Abstract
Description
本発明は、枠体や障子を構成するフレーム材に熱膨張性部材が設けられた建具に関するものである。 The present invention relates to a joinery in which a thermally expandable member is provided on a frame material constituting a frame or a shoji.
建具に対して防火性を向上させる方法としては、枠体や障子を構成するフレーム材に膨張性黒鉛等の耐火性を有した熱膨張性部材を配設することが多く行われている。通常、熱膨張性部材は、両面テープによってフレーム材の表面に貼り付けてあるが、経年によって剥がれが生じるおそれがある。このため従来では、フレーム材に保持部材を取り付け、この保持部材によって熱膨張性部材の脱落を防止するようにしている（例えば、特許文献１参照）。 As a method for improving the fire resistance of the joinery, it is often performed to dispose a thermally expandable member having fire resistance such as expandable graphite on the frame material constituting the frame or the shoji. Usually, the heat-expandable member is affixed to the surface of the frame material with a double-sided tape, but there is a risk of peeling over time. For this reason, conventionally, a holding member is attached to the frame material, and the dropping of the thermally expandable member is prevented by this holding member (see, for example, Patent Document 1).
ところで、熱膨張性部材によってより確実に防火性を向上させるには、フレーム材の隣接する部位の複数箇所に熱膨張性部材を配設することが好ましい。すなわち、熱膨張性部材の発泡量を増大させることにより、室内外に貫通口ができる事態をより確実に防止することで建具の防火性を向上させることが可能となる。しかしながら、複数の熱膨張性部材を配設した場合には、保持部材についても複数設けられているのが実情であり、取り扱い部品点数が増大し、製造コストが増大する事態が招来されるばかりか、建具を組み立てる際の作業が煩雑化するおそれがある。 By the way, in order to improve the fire resistance more reliably by the thermally expandable member, it is preferable to dispose the thermally expandable member at a plurality of locations in the adjacent portions of the frame material. That is, by increasing the amount of foaming of the thermally expandable member, it is possible to improve the fire resistance of the joinery by more reliably preventing a situation where a through-hole is formed inside and outside the room. However, in the case where a plurality of thermally expandable members are provided, the fact is that a plurality of holding members are also provided, which not only leads to an increase in the number of handling parts and an increase in manufacturing cost. The work when assembling the joinery may become complicated.
本発明は、上記実情に鑑みて、製造コストが増大したり、組み立ての作業を煩雑化することなく防火性の向上を図ることのできる建具を提供することを目的とする。 In view of the above circumstances, an object of the present invention is to provide a fitting capable of improving fire resistance without increasing manufacturing costs or complicating assembly work.
上記目的を達成するため、本発明に係る建具は、フレーム材に複数の熱膨張性部材が設けられた建具であって、個々の熱膨張性部材に対向する押え面部が一体に形成された保持部材を備え、それぞれの熱膨張性部材に対して対応する押え面部が対向した状態で前記保持部材が前記フレーム材に取り付けられていることを特徴とする。 In order to achieve the above object, a joinery according to the present invention is a joinery in which a plurality of thermally expandable members are provided on a frame material, and a holding surface portion facing each thermally expandable member is integrally formed. The holding member is attached to the frame material in a state in which a pressing surface portion corresponding to each of the thermally expandable members is provided.
この発明によれば、隣接して配置される熱膨張性部材を一つの保持部材によって保持することが可能となり、製造コストが増大する事態や組立作業が煩雑化する事態を招来することなく防火性の向上を図ることが可能となる。 According to the present invention, it is possible to hold the thermally expandable members arranged adjacent to each other by one holding member, and fireproofing without incurring a situation in which the manufacturing cost increases or the assembling work becomes complicated. Can be improved.
