Description

本発明は、外断熱工法により断熱壁を形成する際などに適用される断熱パネルの施工構造に関するものである。   The present invention relates to a construction structure of a heat insulating panel applied when a heat insulating wall is formed by an outer heat insulating method.

従来より、既設の鉄筋コンクリート製の下地壁(RC壁)に断熱材と外装材とを取り付けて外断熱壁を形成することが行われている(例えば、特許文献1参照)。この場合、壁材留具を用いて、下地壁の屋外側にボード状の断熱材を取り付けた後、この断熱材の屋外側に板状の外装材を取り付けるようにしている。   Conventionally, an outer heat insulating wall is formed by attaching a heat insulating material and an exterior material to an existing reinforced concrete base wall (RC wall) (see, for example, Patent Document 1). In this case, a board-shaped heat insulating material is attached to the outdoor side of the base wall using a wall material fastener, and then a plate-shaped exterior material is attached to the outdoor side of the heat insulating material.

断熱材20は樹脂発泡板で形成されている。この樹脂発泡板としてはビーズ法発泡スチロール(EPS)などを例示することができる。断熱材20は縦方向(上下方向)に長く横方向に短い矩形板状に形成されている。断熱材20の上端部は縦接続部21として形成されている。縦接続部21は断熱材20の短辺に沿って横方向の略全長にわたって形成されている。断熱材20の一方の側端部は横接続部22として形成されている。横接続部22は断熱材20の長辺に沿って縦方向の略全長にわたって形成されている。縦接続部21及び横接続部22以外の部分において、断熱材20の表面には突条部23及び通気溝24が設けられている。突条部23は断熱材20の上下方向(縦方向)と略平行に長く形成されている。突条部23は複数本設けられている。複数本の突条部23は断熱材20の横方向に所定の間隔を介して並んで設けられている。隣り合う突条部23の間の空間は通気溝24として形成されている。従って、複数本の通気溝24も断熱材20の上下方向(縦方向)と略平行に長く形成されている。突条部23は縦接続部21の表面と横接続部22の表面と通気溝24の底面よりも突出して形成されている。尚、複数本の通気溝24のうち、横接続部22に隣接する通気溝24aはその底面と横接続部22の表面とが連続して面一に形成されている。従って、横接続部22と通気溝24aの間には突条部23は設けられていない。   The heat insulating material 20 is formed of a resin foam plate. Examples of the resin foam plate include beaded polystyrene foam (EPS). The heat insulating material 20 is formed in a rectangular plate shape that is long in the vertical direction (vertical direction) and short in the horizontal direction. An upper end portion of the heat insulating material 20 is formed as a vertical connection portion 21. The vertical connection portion 21 is formed over substantially the entire length in the lateral direction along the short side of the heat insulating material 20. One side end portion of the heat insulating material 20 is formed as a lateral connection portion 22.

Of the plurality of ventilation grooves 24, the ventilation groove 24 a adjacent to the lateral connection portion 22 is formed such that the bottom surface thereof and the surface of the lateral connection portion 22 are continuously flush with each other. Accordingly, the protrusion 23 is not provided between the lateral connection portion 22 and the ventilation groove 24a.

外装材30は窯業系材料で形成されている。窯業系材料は、例えば、セメントや骨材やパルプ繊維などを含有する水硬性材料を所定の形状に成形した後、養生硬化することにより得ることができる。外装材30は縦方向(上下方向)に長く横方向に短い矩形板状に形成されている。外装材30の縦方向の長さと断熱材20の縦方向の長さとは略同じである。また外装材30の横方向の長さと断熱材20の横方向の長さとは略同じである。外装材30の一方の側端部には実部35として受け実部31が設けられている。受け実部31は外装材30の長辺の側端部の略全長にわたって設けられている。受け実部31は外装材30の厚み方向の半分よりも裏面側に偏って設けられている。外装材30の他方の側端部には実部35として突状実部32が設けられている。突状実部32は外装材30の長辺の側端部の略全長にわたって設けられている。突状実部32は外装材30の厚み方向の半分よりも表面側に偏って設けられている。外装材30の突状実部32側の側端部には係止溝33が設けられている。係止溝33は外装材30の長辺の側端部の略全長にわたって設けられている。係止溝33は突状実部32よりも裏面側に設けられている。   The exterior material 30 is formed of a ceramic material. The ceramic material can be obtained by, for example, forming a hydraulic material containing cement, aggregate, pulp fiber, or the like into a predetermined shape and curing it. The packaging material 30 is formed in a rectangular plate shape that is long in the vertical direction (vertical direction) and short in the horizontal direction. The length of the exterior material 30 in the vertical direction and the length of the heat insulating material 20 in the vertical direction are substantially the same. Further, the lateral length of the exterior material 30 and the lateral length of the heat insulating material 20 are substantially the same. A receiving real part 31 is provided as a real part 35 at one end of the exterior material 30. The receiving portion 31 is provided over substantially the entire length of the side edge of the long side of the exterior material 30. The receiving part 31 is provided so as to be biased toward the back side rather than half of the exterior material 30 in the thickness direction.

