BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grit curtain wall joint structure in which glass or the like is fitted.
More specifically, the distance between the joints is reduced.

[0002]

2. Description of the Related Art Curtain walls include so-called grit curtain walls into which glass or the like is fitted. Adjacent ones of this grit curtain wall are joined to each other and attached to the skeleton side, similarly to a general one. FIG. 3 is a front view of a conventional grit curtain wall,
FIG. 4 is a cross-sectional view showing a joint structure of a conventional grid curtain wall. As shown in FIG. 3, the conventional grit curtain wall 1 has a single unit frame 3.
Are connected by a joint portion 5. As shown in FIG. 4, a glass frame 7 is provided on the front side (the side opposite to the frame) of the unit frame 3, and a glass 9 is attached to the glass frame 7. A mounting hole is formed on the back surface side (frame side) of the unit frame 3, and the unit frame 3 is mounted on the frame 13 side by bolts 11 inserted into the mounting holes.

An edge 15 is formed on the outer periphery of the unit frame 3 so as to protrude, and the unit frames 3 are connected by bringing the edges 15 into contact with each other. A connecting material or the like is sandwiched between the contact surfaces of the edge portions 15, and the exposed portion on the front (found) side is covered with a sealing material 17. Accordingly, the joint portion 5 of the unit frames 3 is such that the glass frame 7, the edge portion 15, and the sealing material 17 are exposed between the adjacent glasses 9.

[0004]

However, in the conventional grit curtain wall joint structure, since the glass frame 7, the edge 15, and the sealing material 17 are exposed between the adjacent glasses 9, the appearance at the joint is not sufficient. The additional dimension d (see FIG. 4) was increased, and in particular, in the unit frame 3 having a large lateral width, the joint portion 5 was conspicuous, and the aesthetic appearance of the entire grid curtain wall could be impaired.

The present invention has been made in view of the above situation, and has a joint structure of a grit curtain wall that can reduce the apparent size at a joint without exposing a glass frame and an edge between adjacent glasses. It is an object of the present invention to provide an aesthetic appearance.

[0006]

In order to achieve the above object, the construction of the joint structure of the grit curtain wall according to the present invention comprises a joint of the grit curtain wall for fixing the glass frames of the adjacent unit frames on the right and left sides. When the unit frames are adjacent on the left and right,
Opposing side plates are formed on the respective glass frames, and mounting flanges for fixing the glass frames vertically are projected outside the side plates, and when connecting the left and right unit frames, the mounting flange of one unit frame is connected. The mounting flanges and the cutouts are alternately arranged in the reverse order on the side plates facing each other so as to be inserted into the cutouts of the other unit frame, and coincide with the respective mounting flanges and cutouts. The mounting flange and the notch are formed in a rectangular shape.

[0007]

When the left and right unit frames are connected to each other, the mounting flanges of one unit frame are inserted into the cutouts of the other unit frame, and the right and left mounting flanges are alternately arranged in the vertical direction. The unit frames are connected to each other at the gap, and the gap between the unit frames, that is, the apparent size of the joint portion is extremely small.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the joint structure of a grit curtain wall according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing the joint structure of the grit curtain wall according to the present invention, and FIG. 2 is a view taken along the line AA of FIG. In the joint structure of the grit curtain wall according to the present invention, the upper frame and the lower frame (not shown) are fixed to the upper and lower end surfaces of the left and right cubicles provided therebetween by a tapping screw to form the unit frame 21. ing. Glass frames 23 extending in the vertical direction are provided on the left and right of the unit frame 21, and when the unit frames 21 are adjacent to each other on the left and right, the side plates 23a are opposed to each other with a slight gap. .

A contact plate 23b, which is parallel to the glass 25, protrudes from the inside of the side plate 23a.
7. It is fixed to the side plate 23a and the contact plate 23b via the sealing material 29. A mounting flange 23c is formed to protrude outside the side plate 23a (opposite to the contact plate 23b), and cutouts 23d are formed in the mounting flange 23c at regular intervals in the vertical direction. That is, as shown in FIG. 2, the mounting flanges 23c are arranged alternately with the notches 23d. The mounting flange 23c and the notch 23d are disposed on the left and right side plates 23a in the reverse order of the vertical relationship. When the unit frame 21 approaches the left and right, the mounting flange 23c of one unit frame 21 is connected to the other unit frame 21. (See the mounting flange 23c shown by a broken line in FIG. 2).

The mounting flanges 23c and the cutouts 23d are formed on the cubicles 31 corresponding to the respective unit frames 21. The mounting flanges 31c and the cutouts 31d are formed on the front side of the unit frame 21. And is fixed to the mounting flange 31c with screws 33 inserted between the side plates 23a. Accordingly, by fixing the mounting flange 23c to the mounting flange 31c, the unit frame 21 to which the glass 25 is fixed is fixed to the cubic 31.
It is fixed to

In the joint structure of the grid curtain wall thus configured, when the unit frames 21 are adjacent to each other on the left and right, the mounting flange 23c of one unit frame 21 is inserted into the cutout 23d of the other unit frame 21. The left and right mounting flanges 23c are alternately arranged in the up-down direction, and there is no need to mount adjacent mounting flanges 23c at intervals in the horizontal direction.
The unit frames 21 are connected to each other with a slight gap of c. After the unit frames 21 are attached adjacent to each other,
The cushioning material 27 is sandwiched between the two gaps, that is, between the side plates 23a, and the sealing material 29 is coated, and only a small gap is exposed at the joint between the adjacent glasses 25. Only the sealing material 29 is used, and the apparent size D of the joint portion is extremely small.

According to the above-described joint structure of the grit curtain wall, the joint portion between the adjacent unit frames 21 can have the minimum apparent size D, and the joint portion is not conspicuous and impairs the aesthetic appearance of the entire grid curtain wall. There is no. Further, in the present embodiment, since the glass frame 23 can be fixed using the joint joint, it can be used even when the mounting operation from the back side cannot be performed, which is extremely practical.

[0013]

As described in detail above, the joint structure of the grit curtain wall according to the present invention is such that when connecting the left and right unit frames, the mounting flange of one unit frame is inserted into the notch of the other unit frame. To be,
Since the mounting flanges and notches are arranged alternately in the vertical direction, when the unit frames are connected, the left and right mounting flanges are alternately arranged in the vertical direction, and the unit frames are separated by a gap of one mounting flange. It is possible to make the gap between the unit frames connected, that is, the apparent size of the joint portion extremely small. As a result, it is possible to prevent the appearance of the joint portion of the grit curtain wall from being deteriorated.