また本発明は、上述した建具において、前記フレーム材は、互いに交差する方向に延在した第１の取付面及び第２の取付面を有し、前記第１の取付面及び前記第２の取付面にそれぞれ前記熱膨張性部材が設けられており、前記保持部材には、前記第１の取付面に沿って延在する押え面部と、前記第２の取付面に沿って延在する押え面部とが設けられていることを特徴とする。 Further, according to the present invention, in the joinery described above, the frame material has a first attachment surface and a second attachment surface extending in a direction intersecting each other, and the first attachment surface and the second attachment surface. The heat-expandable member is provided on each surface, and the holding member includes a pressing surface portion extending along the first mounting surface and a pressing surface portion extending along the second mounting surface. And is provided.
この発明によれば、それぞれ熱膨張性部材に対して対応する押え面部を対向させることにより、取り付けの際に保持部材が不用意に回転するおそれがない。従って、単一のネジを螺合させることによって保持部材を容易に、かつ確実にフレーム材に取り付けることができ、作業性を向上させることが可能となる。フレーム材の第１の取付面と第２の取付面とは、互いに凸となるように交差していても良いし、互いに凹となるように交差していても良い。 According to the present invention, the holding member corresponding to the respective heat-expandable member is opposed to the holding member so that the holding member does not rotate carelessly during attachment. Therefore, the holding member can be easily and surely attached to the frame member by screwing a single screw, and the workability can be improved. The first attachment surface and the second attachment surface of the frame material may intersect so as to be convex with each other, or may intersect with each other so as to be concave.
また本発明は、上述した建具において、前記保持部材は、前記第１の取付面に対向する部位にネジが挿通されるネジ挿通孔を有し、前記ネジ挿通孔は、前記第２の取付面に対向する押え面部に対して交差する方向に沿った長孔状に構成されていることを特徴とする。 In the joinery described above, the holding member includes a screw insertion hole through which a screw is inserted into a portion facing the first attachment surface, and the screw insertion hole is the second attachment surface. It is comprised in the shape of a long hole along the direction which cross | intersects with the pressing surface part which opposes.
この発明によれば、長孔に沿って保持部材を移動させることにより、第２の取付面に配設した熱膨張性部材に対して押圧部を確実に当接させることができ、２つの熱膨張性部材の脱落をより確実に防止することが可能となる。 According to this invention, by moving the holding member along the long hole, the pressing portion can be reliably brought into contact with the thermally expandable member disposed on the second mounting surface. It becomes possible to more reliably prevent the expandable member from falling off.
また本発明は、上述した建具において、前記保持部材は、前記フレーム材の表面に当接する当接面部を有するとともに、前記当接面部と前記押え面部との間に段部を有し、前記段部が前記熱膨張性部材の側面に対向した状態で前記フレーム材に取り付けられていることを特徴とする。 According to the present invention, in the joinery described above, the holding member has a contact surface portion that contacts the surface of the frame material, and a step portion between the contact surface portion and the pressing surface portion. It is attached to the said frame material in the state which the part opposed to the side surface of the said thermally expansible member, It is characterized by the above-mentioned.
この発明によれば、段部が熱膨張性部材の側面に当接することで取り付けの際に保持部材の不用意な回転が規制される。従って、単一のネジを螺合させることによって保持部材を容易に、かつ確実にフレーム材に取り付けることができ、作業性を向上させることが可能となる。段部は、必ずしも２つの熱膨張性部材に対して設ける必要はなく、少なくとも一方の熱膨張性部材の側面に対向するように設ければ十分である。 According to this invention, inadvertent rotation of the holding member is restricted at the time of attachment because the stepped portion contacts the side surface of the thermally expandable member. Therefore, the holding member can be easily and surely attached to the frame member by screwing a single screw, and the workability can be improved. The stepped portion is not necessarily provided for the two thermally expandable members, and it is sufficient if the stepped portion is provided so as to face the side surface of at least one of the thermally expandable members.
本発明によれば、隣接して配置される熱膨張性部材を一つの保持部材によって保持することが可能となり、製造コストが増大する事態や組立作業が煩雑化する事態を招来することなく防火性の向上を図ることが可能となる。 According to the present invention, it is possible to hold the thermally expandable members arranged adjacent to each other by one holding member, and fireproofing without incurring a situation in which the manufacturing cost increases or the assembling work becomes complicated. Can be improved.

