Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a curtain wall, and more particularly to a structure in which a vertical frame is fixed to the left and right of a wall body, and a narrow panel is attached between adjacent vertical frames.
[0002]
[Prior art]
As shown in FIG. 9 (A), the curtain wall can be slightly moved up and down and left and right on a bracket 62 in which a corner portion of a rectangular wall body 60 is attached to a vertical body (not shown). The walls 60 are supported by being joined by a soft structure, and the walls 60 are sealed by an elastic sealing material 64 to allow relative movement between the walls 60, thereby allowing the upper and lower sides to be adjacent in the event of an earthquake. Corresponding to relative lateral movement (interlayer movement) on the floor.
[0003]
[Problems to be solved by the invention]
In the curtain wall having the conventional structure described above, as shown in FIG. 9 (B), for example, a vertically long panel 66 made of, for example, glass is interposed between rectangular wall bodies 60 made of, for example, stone tone, and thus different appearances are provided. In order to obtain the structure, since the wall body 66 is interposed between the side portions of the wall body 60 having a large relative displacement, the wall body 66 is mounted so that the displacement of the wall body 66 is within the allowable range of elastic deformation of the sealing material 64. Therefore, the width t1 of the sealing material 64 around the wall body 66 is very large relative to the width t2 of the wall body 66, which is uneconomical.
[0004]
In view of the above problems, an object of the present invention is to provide a curtain wall that can absorb interlayer displacement with a simple structure when a curtain wall is configured by interposing a narrow and long panel between walls. .
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention fixes in advance a vertical frame on the side surface of the wall body so as to be integrated with the wall body, attaches an insignia between the vertical frames of adjacent wall bodies, and extends the vertical frame in the horizontal direction. A panel with a shape that is long in the direction is placed on the above-mentioned surface so as to be laterally movable through a setting block, and a narrow-width panel is placed between both side surfaces of the narrow-width panel and the vertical frames of the left and right wall bodies. A holding member for holding the vertical frame so as to be movable up and down is interposed (claim 1).
[0006]
In the present invention, a setting block is installed at a substantially central portion in the invisible longitudinal direction, and a panel having a shape that is longer in the vertical direction than in the horizontal direction is placed on the setting block so as to be movable laterally. It is characterized (claim 2).
[0007]
[Action]
In claim 1, when the vertical frame and the incoherence are inclined by the interlayer movement, the side surface portion of the narrow panel that is longer in the vertical direction than in the horizontal direction is relative to the vertical frame in the vertical direction via the holding member. Move to. As described above, since the narrow panel can be moved relative to the vertical frame, it is not necessary to secure a sealing material having a width that allows elastic deformation as in the case of using the sealing material. The sealing material between the panel and the narrow panel can be of a small size, and the vertical frame can be of a small size.
[0008]
In claim 2, when the narrow panel is tilted due to the interlayer movement, the amount of swell of the panel is reduced, and the relative vertical movement between the vertical frame and the panel is reduced by that amount. The clearance to be provided can be reduced.

【The invention's effect】
According to the first aspect, the vertical frame is fixed to the side surface of the wall body so as to be integrated in advance, and is attached between the vertical frames of the adjacent wall bodies, and has a narrow width that is longer in the vertical direction than in the horizontal direction. The narrow panel is placed on the above-mentioned surface through a setting block so as to be laterally movable, and the narrow panel is placed between the both side surfaces of the narrow panel and the vertical frames of the left and right walls. On the other hand, since the holding member that holds the plate so as to move up and down is interposed, the interlayer displacement can be absorbed with a simple structure.
[0025]
According to the second aspect of the present invention, the setting block is installed at a substantially central portion in the longitudinal direction and the narrow panel is placed on the setting block. Therefore, when the narrow panel is inclined by the interlayer movement, The rising amount of the wall body is reduced, and the relative vertical movement amount between the vertical frame and the wall body is reduced accordingly, and the interlayer displacement can be absorbed more efficiently.