断熱パネル10は断熱材20の表面側に外装材30を設けることにより形成される。外装材30の裏面は断熱材20の突条部23の表面に接着される。これにより、外装材30と断熱材20とが一体化されて断熱パネル10が形成される。外装材30と断熱材20は互いに縦方向及び横方向にずれて一体化されている。このような断熱パネル10において、外装材30の上端面と突条部23の上端面とが略同じ高さに位置している。従って、断熱材20の縦接続部21は外装材30の上端面よりも上方に突出している。断熱パネル10の下端部において、外装材30の下端部は断熱材20の下端面よりも下方に突出している。外装材30の下端部の裏面側の空間は縦接続凹部11として形成されている。また、外装材30の突状実部32側の側端部は断熱材20の一方の側端面(横接続部22と反対側の側端面)よりも外側に突出している。外装材30の突状実部32側の側端部の裏面側の空間は横接続凹部12として形成されている。外装材30の受け実部31の先端面は、通気溝24aと横接続部22との境界部分に位置している。従って、横接続部22は外装材30の受け実部31の先端面よりも外側(側方)に突出している。外装材30の受け実部31側の側端部は通気溝24aの表面側に位置している。   The heat insulating panel 10 is formed by providing an exterior material 30 on the surface side of the heat insulating material 20. The back surface of the exterior material 30 is bonded to the surface of the protrusion 23 of the heat insulating material 20. Thereby, the exterior material 30 and the heat insulating material 20 are integrated, and the heat insulation panel 10 is formed. The exterior material 30 and the heat insulating material 20 are integrated with each other shifted in the vertical direction and the horizontal direction. In such a heat insulating panel 10, the upper end surface of the exterior material 30 and the upper end surface of the ridge portion 23 are located at substantially the same height. Therefore, the vertical connection portion 21 of the heat insulating material 20 protrudes above the upper end surface of the exterior material 30. In the lower end portion of the heat insulating panel 10, the lower end portion of the exterior material 30 protrudes downward from the lower end surface of the heat insulating material 20. A space on the back surface side of the lower end portion of the exterior material 30 is formed as a longitudinal connection recess 11. Further, the side end portion of the exterior material 30 on the projecting real portion 32 side protrudes outward from one side end surface (the side end surface opposite to the lateral connection portion 22) of the heat insulating material 20. A space on the back surface side of the side end portion of the exterior material 30 on the projecting real portion 32 side is formed as a lateral connection recess 12. The front end surface of the receiving portion 31 of the exterior material 30 is located at a boundary portion between the ventilation groove 24 a and the lateral connection portion 22. Accordingly, the lateral connection portion 22 projects outward (sideward) from the front end surface of the receiving portion 31 of the exterior material 30. A side end portion of the exterior material 30 on the side of the receiving portion 31 is located on the surface side of the ventilation groove 24a.