障子２０の縦框２４には、火災発生時に縦枠１３との間の隙間を塞ぐため、図２〜図４に示すように、外周側となる見込み面２４ｂの２位置に熱膨張性部材３０Ａ，３０Ｂが配設してあるとともに、当接ヒレ部２４ａの室外に臨む見付け面（取付面）２４ｃに熱膨張性部材３０Ａ，３０Ｂ，３０Ｃが配設してある。熱膨張性部材３０Ａ，３０Ｂ，３０Ｃ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３０Ａ，３０Ｂ，３０Ｃ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、幅方向の寸法ａに対して板厚ｂの薄い断面形状を有した長尺状のものを適用し、それぞれ縦框２４の長手に沿って配設してある。図には明示していないが、それぞれの熱膨張性部材３０Ａ，３０Ｂ，３０Ｃは、両面テープによって縦框２４に接着してある。 As shown in FIGS. 2 to 4, in the vertical fence 24 of the shoji 20, a thermal expansion member 30 </ b> A is provided at two positions on the prospective surface 24 b on the outer peripheral side as shown in FIGS. , 30B, and thermal expansion members 30A, 30B, 30C are provided on the finding surface (mounting surface) 24c facing the outside of the contact fin portion 24a. The thermally expandable members 30A, 30B, and 30C are nonflammable or flame retardant fire resistant members that expand due to heat. As this type of thermally expandable members 30A, 30B, and 30C, for example, a graphite-containing foam material having thermally expandable properties can be applied. In the present embodiment, an elongate one having a thin cross-sectional shape with a plate thickness b with respect to the dimension a in the width direction is applied, and each is disposed along the longitudinal length of the downpipe 24. Although not clearly shown in the drawing, each of the thermally expandable members 30A, 30B, and 30C is bonded to the vertical hook 24 with a double-sided tape.
縦框２４の見込み面２４ｂには、室内側の縁部に第１の熱膨張性部材３０Ａが配設してあるとともに、室外側の縁部に第２の熱膨張性部材３０Ｂが配設してある。第１の熱膨張性部材３０Ａは、室内側の縁部が当接ヒレ部２４ａの室外に臨む見付け面２４ｃに接触するように配置してある。第２の熱膨張性部材３０Ｂは、第１の熱膨張性部材３０Ａとの間に隙間を確保し、かつ縦框２４の室外に臨む見付け面２４ｄよりも室内側となる部分に設けてある。図からも明らかなように、縦框２４の見込み面２４ｂには、位置決め用の突条２４ｅが長手に沿って設けてあり、室外側の縁部が突条２４ｅに接触するように第２の熱膨張性部材３０Ｂが配置してある。第１の熱膨張性部材３０Ａについては、縦框２４のほぼ全長にわたる部位に連続して配設してある。これに対して第２の熱膨張性部材３０Ｂは、縦框２４の中間部分にダンパー４０を取り付けるためのブラケット４１が取り付けてあるため、ブラケット４１よりも上方の部分３０Ｂａとブラケット４１よりも下方の部分３０Ｂｂとに分断している。 On the prospective surface 24b of the vertical shaft 24, the first thermally expandable member 30A is disposed at the edge on the indoor side, and the second thermally expandable member 30B is disposed at the edge on the outdoor side. It is. 30 A of 1st thermal expansion members are arrange | positioned so that the edge part of an indoor side may contact the finding surface 24c which faces the outdoor of the contact fin part 24a. The second thermally expansible member 30B is provided in a portion that secures a gap with the first thermally expansible member 30A and that is on the indoor side of the finding surface 24d facing the outdoor side of the vertical rod 24. As is apparent from the figure, the prospective surface 24b of the vertical rod 24 is provided with positioning protrusions 24e along the longitudinal direction, and the second outer edge is in contact with the protrusions 24e. A thermally expandable member 30B is disposed. The first thermally expandable member 30 </ b> A is continuously disposed at a site that extends over substantially the entire length of the downpipe 24. On the other hand, since the bracket 41 for attaching the damper 40 is attached to the middle portion of the vertical shaft 24, the second thermally expandable member 30B has a portion 30Ba above the bracket 41 and a portion below the bracket 41. It is divided into a portion 30Bb.
