Description

本発明は、断熱構造及び断熱方法に関する。 The present invention relates to a heat insulating structure and a heat insulating method.

下記特許文献１には、建物の出隅部に設けられた柱に断熱材を貼り付けて、外壁出隅部に熱橋による結露が発生することを抑制する、建物の外壁出隅部構造が記載されている。 Patent Document 1 below describes a structure for an exterior wall corner of a building in which a heat insulating material is attached to a pillar provided at the corner of the building to suppress condensation due to a thermal bridge at the corner of the exterior wall. Are listed.

特開２０１０－１５６１１９号公報Japanese Patent Application Publication No. 2010-156119

上記特許文献１の外壁出隅部構造のように、柱を断熱材で被覆することは熱橋を抑制するために有効である。特に建物の出隅部は、２方向から外気に晒されることに起因して熱橋が生じやすいため、断熱性能を向上することが求められている。そこで、建物の出隅部の断熱性能を向上するために、出隅部の柱には、上記特許文献１に示されたような屋外側の断熱材に加えて、屋内側にも断熱材を敷設することが考えられる。 Covering the pillars with a heat insulating material, as in the external wall protruding corner structure of Patent Document 1, is effective for suppressing thermal bridges. In particular, the projecting corners of buildings are exposed to the outside air from two directions and are prone to thermal bridges, so there is a need to improve their insulation performance. Therefore, in order to improve the insulation performance of the projecting corners of a building, in addition to the outdoor insulation material as shown in Patent Document 1, the pillars at the projecting corners are also provided with insulation material on the indoor side. It is possible to install it.

しかしながら、建物の柱は下柱と上柱とを連結して形成する場合が多く、このような場合においては、柱部材の連結部と断熱材との干渉により、連結部の施工や断熱材の配置が困難となることがある。 However, building columns are often formed by connecting a lower column and an upper column, and in such cases, interference between the connecting part of the column member and the insulation material makes it difficult to install the connecting part or replace the insulation material. Placement may be difficult.

本発明は、上記事実を考慮して、柱及び断熱材の施工がし易い断熱構造及び断熱方法を提供することを目的とする。 The present invention takes the above-mentioned facts into consideration and aims to provide a heat insulating structure and a heat insulating method that are easy to construct columns and heat insulating materials.

第一態様の断熱構造は、建物の出隅部に配置され、上下方向に配置された下柱と上柱とを備えて形成された柱と、前記下柱及び前記上柱それぞれの屋内側の面に配置され、前記下柱と前記上柱とを連結する連結部材と、前記柱の屋外側の隣り合う２面を被覆する外側断熱材と、前記外側断熱材を前記柱に固定する固定部材と、前記外側断熱材とは別部材で形成されると共に、前記外側断熱材と接して配置され、前記柱の屋内側の２面を被覆する内側断熱材と、を有する。 The heat insulation structure of the first aspect includes a column that is arranged at a projecting corner of a building and includes a lower column and an upper column arranged in the vertical direction, and a column on the indoor side of each of the lower column and the upper column. a connecting member arranged on a surface and connecting the lower column and the upper column; an outer heat insulating material covering two adjacent outdoor sides of the column; and a fixing member fixing the outer heat insulating material to the column. and an inner heat insulating material formed of a separate member from the outer heat insulating material, disposed in contact with the outer heat insulating material, and covering two surfaces of the column on the indoor side.

第一態様の断熱構造では、建物の出隅部に配置された柱の屋外側の２面が外側断熱材で被覆されている。また、柱の屋内側の２面も、内側断熱材で被覆されている。この内側断熱材は、外側断熱材と接して配置されている。このため、建物の出隅部において、柱の屋外側から屋内側にかけて、連続した断熱層が形成される。これにより、熱橋が生じやすい建物の出隅部の断熱性を高めることができる。 In the first aspect of the heat insulation structure, the two outdoor sides of the pillars placed at the projecting corners of the building are covered with an outer heat insulating material. In addition, the two indoor sides of the pillar are also covered with inner heat insulating material. This inner insulation material is arranged in contact with the outer insulation material. Therefore, a continuous heat insulating layer is formed from the outdoor side of the pillar to the indoor side at the projecting corner of the building. This makes it possible to improve the insulation of the projecting corners of the building where thermal bridges are likely to occur.

また、この断熱構造では、外側断熱材と内側断熱材とが別体で形成されている。このため、断熱材の施工時期を、外側と内側とでずらすことができる。これにより、例えば下柱及び上柱の屋外側の面に外側断熱材を配置して、下柱と上柱とを連結部材で連結し、その後、下柱及び上柱それぞれの屋内側の面に内側断熱材を配置する、といった工程を採用できる。このような工程を踏まえると、下柱と上柱との連結部の施工すなわち柱の施工及び断熱材の施工が容易である。 Moreover, in this heat insulation structure, the outer heat insulating material and the inner heat insulating material are formed separately. Therefore, the construction timing of the insulation material can be staggered between the outside and the inside. With this, for example, the outer insulation material is placed on the outdoor side surfaces of the lower column and the upper column, the lower column and the upper column are connected with the connecting member, and then the indoor side surfaces of the lower column and the upper column are connected. A process such as placing internal insulation material can be adopted. Based on such a process, construction of the connecting portion between the lower column and the upper column, that is, construction of the column and construction of the heat insulating material is easy.

これに対して、仮に、外側断熱材と内側断熱材とが一体的に形成されている場合、断熱材の施工後に下柱と上柱とを連結しようとしても、連結部材が断熱材と干渉して連結し難い。あるいは、下柱及び上柱の連結後に断熱材を施工しようとしても、柱の屋外側に足場を組んで屋外側から作業したり、屋内側から柱の屋外側へ手を伸ばして作業したりする必要があり、作業性が悪い。 On the other hand, if the outer insulation material and the inner insulation material are integrally formed, even if you try to connect the lower pillar and the upper pillar after installing the insulation material, the connecting member will interfere with the insulation material. difficult to connect. Alternatively, if you try to install insulation material after connecting the lower and upper columns, you may have to erect scaffolding on the outdoor side of the column and work from the outdoor side, or reach from the indoor side to the outdoor side of the column. It is necessary and the workability is poor.

