Description

本発明は、建物の断熱構造に関する。 The present invention relates to a building insulation structure.

従来、コンクリート建物の屋根の屋上における断熱構造として、建物の屋上のコンクリート下地に設けられた防水層の上に、長方形板状の断熱材を隙間なく敷き詰め、それらを押さえ具とアンカーボルトによって固定するものが提案されていた（例えば、特許文献１参照）。そして、その敷き詰められた断熱材の上には、防水加工が施されたり、保護材が敷かれたりする。 Conventionally, as a heat insulating structure on the roof of a concrete building, a rectangular plate-shaped heat insulating material is spread without gaps on a waterproof layer provided on the concrete base of the roof of the building, and these are fixed by holding tools and anchor bolts. The one has been proposed (see, for example, Patent Document 1). Then, waterproofing or a protective material is laid on the heat insulating material that has been spread.

実公平０６―９１７９号公報Real Fairness 06-9179 Gazette

一方、防水層、防水加工、保護材は、経年劣化によりひび割れ等が生じる。防水層、防水加工、保護材により断熱材に水分が入り込まないようにしても、経年劣化によるひび割れの隙間から断熱材に多量の水分が入り込んでしまうことは避けられない。しかしながら、上記断熱構造では、コンクリート建物の屋上に断熱材が隙間なく敷き詰められている。また、上記断熱構造では、断熱材の上下面側にも、防水層、保護材が隙間無く配置されたり、防水加工が施されたりしている。このため、上記従来の断熱構造において断熱材には、含有する水分の逃げ場がない。結果、上記断熱構造における断熱材は、多量の水分を継続して含有するため、断熱性能が著しく低下する。 On the other hand, the waterproof layer, the waterproof process, and the protective material are cracked or the like due to deterioration over time. Even if the waterproof layer, waterproofing, and protective material prevent moisture from entering the heat insulating material, it is inevitable that a large amount of water will enter the heat insulating material through the cracked gaps due to aging. However, in the above-mentioned heat insulating structure, the heat insulating material is spread without gaps on the roof of the concrete building. Further, in the above-mentioned heat insulating structure, a waterproof layer and a protective material are arranged without gaps on the upper and lower surfaces of the heat insulating material, and waterproof processing is applied. Therefore, in the above-mentioned conventional heat insulating structure, the heat insulating material does not have a place for moisture contained in the heat insulating material to escape. As a result, the heat insulating material in the heat insulating structure continuously contains a large amount of water, so that the heat insulating performance is significantly deteriorated.

本発明は、斯かる実情に鑑み、断熱材に含まれる水分を低減させ、断熱材の断熱性能を低下させずに維持する断熱構造を提供しようとするものである。 In view of such circumstances, the present invention aims to provide a heat insulating structure that reduces the water content contained in the heat insulating material and maintains the heat insulating performance of the heat insulating material without deteriorating.

以下、本発明の実施の形態について添付図面を参照して説明する。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

まず、図１を参照して本発明の実施の形態における断熱構造１について説明する。断熱構造１は、建物に設けられるものであり、複数の断熱材２と、断熱材固定機構３とを備える。 First, the heat insulating structure 1 in the embodiment of the present invention will be described with reference to FIG. The heat insulating structure 1 is provided in a building, and includes a plurality of heat insulating materials 2 and a heat insulating material fixing mechanism 3.

＜断熱材＞
図１および図２を参照して、断熱材２について説明する。断熱材２は、図１に示すように、例えば、直方体形状に形成されたものが一例として挙げられるが、その他の形状に形成されたものであってもよい。以下において、断熱材２は、直方体形状に形成されたものとして説明する。 <Insulation material>
The heat insulating material 2 will be described with reference to FIGS. 1 and 2. As shown in FIG. 1, the heat insulating material 2 is, for example, one formed in a rectangular cuboid shape as an example, but may be formed in another shape. Hereinafter, the heat insulating material 2 will be described as being formed in a rectangular cuboid shape.

断熱材２は、図１に示すように、建物における断熱材２が設置される予定の面である断熱材設置面４に配置される。断熱材２は、所望の厚みになるように、複数枚が積層されて断熱材設置面４に配置される態様であってもよいし、所望の厚みを有するものが１枚配置される態様であってもよい。図１において左側では、２枚の断熱材２Ｃ，２Ｄが積層されている。図１において右側では、積層された２枚の断熱材２Ｃ，２Ｄと略同じ厚みを有する１枚の断熱材２Ｅが配置されている。 As shown in FIG. 1, the heat insulating material 2 is arranged on the heat insulating material installation surface 4 which is the surface on which the heat insulating material 2 is planned to be installed in the building. The heat insulating material 2 may be arranged in a manner in which a plurality of sheets are laminated and arranged on the heat insulating material installation surface 4 so as to have a desired thickness, or in a manner in which one piece having a desired thickness is arranged. There may be. On the left side in FIG. 1, two heat insulating materials 2C and 2D are laminated. On the right side in FIG. 1, one heat insulating material 2E having substantially the same thickness as the two laminated heat insulating materials 2C and 2D is arranged.

建物は、図２に示すように、例えば、陸屋根９を有するものが一例として挙げられる。この場合、断熱材設置面４として、例えば、陸屋根９の屋上面が挙げられる。陸屋根９の屋上面として、コンクリート下地面９Ａにより構成されたものが想定されるが、これに限定されるものではない。例えば、図３（Ａ）に示すように、コンクリート下地面９Ａの上に他の部材４０が載置される場合、断熱材設置面４は、コンクリート下地面９Ａではなく、他の部材４０の表面４０Ａ（コンクリート下地面９Ａに接する側とは反対側の面）となる。また、断熱材設置面４は、例えば、建物の内部の壁面、床面、建物の内部のその他の面であってもよい。 As shown in FIG. 2, for example, a building having a flat roof 9 can be mentioned as an example. In this case, as the heat insulating material installation surface 4, for example, the roof surface of the flat roof 9 can be mentioned. As the roof surface of the flat roof 9, it is assumed that the roof surface is composed of the concrete base surface 9A, but the roof surface is not limited to this. For example, as shown in FIG. 3A, when another member 40 is placed on the concrete base surface 9A, the heat insulating material installation surface 4 is not the concrete base surface 9A but the surface of the other member 40. It is 40A (the surface opposite to the side in contact with the concrete base surface 9A). Further, the heat insulating material installation surface 4 may be, for example, a wall surface inside the building, a floor surface, or another surface inside the building.

