Further, an upper flame shielding plate 18 is provided in the mesh 14 to cover the sliding door supporting member 15 and the suspension wheel 20 from above, thereby further improving the fire prevention performance.
Furthermore, in this fitting, the heating foam material 77 (see FIG. 1) provided at the lower part of the indoor side cover 60 of the mulch 14 foams and expands in the event of a fire, closing the gap between the indoor side flame shielding plate 17, It is possible to prevent flames from entering the blind 14 when a fire breaks out indoors.
The indoor-side cover 60 of the mesh 14 is detachable, and the indoor-side flame shielding plate 17 can be removed by removing the screws 75 and 76 from the indoor side, thereby facilitating maintenance.

As described above, this fitting (embodiment shown in FIGS. 2, 4, and 5) includes vertical frames (door frame 2 and meeting frame 3) and lower frame 4. Lower frame 4 extends in the longitudinal direction. The end surface 42 of the vertical frame 2, 3 is in contact with the inner peripheral side surface 43 of the vertical frame 2, 3, and the vertical frame 2, 3 has a notch 5 in the inner peripheral side surface 43, The heating foam material 6 is continuously provided through the notch 5 over the entire area, and the heating foam material 6 foamed in the event of a fire closes the gap with the lower frame 7 (see FIG. 8). And flames and smoke can be prevented from communicating between the lower frame 4 and the lower frame 7, and the fire prevention performance is improved. A notch 5 is provided in the inner peripheral side surface 43 of the vertical rails 2 and 3, and the heating foam material 6 is continuously provided through the notch 5 over the inside of the lower rail 4 and the insides of the vertical rails 2 and 3. 6 is easy to install.
The heating foam material mounting member (lower rail auxiliary material) 8 is continuously provided across the vertical rails 2 and 3 and the lower rail 4, so that the heating foam material 6 is installed in the lower rail 4 and the vertical rails 2 and 3. It is easy to provide continuously throughout the inside.

This fitting (embodiment shown in FIG. 10) includes vertical frames 2 and 3 and a lower frame 4. The longitudinal end surface 42 of the lower frame 4 abuts against the inner peripheral side surface 43 of the vertical frames 2 and 3. The vertical rails 2 and 3 have heating foam mounting members 9 in the lower hollow portions, and heating foam members 6 are provided in the lower rail 4 and the heating foam mounting members 9 in the vertical rails 2 and 3. A heated foam material 6 foamed in the event of a fire closes the space between the lower frame 7 and the lower frame 7, thereby preventing communication of flames and smoke from the lower parts of the vertical frames 2 and 3 and between the lower frame 4 and the lower frame 7. and improve fire protection performance. Since the heating foaming material attachment member 9 is provided in the hollow part of the lower part of the vertical frames 2 and 3, it is easy to provide the heating foaming material 6 in the vertical frames 2 and 3.

Further, this fitting includes a sliding door 1, a vertical frame 10a, and a vertical frame auxiliary member 11. The vertical frame auxiliary member 11 is provided on the inner peripheral side of the vertical frame 10a, and a groove into which the door tip side of the sliding door 1 is inserted. 12, and heating foam materials 13, 13 are provided on the surfaces facing the outdoor side and the indoor side of the sliding door 1 in the groove 12, so that the door tip portion of the sliding door 1 is prevented from the vertical frame auxiliary member 11 in the event of a fire. Since the heated foam materials 13, 13 foamed in the groove 12 sandwich and hold from the outdoor side and the indoor side (see FIG. 9), flames and smoke can communicate between the door tip of the sliding door 1 and the vertical frame 10a. can be prevented and fire prevention performance is improved. A groove 12 into which the door tip side of the sliding door 1 is inserted is formed in the vertical frame auxiliary member 11 attached to the inner peripheral side surface of the vertical frame 10a, and the heating foam members 13, 13 are mounted in the groove 12, thereby facilitating assembly. Good nature.
Since the vertical frame 10a is used for mounting the sliding door 1 by closing the panel mounting groove 25 with the batten board 27, it is easy to vertically arrange the window part and the part to be opened and closed by the sliding door 1 vertically.

In addition, in this fitting, a sliding door supporting member 15 and a metal flame shielding plate (outdoor flame shielding plate 16, indoor flame shielding plate 17) are provided in the horizontal frame (no mesh) 14, and the sliding door supporting member 15 is , has a suspension rail portion 19, is attached to the vertical frames 10a, 10b or the horizontal frame 14, flame shielding plates 16, 17 are attached to the vertical frames 10a, 10b or the horizontal frame 14, and at least the upper hanging sliding door 1 By covering the hanging wheel 20 and the sliding door support member 15 from the outdoor side and the indoor side, when the horizontal frame 14 is heated from the outdoor side or the indoor side in the event of a fire, the hanging wheel 20 of the upper hanging sliding door 1 and the sliding door are supported. Since the material 15 is protected from flames by the flame shielding plates 16, 17, it is possible to prevent the upper hanging sliding door 1 from falling off, and the fire prevention performance is improved.
Furthermore, this fitting has an upper flame shielding plate 18 in the grommet 14, and covers the suspension wheel 20 of the upper hanging sliding door 1 and the sliding door support member 15 from three sides, ie, the upper side, the outdoor side, and the indoor side, so that the fire prevention performance is improved. Get even better.
Since the sliding door support member 15 has the mounting portion 66 for the engine 65 that drives the sliding door 1, the engine 65 can be stably mounted.
In addition, since the flame shielding plate (indoor flame shielding plate 17) on the side opposite to the base portion 61 of the sliding door support member 15 is detachable, maintenance can be easily performed by removing the indoor flame shielding plate 17.

The invention is not limited to the embodiments described above. The upper hanging sliding door may be manually opened and closed. The shape and material of the flame shield can be changed as appropriate. It may be one that does not have an upper flame shield. The horizontal frame may be the upper frame. The indoor-side flame shielding plate may be stacked on the indoor side of the blind (horizontal frame) and fixed with screws instead of the upper flame shielding plate. INDUSTRIAL APPLICABILITY The present invention can be applied not only to automatic doors for the front of stores and the like, but also to all fittings having overhead sliding doors.
