BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a construction method for a building outer insulation method, and more particularly, to a construction method in the case where a structural surface material is assembled on the outer surface of a shaft assembly material and a heat insulation material is laid outside the surface material. . Examples of buildings to which this construction method can be applied include buildings of conventional wooden frame construction methods, wooden framework wall construction methods such as two-by-four, and steel framework steel framework wall construction methods.

[Prior art]
In recent years, from the viewpoint of energy saving and residential comfort, it has become widespread to lay a heat insulating material on the floor, wall, ceiling, and roof base of a building. And as a heat insulation method for the wall portion of a detached building, an interaxial heat insulation method and an external heat insulation method are widely known. On the other hand, the next-generation energy-saving standards, which were implemented after several revisions of the energy-saving standards, generally stipulate that the thickness of the insulation is further thicker than the previous standards. There is a need for a heat insulating material that does not fit, and an outer heat insulating method that is less likely to cause dew condensation than an inter-shaft heat insulating method and that can reduce variations in room temperature. For this reason, it is expected that the outer insulation method will become widespread in the future.
[0003]
However, conventionally, the inter-shaft insulation method has been widely used, and the external insulation method has not been used much. As one of the factors, in the heat insulation between shafts, the exterior material can be fixed and fixed easily from the outer surface of the shaft material with a small trunk edge, but in the external insulation method, the heat insulation material jumps out of the shaft. When the thickness of the heat insulating material to be laid becomes thick, it is considered that the fixing of the exterior material becomes difficult. As an example, plate insulation such as resin foam insulation is often used as a conventional outer insulation method, but if the insulation is thin, the fastening strength of the exterior material is sacrificed. A method of laying down the heat insulating material by pressing it with a member that performs a trunk function has been tried in part. However, in this method, since the heat insulating material is not as strong as wood and has a risk of softening or melting at a high temperature, the strength transmission of the member performing the trunk edge function to fasten the exterior material is transmitted to the heat insulating material. However, the fastening strength of the exterior material to the shaft material depends on the bending strength in the state in which the heat insulating material such as the nail which fastens the member performing the trunk edge function to the shaft material has disappeared. In order to obtain the strength, it is necessary to use a thick and long nail or the like. For example, if a heat insulating material having a thickness of 50 mm is used, the thickness of the body edge material is about 20 mm and the total thickness becomes 70 mm. In consideration of the above, the nails that can be used are at least 90 mm, and if you try to use them, there is a risk that the trunk edge will crack and it will not function, and there will be a risk of dents in the insulation. Ri fastening it becomes difficult to the appropriate position, leaving the issue to the fastening fixing of the exterior material. For this reason, this method is not used much. On the other hand, in the next generation energy saving standards, the required thickness differs depending on the performance of the area and the heat insulating material, but the wall portion needs to have a thickness of about 100 mm, and such a thick heat insulating material is required. The use is rarely used because the problem of the fastening strength of the exterior material is too large to be realistic. For this reason, in some cases, heat insulating material with the required thickness of the heat insulating material divided into multiple layers is laminated, and square members corresponding to the trunk edge are assembled vertically and horizontally for each layer and the intersections are fastened with nails etc. Thus, a device for holding and fixing the exterior material is made. However, in this method, since the holding strength of the exterior material etc. depends on the fastening of the cross-shaped crossing of the square material corresponding to the trunk edge, the problem of strength still remains, and the heat insulating material is divided and attached Therefore, there is a problem in that it takes time for construction. Because of this, at present, as mentioned above, there are not enough proposals for appropriate fastening methods, etc., so it is difficult to perform appropriate thermal insulation by the external thermal insulation method. Therefore, the proposal of the construction method of the suitable outer-stretch heat insulation construction method including the fastening method of a heat insulating material is desired.
[0004]
