11, 30, 31, 60, and 61, and are formed with projecting portions 10c, 30c, and 60c having the same shape at the end portions of each indoor side wall.

Since it is like this, the upper frame 1, the vertical frame 3, and the lower frame 2
It is possible to cut the frame 3 and the vertical frame 3 at 45 degrees and connect them by butt welding, but since they are simply connected by welding, the connection strength will be weak.

Therefore, as shown in Fig. 5, upper frame 1 and lower frame 2 are
Both ends of the vertical frame 3 are cut at 45 degrees, and the 45 degree cut end surfaces 1a, 2a, 3a are butted and welded together, and the indoor wall 10 of the upper frame 1 and the indoor wall 6 of the vertical frame 3 are
0 and the indoor side wall 30 of the lower frame 2 and the indoor side wall 60 of the vertical frame 3 to reinforce each corner connecting part, and
A screw 81 is passed through the L-shaped stopper 80 from the projecting portions 10c, 30c, and 60c of 0.0 and 60, and is screwed into the outer surface _D1 of the building frame.

In other words, the L-shaped stopper 80 has a horizontal piece 82 and a vertical piece 8.
3, it becomes an L-shaped plate shape, and each indoor wall 10,
Both ends of the leg pieces 18, 51, 68 formed on the legs 30, 60 are cut off, and the horizontal piece 82 and the vertical piece 83 of the L-shaped stopper 80 are attached to the cut parts, and
It is connected to the reinforcing members 22, 56, and 72 by screws 84, respectively.

Because of this, the strength of the connecting portion of the frame can be increased, and the strength of attachment of the frame to the building frame can be increased.

The upper stile 4 and the lower stile 5 are the indoor/outside walls 4a, 4.
b, 5a, 5b to upper and lower connecting walls 4c, 4d, 5c,
5d, hollow parts 4', 5' and upper and lower recessed parts 4'',
4, 5'', 5, and the indoor/outside walls 4a, 4b, 5a, 5b are double walls and have hollow parts, and each of the hollow parts 4',

It is fixed to the bottom surface with screws 98.

Because of this, the weight of the glass 8 is transmitted to the lower inner and outer rails 42 and 43 via the setting block 99, the connecting wall 5c in the lower stile, the lower reinforcing cross member 91, the housing 93 of the door roller 92, and the wheels 94. Shi, lower stile 5
Since the weight of the glass 8 does not act on the lower frame 5, which is made of synthetic resin and has low rigidity, it will not be deformed.

The door frame 6 and the door frame 7 are connected to the indoor/outside walls 6a, 6b, 7a, 7b and the inner/outside connecting walls 6c, 6.
d, 7c, and 7d form a shape having hollow parts 6', 7' and inward recesses 6'', 7'', and the hollow parts 6',
A reinforcing vertical member 99 made of steel is inserted into the inner wall 7'.

The end faces of the upper and lower frames 4 and 5 are abutted against the step 6e of the doorstop frame 6 and the step 7e of the matching frame 7, and the upper and lower reinforcing cross members 90 and 91 extend outward from the upper and lower frames 4 and 5. It protrudes, and its end surfaces are connected to each inner connecting wall 6c, 7c.
The screw 9 is in contact with the reinforcing vertical member 99.
9a are screwed into screw holes 90e and 91e to connect the upper and lower frames 4 and 5 to the door stop frame 6 and the door frame 7.

Because it is like this, the upper and lower frames made of synthetic resin 4,
5 and the doorstop stile 6 and the matching stile 7 can be firmly connected via upper and lower reinforcing horizontal members 90, 91 and right and left reinforcing vertical members 99.
