Description

本発明は、クレセントとクレセント受けとを備える建具に関する。 The present invention relates to a fitting that includes a crescent and a crescent receiver.

特許文献1には、外障子と内障子とをクレセントで施錠可能な上げ下げ窓の建具が開示されている。 Patent Document 1 discloses a hinged window fitting in which an outer shoji and an inner shoji can be locked using crescents.

特許第6023647号公報Patent No. 6023647

上記のような上げ下げ窓は、火災時には、上部室外側に配置される外障子が熱の影響を受け易く、その脱落や下降が懸念される。外障子が脱落等すると、室内外方向に火炎や煙の通り道となる貫通孔が形成されるためである。なお、このような防火上の問題は、左右の障子を引違い可能に構成した引違い窓等の建具においても同様に起こり得る。例えば引違い窓では、火災の影響で障子が傾くと障子と枠の間に隙間を生じ、ここが上記した貫通孔となり得る。 In the above-mentioned lift-down windows, in the event of a fire, the outside shoji screens placed on the outside of the upper room are susceptible to the effects of heat, and there is a concern that they may fall off or fall. This is because when the outside shoji falls off, a through hole is formed through which flame and smoke can pass both indoors and outdoors. Incidentally, such fire prevention problems can similarly occur in fittings such as sliding windows in which the left and right shoji screens are configured to be able to be slid back and forth. For example, in a sliding window, when the shoji tilts due to the influence of a fire, a gap is created between the shoji and the frame, which can become the above-mentioned through hole.

本発明は、上記従来技術の課題を考慮してなされたものであり、防火性能を向上することができる建具を提供することを目的とする。 The present invention has been made in consideration of the problems of the prior art described above, and an object of the present invention is to provide a fitting that can improve fire prevention performance.

本発明の一態様に係る建具は、窓枠と、前記窓枠にスライド可能に支持され、閉鎖時に前記窓枠の室内側に配置される第1障子と、前記窓枠にスライド可能に支持され、閉鎖時に前記窓枠の室外側に配置される第2障子と、前記第1障子に取り付けられた金属製のクレセントと、前記第2障子の召合せ框に取り付けられ、前記クレセントが係合される金属製のクレセント受けと、を備え、前記第2障子の前記召合せ框は、面材の縁部を保持する開口溝と、前記開口溝に配置され、当該召合せ框の長手方向に沿って延在する金属製の開口溝補強材と、前記第2障子のスライド方向に対する前記クレセント受けと前記開口溝補強材との相対移動を規制する規制部材と、を有する。 A fitting according to one aspect of the present invention includes a window frame, a first shoji that is slidably supported by the window frame and is placed on the indoor side of the window frame when closed, and a first shoji that is slidably supported by the window frame. , a second shoji placed on the outdoor side of the window frame when closed, a metal crescent attached to the first shoji, and a metal crescent attached to a joining frame of the second shoji, the crescents being engaged. and a metal crescent holder of the second shoji, and the matching stile of the second shoji has an opening groove that holds an edge of the face material, and a metal crescent holder that is arranged in the opening groove and extends along the longitudinal direction of the matching stile. and a regulating member that restricts relative movement between the crescent receiver and the opening groove reinforcing member in the sliding direction of the second shoji.

本発明の上記態様によれば、防火性能を向上することができる。 According to the above aspect of the present invention, fire prevention performance can be improved.

図4に示すように、ワイヤ55は、例えば金属撚り線である。ワイヤ55は、2本用いられ、障子29,30の左右外方にそれぞれ設けられる。各ワイヤ55は、第1端部55aが外障子29に連結され、第2端部55bが内障子30に連結される。第1端部55aは、端子部材56が固定され、この端子部材56を介して摺動部品54に連結される。第2端部55bは、金属板57が固定され、この金属板57を介して内障子30に連結される。
2.2 Next, a fireproof structure using the wire 55 and the sliding component 54 will be explained.
As shown in FIG. 4, the wire 55 is, for example, a stranded metal wire. Two wires 55 are used and are provided on the left and right outer sides of the shoji screens 29 and 30, respectively. Each wire 55 has a first end 55a connected to the outer shoji 29 and a second end 55b connected to the inner shoji 30. A terminal member 56 is fixed to the first end portion 55a, and the first end portion 55a is connected to the sliding component 54 via the terminal member 56. A metal plate 57 is fixed to the second end portion 55b, and the second end portion 55b is connected to the inner shoji 30 via the metal plate 57.

各ワイヤ55は、端部55a,55b間が滑車58に巻掛けされ、これにより外障子29と内障子30とを互い違いに上下動させる。滑車58は、縦枠28c,28dの金属縦枠33c,33dの枠内側見込み面にねじ止めされる。 Each wire 55 is wound around a pulley 58 between end portions 55a and 55b, thereby causing the outer shoji 29 and the inner shoji 30 to move up and down alternately. The pulley 58 is screwed to the inside facing surfaces of the metal vertical frames 33c and 33d of the vertical frames 28c and 28d.

図3及び図6Aに示すように、摺動部品54は、本体部60と、連結金具61とを有する。本体部60は、連結金具61に装着された樹脂部品であり、縦框39c,39dに対する摺動部となる。 As shown in FIGS. 3 and 6A, the sliding component 54 includes a main body 60 and a connecting fitting 61. As shown in FIGS. The main body portion 60 is a resin component attached to the connecting fitting 61, and serves as a sliding portion for the vertical frames 39c and 39d.

図6A~図7に示すように、連結金具61は、ワイヤ取付片61aと、連結片61bと、中間板部61cとを有する。ワイヤ取付片61aは、ワイヤ55の第1端部55aが連結される部分である。連結片61bは、樹脂製の本体部60の側面、具体的には縦枠28c,28d側とは逆側で下框39b側を向いた見込み面から突き出すように設けられ、下框39bに連結される部分である。中間板部61cは、ワイヤ取付片61aと連結片61bとの間の部分である。 As shown in FIGS. 6A to 7, the connecting fitting 61 includes a wire attachment piece 61a, a connecting piece 61b, and an intermediate plate portion 61c. The wire attachment piece 61a is a portion to which the first end 55a of the wire 55 is connected. The connecting piece 61b is provided so as to protrude from a side surface of the main body part 60 made of resin, specifically, from a prospective surface facing the lower stile 39b on the side opposite to the vertical frames 28c and 28d, and is connected to the lower stile 39b. This is the part where it is done. The intermediate plate portion 61c is a portion between the wire attachment piece 61a and the connection piece 61b.

連結金具61は、ワイヤ取付片61a及び連結片61bがXZ平面に沿って段違いに配置され、その間でXY方向に沿う中間板部61cがY方向に起立している。これにより連結金具61は、全体として略クランク形状の金属板で構成されている。連結金具61の材質は、上記した開口溝補強材48~50や中空部補強材51と同一又は同様でよい。 In the connecting fitting 61, a wire attachment piece 61a and a connecting piece 61b are arranged at different levels along the XZ plane, and an intermediate plate portion 61c extending in the XY direction stands up in the Y direction between them. As a result, the connecting fitting 61 is made of a generally crank-shaped metal plate as a whole. The material of the connecting fitting 61 may be the same as or similar to the above-described opening groove reinforcing materials 48 to 50 and hollow portion reinforcing material 51.

連結金具61には、係止孔62aと、挿入孔62bと、長孔62cとが形成されている。 The connecting fitting 61 is formed with a locking hole 62a, an insertion hole 62b, and a long hole 62c.

係止孔62aは、ワイヤ55の端子部材56を係止するための孔部である。係止孔62aは、ワイヤ取付片61aの長手方向(X方向)に沿って延びている。係止孔62aは、一端部が挿入孔62bに連通し、他端部が長孔62cに連通している。ここで、端子部材56は、ワイヤ55の第1端部55aにねじ止めされるL字状の金属板56aと、金属板56aに形成されたねじ孔に螺合されたねじ56bとを有する。係止孔62aの穴幅は、ねじ56bの軸部56b1の外径よりも大きく、且つ頭部56b2の外径よりも小さい。これにより係止孔62aは、端子部材56のねじ56bを抜け止めした状態で係止することができ(図4及び図9参照)、これによりワイヤ55が摺動部品54に連結される。 The locking hole 62a is a hole portion for locking the terminal member 56 of the wire 55. The locking hole 62a extends along the longitudinal direction (X direction) of the wire attachment piece 61a. One end of the locking hole 62a communicates with the insertion hole 62b, and the other end communicates with the elongated hole 62c. Here, the terminal member 56 includes an L-shaped metal plate 56a that is screwed to the first end 55a of the wire 55, and a screw 56b that is screwed into a screw hole formed in the metal plate 56a. The hole width of the locking hole 62a is larger than the outer diameter of the shaft portion 56b1 of the screw 56b, and smaller than the outer diameter of the head portion 56b2. Thereby, the locking hole 62a can lock the screw 56b of the terminal member 56 in a state where it is prevented from coming off (see FIGS. 4 and 9), thereby connecting the wire 55 to the sliding component 54.

