According to the second embodiment, as shown in FIG. 15 (b), the hollow portion mounting bracket 44 provided at the lower end portion of the collar frame 13 a is formed on the lateral frame side surface 44 a that faces the prospective surface 11 f of the lower frame 11. Since the seventh thermal expansion refractory material 32g is provided, when the seventh thermal expansion refractory material 32g expands in the event of a fire, between the lower side of the hollow portion mounting bracket 44 and the upper surface of the lower frame 11 in the hollow portion 12. Thereby, the abutting portions 8a, 8b, 8c of the lower frame 11 and the hollow portion 12 of the port side frame 13a, the outdoor small opening 12c of the inner peripheral wall 12b of the hollow portion 12, and the lateral chamber of the lower frame 11 Since the space P of the outer side finding wall 10b can be blocked, it is possible to prevent the flames and smoke from being ejected from the butted portions 8a, 8b, 8c and the space P. In addition, since the 14th thermal expansion refractory material 32m provided in the lower frame 11 has entered the inside of the hollow portion 12, the seventh thermal expansion refractory material 32g is in contact with each other by thermal expansion in the hollow portion 12 during a fire. It assists to block the portions 8a, 8b, 8c and the space P.
In particular, even when a gap occurs in the butted portions 8a, 8b, and 8c of the saddle frame 13a and the lower frame 11 due to the warp frame 13a being warped due to thermal expansion during a fire, the gap can be blocked.
As shown in FIGS. 12 and 13, the shoji 5 is provided with a seventeenth thermal expansion refractory material 32 r on each glass holding groove reinforcing material 53 provided on the upper heel 17, the lower heel 19, and the left and right ridges 21 a, 21 b. Therefore, in the event of a fire, the space between each fence 17, 19, 21a, 21b and the glass 4 is closed, and the interior and exterior of the glass 4 communicate with each other around the glass 4 so that flames and smoke enter the indoor side, or blow out from the indoor side. Can be prevented.
In addition, since the setting rod 71 made of aluminum is provided on the glass holding groove reinforcing material 53 in the lower rod 19, the glass 4 is prevented from lowering even if the glazing gasket 49 is melted in a fire. Can be kept stable.

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 a vertically sliding sash or an inward sash, but a sash in which a shoji 5 is supported by a frame 3 such as an outwardly sash, a sliding sash, an open sash, a rotating sash, a sliding door, It may be a door. 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 but may be made of a non-combustible material, and preferably are made of a material having heat resistance equal to or higher than that of aluminum. .
In the first embodiment, the lower door end side mounting bracket 41 may be provided at each corner portion of the frame 3 so that the butted portion 8 of each corner portion is closed with the fourth thermal expansion refractory material 32d.
In 2nd Embodiment, even if the hollow part attachment metal fitting 44 closes the butt | matching part of the upper frame 9 provided in the upper end part of each left and right collar frame 13a, 13b, and each collar frame 13a, 13b. good.
