Description

本発明は、建材に熱膨張性部材を保持するための保持部材及び保持部材によって建材に熱膨張性部材が保持された建具に関するものである。 The present invention relates to a holding member for holding a heat-expandable member in a building material and a fitting in which the heat-expandable member is held in the building material by the holding member.

防火性を考慮した建具では、枠や框、補強材等の建材に対して適宜箇所に熱膨張性部材が貼り付けてあり、高温状態となった場合に隙間を塞ぐことで、火炎の貫通口が生じる事態を防止するようにしている。この種の建具には、建材にネジ止めした保持部材によって熱膨張性部材の上面を押さえることにより、建材からの剥がれを防止するようにしたものも提供されている（例えば、特許文献１参照）。 In fittings that take fire protection into consideration, heat-expandable members are attached to building materials such as frames, stiles, and reinforcing materials at appropriate locations, and by closing the gaps when the temperature rises, the flame penetration port is opened. I try to prevent the situation that occurs. Some fittings of this type are provided in which the upper surface of the heat-expandable member is pressed by a holding member screwed to the building material to prevent peeling from the building material (see, for example, Patent Document 1). ..

特開２０１４−１０９０９２号公報Japanese Unexamined Patent Publication No. 2014-109092

ところで、熱膨張性部材は、建材のほぼ全長にわたって連続するように設けられている場合が多い。従って、建材からの剥がれを防止するためには、複数の保持部材が必要となる。このため、保持部材を取り付けるための作業が煩雑となるばかりか、予め建材にネジ孔を設けておく必要があり、製造作業及び製造コストの点で改善の余地がある。 By the way, the heat-expandable member is often provided so as to be continuous over almost the entire length of the building material. Therefore, in order to prevent peeling from the building material, a plurality of holding members are required. For this reason, not only the work for attaching the holding member becomes complicated, but also it is necessary to provide screw holes in the building material in advance, and there is room for improvement in terms of manufacturing work and manufacturing cost.

本発明は、上記実情に鑑みて、製造作業及び製造コストを改善することのできる保持部材及び建具を提供することを目的とする。 An object of the present invention is to provide a holding member and fittings capable of improving manufacturing work and manufacturing cost in view of the above circumstances.

上記目的を達成するため、本発明に係る保持部材は、弾性材料によって成形され、弾性復元力によって建材に装着された状態を維持するとともに、弾性復元力によって前記建材の取付表面に熱膨張性部材を押圧することを特徴とする。 In order to achieve the above object, the holding member according to the present invention is formed of an elastic material and is maintained in a state of being mounted on the building material by the elastic restoring force, and the heat-expandable member is attached to the mounting surface of the building material by the elastic restoring force. It is characterized by pressing.

また、本発明に係る建具は、建材の取付表面に熱膨張性部材が設けられる建具であって、弾性復元力によって前記建材に装着された状態を維持するとともに、弾性復元力によって前記建材の取付表面に前記熱膨張性部材を押圧する保持部材を備えたことを特徴とする。 Further, the fitting according to the present invention is a fitting in which a heat-expandable member is provided on the mounting surface of the building material, and the state of being mounted on the building material is maintained by the elastic restoring force, and the building material is mounted by the elastic restoring force. The surface is provided with a holding member that presses the heat-expandable member.

本発明によれば、保持部材の弾性復元力によって保持部材が建材に装着された状態を維持するとともに、熱膨張性部材が建材に押圧された状態となるため、ネジ等々、保持部材を建材に保持させるための部品が別に必要になることがなく、建材にネジ孔等の加工を施す必要もない。従って、製造作業を容易化することができるとともに、製造コストの削減を図ることが可能となる。 According to the present invention, the holding member is kept attached to the building material by the elastic restoring force of the holding member, and the heat-expandable member is pressed against the building material. Therefore, the holding member such as a screw is used as the building material. No separate parts for holding are required, and there is no need to process the building material such as screw holes. Therefore, the manufacturing work can be facilitated and the manufacturing cost can be reduced.

以下、添付図面を参照しながら本発明に係る保持部材及び建具の好適な実施の形態について詳細に説明する。
図１は、本発明の実施の形態である保持部材を適用した建具の要部を示したものである。ここで例示する建具は、枠体１０に対して室内側の内障子２０及び室外側の外障子３０をスライド可能に配設した引き違い窓と称されるものである。枠体１０は、図には明示していないが、上枠、下枠（建材）１１及び左右の縦枠１２を四周枠組みすることによって構成したものである。内障子２０及び外障子３０は、それぞれ矩形状を成すガラス等の面材２１，３１の四周にそれぞれ上框、下框２２，３２及び左右の縦框を装着することによって構成したものである。枠体１０の枠及び障子の框は、いずれもアルミニウム合金等の金属によって成形した押し出し形材であり、それぞれが長手に沿った全長にわたってほぼ一様な断面形状を有するように構成してある。 Hereinafter, preferred embodiments of the holding member and fittings according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows a main part of a fitting to which a holding member according to an embodiment of the present invention is applied. The fitting illustrated here is called a sliding window in which the indoor sash 20 and the outdoor sash 30 are slidably arranged with respect to the frame body 10. Although not clearly shown in the figure, the frame body 10 is configured by forming a four-circumferential framework of an upper frame, a lower frame (building material) 11, and left and right vertical frames 12. The inner sash 20 and the outer sash 30 are constructed by attaching upper stiles, lower stiles 22, 32 and left and right vertical stiles to the four circumferences of face materials 21 and 31 such as glass having a rectangular shape, respectively. The frame of the frame body 10 and the stile of the shoji are both extruded shapes formed of a metal such as an aluminum alloy, and each is configured to have a substantially uniform cross-sectional shape over the entire length along the longitudinal axis.

