断熱改修工法に開方る。[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a method for repairing insulation on the outside of a wooden wall, and more specifically, it relates to a method for repairing insulation on the outside of a wooden wall, and more specifically, a method for installing insulation material easily and effectively on the existing outside wall of a wooden building. We developed an external insulation repair method for wooden walls based on the wet method.

か多い。Technical aspects of the invention and its problems In wooden buildings such as wooden houses, if the insulation of the outer walls is insufficient, especially if the mortar outer walls have cracks, or if the paint is peeling. The exterior walls are often renovated. In cold regions, insulation renovation work is often carried out by covering existing external walls with heat insulating material in order to improve their insulation properties.

モルタルダンゴ工法によれば、外観を良好になづことが
でさるという利点がある。Among the various methods for this insulation repair work, one example of the 9-type 1 method is the so-called mortar dango method, which has been widely known from the past. This mortar construction method involves gluing a heat insulating material made of expanded polystyrene or the like onto the existing outer wall using a mortar outer wall gluing, and then finishing the outer surface of the heat insulating material by painting it with resin, mortar, etc. This mortar construction method has the advantage of maintaining a good appearance.

うおそれかめる。However, with this mortar dango construction method, it is necessary to apply the insulation material while maintaining a certain level of mortar dango, so it is time-consuming to apply the insulation material, and the mortar dango has to wait until it hardens. It takes a long time and 1 hour, and it is difficult to apply the next resin mortar, which is a problem in terms of construction losses. This is especially a big problem when constructing a small area. In addition, if there is significant damage to the existing exterior wall, or if the painted surface is peeled off or the exterior surface is dirty, the contact force of mortar dango alone will not be enough to securely fix the insulation material. There is also the problem of not being able to do anything. Furthermore, due to mortar dango, an air layer will be formed between the existing external wall and the insulation (A), and if this air layer is vented to the outside, there is a risk that the insulation performance will be significantly reduced. .
