Description

The present disclosure relates to fittings.

Conventionally, in a fireproof sash, the central member in the width direction within the sash frame is easily affected by fire, and is an important member to satisfy fireproof performance. Such a fireproof sash includes, for example, a frame provided in an opening of a building and framed on all sides, and a plurality of shojis supported by the frame so as to be movable from side to side. BACKGROUND ART There is known a four-panel fitting in which two shoji shoji have butt frames and are butted against each other (see, for example, Patent Document 1).

In the case of four-paneled fittings, the butt sections where the butt frames butt together are areas that require fire prevention measures. Patent Document 1 discloses that a plate-shaped metal fitting is provided in the space of the butt part, a heating foam material is provided on the metal fitting, and the heating foam material is heated and foamed even if the resin cover material melts due to a fire. This article describes fittings that are held in place by metal fittings to prevent gaps from forming within the space.

Japanese Patent Application Publication No. 2016-030955

In the fireproof structure shown in Patent Document 1, it is necessary to provide metal fittings in addition to the heated foam material, which increases the number of components and reduces workability, so there is room for improvement in this respect.

In the butt stile of four-walled fittings, the strength of the left and right butt stile is the same, so the warpage in the out-of-plane direction is the same, making it difficult for gaps to open due to warp. On the other hand, unlike abutting stile, abutting stile is not restrained in the in-plane direction by hardware, so there is a risk that the vertical center will warp in the in-plane direction, creating a gap between the two abutting stile. There was a problem that fire protection performance deteriorated.

The present disclosure provides fittings that can realize a simple structure by reducing the number of members, improve workability, and improve fire prevention performance.