縦框２４の当接ヒレ部２４ａに配設した第３の熱膨張性部材３０Ｃは、内周側の縁部が第１の熱膨張性部材３０Ａの表面に接触するように配置してある。第３の熱膨張性部材３０Ｃについても、第１の熱膨張性部材３０Ａと同様、縦框２４のほぼ全長にわたる部位に連続して配設してある。 The third thermally expandable member 30C disposed in the contact fin portion 24a of the vertical rod 24 is disposed such that the inner peripheral edge is in contact with the surface of the first thermally expandable member 30A. Similarly to the first thermally expansible member 30A, the third thermally expansible member 30C is continuously disposed in a portion extending over almost the entire length of the downpipe 24.
また、障子２０の縦框２４には、２つの保持部材５０が取り付けてある。保持部材５０は、それぞれ第１の熱膨張性部材３０Ａ、第２の膨張性部材及び第３の熱膨張性部材３０Ｃを同時に保持するためのもので、３つの熱膨張性部材３０Ａ，３０Ｂ，３０Ｃの上端部となる位置及び第２の熱膨張性部材３０Ｂにおいて下方部分３０Ｂｂの上端部となる位置の２箇所に配設してある。 In addition, two holding members 50 are attached to the vertical shaft 24 of the shoji 20. The holding member 50 is for holding the first thermally expandable member 30A, the second expandable member, and the third thermally expandable member 30C at the same time, and is provided with three thermally expandable members 30A, 30B, and 30C. Are disposed at two locations, i.e., the upper end portion of the lower portion 30Bb and the upper end portion of the lower portion 30Bb.
保持部材５０は、鋼材等の金属製薄板を折り曲げることによって一体に成形したもので、当接面部５１を有している。当接面部５１は、第１の熱膨張性部材３０Ａと第２の熱膨張性部材３０Ｂとの間に確保した隙間において縦框２４の見込み面２４ｂに当接する矩形の平板状部分である。縦框２４の見込み方向に沿った当接面部５１の長さ寸法ｃは、第１の熱膨張性部材３０Ａと第２の熱膨張性部材３０Ｂとの相互間隔ｄよりも短く構成してある。この当接面部５１には、互いに平行に延在する２つの縁部に段部５２が設けてある。段部５２は、当接面部５１の表面側に向けて屈曲する部分であり、相互間隔が漸次拡大するように傾斜している。一方の段部５２には、第１の押え面部５３が設けてあり、もう一方の段部５２には、第２の押え面部５４が設けてある。第１の押え面部５３及び第２の押え面部５４は、当接面部５１の延在方向に沿って延在する略矩形の平板状部分である。当接面部５１の裏面５１ａとそれぞれの押え面部５３，５４の裏面５３ａ，５４ａとの間には、熱膨張性部材３０Ａ，３０Ｂ，３０Ｃの板厚ｂよりもわずかに小さい寸法が確保してある。さらに、第１の押え面部５３の延在縁部には、第３の押え面部５５が設けてある。第３の押え面部５５は、第１の押え面部５３から表面側に向けてほぼ直角に屈曲して延在する略矩形の平板状部分である。上述の当接面部５１には、ネジ挿通孔５６が形成してある。ネジ挿通孔５６は、縦框２４の見込み方向に沿って長径となる長孔状を成すものである。なお、図中の符号５７は、保持部材５０を重ねた場合に相互に吸着する事態を防止するために設けた半球状部である。 The holding member 50 is integrally formed by bending a thin metal plate such as a steel material, and has a contact surface portion 51. The abutting surface portion 51 is a rectangular flat plate portion that abuts against the prospective surface 24b of the vertical rod 24 in a gap secured between the first thermally expandable member 30A and the second thermally expandable member 30B. The length dimension c of the contact surface portion 51 along the prospective direction of the vertical rod 24 is configured to be shorter than the mutual distance d between the first thermally expandable member 30A and the second thermally expandable member 30B. The contact surface portion 51 is provided with step portions 52 at two edge portions extending in parallel with each other. The step portion 52 is a portion that bends toward the surface side of the contact surface portion 51, and is inclined so that the mutual interval gradually increases. One step portion 52 is provided with a first pressing surface portion 53, and the other