Description

本発明は耐火構造における断熱材の施工構造及び断熱材の施工方法に関する。 The present invention relates to a heat insulating material construction structure and a heat insulating material construction method in a fireproof structure.

従来、木造軸組工法、木造枠組壁工法等による構造体では、壁板を支持部材に固定し、壁面を形成することが行われている。このような壁面では、壁面の各支持部材間に断熱材が配置されている。断熱材は、一定寸法に設定されたものが使用されるので、断熱材を各支持部材の間に配置する際に断熱材の長さが各支持部材間の長さよりも小さい場合には、別の断熱材から、不足する長さの断熱材を切り出し、断熱材の端部同士を突き合わせて接合することが行われている。 Conventionally, in a structure by a wooden frame construction method, a wooden frame wall construction method, or the like, a wall plate is fixed to a support member to form a wall surface. In such a wall surface, a heat insulating material is arranged between each support member of the wall surface. Since the heat insulating material is set to a certain size, it is different when the length of the heat insulating material is smaller than the length between the support members when the heat insulating material is arranged between the support members. Insulation material of insufficient length is cut out from the heat insulating material of the above, and the ends of the heat insulating material are butted against each other and joined.

図１１は、従来の断熱材の施工構造を模式的に示す左右断面図である。図１２は、従来の断熱材の施工構造を模式的に示す上下断面図である。図１１、１２に示されるように、隣接する断熱材１、１の端部同士は突き合わせて目地テープ等のシール部材６によって固定されている。しかし、断熱材は加熱により収縮する性質があり、火災などにより断熱材が加熱されると、断熱材１のそれぞれが収縮し断熱材１の端部同士の突き合わせ部に隙間が形成される懸念があった。断熱材の接合部に隙間が形成されると、シール部材６も脱落や燃焼、融解してしまい、断熱材の隙間から炎が噴き出すような現象が発生し、耐火性能が低下してしまう。 FIG. 11 is a left-right cross-sectional view schematically showing the construction structure of the conventional heat insulating material. FIG. 12 is a vertical sectional view schematically showing a construction structure of a conventional heat insulating material. As shown in FIGS. 11 and 12, the ends of the adjacent heat insulating materials 1 and 1 are butted against each other and fixed by a sealing member 6 such as a joint tape. However, the heat insulating material has a property of shrinking due to heating, and when the heat insulating material is heated due to a fire or the like, there is a concern that each of the heat insulating materials 1 shrinks and a gap is formed at the abutting portion between the ends of the heat insulating material 1. there were. If a gap is formed at the joint portion of the heat insulating material, the sealing member 6 also falls off, burns, and melts, causing a phenomenon in which a flame is ejected from the gap of the heat insulating material, and the fire resistance performance deteriorates.

特許文献１には、無発泡不燃層と隣接する発泡性不燃層の一部を重ならせて耐火被覆を形成することが開示されている。 Patent Document 1 discloses that a non-foaming non-combustible layer and a part of an adjacent foamable non-combustible layer are overlapped to form a fireproof coating.

しかしながら、特許文献１に記載の技術は、２つの不燃層の一部を重ならせて耐火被覆を形成しているので火災などにより不燃層同士の耐火被膜の収縮により隙間が発生しにくく、耐火性能を維持することができるが、無発泡不燃層と隣接する発泡性不燃層を形成することが必要となり、施工性に劣る。 However, in the technique described in Patent Document 1, since a part of the two non-combustible layers is overlapped to form a fire-resistant coating, a gap is unlikely to occur due to shrinkage of the fire-resistant coatings between the non-combustible layers due to a fire or the like, and the fire resistance Although the performance can be maintained, it is necessary to form a foamable non-combustible layer adjacent to the non-foaming non-combustible layer, which is inferior in workability.

