  In the sliding window 100 according to the present embodiment, when a fire occurs, each heating foam material foams. Specifically, the heat-foamable material F1 is foamed in the indoor and outdoor directions to close the gap between the outdoor side wall portion 61 of the door tip 23 and the bottom surface portion 141 of the core material 140. The heating foam material F2 is foamed indoors to close the hollow portion S11 of the bowl 23 of the door tip. The heat-foaming material F3 is foamed to the outside side to close the hollow portion S12 of the door tip 23.

  Moreover, the heating foam material F4 foams on the side separated from the facing vertical frame 13. The outer prospective weir wall portion 63 is melted, and the portion of the foamed heating foam material F4 on the side away from the facing vertical frame 13 abuts on the side surface portion 142 of the weir core material 140. Since the core material 140 is connected to the core material 140 of the upper rod 21 and the core material 140 of the lower core 22 and has a square frame shape as a whole and has high rigidity, the core material 140 itself is unlikely to be deformed or displaced. Therefore, the heating foam material F4 can not foam any more on the side away from the opposing vertical frame 13. In this state, the foaming force in the left-right direction of the heating foam material F4 deforms the thin core material 150 (of a thin plate) whose strength is lower than that of the core material 140 toward the facing vertical frame 13 side. Specifically, since the winding core 150 is fixed to the side surface portion 142 of the winding core 140 by screws 156 near the upper and lower end portions, the winding core 150 is opposed to the opposing vertical frame 13 at the center in the vertical direction. While it swells largely (displaces to the opposing vertical frame 13 side), it does not swell so much at the upper and lower end parts (does not displace to the opposing vertical frame 13 side).

FIG. 7 is a part of an enlarged view of a portion C in FIG. 3 and shows a state in which the heating foams F4, F5 and F6 are foamed at the time of a fire. In FIG. 7, the resin members of the vertical frame 13 and the door 23 are illustrated as not being melted.
In the normal state, the end on the side of the facing vertical frame 13 in the side portions 152 and 153 of the core 150 and the end of the inner projecting piece 133 of the projecting portion attachment 130 of the vertical frame 13 are along the indoor and outdoor directions. Since it is on the same plane, as shown in FIG. 7, when the firewood shifts to the facing vertical frame 13 side at the time of fire, the end of the facing vertical frame 13 side in the side portions 152 and 153 of the windscreen 150 The portions 152a and 153a and the protrusion attachment 130 overlap in the indoor and outdoor direction.

  Furthermore, the foam of the heating foam material F4 suppresses the transfer of the heat of the flame to the bottom surface portion 151 of the metal core material 150.

  In addition, the heating foam material F5 is foamed on the side of the facing vertical frame 13 to close the engagement groove G3 of the door tip 23. As shown in FIG. 7, the heating foam material F5 foams until it protrudes from the engagement groove G3.

  Further, the heat-foamable material F6 is foamed indoors to close the gap between the first outdoor side wall portion 71 of the door tip 23 and the side surface portion 152 of the core material 150. The foamed heated foam material F6 may be integrated with the heated heated foam material F4 (see FIG. 7). Furthermore, the foam of the heating foam material F6 suppresses the transfer of the heat of the flame to the side surface portion 152 of the metal core material 150.

  Further, at the upper and lower end portions of the end portions on the opposing vertical frame 13 side of the shoji 2, the corner connecting portion 163 of the corner member 160 is pushed toward the opposing vertical frame 13 by the foamed heating foam material F4. When the resin member of the door tip collar 23 is melted and the outdoor side step wall portion 72, the second outdoor side wall portion 73, the first indoor side wall portion 74 and the indoor side step wall portion 75 are deformed, a corner The inclined piece portions 161c and 162c of the member 160 are formed at the corner formed by the outdoor side step wall portion 72 and the second outdoor side wall portion 73, and the indoor side step wall portion 75 and the second indoor side wall, respectively. It climbs over the corner formed by the wall 76. Then, the corner member 160 is displaced to the opposing vertical frame 13 side. And the edge part 152a, 153a by the side of the vertical frame 13 which opposes in the corner finding surface part 161,162 of the corner member 160 and the protrusion attachment 130 overlap in the indoor outside direction.

