Abstract

The invention provides a cable bent tower operation platform formwork separating and lifting system. The cable bent tower operation platform formwork separating and lifting system comprises a formworksystem, a supporting system and a protection system. The formwork system comprises an inner formwork and an outer formwork, and the inner formwork and the outer formwork are fixedly connected throughopposite-pull screws. The supporting system comprises an enclosure, a lifting frame and a supporting rod, the supporting rod is fixedly arranged in the concrete, the lifting frame is fixedly arrangedon the enclosure, the enclosure is arranged on the outer side of the outer mold in a sleeving mode, a center hole jack is arranged on the lifting frame, the center hole jack is in transmission connection to the supporting rod, and the outer mold is hung on the lifting frame; the protection system comprises an operation table and guardrails, the operation table is hung below the enclosure, and theguardrails are fixedly arranged on the periphery of the operation table. The center hole jack climbs upwards along the supporting rod, the whole supporting system can be driven to climb as a whole, the next section of steel bar construction procedure is conducted, and the whole construction process is continuous. Construction is conducted in the form the same as that of a creeping formwork in a formwork assembling mode, the advantages of a sliding and overturning combined integrated process are achieved, and the appearance quality the same as that of a turnover formwork can be achieved whileit is guaranteed that the construction speed is equal to that of the sliding formwork.

Description

technical field [0001] The application relates to the technical field of high tower and pier construction, in particular to a formwork separation and lifting system for a cable tower operation platform. Background technique [0002] At present, with the rapid development of transportation needs and the increasing progress of bridge technology, modern bridges are gradually developing towards long-span directions. Due to structural needs and the constraints of topography and landforms at bridge locations, piers with a height of more than 100 meters in bridge design It is no longer uncommon to use cable towers with a height of hundreds of meters in cable-stayed bridges and suspension bridges, which put forward higher requirements for construction technology. Faced with such a high tower column, how to achieve high-quality, safe and efficient construction is a difficult problem in modern bridge construction. [0003] In the early construction of high piers and high towers, the ...