本発明は、上記従来の事情のもとで考え出されたものであり、その目的は、加熱により断熱材が収縮しても、断熱材の接合部に隙間が発生しにくく、優れた耐火性能を維持でき、施工が容易な断熱材の施工構造及び施工方法を提供することにある。 The present invention has been conceived under the above-mentioned conventional circumstances, and an object of the present invention is that even if the heat insulating material shrinks due to heating, gaps are unlikely to occur at the joint portion of the heat insulating material, and excellent fire resistance performance is achieved. It is an object of the present invention to provide a construction structure and a construction method of a heat insulating material which can be maintained and is easy to construct.

本発明の第１の態様は建物の構造体における断熱材の施工構造である。建物の構造体は、第１方向に所定間隔で配置された複数の支持部材と、支持部材と支持部材の間に配置された複数の断熱材を備える。断熱材は、不燃性繊維が充填された袋体、不燃性繊維から形成された板状体及び不燃性繊維から形成されたシート状体からなる群から選ばれる少なくとも一つである。複数の断熱材は、端部同士が第１方向で重なり、押圧されているものである。 The first aspect of the present invention is a construction structure of a heat insulating material in a building structure. The structure of the building includes a plurality of support members arranged at predetermined intervals in the first direction, and a plurality of heat insulating materials arranged between the support members. The heat insulating material is at least one selected from the group consisting of a bag body filled with non-combustible fibers, a plate-like body formed of non-combustible fibers, and a sheet-like body formed of non-combustible fibers. The plurality of heat insulating materials have their ends overlapping each other in the first direction and are pressed against each other.

本発明の第１の態様では、断熱材は、不燃性繊維が充填された袋体、不燃性繊維から形成された板状体及び不燃性繊維から形成されたシート状体からなる群から選ばれる少なくとも一つであるので、押圧等により、形状を変化させることができる。そして、互いに隣接する断熱材は、断熱材の端部同士が重なり、押圧されて形状が変化している。押圧された断熱材は復元力を有しているので、断熱材の接合部の隙間の発生を抑制できる。また、火災などにより断熱材が加熱されて収縮し、接合部に隙間が発生したとしても、押圧された部分は復元力を有しており発生した隙間を埋めるので、接合部に隙間が生じにくい施工構造となり、優れた耐火性能を発揮することができる。 In the first aspect of the present invention, the heat insulating material is selected from the group consisting of a bag body filled with non-combustible fibers, a plate-like body formed of non-combustible fibers, and a sheet-like body formed of non-combustible fibers. Since there is at least one, the shape can be changed by pressing or the like. Then, the ends of the heat insulating materials that are adjacent to each other overlap each other and are pressed to change the shape. Since the pressed heat insulating material has a restoring force, it is possible to suppress the generation of gaps at the joints of the heat insulating materials. In addition, even if the heat insulating material is heated and contracted due to a fire or the like and a gap is generated at the joint, the pressed portion has a restoring force and fills the generated gap, so that a gap is unlikely to occur at the joint. It has a construction structure and can exhibit excellent fire resistance.

本発明の第２の態様として、第１方向と直交する第２方向において、複数の断熱材は、端部同士が第２方向で重なり、押圧されている。この施工構造によれば、第２方向において、隣接する断熱材の端部同士が押圧されて復元力を有しているので、接合部に隙間が発生しにくい施工構造となり、優れた耐火性能を発揮することができる。 As a second aspect of the present invention, in the second direction orthogonal to the first direction, the ends of the plurality of heat insulating materials overlap each other in the second direction and are pressed. According to this construction structure, in the second direction, the ends of the adjacent heat insulating materials are pressed against each other to have a restoring force, so that the construction structure is less likely to cause a gap at the joint and has excellent fire resistance. Can be demonstrated.

本発明の第３の態様として、第１方向及び第１方向と直交する第２方向に配置された複数の断熱材は、端部同士が第１方向及び第２方向で重なり、押圧されている。この施工構造によれば、第１方向及び第２方向において、隣接する断熱材の端部同士が押圧されているので、第１方向及び第２方向の断熱材の接合部に隙間が発生しにくい施工構造となり、優れた耐火性能を発揮することができる。 As a third aspect of the present invention, the plurality of heat insulating materials arranged in the first direction and the second direction orthogonal to the first direction are pressed with their ends overlapping in the first direction and the second direction. .. According to this construction structure, since the ends of the adjacent heat insulating materials are pressed against each other in the first direction and the second direction, gaps are unlikely to occur at the joints of the heat insulating materials in the first direction and the second direction. It has a construction structure and can exhibit excellent fire resistance.

