  In the first embodiment and the second embodiment, the 17th thermal expansion refractory material 32s used in the second embodiment is provided in a place where heat is not easily transmitted. Other thermal expansion refractory materials, that is, the first thermal expansion refractory material 32a to the sixteenth thermal expansion refractory material 32r, the eighteenth thermal expansion refractory material 32t, and the nineteenth thermal expansion refractory material 32u. A general thermal expansion body (initiating expansion at about 200 ° C.) is used.

Next, the effect of the fitting 1 concerning 2nd Embodiment is demonstrated.
As in the first embodiment described above, in the event of a fire, the shojis 21a, 21b of the shoji 5 are extended by the heat of the fire, and when the shoji 5 is lowered, the shoji mount projecting upward from the upper surface of the lower frame 11 The placement unit 6a places the lower eyelid 19 to prevent the shoji 5 from greatly falling and falling off.
Since the shoji receiver 6 protrudes from the upper surface of the lower frame 11 and narrows the space between the shoji lower arm 19, the ventilation from the lower end of the shoji can be suppressed during a fire.
Moreover, when the heat at the time of a fire is received, the 1st thermal expansion refractory material 32a provided in the shoji receiver 6 expands, and the gap with the lower arm 19 of the shoji 5 is closed, and a flame gushes from the shoji under side to the outdoor side. Can be prevented.

Furthermore, according to the second embodiment, as shown in FIGS. 12 and 13, the finding wall 71b of the locking member 71 is positioned above the prospective wall 73b of the receiver 73 and on the indoor side in a normal state. Both are located at a distance, and do not get in the way when opening and closing the shoji 5.
As indicated by the two-dot chain line E in FIG. 12 and the two-dot chain line in FIG. 4, in the event of a fire, when the eaves 21 a and 21 b of the shoji 5 are extended by the heat of the fire, the finding wall 71 b of the locking member 71 is The shoji 5 is prevented from warping by facing the indoor side of the prospective wall 73b and locking it from the indoor side. Thereby, the shoji 5 is prevented from separating from the lower frame 11 to the outdoor side due to the warp of the shoji 5 and from the gap between the shoji 5 and the frame 3.
Further, as shown by a two-dot chain line F in FIG. 12, when the finding wall 71 b of the locking member 71 is placed on the upper end of the prospective wall 73 b of the receiver 73, it is possible to prevent the shoji 5 from being lowered and Since the movement of the finding wall 71b of the locking member 71 to the outdoor side is restricted by the frictional resistance, the shoji 5 can be prevented from warping.
Further, even if there is a variation in the degree of thermal expansion between the flanges 21a and 21b, the finding wall 71b of the locking member 71 provided on the flanges 21a and 21b and the prospective wall 73b of the receiver 73 are shown by the two-dot chain line in FIG. By being locked from the indoor side as shown by E or by being placed as shown by the two-dot chain line F in FIG. 12, it is possible to prevent warpage due to the difference in thermal expansion of the flanges 21a and 21b.

In the locking member 71, the fixing portion 71a is fixed to the aluminum-shaped rods 21a and 21b, and the covering surface 71c covers the prospective surface of the resin-shaped member 76. When 76 is burned off, when the lower part of the shoji 5 is viewed from the outdoor side, the covering portion 71c of the locking member 71 blinds the gap between the saddle frame 13 and the shoji 5 and prevents an increase in ventilation. it can.
As shown in FIG. 17, the fourteenth thermal expansion refractory material 32 p provided on the indoor side walls 13 d of the left and right eaves frames 13 a, 13 b is sandwiched between the indoor side walls 13 d of the eaves frames 13 a, 13 b and the shoji support member 7. Therefore, the 14th thermal expansion refractory material 32p can be easily attached and the 14th thermal expansion refractory material 32p can be prevented from falling.

Each glass holding groove reinforcing member 53 is provided with a seventeenth thermal expansion refractory material 32 s facing the end faces of the four circumferences of the glass 4. Since the space between the glass end faces is closed, it is possible to prevent the indoor flame from being ejected from between the glass holding groove reinforcing material 53 and the glass 4.
Moreover, the 16th thermal expansion refractory material 32r provided in each glass front corner metal fitting 87 closes between the glass front corner metal fitting 87 and the glass holding groove reinforcing material 53 at the time of a fire. In the left and right cages 21a and 21b, the eighteenth thermal expansion refractory material 32t provided on the indoor side of the glass holding groove 51 closes between the glass holding groove reinforcing material 53 on the indoor side of the firewood 21 in the event of a fire. Prevents the flames from blowing out.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
For example, the joinery 1 is not limited to an overturned sash, and is a sash or door that is supported by a frame 3 such as a sliding sash, a vertical sliding sash, an open sash, or a rotating sash, so that the shoji 5 can be opened and closed. Also good. When the joinery 1 is a door, the shoji 5 is a door body.
The lower door end side mounting bracket 41 and the hollow portion mounting bracket 44 are not limited to steel and are not particularly limited as long as the melting point is higher than that of aluminum.
The lower door end side mounting bracket 41 may be attached to each corner portion of the frame 3.
In the first embodiment, as in the second embodiment, the locking member 71 may be provided only on the opening side ridge, and the receiver 73 may be provided on the lower frame 11 at a position facing the locking member 71.