また、外側断熱材と内側断熱材とが一体的に形成されている場合、柱の屋外側から屋内側へ断熱材を折り曲げて施工するため、この折り曲げた部分の厚みが薄くなり、他の部分より断熱性が劣る可能性がある。これに対して、外側断熱材と内側断熱材とが別体で形成されていれば、このような折り曲げによる断熱性の劣化が生じることを抑制できる。 In addition, when the outer insulation material and the inner insulation material are integrally formed, the insulation material is folded from the outdoor side of the column to the indoor side, so the thickness of this bent part becomes thinner, and the thickness of the other parts becomes thinner. The insulation properties may be worse. On the other hand, if the outer heat insulating material and the inner heat insulating material are formed separately, it is possible to suppress the deterioration of the heat insulation properties due to such bending.

第二態様の断熱構造は、第一態様に記載の断熱構造において、前記固定部材は、前記柱に塗布された接着剤である。 A heat insulating structure according to a second aspect is the heat insulating structure according to the first aspect, in which the fixing member is an adhesive applied to the column.

第二態様の断熱構造では、外側断熱材を柱に固定する固定部材が接着剤である。接着剤は面状に塗布されるため、外側断熱材を柱に対して面で支持できる。これにより外側断熱材を安定的に保持し易い。 In the second aspect of the heat insulation structure, the fixing member that fixes the outer heat insulator to the pillar is an adhesive. Since the adhesive is applied in a planar manner, the outer insulation can be supported in a planar manner to the columns. This makes it easier to stably hold the outer heat insulating material.

第三態様の断熱構造は、第一態様に記載の断熱構造において、前記固定部材は、前記柱に接合され、前記柱の屋外側へ突出した複数の棒状部材であり、前記棒状部材は前記外側断熱材を貫通している。 A third aspect of the heat insulating structure is the heat insulating structure according to the first aspect, in which the fixing member is a plurality of rod-shaped members that are joined to the column and protrude toward the outdoor side of the column, and the rod-shaped members are connected to the outside of the column. Penetrates the insulation.

第三態様の断熱構造では、外側断熱材を柱に固定する固定部材が、柱に接合され、柱の屋外側へ突出した複数の棒状部材である。 In the third aspect of the heat insulation structure, the fixing members that fix the outer heat insulating material to the columns are a plurality of rod-shaped members that are joined to the columns and protrude toward the outdoor side of the columns.

この棒状部材は外側断熱材を貫通している。このような棒状部材によって外側断熱材を支持すると、外側断熱材の荷重が、棒状部材に作用する。棒状部材の剛性が十分に高ければ、外側断熱材に厚みや重量がある場合でも、外側断熱材が自重によってずり変形することが抑制される。このため、断熱性を保持し易い。 This rod-shaped member passes through the outer insulation material. When the outer heat insulating material is supported by such a rod-like member, the load of the outer heat insulating material acts on the rod-like member. If the rigidity of the rod-shaped member is sufficiently high, even if the outer heat insulating material is thick and heavy, the outer heat insulating material is prevented from shearing and deforming due to its own weight. Therefore, it is easy to maintain heat insulation properties.

第四態様の断熱構造は、第一態様に記載の断熱構造において、前記固定部材は、前記柱に接合された木下地材と、前記木下地材に挿入され、前記柱の屋外側へ突出した複数の棒状部材と、を備え、前記棒状部材は前記外側断熱材を貫通している。 The heat insulation structure according to a fourth aspect is the heat insulation structure according to the first aspect, in which the fixing member is inserted into the wood base material joined to the column and the wood base material and protrudes toward the outdoor side of the column. a plurality of rod-like members, the rod-like members passing through the outer heat insulating material.

第四態様の断熱構造では、柱に接合された木下地材と、木下地材に挿入され、柱の屋外側へ突出した複数の棒状部材と、を備えている。 The fourth aspect of the heat insulation structure includes a wood base material joined to a column, and a plurality of rod-shaped members inserted into the wood base material and protruding toward the outdoor side of the column.

この棒状部材は、外側断熱材を貫通している。このような棒状部材によって外側断熱材を支持すると、外側断熱材の荷重が、棒状部材に作用する。棒状部材の剛性が十分に高ければ、外側断熱材に厚みや重量がある場合でも、外側断熱材が自重によってずり変形することが抑制される。このため、断熱性を保持し易い。 This rod-shaped member passes through the outer heat insulating material. When the outer heat insulating material is supported by such a rod-like member, the load of the outer heat insulating material acts on the rod-like member. If the rigidity of the rod-shaped member is sufficiently high, even if the outer heat insulating material is thick and heavy, the outer heat insulating material is prevented from shearing and deforming due to its own weight. Therefore, it is easy to maintain heat insulation properties.

また、この棒状部材は、木下地材に挿入されている。木製の下地材は鋼製の下地材と比較して柔らかいため、ビス、釘、ステープルなど各種の棒状部材を挿入して固定し易い。このため様々な種類の棒状部材を用いることができ、汎用性が高い。 Moreover, this rod-shaped member is inserted into the wood base material. Wooden base material is softer than steel base material, so it is easier to insert and fix various rod-shaped members such as screws, nails, and staples. Therefore, various types of rod-shaped members can be used, and the versatility is high.

