Description

本発明は、建具に関し、とくに防火性能を向上させた建具に関する。   The present invention relates to a joinery, and more particularly to a joinery having improved fire performance.

建具では、一般的に、障子の取り付けや取り外し又は開閉を容易にするために、建具枠の上内側面と障子の上外側面との間、建具枠の下内側面と障子の下外側面との間に隙間を設けている。
そのため、火災等でその框の一部が溶融、軟化すると伸びる。縦框が伸びると建具枠の下内側面と障子の下外側面との間隙間分だけ障子が自重で垂れ下がる。また、これに伴い、障子の上外側面と建具枠の上内側面との間の隙間が拡がり、火炎や熱風が通る貫通路（又は貫通孔）が生成され、防火上好ましくない。
この問題に対する解決策として、例えば、特許文献１には、火災等の熱により障子の反りや下がりを防止できるようにしたすべり出し窓が記載されている。
そこで、まず、特許文献１に記載されたすべり出し窓について説明する。 In joinery, in general, in order to facilitate the installation, removal, or opening / closing of shoji, it is between the upper inner surface of the joinery frame and the upper and outer surfaces of the shoji, the lower inner surface of the joinery frame, and the lower outer surface of the shoji. There is a gap between them.
Therefore, it expands when a part of the soot melts and softens due to a fire or the like. When the vertical eaves stretch, the shoji hangs under its own weight by the gap between the lower inner surface of the joinery frame and the lower outer surface of the shoji. Further, along with this, a gap between the upper outer surface of the shoji and the upper inner surface of the joinery frame is expanded, and a through passage (or a through hole) through which a flame or hot air passes is generated, which is not preferable in terms of fire prevention.
As a solution to this problem, for example, Patent Document 1 describes a sliding window that can prevent the shoji from warping or falling due to heat from a fire or the like.
First, the sliding window described in Patent Document 1 will be described.

図６は、特許文献１に記載されたすべり出し窓の障子の下部と下枠とを示す縦断面図である。
特許文献１に記載されたすべり出し窓７は、枠８に対して障子９をすべり出し自在に支持し、障子縦框７１の見込み面７１ａに設けた係止部材７５と、障子縦框７１に対向する位置で下枠６１の上面に設けた受け７７とを備えている。係止部材７５は、対向する縦枠側に突出した見付け壁７５ｂを有し、受け７７は、上方に突出した見込み壁７７ｂを有し、係止部材７５の見付け壁７５ｂは受け７７の見込み壁７７ｂよりも室内側で且つ上方に位置している。
火災発生時に障子縦框７１が熱により伸びると、係止部材７５の見付け壁７５ｂが、受け７７の見込み壁７７ｂの室内側に係止するか又は受け７７の見込み壁７７ｂの上端に当接支持（載置）される。
つまり、火災発生時に、係止部材７５を受け７７上に当接するか、又はその室内側に当接することで障子の反りや下がりを防止し、火災の噴出を防止している。 FIG. 6 is a longitudinal cross-sectional view showing a lower part and a lower frame of the sliding door of the sliding window described in Patent Document 1. As shown in FIG.
The sliding window 7 described in Patent Document 1 supports the shoji 9 so as to be able to slide out with respect to the frame 8, and faces the locking member 75 provided on the prospective surface 71 a of the shoji vertical spat 71 and the shoji vertical spatula 71. And a receiver 77 provided on the upper surface of the lower frame 61 at a position. The locking member 75 has a finding wall 75 b that protrudes to the opposite vertical frame side, the receiver 77 has a prospective wall 77 b that projects upward, and the finding wall 75 b of the latching member 75 is a prospective wall of the receiver 77. It is located indoors and above 77b.
When the shoji downboard 71 is extended by heat when a fire occurs, the finding wall 75b of the locking member 75 is locked to the indoor side of the prospective wall 77b of the receiver 77 or abutted and supported on the upper end of the prospective wall 77b of the receiver 77 (Mounted).
In other words, when a fire occurs, the locking member 75 is abutted on the receiving 77 or abutted on the indoor side thereof, thereby preventing warping and lowering of the shoji and preventing the fire from being ejected.

