本発明は建造物等の構築物の外面から＠熱する外断熱壁
の施工方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for constructing an externally insulated wall that heats a structure such as a building from the outside surface.
（従来の技術）
従来、コンクリート建造物等の構築物の外側を断熱する
外断熱壁の施工方法は、乾式１法と湿式１法とがある。(Prior Art) Conventionally, there are two methods of constructing an external insulation wall for insulating the outside of a structure such as a concrete building: a dry method and a wet method.
このうち、湿式１法は第３図に示したように、構築物の
コンクリート躯体１の表面に接着モルタル２を塊状にし

−１−（以後、両者をまとめてセメントモルタルで代表
させる。）５を塗布して仕上げを行う。Among these methods, the wet method 1, as shown in Fig. 3, consists of distributing adhesive mortar 2 in lumps on the surface of the concrete frame 1 of the structure, and placing heat insulating material 3 such as expanded polystyrene on top of this.
Press and glue. An adjustment layer 4 for the purpose of adhesion is applied to the surface of this heat insulating material 3, and a finishing layer of cement mortar or glass fiber concrete IJ is applied on the surface of the insulation material 3.
-1- (Hereinafter, both will be collectively represented by cement mortar.) 5 is applied and finished.
しかし、この方法ではセメントモルタル５・の収縮や断
熱材３とセメントモルタル５の熱膨張係数の差によって
生ずる応力等により、調整層４の接着力が低下し、仕上

剥離の原因となる。However, with this method, the adhesive force of the adjustment layer 4 decreases due to stress caused by shrinkage of the cement mortar 5 and the difference in thermal expansion coefficients between the heat insulating material 3 and the cement mortar 5, and the cement mortar 5, which is the finishing layer, enters,
This may cause peeling.

０５５号）。Therefore, the method shown in Figure 4 was devised as an improved construction method to solve this problem. This method is the same as the above method until the adjustment layer 4 is applied, but after that, before applying the cement mortar 5, the anchor bolt is equipped with a flexible mesh 7 such as glass mesh at various places on the surface. 6 is driven into the concrete frame 1 through the insulation material 3. After that, apply the cement mortar 5 so that the mesh body 7 is raised up, and completely cover the mesh body 7 with the cement mortar 5.
to create a finished surface (Japanese Unexamined Patent Publication No. 61-45
No. 055).
（発明が解決しようとする問題点）
上述の改良工法では、表面にセメントモルタル５等を塗

いと、網状体７の裏側にまでセメントモルタル５が入り
込み難く、密着性に問題があった。(Problems to be Solved by the Invention) In the above-mentioned improved construction method, when applying cement mortar 5 etc. to the surface, unless the net-like body 7 is pulled and raised while applying it, the cement mortar 5 will reach the back side of the net-like body 7. It was difficult to penetrate, and there was a problem with adhesion.
また、上述のような塗込み作業は数多くの網状体７をい
ちいち引き起こしてゆくために、作業手間が多く、コス
ト高となってしまう。Furthermore, since the above-described coating operation causes a large number of net-like bodies 7 one by one, the operation is labor-intensive and costs are high.
さらに、網状体７はセメントモルタル５の層中に塗込ま

メントモルタル５の仕上げ層剥離現象が起こり易いとい
う問題がある。Further, although the net-like body 7 is coated into the layer of the cement mortar 5, since it is in the form of a net, it cannot have a large strength, and there is a problem that the finish layer of the cement mortar 5 is likely to peel off.

ものである。(Means for solving the problem) In order to achieve the above-mentioned purpose, after attaching the heat insulating material 3 to the outer wall of the concrete frame 1 of the structure,
The anchor bolt 6 is passed through the hole washer 8 from the outside of the heat insulating material 3 to connect the concrete frame 1 of the structure.
After that, cement mortar 5 is applied to the outer surface of the heat insulating material 3 so that the hole washer 8 is buried, and the head 6-1 of the anchor bolt 6 is fitted into the hole washer 8. It comprises a recessed portion 8-2 and a perforated annular disk 8-3 embedded in the cement mortar 5.