他の部材４０として、図３（Ｂ），（Ｃ）に示すように、例えば、平面状の部材４８の少なくとも一方の平面４４に複数の凸部４１を有する凸部材４２が一例として挙げられる。凸部４１は、平面４４から凸となる。また、凸部４１の裏側に、平面４４とは反対側の平面４５を起点として凹む凹部４６が設けられる。凹部４６は、平面４５と同一平面上に設けられる開口４６Ａを通じて外部に開放される。 As another member 40, as shown in FIGS. 3B and 3C, for example, a convex member 42 having a plurality of convex portions 41 on at least one flat surface 44 of the planar member 48 can be mentioned as an example. The convex portion 41 is convex from the plane 44. Further, on the back side of the convex portion 41, a concave portion 46 recessed from the flat surface 45 on the opposite side to the flat surface 44 is provided. The recess 46 is opened to the outside through an opening 46A provided on the same plane as the plane 45.

図３（Ｃ）に示すように、凸部材４２における複数の凸部４１の先端部４１Ａが陸屋根９のコンクリート下地面９Ａに当接するように載置されると、コンクリート下地面９Ａと、凸部材４２の凸部４１側の平面４４とは、凸部材４２の厚み方向において対向する。そして、コンクリート下地面９Ａと平面４４との間に空間４３が形成される。この空間４３が外部と連通されるように構成されれば、コンクリート下地面９Ａから蒸発する水分は、空間４３を通じて、例えば、図３（Ｂ）の矢印方向へ移動して外部に排出される。換言すると、空間４３は、滞留する蒸気を外部へ排出する水分排出通路として機能する。 As shown in FIG. 3C, when the tip portions 41A of the plurality of convex portions 41 of the convex member 42 are placed so as to abut against the concrete base surface 9A of the flat roof 9, the concrete base surface 9A and the convex member are placed. The plane 44 on the convex portion 41 side of the 42 faces the flat surface 44 in the thickness direction of the convex member 42. Then, a space 43 is formed between the concrete base surface 9A and the flat surface 44. If the space 43 is configured to communicate with the outside, the water evaporating from the concrete base surface 9A moves through the space 43, for example, in the direction of the arrow in FIG. 3B, and is discharged to the outside. In other words, the space 43 functions as a moisture discharge passage for discharging the stagnant steam to the outside.

なお、図３（Ｃ）に示す凸部材４２では、平面４５側に（図示しない）防水シート４７を載置してもよい。また、凸部材４２は、図３（Ｄ）に示すように、開口４６Ａを通じて外部に開放された凹部４６に相当するものを有せず、凸部４１の内部に密閉空間４９を有するように構成されてもよい。 In the convex member 42 shown in FIG. 3C, the waterproof sheet 47 (not shown) may be placed on the flat surface 45 side. Further, as shown in FIG. 3D, the convex member 42 does not have a concave portion 46 opened to the outside through the opening 46A, and is configured to have a closed space 49 inside the convex portion 41. May be done.

また、断熱材２の材料として、例えば、繊維系材料または発泡系材料が一例として挙げられるが、これに限定されるものではなく、その他の材料により形成されてもよい。繊維系材料として、例えば、グラスウール、ロックウール、セルローズファイバーが一例として挙げられる。また、発泡系材料として、ウレタンフォーム、フェノールフォーム、ポリスチレンフォームが一例として挙げられる。 Further, as the material of the heat insulating material 2, for example, a fiber-based material or a foam-based material can be mentioned as an example, but the material is not limited to this, and may be formed of other materials. Examples of the fiber-based material include glass wool, rock wool, and cellulose fiber. Further, examples of the foam material include urethane foam, phenol foam, and polystyrene foam.

＜断熱材固定機構＞
図１～図５を参照して、断熱材固定機構３について説明する。断熱材固定機構３は、図１に示すように、断熱材設置面４の面方向（例えば、面方向Ａ）において隣り合う断熱材２の境界に通気空間５が形成された状態で、複数の断熱材２を固定するものである。断熱材固定機構３は、例えば、突出部６と、固定部７と、押圧機構８とを有する。 <Insulation material fixing mechanism>
The heat insulating material fixing mechanism 3 will be described with reference to FIGS. 1 to 5. As shown in FIG. 1, a plurality of heat insulating material fixing mechanisms 3 are provided in a state where ventilation spaces 5 are formed at the boundaries of adjacent heat insulating materials 2 in the surface direction (for example, surface direction A) of the heat insulating material installation surface 4. It fixes the heat insulating material 2. The heat insulating material fixing mechanism 3 has, for example, a protruding portion 6, a fixing portion 7, and a pressing mechanism 8.

＜突出部＞
突出部６は、図１に示すように、断熱材設置面４から突出する。このような突出部６は、図４（Ａ）に示すように、例えば、柱体１０と、基部１１と、を有する。柱体１０は、例えば、棒状に形成される。また、柱体１０は、自身の延在方向において基部１１から遠位側の柱体１０の端部１０Ａの近傍領域に、第一係合部１２を有する。第一係合部１２は、例えば、柱体１０の端部１０Ａの開口１２Ａを通じて外部と連通する柱体１０の内部空間１３Ａを取り囲む柱体１０の内周面に螺設される雌ねじ溝１４Ａにより構成される。なお、第一係合部１２は、その他の構造であってもよい。 <Protruding part>
As shown in FIG. 1, the projecting portion 6 projects from the heat insulating material installation surface 4. As shown in FIG. 4A, such a protruding portion 6 has, for example, a prism 10 and a base 11. The prism 10 is formed in a rod shape, for example. Further, the prism body 10 has a first engaging portion 12 in a region near the end portion 10A of the prism body 10 distal to the base portion 11 in its extending direction. The first engaging portion 12 is formed by, for example, a female thread groove 14A screwed into the inner peripheral surface of the pillar body 10 surrounding the internal space 13A of the pillar body 10 communicating with the outside through the opening 12A of the end portion 10A of the pillar body 10. It is composed. The first engaging portion 12 may have another structure.