特許文献１に記載されたすべり出し窓は、火災等の熱による障子の下がりを防止することができる。しかし、その作用は、係止部材が設けられた下枠に対向する障子縦框近傍に限定されており、特に、窓形状が横に長いすべり出し窓の場合は、障子の下框が長くなるにつれて垂れ下がり量が増加するが、その下框の中央部における垂れ下がりについては全く考慮されていない。したがって、下框の長さが長くなるにつれて問題になる、下框の中央部の垂れ下がりを防止することはできない。
障子の中央部において垂れ下がりが生じると、結局、障子の反りにより障子と枠との間を貫通する隙間（以下、単に貫通孔という）が発生し、この貫通孔から熱風の流入や流出、火災の伝搬が発生することとなる。 The sliding window described in Patent Document 1 can prevent the shoji from falling due to heat such as a fire. However, its action is limited to the vicinity of the shoji vertical shaft facing the lower frame provided with the locking member. Especially, in the case of a sliding window with a long window shape, the lower armpit of the shoji becomes longer. Although the amount of sag increases, the sag at the center of the lower eyelid is not considered at all. Therefore, it is impossible to prevent the drooping of the center part of the lower eyelid which becomes a problem as the length of the lower eyelid becomes longer.
When the paper sag hangs down at the center of the shoji, a warp of the shoji will eventually cause a gap that passes between the shoji and the frame (hereinafter simply referred to as a through-hole). Propagation will occur.

以下、本発明の建具１の実施形態としてすべり出し窓を例に採り、図面を参照して説明する。
図１は、本発明の実施形態に係る建具１（即ち、すべり出し窓１）の正面図である。
すべり出し窓１は、図１に示すように、障子３と、枠体５とを備え、障子３は、枠体５に対して図示しないアームによりすべり出し可能（開閉自在）に支持される。 Hereinafter, a sliding window will be taken as an example of the embodiment of the fitting 1 of the present invention and will be described with reference to the drawings.
FIG. 1 is a front view of a joinery 1 (that is, a sliding window 1) according to an embodiment of the present invention.
As shown in FIG. 1, the sliding window 1 includes a shoji 3 and a frame 5, and the shoji 3 is supported by an arm (not shown) so as to be able to slide out (openable and closable) with respect to the frame 5.

枠体５は、上枠５ａ、下枠５ｂ及び左右の縦枠５ｃ、５ｄを枠組みして方形状に形成された開口枠である。
障子３は、上框３１ａと下框３１ｂ（総称して横框ともいう）、及び左右の縦框３１ｃ、３１ｄをガラスパネル３２の四周に框組することで構成される。
なお、下框３１ｂには、その長手方向中央部の下面において、火災等の熱で障子３が垂れ下がったとき、下框３１ｂを支持するための支持金具３３が設けられている。また、上框３１ａの中央部には引寄せ金具３４を設け、さらに上枠５ａには引寄せ金具３４と対向してガイドローラ５１が取り付けられている。 The frame 5 is an open frame formed in a square shape by framing the upper frame 5a, the lower frame 5b, and the left and right vertical frames 5c, 5d.
The shoji 3 is configured by assembling an upper eave 31a and a lower eave 31b (also collectively referred to as a horizontal eave), and left and right vertical eaves 31c and 31d around the glass panel 32.
In addition, the lower rod 31b is provided with a support metal 33 for supporting the lower rod 31b when the shoji 3 hangs down due to heat such as fire on the lower surface of the central portion in the longitudinal direction. Further, a pulling metal fitting 34 is provided at the center of the upper collar 31a, and a guide roller 51 is attached to the upper frame 5a so as to face the pulling metal fitting 34.

