Description
本発明は、骨材を四周枠組みして構成した構造枠の両面にそれぞれ表面材を設けることよって面材本体が構成される建具用面材及び建具に関するものである。 The present invention relates to a face material for a fitting and a fitting, in which a face material main body is configured by providing a surface material on both surfaces of a structural frame configured by arranging four frames of aggregate.
建物の玄関ドアでは、建具用面材として、いわゆるフラッシュパネルが多く適用されている。フラッシュパネルは、例えば、骨材を四周枠組みして構造枠を構成し、この構造枠の両面に表面材を設けることによって面材本体が構成されている。表面材の周縁部には、骨材を覆うように折り曲げ部が設けられている。それぞれの表面材は、折り曲げ部を介して骨材にリベットを打つことにより、骨材に固定されている（例えば、特許文献１参照）。 In the entrance doors of buildings, so-called flash panels are often used as surface materials for fittings. The flash panel has, for example, a face material main body formed by forming a structural frame by framing the aggregate four times and providing surface materials on both surfaces of the structural frame. A bent portion is provided on the peripheral portion of the surface material so as to cover the aggregate. Each surface material is fixed to the aggregate by riveting the aggregate through the bent portion (see, for example, Patent Document 1).
ところで、上述の建具用面材では、火災発生時等のように高温に晒された場合、表面材に熱伸び等の熱変形が生じる。ここで、表面材の折り曲げ部と骨材との固定点数を少なく設定した場合には、つまり折り曲げ部と骨材との固定点の相互間隔が大きい場合には、折り曲げ部が長いスパンで変形することができる。このため、例えば建具用面材が高温状態となると、折り曲げ部が見込み方向に沿って面外側に移動し、表面材の周縁部が面外側に大きく膨らむように変形するおそれがある。表面材が上記のように変形した場合には、室内外に火炎の貫通口を生じる等の問題を招来することになり、防火性の点で不利となる。 By the way, in the above-mentioned surface material for fittings, when it is exposed to a high temperature such as when a fire occurs, the surface material undergoes thermal deformation such as thermal expansion. Here, when the number of fixing points between the bent portion of the surface material and the aggregate is set to be small, that is, when the mutual distance between the fixed points of the bent portion and the aggregate is large, the bent portion deforms with a long span. be able to. Therefore, for example, when the surface material for fittings is in a high temperature state, the bent portion may move to the outside of the surface along the prospective direction, and the peripheral portion of the surface material may be deformed so as to largely expand to the outside of the surface. When the surface material is deformed as described above, it causes a problem such as a flame penetration opening inside and outside the room, which is disadvantageous in terms of fire resistance.
一方、表面材の折り曲げ部と骨材との固定点数を多く設定した場合には、つまり折り曲げ部と骨材との固定点の相互間隔が小さい場合には、折り曲げ部が短いスパンでしか変形することができず、見込み方向に沿って面外側に移動するおそれがなくなるため、表面材の周縁部が面外側に大きく膨らむように変形することもない。しかしながら、高温状態となった表面材にあっては、折り曲げ部で吸収できなかった熱伸びの影響により面材本体の表面側に歪み等の変形を来すおそれがある。このため、例えば縦枠に設けられた戸当たり部に加熱発泡材等の熱膨張性部材を設けたとしても、室内側に配置される表面材の表面が歪みによって凹凸状となり、膨張した熱膨張性部材と表面材との間に隙間が生じるおそれがある。特に、間隔をおいて複数箇所にヒンジが設けられる面材本体の吊り元側においては、最下方に配置されるヒンジとその上部に配置されるヒンジとの間にリベットを打った場合、折り曲げ部が見込み方向に沿って面外側に移動するような熱変形は防止できるものの、面材本体の表面側が歪んで凹凸状に変形するおそれがある。加えて、面材本体の上方部に比べて温度が低い面材本体の下方部においては、戸当たり部に設けられた熱膨張性部材の膨張量も減少気味となる結果、面材本体の下方部において上述した隙間の問題が生じやすい。 On the other hand, when a large number of fixing points between the bent portion of the surface material and the aggregate are set, that is, when the mutual distance between the fixed points of the bent portion and the aggregate is small, the bent portion deforms only in a short span. Since it is impossible to move to the outside of the surface along the prospective direction, the peripheral portion of the surface material is not deformed so as to largely bulge to the outside of the surface. However, in the case of the surface material that has reached a high temperature, there is a risk that the surface side of the surface material body may be deformed, such as by distortion, due to the influence of thermal expansion that cannot be absorbed by the bent portion. Therefore, for example, even if a heat-expandable member such as a heat-foaming material is provided in the door stop provided on the vertical frame, the surface of the surface material arranged on the indoor side becomes uneven due to strain, and the expanded thermal expansion is caused. There is a possibility that a gap may occur between the elastic member and the surface material. In particular, when the rivet is struck between the hinge arranged at the lowermost part and the hinge arranged at the upper part on the hanging side of the face material main body in which the hinges are provided at a plurality of places at intervals, the bent portion Although it is possible to prevent thermal deformation such that is moved to the outside of the surface along the prospective direction, the surface side of the face material main body may be distorted and deformed into an uneven shape. In addition, in the lower part of the face material main body where the temperature is lower than the upper part of the face material main body, the expansion amount of the heat-expandable member provided in the door stop part tends to decrease, as a result, In the part, the above-mentioned problem of the gap is likely to occur.
