を形成した点に特徴がある。Moreover, in the event of a water leak, it would be necessary to destroy the waterproof retaining material, repair the waterproof layer, and then redo brickwork, mortar finishing, etc., making maintenance of the waterproof layer extremely complicated. . In view of this current situation,
The present invention solves the above-mentioned problems by effectively utilizing the characteristics of reinforced cement containing glass fibers, such as good moldability, sufficient strength even when molded into thin walls, and resistance to shrinkage cracks. In the horizontal part of the concrete structure,
The waterproof layer is formed so that its edge rises above the finished surface of the horizontal part along the rising part of the concrete frame, and glass fiber is formed at the corner of the horizontal part and the rising part. A molded plate for waterproofing and finishing, which is formed into an approximately L-shaped longitudinal section by reinforcing cement, has a horizontal plate part that covers the horizontal part of the waterproof layer, and a vertical plate part that is above the finished surface of the horizontal part. The waterproof layer is placed in a state that covers the rising part of the waterproof layer that has risen up to the point where it is tightened and fixed to the rising part with bolts, and the finished surface of the corner part is formed by these horizontal plate parts and vertical plate parts. There are characteristics.

かつ経済的に実施できる。2. The molded plate is molded with reinforced cement containing glass fibers, so even if it is formed into a thin wall, sufficient strength can be secured due to the reinforcing effect of the glass fibers, and shrinkage cracks will not occur, so it is thin as a molded plate. It is lightweight, so it is easy to carry the molded plate to the site and install it, and unlike PC plates reinforced with steel bars, it is easy to cut, so it can be cut on site according to the drainage slope, and the same It can be easily and economically constructed using a shaped plate. 3.Since the molded plates are bolted and fixed to the rising parts of the concrete structure, there is no need to worry about water leaking around the bolts, and when maintaining the waterproof layer, the molded plates can be loosened by loosening the bolts. The molded plate can be removed without destroying it, and after the waterproof layer is repaired, the molded plate can be reused as it is, so maintenance of the waterproof layer can be carried out easily, quickly and economically.
