Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to the glass support structure in a curtain wall structure that is supported by a self-weight receiving member in which the self-weight of the glass is fixed in a vertical direction without having an eyelessness.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a structure in which a curtain wall structure that forms a wall surface of a building or the like does not have an eyelessness in order to produce a feeling of opening, and glass is supported only by a vertical.
[0003]
Specifically, as shown in FIG. 11, this curtain wall structure uses a vertical 50 having glass fitting grooves M, M on both the left and right sides, and the vertical 50 is formed in a frame or the like at predetermined intervals in the horizontal direction. In addition to fixing, the glass receiving members 51 and 51 are fixed at predetermined positions in the longitudinal direction of the vertical 50 and the glass receiving members 51 and 51 support the glass by supporting the end portions of the glass G and G. Is. Seals are filled in the joints between the glasses adjacent in the vertical direction so as to ensure airtightness.
[0004]
In the case of the curtain wall structure, it is natural that the joint width between the adjacent glasses in the upper and lower sides should be as small as possible. However, if each glass rotates in the same direction due to interlayer displacement during an earthquake, Since there is a possibility that the upper side corner portion may come into contact with the glass receiving member 51 and be damaged, the joint width has to be increased to some extent. Further, since the interlayer displacement is proportionally increased as the glass width dimension is increased, there is a problem that the joint seal impairs the feeling of opening and the construction of the joint seal becomes difficult.
[0005]
In order to cope with such a problem, the following Patent Document 1 proposes a glass support structure in which the glass receiving member 51 is movable from the mounting position to the lower side while being movable from the lower side. In the case of this glass support structure, interlayer displacement is caused from the state of FIG. 12A, and as shown in FIG. 12B, each glass rotates in the same direction, and the upper end corner of the glass is a glass receiving member. Even if it collides with 51, breakage of the glass G is prevented by the glass receiving member 51 moving upward.
[0006]

[Problems to be solved by the invention]
However, even in the case of the glass support structure described above, as shown in FIG. 12, since the glass receiving member 51 exists between the upper and lower adjacent glasses G and the joints of the G, at least the glass receiving member. The glass joint width could not be made smaller than the thickness dimension of the member 51, and there was naturally a limit to reducing the joint joint width.
[0008]
Furthermore, since the glass receiving member 51 protruding sideways is not exposed to the outside and needs to be hidden in the vertical, there is a problem that the vertical width of the vertical can not be reduced.
[0009]
Therefore, the main problem of the present invention is to prevent the glass from being damaged at the time of interlayer displacement in the curtain wall structure that is supported by the glass receiving member that has the weight of the glass fixed in a vertical direction without having an eyelessness. It is an object of the present invention to provide a glass support structure in which the joint width between adjacent glasses in the vertical direction can be made vertical, the minimum dimension considering the glass temperature movement can be made, and the vertical width of the stand can be reduced.
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, as the present invention according to claim 1, in a curtain wall structure that has no weight and is supported through a self-weight receiving member in which the glass weight is fixed in a vertical direction,
Fixing the self-weight receiving member at a position where the upper end of the glass does not collide when the interlayer is displaced, and fixing a support metal fitting having a hook on each of the lower end side corners of the glass,
Each glass is installed so that the latch hook of the support fixture fixed to the glass is hooked to the weight receiving member fixed in a vertical manner, and there is no support fixture in the gap between adjacent glasses A glass support structure in a curtain wall structure characterized by having a structure is provided.
[0011]
As the present invention according to claim 2, in a curtain wall structure that is supported through a self-weight receiving member that is fixed in a vertical direction without having a weightlessness,
Fixing brackets having latching hooks extending to the indoor side at the lower corners of the glass are fixed, and the latching hooks are latched at positions closer to the indoor side than the glass surface on the vertical side. Fix the weight receiving member,

At times the glass upper end does not collide, for example, the weight receiving member is fixed at a position on the indoor side of the glass surface, and the support fittings having the hooks are fixed to the lower end side corners of the glass, respectively. Each glass was installed so that the latch hook of the support fitting was hooked to the weight receiving member fixed in a vertical manner, and the support fixture was not present in the glass gap between the upper and lower sides. Therefore, since there is no support metal fitting in the glass gap, the joint width between adjacent glasses in the vertical direction can be set to be the minimum size considering the glass temperature movement, and the glass has a lower end on one side when the interlayer is displaced. Even if it rotates around the center and the upper end of the other side is lifted, the glass is prevented from being broken because there is no support fitting. Moreover, since the said glass receiving member is arrange | positioned indoors (back side) rather than the glass surface, it becomes possible to also make a vertical find width dimension small.
[0013]
As the present invention according to claim 3, the support metal fitting comprises a metal fitting main body fixed to glass and the hook hook integrally extending from the metal fitting main body, and the metal fitting main body has a substantially U-shaped cross section. And a bottom surface portion. The glass edge is fitted into a space formed by the substantially U-shaped cross section and the bottom surface portion, and is fixed integrally to the glass. 2. A glass support structure in a curtain wall structure according to any one of 2 is provided.
[0014]
As the present invention according to claim 4, both side edges of the glass are fitted into glass fitting grooves formed along the vertical direction of the vertical, respectively, on the outdoor side and indoor side of the glass side edges, respectively. The glass support structure in the curtain wall structure according to any one of claims 1 to 3, wherein the glass support structure is supported by the inserted elastic packing, and a seal is applied to the outside thereof to ensure watertightness and airtightness. Provided.

It is a member. The pressing edges 3 and 4 are supported by the pressing edge locking pieces 2e and 2e, and glass fitting grooves M and M are formed together with the glass holding pieces 2b and 2c.
[0018]
In the spaces formed by the glass holding pieces 2b and 2c and the vertical ribs 2d, the self-weight receiving members 5 and 5 are fixed to the vertical 2 respectively. As shown in FIG. 6, the self-weight receiving member 5 includes an upper locking piece 5 a for fixing to the vertical 2 and a self-weight receiving piece on which a hook 8 </ b> B of a glass support fitting 8 to be described later is hooked. A cushioning material 7 made of resin, rubber or the like is installed on the self-weight receiving piece 5b, which is a member comprising 5b and a hanging piece 5c having a bolt through hole 5d for fixing to the vertical 2.
[0019]
As shown in FIG. 4, the self-weight receiving member 5 is attached in a state where the upper locking piece 5a is locked to the opening 2f formed in the vertical 2, and is inserted through the bolt through hole 5d. The bolt 6 is firmly fixed to the vertical 2.
[0020]
On the other hand, support metal fittings 8 and 8 are fixed to both lower corners of the glass G so that the glass G is supported by the weight receiving members 5 and 5, respectively. As shown in FIG. 6, the support metal fitting 8 is constituted by a metal fitting body 8 </ b> A fixed to the glass G and a latching hook portion 8 </ b> B extending integrally from the metal fitting body 8 </ b> A. The metal fitting body 8A has a shape having a substantially U-shaped section formed by front and back walls 8a, 8b and a side wall 8c in plan view, and a bottom surface portion 8d. The glass edge is fitted into the space formed by 8d so as to be integrally fixed to the glass G. Although the glass G can be directly fitted into the glass fitting portion, as shown in FIG. 7, a protective material 9 having a substantially U-shaped cross section made of a rubber material or the like is interposed therebetween. Is desirable. The latch hook 8B is provided to extend indoors while being flush with the side wall 8c, and a stepped notch 8e is formed on the lower side.
[0021]