本発明は、上記実情に鑑みて、防火性の向上を図ることのできる建具用面材及び建具を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a face material for fittings and a fitting that can improve fire protection.
上記目的を達成するため、本発明に係る建具用面材は、骨材を四周枠組みした構造枠の両面にそれぞれ表面材が設けられるとともに、前記表面材の周縁部に設けた折り曲げ部によって前記骨材を覆うことにより面材本体が構成される建具用面材であって、前記面材本体の吊り元側となる見込み面には、複数のヒンジが設けられ、前記面材本体の吊り元側となる見込み面において最下方に配置されるヒンジと、直上に配置されるヒンジとの間には、室外側に配置される表面材の折り曲げ部にのみ前記骨材との間を固定するリベットが設けられていることを特徴とする。 In order to achieve the above-mentioned object, the surface material for fittings according to the present invention is provided with a surface material on both sides of a structural frame in which an aggregate is framed around four sides, and the bone is formed by a bent portion provided on a peripheral portion of the surface material. A face material for joinery in which a face material main body is formed by covering the material, and a plurality of hinges are provided on a prospective surface that is a hanging base side of the face material main body, and a hanging base side of the face material main body. The rivet that fixes the aggregate to the aggregate only at the bent portion of the surface material that is arranged on the outdoor side is provided between the hinge that is arranged at the bottom of the prospective surface and the hinge that is arranged immediately above. It is characterized by being provided.
また本発明に係る建具は、上枠及び左右の縦枠を備えた枠体と、上述した建具用面材とを備え、前記ヒンジを介して前記建具用面材が前記縦枠の一方に取り付けられた建具であって、前記縦枠には、前記建具用面材よりも室内側となる部分に戸当たり部が設けられ、前記戸当たり部の室外に臨む面に熱膨張性部材が設けられていることを特徴とする。 Further, the fitting according to the present invention includes a frame body including an upper frame and left and right vertical frames, and the above-described facing material for fitting, and the facing material for fitting is attached to one of the vertical frames via the hinge. In the vertical frame, the vertical frame is provided with a door stop portion in a portion that is closer to the indoor side than the surface material for the door fastener, and a thermal expansion member is provided on a surface of the door stop portion that faces the outside. It is characterized by
また本発明に係る建具は、上枠及び左右の縦枠を備えた枠体と、上述した建具用面材とを備え、前記ヒンジを介して前記建具用面材が前記縦枠の一方に取り付けられた建具であって、前記縦枠には、前記建具用面材の室内側に配置される表面材よりも室内側となる見込み面に熱膨張性部材が設けられていることを特徴とする。 Further, the fitting according to the present invention includes a frame body including an upper frame and left and right vertical frames, and the above-described facing material for fitting, and the facing material for fitting is attached to one of the vertical frames via the hinge. The above-mentioned vertical frame is characterized in that the vertical frame is provided with a heat-expandable member on a prospective surface which is on the indoor side of the surface material arranged on the indoor side of the surface material for the fitting. ..
