Mold supporting structure for variable cross-section cast-in-place box girder at section combining horizontal and longitudinal curves, and construction method of the mold supporting structure
The invention relates to a mold supporting structure for a variable cross-section cast-in-place box girder at a section combining horizontal and longitudinal curves. The mold supporting structure mainly comprises an all-round scaffold, adjustable inclined supports, synchronous hydraulic jacks, composite moulds and adjustable supporting bases, wherein the all-round scaffold is formed by the overlapping connection of scaffold sets; the synchronous hydraulic jacks and the adjustable supporting bases are uniformly arranged at the joints of longitudinal supporting beams and transverse supporting beams at the top; the synchronous hydraulic jacks and the adjustable supporting bases are used as an upper part supporting body system, and a bottom mold is mounted on the top surface; the mounting angle of each lateral mold is adjusted through the adjustable inclined supports, and the lateral molds are fixedly connected with the bottom mold and an inner mold; custom-made steel templates are arranged at chamfers and circular-arc parts of the variable cross-section cast-in-place box girder; a core mold of the variable cross-section cast-in-place box girder is supported by an internal scaffold, and is fixed to the lateral molds through opposite-pull screw rods. Through the adoption of the mold supporting structure disclosed by the invention, the three-dimensional control for the moulds of the cast-in-place box girder at the section combining horizontal and longitudinal curves is realized, and besides, the uniform stress for the scaffold during concrete pouring can be guaranteed. The invention further provides a construction method of the mold supporting structure for the variable cross-section cast-in-place box girder at the section combining horizontal and longitudinal curves.
