A variable cross-section self-adaptive climbing formwork system for a tilt tower and a construction method thereof

Abstract

This invention provides an adaptive climbing formwork system for tilting towers with variable cross-sections and its construction method. The system includes a base support, a transfer support capable of swaying left and right on the base support, multiple rotatable polygonal frames on the base support, a climbing mechanism on one side of both the base support and the transfer support, multiple locking mechanisms on the base support, a rear support on the transfer support, and a formwork support on the rear support. The overall structure can traverse concave spaces, allowing the transfer support to sway left and right and adjust its posture relative to the base support. Combined with the transition method of pre-embedded guide rails at the top of the concave space, it can smoothly traverse the concave area, completing the continuous pouring of the concave space. This overcomes the shortcomings of traditional climbing formwork systems, which cannot adapt to concave structures and cannot climb across gaps. It replaces manual high-altitude calibration and repeated hoisting and transportation; it eliminates the need for multiple sets of climbing formwork devices of different specifications to handle irregular cross-sections, reducing equipment investment, manual operation, and machine usage, saving construction costs and avoiding resource waste.