本発明に係る建具用面材によれば、室内側に配置される表面材にはヒンジの相互間に位置する折り曲げ部にリベットが設けられないため、折り曲げ部と骨材との固定点の相互間隔が大きく確保されることになり、面材本体の表面側に歪み等の熱変形が及ぶ事態を招来するおそれがない。しかも、室内側に配置される表面材には、室内に臨む表面縁部に戸当たり部が近接して配置されるため、折り曲げ部が見込み方向に沿って面外側に移動するような変形を来すおそれもない。一方、室外側に配置される表面材には、ヒンジの相互間に位置する折り曲げ部にリベットが設けられるため、折り曲げ部と骨材との固定点の相互間隔が小さくなり、高温に晒された場合にも折り曲げ部が見込み方向に沿って面外側に移動するような変形を来すおそれがない。仮に、室外側に配置される表面材の表面が歪みによって凹凸状となった場合にもこの凹凸が防火性に影響を及ぼすことがない。これらの結果、枠体との間に火炎の貫通口が生じるおそれがなくなり、防火性の点で有利となる。 According to the surface material for a fitting according to the present invention, since the rivet is not provided in the bent portion located between the hinges on the surface material arranged on the indoor side, the fixing points of the bent portion and the aggregate do not interact with each other. Since a large space is secured, there is no possibility of causing thermal deformation such as distortion on the surface side of the face material body. Moreover, since the door contact portion is arranged close to the surface edge facing the room, the surface material arranged on the room side is deformed such that the bent portion moves outward along the prospective direction. There is no danger of it. On the other hand, in the surface material arranged on the outdoor side, rivets are provided at the bent portions located between the hinges, so that the distance between the fixed points of the bent portion and the aggregate becomes small, and the surface material was exposed to high temperature. Also in this case, there is no possibility that the bent portion is deformed such that it moves to the outside of the surface along the prospective direction. Even if the surface of the surface material arranged on the outdoor side becomes uneven due to strain, the unevenness does not affect the fireproof property. As a result, there is no possibility that a flame through hole will be formed between the frame and the frame, which is advantageous in terms of fire resistance.
また、本発明に係る建具によれば、熱膨張性部材が膨張した場合に、建具用面材と縦枠との間を確実に閉塞することができ、防火性の点で有利となる。 Further, according to the fitting according to the present invention, when the heat-expandable member expands, it is possible to reliably block the space between the fitting face material and the vertical frame, which is advantageous in terms of fire prevention.

The water drainage hole 24a is a rectangular notch having a prospective dimension that allows the insertion portion 44 of the corner cap 40 described above to be inserted therein. The dimension of the drainage hole 24a along the longitudinal direction of the lower aggregate 24 is set to be larger than the dimension of the corner cap 40 from the side cover portion 42 to the extending edge portion of the lower cover portion 41. The engaging piece portion 206 is a small rectangular piece having a small width and formed in a portion of the bent portion 204 covering the lower aggregate 24 corresponding to the drainage hole 24a of the lower aggregate 24. The distance from the prospective surface 20c located on the suspension base side of the door panel 20 to the engaging piece portion 206 is set to be substantially equal to the distance from the side cover portion 42 of the corner cap 40 to the insertion portion 44.
このコーナーキャップ４０は、折り曲げ部２０４に設けた係合片部２０６をそれぞれ上方に折り曲げた後、側方カバー部４２がドアパネル２０の見込み面２０ｃに当接するようにドアパネル２０の下方から下方隅部に装着してある。コーナーキャップ４０の挿入部４４が水抜き孔２４ａに嵌合することで、表面材２６，２７の係合片部２０６が挿入部４４と下骨材２４との間に挟持された状態となる。このため、係合片部２０６が折り曲げ部２０４に沿った元の姿勢に戻るおそれがなくなり、外力を加えて表面材２６，２７を引き離そうとしても、下骨材２４に対する表面材２６，２７の移動が阻止されることになる。なお、このコーナーキャップ４０は、ネジ挿通孔４３ａを介して縦骨材２２にネジ４５を螺合することでドアパネル２０に取り付けられた状態が維持されている。 The corner cap 40 is formed by bending the engaging piece portions 206 provided on the bent portion 204 upward, and then, from below the door panel 20 so that the side cover portion 42 contacts the prospective surface 20c of the door panel 20. It is attached to. By fitting the insertion portion 44 of the corner cap 40 into the drainage hole 24a, the engagement piece portion 206 of the surface material 26, 27 is sandwiched between the insertion portion 44 and the lower aggregate 24. Therefore, there is no possibility that the engagement piece portion 206 will return to the original posture along the bent portion 204, and even if an external force is applied to separate the surface materials 26 and 27, the surface materials 26 and 27 with respect to the lower aggregate 24 will not move. Movement will be blocked. The corner cap 40 is kept attached to the door panel 20 by screwing a screw 45 into the vertical aggregate 22 through the screw insertion hole 43a.