この引き違い窓には、下枠１１に２つのレール部４１，４２が設けてある。２つのレール部４１，４２は、それぞれ鉛直方向に沿って延在する平板状を成し、個々の上縁部が室内側に向けて凸となるように厚板状となったもので、互いに平行となるように見込み方向に並設してある。室内側の内レール部４１は、戸車２３を介して内障子２０をスライド可能に支持するものであり、室外側の外レール部（押圧受部）４２は、戸車３３を介して外障子３０をスライド可能に支持するものである。 In this sliding window, two rail portions 41 and 42 are provided on the lower frame 11. The two rail portions 41 and 42 each have a flat plate shape extending along the vertical direction, and each has a thick plate shape so that the upper edge portions are convex toward the indoor side. They are arranged side by side in the expected direction so that they are parallel. The inner rail portion 41 on the indoor side slidably supports the inner sash 20 via the door roller 23, and the outer rail portion (pressing receiving portion) 42 on the outdoor side supports the outer sash 30 via the door roller 33. It is a slideable support.

ここで、見込み方向とは、図中の矢印Ａで示すように、建具の奥行きに沿った方向である。つまり、図１においては紙面に沿った左右方向が見込み方向となる。見込み方向に沿った面については見込み面と称する場合がある。また、この実施の形態では見付け方向という用語も用いる。見付け方向は、下枠１１等のように水平方向に沿って延在するものの場合、見込み方向に直交した上下に沿う方向である。縦枠１２等のように上下方向に沿って延在するものの場合には、見込み方向に直交した水平に沿う方向を見付け方向という。見付け方向に沿った面については、見付け面と称する場合がある。 Here, the prospective direction is a direction along the depth of the fitting as shown by an arrow A in the drawing. That is, in FIG. 1, the left-right direction along the paper surface is the prospective direction. A surface along the prospective direction may be referred to as a prospective surface. The term finding direction is also used in this embodiment. The finding direction is a direction along the top and bottom orthogonal to the prospective direction in the case of a lower frame 11 or the like extending along the horizontal direction. In the case of a vertical frame 12 or the like extending along the vertical direction, the direction along the horizontal direction orthogonal to the prospective direction is called the finding direction. A surface along the finding direction may be referred to as a finding surface.

図１及び図２からも明らかなように、内レール部４１は、外レール部４２よりも突出高さが大きくなるように構成してあり、外レール部４２との間が湾曲凹状の連結壁部４３によって連結してある。連結壁部４３は、内レール部４１に沿って上下に延在する垂直延在部４３ａと、垂直延在部４３ａの下端から室外に向けて漸次下方となるように傾斜した傾斜延在部４３ｂと、傾斜延在部４３ｂの下端から室外に向けてほぼ水平に延在した水平延在部４３ｃとを有したものである。水平延在部４３ｃの延在縁部は、外レール部４２の下端に連結している。また、内レール部４１の下縁部には、気密材保持壁部（押圧受部）４４が設けてある。気密材保持壁部４４は、内レール部４１の室外に臨む見付け面４１ａから室外に向けてほぼ水平に延在した後、下方に向けてほぼ直角に屈曲したもので、室外に臨む部分に装着溝４４ａが形成してある。装着溝４４ａは、外障子３０の室内に臨む見付け面３０ａに当接するための気密材５０が装着されるものである。この連結壁部４３には、上方に位置する表面（取付表面）４３ｄに熱膨張性部材６０が配設してあるとともに、熱膨張性部材６０の表面複数箇所に保持部材７０が配設してある。 As is clear from FIGS. 1 and 2, the inner rail portion 41 is configured so that the protruding height is larger than that of the outer rail portion 42, and the connecting wall having a curved concave shape between the inner rail portion 41 and the outer rail portion 42. It is connected by a part 43. The connecting wall portion 43 has a vertical extending portion 43a extending vertically along the inner rail portion 41 and an inclined extending portion 43b inclined so as to gradually decrease downward from the lower end of the vertical extending portion 43a toward the outside of the room. And a horizontally extending portion 43c extending substantially horizontally from the lower end of the inclined extending portion 43b toward the outside of the room. The extending edge portion of the horizontal extending portion 43c is connected to the lower end of the outer rail portion 42. Further, an airtight material holding wall portion (press receiving portion) 44 is provided on the lower edge portion of the inner rail portion 41. The airtight material holding wall portion 44 extends substantially horizontally from the finding surface 41a facing the outside of the inner rail portion 41 toward the outside, and then bends at a substantially right angle downward, and is attached to the portion facing the outside. A groove 44a is formed. The mounting groove 44a is for mounting the airtight material 50 for contacting the finding surface 30a of the external shoji 30 facing the room. In the connecting wall portion 43, the heat-expandable member 60 is arranged on the surface (mounting surface) 43d located above, and the holding members 70 are arranged on a plurality of places on the surface of the heat-expandable member 60. be.

