The present invention relates to a floor drainage device for on-slab plumbing. The floor drainage device comprises: a body having a regular polygonal barrel shape having multiple side walls; and connection pipe units integrated with each other and extended in the different directions from each other from the outer surface of each side wall to connect drain pipes. The connection pipe units are manufactured in a shielded state by connection pipe-shielding wall units of the side walls, and selected to connect drain pipes in accordance with the number and installation positions of sanitary ware units used in a bathroom or a toilet. Accordingly, the floor drainage device is provided to have versatility corresponding to the change of the number and installation directions of the sanitary ware units by connecting drain pipes to make the drain pipes communicate with each other, wherein the drain pipes are connected by boring, or separating and removing connection pipe shielding walls of the connection pipes which are manufactured in a shielded state by the connection pipe shielding wall units of the side walls and selected to connect the drain pipes based on the number and installation positions of the sanitary ware units used in a bathroom or a toilet. The body having a regular hexagonal barrel shape is provide to have the connection pipes extended in eight directions from eight sidewalls in order for the sanitary units to be universally used regardless of change in the number and installation direction of the sanitary units, thereby enabling a manufacturer of a floor drain device to reduce the burden of inventory and maintenance costs while allowing a consumer to select a product corresponding to conditions in use and conveniently use the product. |
