FIG. 14 shows another example of the conventional structure to be repaired, in which a sealing material E is formed at two places. In this case, the sealing material E formed between the dry wall material B and the retaining edge C is removed, and then the construction is performed in the order shown in FIGS. 2, 3, and 1. Needless to say, the end cover structure according to the present invention is formed at the time of new construction, and it is possible to prevent the convex deformation of the dry wall material B due to aging.

[0019]

As described above, according to the end cover structure according to the present invention, the nail head of the fixture in which the dry wall material is beaten to the brain is not exposed to the exterior surface. The deformation of the end of the dry wall material, in particular, the sandwich plate using a synthetic resin foam as a core material can reliably suppress and fix the convexity, and improve the wind resistance. Since the fixture and the end cover reduce the gap between the dry edge and the cut edge formed by the convexity of the dry wall material, rainwater does not enter the inside of the base. The convexity can be corrected without replacing the dry wall material. The decorative side surface always exhibits elasticity, and no gap is formed between the end cover and the dry wall material, so that the waterproofness and the fit (aesthetics) are good. If formed at the time of new construction, it is possible to reliably prevent a convex deformation due to a change over time. There are features and effects such as.
