Inner vertical opposing wall portion 13b facing the side end portion 15a of the layered glass 15, outer vertical facing wall portion 13c facing the side end portion 15a of the multilayered glass 15 on the outdoor side of the multilayered glass 15, and inner longitudinally facing side A vertical bottom portion 13d that is connected to the right edge of the wall portion 13b and the outer vertical opposing wall portion 13c to form the bottom portion of the side glass housing portion 13a, and a hollow portion 13e that penetrates in the longitudinal direction of the vertical rod 13 to the right of the vertical bottom portion 13d. The inner vertical hollow forming wall 13f, the outer vertical hollow forming wall 13g, and the vertical hollow forming bottom 13h are formed together with the vertical bottom 13d. The side glass accommodating portion 13a of the vertical rod 13 has a groove shape opened inward of the casing 10a, and the inner edge portions of the inner vertical opposing wall portion 13b and the outer vertical opposing wall portion 13c protrude to the side facing each other. It has a protruding piece 13i.

  A gasket 17 (FIG. 2) that engages with the protruding piece 13 i of the inner vertical opposing wall portion 13 b and the outer vertical opposing wall portion 13 c is provided in the side glass accommodating portion 13 a of the vertical rod 13. The multi-layer glass 15 is accommodated in the glass housing portions 11 a, 12 a, 13 a, and 14 a of the summon basket 11, the upper rod 12, and the vertical rods 13 and 14 with the peripheral end portion 15 a accommodated in the gasket 17.

  The summon bowl 11 and the vertical bowl 13 are arranged inwardly at the end in the longitudinal direction of the summon bowl 11 so that the lower glass accommodating section 11a of the summit bowl 11 and the side glass accommodating section 13a of the vertical bowl 13 are connected. The opposing wall portion 11b and the outer lower opposing wall portion 11c are cut away. When the summon bowl 11 and the vertical bowl 13 are joined, the lower bottom portion 11d, the inner lower hollow forming wall portion 11f, the outer lower hollow forming wall portion 11g, and the lower hollow forming bottom portion 11h are all included. The hollow portion 11e of the summoning rod 11 is closed by contacting the vertical bottom portion 13d of the vertical rod 13, and the edges in the longitudinal direction of the inner lower facing wall portion 11b and the outer lower facing wall portion 11c of the summing rod 11 are vertical. The flange 13 is brought into contact with a protruding piece 13i provided on the inner vertical opposing wall portion 13b and the outer vertical opposing wall portion 13c. In this state, the tapping screw 30 penetrating the vertical rod 13 is screwed into the screw threaded portion 11j of the summing rod 11, and the summing rod 11 and the vertical rod 13 are joined. At this time, the lower reinforcing member 16 is formed to have the same length as or shorter than the inner lower opposing wall portion 11b and the outer lower opposing wall portion 11c.

  The cross section of the downpipe 13 has an L shape so that the outside vertical opposing wall 13c and the vertical bottom part 13d of the downpipe 13 are covered from the outside of the downpipe 13 along the longitudinal direction. A vertical reinforcing member 18 is provided as an iron adjacent reinforcing member. That is, the lower end portion of the vertical reinforcing member 18 overlaps the outer vertical opposing wall portion 13c and the lower reinforcing member 16 of the vertical rod 13 in the prospective direction, and the vertical reinforcing member 18 penetrates the outer vertical opposing wall portion 13c in the prospective direction. The screw 31 is joined to the outer lower plate portion 16b of the lower reinforcing member 16.

  According to the joinery 1 of 1st Embodiment, the iron vertical provided in the longitudinal direction to the vertical reinforcement 13 adjacent to the stainless steel lower reinforcement 16 provided in the lower glass accommodating part 11a of the summoning fence 11 is provided. Since the reinforcing member 18 is joined at a portion overlapping in the prospective direction, the vertical rod 13 and the summoning rod 11 are not easily detached even if heated by a flame or the like. For this reason, even when the outer shoji 10 and the inner shoji 20 are closed, the frame 5 does not follow the longitudinal direction, and the summing bowl 11 that is almost entirely exposed to the outside is exposed to a flame or the like and melted. Since it is difficult to come off from the downarm 13, it is possible to prevent the indoor and outdoor spaces partitioned by the joinery 1 from being communicated.

  Further, when the outer shoji 10 and the inner shoji 20 are closed, the side where the summon 11 does not face the inner shoji 20 may be directly exposed to the flame in the event of a fire. It is possible to protect the downpile 13 from a flame more effectively.

  In addition, as shown in FIG. 5, the hollow portion 11 e of the summon bowl 11 is provided with a hollow section reinforcing member 32 having a U-shaped cross section made of iron, and the end of the hollow section reinforcing member 32 is bent to A vertical rod facing portion 32a that faces the bottom portion 13d is formed, and a screw 33 that penetrates the vertical rod 13 in the longitudinal direction of the summoning rod 11 is screwed into the vertical rod facing portion 32a, and the vertical rod 13 and the summing rod 11 May be further joined. In this case, even if the joining part of the summoning fence 11 and the longitudinal fence 13 is exposed to the flame, the joining of the summoning fence 11 and the longitudinal fence 13 is more difficult to come off, and the joinery 1 is more excellent in fire resistance. Can be provided.

