Description

本発明は外装材の取付具及び建物の外装構造に関する。   The present invention relates to a fixture for exterior materials and an exterior structure of a building.

特許文献１、２に従来の外装材の取付具が開示されている。特許文献１、２の取付具は、四方合い決り構造の外装材に用いるためのものである。各取付具は、構造体に固定される固定部、固定部から突出する支承片、支承片に上方に向けて設けられる上係止片、及び支承片に下方に向けて設けられる下係止片を備えている。支承片は、上側に位置する２枚の外装材を支承する。上係止片は、上側に位置する２枚の外装材を係止する。下係止片は、下側に位置する２枚の外装材を係止する。   Patent Literatures 1 and 2 disclose conventional mounting materials for exterior materials. The attachments of Patent Literatures 1 and 2 are for use as an exterior material having a four-way mating structure. Each of the attachments includes a fixing portion fixed to the structure, a support piece protruding from the fixing portion, an upper locking piece provided on the support piece upward, and a lower locking piece provided on the support piece downward.

特開２００２−２２０９１０号公報JP-A-2002-220910 特開２００２−８１１８６号公報JP 2002-81186 A

ところで、特許文献１に開示の取付具では、固定部の幅方向の中心線に最も近い貫通孔が中心線上に配置されている一方、立設片が中心線から幅方向にずれて配置されている。このため、各外装材の荷重を支承片、上係止片及び下係止片が支持する際、幅方向の一方に位置する２枚の外装材を支持する長さと、幅方向の他方に位置する２枚の外装材を支持する長さとが等しくならず、それらの荷重バランスが幅方向の一方と他方とで均等になり難い。   By the way, in the fixture disclosed in Patent Literature 1, the through-hole closest to the center line in the width direction of the fixing portion is arranged on the center line, while the standing piece is arranged to be shifted from the center line in the width direction. I have. For this reason, when the bearing piece, the upper locking piece, and the lower locking piece support the load of each exterior material, the length supporting the two exterior materials located on one side in the width direction and the position on the other side in the width direction. Therefore, the lengths for supporting the two exterior materials are not equal, and it is difficult for the load balance between them to be equal between the one and the other in the width direction.

この点、特許文献２に開示の取付具では、固定部の幅方向の中心線に最も近い貫通孔が中心線上に配置され、立設片も中心線上に配置されている。このため、各外装材の荷重を支承片、上係止片及び下係止片が支持する際、幅方向の一方に位置する２枚の外装材を支持する長さと、幅方向の他方に位置する２枚の外装材を支持する長さとが等しくなり、それらの荷重バランスを幅方向の一方と他方とで均等にできる。   In this regard, in the fixture disclosed in Patent Literature 2, the through-hole closest to the center line in the width direction of the fixing portion is arranged on the center line, and the standing pieces are also arranged on the center line. For this reason, when the bearing piece, the upper locking piece, and the lower locking piece support the load of each exterior material, the length supporting the two exterior materials located on one side in the width direction and the position on the other side in the width direction. Therefore, the length of supporting the two exterior materials becomes equal, and the load balance between them can be made uniform between one and the other in the width direction.

しかしながら、この取付具では、細い構造部材に取付具を固定する場合において、下側の２枚の外装材の表面同士の突合せラインが構造部材の中央付近に位置するように取付具を構造部材に固定しようとすると、固定部の幅方向の中心線上に配置された立設片が構造部材の側面の近傍に配置され易くなる。それに伴って、中心線上に配置された貫通孔も、その構造部材の側面の近傍に配置され易くなる。すると、中心線上に配置された貫通孔に挿通される釘やネジ等の締結具が構造部材の側面から突き出したり、構造部材の側面が割れてしまったりする等の不具合が生じるおそれがある。   However, in this fixture, when the fixture is fixed to a thin structural member, the fixture is attached to the structural member such that the butting line between the surfaces of the two lower exterior members is located near the center of the structural member. When the fixing member is to be fixed, the standing piece arranged on the center line in the width direction of the fixing portion is easily arranged near the side surface of the structural member. Accordingly, the through holes arranged on the center line are also easily arranged near the side surfaces of the structural member. Then, there is a possibility that a fastener such as a nail or a screw inserted into the through-hole disposed on the center line may protrude from the side surface of the structural member, or the side surface of the structural member may be broken.

つまり、上記従来の取付具では、各外装材の荷重を幅方向においてバランスよく支持することと、細い構造部材に固定される際に良好な施工性を発揮することを共に実現することが難しい。   In other words, it is difficult for the above-mentioned conventional mounting tool to both support the load of each exterior material in the width direction in a well-balanced manner and exhibit good workability when fixed to a thin structural member.

本発明は、上記従来の実情に鑑みてなされたものであって、各外装材の荷重を幅方向においてバランスよく支持できるとともに、細い構造部材に固定される場合でも良好な施工性を発揮することができる外装材の取付具及び建物の外装構造を提供することを解決すべき課題としている。   The present invention has been made in view of the above-described conventional circumstances, and can support the load of each exterior material in a balanced manner in the width direction and exhibit good workability even when fixed to a thin structural member. It is an object of the present invention to provide an exterior material fixture and a building exterior structure that can be used.

