Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a structure for attaching a glass plate in a fitted glass window.

[Conventional technology]

Conventionally known mounting structures for glass plates include the following.

First, there is one in which a sash bar is fixed to a support member on the indoor side, a glass plate is fitted into a groove in the sash bar, and a bead or sealant is interposed between the groove in 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 a building, the dimensions of the sash bar become large, which is not aesthetically pleasing. Ta.

In other words, 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 using beads or a sealant. Therefore, the size of the glass plate to be swallowed by the suction bar must be determined by adding a dimension that can absorb the interlayer displacement to a size that restricts the movement of the glass plate in the out-of-plane direction. It was larger in size.

On the other hand, in order to construct such a large glass wall surface, the edges of the glass plates are butted and connected to each other through a sealant, and this connection part is connected to a glass stiffener that is a support member on the indoor side or a metal Some mullions are connected via sealant. This device absorbs the interlayer displacement of the glass plate by a sealing material interposed between the edges, and also controls the movement of the glass plate toward the indoor side by a supporting member, and moves the glass plate toward the outdoor side. The movement of is regulated by the adhesive force of the sealing material interposed between the connecting portion and the supporting member.

Therefore, members such as the sash bar do not appear on the outside, which is aesthetically pleasing. however,
If the glass plate moves significantly during an earthquake,
The sealing material between the connection part and the support member may be cut, and the movement of the glass plate to the outside will no longer be restricted, creating a risk of the glass plate falling or being damaged. Ta.

[Problem that the invention seeks to solve]

In other words, in the conventional structure for attaching glass plates, if a suction bar is used to increase the installation strength, it will cause problems with the aesthetics of the building. If the configuration relied solely on performance, there would be a problem in that the mounting strength could not be made sufficiently large.

In view of the above-mentioned circumstances, an object of the present invention is to provide a glass plate mounting structure in which the dimensions of the mounting members appearing on the outside are reduced, and the glass plate is supported with sufficient mounting strength to withstand interlayer displacement. The goal is to make it possible.

[Means for solving problems]

The characteristic configuration of the glass plate mounting structure according to the present invention is that the edge of the glass plate is fixed in the groove of the grooved frame, and the grooved frame is attached to the support member on the indoor side in all directions along the glass plate surface. The reason is that a flexible part for absorbing interlayer displacement is installed to allow sliding between the layers.

[Effect]

In other words, since the flexible part absorbs the interlayer displacement of the glass plate that occurs during an earthquake, there is no need to add a dimension to absorb the interlayer displacement as the swallowing dimension of the glass plate into the grooved frame, and it is not necessary to add a dimension to absorb the interlayer displacement, but simply It is sufficient that dimensions for restricting outward movement are ensured.

Furthermore, since the structure is not designed to absorb interlayer displacement between the glass plate and the grooved frame, both can be fixed, and this fixing structure itself is responsible for regulating the movement of the glass plate in the out-of-plane direction. According to
The swallowing dimension of the glass plate into the groove-shaped frame can be further reduced compared to the case where strength is obtained simply by overlapping the glass plate and the edge of the groove-shaped frame.

〔Effect of the invention〕

As a result, the mounting strength of the glass plate is made sufficiently large so that the glass plate can be mounted securely and strongly regardless of interlayer displacement that occurs during earthquakes, etc., and the dimensions of the groove-shaped frame as a mounting member that appears on the outside are made large enough. can be made extremely small.
Therefore, for example, when configuring a large glass wall on the exterior wall of a building, aesthetic requirements such as making the mounting members located between the glass panels inconspicuous have to be avoided when the glass panels fall or break. It is now possible to realize this without the risk of incurring any danger.

〔Example〕

Embodiments of the glass plate mounting structure according to the present invention will be described below based on the drawings.

FIG. 1 is a horizontal cross-sectional view of a portion of a glass wall constructed by applying the glass plate mounting structure according to the present invention, where two adjacent glass plates G, G meet.

The edges of the two glass plates G are located within the first grooves 1a of the groove-shaped frame 1, respectively. An adhesive 2 made of a special epoxy resin or a special silicone resin is applied between the inner periphery of the first groove 1a and the glass plate G.
The glass plate G is fixed to the groove-shaped frame 1 so that the two move together.
Each glass plate G and the groove-shaped frame 1 are transported to the site in a state in which they are fixed to each other in advance at a factory.