図２は、本発明の実施形態に係るすべり出し窓１の縦断面図であり、また図３は、本発明の実施形態に係るすべり出し窓１の横断面図である。
上框３１ａのガラスパネル収容凹部側には、図２に示すように、断面が略コの字形状の鋼材製の補強材３５が設けられている。また、上框３１ａの上面には、断面がＬ字型の補強金具３６が設けられている。
上框３１ａを補強材３５、補強金具３６により補強することで、上框３１ａが例えば火災等において弓なりに変形することを防止している。
なお、すべり出し窓１に関して、炎や熱風を遮断してその防火性能を高めるために、補強材３５の上述の凹部の底面室内側には加熱発泡材３７、また補強金具３６の室外面の室内側には加熱発泡材３８を設けている。 FIG. 2 is a longitudinal sectional view of the sliding window 1 according to the embodiment of the present invention, and FIG. 3 is a transverse sectional view of the sliding window 1 according to the embodiment of the present invention.
As shown in FIG. 2, a steel reinforcing member 35 having a substantially U-shaped cross section is provided on the upper panel 31 a on the glass panel housing recess side. In addition, a reinforcing metal fitting 36 having an L-shaped cross section is provided on the upper surface of the upper collar 31a.
The upper collar 31a is reinforced by the reinforcing member 35 and the reinforcing bracket 36 to prevent the upper collar 31a from being deformed like a bow in a fire or the like.
In addition, with respect to the sliding window 1, in order to block the flame and hot air and enhance the fireproof performance, the heating foam 37 and the indoor side of the outdoor surface of the reinforcing bracket 36 are provided on the inside of the bottom surface of the above-mentioned recess of the reinforcing material 35. Is provided with a heating foam material 38.

上框３１ａの上面には、その見付け方向、中央付近において、図２に示すように、引寄せ金具３４が、室内側に向かって上向きの傾斜面を形成するように取り付けられている。
なお、引寄せ金具３４は、耐火性を有する材料、例えば、鋼製金具等により形成される。
引寄せ金具３４は、障子３を開き位置から閉じ位置（閉鎖位置）に向けて移動したときに、上枠５ａに取り付けられる耐火性を有する鋼材製のガイドローラ５１に接して、障子３の吊元側である上框３１ａを室内側に引き寄せるガイド手段として機能する例えば傾斜した板体である。 As shown in FIG. 2, the attracting metal fitting 34 is attached to the upper surface of the upper collar 31 a so as to form an inclined surface upward toward the indoor side, as shown in FIG.
The attracting metal fitting 34 is formed of a fire-resistant material, for example, a steel metal fitting.
When the shoji 3 is moved from the open position toward the closed position (closed position), the pulling metal fitting 34 comes into contact with the fire-resistant steel-made guide roller 51 attached to the upper frame 5a and suspends the shoji 3. For example, it is an inclined plate that functions as a guide means for pulling the upper side 31a, which is the original side, toward the indoor side.

下框３１ｂのホロー部（中空部）内には、図２に示すように、断面が略コの字形状の補強金具３９が、ホロー部を構成する室内側壁面以外の壁面に当接配置されており、これにより、ガラスパネル３２の重量による下框３１ｂの潰れ、変形等を防止する。
また、下框３１ｂに取り付けられるカムラッチハンドル４０の裏板４１と断面が略コの字形状の鋼材製の補強材４２が、下框３１ｂの上述の凹部の上側壁面を介して、ビス４３等の固定部材で共締めされており、補強材４２の枠側との拘束を高めている。 In the hollow portion (hollow portion) of the lower rod 31b, as shown in FIG. 2, a reinforcing metal fitting 39 having a substantially U-shaped cross section is disposed in contact with a wall surface other than the indoor side wall surface constituting the hollow portion. This prevents the lower collar 31b from being crushed or deformed due to the weight of the glass panel 32.
Further, the back plate 41 of the cam latch handle 40 attached to the lower rod 31b and the steel reinforcing member 42 having a substantially U-shaped cross section are connected to the screw 43 and the like via the upper wall surface of the above-described recess of the lower rod 31b. The fixing member is fastened together to enhance the restraint with the frame side of the reinforcing member 42.

下框３１ｂの下枠５ｂの長手方向中央部に対向する部分には、その下面に、図２に示すように、障子３が、火災等の熱で熱変形し、中央部より垂れ下がってきたとき、下枠５ｂにより下框３１ｂを支持するための支持金具３３が設けられている。
なお、支持金具３３は、本発明の支持具に対応し、引寄せ金具３４と同様に、耐火性を有する材料、例えば、鋼製金具等により形成され、その外形などは、下框３１ｂを支持可能であれば任意である。また、下框３１ｂの上述の凹部の底面室外側には加熱発泡材４４が、また下框３１ｂの室外面延出部の内面側には加熱発泡材４５が貼り付けられている。 As shown in FIG. 2, the shoji 3 is thermally deformed by heat from a fire or the like and hangs down from the central portion on the lower surface of the lower frame 5 b facing the central portion in the longitudinal direction of the lower frame 31 b. A support fitting 33 for supporting the lower collar 31b by the lower frame 5b is provided.
The support metal fitting 33 corresponds to the support tool of the present invention, and is formed of a fire-resistant material, for example, a steel metal fitting, like the pulling metal fitting 34, and its outer shape supports the lower rod 31b. It is optional if possible. Further, the heating foam material 44 is attached to the outer side of the bottom surface of the above-mentioned recess of the lower collar 31b, and the heating foam material 45 is attached to the inner surface side of the outdoor surface extension part of the lower collar 31b.