本発明の第１の態様として外装材の取付具は、第１外装材と、前記第１外装材に対して上方から隣接する第２外装材と、前記第１外装材に対して水平方向の一方から隣接する第３外装材と、前記第３外装材に対して上方から隣接し、かつ、前記第２外装材に対して水平方向の一方から隣接する第４外装材とを、建物を構成する構造体に対して取り付けるための取付具であって、
基準面を有し、前記基準面を介して前記構造体に固定される固定部と、
前記固定部に締結具を挿通するための少なくとも１つの固定孔と、
前記固定部から突出し、前記第２外装材及び前記第４外装材を支承する支承片と、
前記支承片に上方に向けて設けられ、前記第２外装材及び前記第４外装材を係止する上係止片と、
前記支承片に下方に向けて設けられ、前記第１外装材及び前記第３外装材を係止する下係止片と、
前記固定部から突出し、前記第１外装材及び前記第３外装材の対向する端部同士の間に配置される立設片と、を備え、
前記立設片は、前記固定部の幅方向の中心線上に配置され、
前記固定孔のうちの前記中心線に最も近い特定固定孔は、前記中心線に対して前記幅方向の一方にずれた位置に配置され、
前記固定孔は、前記中心線に対して非対称に配置されることを特徴とする。 As a first aspect of the present invention, a fixture for an exterior material includes a first exterior material, a second exterior material adjacent to the first exterior material from above, and a horizontal direction with respect to the first exterior material. A building is constituted by a third exterior material adjacent from one side and a fourth exterior material adjacent to the third exterior material from above and adjacent to the second exterior material from one side in a horizontal direction. A fixture for attaching to a structure to be
A fixing portion having a reference surface and fixed to the structure via the reference surface;
At least one fixing hole for inserting a fastener through the fixing portion,
A support piece projecting from the fixing portion and supporting the second exterior material and the fourth exterior material;
An upper locking piece that is provided upward on the bearing piece and locks the second exterior material and the fourth exterior material;
A lower locking piece that is provided downward on the bearing piece and locks the first exterior material and the third exterior material;
A standing piece protruding from the fixing portion and disposed between opposed ends of the first exterior material and the third exterior material,
The standing piece is disposed on a center line in the width direction of the fixing portion,
The specific fixing hole closest to the center line among the fixing holes is arranged at a position shifted in the width direction with respect to the center line,
The fixing holes are arranged asymmetrically with respect to the center line.

本発明の第１の態様として外装材の取付具では、立設片が固定部の幅方向の中心線上に配置されている。このため、支承片、上係止片及び下係止片が第１〜４外装材の荷重を支持する際、幅方向の一方に位置する第１、２外装材を支持する長さと、幅方向の他方に位置する第３、４外装材を支持する長さとが等しくなり、それらの荷重バランスを幅方向の一方と他方とで均等にできる。また、この取付具において、固定孔のうちの中心線に最も近い特定固定孔は、中心線に対して幅方向の一方にずれている。このため、細い構造部材に取付具を固定する場合において、第１、３外装材の表面同士の突合せラインが構造部材の中央付近に位置するように取付具を構造部材に固定しても、特定固定孔がその構造部材の側面の近傍に配置され難くなる。その結果、特定固定孔に挿通される締結具が構造部材の側面から突き出したり、構造部材の側面が割れてしまったりする等の不具合を防止できる。また、特定固定孔以外の固定孔についても、特定固定孔と同様に幅方向にずらして配置できる。このため、それらの固定孔が構造部材の側面の近傍に配置されることを抑制できる。このため、それらの固定孔に挿通される締結具が構造部材の側面から突き出したり、構造部材の側面が割れてしまったりする等の不具合を防止できる。   As a first aspect of the present invention, in the fixture for an exterior material, the standing pieces are arranged on the center line in the width direction of the fixing portion. For this reason, when the support piece, the upper locking piece, and the lower locking piece support the load of the first to fourth exterior materials, the length supporting the first and second exterior materials located on one side in the width direction and the width direction And the lengths supporting the third and fourth exterior materials located on the other side are equal, and the load balance between them can be made uniform between one side and the other in the width direction. In this attachment, the specific fixing hole closest to the center line among the fixing holes is shifted to one side in the width direction with respect to the center line. For this reason, even when the fixture is fixed to the thin structural member, even if the fixture is fixed to the structural member so that the butting line between the surfaces of the first and third exterior members is located near the center of the structural member, the specific It becomes difficult to dispose the fixing hole near the side surface of the structural member. As a result, it is possible to prevent such a problem that the fastener inserted into the specific fixing hole protrudes from the side surface of the structural member, or the side surface of the structural member is broken. Further, the fixing holes other than the specific fixing holes can be displaced in the width direction similarly to the specific fixing holes. For this reason, it can control that those fixing holes are arranged near the side of a structural member. For this reason, it is possible to prevent problems such as the fasteners inserted into the fixing holes protruding from the side surfaces of the structural member and the side surfaces of the structural member being cracked.

したがって、本発明の第１の態様として外装材の取付具では、各外装材の荷重を幅方向においてバランスよく支持できるとともに、細い構造部材に固定される場合でも良好な施工性を発揮することができる。   Therefore, as the first aspect of the present invention, in the fixture for the exterior material, it is possible to support the load of each exterior material in a balanced manner in the width direction, and to exhibit good workability even when fixed to a thin structural member. it can.

