Abstract
The utility model discloses a split flexural resistance multidirectional deflexion bridge stretching device which comprises a first steel box girder, a second steel box girder and a seam spanning plate. A pavement layer and a fixed comb tooth plate are arranged on the first steel box girder. A movable comb tooth plate is arranged at an end portion of the fixed comb tooth plate. A C-shaped steel seat is arranged on the second steel box girder. One end of the seam spanning plate achieves position fixation through a fixation end installation seat and a fixation elastic supporting seat on an end face of the second steel box girder. A sealing glue strip is used for sealing between the seam spanning plate and the C-shaped seteel seat. An end portion of the movable comb tooth plate is connected with the seam spanning plate through a two-connection rod. The split flexural resistance multidirectional deflexion bridge stretching device has the advantages that when an end portion of a bridge undergoes transverse displacing and vertical rotation, the two-connection rod structure between the movable comb tooth plate and the seam spanning plate can eliminate affection on the movable comb tooth plate by transverse displacing and vertical rotation of the seam spanning plate and the movable comb tooth plate is in the optimal stressed state.
