The invention discloses a large-height-difference long-span stiff-skeleton cladding concrete formwork construction method and apparatus, and belongs to the technical field of concrete formwork construction. The apparatus comprises a bottom operation platform, a top operation platform and a cable hanger. The bottom operation platform is composed of three sets of beret pieces, a bottom platform, a top platform, and a carrying pole beam. The top operation platform is composed of a
main bearing beam, an operation platform, winches, electric travel blocks, power distribution cabinets, lugs, a bottom form, lower web forms, upper web forms, a lifting rod, tie rods, U-shaped bolts, barriers, and pads. The large-height-difference long-span stiff-skeleton cladding concrete formwork construction method and apparatus provide high-speed high-precision mounting of aerial
arch bridge arch ring cladding concrete formworks under strong wind,
operation safety risk is greatly reduced, and the method and apparatus are suitable particularly for the overall lifting, transferring and removing of long-span large-height-difference
arch bridge stiff-skeleton cladding concrete bulky formworks.