上記の断熱パネル10は、既存の鉄筋コンクリート製の下地壁(RC壁)60に縦張りにより施工される。図6に断熱パネル10の側端部における取付構造を示す。断熱パネル10は既存の下地壁60の表面(屋外面)に配設される。この場合、断熱パネル10の裏面の断熱材20と下地壁60の表面とを接着剤で接着しても良い。断熱パネル10の横接続部22側の側端部は取付具40で固定される。取付具40は横接続部22の表面側に設けられる。このとき、取付具40と横接続部22の表面との間にはプレート63が設けられる。プレート63は台座として配置されるものである。プレート63は金属板等で平板に形成される。プレート63は取付具40の裏面の面積よりも大きな面積を有する。従って、取付具40を横接続部22の表面に直接配置する場合に比べて、横接続部22にかかる応力を分散することができ、横接続部22が破損しにくくなる。プレート63は横接続部22の表面から通気溝24aの底面に至るまで配置されている。このプレート63の表面に取付具40が配置される。この取付具40は通気溝24aから横接続部22の表面側に至るように配置される。取付具40の固定部41は通気溝24aの側方に位置している。取付具40の当接部46は通気溝24a内において外装材30の受け実部31側の側端部の裏面に当接される。取付具40第一係止片44は受け実部31の表面に係止される。取付具40はビス等の固定具13で下地壁60に固定される。固定具13は固定部41の固定孔42からプレート63及び横接続部22を厚み方向で貫通して下地壁60にまで打ち込まれる。断熱パネル10は複数個の取付具40で取り付けられる。複数個の取付具40は断熱パネル10の側端部に沿って縦方向に所定の間隔を介して設けられる。   The above-described heat insulation panel 10 is constructed by vertical stretching on an existing reinforced concrete foundation wall (RC wall) 60. FIG. 6 shows a mounting structure at the side end of the heat insulating panel 10. The heat insulation panel 10 is disposed on the surface (outdoor surface) of the existing base wall 60. In this case, you may adhere | attach the heat insulating material 20 of the back surface of the heat insulation panel 10, and the surface of the base wall 60 with an adhesive agent. A side end portion of the heat insulating panel 10 on the side of the lateral connection portion 22 is fixed by a fixture 40. The fixture 40 is provided on the surface side of the lateral connection portion 22. At this time, the plate 63 is provided between the fixture 40 and the surface of the lateral connection portion 22. The plate 63 is arranged as a pedestal. The plate 63 is formed of a metal plate or the like into a flat plate. The plate 63 has an area larger than the area of the back surface of the fixture 40. Therefore, compared with the case where the fixture 40 is arrange | positioned directly on the surface of the horizontal connection part 22, the stress concerning the horizontal connection part 22 can be disperse | distributed and the horizontal connection part 22 becomes difficult to be damaged. The plate 63 is disposed from the surface of the lateral connection portion 22 to the bottom surface of the ventilation groove 24a. The fixture 40 is disposed on the surface of the plate 63. The fixture 40 is disposed so as to extend from the ventilation groove 24 a to the surface side of the lateral connection portion 22. The fixing portion 41 of the fixture 40 is located on the side of the ventilation groove 24a. The contact portion 46 of the fixture 40 is in contact with the back surface of the side end portion of the exterior member 30 on the side of the receiving portion 31 in the ventilation groove 24a. The fixture 40 first locking piece 44 is locked to the surface of the receiving portion 31. The fixture 40 is fixed to the base wall 60 with a fixture 13 such as a screw. The fixing tool 13 is driven from the fixing hole 42 of the fixing portion 41 through the plate 63 and the lateral connection portion 22 in the thickness direction to the base wall 60. The heat insulating panel 10 is attached with a plurality of fixtures 40. The plurality of fixtures 40 are provided in the vertical direction along the side end portions of the heat insulating panel 10 with a predetermined interval.

下地壁60には複数枚の断熱パネル10が横方向に並べて取り付けられる。図7に示すように、横方向で隣接する断熱パネル10は横接続部22と横接続凹部12とが接続される。すなわち、横方向で隣接する断熱パネル10のうち、一方の断熱パネル10の横接続部22が他方の断熱パネル10の横接続凹部12に嵌合される。また一方の断熱パネル10の横接続部22側の断熱材20の側端面と、他方の断熱パネル10の横接続凹部12側の断熱材20の側端面とが当接される。横方向で隣接する断熱パネル10は実部35同士が接続される。すなわち、隣接する断熱パネル10のうち、一方の断熱パネル10の外装材30の突状実部32が、他方の断熱パネル10の外装材30の受け実部31の表面に配設されて接続される。また断熱パネル10の突状実部32側の側端部は取付具40に係止される。この場合、一対の第二係止片45が外装材30の係止溝33に差し込まれる。   A plurality of heat insulation panels 10 are attached to the base wall 60 side by side. As shown in FIG. 7, the horizontal connection part 22 and the horizontal connection recessed part 12 are connected to the heat insulation panel 10 adjacent in the horizontal direction. That is, the horizontal connection part 22 of one heat insulation panel 10 is fitted in the horizontal connection recessed part 12 of the other heat insulation panel 10 among the heat insulation panels 10 adjacent in a horizontal direction. Further, the side end surface of the heat insulating material 20 on the side of the horizontal connection portion 22 of one heat insulating panel 10 and the side end surface of the heat insulating material 20 on the side of the horizontal connection recess 12 of the other heat insulating panel 10 are brought into contact. The real parts 35 are connected to the heat insulating panels 10 adjacent in the horizontal direction. That is, of the adjacent heat insulation panels 10, the protruding real part 32 of the exterior material 30 of one heat insulation panel 10 is disposed and connected to the surface of the receiving real part 31 of the exterior material 30 of the other heat insulation panel 10. The Further, the side end portion of the heat insulating panel 10 on the projecting real portion 32 side is locked to the fixture 40. In this case, the pair of second locking pieces 45 are inserted into the locking grooves 33 of the exterior material 30.

