Description

本発明は、建物の外壁などの壁を断熱パネルで形成する際に用いられる断熱パネルの接続構造に関するものであり、特に、高層ビルや足場を組めない場所など、屋外側から外壁の施工が行ないにくい施工現場で好適に用いるものである。 The present invention relates to a connection structure of a heat insulating panel used when a wall such as an outer wall of a building is formed with a heat insulating panel, and in particular, an outer wall is constructed from the outdoor side such as a place where a high-rise building or a scaffold cannot be assembled. It is suitable for use in difficult construction sites.

従来より、二枚の金属外皮の間に断熱材を充填して断熱パネルを形成し、複数枚の断熱パネルを縦横に並設することにより外壁を形成することが行なわれている（例えば、特許文献１参照）。このような断熱パネルの両方の側端部には断面略Ｌ字状の目地片が突設されており、複数枚の断熱パネルを横方向に並設すると、隣り合う断熱パネルの目地片の間が縦方向の目地として形成されるものである。また、この目地には隣り合う断熱パネルの接続部分（目地部分）における防水性を確保するために、コーキング剤が目地の全長に亘って充填されている。
特開２０００−９６８０６号公報 Conventionally, a heat insulating panel is formed by filling a heat insulating material between two metal skins, and an outer wall is formed by arranging a plurality of heat insulating panels side by side (for example, patents). Reference 1). Joint pieces having a substantially L-shaped cross section project from both side end portions of such a heat insulation panel, and when a plurality of heat insulation panels are juxtaposed in a horizontal direction, the joint pieces between adjacent heat insulation panels are arranged. Are formed as vertical joints. Moreover, in order to ensure the waterproofness in the connection part (joint part) of an adjacent heat insulation panel, this joint is filled with the caulking agent over the full length of a joint.
JP 2000-96806 A

しかし、上記のようにコーキング剤により隣り合う断熱パネルの接続部分における防水性を確保する場合、コーキング剤を目地に完全に隙間なく充填しなければならず、このために、コーキング剤は建物の屋外側となる場所から目地に充填する作業が必要となる。従って、高層ビルではゴンドラを使用して、また低層ビルであっても足場を組んで作業しなければならず、いずれの場合でも高所における作業であって危険を伴うものであり、また、隣り合う建物の間に狭小スペースしか確保できない場合では、作業が行ないにくいという問題があった。しかも、コーキング剤を目地に完全に隙間なく充填することは難しく、さらには、経年劣化によりコーキング剤に亀裂や破損が生じることもあるために、隣り合う断熱パネルの接続部分の防水性が損なわれるという問題があった。 However, in order to secure the waterproofness at the connecting portion of the adjacent heat insulating panels with the caulking agent as described above, the caulking agent must be completely filled in the joint without any gap. It is necessary to fill the joint from the outside location. Therefore, a high-rise building must use a gondola and even a low-rise building must be constructed with a scaffold. In any case, it is a work in a high place and is dangerous. When only a small space can be secured between matching buildings, there is a problem that it is difficult to work. Moreover, it is difficult to completely fill the joint with the caulking agent without any gaps. Furthermore, since the caulking agent may be cracked or damaged due to aging, the waterproofness of the connection part of adjacent heat insulation panels is impaired. There was a problem.

本発明は上記の点に鑑みてなされたものであり、断熱パネルの接続部分の防水性を確保するためにゴンドラや足場での作業をなくして安全で容易に断熱パネルを施工することができる断熱パネルの接続構造を提供することを目的とするものである。 The present invention has been made in view of the above points, and it is possible to safely and easily construct a heat insulation panel without the work on a gondola or a scaffold in order to ensure the waterproofness of the connection portion of the heat insulation panel. The object is to provide a panel connection structure.