挿入孔62bは、ワイヤ55の端子部材56を挿入するための孔部である。挿入孔62bは、中間板部61cの長手方向(Y方向)に沿って形成されることで、係止孔62aとは異なる面に設けられ、且つ係止孔62aと連通している。挿入孔62bの穴幅は、頭部56b2の外径よりも大きい。これにより挿入孔62bは、端子部材56のねじ56bの頭部56b2を円滑に挿入することができる。挿入孔62bに頭部56b2が挿入されたねじ56bは、図7中に1点鎖線の矢印で示すように、そのまま係止孔62aまで移動させ、軸部56b1を係止孔62aに挿通させた状態で、頭部56b2を係止孔62aに係止することができる。 The insertion hole 62b is a hole portion into which the terminal member 56 of the wire 55 is inserted. The insertion hole 62b is formed along the longitudinal direction (Y direction) of the intermediate plate portion 61c, so that it is provided on a different surface from the locking hole 62a and communicates with the locking hole 62a. The hole width of the insertion hole 62b is larger than the outer diameter of the head 56b2. Thereby, the head portion 56b2 of the screw 56b of the terminal member 56 can be smoothly inserted into the insertion hole 62b. The screw 56b with the head 56b2 inserted into the insertion hole 62b was moved as it is to the locking hole 62a, as shown by the dashed-dotted arrow in FIG. 7, and the shaft portion 56b1 was inserted into the locking hole 62a. In this state, the head 56b2 can be locked in the locking hole 62a.

長孔62cは、係止孔62aで係止された端子部材56の見込み方向での位置を調整するための孔部である。長孔62cは、ワイヤ取付片61aの幅方向(Z方向)、つまり下框39bの見込み方向に沿って延びている。長孔62cは、挿入孔62b側とは逆側で係止孔62aに連通している。長孔62cの穴幅は、係止孔62aの穴幅と略同一でよく、ねじ56bの軸部56b1の外径よりも大きく、且つ頭部56b2の外径よりも小さい。これにより長孔62cは、係止孔62aに抜け止めされたねじ56bを見込み方向に移動させることができる(図9参照)。すなわちワイヤ55は、滑車58に巻掛けられているため、下框39bの見込み方向中心よりも一方側に位置ずれした位置に垂下されている。長孔62cは、このワイヤ55の見込み方向での位置ずれを解消し、ワイヤ55を可能な限り鉛直に垂下させることを可能とする。長孔62cは省略されてもよい。 The elongated hole 62c is a hole portion for adjusting the position of the terminal member 56, which is locked in the locking hole 62a, in the expected direction. The elongated hole 62c extends along the width direction (Z direction) of the wire attachment piece 61a, that is, along the direction in which the lower stile 39b is viewed. The elongated hole 62c communicates with the locking hole 62a on the side opposite to the insertion hole 62b. The hole width of the elongated hole 62c may be approximately the same as the hole width of the locking hole 62a, and is larger than the outer diameter of the shaft portion 56b1 of the screw 56b and smaller than the outer diameter of the head portion 56b2. Thereby, the elongated hole 62c can move the screw 56b, which is retained in the locking hole 62a, in the forward direction (see FIG. 9). That is, since the wire 55 is wound around the pulley 58, it is suspended at a position shifted to one side from the center of the lower stile 39b in the viewing direction. The elongated hole 62c eliminates the positional deviation of the wire 55 in the expected direction and allows the wire 55 to hang down as vertically as possible. The long hole 62c may be omitted.

図7~図9に示すように、ワイヤ取付片61aは、中間板部61c側とは逆側の端部に係止孔62aや長孔62cが開口していない。つまり係止孔62aは、挿入孔62b側とは逆側が長孔62cを介して閉塞されている。換言すれば、係止孔62aは、挿入孔62b側とは逆側が開口しない閉じた孔部である。 As shown in FIGS. 7 to 9, the wire attachment piece 61a does not have a locking hole 62a or a long hole 62c at the end opposite to the intermediate plate portion 61c. That is, the locking hole 62a is closed on the side opposite to the insertion hole 62b via the elongated hole 62c. In other words, the locking hole 62a is a closed hole that does not open on the side opposite to the insertion hole 62b.

図6A~図8に示すように、連結金具61は、さらに、連結片61bに設けられた複数の連結孔63と、中間板部61cに設けられた複数の装着孔64とを有する。装着孔64は、本体部60と連結金具61とを連結するねじ65が挿通される孔部である。連結孔63は、連結金具61を下框39bに固定するねじ66が挿通される孔部である。ねじ66は、連結孔63に挿通された状態で、下框39bの枠外側見込み面39b1に形成された孔部を通して中空部補強材51のねじ孔51bに螺合される。つまり連結金具61は、中空部補強材51に連結されている。この際、ねじ66の頭部は、連結金具61の連結片61bに係止され、その周囲に本体部60等の樹脂部品が配置されていない。 As shown in FIGS. 6A to 8, the connecting fitting 61 further includes a plurality of connecting holes 63 provided in the connecting piece 61b and a plurality of mounting holes 64 provided in the intermediate plate portion 61c. The mounting hole 64 is a hole portion into which a screw 65 connecting the main body portion 60 and the connecting fitting 61 is inserted. The connecting hole 63 is a hole into which a screw 66 for fixing the connecting fitting 61 to the lower stile 39b is inserted. The screw 66 is inserted into the connecting hole 63 and is screwed into the screw hole 51b of the hollow reinforcing member 51 through a hole formed in the outer side of the frame 39b1 of the lower stile 39b. In other words, the connecting fitting 61 is connected to the hollow reinforcing member 51. At this time, the head of the screw 66 is locked to the connecting piece 61b of the connecting fitting 61, and no resin parts such as the main body 60 are arranged around it.

このように、本実施形態の摺動部品54は、樹脂製の本体部60の側面から突出した連結金具61の連結片61bが下框39bに対して直接的にねじ止めされて外障子29に取り付けられる構成としてもよい。これにより下框39bと連結片61bとを連結するねじ66は、周囲が金属部材のみで囲まれ、樹脂製の本体部60から離間した位置に設置される。このため、火災時、建具10は、ねじ66による連結金具61の下框39bに対する連結状態が長時間維持され、ワイヤ55によって外障子29を長時間吊下支持しておくことができる。その結果、建具10は、火災時に外障子29が落下や下降を抑制でき、高い防火性能が得られる。この際、連結金具61は、略クランク形状の金属板で形成された高強度の構造を有するため、一層安定して外障子29を支持できる。特に、連結金具61は、下框39bの中空部補強材51に連結されることで、外障子29の落下や下降を一層抑制できる。 In this way, in the sliding component 54 of this embodiment, the connecting piece 61b of the connecting fitting 61 protruding from the side surface of the resin main body 60 is directly screwed to the lower stile 39b, and is attached to the outer shoji 29. It may also be configured so that it can be attached. As a result, the screw 66 that connects the lower stile 39b and the connecting piece 61b is surrounded only by metal members and is installed at a position spaced apart from the main body 60 made of resin. Therefore, in the event of a fire, the connection of the fittings 61 to the lower stile 39b of the fittings 10 by the screws 66 can be maintained for a long time, and the outer shoji 29 can be suspended and supported by the wires 55 for a long time. As a result, the fittings 10 can prevent the outer shoji 29 from falling or descending in the event of a fire, providing high fire prevention performance. At this time, since the connecting fitting 61 has a high-strength structure formed of a substantially crank-shaped metal plate, it can support the outer shoji 29 more stably. In particular, by connecting the connecting fittings 61 to the hollow reinforcing material 51 of the lower stile 39b, it is possible to further prevent the outer shoji 29 from falling or descending.

また、連結金具61は、係止孔62aから連続する挿入孔62bを有するため、端子部材56のねじ56bの頭部56b2を円滑に連結することができる。このため、建具10は、外障子29を窓枠28に設置する際、端子部材56に予め取り付けたねじ56bを容易に摺動部品54に連結することができる。さらに、ねじ56bは、係止孔62aに係止された際、下から上に向かう姿勢となる。このため、ねじ56bは、係止孔62aに係止後に頭部56b2をドライバ等の工具で容易に回転させることができ、外障子29の高さ位置の微調整も容易であり、外障子29の組付効率を向上させることができる。 Further, since the connecting fitting 61 has an insertion hole 62b continuous from the locking hole 62a, the head 56b2 of the screw 56b of the terminal member 56 can be connected smoothly. Therefore, when installing the outer shoji 29 on the window frame 28, the fittings 10 can easily connect the screws 56b attached to the terminal member 56 in advance to the sliding component 54. Further, when the screw 56b is locked in the locking hole 62a, the screw 56b assumes a position facing upward from the bottom. Therefore, after the screw 56b is locked in the locking hole 62a, the head 56b2 can be easily rotated with a tool such as a screwdriver, and the height position of the outer shoji 29 can be easily finely adjusted. Assembling efficiency can be improved.

