【発明の詳細な説明】 （産業上の利用分野） 本発明は建造物等の構築物を外面から断熱する外断熱
壁の施工方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for constructing an outer heat insulating wall for insulating a structure such as a building from the outside.
（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、乾式工法と湿式工法とがあ
る。このうち、湿式工法は第５図に示したように、構築
物のコンクリート驅体１の表面に接着モルタル２を塊状
にして分散配置し、この上に発泡ポリスチレン、ウレタ
ンフォーム等の樹脂発泡体よりなる断熱材３を押付けて
接着する。この断熱材３の表面に接着を目的とした調整
層４が塗布され、その上に仕上げ層であるセメントモル
タル５を塗布して仕上げを行う。(Prior Art) Conventionally, there are a dry construction method and a wet construction method as a construction method of an outer heat insulating wall for insulating the outside of a structure such as a concrete structure. Of these, as shown in FIG. 5, in the wet method, adhesive mortar 2 is lumped and dispersed on the surface of a concrete rod 1 of a construction, and a resin foam such as expanded polystyrene or urethane foam is formed on this. The heat insulating material 3 is pressed and adhered. An adjustment layer 4 for the purpose of adhesion is applied to the surface of the heat insulating material 3, and a cement mortar 5 which is a finishing layer is applied on the adjustment layer 4 for finishing.
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の熱膨脹係数の差によって
生ずる応力等により、調整層４の接着力が低下し、仕上
げ層であるセメントモルタル５にクラックが入ったり、
剥離し、断熱効率の低下を来してしまう。However, in this method, the adhesive force of the adjusting layer 4 is reduced due to the stress caused by the shrinkage of the cement mortar 5 and the difference in the coefficient of thermal expansion between the heat insulating material 3 and the cement mortar 5, and the cement mortar 5 as the finishing layer is cracked. Or
It peels off, resulting in a decrease in heat insulation efficiency.
そこで、この問題を解決するための改良工法として、
第６図示の方法（特開昭61−45055号）が考えられた。
この方法は調整層４を塗布するまでは上記の方法と同じ
であるが、その後、セメントモルタル５を塗布する前に
表面の各所に例えばグラスメッシュ等の網状体７を具備
したアンカーボルト６を断熱材３を貫通してコンクリー

してセメントモルタル５を塗布し、網状体７を完全にセ
メントモルタル５の内部に埋没させて仕上げ面にする。Therefore, as an improved construction method to solve this problem,
The method shown in FIG. 6 (JP-A-61-45055) was considered.
This method is the same as the above method until the adjustment layer 4 is applied, but thereafter, before applying the cement mortar 5, the anchor bolts 6 having a mesh 7 such as a glass mesh are heat-insulated at various points on the surface. The material 3 is penetrated and driven into the concrete rod 1. Thereafter, the cement mortar 5 is applied so as to raise the reticulated body 7, and the reticulated body 7 is completely embedded in the cement mortar 5 to form a finished surface.
この方法は前記湿式方式に比べて表層剥離等が起こり
難いが、断熱効率の面で更に改善が望まれている。In this method, peeling of the surface layer is less likely to occur than in the wet method, but further improvement in the heat insulating efficiency is desired.
即ち、昭和60年建設省住指発第510号の規定による外
断熱壁工法に係る防火性能試験によると、従来方法では
40分位しか耐火性はもたない。That is, according to the fireproof performance test related to the outer insulation wall construction method under the provisions of the Ministry of Construction, Sumitomo No. 510 in 1985, the conventional method
It has fire resistance only for about 40 minutes.
（発明が解決しようとする課題） 上述の改良された施工方法による断熱壁は、昭和60年
の第510号の規定による防火性能試験の加熱時間30分に
対しては充分に合格する断熱性能があるが、加熱時間60
分はもちこたえる性能に対しては不十分である。(Problems to be solved by the invention) The heat insulation wall obtained by the improved construction method described above has a heat insulation performance that sufficiently passes the heating time of 30 minutes of the fire prevention performance test according to No. 510 of 1985. Yes, but heating time 60
Minutes are not sufficient for the ability to hold up.
本発明は上述の新しい防火性能試験に対しても合格す

又、前述の特開昭61−45055号の改良工法では表面に
セメントモルタル５等を塗込む場合に網状体７を引っ張
って起こしながら塗込まないと、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。Further, in the improved construction method of the above-mentioned JP-A-61-45055, when the cement mortar 5 or the like is applied to the surface, the mesh mortar 5 must be pulled up while being applied so that the cement mortar 5 reaches the back side of the mesh 7. It was difficult to get in, 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。In addition, the above-described painting work causes many net-like bodies 7 one by one, which requires a lot of work and a high cost.
さらに、網状体７はセメントモルタル５の層中に塗込
まれているが、網状であるために強度が大きくとれず、
セメントモルタル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, the reticulated body 7 is coated in the layer of the cement mortar 5, but since it is reticulated, the strength cannot be high, and
There is a problem that the finishing layer peeling phenomenon of the cement mortar 5 is likely to occur.
本発明は上述の課題を解決して、作業手間が少なく、