本発明の断熱パネルの接続構造は、二枚の金属外皮１、２の間に断熱材３を充填して形成される断熱パネルＡの接続構造において、断熱パネルＡの側端部に目地片４を側方に突出させ、隣接する断熱パネルＡ、Ａをその目地片４を対向させて配設すると共に対向する目地片４、４により目地５を形成し、目地５内に防水部材６を設けると共に目地５に防水部材６よりも屋外側空間に連通する開口部１０を設け、目地５より屋内側に樋部材７を配設すると共に目地片４と樋部材７との間に気密部材８を設け、防水部材６と樋部材７の間を屋外側空間の気圧と等しい等圧空間９として形成して成ることを特徴とするものである。 The connection structure of the heat insulation panel of the present invention is the connection structure of the heat insulation panel A formed by filling the heat insulating material 3 between the two metal shells 1 and 2, and the joint piece 4 at the side end of the heat insulation panel A. Projecting sideways, adjacent heat insulating panels A and A are disposed with the joint pieces 4 facing each other, and joints 5 are formed by the facing joint pieces 4 and 4, and a waterproof member 6 is provided in the joint 5. At the same time, an opening 10 is provided in the joint 5 so as to communicate with the outdoor side space from the waterproof member 6, and the collar member 7 is disposed indoors from the joint 5, and the airtight member 8 is provided between the joint piece 4 and the collar member 7. It is characterized in that the space between the waterproof member 6 and the eaves member 7 is formed as an isobaric space 9 equal to the atmospheric pressure in the outdoor side space.

本発明にあっては、気密部材８にスリット１２を形成し、目地片４をスリット１２に差し込むことにより断熱パネルＡの目地片４に気密部材８を取り付けることができる。 In the present invention, the airtight member 8 can be attached to the joint piece 4 of the heat insulation panel A by forming the slit 12 in the airtight member 8 and inserting the joint piece 4 into the slit 12.

また、本発明にあっては、防水部材６に被差し込み凹部１３を形成し、目地片４を被差し込み凹部１３を差し込むことにより断熱パネルＡの目地片４に防水部材６を取り付けることができる。 Moreover, in this invention, the waterproof member 6 can be attached to the joint piece 4 of the heat insulation panel A by forming the insertion recessed part 13 in the waterproof member 6, and inserting the joint piece 4 in the inserted recessed part 13. FIG.

本発明にあっては、防水部材６と樋部材７の間を防水部材６よりも屋外側空間の気圧と等しい等圧空間９として形成するので、防水部材６の屋外側空間と屋内側空間との間で気圧差が生じないようにすることができ、当該気圧差に起因して雨水が目地５内を屋内側に進入するのを防止することができるものである。従って、防水部材６と目地片４との間に多少隙間があったり、経年劣化により防水部材６に亀裂や破損が生じることがあっても、等圧空間９により上記気圧差が生じないために断熱パネルＡ、Ａの接続部分の防水性を低下しにくくすることができるものであり、この結果、従来のようにコーキング剤を屋外側から目地に隙間なく完全に充填する作業が必要が無くなって、断熱パネルの接続部分の防水性を確保するためにゴンドラや足場での作業をなくして屋内側から安全で容易に断熱パネルを施工することができるものである。 In the present invention, since the space between the waterproof member 6 and the eaves member 7 is formed as an equal pressure space 9 that is equal to the atmospheric pressure of the outdoor side space rather than the waterproof member 6, the outdoor side space and the indoor side space of the waterproof member 6 It is possible to prevent the atmospheric pressure difference between the two, and it is possible to prevent rainwater from entering the joint 5 into the indoor side due to the atmospheric pressure difference. Therefore, even if there is a slight gap between the waterproof member 6 and the joint piece 4 or the waterproof member 6 is cracked or broken due to deterioration over time, the pressure difference is not generated by the isostatic space 9. As a result, it is not necessary to completely fill the caulking agent from the outdoor side to the joint without any gaps as in the prior art. In order to ensure the waterproofness of the connecting portion of the heat insulation panel, it is possible to construct the heat insulation panel safely and easily from the indoor side without the work on the gondola and the scaffolding.

また、気密部材８に形成したスリット１２に目地片４を差し込んで断熱パネルＡの目地片４に気密部材８を取り付けることにより、気密部材８を断熱パネルＡの目地片４に位置決めして保持した状態で断熱パネルＡを施工することができ、断熱パネルＡの施工をより容易に行うことができるものである。 Moreover, the airtight member 8 is positioned and held on the joint piece 4 of the heat insulation panel A by inserting the joint piece 4 into the slit 12 formed in the airtight member 8 and attaching the airtight member 8 to the joint piece 4 of the heat insulation panel A. The heat insulation panel A can be constructed in a state, and the insulation panel A can be constructed more easily.

また、防水部材６に形成した被差し込み凹部１３に目地片４を差し込んで断熱パネルＡの目地片４に防水部材６を取り付けることにより、防水部材６を断熱パネルＡの目地片４に位置決めして保持した状態で断熱パネルＡを施工することができ、断熱パネルＡの施工をより容易に行うことができるものである。 Further, the waterproof member 6 is positioned on the joint piece 4 of the heat insulation panel A by inserting the joint piece 4 into the insertion recess 13 formed in the waterproof member 6 and attaching the waterproof member 6 to the joint piece 4 of the heat insulation panel A. The heat insulation panel A can be constructed while being held, and the insulation panel A can be constructed more easily.

