Description

  The present invention relates to a sash in which a shoji is movably accommodated in a frame provided in an opening of a building, and more particularly to a sash that is not ignited even when a door wheel that allows the shoji to run is melted in the event of a fire.

  Examples of the sash in which the internal and external shojis are housed in the frame provided in the opening of the building include a sliding sash that allows the internal and external shojis to run in a sliding manner, and a single-drawing sash that allows one of the shojis to run. In either case, a resin door is provided on the lower side of the traveling shoji. Since the door roller needs strength that supports the weight of the shoji, elasticity that can rotate smoothly, and wear resistance, a resin material such as polyacetal is used as the material.

  On the other hand, a heating foam material is provided at the lower end portion of the lower heel in order to close the gap between the lower frame and the lower heel in the event of a fire to increase the fireproof performance. The heated foam material foams and increases in volume when it reaches a predetermined temperature or higher, thereby closing the space between the lower frame and the lower heel. As such a sash in which the heating foam is provided on the lower arm as described above, for example, there is one described in Patent Document 1.

FIG. 3 shows an enlarged longitudinal sectional view of the vicinity of the lower frame 11 and the lower eyelid 21 on the side where the external shoji 3 is arranged. An outdoor airtight material holding wall 11b extending toward the outdoor side is formed on the rail portion 11a for guiding the inner frame 2 of the lower frame 11, and an airtight material 11c is provided along the longitudinal direction at the distal end of the rail portion 11a. The shoji 3 comes into contact with the inner surface of the lower arm 21 of the shoji 3.

  The door wheel 24 a is made of polyacetal, which is a resin material, and is held by a metal door wheel member 24. The lower arm 21 has an outdoor hanging part 21a with an outdoor side wall hanging down and an indoor hanging part 21b with an indoor side wall hanging down, and a door roller member 24 is located in a region sandwiched between the outdoor hanging part 21a and the indoor hanging part 21b. Is arranged. The outdoor hanging part 21a and the indoor hanging part 21b are respectively opposed to the outdoor side surface and the indoor side surface of the rail portion 11a of the lower frame 11 that guides the shoji 3.

  A lower wall portion 21d is formed at the base portion of the outdoor hanging portion 21a and the indoor hanging portion 21b of the lower rod 21, and the drawing member 25 is fixed to the lower wall portion 21d. . The drawing member 25 hangs downward, and an inclined drawing portion 25 a formed at an intermediate position thereof faces the rail portion 11 a of the lower frame 11.

  A heating foam material 21c is provided on the outdoor hanging portion 21a of the lower rod 21 over substantially the entire length in the longitudinal direction of the surface of the lower frame 11 that faces the rail portion 11a. The heating foam material 21c is held by a concave lower holding portion 21e formed at the lower end portion of the outdoor hanging portion 21a, and the upper holding portion 25b having an upper end hanging from the outdoor end portion of the pulling member 25; It is held by the upper holding portion 24 b that is the outdoor lower end portion of the door pulley member 24. Since the door wheel member 24 is provided at both left and right ends of the lower arm 21 and a plurality of the pulling members 25 are provided at the intermediate portion between the door wheel members 24, the upper holding portion 24b of the door wheel member 24 and the pulling member 25 The heated foam material 21c is held by both the upper holding portions 25b. Thereby, the heating foam material 21c to be arranged in the vertical direction can be fixed without using an adhesive tape, and can be prevented from falling off due to deterioration over time.

  The upper end position of the rail part 11a of the lower frame 11 will be arrange | positioned in the projection surface in the indoor / outdoor direction of the heating foam material 21c. That is, the heating foam material 21c is provided so as to straddle the upper end position of the rail portion 11a in the vertical direction, and the upper portion of the heating foam material 21c faces the outdoor side surface of the door wheel 24a. Since the upper end position of the rail portion 11a is the lower end position of the door wheel 24a, the lower end position of the heating foam material 21c is lower than the lower end position of the door wheel 24a. When the heating foam material 21c is foamed, it expands in the direction in which the heating foam material 21c faces. Therefore, when the sash is exposed to a high temperature in the event of a fire, the heating foam material 21c moves the door wheel 24a from the outdoor side surface to the room. It will press toward the inside.

  FIG. 4 shows an enlarged vertical cross-sectional view of the vicinity of the lower frame 11 and the lower rod 21 on the side where the external shoji 3 is arranged in the state at the time of the occurrence of a fire. When a fire occurs and the sash is exposed to a high temperature, the resin door roller 24a softens and melts, and the lower arm 21 that has lost the door wheel 24a has an outdoor hanging portion 21a and an indoor hanging portion 21b on the inner peripheral surface of the lower frame 11. Move down until hitting. The lower end positions of the outdoor hanging part 21a and the indoor hanging part 21b are substantially the same position in the vertical direction, and the inner peripheral surface of the lower frame 11 is formed in an inclined surface shape in which the indoor side is higher than the outdoor side. The hanging portion 21 b contacts the inner peripheral surface of the lower frame 11. If the inner peripheral surface of the lower frame 11 has the same height in the indoor / outdoor direction, both the outdoor hanging portion 21a and the indoor hanging portion 21b come into contact with the inner peripheral surface of the lower frame 11. When the lower rod 21 moves downward, the drawing portion 25a of the drawing member 25 comes into contact with the upper end of the rail portion 11a of the lower frame 11. Since the attracting portion 25a has an inclined surface shape from the outside to the indoor side from the top to the bottom, by contacting the rail portion 11a, the lower rod 21 is drawn toward the indoor side, and the lower portion of the airtight material 11c 21 is maintained so as not to generate a gap.

