摘要

The road joint comprises two longitudinal rigid sections (1,2) each having a longitudinal slot (3,4) for the insertion of the lip (7,8) of a laterally extendable middle section (9). The rigid sections have rigid lateral extensions (13,14) with slots (15,16) for the passage of frames (17,18) for connecting into a concrete anchoring. A tensioning plate is positioned under the lateral extension and has threads for receiving two screws (21).
