The invention discloses a double-curved-surface variable-cross-section fish-bellied box girder steel formwork dismantling construction device and method. The double-curved-surface variable-cross-section fish-bellied box girder steel formwork dismantling construction device comprises a bottom formwork of a double-curved-surface variable-cross-section fish-bellied box girder steel formwork, a traction device and a vibration device, wherein the traction device comprises a winch and a first steel wire rope, the winch is connected with the first steel wire rope, and the first steel wire rope is connected with a to-be-dismantled bottom formwork; and the vibration device comprises a vibrator, and the upper end of the vibrator is arranged at the lower end of the bottom formwork to vibrate, so thatthe bottom formwork is demolded. According to the method, the steel formworks are disassembled in groups, the disassembling speed is high, the surfaces of the box girders can be ensured not to be damaged after being disassembled, the variable-cross-section line type can be effectively guaranteed, and the technical problem of disassembling construction of the double-curved-surface fish-bellied variable-cross-section box girder steel formworks of the landscape bridge on the construction site is well solved.
Description
technical field [0001] The invention relates to the technical field of box girder steel formwork dismantling, in particular to a construction device and method for dismantling a hyperboloid variable-section fish-belly type box girder steel formwork. Background technique [0002] In recent years, with the rapid development of the construction industry, urban bridges have higher and higher requirements for landscape, and fish-belly box girder bridges are mostly designed. The web-type continuous box girder is mostly of equal section. In the construction of the box girder, the assembly of the steel formwork is relatively regular and widely used. However, the shape and structure of the fish-belt steel box girder with a curved section are complex, which makes the removal of the steel formwork difficult. A new challenge has come. Due to the gravity and the extrusion of each assembly block, the steel formwork of the fish-belly continuous box girder with curved and variable cross-se...