図8に土台部分を示す。土台部分には横胴縁61が設けられている。横胴縁61は角形鋼管等を横方向(水平方向)に長く配置して形成されている。横胴縁61はアンカーボルトなどの固定具14で下地壁60の表面に固定されている。横胴縁61には土台水切り15が取り付けられている。土台水切り15はビス等の固定具16で固定されている。土台水切り15の上側には支持具50が配設されている。以下、土台部分に設けられる支持具50を第一支持具50aという。この第一支持具50aは横胴縁61の表面側(屋外側)に設けられている。第一支持具50aは固着部52が横胴縁61に固着されている。この場合、ビス等の固定具17が固定孔54から横胴縁61にまで打ち込まれている。   FIG. 8 shows the base part. A horizontal trunk edge 61 is provided on the base portion. The horizontal trunk edge 61 is formed by arranging rectangular steel pipes or the like long in the horizontal direction (horizontal direction). The horizontal trunk edge 61 is fixed to the surface of the base wall 60 by a fixture 14 such as an anchor bolt. A base drainer 15 is attached to the horizontal trunk edge 61. The base drainer 15 is fixed by a fixing tool 16 such as a screw. A support 50 is disposed on the upper side of the base drainer 15. Hereinafter, the support 50 provided on the base portion is referred to as a first support 50a. The first support 50 a is provided on the surface side (outdoor side) of the horizontal trunk edge 61. The first support 50 a has a fixing portion 52 fixed to the horizontal trunk edge 61. In this case, the fixing tool 17 such as a screw is driven from the fixing hole 54 to the lateral trunk edge 61.

土台部分において、断熱パネル10は第一支持具50aにより支持されている。断熱パネル10の縦接続凹部11には横胴縁61が位置されている。断熱パネル10の外装材30の下端面は第一支持具50aの載置部56に載置されている。断熱パネル10の縦接続凹部11において、外装材30の下端部の裏面には第一支持具50aの位置決め部51の先端が当接している。断熱パネル10の縦接続凹部11において、断熱材20の下端面は横胴縁61の上面に近接あるいは荷重がかからない程度に接触している。これにより、外装材30に比べて剛性の低い断熱材20に断熱パネル10の重量がかかりにくくなる。従って、経時変化により断熱材20の変形や破損、断熱パネル10の脱落や位置ずれなどをほとんど無いようにすることができる。   In the base portion, the heat insulating panel 10 is supported by the first support 50a. A horizontal trunk edge 61 is located in the longitudinal connection recess 11 of the heat insulating panel 10. The lower end surface of the exterior member 30 of the heat insulation panel 10 is placed on the placement portion 56 of the first support 50a. In the longitudinal connection recessed part 11 of the heat insulation panel 10, the front-end | tip of the positioning part 51 of the 1st support tool 50a is contact | abutting on the back surface of the lower end part of the exterior material 30. FIG. In the longitudinal connection recess 11 of the heat insulating panel 10, the lower end surface of the heat insulating material 20 is in contact with the upper surface of the horizontal trunk edge 61 to the extent that no load is applied. Thereby, the weight of the heat insulation panel 10 is less likely to be applied to the heat insulating material 20 having a lower rigidity than the exterior material 30. Therefore, the heat insulating material 20 can be prevented from being deformed or damaged, and the heat insulating panel 10 can be omitted or displaced due to changes over time.