Moreover, the edge parts of the flange members 7 and 7 adjacent up and down are connected without a gap. Thus, as shown in FIG. 17, the heat insulation panels A and A can be connected and attached adjacent to each other in the vertical direction.

上記のようにして複数枚の断熱パネルＡ、Ａ…を横方向及び縦方向に並べて接続していくことにより、建物の壁（外壁）を形成することができるが、この壁には縦方向に長い目地５と横目地７１とが交差するように形成され、また、図１８に示すように、この交差部分において上側の断熱パネルＡに取り付けた防水部材６の第一防水片４２の下端と、下側の断熱パネルＡに取り付けた防水部材６の第一防水片４２の上端との間に隙間ができて開口部（通気孔）１０が形成されることになる。すなわち、開口部１０は縦方向においては第一凹段部３５と第二凹段部３６の間に形成され、横方向においては支持片３４の屋外側に形成されるものである。また、防水部材６の第一防水片４２よりも屋内側の目地５内の空間及び樋部材７の連結片７ａよりも屋外側の空間は、気密部材８により樋部材７よりも屋内側の空間に対して密閉されて通気性がないように形成されている。従って、開口部１０とそれよりも上側の上部気密部材４６との間において、防水部材６の第一防水片４２よりも屋内側の目地５内の空間及び樋部材７の連結片７ａよりも屋外側の空間は、上記開口部１０により防水部材６の第一防水片４２よりも屋外側の空間に開放され、図１９に示すように、開口部１０を通じて目地５内に外気が導入されるものであり、これにより、第一防水片４２よりも屋外側の空間の気圧と等しい等圧空間９として形成することができる。そして、等圧空間９により、防水部材６の第一防水片４２の屋外側の空間と屋内側の空間との間で気圧差が生じないようにすることができ、気圧差に起因して雨水が目地５内を屋内側に進入するのを防止することができるものである。また、上記のように断熱パネルＡを構造材６６に屋内側から取り付けることができ、足場での作業をなくして安全で容易に断熱パネルを施工することができるものである。 A wall (outer wall) of a building can be formed by arranging and connecting a plurality of heat insulating panels A, A... In the horizontal direction and the vertical direction as described above. The long joint 5 and the horizontal joint 71 are formed so as to intersect with each other, and as shown in FIG. 18, the lower end of the first waterproof piece 42 of the waterproof member 6 attached to the upper heat insulation panel A at the intersection, A gap is formed between the upper end of the first waterproof piece 42 of the waterproof member 6 attached to the lower heat insulation panel A, and an opening (vent hole) 10 is formed. That is, the opening 10 is formed between the first concave step 35 and the second concave step 36 in the vertical direction, and is formed on the outdoor side of the support piece 34 in the horizontal direction. Further, the space inside the joint 5 on the indoor side with respect to the first waterproof piece 42 of the waterproof member 6 and the space on the outdoor side with respect to the connecting piece 7a of the flange member 7 are space closer to the indoor side than the flange member 7 due to the airtight member 8. Is formed so as not to be air permeable. Therefore, between the opening 10 and the upper airtight member 46 above it, the space in the joint 5 on the indoor side with respect to the first waterproof piece 42 of the waterproof member 6 and the connecting piece 7a of the eaves member 7 are closer. The outer space is opened to the outdoor side space from the first waterproof piece 42 of the waterproof member 6 by the opening 10, and the outside air is introduced into the joint 5 through the opening 10 as shown in FIG. 19. Thus, it is possible to form the isobaric space 9 equal to the atmospheric pressure of the outdoor side space with respect to the first waterproof piece 42. And the isobaric space 9 can prevent a pressure difference between the outdoor side space and the indoor side space of the first waterproof piece 42 of the waterproof member 6, and rainwater is caused by the pressure difference. Can prevent the inside of the joint 5 from entering the indoor side. Further, as described above, the heat insulation panel A can be attached to the structural member 66 from the indoor side, and the work on the scaffold can be eliminated and the heat insulation panel can be constructed safely and easily.