リベット５０は、表面材２６の折り曲げ部２０４と縦骨材２２との間を固定するもので、２つのヒンジ３０のほぼ中間となり、かつ折り曲げ部２０４の見込み方向のほぼ中間となる部位に設けてある。 The rivet 50 fixes between the bent portion 204 of the surface material 26 and the vertical aggregate 22, and is provided at a position substantially in the middle of the two hinges 30 and substantially in the expected direction of the bent portion 204. is there.
上記のように構成した玄関ドアによれば、火災発生時において高温状態に晒されると、個々の枠の戸当たり部１１ｂ，１２ｂ，１３ｂ，１４ｂに配設した熱膨張性部材１６が膨張することにより、ドアパネル２０と枠体１０との隙間を埋めるように機能する。一方、高温状態となったドアパネル２０の表面材２６，２７には、熱変形が招来されることになる。 According to the entrance door configured as described above, when exposed to a high temperature state in the event of a fire, the heat-expandable member 16 arranged in the door stop portions 11b, 12b, 13b, 14b of the individual frames expands. This functions to fill the gap between the door panel 20 and the frame 10. On the other hand, the surface materials 26 and 27 of the door panel 20 which have reached a high temperature are thermally deformed.
ここで、比較的高温状態となるドアパネル２０の上方部においては、熱膨張性部材１６の膨張量も十分となる。しかも、戸先側においては、全長にわたってエッジ材２０５が設けてあり、室外側に配置される表面材２６及び室内側に配置される表面材２７の双方において折り曲げ部２０４の変形が抑えられた状態にある。吊り元側においても、中間部のヒンジ３０が上方寄りに設けてあり、上方部のヒンジ３０との相互間隔が小さいため、室外側に配置される表面材２６及び室内側に配置される表面材２７の双方において折り曲げ部２０４が短いスパンでしか変形することができない。これらの結果、ドアパネル２０の上方部においては、高温状態に晒された場合にも、折り曲げ部２０４が見込み方向に沿って面外側に移動するような変形を来すおそれがない。仮に室内側に配置される表面材２７の表面板部２０３に凹凸状の熱変形を来していた場合にも、十分に膨張した熱膨張性部材１６によって凹凸部分が確実に塞がれるため、枠体１０とドアパネル２０との間に火炎の貫通口となる隙間が生じるおそれはない。 Here, the amount of expansion of the heat-expandable member 16 is sufficient in the upper portion of the door panel 20, which is in a relatively high temperature state. Moreover, the edge member 205 is provided over the entire length on the door end side, and the deformation of the bent portion 204 is suppressed in both the surface material 26 arranged on the outdoor side and the surface material 27 arranged on the indoor side. It is in. Also on the hanging side, since the hinge 30 in the middle part is provided in the upper side and the mutual interval with the hinge 30 in the upper part is small, the surface material 26 arranged on the outdoor side and the surface material arranged on the indoor side. In both 27, the fold 204 can only be deformed in a short span. As a result of these, the upper portion of the door panel 20 is not likely to be deformed such that the bent portion 204 moves to the outside of the surface along the prospective direction even when exposed to a high temperature state. Even if the surface plate portion 203 of the surface material 27 arranged on the indoor side is subjected to uneven thermal deformation, the sufficiently expanded thermal expansion member 16 reliably closes the uneven portion. There is no possibility that a gap will be formed between the frame body 10 and the door panel 20 as a flame through hole.
一方、ドアパネル２０の中間部から下方部では、室外側に配置される表面材２６の折り曲げ部２０４において下方部のヒンジ３０と中間部のヒンジ３０との間にリベット５０が設けてある。従って、高温状態に晒された場合にも、表面材２６の折り曲げ部２０４が見込み方向に沿って面外側に移動するような変形を招来するおそれがない。 On the other hand, from the middle part to the lower part of the door panel 20, a rivet 50 is provided between the lower part hinge 30 and the middle part hinge 30 in the bent part 204 of the surface material 26 arranged on the outdoor side. Therefore, even when the surface material 26 is exposed to a high temperature, there is no possibility that the bent portion 204 of the surface material 26 is deformed such that it moves to the outside of the surface along the prospective direction.