本発明の第２の態様として、各外装材における水平方向の一端部は、外装材の表面から裏面に向かって凹み、垂直方向に延在する裏側左右接合部を有していることが望ましい。また、各外装材における水平方向の他端部は、外装材の裏面から表面に向かって凹み、垂直方向に延在する表側左右接合部を有していることが望ましい。この構成によれば、第１外装材の裏側左右接合部と、第３外装材の表側左右接合部とは、中心線に対して幅方向の一方にずれた位置で重なり合う。換言すると、特定固定孔は、裏側左右接合部と表側左右接合部とが重なり合う範囲内、又はその重なり合う範囲の近傍に配置される。このため、細い構造部材に取付具を固定する場合において、第１、３外装材の表面同士の突合せラインが構造部材の中央付近に位置するように取付具を構造部材に固定しても、特定固定孔がその構造部材の側面の近傍に配置され難くなる。その結果、この取付具では、良好な施工性を一層発揮することができる。   As a second aspect of the present invention, it is desirable that one end in the horizontal direction of each exterior material has a back-side left / right joint that extends vertically from the surface of the exterior material. Further, it is desirable that the other end in the horizontal direction of each exterior material has a front-side left / right joint that is recessed from the back surface to the front surface and extends vertically. According to this configuration, the back left / right joint of the first exterior material and the front left / right junction of the third exterior material overlap at a position shifted to one side in the width direction with respect to the center line. In other words, the specific fixing hole is disposed in a range where the rear left / right joint and the front left / right joint overlap, or in the vicinity of the overlapping range. For this reason, even when the fixture is fixed to the thin structural member, even if the fixture is fixed to the structural member so that the butting line between the surfaces of the first and third exterior members is located near the center of the structural member, the specific It becomes difficult to dispose the fixing hole near the side surface of the structural member. As a result, with this mounting tool, good workability can be further exhibited.

本発明の第３の態様として、特定固定孔が中心線に対してずれる距離は、裏側左右接合部及び表側左右接合部の重なり幅の１／４以上、かつ重なり幅の３／４以下に設定されていることが望ましい。この構成によれば、特定固定孔が細い構造部材の側面の近傍に一層配置され難くなる。その結果、この取付具では、良好な施工性をより一層発揮することができる。   As a third aspect of the present invention, the distance by which the specific fixing hole is displaced from the center line is set to be equal to or more than 1/4 of the overlap width of the back left / right joint and the front right / left joint and not more than 3/4 of the overlap width. It is desirable to have been. According to this configuration, it is more difficult for the specific fixing hole to be further arranged near the side surface of the thin structural member. As a result, with this attachment, good workability can be further exhibited.

本発明の第４の態様として、特定固定孔は、垂直方向に複数並んで設けられていることが望ましい。この構成によれば、垂直方向に複数並ぶ特定固定孔により、取付具を構造部材に一層強固に固定することができる。特に取付具の回転を防止できる。   As a fourth aspect of the present invention, it is preferable that a plurality of the specific fixing holes are provided in a vertical direction.

ここで、図５、図６及び図１４〜図１８に示すように、各外壁板２のうちの任意の１枚の外壁板２を第１外壁板２Ａ１とし、第１外壁板２Ａ１に対して以下の関係にある３枚の外壁板２を第２外壁板２Ａ２、第３外壁板２Ａ３及び第４外壁板２Ａ４とする。第２外壁板２Ａ２は、第１外壁板２Ａ１に対して上方から隣接している。第３外壁板２Ａ３は、第１外壁板２Ａ１に対して右方から隣接している。第４外壁板２Ａ４は、第３外壁板２Ａ３に対して上方から隣接し、かつ、第２外壁板２Ａ２に対して右方から隣接している。   Here, as shown in FIGS. 5, 6, and 14 to 18, any one of the outer wall boards 2 is defined as a first outer wall board 2 </ b> A <b> 1, and with respect to the first outer wall board 2 </ b> A <b> 1. The three outer wall boards 2 having the following relationship are referred to as a second outer wall board 2A2, a third outer wall board 2A3, and a fourth outer wall board 2A4. The second outer wall plate 2A2 is adjacent to the first outer wall plate 2A1 from above. The third outer wall plate 2A3 is adjacent to the first outer wall plate 2A1 from the right. The fourth outer wall plate 2A4 is adjacent to the third outer wall plate 2A3 from above, and is adjacent to the second outer wall plate 2A2 from the right.

このような構成である各外壁板２は、以下のようにして、各取付具１０に支持される。   Each outer wall plate 2 having such a configuration is supported by each fixture 10 as follows.

図１に示すように、初めに、構造体８の外面８Ｆの最も下方の位置に、複数の外壁板２を左右方向に隣接させた状態で取り付ける。この際、それらの外壁板２における下端部２Ｄは、構造体８の外面８Ｆの最下部に配置されて左右方向に延びる下端支持部材５５に係止される。左右方向に隣接する外壁板２を第１外壁板２Ａ１及び第３外壁板２Ａ３とする。   As shown in FIG. 1, first, a plurality of outer wall plates 2 are attached to the lowermost position of the outer surface 8F of the structure 8 in a state where the outer wall plates 2 are adjacent to each other in the left-right direction. At this time, the lower end portions 2D of the outer wall plates 2 are engaged with lower end support members 55 which are arranged at the lowermost portion of the outer surface 8F of the structure 8 and extend in the left-right direction. The outer wall boards 2 adjacent in the left-right direction are referred to as a first outer wall board 2A1 and a third outer wall board 2A3.