第五態様の断熱方法は、柱の上側を形成する上柱の隣り合う２面に外側断熱材を固定して被覆する工程と、柱の下側を形成する下柱の隣り合う２面に外側断熱材を固定して被覆する工程と、建物の出隅部に前記下柱を設置する工程と、前記下柱の屋内側の面及び前記上柱の屋内側の面に連結部材を配置して、前記下柱と上柱とを連結し、柱を形成する工程と、前記柱の屋内側の２面を内側断熱材で被覆して、前記外側断熱材と前記内側断熱材とが連続した断熱層を形成する工程と、を有する。 The heat insulation method of the fifth aspect includes a step of fixing and covering two adjacent surfaces of the upper column that forms the upper side of the column with an outer heat insulating material, and a step of fixing and covering the outer heat insulating material on two adjacent surfaces of the lower column that forms the lower side of the column. a step of fixing and covering a heat insulating material, a step of installing the lower column at an outgoing corner of the building, and arranging a connecting member on an indoor side surface of the lower column and an indoor side surface of the upper column. , a step of connecting the lower column and the upper column to form a column, and coating two indoor sides of the column with an inner heat insulating material so that the outer heat insulating material and the inner heat insulating material are continuous. forming a layer.

第五態様の断熱方法では、建物の出隅部に配置される柱の屋外側の２面が外側断熱材で被覆される。また、柱の屋内側の２面も、内側断熱材で被覆される。これらの外側断熱材と内側断熱材とは、連続した断熱層を形成する。このため、建物の出隅部において、柱の屋外側から屋内側にかけて、連続した断熱層が形成される。これにより、熱橋が生じやすい建物の出隅部の断熱性を高めることができる。 In the fifth aspect of the heat insulation method, the two outdoor sides of the pillars placed at the projecting corners of the building are covered with an outer heat insulating material. In addition, the two indoor sides of the pillar are also covered with inner heat insulating material. These outer and inner insulation materials form a continuous insulation layer. Therefore, a continuous heat insulating layer is formed from the outdoor side of the pillar to the indoor side at the projecting corner of the building. This makes it possible to improve the insulation of the projecting corners of the building where thermal bridges are likely to occur.

また、この断熱方法では、断熱材の施工時期が、外側と内側とでずらされている。具体的には、下柱及び上柱それぞれの屋外側の面に外側断熱材を配置して、下柱と上柱とを連結部材で連結し、その後、下柱及び上柱それぞれの屋内側の面に内側断熱材を配置している。このような工程を踏まえると、下柱と上柱との連結部の施工、すなわち柱の施工及び断熱材の施工が容易である。 Moreover, in this insulation method, the construction timing of the insulation material is staggered between the outside and the inside. Specifically, external insulation material is placed on the outdoor side of each of the lower and upper columns, the lower and upper columns are connected with a connecting member, and then the indoor side of each of the lower and upper columns is connected. Internal insulation is placed on the surface. Based on such a process, construction of the connecting portion between the lower column and the upper column, that is, construction of the column and construction of the heat insulating material is easy.

これに対して、仮に、外側断熱材と内側断熱材とが一体的に形成されている場合、断熱材の施工後に下柱と上柱とを連結しようとしても、連結部材が断熱材と干渉して連結し難い。あるいは、下柱及び上柱の連結後に断熱材を施工しようとしても、柱の屋外側に足場を組んで屋外側から作業したり、屋内側から柱の屋外側へ手を伸ばして作業したりする必要があり、作業性が悪い。 On the other hand, if the outer insulation material and the inner insulation material are integrally formed, even if you try to connect the lower pillar and the upper pillar after installing the insulation material, the connecting member will interfere with the insulation material. difficult to connect. Alternatively, if you try to install insulation material after connecting the lower and upper columns, you may have to erect scaffolding on the outdoor side of the column and work from the outdoor side, or reach from the indoor side to the outdoor side of the column. It is necessary and the workability is poor.

また、外側断熱材と内側断熱材とが一体的に形成されている場合、柱の屋外側から屋内側へ断熱材を折り曲げて施工するため、この折り曲げた部分の厚みが薄くなり、他の部分より断熱性が劣る可能性がある。これに対して、外側断熱材と内側断熱材とが別体で形成されていれば、このような折り曲げによる断熱性の劣化が生じることを抑制できる。 In addition, when the outer insulation material and the inner insulation material are integrally formed, the insulation material is folded from the outdoor side of the column to the indoor side, so the thickness of this bent part becomes thinner, and the thickness of the other parts becomes thinner. The insulation properties may be worse. On the other hand, if the outer heat insulating material and the inner heat insulating material are formed separately, it is possible to suppress the deterioration of the heat insulation properties due to such bending.

図１に示すように、外側断熱材３０は、柱１２の屋外側の隣り合う２面を被覆する断熱材であり、一例として、グラスウールやロックウール等がフィルムに被覆されて形成された袋状断熱材である。 (Outer insulation material)
As shown in FIG. 1, the outer heat insulating material 30 is a heat insulating material that covers two adjacent outdoor sides of the pillar 12, and is, for example, a bag-shaped material formed by covering glass wool, rock wool, etc. with a film. It is an insulator.

なお、外側断熱材３０は、必ずしも袋状に形成しなくてもよく、フィルムを用いずに繊維が露出したものとしてもよい。また、外側断熱材３０は、グラスウールやロックウール等が板状に成形された断熱材としてもよい。 Note that the outer heat insulating material 30 does not necessarily have to be formed into a bag shape, and may have exposed fibers without using a film. Further, the outer heat insulating material 30 may be a heat insulating material made of glass wool, rock wool, or the like formed into a plate shape.

外側断熱材３０は、柱１２において屋外に面する一方側の面（Ｘ方向に沿う面）から他方側の面（Ｙ方向に沿う面）に亘って巻き付けて配置されている。また、外側断熱材３０は、柱１２の屋外側の両面の全面を被覆している。 The outer heat insulating material 30 is arranged so as to be wrapped around the pillar 12 from one surface facing outdoors (the surface along the X direction) to the other surface (the surface along the Y direction). Further, the outer heat insulating material 30 covers the entire surface of both sides of the column 12 on the outdoor side.