熱膨張性部材６０は、熱により膨張する不燃性または難燃性の耐火部材である。この種の熱膨張性部材６０としては、例えば熱膨張性を有した黒鉛含有の発泡材を適用することができる。本実施の形態では、図３に示すように、幅方向の寸法に対して板厚の薄い断面形状を有した長尺状の熱膨張性部材６０を適用し、下枠１１の適宜箇所に配設してある。図には明示していないが、熱膨張性部材６０は、下枠１１の全長に配設しても良いし、下枠１１の一部分にのみ配設しても良い。熱膨張性部材６０には、連結壁部４３の垂直延在部４３ａ、傾斜延在部４３ｂ及び水平延在部４３ｃのそれぞれに対して隙間なく配設することができるように、長手に沿った２つの折り曲げ線６１が設けてある。すなわち、熱膨張性部材６０には、２つの折り曲げ線６１を設けることにより、垂直延在部４３ａに対応して配設される第１平面膨張部６０ａと、傾斜延在部４３ｂに対応して配設される第２平面膨張部６０ｂと、水平延在部４３ｃに対応して配設される第３平面膨張部６０ｃとが設けてある。図には明示していないが、熱膨張性部材６０の３つの平面膨張部６０ａ，６０ｂ，６０ｃと連結壁部４３の表面４３ｄとの間には、それぞれ両面テープ等の接着手段が設けてある。 The heat-expandable member 60 is a nonflammable or flame-retardant refractory member that expands due to heat. As the heat-expandable member 60 of this type, for example, a graphite-containing foaming material having heat-expandability can be applied. In the present embodiment, as shown in FIG. 3, a long heat-expandable member 60 having a cross-sectional shape having a thin plate thickness with respect to the dimension in the width direction is applied and arranged at appropriate positions on the lower frame 11. It is set up. Although not explicitly shown in the figure, the heat-expandable member 60 may be arranged over the entire length of the lower frame 11 or may be arranged only on a part of the lower frame 11. The thermally expandable member 60 is provided along the longitudinal direction so that it can be arranged without a gap with respect to each of the vertically extending portion 43a, the inclined extending portion 43b, and the horizontally extending portion 43c of the connecting wall portion 43. Two bending lines 61 are provided. That is, by providing the thermally expandable member 60 with two bending lines 61, the first plane expansion portion 60a arranged corresponding to the vertically extending portion 43a and the inclined extending portion 43b are supported. A second plane expansion portion 60b to be arranged and a third plane expansion portion 60c to be arranged corresponding to the horizontally extending portion 43c are provided. Although not explicitly shown in the figure, adhesive means such as double-sided tape are provided between the three planar expansion portions 60a, 60b, 60c of the heat-expandable member 60 and the surface 43d of the connecting wall portion 43, respectively. ..

保持部材７０は、ステンレス鋼等の比較的弾性に富んだ金属の薄板によって成形したものである。本実施の形態では、図２〜図４に示すように、基板部７１と、基板部７１の両側端部に設けた２つの押圧片部７２，７３とを一体に成形した保持部材７０を適用している。この保持部材７０は、熱膨張性部材６０が外部に露出するように配設することが好ましい。また保持部材７０を設ける数は、熱膨張性部材６０の長さによって適宜選択すれば、１つであっても複数でも良い。 The holding member 70 is formed of a thin plate of a metal having a relatively high elasticity such as stainless steel. In the present embodiment, as shown in FIGS. 2 to 4, a holding member 70 is applied in which the substrate portion 71 and the two pressing piece portions 72, 73 provided at both side ends of the substrate portion 71 are integrally molded. doing. The holding member 70 is preferably arranged so that the heat-expandable member 60 is exposed to the outside. The number of holding members 70 to be provided may be one or a plurality as long as it is appropriately selected according to the length of the heat-expandable member 60.

基板部７１は、熱膨張性部材６０の表面に当接するもので、垂直当接部７１ａ、傾斜当接部７１ｂ、水平当接部７１ｃを有している。垂直当接部７１ａは、連結壁部４３の垂直延在部４３ａとの間に熱膨張性部材６０の第１平面膨張部６０ａを挟持するものである。同様に、傾斜当接部７１ｂは、連結壁部４３の傾斜延在部４３ｂとの間に熱膨張性部材６０の第２平面膨張部６０ｂを挟持するもので、水平当接部７１ｃは、連結壁部４３の水平延在部４３ｃとの間に熱膨張性部材６０の第３平面膨張部６０ｃを挟持するものである。これら垂直当接部７１ａ、傾斜当接部７１ｂ、水平当接部７１ｃは、下枠１１の長手に沿う方向の寸法（以下、保持部材７０においては幅方向と称する）が互いに同一となるように形成してある。図２（ｂ）からも明らかなように、垂直当接部７１ａと傾斜当接部７１ｂとの間は、外力が加えられていない場合（以下、常態にある場合という）、互いの屈曲角度が連結壁部４３における垂直延在部４３ａと傾斜延在部４３ｂとの屈曲角度よりもわずかに大きくなるように成形してある。傾斜当接部７１ｂと水平当接部７１ｃとの間においても、常態にある場合、互いの屈曲角度が連結壁部４３における傾斜延在部４３ｂと水平延在部４３ｃとの屈曲角度よりもわずかに大きくなるように成形してある。 The substrate portion 71 abuts on the surface of the heat-expandable member 60, and has a vertical abutting portion 71a, an inclined abutting portion 71b, and a horizontal abutting portion 71c. The vertical contact portion 71a sandwiches the first plane expansion portion 60a of the thermally expandable member 60 between the vertical contact portion 71a and the vertically extending portion 43a of the connecting wall portion 43. Similarly, the inclined contact portion 71b sandwiches the second plane expansion portion 60b of the thermally expandable member 60 between the inclined extension portion 43b of the connecting wall portion 43, and the horizontal contact portion 71c is connected. The third plane expansion portion 60c of the thermally expandable member 60 is sandwiched between the horizontally extending portion 43c of the wall portion 43. The vertical contact portion 71a, the inclined contact portion 71b, and the horizontal contact portion 71c have the same dimensions in the direction along the length of the lower frame 11 (hereinafter, referred to as the width direction in the holding member 70). It is formed. As is clear from FIG. 2B, when no external force is applied between the vertical contact portion 71a and the inclined contact portion 71b (hereinafter, referred to as a normal state), the bending angles of the vertical contact portion 71a and the inclined contact portion 71b are different from each other. It is molded so as to be slightly larger than the bending angle between the vertically extending portion 43a and the inclined extending portion 43b in the connecting wall portion 43. Even between the inclined contact portion 71b and the horizontal contact portion 71c, in the normal state, the bending angle of each other is slightly smaller than the bending angle of the inclined extending portion 43b and the horizontal extending portion 43c in the connecting wall portion 43. It is molded so that it becomes large.