これに対して室内側に配置される表面材２７の折り曲げ部２０４には、下方部のヒンジ３０と中間部のヒンジ３０との間にリベット５０を設けていない。しかしながら、室内側に配置される表面材２７には、室内に臨む表面２０ａの縁部に戸当たり部１２ｂが近接して配置されるため、戸当たり部１２ｂによって折り曲げ部２０４が見込み方向に沿って面外側に移動する事態が防止されることになる。従って、折り曲げ部２０４が面外側に移動することに起因して枠体１０とドアパネル２０との間に火炎の貫通口が生じるおそれはない。 On the other hand, in the bent portion 204 of the surface material 27 arranged on the indoor side, the rivet 50 is not provided between the lower hinge 30 and the intermediate hinge 30. However, since the door stop 12b is arranged close to the edge of the surface 20a facing the room on the surface material 27 arranged on the indoor side, the bent part 204 is formed along the prospective direction by the door stop 12b. The situation of moving to the outside of the plane will be prevented. Therefore, there is no possibility that a flame penetration hole is formed between the frame body 10 and the door panel 20 due to the bending portion 204 moving to the outside of the surface.
さらに、上述のドアパネル２０では、室内側に配置される表面材２７の折り曲げ部２０４において下方部のヒンジ３０と中間部のヒンジ３０との間にリベット５０による固定点がないため、室外側の表面材２６に比較して固定点の相互間隔が大きく確保されることになる。このため、図５（ａ）中の２点鎖線で示すように、折り曲げ部２０４が長いスパンで緩やかな円弧状に変形することで熱伸びの影響が吸収され、室内側に配置される表面材２７の表面板部２０３に凹凸状の歪みを来す事態を招来するおそれがなくなる。 Further, in the door panel 20 described above, there is no fixing point by the rivet 50 between the lower hinge 30 and the intermediate hinge 30 in the bent portion 204 of the surface material 27 arranged on the indoor side, so that the outdoor surface As compared with the material 26, a large distance between the fixed points is secured. Therefore, as shown by a chain double-dashed line in FIG. 5A, the bent portion 204 is deformed into a gentle arc shape with a long span to absorb the influence of thermal expansion, and the surface material arranged on the indoor side. There is no risk of causing uneven distortion on the surface plate portion 203 of 27.
つまり、図５（ｂ）に示すように、室外側と同様、室内側の折り曲げ部２０４においても下方部のヒンジ３０と中間部のヒンジ３０との間にリベット５１を設けた場合には、折り曲げ部２０４と縦骨材２２との固定点の相互間隔が小さくなるため、熱伸びの影響が折り曲げ部２０４で吸収しきれなくなる事態が生じ得る。これにより、図５（ｂ）中の２点鎖線で示すように、表面材２７の表面板部２０３に凹凸状の歪みを来たし、熱膨張性部材１６が熱膨張した場合にも互いの間に隙間が残存するおそれがある。 That is, as shown in FIG. 5B, when the rivet 51 is provided between the lower hinge 30 and the intermediate hinge 30 in the indoor bent portion 204 as well as the outdoor side, the bending is not performed. Since the mutual distance between the fixing points of the portion 204 and the vertical aggregate 22 becomes small, the bending portion 204 may not be able to absorb the influence of thermal expansion. As a result, as shown by the chain double-dashed line in FIG. 5B, the surface plate portion 203 of the surface material 27 is unevenly deformed, and even when the heat-expandable member 16 is thermally expanded, it is between them. A gap may remain.
