【Example】
"First Embodiment"
FIG. 5 is a perspective view of the first embodiment showing the overall structure of the sheet glass construction of the present invention, in which a plurality of sheet glasses G are arranged so as to form a wall surface, and the sheet glass G is sandwiched. The holding member 4 is slidably connected to the suspension member 3 in a horizontal plane, and the suspension member 3 is slidably attached to the frame 5.
[0016]
Further, these upper and lower ends are fitted into an upper side frame 27 fixed to the frame 5 and a lower side frame 28 fixed to the frame (not shown), respectively. The part is sealed with a sealing material 20. 30 is a floor material.
[0017]
The suspension member 3 has a rod 1 having an external thread on the upper side. The rod 1 is loosely penetrated into a loose hole 26a (not shown) formed in the frame 5 and has a ball washer 23a and a spherical ring 21a. And is screwed to the frame 5 by a nut 15.
[0018]
Since the ball washer 23a and the spherical ring 21a are slidable, and the rod 1 passes through a loose hole 26a formed in the frame 5, the suspension member 3 is movable with respect to the frame 5. ing.
[0019]
1, 2, and 3 are a side sectional view, a front sectional view, and a perspective view, respectively, of a main part of the sheet glass construction of FIG.
[0020]
As shown in the figure, the upper edge of the plate glass G is held by the holding member 4 via the tapered members 14. The holding member 4 includes a horseshoe-shaped holding portion 2 and a forked connecting portion 7 fixed to an upper portion of the holding portion 2 and opening upward. The tapered members 14 and 14 have a shape that becomes thicker upward, and are adhered to both surfaces of the upper edge portion of the plate glass G with an epoxy-based or other appropriate adhesive.
[0021]
The holding portion 2 has, at its lower end, a protruding portion that protrudes inward from each other. The gap between the protruding portion and the protruding portion is such that the protruding portion contacts the surface of the tapered material 14 and the sheet glass G It is pinched so that it does not fall off.
[0022]
On the other hand, the suspension member 3 includes the rod 1, a connecting portion 8 fixed to a lower end of the rod 1, and a pin 10. The connecting portion 8 has a spherical bearing 9 slidable with respect to the main body of the connecting portion 8 below, and the bearing 9 has a through hole 17 having a size through which the pin 10 of the suspension member 3 is inserted. Is provided.
[0023]
The distance between the forked connection portions 7 is set to a size into which the bearing 9 is inserted.
[0024]
On both side surfaces of the forked connecting portion 7, through holes 17, 17 of a size through which the pin 10 is inserted are provided, and the bearing 9 of the connecting portion 8 of the suspension member 3 is provided between the both side surfaces of the forked connecting portion 7. Then, the pin 10 is inserted through one through hole 17 of the forked connecting portion, and inserted through the through hole 18 of the bearing and the other through hole 17 of the forked connecting portion. Reference numeral 11 denotes a retaining ring for preventing the pin 10 from falling off. The hanging member 3 and the holding member 4 thus connected are slidable with each other.
[0025]
The rod 1 of the suspension member 3 is provided with a male screw above it. The rod 1 has a loose hole 26a of the frame 5, a loose hole 25a of the ball washer 23a fixed to the upper portion of the frame 5 by welding, and a spherical ring 21a slidably mounted on the ball washer 23a. After passing through the through hole, the nut 15 is screwed into the male screw of the rod 1.
[0026]
The lower portion of the spherical ring 21a has a spherical surface, and a recess having the same shape as the spherical surface is formed in the ball washer 23a. That is, the first sliding surface 24a that allows the spherical ring 21a to slide with respect to the ball washer 23a is formed. The length of the arrow P1 is the radius of curvature of the first sliding surface 24a, and the starting point is the center of the curved surface. The surface of the spherical ring 21a is subjected to a solid lubricant treatment 22 using grease or the like.
[0027]
In this embodiment, the radius of curvature (the length of the arrow P1) is smaller than that of the embodiment shown in FIGS. 8 and 9 described later, so that the spherical ring 21a slides with respect to the ball washer 23a. It is excellent in that it can easily return to its original position later. That is, the smaller the radius of curvature, the better. On the other hand, the lower limit of the radius of curvature is determined by the diameter of the rod 1 and a design angle at which the rod 1 needs to be inclined with respect to the skeleton 5 in response to an earthquake or the like.
