In this embodiment, when the resin frame portions 11B, 12B, and 13B are molded by two-color molding, all the portions including the tight portions 11e, 12e, and 13e are integrally molded at the same time.

  Thermally expandable members 30 are mounted in the tight material mounting grooves 11d, 12d, and 13d of the resin frame portions 11B, 12B, and 13B, respectively. The thermally expandable member 30 is a non-flammable or flame retardant member that expands due to heat, and for example, a foam material containing thermally expandable graphite can be applied. In the present embodiment, the thermally expandable member 30 formed into a plate shape is applied. That is, the thermally expandable member 30 has a plate shape, and one edge portion is bent at a substantially right angle, and the bent edge portion (attachment edge portion) of the substrate portion 31 protrudes toward both sides. Two engaging protrusions 32 are provided. The thermally expandable member 30 is configured by mounting the engaging protrusion 32 in the tight material mounting grooves 11d, 12d, and 13d of the resin frame portions 11B, 12B, and 13B in a state where the base plate portion 31 extends toward the outer periphery.

The intermediate portion 30a of the thermally expandable member 30 is located in any of the frame materials 11, 12, 13 and the frame materials 22, 23, 24 in the space between the frame materials 11, 12, 13 and the frame materials 22, 23, 24. Are not in contact with each other, and are far away from the frame members 11, 12, 13 and the frame members 22, 23, 24.

  In the joinery configured as described above, since the frame members 11, 12, and 13 having the resin frame portions 11B, 12B, and 13B are applied, the (a) in FIG. 3 and the (a) in FIG. And as shown to (a) of FIG. 5, since the heat insulation air layer 40 will be comprised between the thermally expansible member 30 and the frame materials 11, 12, 13, it is heat insulation with respect to a prospective direction. This is advantageous. Moreover, the thermally expandable member 30 is provided with the engaging protrusion 32 only on one edge, and the intermediate portion 30a is separated from both the frame members 11, 12, 13 and the flange members 22, 23, 24. Therefore, even if water such as condensed water or rainwater adheres to the frame members 11, 12, 13 and the brazing materials 22, 23, 24, it is possible to suppress the situation in which the influence affects the thermally expandable member 30. Can do.

  Furthermore, the edge part in which the engagement protrusion part 32 was provided in the thermally expansible member 30 is the finding surface 11Ca, 12Ca, 13Ca which faces the outdoor side of the shoji receiving part 11C, 12C, 13C provided in the frame materials 11, 12, 13 And a space between the finding surfaces 22a, 23a, 24a facing the interior of the brazing materials 22, 23, 24. Therefore, at the time of fire occurrence, the thermally expandable member 30 is in the initial stage of thermal expansion as shown by the cross-hatched portion 30 ′ in FIGS. 3B, 4 B and 5 B. In this stage, the gaps between the finding surfaces 11Ca, 12Ca, 13Ca of the frame members 11, 12, 13 and the finding surfaces 22a, 23a, 24a of the saddle members 22, 23, 24 are surely closed. As a result, according to this joinery, it is possible to prevent a situation where a flame penetrates into the room at an early stage when a fire occurs, and it is possible to improve fire resistance.

  In addition, in embodiment mentioned above, although the vertical sliding window is illustrated as joinery, if the shoji 20 is arrange | positioned with respect to the frame 10, of course, it can apply also to other joinery. Is possible. Furthermore, although what has metal frame part 11A, 12A, 13A and resin frame part 11B, 12B, 13B is illustrated as frame material 11,12,13, this invention is not limited to this, A metal frame The present invention can also be applied to a joinery having a frame material made up of only parts.

  In the above-described embodiment, the engagement protrusion 32 is provided only on one edge of the thermally expandable member 30, so that the attachment work to the frame members 11, 12, and 13 is facilitated. However, engagement protrusions may be provided at both ends. Note that the engagement protrusion 32 is provided only on one edge of the thermally expandable member 30, and the frame members 11, 12, and 13 have the metal frame portions 11A, 12A, and 13A and the resin frame portions 11B, 12B, and 13B. In the embodiment described above, the tight material mounting groove portions 11d, 12d, and 13d are provided in the resin frame portions 11B, 12B, and 13B in the above-described embodiment, but the present invention is not limited to this.

