Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is designed to support two glass pieces in abutment with a glass support device for a corner opening of a curtain wall, for example, a corner opening of a curtain wall. Glass support device.

[Conventional technology]

Conventionally, the position of the opening has been kept as far as possible from the corner of the building because of strength considerations. Therefore, the corners tended to be dark, and the image was not very good. However, recent technological advances have made it possible to obtain strong guarantees, and the number of cases where a corner opening is provided has increased, so the lighting and perspective of the corner have improved, and the image of the corner has changed.

The projecting corner opening has a strong tendency to be adopted in a curtain wall in which the position of the opening can be changed relatively easily. In the construction, upper and lower horizontal frames connected in an L shape are attached between adjacent left and right vertical frames to form a projecting corner opening on each floor, and two glass pieces are abutted and fitted into the opening. In principle, the glass support is no different from the general window construction. Therefore, in the lower horizontal frame, a plurality of setting blocks are evenly arranged in the glass fitting groove to support the glass load evenly, while in the upper horizontal frame, the ridge is applied from the outside to support the glass upper edge. I have to.

[Problems to be solved by the invention]

The projected corner opening has a window structure that opens continuously in two directions, giving a good view and excellent lighting. Therefore, although the open feeling is significantly better than other window configurations, one of them may suffer a structural disadvantage.

In the general window structure, the horizontal frame has a structure that supports both ends,
The deflection at the center is the largest, but the projecting corner opening has a cantilever structure, and the deflection at the connecting portions of the upper and lower horizontal frames is the largest. Comparing these deflections under the same frame and load conditions, the latter is overwhelmingly larger and may adversely affect the appearance.

On the other hand, Japanese Utility Model Laid-Open No. 60-141381 discloses that an L-shaped setting block is provided on the upper horizontal frame.

However, this is such that the end surface of the first glass is brought into contact with one piece of the setting block and the end surface of the second glass is brought into contact with the other piece, and the outdoor surfaces of the first glass and the second glass are
Since there is no means for holding it, it is not possible to hold it stably on the upper cross member.

Therefore, an object of the present invention is to reliably support the load and the rotation moment of the glass, and to firmly hold the glass particularly against the tilting force of the glass to the outside.

[Means for solving problems]

In order to achieve the above object, the present invention arranges adjacent left and right vertical frames vertically, and horizontally arranges L-shaped horizontal frames vertically to form a projecting corner opening. In the glass support device of the projected corner opening part in which the first glass and the second glass are fitted in the glass fitting groove formed in, in the vicinity of the left and right vertical frames in the glass fitting groove of the lower horizontal frame,
A lower setting block that supports a glass load is attached, and an upper setting block that supports the glass butt portion is attached to the glass butt portion in the glass fitting groove of the upper horizontal frame. The upper setting block is L-shaped as a planar shape. In one piece of the body piece of, having a width that is thicker than the thickness of the first glass, spaced apart from the other piece of the body piece, and having a piece that projects orthogonally inward, A state in which the butt end of the upper end of the first glass is inserted between the upper end of the first glass and the butt end of the upper end of the second glass abuts the inner end of the one piece. The butt end of the first glass is the other piece,
The second glass is held by a space piece and a piece therebetween, and the second glass is held by the space piece and the space piece.

[Action]

In the present invention, most of the glass load is set so that the vertical frame of the lower horizontal frame acts on the burr through the lower setting block.

Assuming that the glass load remains the same in the present invention and in the past, the distributed load acts on the entire lower frame in the past, and the distributed load acts only on the vertical frame in the present invention. Compared with, the present invention is much smaller. Therefore, the influence on the appearance is small.

On the other hand, the stability of the glass is poor at the connecting part, and a rotating moment from the outer part is generated at the center of the glass, but that moment is offset by the upper setting block attached to the butting part of the glass fitting groove. Has been Therefore, tension commensurate with the rotational moment is applied to the upper horizontal frame via the upper setting block. This tension is effective not only for supporting the glass but also for reducing the bending of the connecting portion.

Further, in the present invention, particularly, the upper setting block is provided with a first piece on an L-shaped body piece as a plane shape.
With a width that is thicker than the thickness of the glass, with a spacing distance from the other piece of the main body piece, and with a piece that protrudes inward orthogonally,
An abutting gutter end of the upper end of the first glass is inserted between the one piece and the interstitial piece, and an abutting gutter end of the upper end of the second glass is attached to the indoor side of the other piece. The upper end of the first glass is held by the other piece, the interpiece and one piece between them, and the second glass is held by the one piece and the interpiece. Therefore, the first glass and the second glass are firmly held against falling to the outside of the room.

〔Example〕

 Hereinafter, embodiments will be described with reference to the drawings.

In the embodiment, as shown in FIG. 1, a curtain wall 1 serving as an outer wall of a building is provided with a projected corner opening 2, and two first glass G ₁ and a second glass G ₂ fitted into the opening 2 are fitted. The detailed construction is shown in FIG. 2 and subsequent figures.

First, the outline will be described with reference to FIG. 1 to FIG. 3. On the adjoining wall surfaces of the curtain wall 1, the vertical frames 3 and 3 are removed by removing the corners of the wall surface and the height of the building frame. The upper and lower horizontal frames 4 and 5 which are arranged in the direction and which are connected to each other in a plane L shape by forming wall surfaces between the vertical frames 3 and 3 are attached in parallel at predetermined intervals by screws or bolts.