第１の押圧片部７２は、水平当接部７１ｃの端部から一方の表面側に屈曲するように延在したもので、幅方向の寸法が水平当接部７１ｃとほぼ同一である。第１の押圧片部７２と水平当接部７１ｃとの間の互いの屈曲角度は、常態にある場合、水平延在部４３ｃと外レール部４２との挟角（９０°）よりも大きくなるように鈍角に構成してある。水平当接部７１ｃからの第１の押圧片部７２の突出寸法は、外レール部４２において水平延在部４３ｃから厚板となる部分までの距離よりも短くなるように構成してある。常態にある場合には、垂直当接部７１ａから第１の押圧片部７２の延在縁部までの見込み方向に沿った寸法が、垂直延在部４３ａから外レール部４２までの距離よりも大きい。 The first pressing piece portion 72 extends from the end portion of the horizontal contact portion 71c so as to bend toward one surface side, and its dimension in the width direction is substantially the same as that of the horizontal contact portion 71c. The bending angle between the first pressing piece portion 72 and the horizontal contact portion 71c is larger than the sandwiching angle (90 °) between the horizontally extending portion 43c and the outer rail portion 42 in the normal state. It is configured at an obtuse angle. The protruding dimension of the first pressing piece portion 72 from the horizontal contact portion 71c is configured to be shorter than the distance from the horizontally extending portion 43c to the portion to be a thick plate in the outer rail portion 42. In the normal state, the dimension along the prospective direction from the vertical contact portion 71a to the extending edge portion of the first pressing piece portion 72 is larger than the distance from the vertical extending portion 43a to the outer rail portion 42. big.

第２の押圧片部７３は、垂直当接部７１ａの端部から第１の押圧片部７２と同じ表面側に屈曲するように延在したもので、垂直当接部７１ａの両側から突出するように、幅方向の寸法が垂直当接部７１ａよりも大きく構成してある。第２の押圧片部７３と垂直当接部７１ａとの間の互いの屈曲角度は、常態にある場合、垂直延在部４３ａと気密材保持壁部４４との挟角とほぼ同じ９０°である。垂直当接部７１ａからの第２の押圧片部７３の突出寸法は、垂直延在部４３ａからの気密材保持壁部４４の突出寸法よりも短くなるように構成してある。この第２の押圧片部７３には、逃げ部（位置決め手段：切欠）７３ａが設けてあるとともに、垂直当接部７１ａから突出した部分にそれぞれ係止片部７３ｂが一体に設けてある。逃げ部７３ａは、第２の押圧片部７３の先端縁部において幅方向のほぼ中央となる部分に形成した湾曲凹状の切欠である。係止片部７３ｂは、第２の押圧片部７３において垂直当接部７１ａが延在する基端縁部から突出したもので、突出寸法及び幅方向の寸法がいずれも垂直当接部７１ａより短く構成してある。常態にある場合には、第２の押圧片部７３から水平当接部７１ｃの延在縁部までの距離が、気密材保持壁部４４から水平延在部４３ｃまでの距離よりも大きい。 The second pressing piece portion 73 extends from the end of the vertical contact portion 71a so as to bend toward the same surface side as the first pressing piece portion 72, and projects from both sides of the vertical contact portion 71a. As described above, the dimension in the width direction is larger than that of the vertical contact portion 71a. The bending angle between the second pressing piece portion 73 and the vertical contact portion 71a is 90 °, which is almost the same as the sandwiching angle between the vertical extending portion 43a and the airtight material holding wall portion 44 under the normal condition. be. The protruding dimension of the second pressing piece portion 73 from the vertical contact portion 71a is configured to be shorter than the protruding dimension of the airtight material holding wall portion 44 from the vertical extending portion 43a. The second pressing piece portion 73 is provided with a relief portion (positioning means: notch) 73a, and a locking piece portion 73b is integrally provided at a portion protruding from the vertical contact portion 71a. The relief portion 73a is a curved concave notch formed in a portion substantially central in the width direction at the tip edge portion of the second pressing piece portion 73. The locking piece portion 73b protrudes from the base end edge portion where the vertical contact portion 71a extends in the second pressing piece portion 73, and both the protruding dimension and the dimension in the width direction are from the vertical contact portion 71a. It is short. In the normal state, the distance from the second pressing piece portion 73 to the extending edge portion of the horizontal contact portion 71c is larger than the distance from the airtight material holding wall portion 44 to the horizontally extending portion 43c.

なお、保持部材７０における基板部７１、押圧片部７２，７３の連結部や基板部７１における垂直当接部７１ａ、傾斜当接部７１ｂ、水平当接部７１ｃの連結部は、折り目が付くように屈曲しても良いし、Ｒ曲げ等のように湾曲状に構成しても良い。 The connecting portion of the substrate portion 71 and the pressing piece portions 72 and 73 of the holding member 70, and the connecting portion of the vertical contact portion 71a, the inclined contact portion 71b, and the horizontal contact portion 71c of the substrate portion 71 should be creases. It may be bent into a curved shape such as R-bent.

