Beam part construction movable canopy and construction method thereof

The invention provides a beam part construction movable canopy and a construction method thereof. 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 constr