また、柱体１０は、自身の延在方向において基部１１から近位側の端部１０Ｂの近傍領域に、基部１１と係合する第二係合部１５を有する。第二係合部１５は、例えば、柱体１０の端部１０Ｂの開口１２Ｂを通じて外部と連通する柱体１０の内部空間１３Ｂを取り囲む柱体１０の内周面に螺設される雌ねじ溝１４Ｂにより構成される。なお、第二係合部１５は、その他の構造であってもよい。 Further, the prism body 10 has a second engaging portion 15 that engages with the base portion 11 in a region near the end portion 10B proximal to the base portion 11 in its extending direction. The second engaging portion 15 is formed by, for example, a female thread groove 14B screwed into the inner peripheral surface of the pillar body 10 surrounding the internal space 13B of the pillar body 10 communicating with the outside through the opening 12B of the end portion 10B of the pillar body 10. It is composed. The second engaging portion 15 may have another structure.

内部空間１３Ａ，１３Ｂは、それぞれ繋がっていても繋がっていなくてもよい。内部空間１３Ａ，１３Ｂが繋がっている場合、柱体１０は、筒状体となる。 The internal spaces 13A and 13B may or may not be connected to each other. When the internal spaces 13A and 13B are connected, the prism 10 becomes a cylindrical body.

基部１１は、図４（Ａ）に示すように、台座１６と、基部側凸部１７と、基部側係合部１８とを有する。台座１６は、例えば、正方形の板状に形成される。基部側凸部１７は、台座１６の一方側の平面部１６Ａから凸となる。基部側係合部１８は、基部側凸部１７の端面１７Ａから立設しており、柱体１０の第二係合部１５と係合する。基部側係合部１８が第二係合部１５と係合すると、柱体１０は、基部側係合部１８および基部側凸部１７により支持される。 As shown in FIG. 4A, the base portion 11 has a pedestal 16, a base side convex portion 17, and a base portion side engaging portion 18. The pedestal 16 is formed, for example, in the shape of a square plate. The base side convex portion 17 is convex from the flat surface portion 16A on one side of the pedestal 16. The base side engaging portion 18 stands upright from the end surface 17A of the base side convex portion 17 and engages with the second engaging portion 15 of the column body 10. When the base side engaging portion 18 engages with the second engaging portion 15, the prism 10 is supported by the base side engaging portion 18 and the base side convex portion 17.

具体的に基部側係合部１８は、図４（Ａ）に示すように、例えば、雌ねじ溝１４Ｂと螺合可能な雄ねじ溝１８Ａが外周面に螺設されると共に、基部側凸部１７よりも径の小さい柱体により構成される。柱体１０を基部側係合部１８に螺合させると、図４（Ｂ）に示すように、柱体１０の基部１１に近位側の端面１０Ｃは、基部側凸部１７の端面１７Ａに当接する。結果、柱体１０は、基部側凸部１７により支持される。 Specifically, as shown in FIG. 4A, for the base side engaging portion 18, for example, a male screw groove 18A that can be screwed with the female screw groove 14B is screwed onto the outer peripheral surface, and the base side convex portion 17 is used. It is composed of pillars with a small diameter. When the prism 10 is screwed into the base side engaging portion 18, as shown in FIG. 4B, the end surface 10C proximal to the base 11 of the column 10 becomes the end surface 17A of the base side convex portion 17. Contact. As a result, the prism 10 is supported by the base side convex portion 17.

なお、柱体１０と、基部１１との係合は、以上のような態様に限定されるものではない。柱体１０と、基部１１との係合は、例えば、図５に示すように、柱体１０の端部１０Ｂ側の外周面に螺設される雄ねじ溝１８Ａと、基部１１の内周面に螺設される雌ねじ溝１４Ｂにより実現されてもよい。 The engagement between the prism 10 and the base 11 is not limited to the above mode. The engagement between the prism 10 and the base 11 is, for example, as shown in FIG. 5, in the male screw groove 18A screwed on the outer peripheral surface of the end 10B side of the prism 10 and the inner peripheral surface of the base 11. It may be realized by the female thread groove 14B to be screwed.

以上において、突出部６における柱体１０と基部１１とは、分離可能に構成されているが、これに限定されるものではなく、分離不可能に一体形成されていてもよい。 In the above, the prism 10 and the base 11 in the protrusion 6 are configured to be separable, but the present invention is not limited to this, and the pillar 10 and the base 11 may be integrally formed inseparably.

＜固定部＞
固定部７は、図４に示すように、断熱材設置面４等に突出部６を固定するものである。具体的に固定部７は、台座１６を断熱材設置面４等に固定する。断熱材設置面４等には、例えば、断熱材設置面４のみならず、断熱材設置面４よりも下の層の面（例えば、コンクリート下地面９Ａ）も含まれる。 <Fixed part>
As shown in FIG. 4, the fixing portion 7 fixes the protruding portion 6 to the heat insulating material installation surface 4 or the like. Specifically, the fixing portion 7 fixes the pedestal 16 to the heat insulating material installation surface 4 or the like. The heat insulating material installation surface 4 and the like include, for example, not only the heat insulating material installation surface 4 but also the surface of the layer below the heat insulating material installation surface 4 (for example, the concrete base surface 9A).

