As described above, the connecting member 1 that connects the plurality of shojis 2 and 3 can form a continuous window with relatively high strength by forming the projection wall 11 in a hollow shape.

Here, in recent years, front sashes are also required to have higher strength and fireproof performance.
In the sash of this embodiment, by efficiently arranging the reinforcing member with respect to the connecting member that connects the shoji, it is possible to increase the strength and improve the fireproof performance without lowering the workability.
A specific configuration will be described below.

The configuration of the connection portion that connects the left and right shojis 2 and 3 of the sash of this embodiment will be described with reference to FIG.
A connecting member (vertical member) 1 includes a prospective wall 11 having a substantially rectangular hollow shape in cross section, left and right indoor side facing walls 12, 12 formed by extending the indoor side walls of the prospective wall 11 to the left and right sides, and a prospective wall. The exterior side wall of the wall 11 has left and right exterior side walls 13, 13 which are formed by extending to the left and right sides.

On both left and right sides of the connecting member 1, shojis 2, 11 are provided by the left and right projection surfaces 11a, 11a of the projection wall 11, the left and right indoor side facing walls 12, 12, and the left and right outdoor side facing walls 13, 13, respectively. Connection grooves 1a, 1a to which vertical frames 23, 34 are connected are formed.

The connecting grooves 1a, 1a of the connecting member 1 have a substantially L-shaped cross section from the indoor side portions of the left and right projection surfaces 11a, 11a of the projection wall 11 to the outdoor side surfaces of the left and right indoor side projection walls 12, 12, respectively. are arranged, and similarly, from the outdoor side portions of the left and right projection surfaces 11a, 11a of the projection wall 11 to the indoor side surfaces of the left and right outdoor side walls 13, 13, respectively. Outdoor reinforcing members 52, 52 having a substantially L-shaped cross section are arranged.

The indoor-side reinforcing member 51 and the outdoor-side reinforcing member 52 of this embodiment have substantially the same length dimension as the longitudinal dimension of the connecting member 1, and are provided over the entire length of the connecting member 1. It is preferable that

The indoor-side reinforcing member 51 and the outdoor-side reinforcing member 52 are arranged along both the left and right projection surfaces 11a, 11a of the projection wall 11 with one side (projection side) 51a, 52a of the L-shape having a predetermined interval, It is fixed by a fixing means b such as a screw, and the other sides (fixed sides) 51b, 52b are the outdoor side (connecting groove side) surfaces of the indoor side fixed walls 12, 12 or the outdoor side fixed walls 13, 13. It is arranged along the indoor side (connecting groove side) surface.

The indoor side surfaces of the left and right indoor side walls 12, 12 of the connecting member 1 are formed flush with the indoor side surface of the side wall 11, and the indoor side reinforcing member 51 of the outdoor side surface of the indoor side side wall 12 is provided. A locking portion 12a is formed on the distal end side of the portion where the is arranged.
Similarly, the outdoor side walls 13, 13 on the left and right of the connecting member 1 are formed flush with the outdoor side of the wall 11, and the indoor side of the outdoor side wall 13 is on the outdoor side. A locking portion 13a is formed on the distal end side of the portion where the reinforcing member 52 is arranged.

On the other hand, the vertical frames 23, 34 of the shoji 2, 3 are formed with glass holding grooves 23b, 34b at approximately the center of the inner peripheral walls 23a, 34a in the prospective direction. It has locking claws 23c and 34c that lock onto the locking portions 12a and 13a.

The vertical frames 23, 34 of the left and right shojis 2, 3 are fixed to the connecting member 1 by inserting the vertical frames 23, 34 into the connecting grooves 1a, 1a of the connecting member 1, and engaging the locking claws 23c, 23c of the vertical frames 23, 34. This can be achieved by locking the 34c to the locking portions 12a and 13a of the connecting member 1. FIG.
If necessary, fixing means such as screws may be added to the engaging portions of the connecting member 1 and the vertical frames 23 and 34 .

Further, the dimensions of the glass holding grooves 23b, 34b of the vertical frames 23, 34 are set to be the same as the dimensions of the indoor side wall 12 and the outdoor side wall 13 of the connecting member 1. , when the vertical frames 23 and 34 are connected to the connecting groove 1a of the connecting member 1, the bottoms of the glass holding grooves 23b and 34b abut or are very close to the projected surface 11a of the projected wall 11 of the connecting member 1. Depending on the situation, the vertical frames 23 and 34 may be firmly fixed to the connecting member 1 by fixing means such as screws through the glass holding grooves 23b and 34b.

As described above, in the sash of the present embodiment, since the connection member has the projection wall having a hollow shape, the strength can be improved. Since the corners are reinforced over the attached wall, twisting and warping of the connecting members (vertical members) can be prevented, and the fireproof performance and strength can be further improved.
In addition, since the reinforcing member for reinforcing the connecting member 1 is arranged outside the hollow portion and is divided into the indoor side and the indoor side, and both the reinforcing members are arranged with a predetermined interval, it is possible to prevent the wall of the connecting member. On the other hand, the workability can be maintained without hindering the direct fixing of the vertical frame and without increasing the overall dimensions.

Furthermore, since the reinforcing members are arranged along the indoor side wall and the outdoor side wall of the connection member 1 that fixes the vertical frame, the reinforcing member can resist the flames from the indoor side and the outdoor side. It is possible to protect the portion where the vertical frame is fixed to the connecting member from the flame.

In addition, the structure of the sash and the vertical frame of the present invention is not limited to the connection member and the vertical frame of the above embodiment.
For example, as shown in FIG. 6, when the vertical frames 23, 34 of the shoji 2, 3 have large projected dimensions, the projected wall 11 of the connecting member 1 may be formed from a plurality of hollow portions 111, 112. FIG.

In addition, although the connecting member 1 of the above embodiment is formed symmetrically about the projection wall 11, the connecting member 1 does not necessarily have to be formed symmetrically. The attachment surface and the indoor-side viewing wall 12 or the outdoor-side viewing wall 13 may be deviated in the direction of projection, and the indoor-side viewing surface or the outdoor-side viewing surface of the connecting member 1 is not formed flush. may

In addition, it goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples.
