Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a glass plate on a closed glass window. 2. Description of the Related Art The following are conventionally known structures for mounting a glass plate. First, a sash bar is fixed to a support member on the indoor side, a glass plate is fitted into the groove of the sash bar, and a bead or a sealing material is interposed between the groove of the sash bar and the glass plate. Although this can increase the mounting strength of the glass plate, when forming a large glass wall surface on the outer wall of the building, the sash bar will have a large finding size, which is not preferable from an aesthetic point of view. there were. That is, since the sash bar is fixed to the support member, it is necessary to absorb interlayer displacement of the glass plate during an earthquake or the like by using a bead or a sealing material. Therefore, the swallowing dimension of the glass plate with respect to the sash bar must be set to the dimension for regulating the movement of the glass plate in the out-of-plane direction, plus the dimension capable of absorbing the interlayer displacement. The dimensions were to be large. On the other hand, as constituting such a large glass wall surface, the edges of the glass plates are butt-connected to each other via a sealing material, and this connection portion is formed of a glass stiffener or a metal support member serving as a support member on the indoor side. Are connected through a sealing material. In this device, the interlayer displacement of the glass sheet is absorbed by a sealing material interposed between the edges, and the movement of the glass sheet to the indoor side is restricted by a support member, and the movement of the glass sheet to the outdoor side is connected. It is regulated by the adhesive force of a sealing material interposed between the portion and the support member. Therefore, a member such as a sash bar does not appear on the outer surface, which is preferable from an aesthetic standpoint. However, if the glass sheet moves significantly during an earthquake or the like, the sealing material between the connection portion and the support member may be cut, and there is no restriction on the movement of the glass sheet to the outdoor side, and the glass sheet is removed. There is a danger of falling or breakage. [0003] That is, in the glass plate mounting structure according to the prior art, if a sash bar is used so as to increase the mounting strength, an aesthetic problem of the building arises, and the aesthetic appearance of the building is reduced. If the sash bar is omitted for the sake of emphasis and the configuration is based solely on the adhesive performance of the sealing material, there is a problem that the mounting strength cannot be made sufficiently large. In view of the above circumstances, an object of the present invention is to provide a glass plate mounting structure that supports a glass plate with a mounting strength that is large enough to withstand the interlayer displacement by reducing the found size of a mounting member appearing outside. To be able to do it. [0004] A feature of the glass plate mounting structure according to the present invention is that a plurality of groove-shaped frames in which the edges of the glass plate are fitted in the grooves are mounted on the indoor support member. In the mounting structure of the glass sheet G in the fitted glass window attached to the glass sheet G, the inner peripheral portion of the groove and the edge of the glass sheet are fitted and fixed in a tight state, and each of the groove frames is attached to the support member. Attach the mounting hardware to be attached to the support member,
The mounting hardware and the groove-shaped frame are mounted via a flexible portion for absorbing interlayer displacement that allows sliding in all directions along the glass plate surface. [0005] Since the inner peripheral portion of the groove and the edge of the glass plate are fitted and fixed in close contact with each other, the integrity of the grooved frame and the glass plate can be improved. Even if the glass plate moves greatly during an earthquake or the like, the glass plate can be securely held by the grooved frame fitted and fixed, and the conventional glass plate is held only by the adhesive force of the sealing material. As a result, it can be held more strongly and securely. Also, the mounting hardware is attached to a support member,
Since the mounting hardware and the grooved frame are mounted via a flexible portion for absorbing interlayer displacement that allows sliding in all directions along the surface of the glass plate, interlayer displacement of the glass plate caused during an earthquake or the like occurs. Can be absorbed by the accommodating portion provided between the mounting hardware and the groove-shaped frame.