  The polyacetal composing the door wheel 24a melts at 165 to 181 ° C. On the other hand, the heated foam material 21c foams when the temperature is about 200 ° C. or higher. The heating foam material 21c is in contact with the lower arm 21 made of aluminum material on the entire surface, whereas the door wheel 24a is in contact with the lower frame 11 made of aluminum material at the lower end, and the metal door wheel member 24 at the shaft part. Since it is only in contact, the temperature of the heating foam material 21c is likely to rise, and the door wheel 24a rises with a delay later than the heating foam material 21c. For this reason, when an actual fire occurs, the time when the door wheel 24a starts to melt and the time when the heated foam material 21c starts to foam are substantially the same. Thereby, the heating foam material 21c presses the door wheel 24a which has started to melt toward the indoor side.

  Since the outdoor hanging part 21a and the outdoor hanging part 21b of the lower rod 21 are connected by the lower wall part 21d, even if the heating foam material 21c is on the non-heated surface side, heat is easily transmitted and the door wheel 24a is melted. Before the heating foam material 21c can be foamed.

  As shown in FIG. 4, the door wheel 24a pressed to the indoor side by the heating foam material 21c is melted to become a resin material 24c, and between the rail portion 11a of the lower frame 11 and the indoor hanging portion 21b of the lower rod 21. It will be in a staying state. Moreover, the clearance gap between the internal peripheral surface of the lower frame 11 and the lower collar 21 will be in the state obstruct | occluded along the longitudinal direction with the heating foam material 21c. Accordingly, the molten resin is not infiltrated into the heating foam material 21c that closes the gap by pushing the molten door pulley 24a toward the indoor side of the rail portion 11a while closing the gap between the lower frame 11 and the lower rod 21. In addition, it is possible to prevent the molten resin from flowing out to the indoor side of the lower casing 21, and it is possible to prevent the door wheel 24a from being ignited by the molten resin even in the event of a fire.

  Even if the melted resin flows out to the indoor side from the indoor hanging part 21b of the lower lid 21, the outdoor airtight material holding wall 11b formed on the lower frame 11 is separated from the indoor side space from the indoor hanging part 21b. Further, it is separated from the indoor space and is kept airtight by the airtight material 11c. Thereby, in the state where the indoor hanging part 21b is in contact with the inner peripheral surface of the lower frame 11, the space closed by the inner periphery of the lower collar 21 and the lower frame 11, the outdoor airtight material holding wall 11b, and the airtight material 11c. Therefore, it is possible to prevent the combustible gas generated from the molten resin from entering the indoor side. In addition, a part of the indoor hanging part 21b of the lower rod 21 with which the airtight material 11c abuts is formed in a protruding shape toward the indoor side so as to surely contact the airtight material 11c before and after the occurrence of the fire. ing.

The Rukoto. That is, the heating foam material 21c is provided so as to straddle the upper end position of the rail portion 11a in the vertical direction, and the upper portion of the heating foam material 21c faces the outdoor side surface of the door wheel 24a. Since the upper end position of the rail portion 11a is the lower end position of the door wheel 24a, the lower end position of the heating foam material 21c is lower than the lower end position of the door wheel 24a. When the heating foam material 21c is foamed, the door wheel 24a can be pressed toward the indoor side of the rail portion 11a.

  FIG. 6 shows an enlarged vertical cross-sectional view of the lower frame 11 and the vicinity of the lower eyelid on the side on which the inner shoji 2 is arranged in the state at the time of the occurrence of the fire. When a fire occurs, the inner shovel 2 also moves downward until the indoor hanging part 21b hits the inner peripheral surface of the lower frame 11 by melting the door wheel 24a. At this time, the heated foaming material 21c presses the door wheel 24a that has started to be melted against the indoor side of the rail portion 11a, and the molten resin material stays in the space between the rail portion 11a and the indoor hanging portion 21b. Become. Moreover, the clearance gap between the internal peripheral surface of the lower frame 11 and the lower collar 21 will be in the state obstruct | occluded along the longitudinal direction with the heating foam material 21c.

  Thereby, the effect similar to the external shoji 3 can be acquired also in the internal shoji 2. Further, even if the resin flows out from the indoor hanging portion 21b to the indoor side, it is generated from the molten resin because the indoor airtight material holding wall 11d formed in the lower frame 11 blocks the indoor space. It is possible to prevent combustible gas from entering the indoor side.

  On the other hand, the first hermetic portion 28 b is shorter than the second hermetic portion 28 c, and the distal end portion is close to the indoor side surface of the external obstacle 3. When the outer shoji 3 is pressed indoors by a strong wind or the like, the first airtight portion 28b abuts against the indoor side surface of the outer shroud 3, and the vertical airtight portion 27c and the lower airtight portion 27d of the lower anti-vibration component 27 The hermeticity between the summoning bowls 23 can be increased by continuing the hermetic line. Moreover, since only the 2nd airtight part 28c is normally contact | abutting to the outer shoji 3 at the time of normal, the opening / closing operation of the inner shoji 2 and the outer shoji 3 can be lightened.

  Although the embodiment of the present invention has been described above, the application of the present invention is not limited to this embodiment, and can be applied in various ways within the scope of its technical idea.