この際、挿入孔62bが係止孔62aとは異なる面に設けられていることで、火災時等にワイヤ55がX方向に揺れた場合に挿入孔62bから脱落することを抑制できる。挿入孔62bを設ける面は、Y方向に起立した中間板部61cに限られず、例えば連結片61bでもよい。連結金具61はクランク形状以外でもよく、この場合も挿入孔62bは係止孔62aと異なる面に設けられるとよい。 At this time, since the insertion hole 62b is provided on a different surface from the locking hole 62a, it is possible to prevent the wire 55 from falling out of the insertion hole 62b when the wire 55 swings in the X direction during a fire or the like. The surface on which the insertion hole 62b is provided is not limited to the intermediate plate portion 61c standing up in the Y direction, and may be, for example, the connecting piece 61b. The connecting fitting 61 may have a shape other than a crank shape, and in this case as well, the insertion hole 62b is preferably provided on a different surface from the locking hole 62a.

2.3 次に、クレセント受け70を用いた防火構造を説明する。
図3~図5、図10A及び図10Bに示すように、外障子29の下框39bは、クレセント受け70が取り付けられている。クレセント受け70は、内障子30の框体41の上框41a(図1参照)の枠外側見込み面に取り付けられたクレセント71が係合される金属部品である。クレセント受け70は、外障子29の召合せ框となる下框39bの長手方向の略中央部に取り付けられている。クレセント受け70は、ステンレスやスチール等の金属板に折り曲げ、切り抜き、及び切り起こし等を形成したものである。クレセント受け70及びクレセント71は、例えばステンレス等の金属製である。
2.3 Next, a fireproof structure using the crescent receiver 70 will be explained.
As shown in FIGS. 3 to 5, FIGS. 10A and 10B, a crescent receiver 70 is attached to the lower stile 39b of the outer shoji 29. The crescent receiver 70 is a metal component that is engaged with a crescent 71 attached to the outer side of the frame of the upper stile 41a (see FIG. 1) of the stile body 41 of the inner sash 30. The crescent receiver 70 is attached to a substantially central portion in the longitudinal direction of a lower stile 39b that serves as a joining stile for the outer shoji 29. The crescent receiver 70 is formed by bending, cutting out, cutting and raising a metal plate such as stainless steel or steel. The crescent receiver 70 and the crescent 71 are made of metal such as stainless steel.

図5、図10A及び図10Bに示すように、クレセント受け70は、取付部70aと、係合部70bとを有する。 As shown in FIGS. 5, 10A, and 10B, the crescent receiver 70 includes a mounting portion 70a and an engaging portion 70b.

取付部70aは、略矩形状の金属板であり、XY平面に沿って配置される。取付部70aには、左右一対のねじ孔70cが形成されている。ねじ孔70cは、クレセント受け70を下框39bに固定するためのねじ72が螺合される。取付部70aは、開口溝45を形成する一対の壁部のうち、一方の室内側壁部74に固定される。 The attachment portion 70a is a substantially rectangular metal plate and is arranged along the XY plane. A pair of left and right screw holes 70c are formed in the mounting portion 70a. A screw 72 for fixing the crescent receiver 70 to the lower stile 39b is screwed into the screw hole 70c. The attachment portion 70a is fixed to one of the indoor wall portions 74 of the pair of wall portions forming the opening groove 45.

係合部70bは、取付部70aから室外側に多少屈曲しつつ上方に向って突出した後、室内側に向かって2回屈曲されることで、下向きのフック形状に形成されている。係合部70bは、クレセント71が係合されると、このクレセント71を上から把持したように吊下支持された係合状態となる。 The engaging portion 70b is formed into a downward hook shape by projecting upward from the attachment portion 70a while being slightly bent toward the outdoor side, and then bent twice toward the indoor side. When the engaging portion 70b is engaged with the crescent 71, the engaging portion 70b is in an engaged state in which the crescent 71 is suspended and supported as if it were gripped from above.

下框39bは、クレセント受け70が取り付けられる室内側壁部74に孔部74aを有する。孔部74aは、ねじ72を挿通可能な貫通孔であり、いわゆるバカ穴である。また、下框39bの開口溝45に配置された開口溝補強材49は、その長手方向の略中央部に切り起こし片49aを有する。切り起こし片49aは、開口溝補強材49の見込み面を形成する底板の一部を切り欠いて枠外側へと屈曲させた板片である。開口溝補強材49は、室内側壁部74と対向する室内側突出片49bに規制穴49cを有する。規制穴49cは、室内側突出片49bの切り起こし片49aを含む部分に形成されている。 The lower stile 39b has a hole 74a in the indoor wall 74 to which the crescent receiver 70 is attached. The hole 74a is a through hole through which the screw 72 can be inserted, and is a so-called blank hole. Further, the opening groove reinforcing material 49 disposed in the opening groove 45 of the lower stile 39b has a cut-and-raised piece 49a at approximately the center in the longitudinal direction. The cut-and-raised piece 49a is a plate piece obtained by cutting out a part of the bottom plate that forms the prospective surface of the opening groove reinforcing material 49 and bending it to the outside of the frame. The opening groove reinforcing material 49 has a regulating hole 49c in the indoor side protruding piece 49b facing the indoor side wall part 74. The regulation hole 49c is formed in a portion of the indoor side projecting piece 49b that includes the cut and raised piece 49a.

クレセント受け70の取付部70aは、下框39bの室内側壁部74と、開口溝補強材49の室内側突出片49bとの間に挟み込まれた状態で、ねじ72により室内側壁部74と締結される。具体的には、ねじ72は、室内側から室外側に向かって孔部74aに挿通された状態でねじ孔70cに螺合され、ねじ孔70cを挿通した先端部が規制穴49cに挿入される。 The mounting portion 70a of the crescent receiver 70 is fastened to the indoor wall portion 74 with screws 72 while being sandwiched between the indoor wall portion 74 of the lower stile 39b and the indoor protruding piece 49b of the opening groove reinforcing material 49. Ru. Specifically, the screw 72 is inserted into the hole 74a from the indoor side to the outdoor side, and then screwed into the screw hole 70c, and the tip end inserted through the screw hole 70c is inserted into the regulation hole 49c. .

このように、ねじ72は、クレセント受け70を下框39bに締結した状態で、先端部が規制穴49cに挿入され、XY方向に係止される構成としてもよい。そうすると、ねじ72は、クレセント受け70と開口溝補強材49との間の上下方向への相対移動を規制する規制部材として機能する。 In this way, the screw 72 may have a configuration in which the tip end is inserted into the regulation hole 49c and locked in the XY direction with the crescent receiver 70 fastened to the lower stile 39b. Then, the screw 72 functions as a regulating member that regulates relative movement in the vertical direction between the crescent receiver 70 and the opening groove reinforcing member 49.

例えば建具10が室外からの火災の影響を受けると、窓枠28の上部室外側にある外障子29は内障子30よりも高温になり易く、框体39が軟化する可能性がある。本実施形態の建具10は、このように外障子29の框体39が軟化した場合であっても、外障子29よりも熱影響を受けにくい内障子30に締結されたクレセント71でクレセント受け70の下への移動が規制される。そして、ねじ72は、面材38の下縁部を保持する開口溝補強材49とクレセント受け70との上下方向の相対移動を規制している。すなわち、開口溝補強材49は、ねじ72を介してクレセント71に吊下支持された状態となっているため、面材38や外障子29自体の落下や下降を抑制できる。このようにクレセント受け70と開口溝補強材49との相対移動を規制する規制部材は、所定の強度を有する金属部材等であればねじ以外でもよい。また、規制穴49cは、上方が閉じた切欠き穴等でもよい。 For example, when the fittings 10 are affected by a fire from outside, the outer shoji 29 located on the upper outdoor side of the window frame 28 tends to reach a higher temperature than the inner shoji 30, and the frame body 39 may become soft. In the fittings 10 of this embodiment, even if the frame 39 of the outer shoji 29 is softened, the crescent receiver 70 is connected to the crescent 71 that is connected to the inner shoji 30 which is less susceptible to heat effects than the outer shoji 29. Movement below is regulated. The screw 72 restricts relative movement in the vertical direction between the opening groove reinforcing material 49 that holds the lower edge of the face member 38 and the crescent receiver 70. That is, since the opening groove reinforcing material 49 is suspended and supported by the crescent 71 via the screws 72, it is possible to suppress the falling and lowering of the facing material 38 and the outer shoji 29 themselves. The regulating member that regulates the relative movement between the crescent receiver 70 and the opening groove reinforcing member 49 in this manner may be other than a screw as long as it is a metal member or the like having a predetermined strength. Further, the regulation hole 49c may be a notch hole or the like whose upper part is closed.

上記したように、規制穴49cは、室内側突出片49bの切り起こし片49aを含む部分に形成されている。このため、図3に示すように、ねじ72は、規制穴49cに安定して係止できるように、十分な長さのものを用いても、規制穴49cを抜けた先端が面材38やその下縁部を保持するガスケット等に干渉することを防止できる。 As described above, the regulation hole 49c is formed in the portion of the indoor side protruding piece 49b that includes the cut and raised piece 49a. For this reason, as shown in FIG. 3, even if the screw 72 is long enough to be stably locked in the regulation hole 49c, the tip of the screw 72 that passes through the regulation hole 49c will end up in the face material 38 or It is possible to prevent interference with a gasket etc. that holds the lower edge.