下地壁60には複数枚の断熱パネル10が縦方向に並べて取り付けられる。図9に示すように、縦方向で隣接する断熱パネル10は縦接続部21と縦接続凹部11とが接続される。すなわち、縦方向で隣接する断熱パネル10のうち、下側の断熱パネル10の縦接続部21が上側の断熱パネル10の縦接続凹部11に嵌合される。また下側の断熱パネル10の縦接続部21側の断熱材20の上端面と、上側の断熱パネル10の縦接続凹部11側の断熱材20の下端面とが当接される。下側の断熱パネル10の縦接続部21の表面にはプレート63が台座として設けられている。プレート63の表面には第一支持具50aとは別の支持具50が設けられている。以下、縦方向で隣接する断熱パネル10の接続部分に設けられる支持具50を第二支持具50bという。この第二支持具50bは固着部52が下地壁60に固着されている。この場合、ビス等の固定具65が固定孔54からプレート63を貫通して下地壁60にまで打ち込まれている。上側の断熱パネル10は第二支持具50bにより支持されている。上側の断熱パネル10の外装材30の下端面は第二支持具50bの載置部56に載置されている。断熱パネル10の縦接続凹部11において、外装材30の下端部の裏面には第二支持具50bの位置決め部51の先端が当接している。断熱パネル10の縦接続凹部11において、断熱材20の下端面は下側の断熱パネル10の断熱材20の上面に近接あるいは荷重がかからない程度に接触している。これにより、外装材30に比べて剛性の低い断熱材20に断熱パネル10の重量がかかりにくくなる。従って、経時変化により断熱材20の変形や破損、断熱パネル10の脱落や位置ずれなどをほとんど無いようにすることができる。また縦方向で隣接する外装材30の下端面と上端面との間にはシーリング66が設けられている。   A plurality of heat insulating panels 10 are attached to the base wall 60 side by side in the vertical direction. As shown in FIG. 9, the vertical connection portions 21 and the vertical connection recesses 11 are connected to the heat insulating panels 10 adjacent in the vertical direction. That is, among the heat insulation panels 10 adjacent in the vertical direction, the vertical connection portion 21 of the lower heat insulation panel 10 is fitted into the vertical connection recess 11 of the upper heat insulation panel 10. Further, the upper end surface of the heat insulating material 20 on the vertical connection portion 21 side of the lower heat insulating panel 10 and the lower end surface of the heat insulating material 20 on the vertical connection recess 11 side of the upper heat insulating panel 10 are brought into contact with each other. A plate 63 is provided as a pedestal on the surface of the vertical connection portion 21 of the lower heat insulation panel 10. A support member 50 different from the first support member 50 a is provided on the surface of the plate 63. Hereinafter, the support 50 provided in the connection part of the heat insulation panel 10 adjacent in the vertical direction is called the 2nd support 50b. The second support 50 b has a fixing portion 52 fixed to the base wall 60. In this case, a fixing tool 65 such as a screw is driven from the fixing hole 54 to the base wall 60 through the plate 63. The upper heat insulation panel 10 is supported by the second support 50b. The lower end surface of the exterior material 30 of the upper heat insulation panel 10 is placed on the placement portion 56 of the second support 50b. In the longitudinal connection recessed part 11 of the heat insulation panel 10, the front-end | tip of the positioning part 51 of the 2nd support tool 50b is in contact with the back surface of the lower end part of the exterior material 30. In the longitudinal connection recess 11 of the heat insulating panel 10, the lower end surface of the heat insulating material 20 is in contact with the upper surface of the heat insulating material 20 of the lower heat insulating panel 10 to the extent that no load is applied. Thereby, the weight of the heat insulation panel 10 is less likely to be applied to the heat insulating material 20 having a lower rigidity than the exterior material 30. Therefore, the heat insulating material 20 can be prevented from being deformed or damaged, and the heat insulating panel 10 can be omitted or displaced due to changes over time. Further, a sealing 66 is provided between the lower end surface and the upper end surface of the exterior material 30 adjacent in the vertical direction.