step portion 52 is provided with a second pressing surface portion 54. The first pressing surface portion 53 and the second pressing surface portion 54 are substantially rectangular flat plate portions extending along the extending direction of the contact surface portion 51. A dimension slightly smaller than the plate thickness b of the thermally expandable members 30A, 30B, 30C is secured between the back surface 51a of the contact surface portion 51 and the back surfaces 53a, 54a of the respective pressing surface portions 53, 54. . Further, a third pressing surface portion 55 is provided on the extending edge portion of the first pressing surface portion 53. The third pressing surface portion 55 is a substantially rectangular flat plate-like portion extending from the first pressing surface portion 53 by bending at a substantially right angle toward the surface side. A screw insertion hole 56 is formed in the contact surface portion 51 described above. The screw insertion hole 56 has a long hole shape having a long diameter along the prospective direction of the vertical rod 24. In addition, the code | symbol 57 in a figure is the hemispherical part provided in order to prevent the situation where it adsorb | sucks mutually when the holding member 50 is piled up.
上記のように構成した保持部材５０は、第１の押え面部５３を第１の熱膨張性部材３０Ａに対向させるとともに、第２の押え面部５４を第２の熱膨張性部材３０Ｂに対向させ、さらに第３の押え面部５５を第３の熱膨張性部材３０Ｃに対向させた状態で縦框２４に取り付けてある。縦框２４に保持部材５０を取り付けるには、ネジ挿通孔５６を介して縦框２４の見込み面２４ｂに設けたネジ孔２４ｆにネジ６０を螺合すれば良い。縦框２４に取り付けられた保持部材５０は、第１の押え面部５３が第１の熱膨張性部材３０Ａに押圧され、かつ第２の押え面部５４が第２の熱膨張性部材３０Ｂに押圧された状態となる。また、当接ヒレ部２４ａに配設した第３の熱膨張性部材３０Ｃに対しては、ネジ挿通孔５６が長孔状であるため、保持部材５０を建具の見込み方向に移動させ、第３の押え面部５５を表面に押圧した状態でネジ６０を螺合させることができる。 The holding member 50 configured as described above has the first pressing surface portion 53 opposed to the first thermally expandable member 30A and the second pressing surface portion 54 opposed to the second thermally expandable member 30B. Further, the third pressing surface portion 55 is attached to the vertical rod 24 in a state of being opposed to the third thermally expandable member 30C. In order to attach the holding member 50 to the vertical rod 24, the screw 60 may be screwed into the screw hole 24f provided in the prospective surface 24b of the vertical rod 24 through the screw insertion hole 56. In the holding member 50 attached to the vertical shaft 24, the first pressing surface portion 53 is pressed by the first thermally expandable member 30A, and the second pressing surface portion 54 is pressed by the second thermally expandable member 30B. It becomes the state. In addition, since the screw insertion hole 56 has a long hole shape with respect to the third thermally expandable member 30C disposed in the contact fin portion 24a, the holding member 50 is moved in the expected direction of the fitting, and the third The screw 60 can be screwed in a state where the pressing surface portion 55 is pressed against the surface.