なお、建具10は、上記したワイヤ55による連結金具61を介して下框39bの吊下による防火構造と合わせて、クレセント受け70による防火構造も備えることが好ましい。そうすると、ワイヤ55によって下框39bの左右両端部を支持でき、クレセント受け70によって下框39bの中央部を支持できるため、下框39bがバランスよく3点支持される。その結果、建具10は、面材38や外障子29の落下や下降を一層抑制できる。 In addition, it is preferable that the fittings 10 also include a fireproof structure by the crescent receiver 70 in addition to the fireproof structure by suspending the lower stile 39b via the connecting metal fittings 61 by the wires 55 described above. Then, the wires 55 can support both left and right ends of the lower stile 39b, and the crescent receiver 70 can support the center of the lower stile 39b, so the lower stile 39b is supported at three points in a well-balanced manner. As a result, the fittings 10 can further suppress falling and lowering of the facing material 38 and the outer shoji 29.

ところで、ねじ72の先端部は、開口溝補強材49の規制穴49cに挿入されているだけである。このため、仮に火災時に下框39bが変形し、開口溝補強材49が室外側に移動した場合は、ねじ72が規制穴49cから脱落する懸念もある。 By the way, the tip of the screw 72 is simply inserted into the regulation hole 49c of the opening groove reinforcing member 49. For this reason, if the lower stile 39b is deformed in the event of a fire and the opening groove reinforcing material 49 moves to the outdoor side, there is a risk that the screw 72 may fall out from the regulation hole 49c.

そこで、図10A及び図10Bに示す構成例では、2本のねじ72を跨ぐように追加した2本のねじ76を備える。下框39bの室内側壁部74には、各ねじ76が挿通される孔部74bが形成され、開口溝補強材49には各ねじ76が螺合されるねじ孔49dが形成されている。ねじ76は、孔部74bを挿通した状態でねじ孔49dに螺合される。これにより下框39bと開口溝補強材49とが締結され、開口溝補強材49の室外側への移動が規制されるため、ねじ72が規制穴49cから脱落することを確実に抑制できる。例えばねじ72を十分深くまで規制穴49cに挿入できる場合等には、図11に示すように、ねじ76、孔部74b及びねじ孔74dは省略してもよい。 Therefore, in the configuration example shown in FIGS. 10A and 10B, two additional screws 76 are provided so as to straddle the two screws 72. A hole 74b into which each screw 76 is inserted is formed in the indoor side wall 74 of the lower stile 39b, and a screw hole 49d into which each screw 76 is screwed is formed in the opening groove reinforcing material 49. The screw 76 is inserted into the hole 74b and is screwed into the screw hole 49d. As a result, the lower stile 39b and the opening groove reinforcing member 49 are fastened together, and movement of the opening groove reinforcing member 49 toward the outdoor side is restricted, so that it is possible to reliably prevent the screw 72 from falling out of the regulating hole 49c. For example, if the screw 72 can be inserted into the regulation hole 49c to a sufficient depth, the screw 76, the hole 74b, and the screw hole 74d may be omitted, as shown in FIG. 11.

クレセント受け70と開口溝補強材49との連結構造は、図10A~図11に示す構成例以外でもよい。例えば図12A及び図12Bに示す連結構造は、クレセント受け70と開口溝補強材49とを裏板78を用いて締結した構成である。裏板78は、開口溝補強材49の規制穴49cと同軸上にねじ孔78aを有する。なお、クレセント受け70は、ねじ孔70cに代えて、いわゆるバカ穴である挿通孔70dを有する。 The connection structure between the crescent receiver 70 and the opening groove reinforcing member 49 may be other than the configuration examples shown in FIGS. 10A to 11. For example, the connection structure shown in FIGS. 12A and 12B has a configuration in which the crescent receiver 70 and the opening groove reinforcing material 49 are fastened together using a back plate 78. The back plate 78 has a screw hole 78a coaxially with the regulation hole 49c of the opening groove reinforcing member 49. Note that the crescent receiver 70 has an insertion hole 70d, which is a so-called blank hole, instead of the screw hole 70c.

従って、図12A及び図12Bに示す構成例では、ねじ72は、室内側から室外側に向かって、孔部74a、挿通孔70d及び規制穴49cに挿通された状態で裏板78のねじ孔78aに螺合される。これにより、この構成でも、ねじ72は、クレセント受け70を下框39bに締結した状態で、先端部が規制穴49cで係止されるため、面材38や外障子29の落下や下降を抑制できる。 Therefore, in the configuration example shown in FIGS. 12A and 12B, the screw 72 is inserted into the screw hole 78a of the back plate 78 from the indoor side toward the outdoor side through the hole 74a, the insertion hole 70d, and the regulation hole 49c. is screwed into the As a result, even in this configuration, the tips of the screws 72 are locked in the regulation holes 49c when the crescent receiver 70 is fastened to the lower stile 39b, so that falling and lowering of the facing material 38 and the outer shoji 29 is suppressed. can.

2.4 次に、連結金具61を用いた防火構造とクレセント受け70を用いた防火構造とを連係させた防火構造を説明する。
上記したように、火災時に高温になり易い外障子29は、連結金具61がワイヤ55を介して滑車58及び内障子30によって支持され、クレセント受け70がクレセント71を介して内障子30によって支持されることで、高い防火性能を有する。本実施形態の建具10は、さらに、これら2つの防火構造同士を連係させ、防火性能を一層向上させることができる構造を備えてもよい。
2.4 Next, a fire protection structure in which a fire protection structure using the connecting metal fittings 61 and a fire protection structure using the crescent receiver 70 are linked will be described.
As described above, the outer shoji 29, which easily becomes hot in the event of a fire, has the connecting fitting 61 supported by the pulley 58 and the inner shoji 30 via the wire 55, and the crescent receiver 70 supported by the inner shoji 30 via the crescent 71. This provides high fire protection performance. The fittings 10 of the present embodiment may further include a structure in which these two fire protection structures are linked together to further improve fire protection performance.

図3~図6Bに示すように、外障子29では、クレセント受け70と連結された開口溝補強材49が中空部補強材51と連結されている。開口溝補強材49は、X方向でクレセント受け70を跨ぐ位置に一対の孔部49eを有する。中空部補強材51は、各孔部49eと上下方向にオーバーラップする位置にねじ孔51aを有する。ねじ孔51aは、中空部補強材51の上側の板部に形成されている。 As shown in FIGS. 3 to 6B, in the outer shoji 29, the opening groove reinforcement 49 connected to the crescent receiver 70 is connected to the hollow reinforcement 51. The open groove reinforcing material 49 has a pair of holes 49e at positions straddling the crescent receiver 70 in the X direction. The hollow part reinforcing material 51 has screw holes 51a at positions that vertically overlap each hole 49e. The screw hole 51a is formed in the upper plate portion of the hollow reinforcing member 51.

従って、外障子29は、ねじ80を開口溝補強材49の上から孔部49eに挿通させ、ねじ孔51aに螺合させることで、開口溝補強材49と中空部補強材51とが連結される。なお、下框39bの開口溝45と中空部46とを仕切る壁部には、孔部49e及びねじ孔51aと同軸上に貫通孔が形成され、ねじ80は孔部49eとこの貫通孔を通してねじ孔51aに螺合される。 Therefore, in the outer shoji 29, the opening groove reinforcing material 49 and the hollow part reinforcing material 51 are connected by inserting the screw 80 into the hole 49e from above the opening groove reinforcing material 49 and screwing it into the screw hole 51a. Ru. In addition, a through hole is formed in the wall that partitions the opening groove 45 and the hollow part 46 of the lower stile 39b coaxially with the hole part 49e and the screw hole 51a, and the screw 80 is screwed through the hole part 49e and this through hole. It is screwed into the hole 51a.

上記のようにクレセント受け70と開口溝補強材49を介して連結された中空部補強材51は、摺動部品54の連結金具61とも連結されている。中空部補強材51は、連結金具61の連結片61bに形成された各連結孔63と上下方向にオーバーラップする位置にねじ孔51bを有する。ねじ孔51bは、中空部補強材51の下側の板部に形成されている。 The hollow reinforcing member 51 connected to the crescent receiver 70 via the opening groove reinforcing member 49 as described above is also connected to the connecting fitting 61 of the sliding component 54. The hollow portion reinforcing member 51 has screw holes 51b at positions that vertically overlap with each connection hole 63 formed in the connection piece 61b of the connection fitting 61. The screw hole 51b is formed in the lower plate portion of the hollow reinforcing member 51.