こうした問題を未然に防止するため、上述したように、下方部のヒンジ３０とその直上に配置される中間部のヒンジ３０との間においては、室外側に配置される表面材２６の折り曲げ部２０４にのみリベット５０を設け、室内側においては長いスパンでの変形が可能となる状態を確保して折り曲げ部２０４で熱伸びの影響を吸収するようにしている。これにより、上方部に比べて熱膨張性部材１６の膨張量が減少気味となるドアパネル２０の中間部以下においても、室内側に配置される表面材２７と熱膨張した熱膨張性部材１６との間に隙間ができる事態を確実に防止することができるようになり、防火性の点で有利となる。 In order to prevent such problems, as described above, the bent portion 204 of the surface material 26 arranged on the outdoor side is provided between the lower hinge 30 and the intermediate hinge 30 arranged immediately above the lower hinge 30. The rivet 50 is provided only on the inside of the room to secure a state in which the room can be deformed over a long span, and the bent portion 204 absorbs the influence of thermal expansion. As a result, the surface material 27 disposed on the indoor side and the thermally expanded thermally expandable member 16 are disposed below the middle part of the door panel 20 where the expansion amount of the thermally expandable member 16 tends to decrease compared to the upper part. It becomes possible to reliably prevent a situation in which a gap is formed between them, which is advantageous in terms of fire resistance.
なお、上述した実施の形態では、ヒンジ３０を３つ設けたものを例示しているが、ヒンジ３０は必ずしも３つである必要はない。また、吊り元側の下方隅部にコーナーキャップ４０を設けるようにしているため、下方部のヒンジ３０よりも下方において表面材２６，２７が面外側に膨らむように変形するおそれがなくなる。しかしながら、本発明は必ずしもコーナーキャップ４０を設ける必要はない。なお、下方部のヒンジ３０よりも下方において表面材が面外側に膨らむ変形を抑える場合には、必ずしもコーナーキャップによるものに限らず、例えば、図６に示す変形例１のように、下方部のヒンジ３０よりも下方となる折り曲げ部２０４に補助リベット５２を設けるようにしても良い。なお、変形例１において実施の形態と同様の構成については同一の符号が付してある。 In addition, in the above-described embodiment, the example in which the three hinges 30 are provided is illustrated, but the number of the hinges 30 is not necessarily three. Further, since the corner cap 40 is provided in the lower corner portion on the suspension base side, there is no possibility that the surface materials 26 and 27 are deformed so as to bulge outside the surface below the hinge 30 in the lower portion. However, the present invention does not necessarily require the corner cap 40 to be provided. In order to suppress the deformation of the surface material swelling outward of the surface below the hinges 30 in the lower portion, it is not always necessary to use the corner caps. For example, as in Modification 1 shown in FIG. The auxiliary rivet 52 may be provided on the bent portion 204 below the hinge 30. In addition, in the modification 1, the same components as those of the embodiment are denoted by the same reference numerals.
また、上述した実施の形態では、枠体１０の戸当たり部１１ｂ，１２ｂ，１３ｂ，１４ｂに熱膨張性部材１６を設けるようにしているが、必ずしも戸当たり部１１ｂ，１２ｂ，１３ｂ，１４ｂに設ける必要はなく、例えば、図７に示す変形例２のように、枠１１，１２においてドアパネル２０の室内側に配置される表面材２７よりも室内側となる見込み面１１ｅ，１２ｅに熱膨張性部材１７を設けるようにしても良い。さらに、枠体１０として上枠１３及び左右の縦枠１１，１２が枠本体部１１ａ，１２ａ，１３ａと、戸当たり部１１ｂ，１２ｂ，１３ｂを有する枠部分１１ｃ，１２ｃ，１３ｃとの間に断熱材１１ｄ，１２ｄ，１３ｄを有するものを例示しているが、必ずしも断熱材１１ｄ，１２ｄ，１３ｄを備える枠体１０である必要はない。なお、断熱材１１ｄ，１２ｄ，１３ｄを有する枠体１０において見込み面に熱膨張性部材１６を設ける場合には断熱材１１ｄ，１２ｄ，１３ｄを覆う位置に配設することが好ましい。さらに、枠体１０としては、必ずしも下枠１４を備えている必要はない。 Further, in the above-described embodiment, the heat-expandable member 16 is provided on the door-stop portions 11b, 12b, 13b, 14b of the frame body 10, but it is not necessarily provided on the door-stop portions 11b, 12b, 13b, 14b. It is not necessary, for example, as in the second modification shown in FIG. 7, the thermally expansive members are provided on the prospective surfaces 11e and 12e, which are on the indoor side of the surface material 27 arranged on the indoor side of the door panel 20 in the frames 11 and 12. 17 may be provided. Further, as the frame body 10, the upper frame 13 and the left and right vertical frames 11, 12 are heat-insulated between the frame body parts 11a, 12a, 13a and the frame parts 11c, 12c, 13c having the door stop parts 11b, 12b, 13b. Although the material having the materials 11d, 12d, and 13d is illustrated, the frame body 10 does not necessarily have to include the heat insulating materials 11d, 12d, and 13d. When the thermally expansive member 16 is provided on the prospective surface of the frame body 10 having the heat insulating materials 11d, 12d, and 13d, it is preferable to dispose the heat insulating material 11d, 12d, and 13d at a position to cover the heat insulating material. Further, the frame body 10 does not necessarily have to include the lower frame 14.