従って、保持部材５０を縦框２４に取り付けた状態においては、仮に経年の影響によって縦框２４とそれぞれの熱膨張性部材３０Ａ，３０Ｂ，３０Ｃとの間の接着状態が解除されたとしても、縦框２４から熱膨張性部材３０Ａ，３０Ｂ，３０Ｃが脱落する事態が招来されるおそれがない。さらに、それぞれの熱膨張性部材３０Ａ，３０Ｂ，３０Ｃに対して長手方向の一部のみを保持部材５０で保持するようにしているため、加熱された場合の発泡量に影響を与えるおそれがない。しかも、それぞれの熱膨張性部材３０Ａ，３０Ｂ，３０Ｃに対しては、上端部に保持部材５０を設けるようにしているため、縦框２４から垂れ下がるような事態となるおそれもない。これらの結果、火災発生時等において建具が高温状態に晒された場合には、縦框２４と縦枠１３との間が発泡した熱膨張性部材３０Ａ，３０Ｂ，３０Ｃによって塞がれることになり、室内外で貫通口が生じる事態を防止し、防火性を向上させることができるようになる。 Therefore, in the state where the holding member 50 is attached to the vertical rod 24, even if the adhesive state between the vertical rod 24 and the respective thermally expandable members 30A, 30B, 30C is released due to the influence of aging, the vertical There is no possibility of incurring a situation where the thermally expandable members 30A, 30B, and 30C are dropped from the flange 24. Furthermore, since only part of the longitudinal direction of each of the thermally expandable members 30A, 30B, and 30C is held by the holding member 50, there is no possibility of affecting the amount of foaming when heated. In addition, since the holding member 50 is provided at the upper end portion of each of the thermally expandable members 30A, 30B, and 30C, there is no possibility of a situation of hanging from the vertical rod 24. As a result, when the joinery is exposed to a high temperature in the event of a fire, the space between the vertical fence 24 and the vertical frame 13 is blocked by the foamed thermally expandable members 30A, 30B, 30C. Thus, it is possible to prevent the occurrence of a through-hole inside and outside the room and to improve the fire resistance.
加えて、一つの保持部材５０によって３つの熱膨張性部材３０Ａ，３０Ｂ，３０Ｃの脱落を防止することが可能であるため、取り扱い部品点数を増やすことなく、熱膨張性部材３０Ａ，３０Ｂ，３０Ｃの発泡量を増大させることが可能であり、製造コストが増大する事態を抑えることができる。さらに、互いに直交する方向に沿って延在する縦框２４の見込み面２４ｂと当接ヒレ部２４ａの室外に臨む見付け面２４ｃとに熱膨張性部材３０Ａ，３０Ｂ，３０Ｃを配設し、かつこれらの熱膨張性部材３０Ａ，３０Ｂ，３０Ｃの表面に対向する押え面部５３，５４，５５を有した保持部材５０を適用している。このため、単一のネジ６０を螺合した場合にも保持部材５０が不用意に回転することがなく、保持部材５０を容易に、かつ確実に縦框２４に取り付けることが可能となる。 In addition, since it is possible to prevent the three heat-expandable members 30A, 30B, and 30C from falling off by one holding member 50, the heat-expandable members 30A, 30B, and 30C can be prevented without increasing the number of handling parts. The amount of foaming can be increased, and the situation where the manufacturing cost increases can be suppressed. Furthermore, thermally expandable members 30A, 30B, and 30C are disposed on the prospective surface 24b of the vertical rod 24 extending along the directions orthogonal to each other and the finding surface 24c facing the outdoor side of the contact fin portion 24a, and The holding member 50 having the pressing surface portions 53, 54, 55 facing the surfaces of the thermally expandable members 30A, 30B, 30C is applied. For this reason, even when the single screw 60 is screwed, the holding member 50 does not rotate carelessly, and the holding member 50 can be easily and reliably attached to the vertical shaft 24.