突出部６は、外力が加わっても動かないよう強固に固定されることが好ましい。したがって、図３（Ａ）に示すように、例えば、コンクリート下地面９Ａに他の部材４０が載置される場合、突出部６の台座１６は、他の部材４０の表面４０Ａよりもコンクリート下地面９Ａに固定されることが好ましい。他の部材４０の表面４０Ａに台座１６が固定されるよりもコンクリート下地面９Ａに台座１６が固定される方が、突出部６は建物に対して安定して固定されるからである。この意味において、コンクリート下地面９Ａに対して他の部材４０が外力により容易に動かない場合、突出部６は、他の部材４０の表面４０Ａに固定されてもよい。なお、突出部６の台座１６がコンクリート下地面９Ａに固定される場合、他の部材４０には、突出部６を通す貫通孔が設けられる。 The protrusion 6 is preferably firmly fixed so as not to move even when an external force is applied. Therefore, as shown in FIG. 3A, for example, when another member 40 is placed on the concrete base surface 9A, the pedestal 16 of the protrusion 6 is a concrete base surface more than the surface 40A of the other member 40. It is preferably fixed to 9A. This is because the protrusion 6 is more stably fixed to the building when the pedestal 16 is fixed to the concrete base surface 9A than when the pedestal 16 is fixed to the surface 40A of the other member 40. In this sense, when the other member 40 does not easily move with respect to the concrete base surface 9A due to an external force, the protrusion 6 may be fixed to the surface 40A of the other member 40. When the pedestal 16 of the protrusion 6 is fixed to the concrete base surface 9A, the other member 40 is provided with a through hole through which the protrusion 6 passes.

固定部７は、例えば、接着剤により構成されることが好ましい。突出部６を断熱材設置面４等に固定するときに、固定工事に伴う騒音が生じないからである。なお、固定部７は、ネジやその他の固定部材により構成されてもよい。 The fixing portion 7 is preferably composed of, for example, an adhesive. This is because when the protrusion 6 is fixed to the heat insulating material installation surface 4 or the like, noise due to the fixing work is not generated. The fixing portion 7 may be composed of screws or other fixing members.

＜突出部の配列＞
突出部６は、図６に示すように、例えば、断熱材設置面４等（例えば、コンクリート下地面９Ａ）において、建物の縦方向Ｂ（図６の矢印Ｂ方向参照）または建物の横方向Ｃ（図６の矢印Ｃ方向参照）に等ピッチで配置されて、固定部７により固定される。このときにピッチとして、例えば、略５００ｍｍ、または略６００ｍｍが一例として挙げられる。 <Arrangement of protrusions>
As shown in FIG. 6, the protrusion 6 is, for example, on the heat insulating material installation surface 4 or the like (for example, the concrete base surface 9A), in the vertical direction B of the building (see the arrow B direction in FIG. 6) or the lateral direction C of the building. They are arranged at equal pitches (see the arrow C direction in FIG. 6) and are fixed by the fixing portion 7. At this time, as the pitch, for example, about 500 mm or about 600 mm can be mentioned as an example.

突出部６は、図６ではマトリクス状に配置されているが、これに限定されるものではなく、その他の配列であってもよい。また、突出部６は、等ピッチではなく、不等ピッチに配置されてもよい。突出部６の配置は、隣り合う断熱材２の境界に形成される通気空間５の配置に関わってくるものである。したがって、断熱材２が水分を多量に含有しやすい位置において通気空間５が形成されるように様々な配置が想定される。 The protrusions 6 are arranged in a matrix in FIG. 6, but the protrusions 6 are not limited to this, and may be in any other arrangement. Further, the protrusions 6 may be arranged at unequal pitches instead of equal pitches. The arrangement of the protrusions 6 is related to the arrangement of the ventilation space 5 formed at the boundary between the adjacent heat insulating materials 2. Therefore, various arrangements are assumed so that the ventilation space 5 is formed at a position where the heat insulating material 2 tends to contain a large amount of water.

＜押圧機構＞
押圧機構８は、断熱材２を断熱材設置面４側に向かって押圧して断熱材２を固定するものである。押圧機構８は、図１および図３（Ａ）に示すように、例えば、押圧体２０と、押圧体相対移動機構２１とを有する。 <Pressing mechanism>
The pressing mechanism 8 presses the heat insulating material 2 toward the heat insulating material installation surface 4 side to fix the heat insulating material 2. As shown in FIGS. 1 and 3A, the pressing mechanism 8 has, for example, a pressing body 20 and a pressing body relative movement mechanism 21.

押圧体２０は、断熱材設置面４に当接する側と反対側の断熱材２の面２Ａに当接する当接面２１Ａを有する。押圧体２０は、例えば、円盤状またはその他の形状の板材により構成される。 The pressing body 20 has a contact surface 21A that abuts on the surface 2A of the heat insulating material 2 on the side opposite to the side that abuts on the heat insulating material installation surface 4. The pressing body 20 is made of, for example, a disk-shaped or other shaped plate material.

押圧体相対移動機構２１は、突出部６に係合して、突出部６の突出方向Ｔ（図３（Ａ）の矢印Ｔ方向参照）に沿って、断熱材２に当接する押圧体２０が突出部６に接近または離間するように押圧体２０を突出部６に対して相対移動させるものである。押圧体相対移動機構２１は、図３（Ａ）に示すように、例えば、進退部２２と、第一係合部１２と、押圧体接続部２３と、を有する。 In the pressing body relative movement mechanism 21, the pressing body 20 that engages with the projecting portion 6 and abuts on the heat insulating material 2 along the projecting direction T of the projecting portion 6 (see the arrow T direction in FIG. 3A). The pressing body 20 is moved relative to the protrusion 6 so as to approach or separate from the protrusion 6. As shown in FIG. 3A, the pressing body relative moving mechanism 21 has, for example, an advancing / retreating portion 22, a first engaging portion 12, and a pressing body connecting portion 23.

