Brief description of the drawings
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is the structural representation of the utility model for the plate device of Bridge High-pier hydraulic climbing;
Sequence number in figure: 1, the external mold of facing upward, 2, overlooking surface external mold, 3, internal mold, 4, climbing frame, 5, pull bar.
detailed description of the invention
Embodiment mono-:
Referring to Fig. 1, in figure, the utility model is for the plate device of Bridge High-pier hydraulic climbing, comprise climbing form system and template hydraulic jacking device, described climbing form system comprises the external mold 1 of facing upward, overlooking surface external mold 2 and both sides external mold (not shown), and internal mold 3, wherein on external mold and overlooking surface external mold, be respectively equipped with climbing frame 4 facing upward, described internal mold is structure as a whole, external mold is Split type structure, between internal mold and external mold, form tubular structure, and between interior external mold, be provided with pull bar 5, described template hydraulic jacking device is exterior sheathing hydraulic jacking device.
Described exterior sheathing hydraulic jacking device (not shown) comprises hydraulic jack and upper and lower Commutating box, and lift rail, and wherein the contained cylinder bottom of hydraulic jack portion installs on the ground, and its tailpiece of the piston rod and exterior sheathing are hinged.