  In the said embodiment, although the vertical reinforcing material 18 was provided in the outer side of the vertical rod 13, in 2nd Embodiment, it is provided in the side glass accommodating part 13a of the vertical rod 13. FIG. Hereinafter, the same components as those in the first embodiment are denoted by the same reference numerals in the drawings, and the description thereof is omitted.

  The longitudinal reinforcing member 35 used in the fitting 1 of the second embodiment has the same cross-sectional shape as the lower reinforcing member 16 of the first embodiment. That is, as shown in FIGS. 6 and 7, the vertical reinforcing member 35 of the second embodiment includes an inner vertical plate portion 35a facing the inner vertical facing wall portion 13b and an outer vertical plate facing the outer vertical facing wall portion 13c. A portion 35b and a vertical bottom plate portion 35c that is screwed to the vertical rod 13 so as to face the vertical bottom portion 13d are formed in a U-shaped cross section. In the vertical reinforcing member 35 of the second embodiment, the lower edges of the inner vertical plate portion 35a and the outer vertical plate portion 35b are placed on the lower bottom portion 11d of the summing bowl 11, and the vertical bottom plate portion 35c is the summing bowl 11. The extending portion 35d extends downward from the lower glass accommodating portion 11a and is screwed to the vertical rod 13.

  The extending portion 35d is formed so as to cover a part or the whole of the hollow portion 11e of the summoning bowl 11, and the tapping screw 30 penetrating in the longitudinal direction of the summing bowl 11 together with the vertical bowl 13 is provided in the summoning bowl 11. The summing bar 11 and the vertical bar 13 are joined to each other by being screwed into the screw screwing part 11j.

  According to the joinery 1 of the second embodiment, the extending portion 35d of the stainless steel vertical reinforcing member 35 provided in the side glass accommodating portion 13a of the vertical rod 13 adjacent to the summon rod 11 is Since the tapping screw 30 for joining the vertical rod 13 is screwed and fixed to the screw threaded portion 11j of the summoning rod 11, a member for fixing the vertical reinforcing member 35 to the summing rod 11 side is used. Alternatively, it is possible to fix the vertical reinforcing member 35 to the summoning bar 11 without performing a new process. At this time, since the screw threaded portion 11j of the summoning bowl 11 is provided in the hollow portion 11e, it is not immediately exposed directly to the flame when the fitting 1 is exposed to the flame. Further, the screw threaded portion 11j is formed thicker than other portions of the summoning bowl 11, and is provided at a distance in the expected direction from the inner lower hollow forming wall portion 11f and the outer lower hollow forming wall portion 11g. Therefore, it is harder to be melted than a portion exposed to the outside of the housing 10a. For this reason, it is possible to provide the joinery 1 with high fire resistance.

  In addition, as shown in FIG. 8, the hollow portion 11 e of the summon bowl 11 is provided with a hollow section reinforcing member 32 having a U-shaped cross section made of iron, and the end portion of the hollow section reinforcing member 32 is bent to A vertical rod facing surface portion 32a that faces the bottom portion 13d is formed, and a screw 33 in which the extending portion 35d of the vertical reinforcing member 35 is penetrated in the longitudinal direction of the summoning rod 11 is screwed into the vertical rod facing surface portion 32a and the vertical rod. 13 may be further joined to the summon bowl 11. In this case, even if the joining part of the summoning fence 11 and the longitudinal fence 13 is exposed to the flame, the joining of the summoning fence 11 and the longitudinal fence 13 is less likely to come off, and the joinery 1 is more excellent in fire resistance. Can be provided.

  As shown in FIG. 9, the lower reinforcing member 16 is the same as that of the first embodiment in the lower glass accommodating portion 11 a of the summon bowl 11, and the inner lower plate portion 16 a of the lower reinforcing member 16 and the vertical reinforcing member 35 are provided. The inner vertical plate portion 35a may be disposed such that the outer lower plate portion 16b of the lower reinforcing member 16 and the outer vertical plate portion 35b of the vertical reinforcing member 35 are in contact with or in close proximity to each other. In this case, even if the joined portion of the summoning rod 11 and the vertical rod 13 is exposed to the flame and the summoning rod 11 and the vertical rod 13 are melted, the inner and lower plate portions 16a and the inner vertical plate portion 35a are formed. In addition, since the outer lower plate portion 16b and the outer vertical plate portion 35b are engaged with each other and supported to prevent falling, the joining of the summoning ridge 11 and the vertical ridge 13 is more difficult to disengage, and only the vertical reinforcing member 35 is provided. It is possible to improve the fire resistance as compared with the case where is provided. For this reason, it is possible to provide the fitting 1 more excellent in fire resistance.

  In the said embodiment, although it was set as the fitting 1 for the raising / lowering window for ventilation with which the door used for a door etc. is used as a fitting, it does not restrict to this. For example, a joinery in which a shoji is provided on a frame directly provided in a building or the like may be used. Moreover, it is not limited to the joinery for raising and lowering windows, and it may be a sliding window or a joinery for a sliding window. In the case of a single-drawing window, the member that the summoning bowl faces is equivalent to a vertical bone or a wall.

  Moreover, you may provide heating foam materials, such as a thermally expansible graphite, suitably in each glass accommodating part 11a, 12a, 13a, 14a and hollow part 11e, 12e, 13e, 14e.

  In addition, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