本発明の第４の態様として、複数の断熱材の端部同士が、互いに斜めに傾斜した状態で対向して当接して押圧されている。この施工構造によれば、断熱材の端部が傾斜した状態で対向して当接されるので、重なり部分が形成されやすく端部同士の密着性がより向上する。そして、断熱材の端部同士の重なり部分は押圧されているので、重なり部分は隙間が発生しにくい施工構造となり、優れた耐火性能を発揮することができる。 As a fourth aspect of the present invention, the ends of the plurality of heat insulating materials are pressed against each other in a state of being obliquely inclined to each other and facing each other. According to this construction structure, since the ends of the heat insulating material are brought into contact with each other in an inclined state, overlapping portions are easily formed and the adhesion between the ends is further improved. Since the overlapping portion between the ends of the heat insulating material is pressed, the overlapping portion has a construction structure in which a gap is unlikely to occur, and excellent fire resistance can be exhibited.

本発明の第５の態様として、断熱材の屋外側及び屋内側の少なくとも一方に板材を備える。断熱材は、端部同士が重なり、板材によって押圧されている。この施工構造によれば、断熱材の屋外側及び屋内側の少なくとも一方において、支持部材などに壁材等の板材が施工され、このような板材によって両断熱材の端部同士の重なり押圧されているので、両断熱材の間に隙間が発生しにくい施工構造となり、優れた耐火性能を発揮することができる。また、板材によって断熱材の重なり部分を押圧するので、断熱材のみを押圧する工程や、押圧し固定する工程が必要ないので、施工性を向上させることができる。 As a fifth aspect of the present invention, a plate material is provided on at least one of the outdoor side and the indoor side of the heat insulating material. The ends of the heat insulating material overlap each other and are pressed by the plate material. According to this construction structure, a plate material such as a wall material is installed on a support member or the like on at least one of the outdoor side and the indoor side of the heat insulating material, and the end portions of both heat insulating materials are overlapped and pressed by such a plate material. Therefore, the construction structure is such that a gap is unlikely to occur between the two heat insulating materials, and excellent fire resistance can be exhibited. Further, since the overlapping portion of the heat insulating material is pressed by the plate material, the step of pressing only the heat insulating material and the step of pressing and fixing are not required, so that the workability can be improved.

本発明の第６の態様として、複数の断熱材の端部同士の重なりを押圧することにより形成された接合線の端部は、シール部材によって覆われている。この施工構造によれば、断熱材の端部同士が重なり、押圧されて形成された接合線の端部が、シール部材によって覆われているので、重なり部分により隙間が発生しにくい施工構造となり、より優れた耐火性能を発揮することができる。 As a sixth aspect of the present invention, the end portion of the joint line formed by pressing the overlap between the end portions of the plurality of heat insulating materials is covered with a sealing member. According to this construction structure, the ends of the heat insulating materials overlap each other, and the ends of the joint lines formed by being pressed are covered with the sealing member, so that the construction structure is such that gaps are less likely to occur due to the overlapping portions. It can exhibit better fire resistance performance.

