On the inner peripheral side of the lower collar 21, a concave panel body holding groove 21 b for accommodating the lower edge of the panel body 4 is formed. On the inner peripheral side of the vertical rod 22, a concave panel body holding groove 22 b that houses the peripheral edge of the vertical side of the panel body 4 is formed.

  The configuration in the panel body holding groove will be described in detail. FIG. 3 shows an enlarged view of the vicinity of the lower eyelid 21 in FIG. The lower edge of the panel body 4 is inserted from the opening 21c of the panel body holding groove 21b to the far side, and the three surfaces of the panel body 4 including the indoor side surface 4a, the outdoor side surface 4b, and the end surface 4c are within the panel body holding groove 21b. Is exposed.

  The glass plate constituting the panel body 4 is a multilayer glass formed by integrating two single-sheet glass indoors and outdoors with a seal portion 4d. The seal portion 4d is made of a silicon-based material. The lower side of the panel body 4 is placed on a setting block 21h disposed on the bottom wall of the panel body holding groove 21b. The setting block 21h is short in the longitudinal direction of the lower collar 21, and is provided at a plurality of locations.

  A sealing material 21e is provided between the panel body 4 and the opening 21c of the panel body holding groove 21b. Further, a receiving member 21f that receives the sealing material 21e is provided on the back side of the sealing material 21e of the panel body holding groove 21b. The receiving member 21f is made of, for example, a ceramic incombustible material having a circular or square cross section, and is provided along the longitudinal direction of the lower collar 21, so that when the sealing material 21e is provided, the sealing material 21e is a panel. The body holding groove 21b is prevented from entering.

  A support piece 21d that supports the receiving member 21f from below is formed in the panel body holding groove 21b. The support piece 21d prevents the receiving member 21f from entering the back side of the panel body holding groove 21b. The panel body 4 is inserted further into the panel body holding groove 21b than the sealing material 21e and the receiving member 21f, so that the indoor side surface 4a, the outdoor side surface 4b, and the end surface 4c are connected to the panel body holding groove as described above. It is exposed in 21b.

  A heating foam material 21g is arranged on the bottom wall constituting the inner wall surface of the panel body holding groove 21b. The heated foam material 21g is in the form of a sheet, foams in the plane direction at about 200 ° C., and increases in volume by several tens of times. The heating foam material 21g is provided along the longitudinal direction of the panel body holding groove 21b. For example, the heating foam material 21g may be placed on the bottom wall in addition to being fixed to the bottom wall with a double-sided tape. Further, a drain hole 21k for draining the infiltrated water is formed in the bottom wall of the panel body holding groove 21b.

  When a fire occurs and the sash is exposed to a high temperature, the sealing material 21e that holds the panel body 4 contracts at about 400 to 500 ° C., peels off from the panel body holding groove 21b, and falls off due to its own weight. 4 and the frame body 1, and the support of the panel body 4 is lost as it is. However, instead of this, the heated foaming material 21 g is foamed and the volume is increased. Maintain support. The same applies when the sealing material 21e is melted. FIG. 4 shows an enlarged longitudinal sectional view of the vicinity of the lower armpit 21 in the state at the time of the fire.

  As shown in FIG. 4, the seal material 21e is lost when a fire occurs. At this time, the heating foam material 21g foams so as to fill the inside of the panel body holding groove 21b. For this reason, the panel body 4 in which the indoor side surface 4a, the outdoor side surface 4b, and the end surface 4c are exposed in the panel body holding groove 21b is in a state where these three surfaces are held by the heating foam material 21g. Thereby, since the support state of the panel body 4 is maintained, it can prevent that a clearance gap produces between the panel body 4 and the panel body holding groove 21b. Although the shoji 2 is comprised by the housing 3 and the panel body 4, according to the structure by the housing 3 side, fireproof performance can be ensured reliably irrespective of the construction state of the panel body 4. FIG.

  When the fire is generated, the heated foam material 21g fills the inside of the panel body holding groove 21b, so that the drain hole 21 of the panel body holding groove 21b can be closed. It is possible to prevent the outside from communicating. Moreover, generation | occurrence | production of combustible gases, such as a silicon type combustible gas generated from the secondary seal of a glass edge, and EPDM * PVC generated from a setting block, can be prevented.

  According to this configuration, damage to the panel body 4 can also be prevented. The glass plate which comprises the panel body 4 may be cracked when a local temperature difference arises. The seal portion 4d constituting the panel body 4 is made of a silicon-based material as described above, and generates flammable gas when exposed to a high temperature. There is a risk of getting inside.

