double manner. Also, as shown in FIGS. 11 and 12, the configuration of the outer sandwiching plate 3 may be changed so that the ribs 17 are omitted and the connecting bolt 5 may be a bolt with a head. Further, as shown in FIG. 13, a cable girder 26 can be used, the cable net 21 shown in FIGS. 11 and 12 can be used, and a concrete wall surface or the like can be used as a support structure. Further, the present invention is not limited to the above embodiment, and the outer shapes of the inner sandwiching plate 2 and the outer sandwiching plate 3 are as follows.
In addition to the rectangular shape as in the above embodiment, it can be appropriately formed into a circular shape, a rectangular shape or a super-elliptical shape as shown in FIGS. 14 to 16. In short, the glass corner portion 6 a is securely tightened, Any shape may be used as long as the glass 6 can be fixed by the supporting pressure. Further, the material of the sandwiching plates 2 and 3 may be an elastic material such as rubber in addition to metals such as steel, aluminum, and casting having high bending rigidity. Further, the packing plate 4 may be formed by integrating the inner packing plate 4a and the outer packing plate 4b to form a fitting hole in which a corner of the glass 6 can be fitted. Further, in the above-described embodiment, the means for connecting the bolts with the connecting plate 10 has been exemplified as the structure of the attachment portion to the support structure. However, other than this, any other joining method capable of transmitting a vertical bending moment, such as welding. Can be adopted. The material of the packing plate 4 can be appropriately adopted as long as it has a function of a buffer between the glass 6 and the sandwiching plates 2 and 3, such as neoprene rubber. Further, the shape of the packing plate 4 is not one in which the inner side and the outer side are integrated as in the above embodiment, but may be a sheet-like one in which the inner side and the outer side are separated. The size and wall thickness of each component are also
It goes without saying that various modifications can be made without departing from the gist of the present invention, for example, it can be appropriately changed according to design conditions. The present invention is configured as described above,
The following effects can be obtained. (1) A large seamless glass surface can be realized. (2) Each corner of the four glasses can be point-supported with one glass fixture, so the number of fixtures is small, and the glass can be attached only by tightening bolts, so construction is easy. . (3) Since it is not necessary to form a hole in the glass, the strength of the glass is not degraded due to a cross-sectional defect, and the productivity can be significantly improved. (4) It is a glass holding type using only a glass fixture, and since it does not use a structural seal, it has high reliability and excellent durability. (5) Since the mounting part to the support structure can transmit the bending moment in the vertical direction, a moment is generated in the glass when the load is constantly applied, and the safety is high. (6) The applicable form of the support structure has a wide range of applications, including single materials, trusses, cable nets, and cable girder. (7) If the packing plate has a shape in which the inner side and the outer side are integrated, mounting on the corner of the glass becomes easy, and workability is improved.