次に、図１４に示すように、取付具１０の基準面１５Ｓを柱材９に当接させながら、取付具１０を下方に移動させ、第１、３外壁板２Ａ１、２Ａ３の左右接合部２６に、取付具１０の立設片１９を上方から挿入する。そして、図１５及び図１７に示すように、ネジ１０ＢをＵ字状固定部１５Ｂの固定孔１５Ｈに挿通し、柱材９にねじ込むことにより、取付具１０は、柱材９に固定された固定状態となる。ネジ１０Ｂの頭部は、上膨出部３８によって、取付具１０の表側に突出しない。   Next, as shown in FIG. 14, the fixture 10 is moved downward while the reference surface 15S of the fixture 10 is in contact with the column member 9, and the left and right joints 26 of the first and third outer wall plates 2A1, 2A3 are moved. Then, the standing piece 19 of the fixture 10 is inserted from above. Then, as shown in FIGS. 15 and 17, the screw 10 </ b> B is inserted into the fixing hole 15 </ b> H of the U-shaped fixing portion 15 </ b> B and screwed into the column 9, so that the fixture 10 is fixed to the column 9. State. The head of the screw 10 </ b> B does not protrude to the front side of the fixture 10 due to the upper bulging portion 38.

これにより、第１、３外壁板２Ａ１、２Ａ３の裏側上下接合部２４の係合凸部２４Ａは、取付具１０の下係止片１２によって係止される。また、第１、３外壁板２Ａ１、２Ａ３のそれぞれの裏面２Ｂは、取付具１０の当接面３１によって、より詳しくは、下方の横長面３１Ｄ及び左右の縦長面３１Ｌ、３１Ｒの下部分によって、支持される。これにより、第１、３外壁板２Ａ１、２Ａ３は、屋内方向に向かって位置ずれしないように規制される。その結果、図１７及び図１８に示すように、構造体８と第１、３外壁板２Ａ１、２Ａ３の裏面２Ｂとの間に、通気空間Ｓ１が確保される。   As a result, the engaging projections 24A of the rear upper and lower joints 24 of the first and third outer wall plates 2A1, 2A3 are locked by the lower locking pieces 12 of the fixture 10. Also, the back surface 2B of each of the first and third outer wall plates 2A1, 2A3 is formed by the contact surface 31 of the fixture 10, more specifically, by the lower part of the lower horizontal surface 31D and the lower part of the left and right vertical surfaces 31L, 31R. Supported. Accordingly, the first and third outer wall plates 2A1, 2A3 are regulated so as not to be displaced toward the indoor direction. As a result, as shown in FIGS. 17 and 18, the ventilation space S1 is secured between the structure 8 and the back surface 2B of the first and third outer wall plates 2A1, 2A3.

こうして、取付具１０は、固定状態において、第１、３外壁板２Ａ１、２Ａ３の上端部２Ｕを支持する。また、取付具１０の立設片１９は、固定状態において、第１、３外壁板２Ａ１、２Ａ３の水平方向において対向する端部同士の間に配置され、第１、３外壁板２Ａ１、２Ａ３の横ズレを防止する。図１７に示すように、第１外壁板２Ａ１の裏側左右接合部２２と、第３外壁板２Ａ３の表側左右接合部２１とは、固定部１５の中心線Ｃ１上に配置された立設片１９に対して左方にずれた位置で重なり合う。   Thus, the fixture 10 supports the upper end 2U of the first and third outer wall plates 2A1, 2A3 in the fixed state. In the fixed state, the standing piece 19 of the attachment 10 is disposed between the horizontally opposed ends of the first and third outer wall plates 2A1 and 2A3, and the first and third outer wall plates 2A1 and 2A3 Prevent lateral misalignment. As shown in FIG. 17, the rear left / right joint 22 of the first outer wall plate 2A1 and the front left / right joint 21 of the third outer wall plate 2A3 are erected pieces 19 arranged on the center line C1 of the fixing portion 15. Overlap at a position shifted to the left with respect to.

次に、図１６及び図１８に示すように、第１、３外壁板２Ａ１、２Ａ３の上方に、第２、４外壁板２Ａ２、２Ａ４を左右方向に隣接させた状態で取り付ける。   Next, as shown in FIGS. 16 and 18, the second and fourth outer wall plates 2A2 and 2A4 are attached above the first and third outer wall plates 2A1 and 2A3 in a state where they are adjacent to each other in the left-right direction.

これにより、第２、４外壁板２Ａ２、２Ａ４の表側上下接合部２３の係合凹部２３Ａは、取付具１０の上係止片１１Ｌ、１１Ｒによって係止される。   As a result, the engagement recesses 23A of the front side upper and lower joints 23 of the second and fourth outer wall plates 2A2 and 2A4 are locked by the upper locking pieces 11L and 11R of the fixture 10.

この際、図１１、図１２、図１６及び図１８に示すように、突起部１７Ｃ、１７Ｌ、１７Ｒは、第２、４外壁板２Ａ２、２Ａ４の端面に下方から接触し、支承片１３と第２、４外壁板２Ａ２、２Ａ４との間に、図１１及び図１２に示す隙間Ｗ１を確保する。ここで、突起部１７Ｃ、１７Ｌ、１７Ｒと第２、４外壁板２Ａ２、２Ａ４の端面とが接触する面積は、支承片１３と第２、４外壁板２Ａ２、２Ａ４の端面とが仮に突起部１７Ｃ、１７Ｌ、１７Ｒ無しで直に接触する場合の面積よりも小さくなる。このため、支承片１３上に溜まった雨水や、支承片１３上のゴミや塵等が吸い込んだ雨水が長時間にわたり第２、４外壁板２Ａ２、２Ａ４の端面に接触することを抑制でき、ひいては、雨水等がしみこんで第２、４外壁板２Ａ２、２Ａ４が損傷することを防止できる。   At this time, as shown in FIGS. 11, 12, 16, and 18, the projections 17C, 17L, and 17R come into contact with the end surfaces of the second and fourth outer wall plates 2A2 and 2A4 from below, and A gap W1 shown in FIGS. 11 and 12 is secured between the second and fourth outer wall plates 2A2 and 2A4. Here, the area where the projections 17C, 17L, 17R are in contact with the end faces of the second and fourth outer wall plates 2A2, 2A4 is such that the bearing piece 13 and the end faces of the second and fourth outer wall plates 2A2, 2A4 are temporarily formed as projections 17C. , 17L, 17R are smaller than the area in the case of direct contact. For this reason, it is possible to prevent rainwater accumulated on the bearing piece 13 and rainwater sucked by dust and dirt on the bearing piece 13 from contacting the end faces of the second and fourth outer wall plates 2A2 and 2A4 for a long time, and thus, The second and fourth outer wall plates 2A2 and 2A4 can be prevented from being damaged by rainwater or the like.

