[0002]

2. Description of the Related Art An outer wall and / or a roof of an existing building (hereinafter, the roof may be abbreviated to simply an outer wall) may be used.
Not only does the landscape deteriorate due to deterioration due to wind and rain, solar radiation, or contamination by dust and exhaust gas, but also the deterioration may occur not only on the outer wall surface but also on the outer wall frame due to frost damage and thermal expansion.

[0003] At present, a panel,
Various exterior wall refurbishment methods have been proposed which fix panel materials such as siding, stone materials, porcelain plates, and glass plates to repair the exterior walls of a deteriorated building and improve the appearance of the exterior.

[0004] By the way, as a countermeasure against the oil crisis that occurred in 1979, the following buildings have a heat insulating structure. As the heat insulation structure, there are mainly an "inside heat insulation structure" in which heat is provided inside the concrete skeleton of the building, and an "outside heat insulation structure" in which heat is provided outside the concrete skeleton of the building.

[0005] The inner heat insulation structure is a structure that occupies the mainstream in Japan and has the advantage of being easy to construct. On the other hand, the outside of the concrete frame is affected by the temperature change in summer and winter. Since it receives and expands and contracts directly, it deteriorates and cracks the skeleton, causing rain leaks and other factors, which is a major factor in shortening the life of the building itself. In addition, since the internal heat insulation structure cannot utilize the large heat storage property inherent in concrete, it also has problems of low cooling / heating efficiency and dew condensation indoors.

[0006] On the other hand, the external heat insulation structure is a structure that occupies the mainstream in Europe and the United States. In particular, since Sweden and Germany were legislated in the middle of the 1970s, they have been adopted in all newly built buildings since the legislation was enacted. Although the construction is complicated and the cost is higher than that of the inner heat insulating structure, it is an excellent structure that does not have the above-mentioned problem of the inner heat insulating structure.

[0007]

In the case of the external heat insulation structure, there is a problem of a thermal bridge between the exterior material and the building frame. In other words, since a metal fixture such as a screw or an anchor for fixing to the building frame is exposed from the surface of the exterior material, or because the fixture is in contact with the surface of the exterior material, a thermal bridge to the building frame is formed. The problem is that As a technique for preventing a thermal bridge between the fixture and the surface of the exterior material, there is a technique described in Japanese Patent Application Laid-Open No. 10-82145.

[0008] However, this technique is a technique applied to a newly-built building designed to have an external heat insulating structure from the beginning, and is not a technique applicable to renovation of an existing building outer wall.

Accordingly, an object of the present invention is to provide a renovated outer wall structure, a renovated roof structure, and a method for constructing the outer heat insulation structure of a building while improving the appearance of the building and improving the beauty of the building.
