The device gain of the main beam of a movable span bridge unfolding system

摘要

The invention relates to the construction and repair of engineering structures, namely to devices enhance the main beams of the bridge draw span unfolding system. The technical result is achieved due to the fact that the device gain of the main beam of a movable span bridge unfolding system, comprising a tubular sleeve (1), fitted on the axis of rotation, the radial reinforcing ribs (2), that the rear part rigidly connected to the wall of the main beam of a movable span bridge an annular diaphragm (3) which is passed through technological recesses in the lower parts of the radial ribs (2) and rigidly connected to the wall of the main beam of a movable bridge span, radial stiffening ribs (2) one of the ends is rigidly connected with steel bars (4) close fitting to the tubular sleeve (1) and having a conical contact surface on the tubular sleeve (1). 3-yl.