  As shown in FIG. 1, when the sash is exposed to a high temperature from the outdoor side, the temperature of the portion of the panel body 4 exposed from the opening 21c to the outside of the panel body holding groove 21b greatly increases. On the other hand, the portion of the panel body 4 exposed in the panel body holding groove 21b is surrounded by the lower collar 21 made of a metal material, so that the temperature rise is small and the portion exposed to the outside of the panel body holding groove 21b. And the temperature difference becomes large. However, since the heat foaming material 21g foams and fills the inside of the panel body holding groove 21b, the heat from the lower flange 21 is transferred to the edge of the panel body 4 through the heating foam material 21g, so the temperature difference is reduced. can do. Thereby, damage to the panel body 4 can be prevented. The same applies to the case where the sash is exposed to a high temperature from the indoor side, contrary to FIG.

  Moreover, the panel body 4 is a multi-layer glass, and the outdoor side panel body and indoor side panel body which consist of a glass plate are arrange | positioned facing both indoors and outdoors via the secondary sealing material. Assuming heating from the outdoor side, the outdoor panel body serving as the heating surface is a glass with high heat resistance, and the indoor panel body serving as the non-heating surface is a low radiation glass having a reflective film, In addition to being heated, the outdoor panel body is likely to have a higher temperature due to reflection from the low radiation glass on the non-heated surface side.

  At this time, although the meshed glass is cracked, it does not collapse because it has a mesh. Therefore, if the secondary sealing material between the outdoor panel body and the indoor panel body peels off due to high temperature, the restraint of both And the center part of the outdoor panel body is greatly deformed in the surface direction, so that the flange member is largely deformed and the panel body 4 cannot be supported. On the other hand, when the heating foam material 21g is foamed, the supporting state of the panel body 4 can be maintained and the gap generated between the flange member and the panel body 4 can be closed. Even when the heating surface side is also low emission glass, the low emission glass on the heating surface side only cracks and does not collapse. It is possible to support the body 4 and close the gap.

  The upper collar 20 is configured in the same manner as the lower collar 21. As shown in FIG. 1, the peripheral side of the upper side of the panel body 4 has the indoor side surface 4 a, the outdoor side surface 4 b, and the end surface 4 c exposed in the panel body holding groove 20 b of the upper collar 20. A sealing member 20d and a receiving member 20e are provided between the grooves 20b, and a support piece 20c is formed on the back side of the receiving member 20e.

  A pocket-shaped holding portion 20f is formed on the side wall constituting the inner wall surface of the panel body holding groove 20b, and the heating foam 20g is held and fixed by the holding portion 20f and the support piece 20c. The heating foam material 20g can fill the inside of the panel body holding groove 20b in the event of a fire, like the heating foam material 21g of the lower lid 21. With this configuration, when a fire occurs, the peripheral edge exposed in the panel body holding groove 20b of the panel body 4 can be held by the heated foam material 20g, and the same effect as described above can be obtained.

  The vertical gutter 22 is configured in the same manner as the lower gutter 21. As shown in FIG. 2, the peripheral edge of the vertical side of the panel body 4 has the indoor side surface 4 a, the outdoor side surface 4 b, and the end surface 4 c exposed in the panel body holding groove 22 b of the vertical rod 22. A sealing material 22d and a receiving member 22e are provided between the holding grooves 22b, and a support piece 22c is formed on the back side of the receiving member 22e.

  For example, a heating foam 22f is fixed to the bottom wall constituting the inner wall surface of the panel body holding groove 22b with screws or rivets. The heating foam material 22f can fill the inside of the panel body holding groove 22b in the event of a fire, like the heating foam material 21g of the lower casing 21. With this configuration, when a fire occurs, the heating foam 22f expands in the surface direction toward the peripheral edge of the panel body 4 to form a concave shape, and holds the peripheral edge exposed in the panel body holding groove 22b of the panel body 4. The same effect as described above can be obtained.

  In the upper punch 20, the heating foam 20g is physically held and fixed by the holding portion 20f, and in the vertical hook 22, the heating foam 22f is physically fixed by screwing. It is not necessary to use a double-sided tape for fixing the heating foams 20g and 22f. In particular, in the case of the upper rod 20 and the vertical rod 22, the heating foams 20g and 22f cannot be maintained without being fixed, but the adhesive strength of the double-sided tape is lowered due to deterioration over time, so the heating foams 20g and 22f can fall. There was sex. On the other hand, since the heating foams 20g and 22f are fixed by physical means other than the adhesive force, the falling can be prevented.