The groove-shaped frame 1 has a second groove 1 inside the first groove 1a.
b is formed. One end 3a of a mounting hardware 3 made of a metal such as aluminum or stainless steel and having a U-shape in cross section is loosely fitted into the second groove 1b. As will be described later, 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, and extends inside the second groove 1b of the groove-shaped frame 1. , one end 3a of the mounting hardware 3 is configured to be relatively movable in all directions along the surface of the glass plate G.

In other words, the interstory displacement that occurs during an earthquake or the like is absorbed by the relative movement between the mounting hardware 3 and the groove-shaped frame 1. Therefore, the swallowing dimension of the groove-like frame 1 of the glass plate G with respect to the first groove 1a can be set simply to restrict the movement of the glass plate G in the out-of-plane direction without adding a dimension for absorbing interlayer displacement. You can make it as small as you need. Also,
The glass plate G and the grooved frame 1 can be fixed,
As a result, the mounting strength can be provided, and the swallowing dimension can be further reduced compared to a structure in which strength is simply obtained by overlapping the glass plate G and the groove-shaped frame 1.

As a result, the groove-shaped frame 1 appearing on the outside of the glass wall surface can be made smaller and less noticeable while maintaining sufficient mounting strength.

Next, using Figures 1 and 3, install the mounting hardware 3.
The mounting structure to the mullion 4 will be explained. The mounting hardware 3 is a through piece with approximately the same length as the vertical length of the glass plate G, and screw holes 3x are inserted at appropriate locations in the longitudinal direction.
has been formed. On the other hand, flange 4 of mullion 4
In A, a blank hole 4x is formed at a location corresponding to the screw hole 3x of the mounting hardware 3, and a first hole 7a is in contact with the edge of the blank hole 4x via a rubber washer 5 and a washer 6. A bolt 7 is screwed into the screw hole 3x of the mounting hardware 3. Also, Marion 4
A screw hole 4y is formed in the flange 4A adjacent to the upper side of the blank hole 4x. It is placed in contact with the

One of the aforementioned two bolts 7 and 8 serves to attract the glass plate G toward the mullion 4, and the other serves to push the glass plate G away from the mullion 4. That is,
By rotating the first bolt 7 in the forward direction, the glass plate G is attached to the mullion 4 via the mounting hardware 3.
From this state, the glass plate G is prevented from moving outward. Further, by rotating the second bolt 8 in the forward direction, the glass plate G is pushed out from the mullion 4 via the mounting hardware 3, and from this state, the glass plate G is prevented from moving inward. be done. In other words, by the cooperation of the pair of bolts 7 and 8, the relative positions of the glass plate G and the mullion 4 in the thickness direction of the glass plate G can be arbitrarily changed and fixed.

Two pairs of bolts S, which are an example of a position adjustment mechanism consisting of the above-mentioned pair of bolts 7 and 8, are provided at two locations in the vertical direction. In other words, when configuring a large glass wall surface by installing multiple glass plates G, fine adjustment of the relative position between the glass plate G and the mullion 4 at two locations on the left and right sides of each glass plate G is possible. Therefore, the glass plate G can be installed in a state where the glass wall surface as a whole has high smoothness, which is required when mirror glass is used as the glass plate G.

In addition, as shown in FIG. 1, a sealing material 10 is filled between the groove-shaped frames 1 adjacent to each other on the left and right after the back-up material 9 is fitted in order to obtain sufficient water-stopping properties as an outer wall. There is. In addition,
In FIG. 1, 11 is a decorative plate fixed to the mullion 4, and 12 is a gasket.

FIG. 2 is a vertical sectional view showing a portion where the upper and lower glass plates G meet. This part has a structure that combines a suction bar in the same way as in the past. That is, the suction bar 14, which is a blank material, is bolted to the bracket 13 fixed to the mullion 4, and the upper and lower suction bars 15, 16, which are engaged with the blank suction bar 14, are connected to the bracket 13 fixed to the mullion 4. The lower edge of the upper glass plate G and the upper edge of the lower glass plate G are respectively fitted into the upper and lower grooves formed by the glass plate G, and are fixed with a gasket 17 and a silicone resin sealant 18. . In the figure, 19 is a bracket for fixing the mullion 4 to the C-shaped steel 20 installed horizontally, and 21 is a fireproof plate attached to the C-shaped steel 20 via the bracket 22.

