[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a joint structure of a grit curtain wall into which glass or the like is fitted, and more specifically, to reduce the distance between the joint portions.

[0002]

[Prior Art]

 The curtain wall has a so-called grit curtain wall into which glass or the like is fitted. Similar to general grit curtain walls, adjacent grit curtain walls are jointed together and attached to the body side. FIG. 3 is a front view of a conventional grit curtain wall, and FIG. 4 is a transverse sectional view showing a joint structure of a conventional grit curtain wall. As shown in FIG. 3, in the conventional grit curtain wall 1, each unit frame 3 is connected by a joint portion 5. As shown in FIG. 4, a glass frame 7 is provided on the front side of the unit frame 3 (the side opposite to the body), 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 body 13 side by a bolt 11 inserted in the mounting hole.

An edge portion 15 is formed so as to project on the outer periphery of the unit frame 3, and the unit frame 3 is connected by bringing the edge portions 15 into contact with each other. A connecting material or the like is inserted into the contact surface of the edge portion 15, and the exposed portion on the front (finding) side is covered with the sealing material 17. Therefore, in the joint portion 5 between the unit frames 3, the glass frame 7, the edge portion 15, and the sealing material 17 are exposed between the adjacent glasses 9.

[0004]

[Problems to be solved by the device]

 However, in the conventional joint structure of the grit curtain wall, the glass frame 7, the edge portion 15, and the sealing material 17 are exposed between the adjacent glasses 9, so that the found size d at the joint portion (see FIG. 4) is The joint part 5 was conspicuous in the unit frame 3 having a large width, and the horizontal width was particularly large, which might impair the aesthetics of the entire grit curtain wall.

The present invention has been made in view of the above circumstances, and is a grid curtain wall that can reduce the size of the joint at the joint portion without exposing the glass frame and the edge portion between the adjacent glass portions. The purpose of the joint structure is to prevent the deterioration of aesthetics.

[0006]

[Means for Solving the Problems]

 The structure of the joint structure of the grit curtain wall according to the present invention for achieving the above object is a joint structure of the grit curtain wall for vertically fixing the glass frames of the unit frames that are adjacent to each other on the left and right. When they are adjacent to each other on the left and right sides, opposite side plates are formed on each glass frame, and a mounting flange for vertically fixing the glass frames is projected on the outside of the side plates. The mounting flanges of the unit frame and the notches are alternately arranged in the vertical direction in the opposite order on the side plates facing each other so that the mounting flanges are inserted into the notches of the other unit frame. It is characterized in that the mounting flange and the notch corresponding to the notch and the notch are formed upright.

[0007]

[Action]

 When the left and right unit frames are connected, the mounting flanges of one unit frame are inserted into the notches of the other unit frame, the left and right mounting flanges are arranged alternately in the vertical direction, and there is a gap for one mounting flange. The unit frames are connected with each other, and the space between the unit frames, that is, the joint dimension is extremely small.

【Example】

 Hereinafter, a preferred embodiment of a joint structure for a grit curtain wall according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing a joint structure of a grit curtain wall according to the present invention, and FIG. 2 is a view taken along the line AA of FIG. In the grit curtain wall joint structure according to the present invention, the upper frame and the lower frame (not shown) are fixed to the upper and lower end faces of the left and right vertical sides provided therebetween by tapping screws to form the unit frame 21. ing. Vertically extending glass frames 23 are provided on the left and right sides of the unit frame 21, and when the unit frames 21 are adjacent to each other on the left and right sides, the side plates 23a face each other with a slight gap therebetween. There is.

A contact plate 23b, which is parallel to the glass 25, is formed so as to project inside the side plate 23a. The glass 25 is fixed to the side plate 23a and the contact plate 23b through a cushioning material 27 and a sealing material 29. Has become. Mounting flanges 23c are formed so as to project from the outside of the side plate 23a (on the side opposite to the contact plate 23b), and notches 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 cutouts 23d. The mounting flange 23c and the notch 23d are arranged on the left and right side plates 23a in the opposite order of the vertical relationship. It is designed to be inserted into the notch 23d of the frame 21 (see the mounting flange 23c in the broken line portion in FIG. 2).

Further, a mounting flange 23 c, a mounting flange 31 c corresponding to the cutout 23 d, and a cutout 31 d are also formed on the upright 31 corresponding to each unit frame 21, and the mounting flange 23 c is on the front side of the unit frame 21. It is adapted to be fixed to the mounting flange 31c by a screw 33 inserted between the side plates 23a. Therefore, the mounting flange 23c is fixed to the mounting flange 31c, so that the unit frame 21 to which the glass 25 is fixed is fixed to the upright 31.

In the joint structure of the grit curtain wall configured as described above, when the unit frames 21 are laterally adjacent to each other, the mounting flange 23c of the one unit frame 21 is aligned with the notch 23d of the other unit frame 21. Inserted, the left and right mounting flanges 23c are alternately arranged in the vertical direction, and it is not necessary to horizontally attach adjacent mounting flanges 23c to each other, and a unit frame with a slight gap for one mounting flange 23c is provided. 21 are connected to each other. After the unit frames 21 are mounted adjacent to each other, the cushioning material 27 is inserted between the two, that is, the side plates 23 a, and the sealing material 29 is coated between the adjacent glass 25. Only the sealing material 29 coated in the slight gap is exposed at the joint portion, and the found dimension D of the joint portion is extremely small.

According to the joint structure of the grit curtain wall described above, the joint portion between the adjacent unit frames 21 can have a minimum found dimension D, the joint portion is inconspicuous, and the appearance of the entire grit curtain wall is improved. Will not hurt. Further, in this embodiment, since the glass frame 23 can be fixed by utilizing the joint joint, it can be used even when the mounting work from the back side cannot be performed, and is extremely practical.

[0013]

[Effect of the device]

 As described in detail above, the joint structure of the grit curtain wall according to the present invention allows the mounting flange of one unit frame to be inserted into the notch of the other unit frame when connecting the left and right unit frames. Since the mounting flanges and the notches are alternately arranged in the upper and lower directions, when the unit frames are connected to each other, the left and right mounting flanges are alternately arranged in the vertical direction, and the unit frame has a gap for one mounting flange. Since they are connected to each other, the gap between the unit frames, that is, the joint dimension can be made extremely small. As a result, it is possible to prevent the aesthetic deterioration of the joint portion of the grit curtain wall.