一方、上述した熱膨張性部材６０には、保持部材７０を設けるべき位置に位置決め用目印６２及び係止切欠部６３が設けてある。位置決め用目印６２は、熱膨張性部材６０の第３平面膨張部６０ｃを一部切り欠くことによって構成してある。本実施の形態では、熱膨張性部材６０の端部に端部位置決め用目印６２Ａが設けてあり、熱膨張性部材６０の中間部に中間部位置決め用目印６２Ｂが設けてある。端部位置決め用目印６２Ａは、第３平面膨張部６０ｃの端部を矩形状に切り欠くことによって形成してある。この端部位置決め用目印６２Ａは、基板部７１によって覆われず、かつ下枠１１の短手に沿った切欠縁部６２ａに対して保持部材７０における基板部７１の縁部が合致されている場合に、熱膨張性部材６０に対して所望の位置に保持部材７０が位置決め配置されていることを示すものである。中間部位置決め用目印６２Ｂは、第３平面膨張部６０ｃの縁部を半円状に切り欠くことによって形成してある。半円の直径は、基板部７１の幅方向に沿った寸法よりも小さい。この中間部位置決め用目印６２Ｂは、基板部７１によってすべてが覆い隠された場合に、熱膨張性部材６０に対して所望の位置に保持部材７０が位置決め配置されていることを示すものである。 On the other hand, the above-mentioned thermal expansion member 60 is provided with a positioning mark 62 and a locking notch 63 at a position where the holding member 70 should be provided. The positioning mark 62 is configured by partially cutting out the third plane expansion portion 60c of the thermally expandable member 60. In the present embodiment, the end positioning mark 62A is provided at the end of the heat-expandable member 60, and the intermediate positioning mark 62B is provided at the middle of the heat-expandable member 60. The end positioning mark 62A is formed by cutting out the end of the third plane expansion portion 60c in a rectangular shape. When the end positioning mark 62A is not covered by the substrate portion 71 and the edge portion of the substrate portion 71 in the holding member 70 is aligned with the cutout edge portion 62a along the short side of the lower frame 11. It shows that the holding member 70 is positioned and arranged at a desired position with respect to the heat-expandable member 60. The intermediate portion positioning mark 62B is formed by cutting out the edge portion of the third plane expansion portion 60c in a semicircular shape. The diameter of the semicircle is smaller than the dimension along the width direction of the substrate portion 71. The intermediate portion positioning mark 62B indicates that the holding member 70 is positioned and arranged at a desired position with respect to the thermally expandable member 60 when all of the intermediate portion positioning mark 62B is covered by the substrate portion 71.

係止切欠部６３は、熱膨張性部材６０の第１平面膨張部６０ａを一部切り欠くことによって構成したもので、保持部材７０の係止片部７３ｂを収容することのできる大きさの矩形状に形成してある。この係止切欠部６３は、保持部材７０の係止片部７３ｂが配置された状態で熱膨張性部材６０に対して保持部材７０が移動した場合に係止片部７３ｂに係合することで相対移動を制限するように機能する。上述したように、保持部材７０には、２つの係止片部７３ｂが設けてあるが、係止切欠部６３はそれぞれの保持部材７０に対して一つだけ設けるようにしている。すなわち、図示の例のように、熱膨張性部材６０の端部においては、保持部材７０が位置決め配置された場合、一方の係止片部７３ｂが係止切欠部６３に配置される一方、もう一方の係止片部７３ｂが熱膨張性部材６０の外部に配置されるようにそれぞれの寸法が設定してある。熱膨張性部材６０の中間部においては、第２平面膨張部６０ｂからの第１平面膨張部６０ａの延在寸法を短縮することで一方の係止片部７３ｂのみが係止切欠部６３に収容されるように構成してある。 The locking notch 63 is formed by partially notching the first plane expansion portion 60a of the thermally expandable member 60, and is a rectangle having a size capable of accommodating the locking piece portion 73b of the holding member 70. It is formed in a shape. The locking notch 63 engages with the locking piece 73b when the holding member 70 moves with respect to the thermally expandable member 60 in a state where the locking piece 73b of the holding member 70 is arranged. It works to limit relative movement. As described above, the holding member 70 is provided with two locking piece portions 73b, but only one locking notch portion 63 is provided for each holding member 70. That is, as shown in the illustrated example, at the end of the heat-expandable member 60, when the holding member 70 is positioned and arranged, one locking piece portion 73b is arranged in the locking notch 63, while the other. Each dimension is set so that one locking piece portion 73b is arranged outside the thermally expandable member 60. In the intermediate portion of the thermally expandable member 60, by shortening the extending dimension of the first plane expansion portion 60a from the second plane expansion portion 60b, only one locking piece portion 73b is accommodated in the locking notch portion 63. It is configured to be done.

上記のように構成した保持部材７０は、連結壁部４３の表面４３ｄに熱膨張性部材６０が貼り付けられた後に気密材保持壁部４４と外レール部４２との間に装着されることになる。上述したように、常態においては、保持部材７０の基板部７１を構成する垂直当接部７１ａ、傾斜当接部７１ｂ、水平当接部７１ｃの相互屈曲角度や押圧片部７２，７３との屈曲角度が、連結壁部４３を構成する垂直延在部４３ａ、傾斜延在部４３ｂ、水平延在部４３ｃの相互屈曲角度や外レール部４２、気密材保持壁部４４との屈曲角度よりも大きいため、撓んだ状態で気密材保持壁部４４及び外レール部４２の間に装着されることになる。 The holding member 70 configured as described above is mounted between the airtight material holding wall portion 44 and the outer rail portion 42 after the thermal expansion member 60 is attached to the surface 43d of the connecting wall portion 43. Become. As described above, in the normal state, the mutual bending angle of the vertical contact portion 71a, the inclined contact portion 71b, and the horizontal contact portion 71c constituting the substrate portion 71 of the holding member 70 and the bending of the pressing pieces 72 and 73. The angle is larger than the mutual bending angle of the vertical extending portion 43a, the inclined extending portion 43b, and the horizontal extending portion 43c constituting the connecting wall portion 43, and the bending angle with the outer rail portion 42 and the airtight material holding wall portion 44. Therefore, it is mounted between the airtight material holding wall portion 44 and the outer rail portion 42 in a bent state.