また、図１８に示すように、上係止片１１Ｌに隣接する弾性体１８は、第２外壁板２Ａ２の下端に当接して圧縮変形する。図示は省略するが、上係止片１１Ｒに隣接する弾性体１８も同様に、第４外壁板２Ａ４の下端に当接して圧縮変形する。このような左右の弾性体１８により、第２外壁板２Ａ２と支承片１３との間、及び第４外壁板２Ａ４と支承片１３との間がシールされる。   As shown in FIG. 18, the elastic body 18 adjacent to the upper locking piece 11L abuts on the lower end of the second outer wall plate 2A2 and is compressed and deformed. Although not shown, the elastic body 18 adjacent to the upper locking piece 11R also similarly abuts on the lower end of the fourth outer wall plate 2A4 and is compressed and deformed. The left and right elastic members 18 seal the space between the second outer wall plate 2A2 and the support piece 13 and the space between the fourth outer wall plate 2A4 and the support piece 13.

また、第２、４外壁板２Ａ２、２Ａ４のそれぞれの裏面２Ｂは、取付具１０の当接面３１によって、より詳しくは、上方の横長面３１Ｕ及び左右の縦長面３１Ｌ、３１Ｒの上部分によって、支持される。これにより、第２、４外壁板２Ａ２、２Ａ４は、屋内方向に向かって位置ずれしないように規制される。その結果、構造体８と第２、４外壁板２Ａ２、２Ａ４の裏面２Ｂとの間に、通気空間Ｓ１が確保される。   In addition, the back surface 2B of each of the second and fourth outer wall plates 2A2 and 2A4 is formed by the contact surface 31 of the fixture 10, more specifically, by the upper portion of the horizontally long surface 31U and the upper portions of the left and right vertically long surfaces 31L and 31R. Supported. Thereby, the second and fourth outer wall plates 2A2 and 2A4 are regulated so as not to be displaced toward the indoor direction. As a result, a ventilation space S1 is secured between the structure 8 and the back surface 2B of the second and fourth outer wall plates 2A2, 2A4.

図１５〜図１８では、各特定固定孔１５Ｔにネジ１０Ｂを挿入し、柱材９にねじ込むことにより、取付具１０を柱材９に固定する例を図示しているが、柱材９の横幅が取付具１０の横幅よりも大きいので、他の固定孔１５Ｈにネジ１０Ｂを挿入して、取付具１０を柱材９に固定することもできる。   FIGS. 15 to 18 illustrate an example in which the screws 10 </ b> B are inserted into the specific fixing holes 15 </ b> T and screwed into the column members 9, thereby fixing the fixture 10 to the column members 9. Is larger than the lateral width of the fixture 10, the screw 10 </ b> B can be inserted into another fixing hole 15 </ b> H to fix the fixture 10 to the column 9.

その一方、図１９に示すように、取付具１０を細い構造部材９９に固定する場合がある。そして、細い構造部材９９の横幅Ｗ９９が図８に示す距離ＬＧ２＋ＬＧ３に近い長さであるか、又は距離ＬＧ２＋ＬＧ３以下の長さであると、各特定固定孔１５Ｔ以外の固定孔１５Ｈが細い構造部材９９からはみ出し易い。このため、取付具１０を細い構造部材９９に固定するために、各特定固定孔１５Ｔのみを使用することになる。   On the other hand, as shown in FIG. 19, the attachment 10 may be fixed to a thin structural member 99. When the width W99 of the narrow structural member 99 is a length close to the distance LG2 + LG3 shown in FIG. 8 or is equal to or shorter than the distance LG2 + LG3, the fixing holes 15H other than the specific fixing holes 15T are thin. It is easy to stick out. For this reason, in order to fix the fixture 10 to the thin structural member 99, only the specific fixing holes 15T are used.

ここで、図１９に示すように、施工品質上、第１、３外壁板２Ａ１、２Ａ３の表面２Ｆ同士の突合せラインＪ１を細い構造部材９９の中央付近に位置させるように、取付具１０を細い構造部材９９に固定することが好ましい。この点、図８に示すように、特定固定孔１５Ｔが中心線Ｃ１に対して左方に距離ＬＧ１（ＷＬ１×１／４≦ＬＧ１≦ＷＬ１×３／４）ずれた位置に配置され、立設片１９が中心線Ｃ１上に配置されている。このため、上記の施工作業を行って、取付具１０が細い構造部材９９に固定されると、特定固定孔１５Ｔが細い構造部材９９の中央付近に配置され、細い構造部材９９の側面９９Ａの近傍に配置され難くなる。   Here, as shown in FIG. 19, in terms of construction quality, the fitting 10 is thin so that the butting line J1 between the surfaces 2F of the first and third outer wall plates 2A1 and 2A3 is located near the center of the thin structural member 99. It is preferable to fix to the structural member 99. In this regard, as shown in FIG. 8, the specific fixing hole 15T is disposed at a position shifted leftward from the center line C1 by a distance LG1 (WL1 × １ ／ ≦ LG1 ≦ WL1 × 3/4), and is erected. The piece 19 is arranged on the center line C1. For this reason, when the above-mentioned construction work is performed and the fixture 10 is fixed to the thin structural member 99, the specific fixing hole 15T is arranged near the center of the thin structural member 99, and near the side surface 99A of the thin structural member 99. Will be difficult to place.