なお、「全面を被覆」とは、図１に示すように、外側断熱材３０が、柱１２を平面視した場合に、Ｘ方向及びＹ方向に沿う面の全面を被覆している状態を示している。上下方向であるＺ方向においては、部分的に外側断熱材３０が配置されない間欠部を有していてもよい。 Note that "covering the entire surface" refers to a state in which the outer heat insulating material 30 covers the entire surface along the X direction and the Y direction when the column 12 is viewed from above, as shown in FIG. ing. In the Z direction, which is the vertical direction, there may be an intermittent portion where the outer heat insulating material 30 is not disposed.

さらに、外側断熱材３０は、Ｘ方向に沿う部分とＹ方向に沿うそれぞれの部分が、柱１２の外側へ延長して配置され、延長された部分が、後述する内側断熱材５０と接して配置されている。 Furthermore, the outer heat insulating material 30 is arranged such that a portion along the X direction and a portion along the Y direction are extended to the outside of the pillar 12, and the extended portion is arranged in contact with the inner heat insulating material 50, which will be described later. has been done.

また、図３に示すように、柱１２における下柱１４を覆う外側断熱材３０と、上柱１６を覆う外側断熱材３０とは別体とされ、互いに接して配置されている。 Further, as shown in FIG. 3, the outer heat insulating material 30 that covers the lower column 14 of the column 12 and the outer heat insulating material 30 that covers the upper column 16 are separate bodies and are arranged in contact with each other.

なお、後述する断熱材３０Ａ及び３０Ｂ（図５参照）のように、外側断熱材３０は、柱１２におけるＸ方向に沿う面を覆う部材とＹ方向に沿う面を覆う部材とを分けて形成してもよい。 Note that, like heat insulating materials 30A and 30B (see FIG. 5) described later, the outer heat insulating material 30 is formed by separately forming a member covering a surface along the X direction of the column 12 and a member covering a surface along the Y direction. It's okay.

（固定部材）
固定部材４０は、柱１２（下柱１４及び上柱１６）に塗布された接着剤である。固定部材４０は、柱１２の屋外側の両面の全面に塗布されている。これにより、柱１２と外側断熱材３０とが面接触する。 (Fixed member)
The fixing member 40 is an adhesive applied to the columns 12 (lower column 14 and upper column 16). The fixing member 40 is applied to both surfaces of the column 12 on the outdoor side. Thereby, the pillar 12 and the outer heat insulating material 30 come into surface contact.

なお、「全面に塗布」とは、図１に示すように、固定部材４０が、柱１２を平面視した場合に、Ｘ方向及びＹ方向に沿う面の全面に塗布されている状態を示している。上下方向であるＺ方向においては、部分的に固定部材４０が塗布されない間欠部を有していてもよい。 It should be noted that "applied to the entire surface" refers to a state in which the fixing member 40 is applied to the entire surface along the X direction and the Y direction when the pillar 12 is viewed from above, as shown in FIG. There is. In the Z direction, which is the vertical direction, there may be intermittent portions where the fixing member 40 is not applied.

（内側断熱材）
内側断熱材５０は、柱１２の屋内側の隣り合う２面をそれぞれ被覆する断熱材であり、グラスウールやロックウール等がフィルムに被覆されて形成された袋状断熱材である。なお、内側断熱材５０は、必ずしも袋状に形成しなくてもよく、フィルムを用いずに繊維が露出したものとしてもよい。 (inner insulation material)
The inner heat insulating material 50 is a heat insulating material that covers two adjacent surfaces of the column 12 on the indoor side, and is a bag-shaped heat insulating material formed by covering glass wool, rock wool, or the like with a film. Note that the inner heat insulating material 50 does not necessarily have to be formed into a bag shape, and may have exposed fibers without using a film.

柱１２の屋内側の一方の面と他方の面とは、それぞれ別体の内側断熱材５０で被覆されている。また、内側断熱材５０は、外側断熱材３０とは別部材で形成されると共に、外側断熱材３０と接して配置されている。なお、内側断熱材５０は、柱１２において屋内側の面の「全面」を被覆する必要はなく、少なくとも外側断熱材３０寄りの部分を被覆していればよい。 One surface and the other surface of the column 12 on the indoor side are covered with separate inner heat insulating materials 50, respectively. Furthermore, the inner heat insulating material 50 is formed of a separate member from the outer heat insulating material 30 and is disposed in contact with the outer heat insulating material 30. Note that the inner heat insulating material 50 does not need to cover the "entire surface" of the indoor side surface of the pillar 12, but only needs to cover at least a portion closer to the outer heat insulating material 30.

内側断熱材５０は、平面視で連結部材２０と重なる位置に配置されている。内側断熱材５０は、図３（Ａ）に示すように、下柱１４と上柱１６との境界部分で分割して形成し、下側の内側断熱材５０と上側の内側断熱材５０とで、連結部材２０を上下方向に挟む構成とすることができる。 The inner heat insulating material 50 is arranged at a position overlapping the connecting member 20 in a plan view. As shown in FIG. 3(A), the inner heat insulating material 50 is formed by being divided at the boundary between the lower column 14 and the upper column 16, and is formed by the lower inner insulating material 50 and the upper inner insulating material 50. , the connecting member 20 may be sandwiched in the vertical direction.