これにより、気密材保持壁部４４と外レール部４２との間に装着した後においては、保持部材７０が自己の弾性復元力によって下枠１１に装着された状態が維持されることになる。すなわち、第２の押圧片部７３が気密材保持壁部４４の下面に押圧されるとともに、第１の押圧片部７２が外レール部４２において室内側の表面に押圧されることで下枠１１からの脱落が阻止され、さらには基板部７１によって熱膨張性部材６０が連結壁部４３の表面４３ｄに押圧された状態となる。従って、仮に、経年劣化によって連結壁部４３と熱膨張性部材６０との間に設けた両面テープの接着性が弱くなったり、外部から熱膨張性部材６０に外力が加えられたとしても、下枠１１から熱膨張性部材６０が脱落する事態は、保持部材７０によって阻止されることになり、長期にわたって建具に高い防火性能を確保することが可能となる。しかも、保持部材７０の弾性復元力によって保持部材７０を下枠１１に保持させるとともに、熱膨張性部材６０の剥がれを防止するようにしているため、ネジ等の部品が別に必要になることがない。このため、下枠１１に対してネジ孔を設ける等の加工を施す必要がなく、製造作業を容易化することができるとともに、製造コストの削減を図ることも可能となる。 As a result, after mounting between the airtight material holding wall portion 44 and the outer rail portion 42, the holding member 70 is maintained in a state of being mounted on the lower frame 11 by its own elastic restoring force. That is, the second pressing piece portion 73 is pressed against the lower surface of the airtight material holding wall portion 44, and the first pressing piece portion 72 is pressed against the indoor surface of the outer rail portion 42, whereby the lower frame 11 Further, the heat-expandable member 60 is pressed against the surface 43d of the connecting wall portion 43 by the substrate portion 71. Therefore, even if the adhesiveness of the double-sided tape provided between the connecting wall portion 43 and the heat-expandable member 60 is weakened due to aged deterioration, or an external force is applied to the heat-expandable member 60 from the outside, the bottom The situation where the heat-expandable member 60 falls off from the frame 11 is prevented by the holding member 70, and it is possible to secure high fire protection performance for the fittings for a long period of time. Moreover, since the holding member 70 is held by the lower frame 11 by the elastic restoring force of the holding member 70 and the heat-expandable member 60 is prevented from peeling off, parts such as screws are not required separately. .. Therefore, it is not necessary to perform processing such as providing screw holes on the lower frame 11, and the manufacturing work can be facilitated and the manufacturing cost can be reduced.

加えて、熱膨張性部材６０に位置決め用目印６２を設けるようにしているため、所望となる位置に保持部材７０を正確に装着することができるばかりでなく、保持部材７０の装着忘れを認識できるようになり、熱膨張性部材６０が下枠１１から脱落する事態をより確実に防止することができる。さらに、位置決めされた保持部材７０は、係止片部７３ｂが熱膨張性部材６０の係止切欠部６３に収容された状態となるため、熱膨張性部材６０に対して保持部材７０が位置ずれする事態を招来するおそれもない。しかも、建具を外部から視認した場合に、気密材保持壁部４４によって覆われる熱膨張性部材６０の第１平面膨張部６０ａに係止切欠部６３を設けるようにしているため、係止片部７３ｂや係止切欠部６３が外部に露出することがなく、建具の外観品質が損なわれる事態を招来することがない。逆に、覗き込むことで外部から容易に視認可能となる熱膨張性部材６０の第３平面膨張部６０ｃに位置決め用目印６２を設けるようにしているため、保持部材７０を正確な位置に装着する作業を容易に実施可能である。 In addition, since the heat-expandable member 60 is provided with the positioning mark 62, not only the holding member 70 can be accurately mounted at a desired position, but also the forgetting to mount the holding member 70 can be recognized. As a result, it is possible to more reliably prevent the thermal expansion member 60 from falling off from the lower frame 11. Further, in the positioned holding member 70, since the locking piece portion 73b is housed in the locking notch portion 63 of the thermal expansion member 60, the holding member 70 is displaced with respect to the thermal expansion member 60. There is no risk of inviting a situation. Moreover, when the fitting is visually recognized from the outside, the locking notch 63 is provided in the first plane expansion portion 60a of the heat-expandable member 60 covered by the airtight material holding wall portion 44, so that the locking piece portion The 73b and the locking notch 63 are not exposed to the outside, and the appearance quality of the fitting is not impaired. On the contrary, since the positioning mark 62 is provided on the third plane expansion portion 60c of the thermal expansion member 60 that can be easily seen from the outside by looking into it, the holding member 70 is mounted at an accurate position. The work can be carried out easily.

