PROCEDURES FOR THE RECOVERY OF SPANISHED IMPORTERS -PLACE ELEMENTS AND STRENGTHENING INSTRUMENTS

摘要

A prestressed concrete beam (1) is cast with a rectilinear longitudinal profile and a filling piece (13) extending from a surface of the beam (1) to the reinforcing strands (6) is embedded. After hardening of the concrete and removal of the filling piece (13) if necessary, the beam (1) is deflected in a predetermined angle by rotating the beam sections (2, 3) on either side of the recess (4) formed by the filling piece in such a direction that the recess is diminished, following which the beam sections (2, 3) are retained in the predetermined angle. A reinforcement assembly made in two equal halves and connected with a breakable joint may be embedded in the area of the recess to reinforce the beam sections (2, 3).