また、内側断熱材５０は、図３（Ｂ）に示すように、下柱１４と上柱１６との境界部分で連続して形成し、連結部材２０、固定片１４Ｂ及び１６Ｂと干渉する部分を変形させて、連結部材２０、固定片１４Ｂ及び１６Ｂを上下方向に挟む構成とすることもできる。 Further, as shown in FIG. 3(B), the inner heat insulating material 50 is formed continuously at the boundary between the lower column 14 and the upper column 16, and has a portion that interferes with the connecting member 20 and the fixed pieces 14B and 16B. It is also possible to modify the structure so that the connecting member 20 and the fixing pieces 14B and 16B are sandwiched in the vertical direction.

内側断熱材５０を変形させるためには、作業員が手指を用いて、連結部材２０の形状に沿うように形を調整してもよいし、内側断熱材５０に切り込みを入れて変形させ易くしてもよい。 In order to deform the inner heat insulating material 50, the worker may use his or her fingers to adjust the shape to follow the shape of the connecting member 20, or make a cut in the inner heat insulating material 50 to make it easier to deform. It's okay.

なお、図１に二点鎖線で示すように、柱１２には、梁１８が接合されている。内側断熱材５０は、この梁１８と干渉する部分で分割させたり、適宜変形させたりして用いることができる。内側断熱材５０を梁１８と干渉する部分で分割すれば、内側断熱材５０を梁１８に載置して保持することができる。すなわち、内側断熱材５０は、梁１８の位置に応じて、形状を適宜変更することができる。 Note that a beam 18 is joined to the column 12, as shown by the two-dot chain line in FIG. The inner heat insulating material 50 can be used by being divided at a portion where it interferes with the beam 18 or by being appropriately deformed. By dividing the inner heat insulating material 50 at the portion that interferes with the beam 18, the inner heat insulating material 50 can be placed and held on the beam 18. That is, the shape of the inner heat insulating material 50 can be changed as appropriate depending on the position of the beam 18.

（その他の構成）
柱１２の屋外側には、外壁パネル６０が配置されている。外壁パネル６０は、柱１２と間隔を空けて配置され、この柱１２と外壁パネル６０との間に、外側断熱材３０が配置されている。外壁パネル６０は、固定部材６０Ａに固定されている。固定部材６０Ａは、図示しない連結部材を用いて、柱１２又は梁１８に連結され、保持されている。 (Other configurations)
An outer wall panel 60 is arranged on the outdoor side of the pillar 12. The outer wall panel 60 is spaced apart from the pillar 12, and the outer heat insulating material 30 is arranged between the pillar 12 and the outer wall panel 60. The outer wall panel 60 is fixed to a fixing member 60A. The fixing member 60A is connected to and held by the pillar 12 or the beam 18 using a connecting member (not shown).

また、内側断熱材５０には、壁体断熱材６２及び６４が接して配置されている。壁体断熱材６２及び６４は、建物１０における外壁（屋外に面した壁体）の内部に配置された断熱材であり、外壁の略全面に亘って配置されている。壁体断熱材６２は袋状断熱材であり、壁体断熱材６２の外側に配置された壁体断熱材６４は板状断熱材である。 Further, wall heat insulating materials 62 and 64 are arranged in contact with the inner heat insulating material 50. The wall heat insulating materials 62 and 64 are heat insulating materials disposed inside the outer wall (wall facing outdoors) of the building 10, and are disposed over substantially the entire surface of the outer wall. The wall heat insulating material 62 is a bag-like heat insulating material, and the wall heat insulating material 64 disposed outside the wall heat insulating material 62 is a plate-like heat insulating material.

内側断熱材５０と壁体断熱材６２及び６４とが接して配置されることにより、建物１０の出隅部を含む外周部には、断熱材が連続して配置される。 By disposing the inner heat insulating material 50 and the wall heat insulating materials 62 and 64 in contact with each other, the heat insulating material is continuously disposed around the outer peripheral portion of the building 10 including the projecting corners.

なお、壁体断熱材６４と外壁パネル６０とは間隔を空けて配置されている。この部分には、断熱材をさらに配置してもよいし、配置しなくてもよい。 Note that the wall heat insulating material 64 and the outer wall panel 60 are spaced apart from each other. A heat insulating material may or may not be further disposed in this portion.

＜断熱方法＞
上述した断熱構造を形成する方法としての断熱方法について説明する。断熱構造を形成するためには、まず、図４（Ａ）に示すように、柱１２の上側を形成する上柱１６の隣り合う２面に、接着剤である固定部材４０を塗布する。固定部材４０は、固定片１６Ｂが設けられていない面に塗布される。そして、この固定部材４０によって上柱１６に外側断熱材３０が固定され被覆される。 <Insulation method>
A heat insulation method as a method of forming the above-mentioned heat insulation structure will be explained. In order to form a heat insulating structure, first, as shown in FIG. 4A, a fixing member 40, which is an adhesive, is applied to two adjacent surfaces of the upper column 16 that forms the upper side of the column 12. The fixing member 40 is applied to the surface where the fixing piece 16B is not provided. The outer heat insulating material 30 is fixed to and covered with the upper column 16 by this fixing member 40.

次に、図４（Ｂ）に示すように、外壁パネル６０を、固定部材６０Ａに固定する。これにより、図４（Ｃ）に二点鎖線で示すように、外壁パネル６０と上柱１６との間に外側断熱材３０が保持された建物ユニット１０Ａが形成される。建物ユニット１０Ａは、図４（Ｃ）に二点鎖線で示すように、建物１０（図１参照）の出隅部を含む箱型ユニットであり、工場において製造され、建物１０の建設現場へ搬入される。 Next, as shown in FIG. 4(B), the outer wall panel 60 is fixed to the fixing member 60A. As a result, a building unit 10A is formed in which the outer heat insulating material 30 is held between the outer wall panel 60 and the upper pillar 16, as shown by the two-dot chain line in FIG. 4(C). The building unit 10A is a box-shaped unit that includes the projecting corner of the building 10 (see FIG. 1), as shown by the two-dot chain line in FIG. 4(C), and is manufactured in a factory and transported to the construction site of the building 10. be done.