  At the time of a fire, the heating foam material F6 foams in the indoor side by the sliding window 100 comprised in this way. Since the side part 152 of the coffin core material 150 is disposed indoors more than the heating foam material F6, the heat of the flame is transferred to the indoor side at the time of fire on the outdoor side by the foamed heating foam material F6, Transmission to the side surface portion 152 of the material 150 is suppressed. Therefore, the temperature of the side surface portion 152 is transmitted to the first outdoor side side wall portion 71 of the engagement groove G3 opposed to the side surface portion 152, and melting of the first outdoor side side wall portion 71 is suppressed. Therefore, it is suppressed that the side part 152 of the coffin core material 150 and the 1st outdoor side cocoon wall part 71 of a door tip are high temperature, and it can have a high fire prevention performance.

In the event of a fire, the heating foam material F4 foams on the side away from the facing vertical frame 13.
Since the bottom portion 151 of the core material 150 is disposed on the side of the vertical frame 13 opposed to the heating foam F4, the heat of the flame is moved to the side of the vertical frame 13 opposed by the foamed heating foam F4. Transmission to the bottom surface portion 151 of the batting material 150 is suppressed. Therefore, it can be suppressed that the bottom surface portion 151 of the core material 150 becomes high temperature, and high fire performance can be provided.

  Furthermore, in the engagement groove G3 of the resin-made door tip collar 23, between the prospective outer wall portion 63 (the bottom portion of the engagement groove G3) and the bottom surface portion 151 of the core material 150 disposed along the indoor and outdoor directions. The heating foam material F4 is arrange | positioned in-between | in-the-meantime. Therefore, since it is suppressed that the outside prospective collar wall part 63 of the door tip collar 23 contacts directly with the bottom face part 151 of the metal core material 150, the outer prospective collar wall of the engagement groove G3 of the door tip collar 23 It is suppressed that the part 63 becomes high temperature.

  Further, on the side of the engaging groove G3 which is separated from the facing vertical frame 13, there is formed a recess G4 which is in communication with the engaging groove G3 and which is recessed on the outdoor side and the indoor side. Since the heating foam material F6 is accommodated in the recess G4, the heating foam material F6 does not interfere with the attachment of the core material 150.

  The shapes, combinations, and the like of the constituent members shown in the above-described embodiment are merely examples, and various changes can be made based on design requirements and the like without departing from the spirit of the present invention.

  For example, a heating foam may be provided on the outdoor side (opposite to the heating foam F6 side) of the first outdoor side wall portion 71 of the door tip collar 23 so that the first outdoor side wall portion 71 becomes hot. May be suppressed.

  Moreover, in the embodiment shown above, although the frame 1 and the housing 20 are resin, in the housing 20 which is not limited to this, at least the engagement groove G3 of the door tip 23 The wall 63, the first outdoor side wall 71, the outdoor side wall 72, the second outdoor side wall 73, the first indoor side wall 74, the indoor side wall 75 and a second store The inner wall portion 76) may be made of a resin member. For example, a metal member such as aluminum may be provided on the surface on the most outdoor side or the surface on the most indoor side of the housing 20.

  Moreover, in embodiment shown above, although the heating foam material F6 is arrange | positioned in the recessed part G3 formed in communication with the engaging groove G3, this invention is not limited to this. A heating foam may be disposed in the recess G4. In this case, the heat-foamable material provided in the recess G4 does not interfere with the attachment of the core material 150. Moreover, it is suppressed that the heat | fever of a flame moves to the outdoor side at the time of the fire by the side of indoors, and is transmitted to the side part 153 of the core material 150 by the foamed heating foam material. Therefore, the temperature of the side surface portion 153 is transmitted to the first indoor side inner wall wall portion 74 of the engagement groove G3 facing the side surface portion 153, and the melting of the first indoor side inner wall wall portion 74 is suppressed. Therefore, it can be suppressed that the side part 153 of the coffin core material 150 and the first indoor side cocoon wall part 74 of the front door are high temperature, and high fire performance can be provided. Furthermore, the recesses G4 and G5 may not be formed in the engagement groove G3, and the heating foam may be disposed in at least one of the outdoor side and the indoor side of the core material 150 in the engagement groove G3. .