こうして、取付具１０は、固定状態において、第２、４外壁板２Ａ２、２Ａ４を支持する。図示は省略するが、第２、４外壁板２Ａ２、２Ａ４の上端部２Ｕは、別の取付具１０によって、上述した手順で柱材９等に支持される。このような作業を他の外壁板２についても実施することにより、各外壁板２は、水平方向及び垂直方向に隣接する状態で、各柱材９等に支持され、構造体８の外面８Ｆを覆う。   Thus, the fixture 10 supports the second and fourth outer wall plates 2A2 and 2A4 in the fixed state. Although not shown, the upper ends 2U of the second and fourth outer wall plates 2A2 and 2A4 are supported by the column members 9 and the like by another fitting 10 in the above-described procedure. By performing such a work on other outer wall boards 2, each outer wall board 2 is supported by each column member 9 and the like in a state of being adjacent in the horizontal direction and the vertical direction, and the outer surface 8F of the structure 8 is cover.

なお、図６において、左右方向に並ぶ任意の２つの取付具１０の間に、追加的に他の取付具を配置して、垂直方向に隣接する外壁板２同士の上下接合部２５（第１、２外壁板２Ａ１、２Ａ２の上下接合部２５、及び第３、４外壁板２Ａ３、２Ａ４の上下接合部２５）をより強固に支持させてもよい。   In FIG. 6, another fitting is additionally arranged between any two fittings 10 arranged in the left-right direction, and the upper and lower joints 25 (the first joints 25) of the vertically adjacent outer wall plates 2 are arranged. The upper and lower joints 25 of the second outer wall plates 2A1 and 2A2 and the upper and lower joints 25 of the third and fourth outer wall plates 2A3 and 2A4 may be more strongly supported.

＜作用効果＞
実施の形態の取付具１０では、図８及び図１７等に示すように、立設片１９が固定部１５の幅方向の中心線Ｃ１上に配置されていることから、支承片１３、上係止片１１Ｌ、１１Ｒ及び下係止片１２が第１〜４外壁板２Ａ１〜２Ａ４の荷重を支持する際、幅方向の一方に位置する第１、２外壁板２Ａ１、２Ａ２を支持する長さと、幅方向の他方に位置する第３、４外壁板２Ａ３、２Ａ４を支持する長さとが等しくなり、それらの荷重バランスを幅方向の一方と他方とで均等にできる。 <Effects>
In the fixture 10 according to the embodiment, as shown in FIGS. 8 and 17 and the like, the upstanding piece 19 is disposed on the center line C1 in the width direction of the fixing portion 15, so that the support piece 13 and the upper When the stopper pieces 11L, 11R and the lower locking piece 12 support the load of the first to fourth outer wall boards 2A1 to 2A4, the length supporting the first and second outer wall boards 2A1, 2A2 located on one side in the width direction, The length supporting the third and fourth outer wall plates 2A3, 2A4 located on the other side in the width direction becomes equal, and the load balance between them can be made uniform between one side and the other side in the width direction.

また、この取付具１０において、図８等に示すように、複数の固定孔１５Ｈのうちの中心線Ｃ１に最も近い２つの特定固定孔１５Ｔは、固定部１５の中心線Ｃ１上に配置された立設片１９に対して左方にずれている。このため、図１９に示すように、第１、３外壁板２Ａ１、２Ａ３の表面２Ｆ同士の突合せラインＪ１が細い構造部材９９の中央付近に位置するように取付具１０を細い構造部材９９に固定しても、各特定固定孔１５Ｔが細い構造部材９９の側面９９Ａの近傍に配置され難くなる。その結果、各特定固定孔１５Ｔに挿通されるネジ１０Ｂが細い構造部材９９の側面９９Ａから突き出したり、細い構造部材９９の側面９９Ａが割れてしまったりする等の不具合を防止できる。また、図８等に示すように、各特定固定孔１５Ｔ以外の固定孔１５Ｈについても、各特定固定孔１５Ｔと同様に、中心線Ｃ１に対して幅方向にずらして配置されている。このため、図１７に示すように、第１、３外壁板２Ａ１、２Ａ３の表面２Ｆ同士の突合せラインＪ１が柱材９の中央付近に位置するように取付具１０を柱材９に固定しても、それらの固定孔１５Ｈが柱材９の側面９Ａの近傍に配置されることを抑制できる。このため、それらの固定孔１５Ｈに挿通されるネジ１０Ｂが柱材９及び細い構造部材９９の側面９Ａ、９９Ａから突き出したり、柱材９及び細い構造部材９９の側面９Ａ、９９Ａが割れてしまったりする等の不具合を防止できる。   In addition, in the attachment 10, as shown in FIG. 8 and the like, two specific fixing holes 15T closest to the center line C1 of the plurality of fixing holes 15H are arranged on the center line C1 of the fixing portion 15. It is shifted to the left with respect to the standing piece 19. For this reason, as shown in FIG. 19, the fixture 10 is fixed to the thin structural member 99 such that the butting line J1 between the surfaces 2F of the first and third outer wall plates 2A1 and 2A3 is located near the center of the thin structural member 99. Even so, it is difficult for each specific fixing hole 15T to be disposed near the side surface 99A of the thin structural member 99. As a result, it is possible to prevent problems such as the screw 10B inserted into each specific fixing hole 15T protruding from the side surface 99A of the thin structural member 99 and the side surface 99A of the thin structural member 99 being cracked. In addition, as shown in FIG. 8 and the like, the fixing holes 15H other than the specific fixing holes 15T are also displaced in the width direction with respect to the center line C1, similarly to the specific fixing holes 15T. For this reason, as shown in FIG. 17, the fixture 10 is fixed to the column 9 so that the butting line J1 between the surfaces 2F of the first and third outer wall plates 2A1, 2A3 is located near the center of the column 9. In addition, it is possible to prevent the fixing holes 15H from being arranged near the side surface 9A of the column member 9. For this reason, the screws 10B inserted into the fixing holes 15H protrude from the side surfaces 9A and 99A of the column member 9 and the thin structure member 99, or the side surfaces 9A and 99A of the column member 9 and the thin structure member 99 are broken. Troubles, such as running, can be prevented.