従って、外障子29は、ねじ66を連結片61bの下から連結孔63に挿通させ、ねじ孔51bに螺合させることで、開口溝補強材49と連結金具61とが連結される。なお、下框39bの下面である枠外側見込み面39b1を形成する壁部には、ねじ孔51b及び連結孔63と同軸上に貫通孔が形成され、ねじ66はこの貫通孔を通して設置される。 Therefore, in the outer shoji 29, the opening groove reinforcing material 49 and the connecting fitting 61 are connected by inserting the screw 66 into the connecting hole 63 from below the connecting piece 61b and screwing it into the screw hole 51b. In addition, a through hole is formed coaxially with the screw hole 51b and the connecting hole 63 in the wall portion forming the frame outer facing surface 39b1, which is the lower surface of the lower stile 39b, and the screw 66 is installed through this through hole.

このように、外障子29は、クレセント受け70から連結金具61までが金属製の開口溝補強材49、中空部補強材51、及び金属製のねじ72,80,66で連結される。これにより外障子29は、下框39bの左右両端部を吊下支持するワイヤ55及び連結金具61と、下框39bの中央部を吊下支持するクレセント71及びクレセント受け70との間が全て金属部材によって連結される。その結果、建具10は、一層高い防火性能が得られ、面材38や外障子29の落下や下降を一層抑制できる。 In this manner, the outer shoji 29 is connected from the crescent receiver 70 to the connecting fitting 61 with the metal opening groove reinforcing material 49, the hollow part reinforcing material 51, and the metal screws 72, 80, and 66. As a result, in the outer shoji 29, the wires 55 and connecting fittings 61 that suspend and support the left and right ends of the lower stile 39b, and the crescents 71 and crescent receivers 70 that suspend and support the center of the lower stile 39b are all made of metal. connected by members. As a result, the fittings 10 can achieve even higher fire prevention performance, and can further suppress falling and lowering of the facing material 38 and the outer shoji 29.

2.5 次に、外障子29の下框39bの開口溝補強材49と他の框39a,39c,39dの開口溝補強材48,50との連結による防火構造を説明する。
上記したように、火災時に高温になり易い外障子29は、上記した連結金具61やクレセント受け70を用いた防火構造と共に、又はこれに代えて、各框39a~39dの開口溝補強材48~50同士を適宜連結することで、防火性能を向上させることができる構造を備えてもよい。
2.5 Next, a fire prevention structure by connecting the opening groove reinforcing material 49 of the lower stile 39b of the outer shoji 29 with the opening groove reinforcing materials 48 and 50 of the other frames 39a, 39c, and 39d will be described.
As described above, the outer shoji 29, which easily becomes hot in the event of a fire, has a fireproof structure using the above-mentioned connecting fittings 61 and crescent receivers 70, or in place of this, the opening groove reinforcing materials 48 to 39 of each frame 39a to 39d. A structure may be provided in which fire prevention performance can be improved by appropriately connecting 50 comrades.

先ず、図3~図6Bに示すように、下框39bの中空部補強材51は、縦框39c,39dの開口溝補強材50とそれぞれ連結されている。なお、図4~図6Bでは、一方の縦框39cの開口溝補強材50と中空部補強材51との連結構造を例示しているが、他方の縦框39dの開口溝補強材50と中空部補強材51との連結構造はこれと左右対称構造でよい。 First, as shown in FIGS. 3 to 6B, the hollow reinforcing material 51 of the lower stile 39b is connected to the opening groove reinforcing material 50 of the vertical stile 39c, 39d, respectively. Note that FIGS. 4 to 6B illustrate a connection structure between the opening groove reinforcing material 50 of one vertical stile 39c and the hollow reinforcing material 51, but the connecting structure between the opening groove reinforcing material 50 of the other vertical stile 39d and the hollow reinforcing material 51 is illustrated. The connection structure with the partial reinforcement member 51 may be a symmetrical structure.

縦框39c,39dの開口溝補強材50は、全長の大部分が断面コ字状の金属板であるが、下端部に略L字状の屈曲片50aを有する。屈曲片50aは、開口溝補強材50の見込み面を形成する板部の一部を下方に突出させると共に、枠内側に屈曲させた板片である。屈曲片50aのXZ平面に沿う板部には、ねじ孔50bが形成されている。中空部補強材51は、ねじ孔50bと上下方向にオーバーラップする左右端部に孔部51cを有する。孔部51cは、中空部補強材51の上側の板部に形成されている。 The opening groove reinforcing material 50 of the vertical frames 39c and 39d is a metal plate having a U-shaped cross section over most of its entire length, but has a substantially L-shaped bent piece 50a at its lower end. The bent piece 50a is a plate piece in which a part of the plate part forming the prospective surface of the opening groove reinforcing material 50 is made to protrude downward and is bent inward of the frame. A screw hole 50b is formed in the plate portion of the bent piece 50a along the XZ plane. The hollow portion reinforcing material 51 has holes 51c at left and right end portions that vertically overlap the screw holes 50b. The hole portion 51c is formed in the upper plate portion of the hollow portion reinforcing member 51.

ここで、本実施形態の框体39は、縦框39c,39dの開口溝47に下框39bの左右両端部を印籠した縦勝ち構造を採用している。このため、中空部補強材51を開口溝補強材50の枠内側見込み面に突き当てると、屈曲片50aが開口溝45に小口から挿入され、中空部補強材51の枠内側見込み面である上面とオーバーラップする。なお、屈曲片50aと中空部補強材51との間には、下框39bの開口溝45と中空部46とを仕切る壁部を介在する。つまり屈曲片50aが開口溝45に小口から挿入される。 Here, the frame body 39 of this embodiment employs a vertical structure in which both left and right ends of the lower frame 39b are sealed in the opening grooves 47 of the vertical frames 39c and 39d. Therefore, when the hollow part reinforcing material 51 is butted against the frame inner side of the opening groove reinforcing material 50, the bent piece 50a is inserted into the opening groove 45 from the edge, and the upper surface of the hollow part reinforcing material 51, which is the frame inner side of the opening, is inserted into the opening groove 45 from the edge. overlap with. Note that a wall portion that partitions the opening groove 45 of the lower stile 39b and the hollow portion 46 is interposed between the bent piece 50a and the hollow portion reinforcing member 51. That is, the bent piece 50a is inserted into the opening groove 45 from the edge.

従って、外障子29は、ねじ82を下から孔部51cに挿通させ、ねじ孔50bに螺合させることで、中空部補強材51と開口溝補強材50とが連結される。その結果、縦框39c,39dの開口溝補強材50が、中空部補強材51を介して下框39bの開口溝補強材49とも連結される。つまり下框39bの開口溝補強材49と縦框39c,39dの開口溝補強材50とが相対的に連結される。勿論、開口溝補強材49,50同士が直接的に連結されてもよい。なお、下框39bの開口溝45と中空部46とを仕切る壁部には、孔部51c及びねじ孔50bと同軸上に貫通孔が形成され、ねじ82はこの貫通孔を通して設置される。 Therefore, in the outer shoji 29, the hollow part reinforcing material 51 and the opening groove reinforcing material 50 are connected by inserting the screws 82 from below into the holes 51c and screwing them into the screw holes 50b. As a result, the opening groove reinforcing members 50 of the vertical frames 39c and 39d are also connected to the opening groove reinforcing members 49 of the lower stile 39b via the hollow portion reinforcing members 51. That is, the opening groove reinforcing material 49 of the lower stile 39b and the opening groove reinforcing material 50 of the vertical stile 39c, 39d are relatively connected. Of course, the opening groove reinforcing members 49 and 50 may be directly connected to each other. Note that a through hole is formed in the wall that partitions the opening groove 45 and the hollow portion 46 of the lower stile 39b coaxially with the hole portion 51c and the screw hole 50b, and the screw 82 is installed through this through hole.

次に、図3、図13A及び図13Bに示すように、上框39aの開口溝補強材48は、縦框39c,39dの開口溝補強材50とそれぞれ連結されている。なお、図13A及び図13Bでは、一方の縦框39cの開口溝補強材50と開口溝補強材48との連結構造を例示しているが、他方の縦框39dの開口溝補強材50と開口溝補強材48との連結構造はこれと左右対称構造でよい。 Next, as shown in FIGS. 3, 13A, and 13B, the opening groove reinforcing material 48 of the upper stile 39a is connected to the opening groove reinforcing material 50 of the vertical stile 39c, 39d, respectively. Note that FIGS. 13A and 13B illustrate a connection structure between the opening groove reinforcing material 50 of one vertical stile 39c and the opening groove reinforcing material 48; The connection structure with the groove reinforcing material 48 may be symmetrical with this structure.

上框39aの開口溝補強材48は、全長の大部分が断面コ字状の金属板であるが、左右の両端部に略L字状の折曲片48aを有する。折曲片48aは、開口溝補強材48の見込み面に沿う板部の一部を延長すると共に、上方に向かって折り曲げたXY方向に沿う板片である。折曲片48aのXY平面に板部には、ねじ孔48bが形成されている。 The opening groove reinforcing material 48 of the upper stile 39a is a metal plate having a U-shaped cross section over most of its entire length, but has approximately L-shaped bent pieces 48a at both left and right ends. The bent piece 48a is a plate piece that extends a part of the plate portion along the prospective surface of the opening groove reinforcing material 48 and is bent upward in the XY direction. A screw hole 48b is formed in the plate portion of the bent piece 48a on the XY plane.

