−開き防止構造−
以下、実施形態の樹脂サッシの召合せ部分の開き防止構造について、図を参考にして説明する。
一般に、サッシは、内障子２の召合框２３と外障子３の召合框３４をクレセント６によって拘束しているが、高さ寸法が２０００ｍｍを超える樹脂サッシ等は、図１１に示すように、風等の外圧等によって内障子２の召合框２３と外障子３の召合框３４を見込み方向に離間させる力Ｆ１が生じるなどしてクレセント６に大きなモーメント力Ｆ２がかかり、クレセント６や竪框が変形したり破損する危険性があった。 -Opening prevention structure-
Hereinafter, the opening prevention structure of the combined portion of the resin sash of the embodiment will be described with reference to the drawings.
Generally, the sash restrains the sash 23 of the internal sash 2 and the sash 34 of the external sash 3 by the crescent 6, but the resin sash having a height dimension exceeding 2000 mm is as shown in FIG. A large moment force F2 is applied to the crescent 6 due to the force F1 that separates the sash 23 of the internal sash 2 and the sash 34 of the external sash 3 in the prospective direction due to external pressure such as wind. There was a risk that the sash would be deformed or damaged.

また、図１２（ａ）に示すように、火災時には、各框材の伸びや反り等の変形が発生することによってクレセント６にモーメント力Ｆ３がかかると、クレセント６が変形や破損などして内、外障子２，３の拘束が維持できないことがある。そのため、内、外障子２，３の召合框２３，３４に配置した加熱膨張材ｆが膨張しても、召合框２３，３４間に隙間が生じてしまい、室内外の十分な閉塞ができなかった。 Further, as shown in FIG. 12 (a), in the event of a fire, when a moment force F3 is applied to the crescent 6 due to deformation such as elongation or warpage of each frame material, the crescent 6 is deformed or damaged. , The restraint of the external obstacles 2 and 3 may not be maintained.

内側部材７１は、図１０（ｂ）に示すように、召合框２３の内側部材７１が固定された領域付近において、当接片２３１ｃに欠除部２３１ｄが設けられており、障子の閉鎖時に外障子３の召合框３４に固定した外側部材７２が干渉することを防いでいる。 As shown in FIG. 10B, the inner member 71 is provided with a cutout portion 231d on the contact piece 231c in the vicinity of the region where the inner member 71 of the sash 23 is fixed, and when the shoji is closed. The outer member 72 fixed to the sash 34 of the shoji 3 is prevented from interfering with the outer member 72.

本実施形態の開き防止金具７の外側部材７２は、スチール等の金属材料からなり、図９（ｃ）に示すように、外障子３の召合框３４に固定するための固定部７２ｆと、固定部７２ｆの室内側に配置されて下方向及び内周方向に延設される引掛け部７２ａと、固定部７２ｆに積層されるスペーサ７２ｇを有している。 The outer member 72 of the opening prevention metal fitting 7 of the present embodiment is made of a metal material such as steel, and as shown in FIG. It has a hooking portion 72a arranged on the indoor side of the fixed portion 72f and extending downward and inward, and a spacer 72g laminated on the fixed portion 72f.

外側部材７２は、図９（ａ）に示すように、召合框３４の室外側面にクレセント受６２に隣接して配置され、図１０（ｃ）に示すように、召合わせ框の中空部内に配置される補強部材３４２の室内側見付壁３４２ｂにビスｂにより固定されている。
なお、内側部材７１及び外側部材７２のスペーサ７１ｃ，７２ｇは必ずしも必要ではなく、スペーサ７１ｃ，７２ｇの積層数は、召合わせ框の寸法によって適宜設定すればよい。 The outer member 72 is arranged adjacent to the crescent receiver 62 on the outdoor surface of the mating stile 34 as shown in FIG. 9 (a), and is arranged in the hollow portion of the mating stile as shown in FIG. 10 (c). The reinforcing member 342 to be arranged is fixed to the indoor side finding wall 342b by a screw b.
The spacers 71c and 72g of the inner member 71 and the outer member 72 are not always necessary, and the number of laminated spacers 71c and 72g may be appropriately set according to the dimensions of the combined stile.

召合框３４は、図１０（ｄ）に示すように、外側部材７２が固定された領域付近において、当接片３４１ｃに欠除部３４１ｄが設けられており、障子の閉鎖時に内障子２の召合框２３に固定した内側部材７１が干渉することを防いでいる。 As shown in FIG. 10D, the sash 34 is provided with a cutout portion 341d on the contact piece 341c in the vicinity of the region where the outer member 72 is fixed, and when the sash is closed, the sash 2 is provided with a cutout portion 341d. It prevents the inner member 71 fixed to the sash 23 from interfering with each other.

そして、内、外障子２，３が閉鎖された状態では、図９（ａ），（ｄ）に示すように、内側部材７１の引掛け部７１ａが外側部材７２の引掛け部７２ａの室外側に位置することとなり、風等の外圧や火災時の熱によって框材に反り等の変形が生じても内障子２の召合框２３と外障子３の召合框３４が室内外方向に離間することを防止してクレセント等に過度な力が加わり、クレセントや框等が破壊することを抑制することができる。 Then, in a state where the inner and outer sashes 2 and 3 are closed, as shown in FIGS. 9A and 9D, the hooking portion 71a of the inner member 71 is the outdoor side of the hooking portion 72a of the outer member 72. Even if the stile material is warped or otherwise deformed due to external pressure such as wind or heat during a fire, the sash 23 of the shoji 2 and the stile 34 of the shoji 3 are separated from each other in the indoor and outdoor directions. It is possible to prevent the crescent and the like from being destroyed by applying an excessive force to the crescent and the like.