なお、上述した実施の形態では、障子２０の縦框２４に配設した熱膨張性部材３０Ａ，３０Ｂ，３０Ｃについて例示しているが、必ずしも縦框２４に限らず、障子２０の上框２２や下框２３であっても良いし、枠体１０に熱膨張性部材を配設する場合にももちろん適用することが可能である。この場合、建具としては必ずしも内倒し窓である必要はなく、その他の建具にも同様に適用することが可能である。また、第１の熱膨張性部材３０Ａ及び第３の熱膨張性部材３０Ｃについては、２箇所に保持部材５０を設けるようにしているが、１つの熱膨張性部材に対して１つの保持部材が設けられていれば十分である。さらに、３つの熱膨張性部材３０Ａ，３０Ｂ，３０Ｃを同時に保持するように保持部材５０を構成しているが、複数であれば、３以外の数の熱膨張性部材を同時に保持するように保持部材を構成しても構わない。 In the above-described embodiment, the heat-expandable members 30A, 30B, and 30C disposed on the vertical shaft 24 of the shoji 20 are illustrated. The lower collar 23 may be used, and of course, the present invention can also be applied to the case where a thermally expandable member is disposed on the frame 10. In this case, the joinery does not necessarily need to be an inward-facing window, and can be similarly applied to other joinery. Moreover, about the 1st thermal expansible member 30A and the 3rd thermal expansible member 30C, although it is trying to provide the holding member 50 in two places, one holding member is with respect to one thermal expansible member. It is enough if it is provided. Further, the holding member 50 is configured to hold the three thermally expandable members 30A, 30B, and 30C at the same time. However, if there are a plurality of the thermally expandable members 30A, 30B, and 30C, the number of the thermally expandable members other than three is held at the same time. You may comprise a member.
例えば、図５の変形例１に示すように、フレーム材１００の単一の取付面１００ａに配設した２つの熱膨張性部材１３０Ａ，１３０Ｂを保持対象とし、並設された２つの押え面部１５１，１５２を有するように保持部材１５０を構成し、これをネジ１６０によってフレーム材１００に取り付けても良い。また、図６の変形例２に示すように、フレーム材２００の互いに平行となる２つの取付面２００ａ，２００ｂに配設した２つの熱膨張性部材２３０Ａ，２３０Ｂを保持対象とし、互いに平行となる２つの押え面部２５１，２５２を有した保持部材２５０をネジ２６０によってフレーム材２００に取り付けることも可能である。なお、図５の変形例１においては、実施の形態と同一形状の保持部材１５０を適用しているが、必ずしも第３の押え面部に相当する部分１５３を有している必要はない。仮に、変形例１の保持部材１５０に第３の押え面部に相当する部分１５３が設けられていないとしても、段部１５４が熱膨張性部材１３０Ａ，１３０Ｂの側面１３１に対向しているため、単一のネジ１６０を螺合する際に、段部１５４が熱膨張性部材１３０Ａ，１３０Ｂの側面１３１に当接することで保持部材１５０の不用意な回転が規制されることになる。従って、保持部材１５０を取り付ける際には実施の形態とほぼ同等の作業性を確保することが可能である。 For example, as shown in Modification 1 in FIG. 5, two pressing surface portions 151 arranged in parallel with two thermally expandable members 130 </ b> A and 130 </ b> B disposed on a single mounting surface 100 a of the frame material 100 as holding targets. , 152 may be configured to be attached to the frame member 100 with screws 160. Further, as shown in Modification 2 of FIG. 6, the two thermally expandable members 230A and 230B disposed on the two mounting surfaces 200a and 200b that are parallel to each other of the frame member 200 are to be held and are parallel to each other. It is also possible to attach the holding member 250 having the two pressing surface portions 251 and 252 to the frame material 200 with screws 260. In Modification 1 of FIG. 5, the holding member 150 having the same shape as that of the embodiment is applied, but it is not always necessary to have the portion 153 corresponding to the third pressing surface portion. Even if the holding member 150 of Modification 1 is not provided with the portion 153 corresponding to the third pressing surface portion, the step portion 154 faces the side surface 131 of the thermally expandable members 130A and 130B. When one screw 160 is screwed, the stepped portion 154 comes into contact with the side surfaces 131 of the thermally expandable members 130A and 130B, so that inadvertent rotation of the holding member 150 is restricted. Therefore, when attaching the holding member 150, it is possible to ensure workability substantially equivalent to the embodiment.