さらに、保持部材７０の第２の押圧片部７３に逃げ部７３ａが設けてある。従って、図５に示すように、気密材保持壁部４４において逃げ部７３ａに対応する部分にネジ（位置決め手段：突部）７４を螺合することによって突部を形成すれば、下枠１１に対する保持部材７０の位置決めを行うことが可能となる。このネジ７４は、位置決めのためだけに下枠１１に設けても良いし、下枠１１に部品を取り付けるためのものを兼用することも可能である。なお、下枠１１に設ける突部は必ずしもネジである必要はなく、下枠１１に設けた孔に嵌合する部材であっても良いし、下枠１１に一体に設けるようにしても構わない。 Further, a relief portion 73a is provided on the second pressing piece portion 73 of the holding member 70. Therefore, as shown in FIG. 5, if the protrusion is formed by screwing the screw (positioning means: protrusion) 74 into the portion of the airtight material holding wall portion 44 corresponding to the relief portion 73a, the protrusion is formed with respect to the lower frame 11. The holding member 70 can be positioned. The screw 74 may be provided on the lower frame 11 only for positioning, or may also be used for attaching a component to the lower frame 11. The protrusion provided on the lower frame 11 does not necessarily have to be a screw, and may be a member that fits into the hole provided on the lower frame 11, or may be provided integrally with the lower frame 11. ..

なお、上述した実施の形態では、引き違い窓の下枠１１を例示しているが、必ずしも下枠１１である必要はなく、枠体の上枠や縦枠１２、あるいは障子を構成する框でも良いし、これらの枠や框を補強するための補強材等々、その他の建材に熱膨張性部材を設ける場合にも適用することが可能である。また、保持部材７０についても実施の形態のものに限らず、弾性復元力によって建材に装着された状態を維持し、かつ弾性復元力によって熱膨張性部材を建材に押圧することのできるものであれば、その他の形状のものでも良い。この場合、保持部材としては必ずしも金属によって成形する必要はなく、樹脂によって成形することも可能である。 In the above-described embodiment, the lower frame 11 of the sliding window is illustrated, but the lower frame 11 does not necessarily have to be the lower frame 11, and the upper frame of the frame, the vertical frame 12, or the stile constituting the shoji screen may be used. However, it can also be applied to the case where a heat-expandable member is provided in other building materials such as a reinforcing material for reinforcing these frames and frames. Further, the holding member 70 is not limited to the one of the embodiment, and may be a member that can maintain the state of being attached to the building material by the elastic restoring force and can press the thermally expandable member against the building material by the elastic restoring force. For example, other shapes may be used. In this case, the holding member does not necessarily have to be molded from metal, but can also be molded from resin.

It is pressed by 110. That is, the holding member 110 of the first modification is mounted between the first upper fin portion 101 and the second upper fin portion (press receiving portion) 102 extending vertically facing the first upper fin portion 101. The flat plate-shaped substrate portion 111 and the two flat plate-shaped pressing pieces 112 and 113 extending from both side ends of the substrate portion 111 are integrally formed by a thin metal plate. As shown by the alternate long and short dash line in the figure, in the normal state, the two pressing piece portions 112 and 113 of the holding member 110 are inclined with respect to the substrate portion 111 so as to gradually separate from each other. The maximum dimension of the two pressing pieces 112 and 113 in the normal state is larger than the mutual distance between the first upper fin portion 101 and the second upper fin portion 102. In the state where the holding member 110 is attached to the upper frame 100, one pressing piece portion 112 is pressed against the first upper fin portion 101 via the heat-expandable member 60, and the other pressing piece portion 113 is second upper. It is pressed against the fin portion 102. That is, the holding member 110 is maintained in a state of being attached to the upper frame 100 by the elastic restoring force, and the heat-expandable member 60 is pressed against the first upper fin portion 101 by the elastic restoring force.

図６（ｂ）の下枠２００に示す変形例２は、上下に延在する第１下ヒレ部２０１の室内に臨む見付け面２０１ａを取付表面として配設された熱膨張性部材６０を保持部材２１０によって押圧するものである。保持部材２１０は、第１下ヒレ部２０１と、第１下ヒレ部２０１に対向して上下に延在する第２下ヒレ部（押圧受部）２０２との間に装着されるもので、平板状を成す基板部２１１と、基板部２１１の両側端部から延在した２つの平板状を成す２つの押圧片部２１２，２１３とが金属薄板によって一体に成形してある。図中の２点鎖線で示すように、常態においては、保持部材２１０の２つの押圧片部２１２，２１３が漸次離反するように基板部２１１に対して傾斜している。常態における２つの押圧片部２１２，２１３の最大寸法は、第１下ヒレ部２０１と第２下ヒレ部２０２との相互間隔よりも大きい。下枠２００に保持部材２１０が装着された状態においては、一方の押圧片部２１２が熱膨張性部材６０を介して第１下ヒレ部２０１に押圧され、他方の押圧片部２１３が第２下ヒレ部２０２に押圧される。つまり、保持部材２１０は、弾性復元力によって下枠２００に装着した状態が維持され、かつ弾性復元力によって熱膨張性部材６０を第１下ヒレ部２０１に押圧した状態となる。 In the modified example 2 shown in the lower frame 200 of FIG. 6B, the heat-expandable member 60 arranged with the finding surface 201a facing the room of the first lower fin portion 201 extending vertically is a holding member. It is pressed by 210. The holding member 210 is mounted between the first lower fin portion 201 and the second lower fin portion (pressing receiving portion) 202 extending vertically facing the first lower fin portion 201, and is a flat plate. The shaped substrate portion 211 and the two flat pressing piece portions 212 and 213 extending from both side ends of the substrate portion 211 are integrally formed by a thin metal plate. As shown by the alternate long and short dash line in the figure, in the normal state, the two pressing piece portions 212 and 213 of the holding member 210 are inclined with respect to the substrate portion 211 so as to gradually separate from each other. The maximum dimension of the two pressing piece portions 212 and 213 in the normal state is larger than the mutual distance between the first lower fin portion 201 and the second lower fin portion 202. In the state where the holding member 210 is attached to the lower frame 200, one pressing piece portion 212 is pressed against the first lower fin portion 201 via the thermally expandable member 60, and the other pressing piece portion 213 is second lower. It is pressed by the fin portion 202. That is, the holding member 210 is maintained in a state of being attached to the lower frame 200 by the elastic restoring force, and the heat-expandable member 60 is pressed against the first lower fin portion 201 by the elastic restoring force.

