Abstract

This product is a waterproof board that prevents rainwater from entering through entrances and exits of underground passages, buildings, etc. when flooding occurs due to typhoons, heavy rain, etc. The waterproof board main body and auxiliary panel are formed by connecting multiple hollow aluminum alloy panel bodies in the vertical direction. The waterproof board main body is provided with a detachable auxiliary panel on the back side, and a groove for fitting the auxiliary panel on the front side. The waterproof board is manufactured to a width slightly longer than the width of the entrance opening to which it will be installed. When installing this product at an entrance opening, the back side is installed facing the interior of the building and the front side facing the exterior of the building. When storing, the auxiliary panel, which is fixed to the center of the back side of the waterproof board main body, is fitted into the groove in the center of the front side to allow it to stand on its own.