The projected corner opening 2 is formed on a curved surface connecting the vertical frames 3 and 3 and the upper and lower horizontal frames 4 and 5, as shown in FIG. There is no vertical frame that supports ₁ and G ₂ at the same time. Therefore, the glass fitting grooves 3a, 4a, 5 of each of the frames 3, 4, 5 are placed with the two pieces of glass butted against each other.
Although it is fitted into and supported by a, in the conventional example, the lower horizontal frame 5
In Gawa, a plurality of setting blocks are usually arranged evenly in the glass fitting groove 5a so as to receive the glass load evenly. Evenly distributed load acts on the lower horizontal frame 5, but since the support structure is also a cantilever structure, the deflection of the connection portion A is relatively large compared to other window configurations. If this deflection is compared with the maximum deflection of a horizontal frame that is supported or fixed at both ends, it is 10 for the former.
Double, and 50 times for the latter. As a result, the projected corner opening 2 has an effect that the lighting and the view of the corner are good, but on the other hand, the bending of the connection portion is large, and there is an element that may affect the appearance shape.

The present invention does not completely eliminate the above-mentioned deflection, but is designed to support _two glasses G ₁ and G _{2 by} making them so small as not to affect the external shape.

Therefore, as shown in FIG. 1, the glass fitting groove 5 of the lower horizontal frame 5 is
A vertical frame 3 supports a glass load on the lower side of a, and a lower setting block 6 is arranged on the a, while a glass fitting groove 4a of the upper horizontal frame 4 supports the glass G ₁ and G ₂ butting parts. The upper setting block 7 is attached.

The lower setting block 6 in which the vertical frame 3 is arranged in the loop
Since it can support a glass load, it is desired to be made of a material that withstands the load and is as strong as possible in deformation resistance, and may be formed using a metal such as aluminum in consideration of corrosion resistance. Moreover, the shorter the lower setting block 6 is, the greater the effect is. However, the glass G ₁ , G ₂
Since it is preferable that the glass fitting groove 5 formed in the lower horizontal frame 5 is used as a contact point, it is preferable that the glass fitting groove 5 is as long as possible.
About half the length of a may be taken as the length of the lower setting block 6. Further, when the maximum deflection needs to be accommodated at least in the degree of supporting both ends, it may be reduced to about 1/4 or less at the expense of the stability of the glasses G ₁ and G ₂ . Assuming that the maximum deflection when a uniformly distributed load is applied to the entire lower horizontal frame 5 is 1, when the length of the lower setting block 6 is half the length of the glass fitting groove 5a, the maximum Deflection is reduced to about 3/10 and 1/4 to 8/100.
Therefore, it can be seen that even 1/2 is sufficient.

On the other hand, in the upper horizontal frame 4, normally, as shown in FIG. 3, a ridge 8 is applied from the outside, and a bead 9 or a seal 10 is filled in a gap between the glass G ₁ and G ₂ to support the glass upper edge. However, if the length of the lower setting block 6 is short, a rotational moment is generated at the centers of the glass G ₁ and G ₂ , and the other gives a local load to the ridge and the seal. The ridge 8 is generally screwed to the upper horizontal frame 4, but the seal 10 is flexible and weak against deformation. Therefore, one end of the lower setting block 6 where the glass load is at the center of the glass fitting groove 5a The effect obtained by the present invention diminishes. The same thing can happen when the screw comes off or cannot bear the load and the ridge 8 is deformed or damaged.

Therefore, the present invention is directed to the glass fitting groove 4 formed in the upper horizontal frame 4.
The upper setting block 7 shown in FIGS. 4 and 5 is attached to the abutment block of a so that the _two glasses ₁ and G ₂ are simultaneously supported and the glasses G ₁ and G ₂ are supported.
The upper lateral frame 4 cancels the rotational moment generated at the center of the frame.

The upper setting block 7 prevents falling to the outside of the room as indicated by the arrow in FIG. 2 and, at the same time, the illustrated glass G ₁ , G ₂
Since the sealing material 11 is packed in order to seal the butted portion, the sealing width is ensured so that the sealing material 11 is not overloaded, and the first glass G ₁ and the second glass G ₁
In order to securely hold the abutting end of the upper end of the glass G ₂ , as shown in FIGS. 4 and 5, the thickness of the first glass G ₁ is attached to one piece 7c of the L-shaped body piece as a planar shape. A piece 7a having a thicker width and spaced apart from the other piece 7b of the main body piece and projecting inward at right angles is formed.

In the upper setting block 7 having such a structure,
The butt end of the upper end of the first glass G ₁ is inserted between the piece 7c and the piece 7a, and the piece 7c
Of the upper end of the second glass G ₂ is arranged so that the outer surface of the butt end of the second glass G ₂ is in contact with the spacer piece 7 a, and as a result, the upper end of the first glass G ₁ is butt end. Is held by the other piece 7b, the space piece 7a and the space piece 7c between them, and the second glass G ₂ is held by the space piece 7c and the space piece 7a. Thus, the first and second glass glasses G ₁ and G ₂ are stably held.

[Effect of device]

As described above, according to the present invention, the bending of the connecting portion can be reduced to the extent that it does not affect the external shape, and of course, the first and second glass glasses G ₁ and G ₂
Can be stably held.
