The outer sash 7 of the indoor side fitting B2 will be described below. However, since the outer sash 7 and the inner sash 6 have basically the same configuration, the same configuration as that of the inner sash 6 will be described. , The explanation is omitted.

As shown in FIG. 8, the combination (right vertical) stile 79 of the shoji 7 has a right vertical stile main body 791 made of a resin material.
The right vertical frame main body 791 has a right vertical frame main body portion 791a having a hollow portion and a panel frontage 791b formed on the inner peripheral side of the right vertical frame main body portion 791a.

Further, a heating expansion material f96 that expands due to heating in the event of a fire is arranged on the first reinforcing member 792.

In the above other embodiments, the indoor side fitting B2 arranged on the indoor side of the building opening is made of a resin material, and the upper frame 56, the lower frame 57, and the inner circumferences of the left and right vertical frames 58 and 59 are made of metal. A rail member or a reinforcing member made of a material is arranged to form a frame body, and the frame body is fixed to the building opening with a heating expansion material interposed between the frame body and the building opening. Therefore, in the event of a fire, the heat-expanding material that is interposed between the building opening and the building expands, and the frame is deformed and melted by the heat of the fire, closing the gap between the building opening and the frame. The skeleton at the opening of the building can be protected and the spread of fire can be suppressed.
The heat-expanding material placed between the frame and the opening of the building is not placed on the entire outer peripheral surface of the frame, but is placed on two rows, one on the outdoor side and the other on the indoor side. It is possible to prevent the frame from being deformed due to excessive expansion.

Further, in the indoor side fittings B2, the outer sashes 6 and 7 have a reinforcing core material or a reinforcing member made of a metal material inside the upper stile main body and the lower stile main body and the left and right vertical stile main bodies made of a resin material. The reinforcing core material and the reinforcing member are connected to each other by a connecting means, and a heat expansion material is arranged at an appropriate portion of the reinforcing core material and the reinforcing member.
In particular, a reinforcing member having a substantially U-shaped cross section that opens toward the outer peripheral side is arranged on the vertical frame main body of the door tip frame facing the vertical frame, and heat expansion is performed on three surfaces of the inner peripheral surface of the reinforcing member. The materials are arranged.
Therefore, the heat-expanding material expands at an early stage in response to a fire from either the indoor side or the outdoor side, and the heat-expanding material expanded on the inner circumference of the reinforcing member is on the outer peripheral side, that is, the vertical frame or the reinforcing member 582. Since it expands toward 592, even if the main body of the door end stile made of a resin material melts and disappears, the space between the shoji and the frame can be reliably sealed.

Furthermore, in the vertical frame (left vertical frame) on the side where the outer sash is placed when the fitting is closed, a reinforcing member and a heat expansion material are placed on the outdoor side of the central wall of the vertical frame, and the inner sash is placed when the fitting is closed. In the vertical frame on the side to be arranged (right vertical frame), the reinforcing member and the heat expansion material are arranged on the indoor side surface of the central wall of the vertical frame, and the heat expansion material arranged in the left and right vertical frames is the vertical frame. In addition to being placed near the center position in the prospective direction, in the upper and lower frames, the heating expansion material having indoor and outdoor rails and the heating expansion material placed between the inner and outer rails of the lower rail member is placed in the upper and lower frames. By arranging the upper and lower frames near the center position in the prospective direction, a fire protection line that blocks the space between the frame body and the inner and outer shoji screens in the event of a fire is continuously formed on four circumferences at the central position in the prospective direction of the frame body. be able to.
Therefore, even if the frame or frame made of resin material melts in the event of a fire, the heat expansion material expands so as to wrap the connected reinforcing core material and reinforcing member, and the shapes of the inner and outer shoji screens 6 and 7 are maintained. It is possible to delay the communication between the frame and the shoji by the heat expansion material over the four circumferences of the fitting.

As described above, in the fire-prevention fittings of the other embodiments of the present invention, a reinforcing core material or a reinforcing member made of a metal material is arranged together with a heat-expanding material on a frame body and a frame body formed of a resin material. , It is possible to construct fittings specialized for fire prevention performance.
Since the frame of the fire-prevention fitting is formed as a frame having a simple shape in which the rail member is arranged on the inner peripheral surface of the plate-shaped member, the room of the fitting that does not have the conventional fire-prevention performance (outdoor). The frame can be installed inside the building opening by using a fixing means such as a screw, and high fire prevention performance can be easily given to the building opening.
Then, by combining the fireproof fitting with a fitting that guarantees watertightness, airtightness, and wind pressure resistance at the opening of the building to form a double fitting, the watertightness, airtightness, wind pressure resistance, and fire resistance can be improved as a whole. The fittings to be held can be easily and surely constructed.

In the present invention, the outdoor fittings are provided with watertightness, airtightness and wind pressure resistance as well as fireproof performance, and similarly, the indoor fittings are provided with watertightness in addition to fireproof performance. It does not exclude those having airtightness and wind pressure resistance, but at least the outdoor fittings ensure the watertightness, airtightness and wind pressure resistance at the building opening, and the indoor fittings are fireproof at the building opening. Anything that guarantees performance will do.
Further, the configuration for imparting watertightness, airtightness and wind pressure resistance to the outdoor fittings is not limited to the configuration of the above embodiment, and similarly, the configuration for imparting fireproof performance to the indoor fittings.