進退部２２は、第一係合部１２に係合しつつ、突出部６の突出方向Ｔに沿って、突出部６に対して相対的に進退可能に構成される。進退部２２として、例えば、第一係合部１２における雌ねじ溝１４Ａに対応する雄ねじ溝２２Ａが周面に螺設された柱体２２Ｂが一例として挙げられる。なお、第一係合部１２は、進退部２２が突出部６の突出方向Ｔに沿って、突出部６に対して相対的に進退可能であれば、どのような係合態様であってもよい。 The advancing / retreating portion 22 is configured to be able to advance / retreat relative to the protruding portion 6 along the protruding direction T of the protruding portion 6 while engaging with the first engaging portion 12. As an example of the advancing / retreating portion 22, a columnar body 22B in which a male screw groove 22A corresponding to the female screw groove 14A in the first engaging portion 12 is screwed on the peripheral surface can be mentioned as an example. The first engaging portion 12 may be engaged in any mode as long as the advancing / retreating portion 22 can advance / retreat relative to the protruding portion 6 along the protruding direction T of the protruding portion 6. good.

押圧体接続部２３は、押圧体２０および進退部２２に繋がり、進退部２２の進退に連動して突出部６の突出方向Ｔに沿って、押圧体２０を突出部６に対して相対移動させる。押圧体接続部２３および進退部２２は、例えば、ネジにより構成される。この場合、押圧体接続部２３はネジの頭部に相当し、進退部２２は外周面に雄ねじ溝が螺設されたネジ部に相当する。また、押圧体２０には、上記ネジを挿通させるネジ孔が中央に設けられる。ネジ孔の径は、ネジの頭部の径よりも小さく、ネジ部の径よりも大きい。このため、ネジをネジ孔に挿通させると、頭部がネジ孔の周囲の押圧体２０の上面に当接する。結果、突出部６（基部１１）側に向かって進むようにネジを送ると、押圧体２０もそれに連動して突出部６（基部１１）側に向かって進む。これにより、押圧体２０は、断熱材２を断熱材設置面４側に向かって押圧して断熱材２を固定する。 The pressing body connecting portion 23 is connected to the pressing body 20 and the advancing / retreating portion 22, and moves the pressing body 20 relative to the projecting portion 6 along the projecting direction T of the projecting portion 6 in conjunction with the advancing / retreating of the advancing / retreating portion 22. .. The pressing body connecting portion 23 and the advancing / retreating portion 22 are composed of, for example, screws. In this case, the pressing body connecting portion 23 corresponds to the head of the screw, and the advancing / retreating portion 22 corresponds to the screw portion in which a male screw groove is threaded on the outer peripheral surface. Further, the pressing body 20 is provided with a screw hole in the center through which the screw is inserted. The diameter of the screw hole is smaller than the diameter of the head of the screw and larger than the diameter of the screw portion. Therefore, when the screw is inserted into the screw hole, the head comes into contact with the upper surface of the pressing body 20 around the screw hole. As a result, when the screw is sent so as to advance toward the protruding portion 6 (base 11) side, the pressing body 20 also advances toward the protruding portion 6 (base 11) side in conjunction with it. As a result, the pressing body 20 presses the heat insulating material 2 toward the heat insulating material installation surface 4 side to fix the heat insulating material 2.

なお、押圧機構８は、断熱材２を断熱材設置面４側に向かって押圧して断熱材２を固定可能であれば、上記以外の態様であってもよく、そのようなものも本発明に含まれる。 The pressing mechanism 8 may have an embodiment other than the above as long as the heat insulating material 2 can be pressed toward the heat insulating material installation surface 4 side to fix the heat insulating material 2, and such a mechanism may be used in the present invention. include.

＜断熱材間の境界の通気空間について＞
図７および図８を参照して、隣り合う断熱材２Ｆ，２Ｇの境界Ｋに形成される通気空間５Ａ～５Ｃについて説明する。隣り合う断熱材２Ｆ，２Ｇは、図７（Ａ），（Ｂ）に示すように、突出部６Ａ，６Ｂを介して隣り合う。換言すると、突出部６Ａ，６Ｂは、断熱材２Ｆ，２Ｇの境界Ｋに位置する。ここで突出部６Ａ，６Ｂがスペーサとして機能して、断熱材２Ｆ，２Ｇの境界Ｋに通気空間５Ａ～５Ｃが形成される。図７（Ｂ），（Ｃ）に示すように、通気空間５Ａ～５Ｃは、断熱材２Ｆ，２Ｇの境界Ｋが延びる境界方向Ｅ（図７（Ｂ）の矢印Ｅ参照）において突出部６Ａ，６Ｂと交互に並ぶように形成される。つまり、通気空間５Ａ～５Ｃおよび突出部６Ａ，６Ｂは、境界方向Ｅに沿って通気空間５Ａ、突出部６Ａ、通気空間５Ｂ、突出部６Ｂ、通気空間５Ｃの順に並ぶ。この配置状態において、通気空間５Ｂは、境界方向Ｅにおいて隣接する突出部６Ａ，６Ｂに挟まれる。また、突出部６Ａ，６Ｂは、境界方向Ｅにおいてそれぞれ通気空間５Ａ，５Ｂ、通気空間５Ｂ，５Ｃによって挟まれる。 <Ventilation space at the boundary between heat insulating materials>
With reference to FIGS. 7 and 8, ventilation spaces 5A to 5C formed at the boundary K between the adjacent heat insulating materials 2F and 2G will be described. Adjacent heat insulating materials 2F and 2G are adjacent to each other via protrusions 6A and 6B as shown in FIGS. 7A and 7B. In other words, the protrusions 6A and 6B are located at the boundary K of the heat insulating materials 2F and 2G. Here, the protrusions 6A and 6B function as spacers, and ventilation spaces 5A to 5C are formed at the boundary K of the heat insulating materials 2F and 2G. As shown in FIGS. 7B and 7C, the ventilation spaces 5A to 5C have protrusions 6A in the boundary direction E (see arrow E in FIG. 7B) where the boundary K of the heat insulating materials 2F and 2G extends. It is formed so as to alternate with 6B. That is, the ventilation spaces 5A to 5C and the protrusions 6A and 6B are arranged in the order of the ventilation space 5A, the protrusion 6A, the ventilation space 5B, the protrusion 6B, and the ventilation space 5C along the boundary direction E. In this arrangement state, the ventilation space 5B is sandwiched between the adjacent protrusions 6A and 6B in the boundary direction E. Further, the protruding portions 6A and 6B are sandwiched by the ventilation spaces 5A and 5B and the ventilation spaces 5B and 5C, respectively, in the boundary direction E.