雨水が目地５を屋内側に向かって移動させるエネルギーとしては、重力、表面張力、毛細管現象、運動エネルギー、気流及び気圧差の６つがある。 There are six types of energy that cause rainwater to move the joint 5 toward the indoor side: gravity, surface tension, capillary action, kinetic energy, airflow, and atmospheric pressure difference.

目地５に屋内側に向かって下り傾斜する経路があると、重力のエネルギーにより雨水が屋内側に進入しやすくなるが、本発明では上部気密部材４６の外側気密部５２の上面を屋外側に向かって傾斜する傾斜面７９として形成しているので、開口部１０から目地５内に進入した雨水が自重により屋内側に向かって移動するのを防止することができる。 When the joint 5 has a path inclined downward toward the indoor side, it becomes easy for rainwater to enter the indoor side due to the energy of gravity. However, in the present invention, the upper surface of the outer airtight portion 52 of the upper airtight member 46 faces the outdoor side. Therefore, it is possible to prevent rainwater that has entered the joint 5 from the opening 10 from moving toward the indoor side due to its own weight.

また、雨水が断熱パネルＡの金属外皮１に付着すると、雨水の表面張力により雨水が金属外皮１の表面を伝わって目地５に進入しやすくなるが、本発明では目地５内に防水部材６を設けると共に上部気密部材４６の外側気密部５２の上面を屋外側に向かって傾斜する傾斜面７９として形成しているので、雨水が目地５内に進入しにくく、また、進入したとしても雨水が表面張力により屋内側に向かって移動するのを防止することができる。 In addition, when rainwater adheres to the metal shell 1 of the heat insulation panel A, rainwater easily enters the joint 5 through the surface of the metal shell 1 due to the surface tension of the rainwater. In the present invention, the waterproof member 6 is provided in the joint 5. In addition, since the upper surface of the outer airtight portion 52 of the upper airtight member 46 is formed as an inclined surface 79 inclined toward the outdoor side, it is difficult for rainwater to enter the joint 5, and even if it enters, the rainwater is on the surface. It can prevent moving toward the indoor side by tension.

また、目地５の幅寸法が狭いと毛細管現象が起こり、重力に逆らって目地５に雨水が進入する恐れがあるが、本発明では毛細管現象が生じない程度の幅寸法（例えば、２０ｍｍ）に目地５を形成しているので、雨水が目地５内に進入しにくく、また、進入したとしても雨水が表面張力により屋内側に向かって移動するのを防止することができる。 In addition, if the width dimension of the joint 5 is narrow, a capillary phenomenon occurs, and rainwater may enter the joint 5 against the gravity. However, in the present invention, the joint dimension is set to a width dimension that does not cause the capillary phenomenon (for example, 20 mm). 5 is formed, it is difficult for rainwater to enter the joint 5 and even if it enters, rainwater can be prevented from moving indoors due to surface tension.

また、風速等によって雨水が断熱パネルＡの方に向かう運動エネルギーを持つと、雨水が目地５に進入する恐れがあるが、本発明では防水部材６の第一防水片４２と第二防水片４５により目地５に雨水が進入するのを防止することができる。 Further, if rainwater has kinetic energy directed toward the heat insulation panel A due to wind speed or the like, rainwater may enter the joint 5, but in the present invention, the first waterproof piece 42 and the second waterproof piece 45 of the waterproof member 6. Thus, rainwater can be prevented from entering the joint 5.

また、目地５が建物の屋内に通じていると、風を伴った降雨時に目地５を通る気流が生じ、ある流速以上の気流では雨水が横飛びして建物の屋内側に進入する恐れがあるが、本発明では気密部材８により目地５と建物の屋内側空間とが通じないように閉塞していると共に防水部材６の第一防水片４２と第二防水片４５を設けているので、目地５に雨水が進入するのを防止することができる。 In addition, if the joint 5 communicates with the interior of the building, an airflow passing through the joint 5 is generated during a rain accompanied by wind, and rainwater may jump to the inside of the building when the airflow exceeds a certain flow velocity. However, in the present invention, the airtight member 8 closes the joint 5 and the indoor space of the building so as not to communicate with each other, and the first waterproof piece 42 and the second waterproof piece 45 of the waterproof member 6 are provided. 5 can prevent rainwater from entering.

