Description

  The present invention relates to a sash in which an internal and external shoji is housed in a frame provided in an opening of a building, and more particularly to a sash capable of closing a gap between the frame and the shoji with a foam member even when exposed to a high temperature in the event of a fire.

  In the sash provided in the opening of the building, a sliding sash is widely used, in which internal and external shojis are housed in a frame. A sash including a sliding sash is required to have a fireproof performance that maintains a closed state for a predetermined time or more even when a fire occurs. In order to sufficiently secure the fire prevention performance, it is important not to generate a gap between the frame constituting the sash and the shoji even if the sash is exposed to a high temperature.

  In the sash, not only a resin sash but also a metal sash, resin members are used in various places. Since such a resin member melts when exposed to a high temperature during a fire, it is necessary to maintain the positional relationship between the frame and the shoji even if the resin member melts. In the resin sash, for example, a metal part is provided on each of the frame body side and the shoji side so that they can be engaged with each other in the event of a fire to prevent the shoji from falling off. An example of such a sash is disclosed in Patent Document 1.
