Segmented self-traveling type cast-in-place beam hydraulic inner mould and mould erecting and demoulding method thereof

Abstract

The invention discloses a segmented self-traveling type cast-in-place beam hydraulic inner mould and a mould erecting and demoulding method thereof. A mould moving device (2) is composed of a mould moving trolley (22), a guide column device (21), lateral oil cylinders (231), an ejecting oil cylinder (232), a hydraulic system (23) and an electrical system (24). The mould moving device (2) is movably connected with segmented formworks (1) through the guide column device (21). The mould moving trolley (22) is arranged on rails (3), and a formwork set is divided into the segmented formworks (1) in the beam length direction. Each segmented formwork (1) is composed of a top plate (11), upper movable formworks (12) and lower movable formworks (13), wherein the left end and the right end of the top plate (11) are symmetrically provided with the upper movable formworks (12) in a hinged mode, and the other ends of the upper movable formworks (12) are hinged to one ends of the lower movable formworks (13). The lateral oil cylinders (231) are connected between the upper movable formworks (12) and the mould moving device (2). Chain hoists (14) can be connected between the upper movable formworks (12) and the lower movable formworks (13). The ejecting oil cylinder (232) is installed between the guide column device (21) and the mould moving trolley (22). The mould is safe, efficient, good in overall stability and good in economic efficiency.

Description

technical field [0001] The invention relates to a cast-in-place beam inner mold, in particular to a segmented self-propelled cast-in-place beam hydraulic inner mold. The invention also relates to a vertical mold demoulding method of the segmental self-propelled cast-in-place beam hydraulic inner mold. Background technique [0002] At present, the internal formwork of cast-in-place box girders mostly adopts small formwork assembly structures, which are composed of formwork and formwork support systems that form the inner cavity of the box girder. The installation and dismantling are all realized manually, the efficiency is low, the labor intensity is high, the working environment is poor, and the appearance quality of the manufactured box girder is poor. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide a hydraulic internal mold for cast-in-place beams with safety, high efficiency, good overall stability, and...
