  Generally, in a heat insulating shoji, as shown in FIG. 7, a face glass (5) having a pair glass structure, for example, is placed in a shoji frame (4) in which heat insulating rods (1), (2), (3). Is inserted. And, as shown in FIG. 8, for example, the heat insulating rods (1), (2), (3)... Are made of a metal insulating material (6) on the outdoor side and a metal metallic material (7) on the indoor side from a heat insulating resin. It becomes the structure connected through the heat insulating material (8) and (8) which become.

  In the case of such a heat insulating shoji, when a fire occurs and the heat insulating materials (8) (8) are softened or melted, for example, the face material mounting groove (9) into which the end of the face material (5) is fitted is deformed. There is a danger that the face material (5) will fall off due to the metal casings (7), (7).

  Therefore, the face material drop prevention tool (10), (10), which is excellent in heat resistance, is provided on the shoji frame (4), and the edge of the face material (5) is provided by the face material drop prevention tool (10), (10), ... There is a fire-proof specification that prevents the face material (5) from falling off in the event of a fire by supporting the part.

  The face material fall-off prevention tools (10), (10) are formed in an L shape or a U-shape, and, for example, in the face material mounting groove (9) of the shoji frame (4), for example, the heat insulating rod (1) (2) (3) ... Screws (12), (12) ... are often attached by stoppers at 8 places in total, 2 places per one.

  However, since such a heat-insulated shoji is about 30% of the heat-insulating shoji to be produced, it is costly to automate the installation of the face material fall-off prevention tool (10) (10)… There is a problem, and the face material dropout prevention tools (10), (10), etc. are attached mainly by manual work.

  However, a plurality of dedicated screw holes are made in the narrow face material mounting groove (9) in the shoji frame (4), so that the face material fall-off prevention tools (10), (10) are replaced with screws (12), (12). It was very troublesome and time-consuming to install.

  Therefore, as disclosed in, for example, Patent Document 1, by using an existing screw hole formed in a heat insulating frame of a shoji frame, a part of this screw hole is widened or cut, and a face material falling prevention tool is provided. There is one that does not need to screw the face material fall-off prevention tool by attaching it directly.