本発明の第７の態様は、建物の構造体における断熱材の施工方法であって、構造体の第１方向に所定間隔で複数の支持部材を配置する工程と、支持部材と支持部材との間に複数の断熱材を配置する工程と、を備えるものである。また、配置される断熱材として、不燃性繊維が充填された袋体、不燃性繊維から形成された板状体及び不燃性繊維から形成されたシート状体からなる群から選ばれる少なくとも一つを使用するものである。そして、複数の断熱材を、端部同士が第１方向で重なるように配置した状態で押圧する。この施工方法によれば、前記した本発明の第１の態様と同様に、断熱材は、不燃性繊維が充填された袋体、不燃性繊維から形成された板状体及び不燃性繊維から形成されたシート状体からなる群から選ばれる少なくとも一つを使用するので、押圧等によって力をかけることにより、断熱材の形状を変化させることができる。そして、断熱材の端部同士が重なるように配置した状態で押圧するので、隙間の発生を抑制できる。また、火災などにより断熱材が加熱されて収縮したとしても、両断熱材の端部同士の重なり部分を押圧しているので、押圧された断熱材の端部は復元力を有しており、断熱材の接合部の隙間の発生を抑制することができ、優れた耐火性能を発揮することができる断熱材の施工構造を提供することができる。 A seventh aspect of the present invention is a method of constructing a heat insulating material in a structure of a building, which comprises a step of arranging a plurality of support members at predetermined intervals in a first direction of the structure, and a support member and the support member. It includes a step of arranging a plurality of heat insulating materials in between. Further, as the heat insulating material to be arranged, at least one selected from the group consisting of a bag body filled with non-combustible fibers, a plate-shaped body formed of non-combustible fibers, and a sheet-shaped body formed of non-combustible fibers is used. It is to be used. Then, the plurality of heat insulating materials are pressed in a state where the ends are arranged so as to overlap each other in the first direction. According to this construction method, as in the first aspect of the present invention described above, the heat insulating material is formed of a bag body filled with non-combustible fibers, a plate-like body formed of non-combustible fibers, and non-combustible fibers. Since at least one selected from the group consisting of the formed sheet-like bodies is used, the shape of the heat insulating material can be changed by applying a force by pressing or the like. Then, since the pressing is performed in a state where the ends of the heat insulating material are arranged so as to overlap each other, the occurrence of a gap can be suppressed. Further, even if the heat insulating material is heated and shrunk due to a fire or the like, since the overlapping portion between the end portions of both heat insulating materials is pressed, the pressed end portion of the heat insulating material has a restoring force. It is possible to provide a construction structure of a heat insulating material which can suppress the occurrence of a gap at a joint portion of the heat insulating material and can exhibit excellent fire resistance performance.

本発明の第８の態様として、支持部材と支持部材との間に複数の断熱材を配置する工程において、第１方向と直交する第２方向に複数の断熱材を、端部同士が第２方向で重なった状態で、押圧して配置する。この施工方法によれば、前記した第２の態様と同様に、断熱材の端部同士が押圧されているので、断熱材の接合部に隙間が発生しにくい施工構造となり、優れた耐火性能を発揮することができる。 As an eighth aspect of the present invention, in the step of arranging a plurality of heat insulating materials between the support members, a plurality of heat insulating materials are provided in a second direction orthogonal to the first direction, and the ends thereof are second to each other. Place it by pressing it while overlapping in the direction. According to this construction method, since the ends of the heat insulating materials are pressed against each other as in the second aspect described above, the construction structure is such that gaps are unlikely to occur at the joints of the heat insulating materials, and excellent fire resistance is achieved. Can be demonstrated.

本発明の第９の態様として、支持部材と支持部材との間に複数の断熱材を配置する工程において、第１方向及び第１方向と直交する第２方向に複数の断熱材を、端部同士が第１方向及び第２方向で重なった状態で、押圧して配置する。この施工方法によれば、前記した第３の態様と同様に、第１方向及び第２方向において、隣接する断熱材の端部同士が重なり、押圧されているので、加熱により断熱材が収縮しても、接合部が押圧されて復元力を有するので、第１方向及び第２方向の断熱材の接合部に隙間が発生しにくい施工構造となり、優れた耐火性能を発揮することができる。 As a ninth aspect of the present invention, in the step of arranging a plurality of heat insulating materials between the support members, a plurality of heat insulating materials are provided at the ends in the first direction and the second direction orthogonal to the first direction. In a state where they overlap each other in the first direction and the second direction, they are pressed and placed. According to this construction method, as in the third aspect described above, in the first direction and the second direction, the ends of the adjacent heat insulating materials overlap and are pressed, so that the heat insulating material shrinks due to heating. However, since the joint portion is pressed and has a restoring force, the construction structure is such that a gap is unlikely to occur in the joint portion of the heat insulating material in the first direction and the second direction, and excellent fire resistance can be exhibited.

