Apparatus for reinforcing a beam of single clear span bridge

摘要

The present invention provides a beam reinforcing device of a short span bridge that can improve the bearing capacity of the beam of the short span bridge by using the external steel wire and bidirectional tension fixing device.;Beam reinforcement device of the short span bridge according to the present invention, the reinforcing brackets are installed on each side of both ends of the beam of the bridge, and for supporting and protecting the tension member inserted through the through-holes formed on both ends of the beam; A saddle bracket installed at a lower surface of the central portion of the beam and configured to latch the tension member; A tension member installed to form a closed loop over the through holes, reinforcement brackets and saddle brackets at both ends of the beam; And a bidirectional tension fixing device installed at a predetermined portion on the tension member installed to form the closed loop and tensioning the tension member in both directions.;According to the present invention as described above, the tension member is tensioned by using the bidirectional tensioning device to facilitate the continuous re-tensioning operation, and the tension pressure detecting device is installed to facilitate the maintenance and management of the bridge.
