A corner ridge or a valley where two waterproof base surfaces formed by laying a plurality of flat square slope plates as waterproof base materials and inclined in mutually different directions intersect with each other. The waterproof base part of the section is formed by diagonally dividing the square upper surface of the flat square plate, which has a downwardly sloping slope from one side to the other side facing the same, and the upper surface is formed from one side. To the apex facing the apex, the waterproof base material having a downward slope, and the upper surface having a downward slope toward the opposite side from the apex, a plurality of waterproof base materials, the corner ridge and the valley. It can be easily formed by installing them while combining them according to the shape of the parts.

In addition, the number of types of waterproof base materials is small, and not only can the waterproof base material be formed very efficiently, but it is also possible to use a small number of types of waterproof base materials.
It is possible to easily form a gathering ridge type waterproof base as shown in FIG. 4A or a gathering ridge type waterproof base as shown in FIG.

の施工手間を大幅に省力できる。Further, since the on-site construction can be made completely dry, plastering work and curing at the on-site are unnecessary, and the construction period can be greatly shortened. Furthermore, the waterproof base material in the corner ridge is formed in the shape of a flat triangle whose upper surface forms a downward sloping surface from one side to the apex facing this, and the waterproof base material in the valley portion has one top surface. Since it is formed into a flat triangular shape that forms a downward sloping surface toward one side facing it, the top surface is a flat square that forms a sloping downward surface from one side to the other side facing it. The gradient plate can be easily formed by dividing it into two equal parts. Further, by forming the large ridge portion flat, it is possible to reduce the amount of residual material due to slicing and to significantly reduce the time and labor required for cutting work.