以上のように、本発明に係る建具用面材は、骨材を四周枠組みした構造枠の両面にそれぞれ表面材が設けられるとともに、前記表面材の周縁部に設けた折り曲げ部によって前記骨材を覆うことにより面材本体が構成される建具用面材であって、前記面材本体の吊り元側となる見込み面には、複数のヒンジが設けられ、前記面材本体の吊り元側となる見込み面において最下方に配置されるヒンジと、直上に配置されるヒンジとの間には、室外側に配置される表面材の折り曲げ部にのみ前記骨材との間を固定するリベットが設けられていることを特徴としている。 As described above, the surface material for fittings according to the present invention is provided with the surface material on both sides of the structural frame in which the aggregate is framed around the four sides, and the aggregate is formed by the bent portion provided in the peripheral portion of the surface material. A face material for fittings in which a face material main body is constituted by covering, and a plurality of hinges are provided on a prospective surface that is a suspension base side of the face material main body, which is a suspension base side of the face material main body. A rivet is provided between the hinge arranged at the lowermost position on the prospective surface and the hinge arranged immediately above, and is fixed to the aggregate only at the bent portion of the surface material arranged on the outdoor side. It is characterized by
この発明によれば、室内側に配置される表面材にはヒンジの相互間に位置する折り曲げ部にリベットが設けられないため、折り曲げ部と骨材との固定点の相互間隔が大きく確保されることになり、面材本体の表面側に歪み等の熱変形が及ぶ事態を招来するおそれがない。しかも、室内側に配置される表面材には、室内に臨む表面縁部に戸当たり部が近接して配置されるため、折り曲げ部が見込み方向に沿って面外側に移動するような変形を来すおそれもない。一方、室外側に配置される表面材には、ヒンジの相互間に位置する折り曲げ部にリベットが設けられるため、折り曲げ部と骨材との固定点の相互間隔が小さくなり、高温に晒された場合にも折り曲げ部が見込み方向に沿って面外側に移動するような変形を来すおそれがない。仮に、室外側に配置される表面材の表面が歪みによって凹凸状となった場合にもこの凹凸が防火性に影響を及ぼすことがない。これらの結果、枠体との間に火炎の貫通口が生じるおそれがなくなり、防火性の点で有利となる。 According to the present invention, since no rivet is provided in the bent portion located between the hinges on the surface material arranged on the indoor side, a large mutual gap between the fixing points of the bent portion and the aggregate is secured. Therefore, there is no possibility of causing a situation in which the surface side of the face material body undergoes thermal deformation such as distortion. Moreover, since the door contact portion is arranged close to the surface edge facing the room, the surface material arranged on the room side is deformed such that the bent portion moves outward along the prospective direction. There is no danger of it. On the other hand, in the surface material arranged on the outdoor side, rivets are provided at the bent portions located between the hinges, so that the distance between the fixed points of the bent portion and the aggregate becomes small, and the surface material was exposed to high temperature. Also in this case, there is no possibility that the bent portion is deformed such that it moves to the outside of the surface along the prospective direction. Even if the surface of the surface material arranged on the outdoor side becomes uneven due to strain, the unevenness does not affect the fireproof property. As a result, there is no possibility that a flame through hole will be formed between the frame and the frame, which is advantageous in terms of fire resistance.

この発明によれば、ヒンジを取り付けるためのネジ部材によって表面材の折り曲げ部が骨材に固定されるため、表面材と骨材との間の接合強度を低下させることなくリベットの数を減らすことができ、組立作業の点で有利となる。 According to the present invention, since the bent portion of the surface material is fixed to the aggregate by the screw member for attaching the hinge, it is possible to reduce the number of rivets without lowering the bonding strength between the surface material and the aggregate. This is advantageous in terms of assembly work.