本実施の形態では、支持具50の通気孔57と断熱パネル10の通気溝24及び縦方向で隣接する断熱パネル10の通気溝24同士が連通して通気層が形成される。すなわち、通気層は、土台水切り15とその直上の外装材30の下端との隙間から、第一支持具50aの通気孔57と、第一支持具50aの直上の断熱パネル10の通気溝24と、この断熱パネル10の直上の第二支持具50bの通気孔57と、第二支持具50bの直上の断熱パネル10の通気溝24とが連通し、断熱壁の上端にまで達している。従って、上記断熱壁は空気が通気層を流通するので、内部結露が発生しにくくなる。   In the present embodiment, the vent hole 57 of the support member 50, the vent groove 24 of the heat insulating panel 10, and the vent grooves 24 of the heat insulating panel 10 adjacent in the vertical direction communicate with each other to form a vent layer. That is, the ventilation layer includes a ventilation hole 57 of the first support tool 50a and a ventilation groove 24 of the heat insulation panel 10 just above the first support tool 50a from the gap between the base drainer 15 and the lower end of the exterior material 30 just above it. The vent hole 57 of the second support tool 50b immediately above the heat insulation panel 10 communicates with the vent groove 24 of the heat insulation panel 10 directly above the second support tool 50b, and reaches the upper end of the heat insulation wall. Therefore, since air circulates through the ventilation layer in the heat insulating wall, internal condensation is unlikely to occur.

本実施の形態では、断熱パネル10を下地壁60に取り付けることで、断熱材20と外装材30とを一度に施工するができる。断熱パネル10には予め通気溝24が形成されているので、通気層の形成のために施工現場で断熱材20と外装材30を位置合わせする必要がなくなる。従って、本実施の形態では断熱パネル10の施工時の手間を軽減することができる。また本実施の形態では、取付具40が外装材30で覆われて見えにくくすることができ、断熱壁の外観の低下を低減することができる。また本実施の形態では、隣接する断熱パネル10の断熱材20の端面同士を隙間なく接触させることができ、断熱壁の断熱性の低下を少なくすることができる。また本実施の形態では、取付具40が断熱材20の表面に配置されるので、取付具40が下地壁60と直接接触することがなく、熱が取付具40を通じて下地壁60に伝導することが少なくなり、断熱壁の断熱性の低下を少なくすることができる。   In this Embodiment, the heat insulating material 20 and the exterior material 30 can be constructed at once by attaching the heat insulating panel 10 to the foundation wall 60. Since the ventilation groove 24 is formed in the heat insulating panel 10 in advance, it is not necessary to align the heat insulating material 20 and the exterior material 30 at the construction site in order to form a gas permeable layer. Therefore, in this Embodiment, the effort at the time of construction of the heat insulation panel 10 can be reduced. Moreover, in this Embodiment, the fixture 40 is covered with the exterior material 30, it can be made difficult to see, and the fall of the external appearance of a heat insulation wall can be reduced. Moreover, in this Embodiment, the end surfaces of the heat insulating material 20 of the adjacent heat insulation panel 10 can be contacted without gap, and the heat insulation fall of a heat insulation wall can be decreased. Moreover, in this Embodiment, since the fixture 40 is arrange | positioned on the surface of the heat insulating material 20, the fixture 40 does not contact the base wall 60 directly, but heat is conducted to the base wall 60 through the fixture 40. And the deterioration of the heat insulating property of the heat insulating wall can be reduced.

本発明では、図10に示すように、横接続部12と横接続凹部22とを設けないで断熱パネル10を形成することもできる。この場合、断熱パネル10は断熱材20の側端面と外装材30の側端面とが断熱パネル10の厚み方向で略揃った位置に形成される。また取付具40は断熱パネル10の側端面に当接して設けられる。取付具40の固定部41は下地壁60に直接接触して固定されている。取付具40の第二係止片45は隣接する断熱パネル10のうちの一方の外装材30の係止溝33に差し込まれる。取付具40の第一係止片44は隣接する断熱パネル10のうちの他方の外装材30の受け実部31に係止される。その他の構成は上記実施の形態と同様にして断熱壁が形成される。   In this invention, as shown in FIG. 10, the heat insulation panel 10 can also be formed without providing the horizontal connection part 12 and the horizontal connection recessed part 22. As shown in FIG. In this case, the heat insulating panel 10 is formed at a position where the side end surface of the heat insulating material 20 and the side end surface of the exterior material 30 are substantially aligned in the thickness direction of the heat insulating panel 10. The fixture 40 is provided in contact with the side end surface of the heat insulating panel 10. The fixing portion 41 of the fixture 40 is fixed in direct contact with the base wall 60. The second locking piece 45 of the fixture 40 is inserted into the locking groove 33 of one exterior material 30 of the adjacent heat insulating panels 10. The first locking piece 44 of the fixture 40 is locked to the receiving part 31 of the other exterior member 30 of the adjacent heat insulating panels 10. In other configurations, the heat insulating wall is formed in the same manner as in the above embodiment.