本発明の第１０の態様として、複数の断熱材を、端部同士を、互いに斜めに傾斜した状態で対向させつつ当接させ、押圧する。この施工方法によれば、前記した第４の態様と同様に、複数の断熱材の端部同士を、互いに斜めに傾斜した状態で対向させつつ当接させるので、端部同士の密着性が向上し、端部同士の重なり部分を形成しやすくなる。また、断熱材の端部同士の当接部分は押圧されているので、断熱材の接合部に隙間が発生しにくい施工構造となり、優れた耐火性能を発揮することができる。 As a tenth aspect of the present invention, a plurality of heat insulating materials are brought into contact with each other and pressed with their ends facing each other in a state of being inclined at an angle. According to this construction method, as in the fourth aspect described above, the ends of the plurality of heat insulating materials are brought into contact with each other while facing each other in a state of being inclined at an angle, so that the adhesion between the ends is improved. However, it becomes easy to form an overlapping portion between the ends. Further, since the contact portion between the ends of the heat insulating material is pressed, the construction structure is such that a gap is unlikely to occur at the joint portion of the heat insulating material, and excellent fire resistance can be exhibited.

本発明の第１１の態様として、断熱材の屋外側及び屋内側の少なくとも一方に板材を配置し、断熱材を複数の支持部材の間に配置し、複数の断熱材の端部同士の重なりを板材によって押圧する。この施工方法によれば、前記した第５の態様と同様に、断熱材の屋外側及び屋内側の少なくとも一方において、支持部材などに壁材等の板材を施工し、このような板材によって複数の断熱材の端部同士の重なり部分を押圧するので、断熱材の接合部における隙間の発生を抑制でき、優れた耐火性能を発揮することができる。また、断熱材のみを押圧する工程や、押圧し固定する工程が必要ないので施工性を向上させることができる。 As an eleventh aspect of the present invention, a plate material is arranged on at least one of the outdoor side and the indoor side of the heat insulating material, the heat insulating material is arranged between a plurality of support members, and the ends of the plurality of heat insulating materials are overlapped with each other. Press with the plate material. According to this construction method, as in the fifth aspect described above, a plate material such as a wall material is applied to the support member or the like on at least one of the outdoor side and the indoor side of the heat insulating material, and a plurality of plate materials such as the heat insulating material are used. Since the overlapping portion of the end portions of the heat insulating material is pressed, the generation of a gap at the joint portion of the heat insulating material can be suppressed, and excellent fire resistance can be exhibited. Further, since the step of pressing only the heat insulating material and the step of pressing and fixing are not required, the workability can be improved.

本発明の第１２の態様として、複数の断熱材の端部同士が重なりを押圧することによって形成された接合線の端部を、シール部材によって覆う。この施工方法によれば、前記した第６の態様と同様に、断熱材の接合部に隙間が発生しにくい施工構造となり、より優れた耐火性能を発揮することができる。 As a twelfth aspect of the present invention, the end portion of the joint line formed by pressing the overlap between the end portions of the plurality of heat insulating materials is covered with a sealing member. According to this construction method, similarly to the sixth aspect described above, the construction structure is such that gaps are less likely to occur at the joint portion of the heat insulating material, and more excellent fire resistance can be exhibited.

本発明の断熱材の施工構造は、断熱材の接合部に隙間が発生しにくく、優れた耐火性能を発揮できる。 In the construction structure of the heat insulating material of the present invention, gaps are unlikely to occur at the joints of the heat insulating material, and excellent fire resistance can be exhibited.

As shown in FIG. 1, in the first embodiment, the heat insulating material 1 (1a, 1b), the moisture permeable waterproof sheet 2, and the exterior material 3 are arranged in this order from the indoor side to the outdoor side. Further, the support members 4 are arranged at predetermined intervals in the left-right direction. The left-right direction is an example of the "first direction" of the present embodiment. The support member 4 is fixed to a structure (not shown) located on the indoor side. The structure is, for example, a skeleton such as a steel frame structure or a wooden structure. The structure is composed of a plurality of structural members. The structural members include a plurality of pillars (not shown) arranged at predetermined intervals in the left-right direction, as well as auxiliary members such as studs arranged between the pillars. Steel and wooden squares are used as the pillars and studs, and the combined use of these is also preferable.

