  In the case of the single sliding door sash described above, when the downside resin member melts and falls off due to combustion during a fire, the upper wall (or lower Ii) will be supported. Therefore, there is a problem that the load acting on the joint portion between the vertical gutter and the upper gutter (or the lower gutter) becomes large, and sufficient rigidity of the shoji cannot be secured.

  Then, this invention is made | formed in view of the said situation, and provides the sliding door which can join firewood firmly and can ensure fireproof performance.

In order to achieve the above object, the present invention employs the following means.
That is, the sliding door according to the present invention is provided with a frame provided at the opening of the structure, a vertical slid provided in the frame so as to be slidable in the finding direction, and extending in the vertical direction, and joined to the vertical fold. A shoji having a recumbent extending in the direction of finding, wherein the downspout is formed of a metal downspout portion formed of metal and a resin provided on the indoor side in the prospective direction of the downspout portion of the metal. And the recumbent portion has a metal recumbent portion formed of metal, and has a reinforcing surface disposed along the indoor side of the metal recumbent portion. The reinforcing metal fittings are fixed to the metal vertical flanges and formed of metal.

  In the sliding door constructed as described above, when the downside of the downside of the downspout is melted due to a fire, it is fixed to the downside of the downspout and downside of the downside of the downside of the metal. The load of the reed can be supported by the reinforcing metal fitting having the reinforcing surface arranged in the manner described above. Therefore, the heels can be firmly joined to each other by the reinforcing metal fitting provided at the joint portion where the vertical heel and the horizontal heel are joined. Therefore, since the rigidity of a sliding door can be ensured, deformation | transformation of a sliding door can be suppressed and fire prevention performance can be ensured. Moreover, generation | occurrence | production of the clearance gap in a junction part can be suppressed and fire prevention performance can be ensured.

  Further, in the sliding door according to the present invention, the recumbent has a resin reed part formed of resin provided on the indoor side of the metal reed part, and the resin reed part is formed of the metal reed part. An outdoor resin part disposed on the indoor side of the part, and an indoor resin part disposed on the indoor side spaced apart from the outdoor resin part in the prospective direction. It arrange | positions in the space part formed between the outdoor side resin part and the said indoor side resin part.

  In the sliding door configured as described above, the reinforcing surface of the reinforcing metal fitting is disposed in the space formed between the outdoor resin portion of the resin lateral flange portion and the indoor resin portion, so that the reinforcing surface is exposed. The fireproof performance can be secured by firmly joining the heels while suppressing the fire.

  Moreover, the sliding door which concerns on this invention is provided with the heating foam material which can be foamed by heating in the said outdoor side of the said reinforcement surface.

In the sliding door configured as described above, the heat foaming material provided on the outdoor side of the reinforcing surface of the reinforcing bracket foams due to the heat of the fire, so that there is a gap in the joint portion between the vertical and horizontal members. It is blocked. Therefore, it is possible to suppress the inflow of combustible gas generated by melting the members such as the vertical gutter and the horizontal gutter due to the heat of the fire into the indoor side.
Further, when the reinforcing surface of the reinforcing metal fitting is disposed in the space formed between the outdoor resin portion and the indoor resin portion of the resin lateral flange portion, the heated foam material is surely disposed in the entire space portion. Can be foamed.

  According to the sliding door according to the present invention, fireproof performance can be secured by firmly joining the ridges.