ここで、図２０及び図２１に比較の形態の取付具を示す。比較の形態の取付具では、中央のＵ字状固定部１５Ｂは、中心線Ｃ１上に設けられている。左方のＵ字状固定部１５Ｂは、中心線Ｃ１よりも左方にずれた位置に設けられている。右方のＵ字状固定部１５Ｂは、中心線Ｃ１よりも右方にずれた位置に設けられている。   Here, FIGS. 20 and 21 show a fixture of a comparative form. In the attachment of the comparative example, the central U-shaped fixing portion 15B is provided on the center line C1. The left U-shaped fixing portion 15B is provided at a position shifted leftward from the center line C1. The right U-shaped fixing portion 15B is provided at a position shifted to the right from the center line C1.

中央のＵ字状固定部１５Ｂに貫設された２つの固定孔１５Ｈは、中心線Ｃ１上に配置されている。左方のＵ字状固定部１５Ｂに貫設された２つの固定孔１５Ｈが中心線Ｃ１に対して左方にずれる距離はＬＧ２である。右方のＵ字状固定部１５Ｂに貫設された２つの固定孔１５Ｈが中心線Ｃ１に対して右方にずれる距離はＬＧ３（＝ＬＧ２）である。つまり、本実施の形態では、実施例の形態に係る特定固定孔１５Ｔが無く、各固定孔１５Ｈが中心線Ｃ１に対して対称に配置されている。   Two fixing holes 15H penetrating through the central U-shaped fixing portion 15B are arranged on the center line C1. The distance in which the two fixing holes 15H penetrating the left U-shaped fixing portion 15B are shifted to the left with respect to the center line C1 is LG2. The distance in which the two fixing holes 15H penetrating the right U-shaped fixing portion 15B are shifted rightward with respect to the center line C1 is LG3 (= LG2). That is, in the present embodiment, there is no specific fixing hole 15T according to the embodiment, and the fixing holes 15H are arranged symmetrically with respect to the center line C1.

比較の形態のその他の構成は、実施例の形態と同様である。このため、実施例の形態と同一の構成については同一の符号を付して説明を省略又は簡略する。   Other configurations of the comparative embodiment are the same as those of the embodiment. Therefore, the same components as those of the embodiment are denoted by the same reference numerals, and description thereof will be omitted or simplified.

図２１に示すように、細い構造部材９９に比較の形態の取付具を固定する場合において、第１、３外壁板２Ａ１、２Ａ３の表面２Ｆ同士の突合せラインＪ１が細い構造部材９９の中央付近に位置するように取付具１０を細い構造部材９９に固定すると、中央の２つの固定孔１５Ｈが細い構造部材９９の側面９９Ａの近傍に配置されてしまう。その結果、中央の２つの固定孔１５Ｈに挿通されるネジ１０Ｂが細い構造部材９９の側面９９Ａから突き出したり、細い構造部材９９の側面９９Ａが割れてしまったりする等の不具合が発生し易くなる。   As shown in FIG. 21, when the attachment of the comparative embodiment is fixed to the thin structural member 99, the butting line J1 between the surfaces 2F of the first and third outer wall plates 2A1 and 2A3 is located near the center of the thin structural member 99. If the fixture 10 is fixed to the thin structural member 99 so as to be located, the two center fixing holes 15H are arranged near the side surface 99A of the thin structural member 99. As a result, problems such as the screw 10B inserted into the two center fixing holes 15H protruding from the side surface 99A of the thin structural member 99 and the side surface 99A of the thin structural member 99 being cracked easily occur.

したがって、実施例の形態の取付具１０では、各外壁板２の荷重を幅方向においてバランスよく支持できるとともに、細い構造部材９９に固定される場合でも良好な施工性を発揮することができる。   Therefore, with the fixture 10 of the embodiment, the load of each outer wall plate 2 can be supported in a well-balanced manner in the width direction, and good workability can be exhibited even when it is fixed to the thin structural member 99.