図示は省略するが、同様に、柱１２の下側を形成する下柱１４（図２参照）の隣り合う２面にも、外側断熱材３０が固定され被覆される。そして外壁パネル６０を含む建物ユニットを形成し、建物１０の建設現場へ搬入する。 Although not shown, the outer heat insulating material 30 is similarly fixed and covered on two adjacent surfaces of the lower column 14 (see FIG. 2) forming the lower side of the column 12. A building unit including the outer wall panel 60 is then formed and transported to the construction site of the building 10.

その後、建物１０の出隅部に、下柱１４を含む建物ユニットを設置する。換言すると、下柱１４を含む建物ユニットが設置され、建物１０の出隅部が形成される。そして、下柱１４を含む建物ユニットの上方に、上柱１６を含む建物ユニット１０Ａを配置する。そして、下柱１４の屋内側の面及び上柱１６の屋内側の面に連結部材２０を配置して、下柱１４と上柱１６とを連結し、柱１２を形成する。 Thereafter, a building unit including the lower pillar 14 is installed at the projecting corner of the building 10. In other words, the building unit including the lower pillar 14 is installed, and the projecting corner of the building 10 is formed. Then, the building unit 10A including the upper pillar 16 is placed above the building unit including the lower pillar 14. Then, the connecting member 20 is arranged on the indoor side surface of the lower column 14 and the indoor side surface of the upper column 16 to connect the lower column 14 and the upper column 16 to form the column 12.

次に、図４（Ｄ）に示すように、柱１２の屋内側の２面を内側断熱材５０で被覆して、図４（Ｅ）に示すように、外側断熱材３０と内側断熱材５０とが連続した断熱層を形成する。その後、壁体断熱材６４等を順次配置して、建物１０を施工する。 Next, as shown in FIG. 4(D), two surfaces of the column 12 on the indoor side are covered with an inner insulating material 50, and as shown in FIG. 4(E), the outer insulating material 30 and the inner insulating material 50 are form a continuous heat insulating layer. Thereafter, the wall heat insulating material 64 and the like are sequentially arranged, and the building 10 is constructed.

＜作用及び効果＞
本開示の断熱構造では、図１に示すように、建物１０の出隅部に配置された柱１２の屋外側の２面が外側断熱材３０で被覆されている。また、柱１２の屋内側の２面も、内側断熱材５０で被覆されている。この内側断熱材５０は、外側断熱材３０と接して配置されている。このため、建物１０の出隅部において、柱１２の屋外側から屋内側にかけて、連続した断熱層が形成される。これにより、熱橋が生じやすい建物１０の出隅部の断熱性を高めることができる。 <Action and effect>
In the heat insulation structure of the present disclosure, as shown in FIG. 1, the two outdoor sides of the pillars 12 arranged at the projecting corners of the building 10 are covered with the outer heat insulating material 30. Further, the two indoor sides of the pillar 12 are also covered with an inner heat insulating material 50. This inner heat insulating material 50 is placed in contact with the outer heat insulating material 30. Therefore, a continuous heat insulating layer is formed at the projecting corner of the building 10 from the outdoor side of the pillar 12 to the indoor side. Thereby, it is possible to improve the heat insulation properties of the projecting corners of the building 10 where thermal bridges are likely to occur.

また、この断熱構造では、外側断熱材３０と内側断熱材５０とが別体で形成されている。このため、図４を用いて説明したように、断熱材の施工時期を、外側と内側とでずらすことができる。すなわち、例えば下柱１４及び上柱１６それぞれの屋外側の面に外側断熱材３０を配置して（図４（Ａ）参照）、下柱１４と上柱１６とを連結部材２０で連結し（図４（Ｃ）参照）、その後、下柱１４及び上柱１６の屋内側の面に内側断熱材５０を配置する（図４（Ｄ）参照）、といった工程を採用できる。このような工程を踏まえると、下柱１４と上柱１６との連結部の施工すなわち柱１２の施工及び断熱材（外側断熱材３０及び内側断熱材５０）の施工が容易である。 Moreover, in this heat insulation structure, the outer heat insulating material 30 and the inner heat insulating material 50 are formed separately. For this reason, as explained using FIG. 4, the construction timing of the heat insulating material can be shifted between the outside and the inside. That is, for example, the outer heat insulating material 30 is arranged on the outdoor side surface of each of the lower column 14 and the upper column 16 (see FIG. 4(A)), and the lower column 14 and the upper column 16 are connected by the connecting member 20 ( (see FIG. 4(C)), and then arrange the inner heat insulating material 50 on the indoor side surfaces of the lower column 14 and the upper column 16 (see FIG. 4(D)). Based on such a process, it is easy to construct the connecting portion between the lower column 14 and the upper column 16, that is, to construct the column 12 and to construct the heat insulating material (the outer heat insulating material 30 and the inner heat insulating material 50).

これに対して、仮に、外側断熱材３０と内側断熱材５０とが一体的に形成されている場合（比較例）、断熱材の施工後に下柱１４と上柱１６とを連結しようとしても、連結部材２０が断熱材と干渉して連結し難い。あるいは、下柱１４及び上柱１６の連結後に断熱材を施工しようとしても、柱１２の屋外側に足場を組んで屋外側から作業したり、屋内側から柱１２の屋外側へ手を伸ばして作業したりする必要があり、作業性が悪い。 On the other hand, if the outer insulating material 30 and the inner insulating material 50 are integrally formed (comparative example), even if you try to connect the lower column 14 and the upper column 16 after installing the insulating material, The connecting member 20 interferes with the heat insulating material, making it difficult to connect. Alternatively, even if you try to install insulation material after connecting the lower column 14 and the upper column 16, you may have to erect scaffolding on the outdoor side of the column 12 and work from the outdoor side, or reach from the indoor side to the outdoor side of the column 12. You need to do some work, and the workability is poor.