図６（ｂ）の下枠２００に示す変形例３は、上下に延在する第４下ヒレ部２０４の室外に臨む見付け面２０４ａを取付表面として配設された熱膨張性部材６０を保持部材２２０によって押圧するものである。保持部材２２０は、第４下ヒレ部２０４と、第４下ヒレ部２０４に対向して上下に延在する第３下ヒレ部（押圧受部）２０３との間に装着されるもので、平板状を成す基板部２２１と、基板部２２１の両側端部から延在した平板状を成す２つの押圧片部２２２，２２３とが金属薄板によって一体に成形してある。この変形例３においては、第３下ヒレ部２０３と、第４下ヒレ部２０４とが中空部を構成している。図中の２点鎖線で示すように、常態においては、保持部材２２０の２つの押圧片部２２２，２２３が漸次離反するように基板部２２１に対して傾斜している。常態における２つの押圧片部２２２，２２３の最大寸法は、第３下ヒレ部２０３と第４下ヒレ部２０４との相互間隔よりも大きい。下枠２００に対しては、中空部の開口端から熱膨張性部材６０の両端部にのみ装着すれば良い。下枠２００に保持部材２２０が装着された状態においては、一方の押圧片部２２２が第３下ヒレ部２０３に押圧され、他方の押圧片部２２３が熱膨張性部材６０を介して第４下ヒレ部２０４に押圧される。つまり、保持部材２２０は、弾性復元力によって下枠２００に装着した状態が維持され、かつ弾性復元力によって熱膨張性部材６０を第４下ヒレ部２０４に押圧した状態となる。 In the modified example 3 shown in the lower frame 200 of FIG. 6B, the heat-expandable member 60 is held by the heat-expandable member 60 arranged with the finding surface 204a facing the outside of the fourth lower fin portion 204 extending vertically as the mounting surface.

The shaped substrate portion 221 and the two flat pressing piece portions 222 and 223 extending from both side ends of the substrate portion 221 are integrally formed by a thin metal plate. In this modification 3, the third lower fin portion 203 and the fourth lower fin portion 204 form a hollow portion. As shown by the alternate long and short dash line in the figure, in the normal state, the two pressing piece portions 222 and 223 of the holding member 220 are inclined with respect to the substrate portion 221 so as to gradually separate from each other. The maximum dimension of the two pressing piece portions 222 and 223 in the normal state is larger than the mutual distance between the third lower fin portion 203 and the fourth lower fin portion 204. The lower frame 200 may be attached only to both ends of the heat-expandable member 60 from the open end of the hollow portion. In the state where the holding member 220 is attached to the lower frame 200, one pressing piece portion 222 is pressed by the third lower fin portion 203, and the other pressing piece portion 223 is pressed by the fourth lower portion via the thermally expandable member 60. It is pressed against the fin portion 204. That is, the holding member 220 is maintained in a state of being attached to the lower frame 200 by the elastic restoring force, and the heat-expandable member 60 is pressed against the fourth lower fin portion 204 by the elastic restoring force.

図６（ｂ）の下枠２００に示す変形例４は、実施の形態と同様のものである。すなわち、上下に沿って延在する第７下ヒレ部２０７の室内に臨む見付け面２０７ａを取付表面として配設された熱膨張性部材６０を保持部材２３０によって押圧するものである。保持部材２３０は、第７下ヒレ部２０７の上下両端部から見込み方向に延在した第５下ヒレ部２０５及び第６下ヒレ部２０６をそれぞれ押圧受部として互いの間に装着されるもので、平板状を成す基板部２３１と、基板部２３１の両側端部から延在した平板状を成す２つの押圧片部２３２，２３３とが金属薄板によって一体に成形してある。図中の２点鎖線で示すように、常態においては、保持部材２３０の２つの押圧片部２３２，２３３が漸次離反するように基板部２３１に対して傾斜している。常態における２つの押圧片部２３２，２３３の最大寸法は、第５下ヒレ部２０５と第６下ヒレ部２０６との相互間隔よりも大きい。第５下ヒレ部２０５は、ほぼ水平となるように延在している一方、第６下ヒレ部２０６は、室外に向けて漸次下方となるように傾斜している。下枠２００に保持部材２３０が装着された状態においては、一方の押圧片部２３２が第５下ヒレ部２０５に押圧され、他方の押圧片部２３３が第６下ヒレ部２０６に押圧される。つまり、保持部材２３０は、弾性復元力によって下枠２００に装着した状態が維持され、弾性復元力によって基板部２３１を介して熱膨張性部材６０を第７下ヒレ部２０７に押圧した状態となる。 Modification 4 shown in the lower frame 200 of FIG. 6B is the same as that of the embodiment. That is, the holding member 230 presses the heat-expandable member 60 arranged with the finding surface 207a facing the room of the seventh lower fin portion 207 extending along the upper and lower sides as the mounting surface. The holding member 230 is mounted between the fifth lower fin portion 205 and the sixth lower fin portion 206, which extend in the prospective direction from the upper and lower ends of the seventh lower fin portion 207, as pressing receiving portions, respectively. The flat plate-shaped substrate portion 231 and the two flat plate-shaped pressing pieces 232 and 233 extending from both side ends of the substrate portion 231 are integrally formed by a thin metal plate. As shown by the alternate long and short dash line in the figure, in the normal state, the two pressing piece portions 232 and 233 of the holding member 230 are inclined with respect to the substrate portion 231 so as to gradually separate from each other.