断熱材２Ｆ，２Ｇは、それぞれ、図７（Ａ），（Ｂ）に示すように、断熱材２Ｆ，２Ｇの境界Ｋにおいて、隣り合う断熱材２Ｆ，２Ｇが並ぶ配列方向Ｄ（図７（Ａ），（Ｂ）の矢印Ｄ参照）で対向する対向面２ＢＦ，２ＢＧを有する。断熱材２Ｆ，２Ｇは、配列方向Ｄにおいて、突出部６Ａの周面１０ＤＡ、および突出部６Ｂの周面１０ＤＢの双方に、対向面２ＢＦ，２ＢＧが当接するように配置されることが好ましい。結果、断熱材２Ｆ，２Ｇは、突出部６Ａ，６Ｂが配列される境界方向Ｅに沿う姿勢で容易に整列させることができる。つまり、断熱材２Ｆ，２Ｇの位置決めが容易になる。なお、突出部６Ａの周面１０ＤＡ、および突出部６Ｂの周面１０ＤＢは、それぞれ突出部６Ａ，６Ｂの突出方向に延びる中心軸の周りの周面を指す。 As shown in FIGS. 7 (A) and 7 (B), the heat insulating materials 2F and 2G have an arrangement direction D (FIG. 7 (A)) in which adjacent heat insulating materials 2F and 2G are arranged at the boundary K of the heat insulating materials 2F and 2G, respectively. ), (See arrow D in (B)), and have facing surfaces 2BF and 2BG facing each other. It is preferable that the heat insulating materials 2F and 2G are arranged so that the facing surfaces 2BF and 2BG abut on both the peripheral surface 10DA of the protruding portion 6A and the peripheral surface 10DB of the protruding portion 6B in the arrangement direction D. As a result, the heat insulating materials 2F and 2G can be easily aligned in a posture along the boundary direction E in which the protrusions 6A and 6B are arranged. That is, the positioning of the heat insulating materials 2F and 2G becomes easy. The peripheral surface 10DA of the protruding portion 6A and the peripheral surface 10DB of the protruding portion 6B refer to the peripheral surfaces around the central axis extending in the protruding direction of the protruding portions 6A and 6B, respectively.

通気空間５Ａは、対向面２ＢＦ，２ＢＧ、および、通気空間５Ａ側の突出部６Ａの周面１０ＤＡＡにより周囲を取り囲まれる。通気空間５Ｂは、対向面２ＢＦ，２ＢＧ、通気空間５Ｂ側の突出部６Ａの周面１０ＤＡＢ、および通気空間５Ｂ側の突出部６Ｂの周面１０ＤＢＢにより周囲を取り囲まれる。通気空間５Ｃは、対向面２ＢＦ，２ＢＧおよび、通気空間５Ｃ側の突出部６Ｂの周面１０ＤＢＣにより周囲を取り囲まれる。 The ventilation space 5A is surrounded by the facing surfaces 2BF and 2BG and the peripheral surface 10DAA of the protrusion 6A on the ventilation space 5A side. The ventilation space 5B is surrounded by the facing surfaces 2BF and 2BG, the peripheral surface 10DAB of the protrusion 6A on the ventilation space 5B side, and the peripheral surface 10DBB of the protrusion 6B on the ventilation space 5B side. The ventilation space 5C is surrounded by the facing surfaces 2BF and 2BG and the peripheral surface 10DBC of the protrusion 6B on the ventilation space 5C side.

また、進退部２２は、図４（Ｂ）に示すように、柱体１０よりも径が小さい。このため、図８に示すように、対向面２ＢＦ，２ＢＧが突出部６Ａの周面１０ＤＡに当接するように断熱材２が配置されても、対向面２ＢＦ，２ＢＧは、進退部２２とは当接しない。仮に、進退部２２を突出部６Ａが延長された部分として、進退部２２および突出部６Ａを１つの突出部分と見做した場合、図７（Ａ）に示すように、対向面２ＢＦ，２ＢＧおよび突出部は、対向面２ＢＦ，２ＢＧおよび突出部分（突出部６Ａ）の周面が当接する当接領域Ｐと、対向面２ＢＦ，２ＢＧおよび突出部分（進退部２２）の周面が当接せずに、両者の間に隙間が形成される隙間領域Ｑを有する。当接領域Ｐと隙間領域Ｑとは、突出方向Ｔ（図７（Ａ）の矢印Ｔ方向参照）に沿って並ぶ。 Further, as shown in FIG. 4B, the advancing / retreating portion 22 has a diameter smaller than that of the prism 10. Therefore, as shown in FIG. 8, even if the heat insulating material 2 is arranged so that the facing surfaces 2BF and 2BG come into contact with the peripheral surface 10DA of the protruding portion 6A, the facing surfaces 2BF and 2BG are in contact with the advancing / retreating portion 22. Do not touch. If the advancing / retreating portion 22 is regarded as a portion where the protruding portion 6A is extended and the advancing / retreating portion 22 and the protruding portion 6A are regarded as one protruding portion, as shown in FIG. 7A, the facing surfaces 2BF, 2BG and In the protruding portion, the contact region P with which the peripheral surfaces of the facing surfaces 2BF, 2BG and the protruding portion (protruding portion 6A) abut, and the peripheral surfaces of the facing surfaces 2BF, 2BG and the protruding portion (advancing / retreating portion 22) do not abut. In addition, it has a gap region Q in which a gap is formed between the two. The contact region P and the gap region Q are aligned along the protrusion direction T (see the arrow T direction in FIG. 7A).

