の外側を断熱する工法とがある。従来では断熱材が柔軟
である等の理由により外壁側を施工するのが困難であっ
たため、−般には前者の工法が採用されていたが、近年
においては断熱効果に格段の差異がある点が注目され、
むしろ後者の工法が採用されつつある。(Prior Art) In general, methods for insulating structures such as houses include methods for insulating the inner walls of the structure and methods for insulating the outer walls, more specifically, the outside of the outer walls. In the past, the former method was generally adopted because it was difficult to install it on the exterior wall side due to the flexibility of the insulation material, but in recent years there has been a significant difference in insulation effectiveness. attracted attention,
Rather, the latter method is increasingly being adopted.
そして、後者の工法によって屋根材の下側すなわち屋根

柱状体１０・・・を設けると共に、各柱状体１０．１０
間に断熱材１１を組込み、更にその外側にコンクリート
パネル１２を組込んだ構成からなる構造体がある。In the latter construction method, as a structure constituting the lower side of the roof material, that is, the roof base, conventionally, as shown in FIG. 8, a plurality of columnar bodies 10 are provided outside the foundation 1b made of concrete or the like. together with each columnar body 10.10
There is a structure in which a heat insulating material 11 is installed in between, and a concrete panel 12 is further installed on the outside thereof.
（発明が解決しようとする問題点）
しかしながら、このような構造体には次のような問題点
があった。(Problems to be Solved by the Invention) However, such a structure has the following problems.

。(a) That is, the foundation 1b, which is a component of the structure,
Column body 10, heat insulating material 11, and concrete panel 12
are made entirely of materials with no nail-retaining strength, so although the roof base structure and the roofing material are temporarily connected by driving nails, there is a possibility that the nails may be carelessly inserted after the nails are driven. There was a problem in that there was a risk that the roofing material would come off, and as a result, the roofing material could be inadvertently removed from the roof base.
特に、屋根材側に近い構成部材がコンクリートパネル１
２なるため、釘の打ち込み自体も非常に困難となってい
たのである。In particular, the component near the roof material side is concrete panel 1.
2, which made driving the nail itself extremely difficult.

その結果この空気層が異常高温となり、よって断熱材１

いう問題点があった。(c) Also, as a result of such gaps occurring between each component, the gaps become air retention layers and radiant heat is stored.
As a result, this air layer becomes abnormally high temperature, and therefore the insulation material 1
1, there was a problem in that the heat insulation effect was impaired.
（ニ）しかも、各構成部材が既述のように一体化された
ものでないために、各構成部材すなわち各断熱層にバラ
ツキが生じ均一な断熱効果が得られなかった。(d) Furthermore, since each component is not integrated as described above, each component, ie, each heat insulating layer, varies, making it impossible to obtain a uniform heat insulating effect.