また、この取付具１０では、図１７及び図１９に示すように、第１外壁板２Ａ１の裏側左右接合部２２と、第３外壁板２Ａ３の表側左右接合部２１とは、固定部１５の中心線Ｃ１上に配置された立設片１９に対して左方にずれた位置で重なり合う。換言すると、中心線Ｃ１に対して左方にずれた位置に配置された特定固定孔１５Ｔは、裏側左右接合部２２と表側左右接合部２１とが重なり合う範囲内、又はその重なり合う範囲の近傍に配置される。このため、図１９に示すように、細い構造部材９９に取付具１０を固定する場合において、第１、３外壁板２Ａ１、２Ａ３の表面２Ｆ同士の突合せラインＪ１が細い構造部材９９の中央付近に位置するように取付具１０を細い構造部材９９に固定しても、特定固定孔１５Ｔが細い構造部材９９の側面９９Ａの近傍に配置され難くなる。その結果、この取付具１０では、良好な施工性を一層発揮することができる。   In addition, in this attachment 10, as shown in FIGS. 17 and 19, the rear left / right joint 22 of the first outer wall plate 2A1 and the front left / right joint 21 of the third outer wall plate 2A3 are at the center of the fixing portion 15. It overlaps with the standing piece 19 arranged on the line C1 at a position shifted leftward. In other words, the specific fixing hole 15T arranged at a position shifted to the left with respect to the center line C1 is arranged in a range where the rear left / right joint 22 and the front left / right joint 21 overlap or in the vicinity of the overlapping range. Is done. For this reason, as shown in FIG. 19, when fixing the fixture 10 to the thin structural member 99, the butting line J1 between the surfaces 2F of the first and third outer wall plates 2A1, 2A3 is located near the center of the thin structural member 99. Even if the fixture 10 is fixed to the thin structural member 99 so as to be located, the specific fixing hole 15T is less likely to be disposed near the side surface 99A of the thin structural member 99. As a result, with this attachment 10, good workability can be further exhibited.

さらに、この取付具１０では、図８に示す特定固定孔１５Ｔが中心線Ｃ１に対してずれる距離ＬＧ１は、図１７及び図１９に示す裏側左右接合部２２及び表側左右接合部２１の重なり幅ＷＬ１の１／４以上、かつ重なり幅ＷＬ１の３／４以下に設定されている。これにより、この取付具１０では、特定固定孔１５Ｔが図１７及び図１９に示す範囲Ｅ１内に位置する。その結果、特定固定孔１５Ｔが細い構造部材９９の側面９９Ａの近傍に一層配置され難くなり、良好な施工性をより一層発揮することができる。なお、図２１に示す比較の形態では、中央の２つの固定孔１５Ｈが範囲Ｅ１の外に位置するので、細い構造部材９９の側面９９Ａの近傍に配置され易い。また、図示は省略するが、第１、３外壁板２Ａ１、２Ａ３の裏面２Ｂ同士が突き合わされる立設片１９が細い構造部材９９の中央付近に位置するように取付具１０を細い構造部材９９に固定する場合でも、「ＷＬ１×１／４≦ＬＧ１≦ＷＬ１×３／４」という設定により、各特定固定孔１５Ｔが細い構造部材９９の反対側の側面９９Ａの近傍に配置され難くなる。   Further, in the mounting fixture 10, the distance LG1 at which the specific fixing hole 15T shown in FIG. 8 is displaced from the center line C1 is the overlap width WL1 of the back left and right joints 22 and the front left and right joints 21 shown in FIGS. And ３ or less of the overlap width WL1. Thereby, in this attachment 10, the specific fixing hole 15T is located within the range E1 shown in FIG. 17 and FIG. As a result, it becomes more difficult for the specific fixing hole 15T to be disposed near the side surface 99A of the thin structural member 99, so that good workability can be further exhibited. In the comparative example shown in FIG. 21, the two center fixing holes 15 </ b> H are located outside the range E <b> 1, so that they are easily arranged near the side surface 99 </ b> A of the thin structural member 99. Although not shown, the mounting member 10 is thinned so that the standing piece 19 where the back surfaces 2B of the first and third outer wall plates 2A1 and 2A3 abut each other is located near the center of the thin structural member 99. Even when the fixing member is fixed to the position, the specific fixing holes 15T are less likely to be arranged in the vicinity of the side surface 99A on the opposite side of the thin structural member 99 by the setting of “WL1 × 1/4 ≦ LG1 ≦ WL1 × 3/4”.

また、この取付具１０では、図８及び図１９等に示すように、垂直方向に複数並ぶ特定固定孔１５Ｔに対し複数のネジ１０Ｂで留め付けることにより、取付具１０を細い構造部材９９に一層強固に固定することができる。特に取付具１０の回転を防止できる。   In addition, in this mounting fixture 10, as shown in FIGS. 8 and 19, the mounting fixture 10 is further fastened to the thin structural member 99 by fastening with a plurality of screws 10B to a plurality of specific fixing holes 15T arranged in a vertical direction. Can be fixed firmly. In particular, rotation of the fixture 10 can be prevented.

以上において、本発明の形態を実施の形態に即して説明したが、本発明の形態は上記実施の形態に制限されるものではなく、その趣旨を逸脱しない範囲で適宜変更して適用できることはいうまでもない。   In the above, the embodiments of the present invention have been described with reference to the embodiments.

実施の形態では、支承片１３に突起部１７Ｃ、１７Ｌ、１７Ｒが設けられているが、この構成には限定されない。例えば、支承片１３から突起部１７Ｃ、１７Ｌ、１７Ｒを無くして、第２、４外壁板２Ａ２、２Ａ４の端面が支承片１３の上面に直に当接するようにしてもよい。   In the embodiment, the projections 17C, 17L, and 17R are provided on the support piece 13, but the present invention is not limited to this configuration. For example, the end portions of the second and fourth outer wall plates 2A2 and 2A4 may be brought into direct contact with the upper surface of the support piece 13 by eliminating the protrusions 17C, 17L and 17R from the support piece 13.