本実施形態における当接領域Ｐでは、対向面２ＢＦ，２ＢＧの双方が突出部分（突出部６）の周面に当接しているが、これに限定されるものではない。当接領域Ｐには、例えば、対向面２ＢＦと突出部分（突出部６）の周面のみが当接している場合、対向面２ＢＧと突出部分（突出部６）の周面のみが当接している場合も含まれる。 In the contact region P in the present embodiment, both the facing surfaces 2BF and 2BG are in contact with the peripheral surface of the protruding portion (protruding portion 6), but the present invention is not limited to this. For example, when only the facing surface 2BF and the peripheral surface of the protruding portion (protruding portion 6) are in contact with the contact region P, only the facing surface 2BG and the peripheral surface of the protruding portion (protruding portion 6) are in contact with each other. It is also included if there is.

また、本実施形態における隙間領域Ｑでは、図８に示すように、対向面２ＢＦ，２ＢＧの双方が突出部分（進退部２２）の周面２２Ｃから所定距離離れ、両者の間には隙間空間５０（図１参照）が形成されているが、これに限定されるものではない。隙間領域Ｑには、対向面２ＢＦのみが突出部分（進退部２２）の周面２２Ｃから所定距離離れている場合、対向面２ＢＧのみが突出部分（進退部２２）の周面２２Ｃから所定距離離れている場合も含まれる。隙間空間５０は、境界方向Ｅにおいて突出部６Ａを介して隣り合う通気空間５Ａ，５Ｂを連通させる連通路として機能する。なお、進退部２２の径を大きくして、進退部２２にも対向面２ＢＦ，２ＢＧを当接させて、隙間空間５０が形成されないようにしてもよい。 Further, in the gap region Q in the present embodiment, as shown in FIG. 8, both the facing surfaces 2BF and 2BG are separated from the peripheral surface 22C of the protruding portion (advancing / retreating portion 22) by a predetermined distance, and the gap space 50 is provided between the two. (See FIG. 1) is formed, but is not limited thereto. In the gap region Q, when only the facing surface 2BF is separated from the peripheral surface 22C of the protruding portion (advancing / retreating portion 22) by a predetermined distance, only the facing surface 2BG is separated from the peripheral surface 22C of the protruding portion (advancing / retreating portion 22) by a predetermined distance. It is also included if it is. The gap space 50 functions as a communication passage for communicating adjacent ventilation spaces 5A and 5B via the protrusion 6A in the boundary direction E. The diameter of the advancing / retreating portion 22 may be increased so that the facing surfaces 2BF and 2BG are brought into contact with the advancing / retreating portion 22 so that the gap space 50 is not formed.

通気空間５Ａ～５Ｃでは、例えば、断熱材２の対向面２ＢＦ，２ＢＧ等を通じて蒸発する蒸気が滞留する。通気空間５Ａ～５Ｃに滞留する蒸気が外部へ排出されるよう蒸気排出構造が別途設けられれば、通気空間５Ａ～５Ｃには気流が発生して滞留する蒸気は外部へ排出され、通気空間５Ａ～５Ｃの湿度は低減される。結果、断熱材２に含有する水分は低減され、含有水分に起因する断熱材２の断熱性能の低下を防止することができる。 In the ventilation spaces 5A to 5C, for example, the vapor evaporating stays through the facing surfaces 2BF, 2BG, etc. of the heat insulating material 2. If a steam discharge structure is separately provided so that the steam staying in the ventilation spaces 5A to 5C is discharged to the outside, an air flow is generated in the ventilation spaces 5A to 5C and the staying steam is discharged to the outside, and the steam staying in the ventilation spaces 5A to 5C is discharged to the outside. Humidity at 5C is reduced. As a result, the water content in the heat insulating material 2 is reduced, and it is possible to prevent the heat insulating performance of the heat insulating material 2 from being deteriorated due to the water content.

なお、突出部６Ａ，６Ｂは、通気空間５Ａ～５Ｃの形成においてスペーサとして機能するスペーサ機能を有すると共に、押圧機構８と共に断熱材２を断熱材設置面４に固定する固定機能を有するものであったが、これに限定されるものではない。例えば、図９（Ａ）に示すように、断熱材固定機構３には、スペーサ機能のみを有する突出部６Ｃが含まれてもよい。また、例えば、図９（Ｂ）に示すように、断熱材固定機構３には、固定機能のみを有する突出部６Ｄ，６Ｅが含まれてもよい。突出部６Ｄ，６Ｅは、それぞれ断熱材２Ｆ，２Ｇに対して孔開け加工を施して設けられた専用の貫通孔に挿入される。貫通孔の径は、突出部６Ｄ，６Ｅに径とほぼ同径である。 The protrusions 6A and 6B have a spacer function that functions as a spacer in the formation of the ventilation spaces 5A to 5C, and also have a fixing function that fixes the heat insulating material 2 to the heat insulating material installation surface 4 together with the pressing mechanism 8. However, it is not limited to this. For example, as shown in FIG. 9A, the heat insulating material fixing mechanism 3 may include a protrusion 6C having only a spacer function. Further, for example, as shown in FIG. 9B, the heat insulating material fixing mechanism 3 may include protrusions 6D and 6E having only a fixing function. The protrusions 6D and 6E are inserted into dedicated through holes provided by drilling holes in the heat insulating materials 2F and 2G, respectively. The diameter of the through hole is substantially the same as the diameter of the protrusions 6D and 6E.

