A SEALING ELEMENT FOR EXPANSION JOINTS

摘要

A sealing element for expansion joints in a concrete structure (10), comprising an elastomeric profile (20) consisting of two longitudinal lateral flanges (21) to be glued onto the end edges of the expansion joint (11), and a central portion (22), to be fitted inside a seat (12), which is recessed in relation to said end edges of the expansion joint (11) and shaped in order to support the hydrostatic pressures upstream the concrete structure (10); and a flexible duct (30), which is installed inside the seat (12) and provided with radial bores (31) opened to the inside of the latter, in order to allow the selective feeding of pre-catalyzed polymeric resin to the inside of the seat (12), after the elastomeric profile (20) has been mounted and affixed to the concrete structure (10).