縦框39c,39dの開口溝補強材50は、見込み面に沿う板部の上端部の一部に突出片50cを有する。突出片50cは、開口溝補強材50の見込み面の一部を上方に突出させた部分である。突出片50cには、孔部50dが形成されている。 The opening groove reinforcing material 50 of the vertical frames 39c and 39d has a protruding piece 50c at a part of the upper end of the plate portion along the prospective surface. The protruding piece 50c is a portion of the prospective surface of the opening groove reinforcing material 50 that protrudes upward. A hole 50d is formed in the protruding piece 50c.

ここで、本実施形態の框体39は、縦框39c,39dの開口溝47に上框39aの左右両端部を印籠した縦勝ち構造を採用している。このため、開口溝補強材48を開口溝補強材50の枠内側見込み面に突き当てると、折曲片48aが突出片50cの見込み面に対向配置され、ねじ孔48bと孔部50dとが同軸配置される。従って、外障子29は、ねじ84を枠外側から枠内側に向かって孔部50dに挿通させ、ねじ孔48bに螺合させることで、開口溝補強材48と開口溝補強材50とが連結される。その結果、縦框39c,39dの開口溝補強材50が、上框39aの開口溝補強材48とも連結される。 Here, the frame body 39 of this embodiment employs a vertical structure in which both left and right ends of the upper frame 39a are sealed in the opening grooves 47 of the vertical frames 39c and 39d. Therefore, when the opening groove reinforcing material 48 is abutted against the inner side of the frame of the opening groove reinforcing material 50, the bent piece 48a is placed opposite to the expected surface of the protruding piece 50c, and the screw hole 48b and the hole 50d are coaxial. Placed. Therefore, in the outer shoji 29, the opening groove reinforcing material 48 and the opening groove reinforcing material 50 are connected by inserting the screw 84 into the hole 50d from the outside of the frame toward the inside of the frame and screwing it into the screw hole 48b. Ru. As a result, the opening groove reinforcing material 50 of the vertical stile 39c, 39d is also connected to the opening groove reinforcing material 48 of the upper stile 39a.

なお、上框39aと縦框39c,39dとを連結する際は、例えば上記のように開口溝補強材48,50をねじ84で連結した後、開口溝補強材48の外側から上框39aを被せ、開口溝補強材50の外側から縦框39c,39dを被せる。そして、上框39aと縦框39c,39dとをねじ86で締結する(図3も参照)。これにより、上框39aと縦框39c,39dとが、互いの開口溝補強材48,50同士が連結された状態で連結される。図13A中の参照符号87は、開口溝補強材48と上框39aとを締結するねじであり、参照符号88は、開口溝補強材50と縦框39c(39d)とを締結するねじである。 In addition, when connecting the upper stile 39a and the vertical stile 39c, 39d, for example, after connecting the opening groove reinforcing members 48, 50 with the screws 84 as described above, the upper stile 39a is connected from the outside of the opening groove reinforcing member 48. Cover the vertical frames 39c and 39d from the outside of the opening groove reinforcing material 50. Then, the upper stile 39a and the vertical stile 39c, 39d are fastened with screws 86 (see also FIG. 3). Thereby, the upper stile 39a and the vertical stile 39c, 39d are connected with each other's opening groove reinforcing members 48, 50 connected to each other. Reference numeral 87 in FIG. 13A is a screw that fastens the opening groove reinforcing material 48 and the upper stile 39a, and reference numeral 88 is a screw that fastens the opening groove reinforcing material 50 and the vertical stile 39c (39d). .

このように、外障子29は、下框39bと左右の縦框39c,39dの開口溝補強材49,50同士が中空部補強材51を介して連結され、上框39aと左右の縦框39c,39dの開口溝補強材48,50同士が連結される。これにより外障子29は、四周の框39a~39dの開口溝補強材48~50間が一体的に連結され、開口溝補強材48~50が実質的に高剛性の枠体を形成する。その結果、外障子29は、四周の開口溝補強材48~50が強固に面材38を保持することができる。さらに、外障子29は、連結金具61やクレセント受け70と連結された下框39bの開口溝補強材49を他の開口溝補強材48,50で支持することができる。その結果、建具10は、一層高い防火性能が得られ、面材38や外障子29の落下や下降をより一層抑制できる。 In this way, in the outer shoji 29, the lower stile 39b and the opening groove reinforcements 49, 50 of the left and right vertical stile 39c, 39d are connected via the hollow reinforcement 51, and the upper stile 39a and the left and right vertical stile 39c are connected to each other via the hollow reinforcement 51. , 39d are connected to each other. As a result, in the outer shoji 29, the opening groove reinforcing members 48 to 50 of the four circumferential frames 39a to 39d are integrally connected, and the opening groove reinforcing members 48 to 50 substantially form a highly rigid frame. As a result, in the outer shoji 29, the opening groove reinforcing members 48 to 50 around the four circumferences can firmly hold the face material 38. Further, in the outer shoji 29, the opening groove reinforcing member 49 of the lower stile 39b connected to the connecting fitting 61 and the crescent receiver 70 can be supported by other opening groove reinforcing members 48 and 50. As a result, the fittings 10 can achieve even higher fire prevention performance, and can further suppress falling and lowering of the facing material 38 and the outer shoji 29.

特に、外障子29は、通風ユニット16の構成要素であり、建物躯体に固定される開口枠12よりも軟化し易い戸体框20に支持されているため、その脱落が一層懸念される。そこで、ワイヤ55で吊られた下框39bの開口溝補強材49と他の框39a,39c,39dの開口溝補強材48,50とを連結しておくことで、面材38や外障子29の脱落防止効果が一層向上する。 In particular, since the outer shoji 29 is a component of the ventilation unit 16 and is supported by the door frame 20, which is more easily softened than the opening frame 12 fixed to the building frame, there is a greater concern that the outer shoji 29 will fall off. Therefore, by connecting the opening groove reinforcing material 49 of the lower stile 39b suspended by the wire 55 to the opening groove reinforcing materials 48 and 50 of the other stile 39a, 39c, and 39d, it is possible to The effect of preventing the material from falling off is further improved.

2.6 次に、建具10が備える他の防火構造について説明する。
本実施形態の建具10は、上記した各防火構造と共に、又はこれらに代えて、他の防火構造を備えてもよい。
2.6 Next, other fire protection structures included in the fittings 10 will be explained.
The fittings 10 of this embodiment may include other fire protection structures in addition to or in place of each of the fire protection structures described above.

先ず、図14に示すように、内障子30は、閉塞時には、框体41の下框41bの下部が窓枠28の下枠28bの溝部90に飲み込まれて保持される。すなわち、下框41bは、枠外側見込み面の室外側端部から垂下された室外側突出片92aと、室内側端部から垂下された室内側突出片92bとを有する。溝部90は、室外側突出片92aの室外側で対向する室外側壁部90aと、室内側突出片92bの室内側で対向する室内側壁部90bとを有する。図14中の参照符号94は、タイト材である。これにより内障子30は、火災時には突出片92a,92bが壁部90a,90bで保持されることで室内外への脱落や移動が抑制される。 First, as shown in FIG. 14, when the inner shoji 30 is closed, the lower part of the lower stile 41b of the frame body 41 is swallowed by the groove 90 of the lower frame 28b of the window frame 28 and held. That is, the lower stile 41b has an outdoor side projecting piece 92a hanging down from the outdoor side end of the frame outside prospective surface, and an indoor side projecting piece 92b hanging down from the indoor side end. The groove portion 90 has an outdoor side wall portion 90a that faces the outdoor side projecting piece 92a on the outdoor side, and an indoor side wall portion 90b that faces the indoor side projecting piece 92b on the indoor side. Reference numeral 94 in FIG. 14 is a tight material. As a result, in the event of a fire, the protruding pieces 92a, 92b of the inner shoji 30 are held by the walls 90a, 90b, thereby preventing the interior shoji 30 from falling off or moving indoors or outdoors.

ところが、下枠28bの金属下枠33b及びこれと一体に形成された戸体框20の金属下框21bは、アルミニウム合金で形成されているため、火災時に軟化する可能性がある。これら金属下枠33b及び金属下框21bは、軟化した状態で内障子30の重量を受けると変形し、内障子30の窓枠28からの脱落や下降を生じる懸念がある。 However, since the metal lower frame 33b of the lower frame 28b and the metal lower frame 21b of the door frame 20 formed integrally therewith are formed of an aluminum alloy, there is a possibility that they will soften in the event of a fire. These metal lower frame 33b and metal lower stile 21b will deform if they receive the weight of the inner shoji 30 in a softened state, and there is a concern that the inner shoji 30 may fall off or descend from the window frame 28.

