本発明は壁面の内部断熱構造体と壁面の内部断熱施工方
法、更に詳しくは、家屋等の構築物の内壁面側に設けら
れる構造体と、家屋等の構築物の壁面を内部的に断熱し
て施工するための壁面の内部断熱施工方法に関する。Detailed Description of the Invention (Industrial Application Field) The present invention relates to an internal wall insulation structure and a wall internal insulation construction method, and more specifically, to a structure provided on the inner wall side of a structure such as a house, The present invention relates to a method for internally insulating a wall of a building such as a house to internally insulate the wall.
（従来の技術）
従来、家屋等の構築物の壁面を内部的に断熱する施工方
法としては種々の方法があるが、その中でも、ウレタン
を断熱材として使用する施工方法が近年採用されつつあ
る。(Prior Art) Conventionally, there are various construction methods for internally insulating the walls of structures such as houses, among which construction methods using urethane as a heat insulating material have been increasingly adopted in recent years.
すなわち、ウレタンは液状のものを吹き付けることによ
って壁面等どのような被施工面にも接着、固化して施工
でき、しかもジヨイント用部材を必要としないことや、
任意の厚みに調整して施工することができること等の利
点を有するため、各種建築用の断熱材として採用されて
いる。In other words, urethane can be applied to any surface such as a wall by spraying it in liquid form, solidifying and adhering to it, and it does not require joint members.
Because it has the advantage of being able to be adjusted to any desired thickness, it is used as a heat insulating material for various buildings.
而して、上記の様な施工方法に於いては、壁面の上面に
ウレタンを塗装し、更にその下地層として該ウレタンの
上面にプラスターあるいはセメント等の無機質系塗装材
を塗装して施工されていたのである。Therefore, in the above construction method, urethane is painted on the upper surface of the wall surface, and then an inorganic coating material such as plaster or cement is painted on the upper surface of the urethane as a base layer. It was.
（発明が解決しようとする問題点）
しかしながら、上記の様に下地層としてプラスターを使

層に於いて接合材料にアルミ等の金具を使用する場合に
は、該金具を腐食するおそれが生じ、下地層としては適
するものではなかった。(Problem to be Solved by the Invention) However, when plaster is used as the base layer as described above, the plaster has little shrinkage, so while it has the advantage of being less prone to cracking, it lacks water resistance. Moreover, since the pH is low, when metal fittings such as aluminum are used as a bonding material in the underlayer, there is a risk that the metal fittings will corrode, making it unsuitable as the underlayer.
一方、セメントは、耐水性に優れ且つＰＨが高いため上
記プラスターの如き問題は生じないが、収縮性が大きい
ためクランクが発生し易く、特に強度のないウレタン等
を断熱材に使用した場合には、構造物全体の強度が保証
されず耐久性に欠けるという致命的な問題点を有してい
たのである。On the other hand, cement has excellent water resistance and a high pH, so it does not have the same problems as plaster, but it has high shrinkage and is prone to cracking, especially when using low-strength materials such as urethane for insulation. However, the strength of the entire structure was not guaranteed and it lacked durability, which was a fatal problem.
よって、上記の様に下地層としてプラスターやセメント
等の無機質系塗装材を使用すると、壁面。Therefore, if an inorganic paint material such as plaster or cement is used as the base layer as described above, the wall surface will be damaged.
断熱層、下地層を一体化して形成することができなため
、壁面に於いて十分な断熱効果が得られないという難点
を有していたのである。Since the heat insulating layer and the base layer cannot be integrally formed, the problem is that a sufficient heat insulating effect cannot be obtained on the wall surface.
従って、本発明は上記の如き問題点を解決するために、
上記セメント系の無機質系塗装材を使用する構造体を対

It was invented for structures that use the above cement-based inorganic paint material, and its purpose is to:
The purpose is to provide a structure with excellent durability, water resistance, and corrosion resistance, and to integrate a wall surface, a heat insulating layer, and a base layer, thereby further improving the heat insulating effect of the wall surface.

る。(Function) That is, since the base layer is made of an inorganic coating material mixed with an expanding agent, even if the inorganic coating material attempts to shrink, the contraction is prevented by the expanding agent. Therefore, the occurrence of cracks can be prevented.
その結果、下地層が断熱層に与える影響を極力阻止でき
、壁面、断熱層、下地層を一体化しうることとなる。As a result, the influence of the base layer on the heat insulating layer can be suppressed as much as possible, and the wall surface, the heat insulating layer, and the base layer can be integrated.