断熱材１は、屋内空間の保温、屋外側からの熱の流入を防ぐ建材である。断熱材１は、不燃性繊維が充填された袋体、不燃性繊維から形成された板状体及び不燃性繊維から形成されたシート状体からなる群から選ばれる少なくとも一つである。不燃性繊維は、グラスウール繊維、ロックウール繊維等が好ましい。袋体は、ポリエチレン等のフィルム等からなる袋に不燃性繊維が充填されたものや、また、グラスウール繊維等の不織布からなる袋に不燃性繊維が充填されたものであってもよいし、不燃性繊維から形成された板状体及び不燃性繊維から形成されたシート状体等でもよい。 The heat insulating material 1 is a building material that keeps heat in an indoor space and prevents heat from flowing in from the outdoor side. The heat insulating material 1 is at least one selected from the group consisting of a bag body filled with non-combustible fibers, a plate-shaped body formed of non-combustible fibers, and a sheet-shaped body formed of non-combustible fibers. As the nonflammable fiber, glass wool fiber, rock wool fiber and the like are preferable. The bag body may be a bag made of a film such as polyethylene filled with non-combustible fibers, or a bag made of a non-woven fabric such as glass wool fibers filled with non-combustible fibers, or non-combustible. It may be a plate-like body formed of sex fibers, a sheet-like body formed of non-combustible fibers, or the like.

図１に示すように、断熱材１（１ａ、１ｂ）は、左右方向に延在し、互いに隣り合う支持部材４間に配置されている。断熱材１ａの端部９ａは、隣接する断熱材１ｂの端部９ｂに重なり、重なり部分１０が形成されている。実施の形態１では、このような端部の重なり部分１０は、図２に示すように、隣接する断熱材１ａ、１ｂの端部９ａ、９ｂ同士が重なり対向させられつつ当接させられて形成される。そして、図３に示すように、このような重なり部分１０は、押圧されて断熱材１ａ、１ｂの端部９ａ、９ｂのそれぞれが変形して互いに傾斜した状態で密着し接合させられる。図１では、この重なり部分１０は、左右方向に対して傾斜した接合線Ａとして表される。図１において、重なり部分１０の長さである重なり代Ｈは、接合線Ａの一端から他端までの左右方向に対する長さを意味している。この重なり代Ｈが１０ｍｍ以上であると接合部に隙間が発生しにくくなるので好ましく、５０ｍｍ以上であるとより接合部に隙間が発生しにくいのでより好ましい。 As shown in FIG. 1, the heat insulating materials 1 (1a, 1b) extend in the left-right direction and are arranged between the support members 4 adjacent to each other. The end portion 9a of the heat insulating material 1a overlaps the end portion 9b of the adjacent heat insulating material 1b, and the overlapping portion 10 is formed. In the first embodiment, as shown in FIG. 2, such an overlapping portion 10 of the end portions is formed so that the end portions 9a and 9b of the adjacent heat insulating materials 1a and 1b are overlapped with each other and brought into contact with each other while being opposed to each other. Will be done. Then, as shown in FIG. 3, such an overlapping portion 10 is pressed and the end portions 9a and 9b of the heat insulating materials 1a and 1b are deformed and brought into close contact with each other in an inclined state. In FIG. 1, the overlapping portion 10 is represented as a joining line A inclined in the left-right direction. In FIG. 1, the overlapping allowance H, which is the length of the overlapping portion 10, means the length of the joining line A from one end to the other end in the left-right direction. When the overlapping allowance H is 10 mm or more, a gap is less likely to be generated in the joint portion, and when it is 50 mm or more, a gap is less likely to be generated in the joint portion, which is more preferable.