＜蒸気排出構造＞
次に、図１０を参照して、陸屋根９を有する建物の蒸気排出構造について説明する。蒸気排出構造は、図１０（Ａ）に示すように、陸屋根９の屋上面であるコンクリート下地面９Ａ上に設けられる通気層３０により構成される。通気層３０は、建物の外部と連通する外部連通空間３１を内部に有する。 <Steam discharge structure>
Next, with reference to FIG. 10, the steam discharge structure of the building having the flat roof 9 will be described. As shown in FIG. 10A, the steam discharge structure is composed of a ventilation layer 30 provided on the concrete base surface 9A which is the roof surface of the flat roof 9. The ventilation layer 30 has an external communication space 31 inside that communicates with the outside of the building.

通気層３０は、図３（Ｂ）～（Ｄ）に示す凸部材４２がコンクリート下地面９Ａに載置されることにより構成される。そして、外部連通空間３１は、コンクリート下地面９Ａと、凸部材４２の凸部４１側の平面４４との間に形成される空間４３に相当する。 The ventilation layer 30 is configured by placing the convex member 42 shown in FIGS. 3B to 3D on the concrete base surface 9A. The external communication space 31 corresponds to a space 43 formed between the concrete base surface 9A and the flat surface 44 on the convex portion 41 side of the convex member 42.

また、通気層３０の上面３０Ａが断熱材設置面４となり、上面３０Ａに断熱材２Ｆが配置される。そして、通気空間５Ａ～５Ｃが通気層３０より上の層に形成される。さらに、外部連通空間３１と通気空間５Ａ～５Ｃとを連通させる連通路３２が外部連通空間３１と通気空間５Ａ～５Ｃの境界に設けられる。 Further, the upper surface 30A of the ventilation layer 30 serves as the heat insulating material installation surface 4, and the heat insulating material 2F is arranged on the upper surface 30A. Then, the ventilation spaces 5A to 5C are formed in the layer above the ventilation layer 30. Further, a communication passage 32 for communicating the external communication space 31 and the ventilation spaces 5A to 5C is provided at the boundary between the external communication space 31 and the ventilation spaces 5A to 5C.

図１０（Ａ）に示すように、突出部６Ａ,６Ｂにおける基部１１（台座１６）がコンクリート下地面９Ａに固定される場合、突出部６Ａ,６Ｂは、通気層３０を貫通して突出する。このとき、突出部６Ａ,６Ｂにおける基部１１側の周面の近傍領域Ｓには、図１０（Ａ），（Ｂ）に示すように、通気空間５Ａ～５Ｃに対して通気層３０が開放される開放領域が設けられる。その開放領域が連通路３２として構成される。なお、通気層３０が開放される開放領域は、突出部６Ａ,６Ｂにおける基部１１側の周面の近傍領域に限定されるものではなく、例えば、境界方向Ｅにおける通気空間５の途中位置に（図１０（Ａ）の楕円領域Ｎ内の連通路３２Ａ参照）に設けられてもよい。 As shown in FIG. 10A, when the base 11 (pedestal 16) in the protrusions 6A and 6B is fixed to the concrete base surface 9A, the protrusions 6A and 6B protrude through the ventilation layer 30. At this time, as shown in FIGS. 10A and 10B, the ventilation layer 30 is opened to the ventilation spaces 5A to 5C in the vicinity region S of the peripheral surface on the base 11 side in the protrusions 6A and 6B. An open area is provided. The open area is configured as a continuous passage 32. The open region where the ventilation layer 30 is opened is not limited to the region near the peripheral surface on the base 11 side of the protrusions 6A and 6B, and is, for example, at an intermediate position of the ventilation space 5 in the boundary direction E ( It may be provided in the communication passage 32A in the elliptical region N in FIG. 10A).

外部連通空間３１は外部と連通しているため、外部連通空間３１には気流が生じやすい（図１０（Ａ）の外部連通空間３１の太線矢印参照）。また、通気空間５Ａ～５Ｃおよび隙間空間５０は、連通路３２、３２Ａを通じて外部連通空間３１と連通している。このため、通気空間５Ａ～５Ｃおよび隙間空間５０にも気流が生じる（図１０（Ａ）の通気空間５Ａ～５Ｃおよび隙間空間５０の太線矢印参照）。この気流により通気空間５Ａ～５Ｃおよび隙間空間５０に滞留する断熱材２から生じた蒸気が、外部連通空間３１を通じて外部に排出される。結果、断熱材２の水分含有率は低減され、含有水分に起因する断熱材２の断熱性能の低下を防止することができる。 Since the external communication space 31 communicates with the outside, an air flow is likely to occur in the external communication space 31 (see the thick arrow of the external communication space 31 in FIG. 10A). Further, the ventilation spaces 5A to 5C and the gap space 50 communicate with the external communication space 31 through the communication passages 32 and 32A. Therefore, an air flow is also generated in the ventilation spaces 5A to 5C and the gap space 50 (see the thick arrow in the ventilation spaces 5A to 5C and the gap space 50 in FIG. 10A). Due to this air flow, the steam generated from the heat insulating material 2 staying in the ventilation spaces 5A to 5C and the gap space 50 is discharged to the outside through the external communication space 31. As a result, the water content of the heat insulating material 2 is reduced, and it is possible to prevent the heat insulating performance of the heat insulating material 2 from being deteriorated due to the water content.

なお、ファン等により構成される（図示しない）送風部または吸気部を用いて外部連通空間３１に強制的に気流を発生させれば、通気空間５Ａ～５Ｃおよび隙間空間５０に滞留する蒸気をより効果的に外部に排出することができる。そのようなものも本発明に含まれる。 If an air flow is forcibly generated in the external communication space 31 by using a ventilation unit or an intake unit (not shown) composed of a fan or the like, the steam staying in the ventilation spaces 5A to 5C and the gap space 50 can be generated. It can be effectively discharged to the outside. Such things are also included in the present invention.

尚、本発明の断熱構造は、上記した実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。 It should be noted that the heat insulating structure of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
