Large span composite beam cable-stayed bridge side steel box temporary anchorage system
The invention discloses a large span composite beam cable-stayed bridge side steel box temporary anchorage system and mainly solves the problems that the certain overturning torque is produced due to unbalanced load caused by own load, temporary load or unseating condition, and the certain horizontal or longitudinal push force is produced and applied to a main beam due to two-side asymmetric oblique cable tension force or wind load. Load tables are provided with steel tube concrete columns, first temporary supporting seats supporting side steel boxes temporarily are arranged on the steel tube concrete columns, and the unbalanced bending moment caused by own load, cable force or construction load can be resisted during construction; the horizontal force produced during the construction can be resisted through the connection of longitudinal steel baffling blocks connected to the side steel boxes in a bolted manner and rubber blocks of two sides of a cable tower crossbeam; second temporary supporting seats supporting the side steel boxes are arranged on a bridge tower crossbeam, steel tubes are arranged in the side steel boxes vertically, prestressed steel beams penetrate the steel tubes to anchor box girders to the bridge tower crossbeam, and the side steel boxes can be prevented from angular displacement during construction.