そこで、本実施形態の建具10は、金属下枠33bの室外側壁部90aの室内側面に保持金具96を設けた構成としてもよい。保持金具96は、ステンレスやスチール等の金属板を略クランク形状に屈曲させたものである。保持金具96は、ねじ孔を有し、室外側壁部90aを貫通したねじ98を用いて室外側壁部90aに締結される。保持金具96は、上向きに屈曲した略L字状の保持片96aが内障子30の室外側突出片92aを受け止めるように設置される。これにより内障子30は、室外側突出片92aが保持金具96で保持されるため、火災時に金属下枠33bが軟化した場合にも、その転落や下降が抑制される。 Therefore, the fitting 10 of this embodiment may have a structure in which a holding fitting 96 is provided on the indoor side surface of the outdoor side wall portion 90a of the metal lower frame 33b. The holding fitting 96 is a metal plate made of stainless steel or steel bent into a substantially crank shape. The holding fitting 96 has a screw hole and is fastened to the outdoor wall 90a using a screw 98 that passes through the outdoor wall 90a. The holding fitting 96 is installed so that an upwardly bent substantially L-shaped holding piece 96a receives the outdoor side projecting piece 92a of the inner shoji 30. As a result, in the interior shoji 30, since the outdoor side projecting piece 92a is held by the holding fitting 96, even if the metal lower frame 33b becomes soft in the event of a fire, it is prevented from falling or descending.

次に、図14~図16に示すように、戸体框20の金属下框21bは、溝部90との間の仕切り壁100を挟んで隣接する中空部102を有する。中空部102には、ステンレスやスチール等の金属製の補強材104が配置されている。なお、図15では仕切り壁100の図示を省略している。 Next, as shown in FIGS. 14 to 16, the metal lower stile 21b of the door stile 20 has a hollow portion 102 adjacent to the groove portion 90 with a partition wall 100 interposed therebetween. A reinforcing material 104 made of metal such as stainless steel or steel is arranged in the hollow portion 102 . Note that in FIG. 15, illustration of the partition wall 100 is omitted.

補強材104は、金属下框21bの室外側見付け面を形成する室外側壁部21b1の内面に沿って起立する縦板104aと、縦板104aの上部から室内側に突出した上板104bと、縦板104aの下部から室内側に突出した下板104cとを有する構成としてもよい。縦板104a及び上板104bは、金属下框21bの長手方向の略全長に亘って延在している。下板104cは、室外側壁部21b1の下部に形成された左右の排水口21b2とオーバーラップする位置にそれぞれ設けられている。なお、図16では室外側壁部21b1の図示を省略している。 The reinforcing material 104 includes a vertical plate 104a that stands up along the inner surface of the outdoor side wall portion 21b1 that forms the outdoor side facing surface of the metal lower stile 21b, an upper plate 104b that protrudes from the top of the vertical plate 104a toward the indoor side, and A configuration may also be adopted in which a lower plate 104c protrudes toward the indoor side from the lower part of the plate 104a. The vertical plate 104a and the upper plate 104b extend over substantially the entire length of the metal lower frame 21b in the longitudinal direction. The lower plate 104c is provided at a position overlapping the left and right drain ports 21b2 formed at the lower part of the outdoor side wall portion 21b1. Note that in FIG. 16, illustration of the outdoor side wall portion 21b1 is omitted.

補強材104の縦板104a及び上板104bは、金属下框21bの仕切り壁100の下面に形成されたビスホール108を包含するように設けられている(図14参照)。上板104bの左右両端部から中央側に多少オフセットした位置には、ビスホール108の室内側で起立する起立片104dが設けられている。ビスホール108は、金属下框21bと金属吊元框21c及び金属戸先框21dとを締結するねじが螺合される部分である。 The vertical plate 104a and the upper plate 104b of the reinforcing member 104 are provided so as to encompass the screw holes 108 formed on the lower surface of the partition wall 100 of the metal lower stile 21b (see FIG. 14). Upright pieces 104d that stand up on the indoor side of the screw holes 108 are provided at positions slightly offset toward the center from both left and right ends of the upper plate 104b. The screw hole 108 is a portion into which a screw that fastens the metal lower stile 21b, the metal hanging stile 21c, and the metal door frame 21d is screwed together.

排水口21b2は、中空部102内に流入した雨水等を排水するものである。排水口21b2には、排水弁106が装着されている。仕切り壁100には、左右一対の排水孔100aが形成されている。補強材104の上板104bは、左右の排水孔100aからX方向に位置ずれした位置にそれぞれ切欠穴104eが設けられている(図15参照)。従って、建具10は、障子29,30の表面を流れて溝部90で受け止められた雨水等が排水孔100aを通して中空部102内に流入し、切欠穴104eを通過した後、下板104cの側部を通過して排水口21b2へと円滑に排水される。 The drain port 21b2 is for draining rainwater or the like that has flowed into the hollow portion 102. A drain valve 106 is attached to the drain port 21b2. A pair of left and right drainage holes 100a are formed in the partition wall 100. The upper plate 104b of the reinforcing member 104 is provided with cutout holes 104e at positions shifted in the X direction from the left and right drainage holes 100a (see FIG. 15). Therefore, in the fittings 10, rainwater, etc. that flowed on the surface of the shoji 29, 30 and were caught in the groove 90 flows into the hollow part 102 through the drainage hole 100a, passes through the notch hole 104e, and then flows into the side of the lower plate 104c. The water is smoothly drained through the drain port 21b2.

このように、戸体框20は、通風ユニット16の重量を受ける金属下框21bと、左右の金属吊元框21c及び金属戸先框21dとを締結するねじが固定されるビスホール108を補強材104で囲んでいる。このため、例えば火災時に、排水口21b2から中空部102内に火炎が侵入した場合であっても、補強材104でビスホール108が遮熱保護される。その結果、建具10は、火災時に金属下框21bと左右の金属吊元框21c及び金属戸先框21dとが分離することを抑制できる。また、補強材104の縦板104aは、中空部102の上下方向の略全高に亘って延在しているため、金属下框21bの潰れ自体も抑制できる。 In this way, the door frame 20 has reinforcing screw holes 108 to which screws are fixed for fastening the metal lower frame 21b that receives the weight of the ventilation unit 16, the left and right metal hanging frames 21c, and the metal door frame 21d. It is surrounded by 104. Therefore, even if flames enter the hollow portion 102 from the drain port 21b2 in the event of a fire, for example, the reinforcing material 104 protects the screw hole 108 from heat. As a result, the fittings 10 can suppress separation of the metal lower stile 21b, the left and right metal hanging frames 21c, and the metal door frame 21d in the event of a fire. Further, since the vertical plate 104a of the reinforcing member 104 extends over substantially the entire vertical height of the hollow portion 102, collapse of the metal lower stile 21b itself can be suppressed.

次に、図14~図16に示すように、補強材104及びその周辺部には、熱膨張性部材110,111,112,113,114,115を設けた構成としてもよい。熱膨張性部材110~115は、例えば加熱されると発泡して膨張する黒鉛等の加熱発泡材である。 Next, as shown in FIGS. 14 to 16, thermally expandable members 110, 111, 112, 113, 114, and 115 may be provided on the reinforcing member 104 and its surrounding area. The thermally expandable members 110 to 115 are, for example, heat foaming materials such as graphite that foam and expand when heated.

熱膨張性部材110は、補強材104の上板104bの上面において、排水孔100aとオーバーラップする位置に粘着固定されている。熱膨張性部材111は、仕切り壁100の上面において、排水孔100aの近傍に粘着固定されている。熱膨張性部材112は、補強材104の上板104bの上面における室外側端部に設けられ、熱膨張性部材110と見込み方向に並んでいる。熱膨張性部材113は、補強材104の縦板104aの室内側表面において、X方向で両端にそれぞれ粘着固定され、Y方向に延在している。熱膨張性部材114は、補強材104の下板104cの下面において、排水口21b2とオーバーラップする位置に粘着固定されている。熱膨張性部材115は、金属下框21bの枠外側見込み面に粘着固定され、金属下框21bの略全長に亘って延在している。 The thermally expandable member 110 is adhesively fixed to the upper surface of the upper plate 104b of the reinforcing member 104 at a position overlapping the drainage hole 100a. The thermally expandable member 111 is adhesively fixed on the upper surface of the partition wall 100 near the drainage hole 100a. The thermally expandable member 112 is provided at the outdoor end of the upper surface of the upper plate 104b of the reinforcing member 104, and is lined up with the thermally expandable member 110 in the viewing direction. Thermal expandable members 113 are adhesively fixed to both ends of the vertical plate 104a of the reinforcing member 104 at both ends in the X direction, and extend in the Y direction. The thermally expandable member 114 is adhesively fixed to the lower surface of the lower plate 104c of the reinforcing member 104 at a position overlapping the drain port 21b2. The thermally expandable member 115 is adhesively fixed to the outer side of the frame of the metal lower stile 21b, and extends over substantially the entire length of the metal lower stile 21b.

このように、戸体框20の金属下框21bは、外部に連通する排水口21b2の直上にある下板104cに熱膨張性部材114を設け、中空部102から溝部90に連通する排水孔102aの直下にある上板104bに熱膨張性部材110を設けている。このため、建具10は、火災時に排水口21b2から中空部102を通して溝部90へと連続する火炎や煙の貫通孔が形成されることを抑制できる。 In this way, the metal lower stile 21b of the door frame 20 is provided with a thermally expandable member 114 on the lower plate 104c located directly above the drain port 21b2 that communicates with the outside, and the drain hole 102a that communicates from the hollow portion 102 to the groove portion 90. A thermally expandable member 110 is provided on the upper plate 104b directly below the upper plate 104b. For this reason, the fittings 10 can suppress the formation of a through-hole for flames and smoke that continues from the drain port 21b2 through the hollow part 102 to the groove part 90 in the event of a fire.