また、目地５内に雨水が進入した場合、建物の屋内側の空間と屋外側の空間に気圧差が生じると、圧力により雨水が屋内側に移動するが、本発明では開口部１０を設け、ここから目地５内及び樋部材７の屋外側空間に外気を自然に導入して等圧空間９を形成しているので、目地５から屋内側に雨水が進入するのを防止することができる。 In addition, when rainwater enters the joint 5, if a pressure difference occurs between the indoor space and the outdoor space of the building, the rainwater moves indoors due to pressure, but in the present invention, the opening 10 is provided, Since the isobaric space 9 is formed by naturally introducing outside air into the joint 5 and the outdoor space of the eaves member 7 from here, it is possible to prevent rainwater from entering the indoor side from the joint 5.

そして、本発明では、樋部材７にまで雨水が到達しても、その雨水を上部気密部材４６の傾斜面５５、７９に沿って屋外側へと流すことができ、目地５及び開口部１０を通じて壁の屋外に排水することができるものである。 In the present invention, even if rainwater reaches the heel member 7, the rainwater can flow to the outdoor side along the inclined surfaces 55 and 79 of the upper airtight member 46, through the joint 5 and the opening 10. It can be drained outside the wall.

尚、本発明においては、等圧空間９と防水部材６よりも屋外側の空間とが５０Ｐａ（５ｋｇｆ／ｍ^２）以下の圧力差であれば等圧とみなすことができ、これ以上の圧力差が生じないように、建物の高さ、最大風圧、目地５の幅寸法、嵌合凹部３８と嵌合凸部４１との嵌合深さなどに応じて、開口部１０の開口面積を設定することができる。 In the present invention, if the pressure difference between the isobaric space 9 and the space outside the waterproofing member 6 is 50 Pa (5 kgf / m ² ) or less, it can be regarded as isobaric pressure, and the pressure difference larger than this. The opening area of the opening 10 is set according to the height of the building, the maximum wind pressure, the width dimension of the joint 5, the fitting depth between the fitting recess 38 and the fitting protrusion 41, and the like. be able to.

上記のように複数枚の断熱パネルＡ、Ａ…を用いて壁を形成する場合、一部の断熱パネルＡをサッシＢに置き換えて窓などを形成することがあるが、このような場合でも本発明の断熱パネルＡの接続構造を用いることができる。サッシＢは枠部７３とその内側にはめられた窓部材（図示省略）から構成されており、枠部７３の上端には上面が開口するサッシ嵌合凹部７４が横方向の全長に亘って形成されている。また、枠部７３の下面には嵌合突起７５が横方向の全長に亘って形成されていると共に嵌合突起７５よりも屋外側には嵌合突起７５より下方に突出するサッシ被覆部８６が枠部７３の下面の横方向の全長に亘って形成されている。さらに、枠部７３の両方の側面には断熱パネルＡの目地片４と同様の目地片４が縦方向の全長に亘って突設されている。 As described above, when a wall is formed by using a plurality of heat insulation panels A, A..., Some heat insulation panels A may be replaced with sashes B to form windows and the like. The connection structure of the heat insulation panel A of the invention can be used. The sash B is composed of a frame portion 73 and a window member (not shown) fitted inside the frame portion 73, and a sash fitting recess 74 whose upper surface is opened is formed at the upper end of the frame portion 73 over the entire length in the lateral direction. Has been. Further, a fitting projection 75 is formed on the lower surface of the frame portion 73 over the entire length in the lateral direction, and a sash covering portion 86 projecting downward from the fitting projection 75 on the outdoor side of the fitting projection 75. It is formed over the entire lateral length of the lower surface of the frame portion 73. Further, joint pieces 4 similar to the joint pieces 4 of the heat insulation panel A are provided on both side surfaces of the frame portion 73 so as to protrude over the entire length in the vertical direction.