透湿防水シート２の屋外側に外装材取付部材５が支持部材４に固定されている。各外装材取付部材５は、構造体（図示しない）に対し、複数の外装材３を左右方向及び上下方向に隣接するように取り付けるためのものである。外装材取付部材５としては、例えば、釘、ビス、取付具等またはこれらを併用することができる。外装材取付部材５は、左右方向において一列に並び、かつ、そのような列が上下方向において複数列設けられている。 The exterior material mounting member 5 is fixed to the support member 4 on the outdoor side of the moisture permeable waterproof sheet 2. Each exterior material attachment member 5 is for attaching a plurality of exterior materials 3 to a structure (not shown) so as to be adjacent to each other in the left-right direction and the up-down direction. As the exterior material mounting member 5, for example, nails, screws, mounting tools, etc., or these can be used in combination. The exterior material mounting members 5 are arranged in a row in the left-right direction, and a plurality of such rows are provided in the vertical direction.

外装材取付部材５の屋外側には外装材取付部材５によって外装材３が取り付けられている。外装材３は、屋外壁面を構成する建材であり、四辺形状の板材であり、より具体的には、左右方向または上下方向に長い略矩形状の板材である。本実施の形態では、外装材３は、セメントを含む窯業系材料等からなる。なお、外装材３の材質は特に限定されず、例えば、金属材料、木質素材、樹脂系素材等を適宜使用できる。 The exterior material 3 is attached to the outdoor side of the exterior material attachment member 5 by the exterior material attachment member 5. The exterior material 3 is a building material that constitutes an outdoor wall surface, is a quadrilateral plate material, and more specifically, is a substantially rectangular plate material that is long in the left-right direction or the up-down direction. In the present embodiment, the exterior material 3 is made of a ceramic material or the like containing cement. The material of the exterior material 3 is not particularly limited, and for example, a metal material, a wood material, a resin material, or the like can be appropriately used.

支持部材４は、外装材３を外装材取付部材５によって構造体に固定するためのものである。本実施の形態では、支持部材４はＣ型鋼等の鋼製鋼材である。支持部材４は、ネジや釘、溶接等（図示しない）によって、柱材等の構造体に取り付けられている。また、各支持部材４の左右方向の間隔は、外壁材や内壁材等の寸法や建築構造により設計されるが、耐火性能の面から中心線基準で１０００ｍｍ以下に設定されるのが好ましい。 The support member 4 is for fixing the exterior material 3 to the structure by the exterior material mounting member 5. In the present embodiment, the support member 4 is a steel material such as C-shaped steel. The support member 4 is attached to a structure such as a pillar material by screws, nails, welding or the like (not shown). The distance between the support members 4 in the left-right direction is designed according to the dimensions of the outer wall material, the inner wall material, and the building structure, but is preferably set to 1000 mm or less based on the center line from the viewpoint of fire resistance.

本実施の形態では、壁総厚Ｔ、すなわち、屋外側の外装材３の表面から断熱材１の屋内側の表面までの長さは、建物に要求される耐火性能や断熱性能により設計されるが、耐火性能の面から７４ｍｍ以上であるのが好ましく、１１６ｍｍ以上であるのがより好ましい。 In the present embodiment, the total wall thickness T, that is, the length from the surface of the exterior material 3 on the outdoor side to the surface of the heat insulating material 1 on the indoor side is designed according to the fire resistance and heat insulating performance required for the building. However, from the viewpoint of fire resistance, it is preferably 74 mm or more, and more preferably 116 mm or more.