建具10は、これら熱膨張性部材110~115以外にも、各所に熱膨張性部材が設けてもよい。そこで、熱膨張性部材110~115以外の熱膨張性部材については、図1~図3及び図14中で参照符号116を付して示している。なお、図14~図16中の参照符号118は、仕切り壁100(金属下框21b)に上板104bを締結するねじである。 In addition to these thermally expandable members 110 to 115, the fittings 10 may be provided with thermally expandable members at various locations. Therefore, thermally expandable members other than the thermally expandable members 110 to 115 are indicated with reference numeral 116 in FIGS. 1 to 3 and 14. Note that reference numeral 118 in FIGS. 14 to 16 is a screw that fastens the upper plate 104b to the partition wall 100 (metal lower frame 21b).

3.建具の一態様の説明
本発明の一態様に係る建具は、窓枠と、前記窓枠にスライド可能に支持され、閉鎖時に前記窓枠の室内側に配置される第1障子と、前記窓枠にスライド可能に支持され、閉鎖時に前記窓枠の室外側に配置される第2障子と、前記第1障子に取り付けられた金属製のクレセントと、前記第2障子の召合せ框に取り付けられ、前記クレセントが係合される金属製のクレセント受けと、を備え、前記第2障子の前記召合せ框は、面材の縁部を保持する開口溝と、前記開口溝に配置され、当該召合せ框の長手方向に沿って延在する金属製の開口溝補強材と、前記第2障子のスライド方向に対する前記クレセント受けと前記開口溝補強材との相対移動を規制する規制部材と、を有する。このような構成によれば、規制部材がクレセント受けと開口溝補強材との相対移動を規制するため、火災時にクレセント受けを介して開口溝補強材を支持することができる。これにより建具は、火災時に熱の影響を受け易い第2障子やその面材の移動や位置ずれを抑制して第2障子と窓枠との間に隙間が形成されることを抑制できるため、防火性能が向上する。
3. Description of one aspect of fittings A fitting according to one aspect of the present invention includes a window frame, a first shoji that is slidably supported by the window frame and is placed on the indoor side of the window frame when closed, and the window frame. a second shoji slidably supported by the window frame and disposed on the outdoor side of the window frame when closed, a metal crescent attached to the first shoji, and attached to a matching stile of the second shoji, a metal crescent holder with which the crescent is engaged; the joining stile of the second shoji has an opening groove that holds an edge of the panel; It has a metal opening groove reinforcing member extending along the longitudinal direction of the stile, and a regulating member regulating relative movement of the crescent receiver and the opening groove reinforcing member in the sliding direction of the second shoji. According to such a configuration, since the regulating member restricts relative movement between the crescent receiver and the opening groove reinforcing member, the opening groove reinforcing member can be supported via the crescent receiver in the event of a fire. As a result, the fittings can suppress the movement and displacement of the second shoji and its facing materials, which are easily affected by heat in the event of a fire, and prevent the formation of a gap between the second shoji and the window frame. Fire protection performance is improved.

前記規制部材は、前記クレセント受けを前記召合せ框に対して固定するねじで構成としてもよい。そうすると、建具は、クレセント受けを召合せ框に固定するねじを規制部材として兼用でき、部品点数やコストを低減できる。 The regulating member may be configured with a screw that fixes the crescent receiver to the joining frame. Then, in the fittings, the screws that fix the crescent receiver to the stile can also be used as regulating members, and the number of parts and cost can be reduced.

前記召合せ框は、前記開口溝の室内側壁部に形成され、前記ねじを挿通可能な孔部を有し、前記クレセント受けは、前記ねじが螺合されるねじ孔を有し、前記開口溝補強材は、前記ねじを挿入可能な規制穴を有し、前記ねじは、前記孔部に挿通された状態で前記ねじ孔に螺合されると共に、該ねじ孔を挿通した先端部が前記規制穴に挿入され、係止された構成としてもよい。そうすると、建具は、簡素な構成でクレセント受けと開口溝補強材との相対移動を規制することができる。 The matching stile is formed in the indoor side wall of the opening groove and has a hole through which the screw can be inserted, and the crescent receiver has a screw hole into which the screw is screwed, The reinforcing material has a regulation hole into which the screw can be inserted, and the screw is threaded into the screw hole while being inserted into the hole, and the tip of the screw inserted through the screw hole is inserted into the regulation hole. It may be inserted into a hole and locked. Then, the fitting can restrict relative movement between the crescent receiver and the opening groove reinforcing material with a simple configuration.

前記召合せ框の前記室内側壁部は、前記孔部とは異なる位置に設けられた第2孔部をさらに有し、前記開口溝補強材は、前記ねじとは別の第2ねじが螺合される第2ねじ孔をさらに有し、前記第2ねじは、前記第2孔部に挿通された状態で前記第2ねじ孔に螺合された構成としてもよい。そうすると、建具は、火災時に開口溝補強材が室外側に移動することを抑制でき、規制穴からのねじの脱落を抑制できる。 The indoor side wall of the joining stile further has a second hole provided at a position different from the hole, and the opening groove reinforcing material is screwed with a second screw different from the screw. The device may further include a second screw hole, and the second screw may be screwed into the second screw hole while being inserted into the second hole. In this way, the fittings can prevent the opening groove reinforcing material from moving toward the outdoor side in the event of a fire, and can prevent screws from falling out of the regulation holes.

前記召合せ框は、前記開口溝の室内側壁部に形成され、前記ねじを挿通可能な孔部を有し、前記クレセント受けは、前記ねじを挿通可能な挿通孔を有し、前記開口溝補強材は、前記ねじを挿通可能な規制穴を有し、さらに、前記ねじが螺合されるねじ孔が設けられた裏板を備え、前記ねじは、前記孔部、前記挿通孔、及び前記規制穴に順に挿通された状態で前記ねじ孔に螺合された構成としてもよい。そうすると、建具は、簡素な構成でクレセント受けと開口溝補強材との相対移動を規制することができる。 The joining frame is formed on the indoor side wall of the opening groove and has a hole through which the screw can be inserted, and the crescent receiver has an insertion hole through which the screw can be inserted, and the opening groove reinforcement The material has a regulation hole through which the screw can be inserted, and further includes a back plate provided with a screw hole into which the screw is screwed, and the screw is inserted into the hole, the insertion hole, and the regulation hole. It is also possible to have a structure in which the parts are sequentially inserted into the holes and then screwed into the screw holes. Then, the fitting can restrict relative movement between the crescent receiver and the opening groove reinforcing material with a simple configuration.

前記第1障子は、閉鎖時に前記窓枠の下部室内側に配置される内障子であり、前記第2障子は、閉鎖時に前記窓枠の上部室外側に配置される外障子であり、前記召合せ框は、前記外障子の下框である構成としてもよい。そうすると、建具は、火災時に特に熱の影響を受け易い外障子の脱落や下降を抑制できる。 The first shoji is an inner shoji that is placed on the lower indoor side of the window frame when closed, and the second shoji is an outer shoji that is placed on the upper indoor side of the window frame when closed. The laminated stile may be a lower stile of the outer shoji. In this way, the fittings can prevent the external shoji screens, which are particularly susceptible to the effects of heat, from falling off or falling in the event of a fire.

戸体をさらに備え、前記窓枠は、前記戸体に取り付けられた通風ユニットを構成する構成としてもよい。この場合、通風ユニットは、建物躯体に固定された開口枠ではなく、この開口枠に支持された戸体の戸体框に支持された構成となる。このため、建具は、室外側に配置される第2障子が火災時に一層脱落し易くなるが、これを規制部材による防火構造によって効果的に抑制できる。 The window frame may further include a door body, and the window frame may constitute a ventilation unit attached to the door body. In this case, the ventilation unit is supported not by the opening frame fixed to the building frame but by the door frame of the door body supported by the opening frame. For this reason, the second shoji door placed on the outside of the fittings becomes more likely to fall off in the event of a fire, but this can be effectively suppressed by the fire prevention structure using the regulating member.

なお、本発明は、上記した実施形態に限定されるものではなく、本発明の主旨を逸脱しない範囲で自由に変更できることは勿論である。 Note that the present invention is not limited to the embodiments described above, and it goes without saying that changes can be made freely without departing from the spirit of the present invention.

上記では、通風ユニット16の窓種として上げ下げ窓を例示したが、引違い窓等でもよい。この場合、外障子29と内障子30とは例えば左右に並んで引違い可能に設けられるとよい。 In the above example, a vertical window was exemplified as the window type of the ventilation unit 16, but a sliding window or the like may be used. In this case, it is preferable that the outer shoji 29 and the inner shoji 30 are arranged side by side in a reversible manner, for example.