FIG. 4 is a horizontal sectional view showing another embodiment of the joining portion of two glass plates G adjacent to each other on the left and right sides. In this device, a stainless steel plate piece 23 is fitted into a guide frame A connected to the inner end of the mounting hardware 3 so as to be slidable in the vertical direction. As shown in FIGS. 4 and 5, a screw hole 23x is formed in the stainless steel plate piece 23, and the first bolt 2 is screwed into the screw hole 23x.
4 passes through a hole 4x formed in the flange 4A of the mullion 4, and the head 24 is attached to the edge of the hole 4x via a rubber washer 25 and a washer 26.
a is locked. Furthermore, two screw holes 4y and 4z are formed in the flange 4A of the mullion 4 adjacent to the upper and lower sides of the hole 4x, and second and second screw holes 4y and 4z are formed to be screwed into the screw holes 4y and 4z, respectively. The tips of the bolts 27 and 28 of No. 3 are brought into contact with a plate piece 23 made of stainless steel, respectively.

In other words, the three bolts 24, 27, 2 mentioned above
8, the relative position of the glass plate G and the mullion 4 in the thickness direction of the glass plate G can be arbitrarily changed and fixed. Then, position adjustment mechanisms S made up of these three bolts 24, 27, 28 and a stainless steel plate piece 23 are provided at two locations in the vertical direction, and as in the case of the previously described embodiment, The glass plate G can be installed while the entire glass wall surface is highly smooth.

In the case shown in FIGS. 1 and 4, sliding in the direction along the surface of the glass plate G is allowed by relative movement between the grooved frame 1 and the mounting hardware 3, and the combination thereof is called the flexible part F.

The specific configuration of the flexible part F can be changed as appropriate,
For example, in the one shown in FIG. 1, the mounting hardware 3 may not be a through piece, but may be a piece piece that is provided at several locations depending on the dimensions of the glass plate G. In this case, the position adjustment mechanism S may be configured such that two pushing bolts are provided for one drawing bolt of the glass plate G, as shown in FIG. 4, or, conversely, one pushing bolt is provided. It is preferable to provide two pulling bolts to prevent twisting of the mounting hardware 3. Further, in the case where the mounting hardware 3 is a through-piece, it is also preferable to use a push-pull bolt configuration as described above. Furthermore, in carrying out the present invention, the flexible part F does not necessarily have to have the position adjustment mechanism S.

In addition, the number and arrangement of the mounting hardware 3 in the vertical direction and the plate pieces 23 made of stainless steel or the like in the case of a piece type are determined based on the size and thickness of one glass plate G and the required installation. It can be changed as appropriate depending on the strength.

The structure of the connecting portion between two vertically adjacent glass plates G can also be changed as appropriate instead of the one shown in FIG.

For example, the structure shown in FIG. 6 is a structure in which the structure shown in FIG. 1 is applied almost as is to the upper and lower connecting parts. That is, the first groove 1a of the groove-shaped frame 1 is fixed to the edge of the glass plate G via the adhesive 2. One end 3a of a mounting hardware 3 made of aluminum or stainless steel is loosely fitted into the second groove 1b of the groove-shaped frame 1, allowing sliding in all directions along the surface of the glass plate G. I'm starting to do that. Then, the other end 3b of this mounting hardware 3 is fixed to the mullion 4 on the indoor side by means of a pair of bolts S provided at appropriate locations in the horizontal direction, so that the mounting position in the thickness direction of the glass plate G can be changed. be. In addition,
A bolt 30 screwed into 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, and is configured to support the weight of the glass plate G. be.

Instead of this structure, the structure shown in FIG. 4 described above may be applied to the upper and lower connecting parts.

In addition, when configuring the glass wall surface of a building, any of the left and right joint portions described above and any of the upper and lower joint portions may be combined as appropriate.

The glass plate G to which the present invention is applied is not limited to a plurality of glass plates forming a large glass wall surface as explained in the previous embodiment, but may also be a single glass plate G forming a single closed window. .
