DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which panel units adjacent to the left and right sides of a curtain wall having panel units attached to right and left adjacent cubicles are erected.

[0002]

2. Description of the Related Art As a structure for mounting panel units of a curtain wall on right and left sides adjacent to each other, for example, as shown in Japanese Utility Model Laid-Open Publication No. 3-73315, sealing materials are attached to the left and right sides of the cubic outdoor side, respectively. The left and right seal members are attached by crimping the inner surfaces of the left and right panel units inside the vertical frame, or as shown in Japanese Utility Model Laid-Open Publication No. 64-41509, the reinforcing bracket can be pivoted in the in-plane direction. It is known that a vertical frame of a panel unit is connected to this reinforcing bracket, and a sealing material is attached to the vertical frames of the panel units adjacent on the left and right sides and pressed against each other.

[0003]

As a curtain wall, there is known a curtain wall in which a plurality of panel units are attached in a curved shape or a polygonal shape in the left-right direction. In such a curtain wall, the gap between the vertical frames of the left and right panel units, that is, the shape of the joint is narrower on the indoor side and wider on the outdoor side.
The joint size differs depending on the radius of the curved surface, the angle of the polygon, and the like.

For this reason, the structure in which the sealing material is mounted on the vertical frame as described above and the joint is sealed by abutting the sealing material cannot sufficiently abut the sealing material when the joint size is large. Not only can't be sealed securely, and the joint size on the outdoor side becomes large and the appearance deteriorates.In addition, when the radius of the curved surface and the angle of the polygon are different in one curtain wall, joints with different joint sizes are visible, so the appearance is good. It will be very bad. On the other hand, when the joint size is small, the sealing material may be compressed more than necessary and the sealing material may be damaged.

Accordingly, an object of the present invention is to provide a curtain wall panel unit mounting structure capable of solving the above-mentioned problems.

[0006]

A panel unit 3 is mounted on a frame 8 comprising an upper frame 4, a lower frame 5, a left vertical frame 6, and a right vertical frame 7 having a projecting member 50 on the outdoor side. The left vertical frame 6 and the right vertical frame 7 of the left and right panel units 3 and 3 are connected to the left and right outdoor side mounting portions 23 of the cubicle 1 by fasteners 41, respectively. The projecting member 50 is made to protrude outside the joint from the joint B between
And a spacer 43, a washer 47 and a nut 48,
Arc surface 43a of spacer 43 and arc surface 4 of washer 47
7a is the outdoor side surface 23a of the outdoor side mounting portion 23, the indoor side surface 2
3b, a left sealing material 60 having an L-shaped planar shape is attached to the left vertical frame 6 near the outdoor side by first and second vertical pieces 61 and 62, and the right vertical frame 7 has an outdoor side. Closer first
A curtain wall panel unit mounting structure in which the right sealing material 70 having an L-shaped planar shape is mounted by the second vertical pieces 71 and 72, and the joints B are sealed by pressing the vertical pieces of the left and right sealing materials 60 and 70. .

[0007]

[Operation] The left vertical frame 6 of the right panel unit 3 and the right vertical frame 7 of the left panel unit 3 can be connected to the left and right outdoor mounting portions 23 of the cubicle 1 by swinging left and right. By adjusting the mounting angle of the panel unit 3, the plurality of panel units can be mounted in a curved shape or a polygonal shape in the left-right direction, and the plane between the left vertical frame 6 and the right vertical frame 7 of the left and right panel units 3 is substantially c. When the size of the joint B in the shape of a letter or an inverted letter C changes, the first and second vertical pieces 61 and 62 of the left sealing material 60 are changed.
Since the first and second vertical pieces 71 and 72 of the right seal member 70 are elastically deformed and are always pressed against each other, the joint B can be reliably sealed, and the left and right vertical frames 6 of the left and right panel units 3 can be sealed. Since the protruding member 50 protrudes to the outside of the room from the joint B between the right vertical frame 7 and the joint B, the size of the joint B is reduced by the protruding member 50 to increase the joint size. The appearance does not deteriorate, and the projection member 50 reduces rainwater blowing into the joints B, so that rainwater can be reliably prevented from entering the room from the joints B, and the sealing members 60 and 70 are damaged. There is no.

Are pressed against the indoor side surface 23b of the outdoor-side mounting portion 23, respectively, and the left vertical frame 6 is connected to the cubic 1 so as to be able to swing left and right.

As shown in FIG. 4, the right vertical frame 7 is formed by integrally providing a projecting member 50 at the outdoor end of a main body 7a having substantially the same cross-sectional shape as the left vertical frame 6. Is substantially L-shaped by a projecting piece 51 and an L-shaped piece 52 provided integrally at the outdoor end of the main body 7a, and has a concave portion 53 opened to the indoor side on the outdoor side. Bezel 3
9 and the left and right vertical frames 6, 7
It is located at the left and right middle part of the joint B between them. That is, the joint B is constituted by the pressing edge 39 of the left vertical frame 6 and the projecting member 50 of the right vertical frame 7. Note that the pressing edge 39 may be provided integrally with the left and right vertical frames 6 and 7.

A left sealing material 60 is mounted on the outdoor outward concave groove 33 of the left vertical frame 6, and a right seal material 70 is mounted on the outdoor external concave groove 33 of the right vertical frame 7. As shown in FIG. 7, the left sealing material 60 is a first vertical piece 6 facing in an out-of-plane direction.
1 and the second vertical piece 62 facing in the in-plane direction becomes a long material having an L-shaped cross section, and the right sealing material 70 is the first vertical piece 71 facing in the out-of-plane direction.
And the second vertical piece 72 facing the in-plane direction becomes a long material having an L-shaped cross section, and the second vertical pieces 62 and 72 of the left and right seal materials 60 and 70 are in the free state as shown by phantom lines in FIG. First vertical piece 6
The first vertical pieces 62 and 72 are elastically deformed to substantially 90 degrees by being pressed against the end faces 61a and 71a of the first vertical pieces 61 and 71 when the second vertical pieces 62 and 72 are mounted. Therefore, even if the size of the joint B between the left vertical frame 6 and the right vertical frame 7 changes at an angle, the left and right seal members 6
The joints 0 and 70 can reliably seal the joint B by being pressed against each other.

As shown in FIGS. 3 and 4, a joint bar 54 is provided in the recess 53 of the projecting member 50 of the right vertical frame 7 with a screw 5.

When the dimension of the joint B in the plane between the left vertical frame 6 and the right vertical frame 7 of the left and right panel units 3 becomes substantially C-shaped or inverted C-shaped, the first and second sealing materials 60 of the left sealing material 60 are changed. Since the vertical pieces 61, 62 and the first and second vertical pieces 71, 72 of the right sealing material 70 are elastically deformed and are always pressed against each other, the joint B can be reliably sealed. Left vertical frame 6 and right vertical frame 7 of left and right panel units 3
Since the protruding member 50 protrudes to the outside of the room from the joint B, the size of the joint B is reduced by the protruding member 50 to increase the joint size, and the appearance deteriorates even when the joint size is different. And the projecting member 5
By setting the value to 0, it is possible to reduce rainwater blowing into the joint B, and it is possible to reliably prevent rainwater from entering the room from the joint B.