そして、このサッシＢには上記と同様の防水部材６、樋部材７、気密部材８を取り付けた状態で、上記断熱パネルＡと同様にして屋内側から施工されるものである。ここで、図２０に示すように、サッシＢは枠部７３の上部に装着したボルト等の固定具６５及びこれに螺合されるナット等の螺合具７０により胴縁等の構造材６６に取り付けられる。また、サッシＢとその上側の断熱パネルＡとは、サッシＢのサッシ嵌合凹部７４に断熱パネルＡの嵌合凸部４１を嵌合することにより接続されると共に、サッシＢとその下側の断熱パネルＡとは、サッシＢの嵌合突起７５を断熱パネルＡの嵌合凹部３８に嵌合することにより接続される。この時、サッシ嵌合凹部７４の底面と嵌合凸部４１の下面との間及び嵌合突起７５の下端と嵌合凹部３８の底面との間にはパッキン７６が設けられている。さらに、図２１に示すように、横方向に隣接させた断熱パネルＡとサッシＢでは、断熱パネルＡ、Ａを横方向に隣接させた場合と同様に目地５が形成されると共に防水部材６、６が目地５内に配置される。また、目地５内は開口部１０により開放されると共に、横方向に隣接させた断熱パネルＡとサッシＢに設けた上部気密部材４６、４６の外側気密部５２、５２同士が樋部材７内で横方向に隣接して密着するものであり、これにより、開口部１０とそれよりも上側の上部気密部材４６との間において、防水部材６の第一防水片４２よりも屋内側の目地５内の空間及び樋部材７の連結片７ａよりも屋外側の空間は、上記開口部１０により防水部材６の第一防水片４２よりも屋外側の空間に開放され、開口部１０を通じて目地５内に外気が導入されるものであり、これにより、第一防水片４２よりも屋外側の空間の気圧と等しい等圧空間９として形成することができる。この結果、防水部材６の第一防水片４２の屋外側の空間と屋内側の空間との間で気圧差が生じないようにすることができ、気圧差に起因して雨水が目地５内を屋内側に進入するのを防止することができるものである。 The sash B is constructed from the indoor side in the same manner as the heat insulation panel A, with the waterproof member 6, the eaves member 7 and the airtight member 8 similar to the above attached. Here, as shown in FIG. 20, the sash B is attached to the structural member 66 such as the trunk edge by a fixing tool 65 such as a bolt attached to the upper portion of the frame portion 73 and a screwing tool 70 such as a nut screwed to the fixing tool 65. It is attached. Further, the sash B and the heat insulating panel A on the upper side thereof are connected by fitting the fitting convex portion 41 of the heat insulating panel A to the sash fitting concave portion 74 of the sash B, and the sash B and the lower side thereof. The heat insulation panel A is connected by fitting the fitting projection 75 of the sash B into the fitting recess 38 of the heat insulation panel A. At this time, packings 76 are provided between the bottom surface of the sash fitting recess 74 and the bottom surface of the fitting projection 41 and between the lower end of the fitting protrusion 75 and the bottom surface of the fitting recess 38. Furthermore, as shown in FIG. 21, in the heat insulation panel A and the sash B adjacent to each other in the lateral direction, the joint 5 is formed and the waterproof member 6 is formed as in the case where the heat insulation panels A and A are adjacent to each other in the horizontal direction. 6 is arranged in the joint 5. Further, the inside of the joint 5 is opened by the opening 10, and the outer airtight portions 52, 52 of the upper airtight members 46, 46 provided in the heat insulating panel A and the sash B adjacent to each other in the lateral direction are in the brim member 7. Adjacent to each other in the lateral direction, and thereby, between the opening 10 and the upper airtight member 46 above the opening 10, the inside of the joint 5 on the indoor side with respect to the first waterproof piece 42 of the waterproof member 6. And the space on the outdoor side of the connecting piece 7 a of the flange member 7 are opened to the space on the outdoor side of the first waterproof piece 42 of the waterproof member 6 by the opening 10, and enter the joint 5 through the opening 10. Outside air is introduced, and as a result, it is possible to form the isobaric space 9 equal to the atmospheric pressure of the space on the outdoor side of the first waterproof piece 42. As a result, it is possible to prevent a difference in atmospheric pressure between the outdoor side space and the indoor side space of the first waterproof piece 42 of the waterproof member 6, and rainwater can enter the joint 5 due to the atmospheric pressure difference. It is possible to prevent entry into the indoor side.

尚、上記では、断熱パネルＡが厚くて（５０ｍｍ程度）、樋部材７と構造材６６との間隔が広くなるためにハット状のバックアップ材６０を用いて断熱パネルＡと樋部材７とを連結しているが、断熱パネルＡが薄い場合（３５ｍｍ程度）などでは、樋部材７と構造材６６との間にほとんど隙間が開かない。そこで、この場合は、図２２に示すように、断熱パネルＡと樋部材７とを板状の固定板７７で連結することができる。 In the above, since the heat insulation panel A is thick (about 50 mm) and the gap between the flange member 7 and the structural material 66 is wide, the hat-like backup material 60 is used to connect the heat insulation panel A and the flange member 7. However, when the heat insulation panel A is thin (about 35 mm), a gap is hardly opened between the eaves member 7 and the structural material 66. Therefore, in this case, as shown in FIG. 22, the heat insulating panel A and the eaves member 7 can be connected by a plate-shaped fixing plate 77.
