本発明は、外断熱構造に関する。 The present invention relates to external insulation structure.

住宅などの建物において、外壁からの熱の拡散を防止する目的で設けられる外断熱構造の一例として特許文献１に記載のものが知られている。
この外断熱構造に使用される外断熱材は、外壁と、この外壁に胴縁を介して取り付けられる外装材との間に複数設けられるものであり、軟質断熱材と、この軟質断熱材に設けられ、他の軟質断熱材が圧縮されてなる圧縮部材とを備え、前記軟質断熱材に、前記圧縮部材が固定されることにより、前記軟質断熱材と前記圧縮部材とが一体化されてなるものである。

しかし、上記方法では、前記軟質断熱材と前記圧縮部材との２種類の断熱材を用意する必要があったため、１種類の断熱材を使用する場合に比べコスト高になる傾向があった。
このため、通常の軟質の外断熱材を使用して外壁断熱構造を施工することが望まれる。しかし、通常の軟質の外断熱材を使用する場合、この外断熱材を外壁表面に設けるとともに、この外断熱材の表面に外装材を固定するのは困難であった。すなわち、外断熱材は軟質であり、施工の際に厚さの目安となるものがないので、外断熱材をその厚さをほぼ均一にして外壁表面に設けるのが困難であった。さらに、外断熱材は軟質であるので、その上に直接外装材を固定するのはほぼ不可能であった。 However, in the above method, since it is necessary to prepare two types of heat insulating materials, that is, the soft heat insulating material and the compression member, the cost tends to be higher than when one type of heat insulating material is used.
For this reason, it is desired to construct an outer wall heat insulating structure using a normal soft outer heat insulating material. However, when an ordinary soft outer heat insulating material is used, it is difficult to provide the outer heat insulating material on the surface of the outer wall and to fix the exterior material on the surface of the outer heat insulating material. That is, the outer heat insulating material is soft, and there is no guideline for the thickness at the time of construction. Therefore, it is difficult to provide the outer heat insulating material on the outer wall surface with the thickness substantially uniform. Further, since the outer heat insulating material is soft, it is almost impossible to directly fix the exterior material thereon.

本発明は、外壁の表面に外断熱材を容易かつ正確に設けることができるとともに、外装材を容易に取り付けることができる外断熱構造を提供することを目的とする。 The present invention, it is possible to provide the surface of the outer wall of the outer heat insulating material easily and accurately, and to provide a external insulation structure that can be attached to the outer package easily.