It is not necessary to provide a space for absorbing interlayer displacement of the glass plate in the groove of the groove frame. As a result, it is possible to set the swallowing dimension of the grooved frame with respect to the glass plate to the minimum size merely for restricting the movement of the glass plate in the out-of-plane direction. The size (found size) of the groove-shaped frame portion exposed to the outside of the glass plate can be made smaller and less noticeable than that provided inside. As a result, the mounting strength of the glass plate is made sufficiently large so that the glass plate can be securely and strongly mounted regardless of the interlayer displacement generated during an earthquake or the like, while the mounting member appearing on the outside. The found size of the groove-shaped frame can be made extremely small. Therefore, for example, when a large glass wall is formed on the outer wall of a building, there is an aesthetic requirement that mounting members located between the glass plates are inconspicuous, and the risk of falling or breakage of the glass plate is raised. It can be realized without fear of causing the problem. An embodiment of a glass plate mounting structure according to the present invention will be described below with reference to the drawings. FIG. 1 is a horizontal cross-sectional view of a portion where two adjacent glass plates G and G are joined to each other on a glass wall surface formed by applying the glass plate mounting structure according to the present invention. The edges of the two glass plates G are located in the first grooves 1a of the grooved frame 1, respectively. First groove 1a
Is filled with an adhesive 2 made of a special epoxy resin, a special silicon resin, or the like, and the glass plate G is fixed to the grooved frame 1 so that the two are integrated. It is configured to move. Each glass plate G and the grooved frame 1 are transported to the site in a state where they are fixed to each other in advance in a factory. The groove-shaped frame 1 has a second groove 1b formed inside the first groove 1a. In the second groove 1b, one end 3a of a U-shaped mounting member 3 made of metal such as aluminum or stainless steel is loosely fitted. The other end 3b of the mounting hardware 3 is fixed to an aluminum or steel mullion 4, which is a support member on the indoor side, as described later.
In the second groove 1b of the grooved frame 1, one end 3a of the mounting hardware 3 can be relatively moved in all directions along the surface of the glass plate G. That is, the interlayer displacement generated during an earthquake or the like is absorbed by the relative movement between the mounting hardware 3 and the grooved frame 1. Therefore, the first of the grooved frame 1 of the glass plate G
Can be made small enough to simply restrict the movement of the glass plate G in the out-of-plane direction without adding a dimension for absorbing interlayer displacement. In addition, since the glass plate G and the grooved frame 1 can be fixed to each other, and the mounting strength can be borne by this, the structure is different from a structure in which the glass plate G and the grooved frame 1 are merely overlapped to obtain the strength. Thus, the swallowing dimension can be further reduced. As a result, it is possible to make the grooved frame 1 appearing on the outside of the glass wall surface small and inconspicuous, while having sufficient mounting strength. Next, referring to FIG. 1 and FIG.
The structure for attaching to the mullion 4 will be described. The mounting hardware 3 is a thread having a length substantially equal to the length of the glass plate G in the vertical direction.
A screw hole 3x is formed at an appropriate position in the longitudinal direction. On the other hand, on the flange 4A of the mullion 4, a stupid hole 4x is formed at a position corresponding to the screw hole 3x of the mounting hardware 3, and a rubber washer 5 and a washer 6 are provided on the edge of the stupid hole 4x via a rubber washer 5 and a washer 6. The first bolt 7 with which the contact 7a comes in contact with the mounting hardware 3
Screw holes 3x. The flange 4A of the mullion 4 has a screw hole 4 adjacent to the lower side of the stupid hole 4x.
The tip of the second bolt 8 screwed into the screw hole 4y is brought into contact with the inner end 3b of the mounting hardware 3. One of the two bolts 7 and 8 serves to pull the glass plate G toward the mullion 4 and the other to push the glass plate G out of the mullion 4. That is, by rotating the first bolt 7 in the forward direction, the glass plate G is drawn toward the mullion 4 via the mounting hardware 3, and the movement of the glass plate G outward from that state is restricted. . Further, by rotating the second bolt 8 in the forward direction, the glass plate G is pushed out of the mullion 4 via the mounting hardware 3, and the glass plate G is prevented from moving inward from that state. That is, the pair of bolts 7,
8, the glass plate G and the mullion 4 can be fixed by arbitrarily changing the relative position in the thickness direction of the glass plate G. Then, a bolt pair S which is an example of a position adjusting mechanism including the above-described pair of bolts 7 and 8 is used.
Are provided in each of two places in the vertical direction. In other words, when a plurality of glass plates G are juxtaposed to form a large glass wall surface, the relative position between the glass plate G and the mullion 4 is finely adjusted at two locations above and below the left and right sides of each glass plate G. In addition, the glass plate G can be attached and mounted in a state of high smoothness of the entire glass wall surface required when a mirror glass is used as the glass plate G. As shown in FIG. 1, a sealing material 10 is filled after a backup material 9 is fitted between the groove-shaped frames 1 adjacent to each other on the left and right sides so that sufficient waterproofness can be obtained as an outer wall. is there. In FIG. 1, reference numeral 11 denotes a decorative plate fixed to the mullion 4, and reference numeral 12 denotes a gasket. FIG. 2 is a vertical sectional view showing a portion where the upper and lower glass plates G are joined. This portion has a structure in which a sash bar is combined as in the conventional case. That is, the sash bar 14 serving as the blank is fixed to the bracket 13 fixed to the mullion 4 by bolts.