また、外側断熱材３０と内側断熱材５０とが一体的に形成されている場合（比較例）、柱１２の屋外側から屋内側へ断熱材を折り曲げて施工するため、この折り曲げた部分の厚みが薄くなり、他の部分より断熱性が劣る可能性がある。これに対して、本開示のように、外側断熱材３０と内側断熱材５０とが別体で形成されていれば、このような折り曲げによる断熱性の劣化が生じることを抑制できる。 In addition, when the outer heat insulating material 30 and the inner heat insulating material 50 are integrally formed (comparative example), since the heat insulating material is folded from the outdoor side of the column 12 to the indoor side, the thickness of this bent portion is may become thinner and have poorer insulation properties than other parts. On the other hand, if the outer heat insulating material 30 and the inner heat insulating material 50 are formed separately as in the present disclosure, it is possible to suppress the deterioration of the heat insulating properties due to such bending.

また、本開示の断熱構造では、外側断熱材３０を柱１２に固定する固定部材が接着剤である。接着剤は面状に塗布されるため、外側断熱材３０を柱１２に対して面で支持できる。これにより外側断熱材３０を安定的に保持し易い。 Further, in the heat insulation structure of the present disclosure, the fixing member that fixes the outer heat insulating material 30 to the pillar 12 is an adhesive. Since the adhesive is applied in a planar manner, the outer heat insulating material 30 can be supported on the pillar 12 in a planar manner. This makes it easier to stably hold the outer heat insulating material 30.

＜変形例＞
（第１変形例）
上記実施形態においては、固定部材４０を接着剤としているが、本開示の実施形態はこれに限らない。例えば図５に示すように、木桟７２、ビス７４及び７６で形成された固定部材７０を用いてもよい。なお、木桟７２は本開示における木下地材の一例であり、ビス７４は本開示における棒状部材の一例である。 <Modified example>
(First modification)
In the above embodiment, the fixing member 40 is made of adhesive, but the embodiments of the present disclosure are not limited to this. For example, as shown in FIG. 5, a fixing member 70 formed of a wooden crosspiece 72 and screws 74 and 76 may be used. Note that the wooden crosspiece 72 is an example of a wooden base material in the present disclosure, and the screw 74 is an example of a rod-shaped member in the present disclosure.

木桟７２は、ビス７６を用いて柱１２に接合されている。ビス７４は、木桟７２に挿入され、柱１２の屋外側へ突出している、また、ビス７４は、外側断熱材３０を貫通している。 The wooden crosspiece 72 is joined to the pillar 12 using screws 76. The screw 74 is inserted into the wooden frame 72 and protrudes toward the outdoor side of the column 12, and the screw 74 penetrates the outer heat insulating material 30.

この例においては、外側断熱材３０を、柱１２の屋外側の一方の面を被覆する断熱材３０Ａと、他方の面を被覆する断熱材３０Ｂとに分割して、それぞれの断熱材３０Ａ及び３０Ｂを、ビス７４を用いて木桟７２に固定している。 In this example, the outer heat insulating material 30 is divided into a heat insulating material 30A covering one surface of the column 12 on the outdoor side and a heat insulating material 30B covering the other surface, and each of the heat insulating materials 30A and 30B is fixed to the wooden frame 72 using screws 74.

図６（Ａ）に示すように木桟７２は、上下方向に沿う長尺部材である。複数のビス７４によって断熱材３０Ｂ（又は３０Ａ）が固定された木桟７２は、図６（Ｂ）に示すように、複数のビス７６を用いて柱１２に固定される。 As shown in FIG. 6(A), the wooden crosspiece 72 is a long member extending in the vertical direction. The wooden crosspiece 72 to which the heat insulating material 30B (or 30A) is fixed with a plurality of screws 74 is fixed to the pillar 12 using a plurality of screws 76, as shown in FIG. 6(B).

このように、第１変形例に係る断熱構造では、固定部材７０が、柱１２に接合された木下地材としての木桟７２と、木桟７２に挿入され、柱１２の屋外側へ突出した複数の棒状部材としてのビス７４と、を備えている。 In this way, in the heat insulation structure according to the first modification, the fixing member 70 is inserted into the wooden frame 72 as a base material joined to the column 12 and the wooden frame 72, and protrudes toward the outdoor side of the column 12. It includes screws 74 as a plurality of rod-shaped members.

このビス７４は、外側断熱材３０を貫通している。このようなビス７４によって外側断熱材３０を支持すると、外側断熱材３０の荷重が、ビス７４に作用する。ビス７４の剛性が十分に高ければ、外側断熱材３０に厚みや重量がある場合でも、外側断熱材３０が自重によってずり変形することが抑制される。換言すると、ビス７４としては、外側断熱材３０が自重によってずり変形することを抑制できる程度の剛性を備えたものが選定されている。このため、断熱性を保持し易い。 This screw 74 penetrates the outer heat insulating material 30. When the outer heat insulating material 30 is supported by such a screw 74, the load of the outer heat insulating material 30 acts on the screw 74. If the rigidity of the screws 74 is sufficiently high, even if the outer heat insulating material 30 is thick or heavy, the outer heat insulating material 30 is prevented from shearing and deforming due to its own weight. In other words, the screws 74 are selected to have enough rigidity to prevent the outer heat insulating material 30 from shearing and deforming due to its own weight. Therefore, it is easy to maintain heat insulation properties.

また、このビス７４は、木桟７２に挿入されている。木製の下地材は鋼製の下地材と比較して柔らかいため、ビス、釘、ステープルなど各種の棒状部材を挿入して固定し易い。このためビス７４に代えて、様々な種類の棒状部材を用いることができ、汎用性が高い。 Further, this screw 74 is inserted into the wooden crosspiece 72. Wooden base material is softer than steel base material, so it is easier to insert and fix various rod-shaped members such as screws, nails, and staples. Therefore, various types of rod-shaped members can be used in place of the screws 74, providing high versatility.