  For example, in the first modification shown in FIG. 6, a tight material mounting groove 11g is provided on the prospective surface 11h on the inner peripheral side of the frame 10 in the metal frame portion 11A of the upper frame material 11, and the tight material mounting groove 11g is heated. The engagement protrusion 132 of the inflatable member 130 is attached. The other edge of the thermally expandable member 130 is engaged with an engaging portion 11j provided on the resin frame portion 11B. As is apparent from the drawing, the substrate 131 of the thermally expandable member 130 of Modification 1 has a simple flat plate shape and does not have a bent portion. Also in this modified example 1, it goes without saying that the intermediate portion 130 a of the thermally expandable member 130 is disposed so as to be separated from both the upper frame member 11 and the upper flange member 22. Further, the tight material mounting groove 11d formed in the resin frame portion 11B has a tight material 114 molded separately from the upper collar material 22 so as to come into contact with the finding surface 22a facing the interior of the upper collar material 22. You just have to wear. In FIG. 6, only the upper frame member 11 is described, but the lower frame member 12 and the left and right vertical frame members 13 can be similarly configured. Moreover, the same code | symbol is attached | subjected about the structure similar to embodiment in the modification 1. FIG.

  Also in the fitting of this modification 1, since the upper frame member 11 having the resin frame portion 11B is applied, the heat insulating air layer 40 is configured between the thermally expandable member 130 and the upper frame member 11. Therefore, it is advantageous in terms of heat insulation with respect to the prospective direction. In addition, the thermally expandable member 130 is provided with the engaging protrusion 132 only on one edge, and the intermediate portion 130a is disposed so as to be separated from both the upper frame member 11 and the upper flange member 22. Even if water such as dew condensation water or rainwater adheres to the upper frame member 11 or the upper frame member 22, it is possible to suppress a situation in which the influence reaches the thermally expandable member 130. Further, one edge portion of the thermally expandable member 130 is interposed in a gap between the finding surface 11Ca facing the outdoor side of the shoji receiving portion 11C provided on the upper frame member 11 and the finding surface 22a facing the interior of the upper collar member 22. It becomes a state. For this reason, in the event of a fire, the thermally expandable member 130 reliably closes the gap between the finding surface 11Ca of the upper frame member 11 and the finding surface 22a of the upper collar member 22 in the initial stage of thermal expansion. As a result, according to this joinery, it is possible to prevent a situation where a flame penetrates into the room at an early stage when a fire occurs, and it is possible to improve fire resistance.

  Further, in the second modification shown in FIG. 7, the metal frame portion 13A of the vertical frame member 13 is provided with a tight material mounting groove 13k, and the engagement protrusion 232 of the thermally expandable member 230 is mounted in the tight material mounting groove 13k. I am doing so. The other edge (hereinafter referred to as a free edge) of the thermally expandable member 230 is disposed close to the engaging portion 13m provided in the metal frame portion 13A, but is not in contact with the metal frame portion 13A. It is in the state of. When the free edge portion of the thermally expandable member 230 moves in a direction away from the metal frame portion 13A, the free edge portion engages with the engaging portion 13m, and subsequent movement is prevented. As in the first embodiment, in the thermally expandable member 230 according to the second modification, one edge portion where the engagement protrusion 232 is provided in the substrate portion 231 is bent. Also in this modified example 2, it goes without saying that the intermediate portion 230 a of the thermally expandable member 230 is disposed so as to be separated from both the vertical frame member 13 and the vertical rod member 24. In addition, the tight material mounting groove 13d formed in the resin frame portion 13B has a tight material 214 formed separately from the vertical saddle member 24 so as to come into contact with the finding surface 24a facing the interior of the vertical saddle member 24. You just have to wear. In FIG. 7, only the vertical frame member 13 is described, but the upper frame member 11 and the lower frame member 12 can be similarly configured. In the second modification, the same reference numerals are assigned to the same configurations as those in the embodiment.

  Also in the fitting of this modified example 2, since the vertical frame member 13 having the resin frame portion 13B is applied, it is advantageous in terms of heat insulation with respect to the prospective direction. In addition, with respect to the thermally expandable member 230, the engaging protrusion 232 is provided only on one edge, and the intermediate portion 230a and the other free edge are separated from both the vertical frame member 13 and the vertical rod member 24. Therefore, even when water such as condensed water or rainwater adheres to the vertical frame member 13 or the vertical rod member 24, it is possible to suppress a situation in which the influence of the water on the thermally expandable member 230 is affected.

  In the embodiment and the two modifications described above, the shoji is arranged to be openable and closable with respect to the frame body. However, the shoji does not necessarily need to be opened and closed. It is also possible to apply it to an incision window fixed to.