The lower end of the upper glass plate G and the upper end of the lower glass plate G are inserted into the upper and lower grooves formed by the upper and lower sash bars 15 and 16 and the blind sash bar 14. The edges are fitted respectively, and fixed by a gasket 17 and a sealing material 18 made of silicone resin. In addition, 19 in the figure is a bracket for fixing the mullion 4 to a C-shaped steel 20 erected horizontally, and 21 is a fireproof plate attached to the C-shaped steel 20 via a bracket 22. FIG. 4 shows two glass plates G adjacent to each other on the left and right.
FIG. 9 is a horizontal cross-sectional view showing another embodiment of the portion where the parts are joined.
In this embodiment, a stainless steel plate 23 is slidably fitted in a vertical direction in a guide frame A connected to an inner end of the mounting hardware 3. 4 and 5, a screw hole 23x is formed in the stainless plate 23, and a first bolt 24 screwed into the screw hole 23x is formed in the flange 4A of the mullion 4. Through the fool hole 4x, and a rubber washer 25 is attached to the edge of the fool hole 4x.
The head 24a is locked via the and the washer 26. The flange 4A of the mullion 4 has a stupid hole 4
Two screw holes 4y and 4z are formed adjacent to the upper side and the lower side of x, respectively, and the tips of the second and third bolts 27 and 28 respectively screwed into the screw holes 4y and 4z are made of stainless steel. Is made to abut against a plate piece 23 made of aluminum. That is, the three bolts 24, 27, 28 described above allow the glass plate G
The structure is such that the relative positions of the glass plate G and the mullion 4 in the thickness direction can be arbitrarily changed and fixed. A position adjusting mechanism S composed of the three bolts 24, 27, and 28 and the stainless steel plate 23 is provided at two locations in the vertical direction, as in the case of the above-described embodiment. The glass plate G can be attached and mounted in a state of high smoothness of the entire glass wall surface. In the embodiment shown in FIGS. 1 and 4, the relative movement between the grooved frame 1 and the mounting hardware 3 causes the glass plate G to move.
Sliding in the direction along the surface is allowed, and the combination is referred to as a flexible portion F. The specific configuration of the flexible portion F can be changed as appropriate. For example, in the configuration shown in FIG. 1, the mounting hardware 3 may not be a threaded material, but may be a piece provided at several places in accordance with the dimensions of the glass plate G. . In this case, as shown in FIG. 4, the position adjusting mechanism S is provided with two pushing bolts for one pulling bolt of the glass plate G, or conversely, one pushing bolt is used. By providing two bolts for attracting
It is preferable to prevent the fitting 3 from twisting. Further, when the mounting hardware 3 is a through object, it is preferable to adopt the above-described push-pull bolt configuration. further,
In practicing the present invention, the accommodation portion F does not necessarily have to have the position adjustment mechanism S. Also, the mounting hardware 3 in the case of a piece and a plate 23 made of stainless steel or the like.
The number and arrangement in the vertical direction can be appropriately changed according to the size and thickness of one glass plate G and the required mounting strength. The structure of the portion where two vertically adjacent glass plates G are joined can be appropriately changed instead of the structure shown in FIG. For example, the structure shown in FIG. 6 is obtained by applying the structure shown in FIG.
That is, the groove-shaped frame 1 is attached to the edge of the glass plate G via the adhesive 2.
The first groove 1a is fixed. Second groove 1 of grooved frame 1
One end 3a of the mounting hardware 3 made of aluminum or stainless steel is loosely fitted in b, and allows sliding in all directions along the plate surface of the glass plate G. The other end 3b of the metal fitting 3 is fixed to the mullion 4 on the indoor side by a bolt pair S provided at an appropriate position in the horizontal direction so that the mounting position in the thickness direction of the glass plate G can be changed. A bolt 30 screwed to a bracket 29 fixed to the mullion 4 is in contact with the lower surface of the grooved frame 1 fixed to the upper glass plate G, so as to support the weight of the glass plate G.
