FLOOR DRAIN FOR SYSTEMS FOR EVACUATING PRECIPITATION WATER FROM WATERTIGHT COVERINGS

摘要

The present invention concerns a floor drain for systems for evacuating water from waterproofing coverings precipitation. Said exhaust outlet mainly consists of: - a clamping plate (1) arranged for allowing interposition of said discharge outlet between drainage pipes (G) and clearing pipes (CS) of said system; - a first pipe 2 and a second pipe 3, reciprocally connected in Y- shape and integral with said clamping plate 1; - a tubular joint (4) arranged for connecting the single drainage grids (G) with pipe (2) of the exhaust outlet corresponding to said grids, and consequently with the clearing pipe (CS) connected to the same; - a flat structure (5) arranged for supporting said tubular joint (4); - a double order of dot- like or lamellar spacers (6) arranged for allowing the rest of said flat structure (5) onto said clamping plate (1) determining the realization of a hollow gap (7) between said flat structure (5) and said clamping plate (1).