以上のように、本実施形態にかかる樹脂サッシは、内、外障子２，３の召合せ部に、クレセントに隣接して開き防止部材が設けられているので、風等の外圧によってクレセントに外力がかかっても内障子２の召合框２３と外障子３の召合框３４が室内外方向に離間することを防止して、クレセントが破壊することを抑制することができる。 As described above, in the resin sash according to the present embodiment, since the opening prevention member is provided adjacent to the crescent in the mating portions of the inner and outer sashes 2 and 3, the external force is applied to the crescent by the external pressure such as wind. Even if the sash is applied, it is possible to prevent the sash 23 of the internal sash 2 and the sash 34 of the external sash 3 from separating in the indoor and outdoor directions, and it is possible to prevent the crescent from being destroyed.

また、火災時には、内、外障子２，３の召合框２３，３４が反るなど変形しても、開き止め部材の内側部材７１の引掛け部７１ａと外側部材７２の引掛け部７２ａとが見込み方向に係合して召合框同士が見込み方向に離間することを防止する。
このとき、図１３（ａ）に示すように、内障子２の召合框２３の中空部内に配置された補強部材２３２を介してクレセント錠６１と開き防止金具７の内側部材７１が連結され、外障子３の召合框３４の中空部内に配置された補強部材３４２を介してクレセント受６２と開き防止金具７の外側部材７２が連結されているので、クレセント部分における召合框の補強部材同士の強固な連結を達成しており、図１３（ｂ）に示すように、加熱膨張材による内外の連通を確実に防止することができる。 Further, in the event of a fire, even if the inner and outer sashes 23 and 34 are deformed such as warping, the hooking portion 71a of the inner member 71 of the opening prevention member and the hooking portion 72a of the outer member 72 Engage in the prospective direction to prevent the mating stiles from separating from each other in the prospective direction.
At this time, as shown in FIG. 13A, the crescent lock 61 and the inner member 71 of the opening prevention metal fitting 7 are connected via the reinforcing member 232 arranged in the hollow portion of the sash 23 of the internal sash 2. Since the crescent receiver 62 and the outer member 72 of the opening prevention metal fitting 7 are connected to each other via the reinforcing member 342 arranged in the hollow portion of the sash 34 of the outer sash 3, the reinforcing members of the sash in the crescent portion are connected to each other. As shown in FIG. 13 (b), it is possible to reliably prevent internal and external communication by the heat-expanding material.

また、図１４（ａ）に示すように、召合框２３，３４の上端近傍及び下端近傍に設けられた開き防止金具７は、火災時に、内、外障子２，３の召合框２３，３４が反るなど変形しても、図１４（ｂ）に示すように、開き防止金具７の内側部材７１の引掛け部７１ａと外側部材７２の引掛け部７２ａとが見込み方向に係合して召合框同士が見込み方向に離間すること防止することができる。 Further, as shown in FIG. 14A, the opening prevention metal fittings 7 provided near the upper end and the lower end of the sashes 23 and 34 are provided with the sashes 23 and 3 for the inner and outer sashes in the event of a fire. Even if the 34 is deformed such as warped, as shown in FIG. 14B, the hooking portion 71a of the inner member 71 of the opening prevention metal fitting 7 and the hooking portion 72a of the outer member 72 are engaged in the prospective direction. It is possible to prevent the sashes from separating from each other in the prospective direction.

そして、樹脂材料からなる召合框が火災により溶融した場合にも、同様に開き防止金具７によって召合框の中空部内に配置された補強部材が見込み方向に離間することを抑制し、合わせてガラス間口内の補強部材の分離を抑制することができるので、各補強部材間に加熱膨張材を充満させることができ、召合せ部における室内外の連通を抑制することができる。 Then, even when the mating stile made of the resin material is melted by a fire, the opening prevention metal fitting 7 also suppresses the reinforcing member arranged in the hollow portion of the mating stile from separating in the prospective direction. Since the separation of the reinforcing members in the glass frontage can be suppressed, the heating and expanding material can be filled between the reinforcing members, and the communication between indoors and outdoors in the mating portion can be suppressed.

以上、実施形態の樹脂サッシについて説明したが、樹脂サッシに設けるクレセントの数は２つに限定されるものではなく、また、開き防止部材の数や位置も限定されるものではない。例えば、クレセントは一つでもよく、クレセントの上方に隣接して開き防止部材を設けてもよい。 Although the resin sash of the embodiment has been described above, the number of crescents provided on the resin sash is not limited to two, and the number and positions of the opening prevention members are not limited to two. For example, the crescent may be one, and an opening prevention member may be provided adjacent to the upper part of the crescent.

その他、以上の実施形態は，請求項に記載された発明を限定するものではなく，例示として取り扱われることは言うまでもない。 In addition, it goes without saying that the above embodiments do not limit the invention described in the claims and are treated as examples.