また、図７の変形例３に示すように、フレーム材３００の表面３００ａに凹部３００ｂを有し、この凹部３００ｂに配置された第１の熱膨張性部材３３０Ａを保持対象とするように保持部材３５０を構成することも可能である。すなわち、変形例３の保持部材３５０は、フレーム材３００の表面３００ａに当接する当接面部３５１と、当接面部３５１の縁部から凹部３００ｂに進入するように設けられた段部３５２と、段部３５２の延在端部に設けた第１の押え面部３５３とを有したものである。さらに、図示の例では、フレーム材３００の表面３００ａに対して直交する方向に突出したヒレ部３０１の表面３０１ａに第２の熱膨張性部材３３０Ｂが配置されており、この第２の熱膨張性部材３３０Ｂに対向するように保持部材３５０に第２の押え面部３５４が設けてある。この保持部材３５０の当接面部３５１をネジ３６０によってフレーム材３００の表面３００ａに取り付ければ、第２の押え面部３５４によって第２の熱膨張性部材３３０Ｂが保持されるとともに、凹部３００ｂに進入する第１の押え面部３５３によって第１の熱膨張性部材３３０Ａも保持されることになる。 Further, as shown in Modification 3 in FIG. 7, the holding member is configured so that the surface 300 a of the frame member 300 has a recess 300 b and the first thermally expandable member 330 </ b> A disposed in the recess 300 b is a holding target. It is also possible to configure 350. That is, the holding member 350 of Modification 3 includes a contact surface portion 351 that contacts the surface 300a of the frame member 300, a step portion 352 that is provided so as to enter the recess 300b from an edge portion of the contact surface portion 351, and a step. And a first pressing surface portion 353 provided at the extending end of the portion 352. Further, in the illustrated example, the second thermally expandable member 330B is disposed on the surface 301a of the fin portion 301 protruding in a direction orthogonal to the surface 300a of the frame member 300, and this second thermally expandable member. A second pressing surface portion 354 is provided on the holding member 350 so as to face the member 330B. When the contact surface portion 351 of the holding member 350 is attached to the surface 300a of the frame member 300 with the screw 360, the second heat-expandable member 330B is held by the second pressing surface portion 354 and the second heat-expanding member 330B enters the recess 300b. The first heat-expandable member 330A is also held by the one pressing surface portion 353.
さらに、図８の変形例４に示すように、２つの熱膨張性部材４３０Ａ，４３０Ｂのうちの一方４３０Ａに直接ネジ４６０を挿通させて保持部材４５０をフレーム材４００に取り付けるようにしても良い。この変形例４によれば、保持部材４５０としては、当接面部や段部を設けることなく、単に２つの押え面部４５１，４５２がほぼ直角となるように連結された単純形状のものを適用することが可能である。 Further, as shown in Modification 4 in FIG. 8, the holding member 450 may be attached to the frame member 400 by inserting a screw 460 directly into one of the two thermally expandable members 430 </ b> A and 430 </ b> B. According to the fourth modification, as the holding member 450, one having a simple shape in which the two pressing surface portions 451 and 452 are connected so as to be substantially perpendicular is applied without providing the contact surface portion or the step portion. It is possible.
なお、上述した実施の形態及び変形例１〜変形例４では、いずれも単一のネジを螺合することによって保持部材をフレーム材に取り付けるようにしているが、保持部材を取り付けるネジの数は一つでなくても良い。この場合には、保持部材の２つの押え面部が互いに交差するように延在している必要はなく、また保持部材が段部を有している必要もない。つまり、単に平板状を成す保持部材を適用することも可能である。また、保持部材としては、必ずしも金属製のものを適用する必要はなく、樹脂によって成形したものを適用しても構わない。 In the above-described embodiment and Modifications 1 to 4, the holding member is attached to the frame material by screwing a single screw, but the number of screws to which the holding member is attached is It doesn't have to be one. In this case, the two pressing surface portions of the holding member do not need to extend so as to cross each other, and the holding member does not need to have a stepped portion. That is, it is also possible to apply a holding member having a flat plate shape. Moreover, as a holding member, it is not always necessary to apply a metal member, and a member formed of a resin may be applied.