（第２変形例）
本開示においては、図７に示すような固定部材８０を用いてもよい。固定部材８０は、ニードル８２及び座金８４を備えている。ニードル８２は、柱１２に接合され、柱１２の屋外側へ突出した複数の棒状部材であり、外側断熱材３０を貫通している。 (Second modification)
In the present disclosure, a fixing member 80 as shown in FIG. 7 may be used. The fixing member 80 includes a needle 82 and a washer 84. The needles 82 are a plurality of rod-shaped members that are joined to the pillars 12 and protrude toward the outdoor side of the pillars 12, and penetrate the outer heat insulating material 30.

図８（Ａ）に示すように、ニードル８２は、外側断熱材３０の固定に先立って、板状の基端部が予め接着剤や両面テープなどを用いて柱１２に接合されている。ニードル８２の先端は、図８（Ｂ）に示すように、上下方向に折り曲げて二股に分かれるように形成されている。外側断熱材３０をニードル８２の先端に押し付けて貫通させたあと、外側断熱材３０の側に座金８４を配置して、ニードル８２の先端を開く。これにより、外側断熱材３０が、柱１２に固定される。 As shown in FIG. 8(A), the plate-shaped base end of the needle 82 is previously joined to the pillar 12 using adhesive, double-sided tape, or the like before the outer heat insulating material 30 is fixed. As shown in FIG. 8(B), the tip of the needle 82 is formed so as to be bent in the vertical direction and bifurcated into two. After the outer heat insulating material 30 is pressed against the tip of the needle 82 and penetrated, the washer 84 is placed on the side of the outer heat insulating material 30 to open the tip of the needle 82. Thereby, the outer heat insulating material 30 is fixed to the pillar 12.

このように、ニードル８２は、外側断熱材３０を貫通している。このようなニードル８２によって外側断熱材３０を支持すると、外側断熱材３０の荷重が、ニードル８２に作用する。ニードル８２の剛性が十分に高ければ、外側断熱材３０に厚みや重量がある場合でも、外側断熱材３０が自重によってずり変形することが抑制される。換言すると、ニードル８２としては、外側断熱材３０が自重によってずり変形することを抑制できる程度の剛性を備えたものが選定されている。このため、断熱性を保持し易い。 The needle 82 thus penetrates the outer insulation 30. When the outer heat insulating material 30 is supported by such a needle 82, the load of the outer heat insulating material 30 acts on the needle 82. If the rigidity of the needle 82 is sufficiently high, even if the outer heat insulating material 30 is thick or heavy, the outer heat insulating material 30 is prevented from shearing and deforming due to its own weight. In other words, the needle 82 is selected to have enough rigidity to prevent the outer heat insulating material 30 from shearing and deforming due to its own weight. Therefore, it is easy to maintain heat insulation properties.

本開示においては、図９に示すような固定部材９０を用いてもよい。固定部材９０は、柱１２に接合され、柱１２の屋外側へ突出した複数の棒状部材であり、外側断熱材３０を貫通している。固定部材９０としては、溶接ピンが用いられる。この溶接ピンは、針部９２と頭部９４とを備えている。針部９２は針状の部材であり、頭部９４は、針部９２の先端に形成された平板状の部材である。 (Third modification)
In the present disclosure, a fixing member 90 as shown in FIG. 9 may be used. The fixing members 90 are a plurality of rod-shaped members that are joined to the pillars 12 and protrude toward the outdoor side of the pillars 12, and penetrate the outer heat insulating material 30. As the fixing member 90, a weld pin is used. This welding pin includes a needle portion 92 and a head portion 94. The needle part 92 is a needle-like member, and the head 94 is a flat member formed at the tip of the needle part 92.

図１０（Ａ）に示すように、固定部材９０は、外側断熱材３０を柱１２に押し当てた状態で、針部９２を外側断熱材３０に突き刺して配置する。針部９２の先端が柱１２に接触した状態で、外側断熱材３０の外側から、頭部９４に電流を流すことより、針部９２の先端が柱１２に溶接される。これにより、外側断熱材３０が、柱１２に固定される。 As shown in FIG. 10(A), the fixing member 90 is placed by piercing the needle portion 92 into the outer heat insulating material 30 with the outer heat insulating material 30 pressed against the pillar 12. With the tip of the needle 92 in contact with the column 12, current is passed through the head 94 from outside the outer heat insulating material 30, thereby welding the tip of the needle 92 to the column 12. Thereby, the outer heat insulating material 30 is fixed to the pillar 12.

このように、固定部材９０は、外側断熱材３０を貫通している。このような固定部材９０によって外側断熱材３０を支持すると、外側断熱材３０の荷重が、固定部材９０に作用する。固定部材９０の剛性が十分に高ければ、外側断熱材３０に厚みや重量がある場合でも、外側断熱材３０が自重によってずり変形することが抑制される。換言すると、固定部材９０としては、外側断熱材３０が自重によってずり変形することを抑制できる程度の剛性を備えたものが選定されている。このため、断熱性を保持し易い。 In this way, the fixing member 90 penetrates the outer heat insulating material 30. When the outer heat insulating material 30 is supported by such a fixing member 90, the load of the outer heat insulating material 30 acts on the fixing member 90. If the rigidity of the fixing member 90 is sufficiently high, even if the outer heat insulating material 30 is thick or heavy, the outer heat insulating material 30 is prevented from shearing and deforming due to its own weight. In other words, the fixing member 90 is selected to have enough rigidity to prevent the outer heat insulating material 30 from shearing and deforming due to its own weight. Therefore, it is easy to maintain heat insulation properties.