図３に示すように、左右の縦框３１ｃ、３１ｄのホロー部枠体側底面には加熱発泡材４６、４７が、また縦框３１ｃ、３１ｄの室外面延出部の室内側には加熱発泡材４８、４９が固着されている。
さらに、左右の縦枠５ｃ、５ｄの下部において、火災時に発生するコーナー部の貫通孔を塞ぎ、炎や熱風の進入や排出を防ぐための加熱発泡材５２、５３が貼り付けられている。 As shown in FIG. 3, the heating foam materials 46 and 47 are provided on the bottom side of the hollow frame of the left and right vertical rods 31c and 31d, and the heating foam material is provided on the indoor side of the outdoor surface extending portion of the vertical rods 31c and 31d. 48 and 49 are fixed.
Furthermore, heating foam materials 52 and 53 are attached to the lower portions of the left and right vertical frames 5c and 5d to block the through-holes in the corner portions that are generated in the event of a fire and prevent the entry and discharge of flames and hot air.

図４は、本発明の実施形態に係るすべり出し窓１の障子３の下部と下枠５ｂとを示す縦断面図であり、図４Ａは、通常時、即ち、火災等が発生しておらず、障子３の中央部が垂れ下がっていない状態を、また図４Ｂは、火災等が発生し、その熱により、障子３の中央部が垂れ下がった状態を示している。
図４Ａに示すように、通常時には、下框３１ｂの下面に設けられた支持金具３３と下枠５ｂとは、所定の間隔を有するように形成されている。
そのため、支持金具３３は、通常時における、障子３の開閉動作（図４において、例えば、障子３のすべり出し動作等）において障害となることはない。 FIG. 4 is a longitudinal sectional view showing the lower part of the shoji 3 and the lower frame 5b of the sliding window 1 according to the embodiment of the present invention. FIG. 4A is a normal state, that is, no fire or the like has occurred. FIG. 4B shows a state in which the central portion of the shoji 3 is hung down, and FIG. 4B shows a state in which a fire or the like has occurred and the central portion of the shoji 3 has hung down due to the heat.
As shown in FIG. 4A, in normal times, the support fitting 33 provided on the lower surface of the lower collar 31b and the lower frame 5b are formed to have a predetermined interval.
Therefore, the support fitting 33 does not become an obstacle in the opening / closing operation of the shoji 3 at the normal time (for example, the sliding operation of the shoji 3 in FIG. 4).

火災等が発生し、障子３が熱変形し、中央部が垂れ下がると、図４Ｂに示すように、下框３１ｂの下面に設けられた支持金具３３が下枠５ｂの上面に当接し、障子３は支持金具３３により支持され、障子３のそれ以上の垂れ下がりが抑制される。
また、このように垂れ下がりを抑制することにより、框部材（框体３１）の変形を軽減し、上框３１ａからのガラスパネル３２の脱落を防止することができる。さらに、支持金具３３を設けることで、障子３の開き量も抑制されることから、貫通孔を塞ぐために貼り付ける加熱発泡材を削減することができる。 When a fire or the like occurs, the shoji 3 is thermally deformed, and the central portion hangs down, as shown in FIG. 4B, the support fitting 33 provided on the lower surface of the lower rod 31b comes into contact with the upper surface of the lower frame 5b, and the shoji 3 Is supported by the support fitting 33, and the further sag of the shoji 3 is suppressed.
Further, by suppressing the drooping in this way, deformation of the collar member (casing body 31) can be reduced, and the glass panel 32 can be prevented from falling off from the upper collar 31a. Furthermore, since the opening amount of the shoji 3 is also suppressed by providing the support fitting 33, it is possible to reduce the heating foam material that is stuck to close the through hole.