このように、本実施の形態１によれば、所定間隔で配置された複数の支持部材４の屋外側には外装材３が配置された支持部材４の間には複数の断熱材１ａ、１ｂが配置されている。断熱材は不燃性繊維が充填された袋体、不燃性繊維から形成された板状体及び不燃性繊維から形成されたシート状体からなる群から選ばれる少なくとも一つであるので、押圧により変形することができるものである。そして、互いに隣接する断熱材１ａ、１ｂは、断熱材の端部９ａ、９ｂ同士が重なり、押圧されて形状が変化している。押圧された断熱材は復元力を有しているので、断熱材の接合部の隙間の発生を抑制できる。また、火災などにより断熱材１ａ、１ｂが加熱されて収縮し、接合部に隙間が発生したとしても、押圧された部分は復元力を有しており発生した隙間を埋めるので、接合部に隙間が生じにくい施工構造となり、優れた耐火性能を発揮することができる。 As described above, according to the first embodiment, a plurality of heat insulating materials 1a and 1b are provided between the support members 4 in which the exterior material 3 is arranged on the outdoor side of the plurality of support members 4 arranged at predetermined intervals. Is placed. Since the heat insulating material is at least one selected from the group consisting of a bag body filled with non-combustible fibers, a plate-like body formed of non-combustible fibers, and a sheet-like body formed of non-combustible fibers, the heat insulating material is deformed by pressing. Is something that can be done. The heat insulating materials 1a and 1b adjacent to each other have their shapes changed by being pressed by the end portions 9a and 9b of the heat insulating materials overlapping each other. Since the pressed heat insulating material has a restoring force, it is possible to suppress the generation of gaps at the joints of the heat insulating materials. Further, even if the heat insulating materials 1a and 1b are heated and contracted due to a fire or the like and a gap is generated in the joint portion, the pressed portion has a restoring force and fills the generated gap, so that the gap is formed in the joint portion. The construction structure is such that it is less likely to occur, and excellent fire resistance can be exhibited.

また、断熱材１ａ、１ｂの端部９ａ、９ｂが互いに斜めに傾斜した状態で対向して当接し押圧されているので、重なり部分が形成されやすく端部同士の密着性がより向上する。そのため、接合部に隙間が発生しにくく、優れた耐火性能を発揮することができる。 Further, since the ends 9a and 9b of the heat insulating materials 1a and 1b are opposed to each other and pressed against each other in a state of being obliquely inclined to each other, overlapping portions are easily formed and the adhesion between the ends is further improved. Therefore, gaps are less likely to occur at the joints, and excellent fire resistance can be exhibited.

更に、断熱材１ａ、１ｂの端部９ａ、９ｂの重なり部分１０は屋内側から屋外側に向けて押圧するので、屋外側へ突出しようとするが、外壁材３が配置されているので、押圧による突出が抑制された状態で変形して互いに傾斜した状態で密着てしている。互いに密着した断熱材１ａ、１ｂの端部９ａ，９ｂの重なり部分１０は変形しているが、復元力を有した状態を維持しているので、両断熱材の間に隙間が発生しにくい施工構造となり、優れた耐火性能を発揮することができる。 Further, since the overlapping portion 10 of the end portions 9a and 9b of the heat insulating materials 1a and 1b is pressed from the indoor side to the outdoor side, it tries to project to the outdoor side, but since the outer wall material 3 is arranged, it is pressed. It is deformed in a state where the protrusion due to the above is suppressed, and is in close contact with each other in a state of being inclined. Although the overlapping portion 10 of the end portions 9a and 9b of the heat insulating materials 1a and 1b that are in close contact with each other is deformed, the state of having a restoring force is maintained, so that a gap is unlikely to occur between the two heat insulating materials. It has a structure and can exhibit excellent fire resistance.

更に、断熱材取付部材７やシール部材６を併用することで、断熱材１ａ、１ｂの重なり部分１０を押圧に加えて断熱材取付部材７やシール部材６による接合力が加えられるので、隙間の発生をより強固に抑制することができる。また、断熱材の端部同士が重なり、押圧されて形成された接合線の端部が、シール部材６により覆われるので、重なり部分により隙間が発生しにくく、より優れた耐火性能を発揮することができる。 Further, by using the heat insulating material mounting member 7 and the sealing member 6 together, the overlapping portion 10 of the heat insulating materials 1a and 1b is pressed and the bonding force by the heat insulating material mounting member 7 and the sealing member 6 is applied. The occurrence can be suppressed more firmly. Further, since the ends of the heat insulating materials overlap each other and the ends of the joint wire formed by being pressed are covered by the sealing member 6, gaps are less likely to occur due to the overlapping parts, and better fire resistance is exhibited. Can be done.
