A concrete beam and a mounting mechanism, which is a part thereof, is a system with which reinforced concrete beams made into the form of a log structure are quickly, flexibly, and tightly-mounted together, generating waterproof structures to be used, among others, in dam structures, bulkheads, piers, jet-ties, bridges. The beams (17) and (18) are fastened onto each other with a joint device (7).
