The beam part construction movable canopy comprises a rail supporting part, moving guide rails, canopyuprights and canopy trusses; the rail supporting part comprises at least eight joist steels arranged along a vertical direction; the joist steels are distributed and fixed at both opposite sides of acast-in-situ beam along a length direction of the cast-in-situ beam; at least four joist steels are arranged at each side; the tops of the joist steels are all positioned on the same horizontal plane, and the tops of the joist steels are higher than the top surface of a template by 30 to 50cm; the moving guide rails are respectively arranged at both opposite sides of the cast-in-situ beam along the length direction of the cast-in-situ beam, and the moving guide rails are both welded and fixed at the upper ends of the joist steels forming the rail supporting part. Therefore, a problem of serious influence on the construction progress, which is caused by a case that a cast-in-situ beam part structure of a bridge is influenced a lot by rainwater in the construction, is solved. The inventionbelongs to the field of bridge construction.