なお、図４に示す、すべり出し窓１では、支持金具３３を下框３１ｂの下面に設ける構造としているが、障子３が熱変形し、中央部が垂れ下がった場合に、障子３を支持し、その垂れ下がりを抑制することが可能であれば、支持金具３３を、下框３１ｂの長手方向中央部に対向する位置の下枠５ｂの上面に設ける構造としてもよい。   The sliding window 1 shown in FIG. 4 has a structure in which the support fitting 33 is provided on the lower surface of the lower rod 31b. However, when the shoji 3 is thermally deformed and the central portion hangs down, the shoji 3 is supported. If it is possible to suppress the drooping, the support fitting 33 may be provided on the upper surface of the lower frame 5b at a position facing the longitudinal center of the lower collar 31b.

図５は、本発明の実施形態に係るすべり出し窓１の障子３の上部と上枠５ａとを示す縦断面図である。
なお、図５は、図４Ｂに示した下框３１ｂに設けられた支持金具３３により障子３を支持した状態を示している。
図４Ｂに示すように、支持金具３３により障子３の垂れ下がりを抑制することで、引寄せ金具３４とガイドローラ５１が外れることを防止し、傾斜面を備えた引寄せ金具３４とガイドローラ５１を当接させ（干渉させ）、かつ障子３を室内側の上枠５ａ側に拘束することで、框体３１の倒れ、及び障子３の中央部の垂れ下がり、開き等を抑制している。
また、このような構造にすることで、貫通孔の発生も防止することができる。 FIG. 5 is a longitudinal sectional view showing the upper part of the shoji 3 and the upper frame 5a of the sliding window 1 according to the embodiment of the present invention.
FIG. 5 shows a state in which the shoji 3 is supported by the support fitting 33 provided on the lower rod 31b shown in FIG. 4B.
As shown in FIG. 4B, the support fitting 33 prevents the shoji 3 from sagging, thereby preventing the draw fitting 34 and the guide roller 51 from coming off, and the draw fitting 34 and the guide roller 51 having an inclined surface. By contacting (interfering) and restricting the shoji 3 to the upper frame 5a side on the indoor side, the fall of the casing 31 and the drooping and opening of the central portion of the shoji 3 are suppressed.
Moreover, generation | occurrence | production of a through-hole can be prevented by setting it as such a structure.

以上、説明したように、本発明の実施形態に係るすべり出し窓によれば、障子の下框の長手方向中央部の下面、又は障子の下枠の長手方向中央部に対向する位置の下枠の上面に、下枠により下框を支持するための支持金具を設けることで、火災等の熱による障子の中央部における垂れ下がりを抑制し、防火性能を向上させることができる。
また、本発明の実施形態に係るすべり出し窓によれば、火災等の熱による障子の垂れ下がりを支持金具により抑制して引寄せ金具とガイドローラを当接させ、引寄せ金具の傾斜面に沿って障子を窓枠側に引寄せ、拘束することで、障子の開きを抑制し、さらに貫通孔の発生を防止することができる。
なお、以上の実施形態では、すべり出し窓を例に採って説明したが、本発明はこれに限定されず、火災時において、横框の長手方向中央部が垂れ下がることが予測される建具、例えば、突き出し窓、外倒し窓、内倒し窓、開き窓にも適用可能である。 As described above, according to the sliding window according to the embodiment of the present invention, the bottom surface of the lower frame at the position opposite to the lower surface of the lower center of the shoji of the shoji or the longitudinal center of the lower frame of the shoji By providing a support bracket for supporting the lower lid with the lower frame on the upper surface, it is possible to suppress sagging in the central part of the shoji due to heat such as a fire and to improve fire prevention performance.
Further, according to the sliding window according to the embodiment of the present invention, the support metal fitting is used to suppress the hanging of the shoji due to heat such as a fire, and the drawing metal fitting and the guide roller are brought into contact with each other along the inclined surface of the drawing metal fitting. By pulling and restraining the shoji to the window frame side, it is possible to suppress the opening of the shoji and further prevent the generation of a through hole.
In the above embodiment, the sliding window has been described as an example, but the present invention is not limited to this, and in the event of a fire, a fitting that is predicted to hang down in the longitudinal direction in the longitudinal direction, for example, It can also be applied to a protruding window, an outside window, an inside window, and a casement window.