[0028]
In this way, the glass sheet G is slidably hung on the frame 5 using the holding member 4 and the hanger member 3. In addition, since there are two operation center points that are movable in the front-rear and left-right directions at the upper and lower ends of the suspension member 3, the flexibility of the sheet glass G with respect to the frame 5 is high.
[0029]
Therefore, even if an interlayer displacement occurs in the frame due to an earthquake or the like, a force for deforming the sheet glass G is unlikely to be generated, and the possibility of breakage of the sheet glass G is extremely reduced. As the material of the holding member 4 and the hanging member 3, a metal is preferable in terms of excellent strength, and among them, ordinary steel is particularly preferable in terms of price.
[0030]
Such a construction body is constructed as follows. The clamping member 4 and the suspension member 3 are connected in advance, and the rod 1 is inserted into the loose hole 26a of the frame 5, the loose hole 25a of the ball washer 23a fixed to the upper portion of the frame 5, and the through hole of the spherical ring 21a. Insert. Next, the nut 15 is screwed into the male screw of the rod 1 from above, and the holding member 4 is hung on the frame. Instead of this, the suspension member 3 may be first suspended on the skeleton, and then the suspension member 3 and the clamping member 4 may be connected using the pin 10 and the retaining ring 11.
[0031]
On the other hand, the taper material 14 is bonded to both surfaces of the upper edge portion of the sheet glass G with an adhesive such as an epoxy type. Next, the sheet glass G is lifted, the portion of the tapered material of the sheet glass is inserted into the gap between the protruding portions of the holding section 2, and the sheet glass G is held by the holding section 2 and hung on the frame 1. Next, a sealing material 29 (shown in FIG. 5) such as silicone is injected into a gap between the adjacent plate glasses.
[0032]
Thus, the sheet glass construction of the present invention is obtained. The size of the sheet glass G is not particularly limited, and for example, those having a height of about 2 to 20 m and a width of about 1 to 5 m are used.
[0033]
Unlike the present embodiment, a connecting portion is provided on the upper portion of the holding portion 2, a slidable spherical bearing is provided on the body of the connecting portion, and a forked connecting portion that opens below the hanging member is provided. It is also possible to insert a main body and a bearing of the connecting portion between the forked connecting portions, and connect these with a pin and a retaining ring.
[0034]
FIG. 4 is a side sectional view of a main part of another embodiment in which the portion A of the sheet glass construction of FIG. 1 is changed. In this construction, the taper members 14 are bonded to both surfaces of the upper edge of the sheet glass G. That the holding portion 2 in contact with the tapered member has a horseshoe shape, that a male screw is provided on the rod 1 of the suspension member 3 and that a nut 15 is screwed thereto, and that the rod 1 is The loose hole 26a of the frame 5 and the hole 25a of the ball washer 23a fixed to the upper portion of the frame 5 are inserted into the loose hole 25a and suspended by the spherical ring 21a as in FIG.
[0035]
In the construction shown in FIG. 4, the grip connection portion 6 of the suspension member 3 has a spherical inner surface that wraps the bearing 9 of the connection portion 8 of the holding member 4. The connection portion 8 of the holding member 4 and the grip connection portion 6 of the suspension member are slidably connected to each other.
[0036]
FIG. 6 is a side sectional view of an essential part for explaining the operation of the sheet glass construction of FIG. 5, and shows a case where a force is applied to the upper and lower sides of the skeleton by an earthquake or the like in directions of E1 and E2, and interlayer displacement occurs in the skeleton. . In this case, an external force that normally causes an out-of-plane deformation acts on the sheet glass G. However, as shown in the figure, the connecting portion 8 fixed to the lower end of the hanging member 3 is sandwiched by the forked connecting portion 7 and the bearing 9. The upper end of the suspending member 3 is similarly slidably suspended on the skeleton 5 by a spherical ring 21a, a ball washer 23a, and the like. For this reason, interlayer displacement is absorbed at the upper and lower ends of the suspending member, and the generation of an external force that causes the sheet glass G to undergo out-of-plane deformation is reduced.
[0037]
FIG. 7 is a front cross-sectional view of a main part illustrating the operation of the sheet glass construction of FIG. 5, showing a case where forces are applied in the directions of F1 and F2 above and below the skeleton due to an earthquake or the like, and interlayer displacement occurs in the skeleton. . In this case, usually, an external force acting to cause in-plane deformation of the glass sheet G acts, but in the same manner as described above, interlayer displacement is absorbed at the upper and lower ends of the suspension member, and the in-plane deformation of the glass sheet G is caused. Is reduced.
[0038]

FIG. 8 is a side sectional view of a main part of a second embodiment of the sheet glass construction of the present invention, and FIG. 9 is a front sectional view of a main part of the sheet glass construction of FIG. In this example, the spherical ring 21a is changed to a spherical ring 21b, and the ball washer 23a is changed to a ball washer 23b, and the other components are the same.
[0039]
The lower portion of the spherical ring 21b has a slightly larger diameter spherical surface, and the ball washer 23b has a concave portion having a curved surface having the same diameter as the slightly larger diameter spherical surface. That is, the first sliding surface 24b that allows the spherical ring 21b to slide with respect to the ball washer 23b is formed. The length of the arrow Q1 is the radius of curvature of the first sliding surface 24b, and the starting point is the center of the curved surface. The surface of the spherical ring 21b is subjected to a solid lubricant treatment 22.
[0040]
"Third embodiment"

It is a perspective view and a principal part component configuration diagram.
[0041]
In this construction, the tapered members 14 and 14 are adhered to both surfaces of the upper edge of the sheet glass G, the holding portion 2 in contact with the tapered member 14 is horseshoe-shaped, 1, 2, and 3 is that the connecting portion 8 fixed to the lower end of the member is slidable with respect to the holding member 4 by the forked connecting portion 7 and the bearing 9.
[0042]
The rod 1 of the suspension member 3 is provided with a male screw above the rod 1, and a nut 15 is screwed into the male screw. The rod 1 has a loose hole 26c of the frame 5, a loose hole 25c of a base 38a fixed to the upper portion of the frame 5 by welding, and a through hole of a slide 32a slidably mounted on the base 38a. , The nut 15 is screwed into the male screw of the rod 1.
[0043]
The sliding body 32a is composed of a spherical ring 21c and a sliding body 33a. The spherical ring 21c has a lower surface having a spherical surface, and the sliding body 33a has a recess having the same shape as the spherical surface. That is, the first sliding surface 24c that enables the spherical ring 21c to slide with respect to the sliding body 33a is formed. The length of the arrow R1 is the radius of curvature of the first sliding surface 24c, and the starting point is the center of the curved surface. The surface of the spherical ring 21c is subjected to a solid lubricant treatment 22 (not shown).
[0044]
Shafts 35a, 35a are provided on both sides of the slide body 33a, and rollers 34a, 34a are attached by retaining rings 37a, 37a via low friction fluororesin packings 36a, 36a.
[0045]
The base 38a has a recess in addition to the loose hole 25c. That is, the second sliding surface 39a that allows the rollers 34a, 34a to slide is formed. The length of the arrow R2 is the radius of curvature of the second sliding surface 39a, and the starting point is the center of the curved surface. This radius of curvature is much larger than the radius of the roller 34a. When the roller 34a slides on the second sliding surface 39a, the sliding body 32a moves in the T direction and also moves in the upward direction.
[0046]
"Fourth embodiment"
FIG. 14 is a side sectional view of a main part of a fourth embodiment of the sheet glass construction of the present invention, and FIG. 15 is a front sectional view of a main part of the sheet glass construction of FIG. FIGS. 14 and 15 are obtained by changing the sliding body 32a to the sliding body 32b and changing the base 38a to the base 38b in FIGS. 10 and 11, but the sliding body 32a and the sliding body 32b are substantially The difference is that the radius of curvature of the second sliding surface of the base 38a is reduced. The length of the arrow S1 is the radius of curvature of the second sliding surface 39b, and the starting point is the center of the curved surface. This radius of curvature is slightly larger than the radius of the roller 34b. When the roller 34b slides on the second sliding surface 39b, the sliding body 32b moves in the U direction and moves in the upward direction.
[0047]
In this embodiment, the radius of curvature (the length of the arrow S1) is smaller than that of the embodiment shown in FIGS. 10 and 11 described above, so that the sliding body 32b slides against the base 38b. It is excellent in that it can easily return to its original position. That is, the smaller the radius of curvature, the better. On the other hand, the lower limit of the radius of curvature is determined by the diameter of the rod 1 and a design angle at which the rod 1 needs to be inclined with respect to the skeleton 5 in response to an earthquake or the like.
[0048]
【The invention's effect】
