Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic creeping formwork, in particular to a hydraulic creeping formwork lifting device and a convenient lifting method thereof. BACKGROUND

[0002] Hydraulic creeping formwork is an advanced formwork system for high-rise building, high pier of bridge, cable tower and other high-rise concrete structure construction. The core is to realize the self-climbing of the formwork through hydraulic power, without relying on external lifting equipment such as tower crane. Its basic composition includes formwork system, climbing frame, hydraulic system and safety protection system. When working, it relies on the structure that has been poured to fix, and the whole is driven upward by hydraulic oil cylinder to complete one layer of construction and repeat the cycle, which is suitable for complex structures such as core tube, shear wall and curved surface variable cross section. Compared with the traditional formwork, it has the advantages of efficient construction, high safety and cost saving, and is a common technology for super high-rise and high-rise structure construction.

[0003] The existing hydraulic creeping formwork realizes the self-climbing of the formwork by hydraulic power, and has the advantages of high efficiency and safety in the construction of high-rise buildings and other high-rise concrete structures. However, there is a obvious shortcoming in the fixing of the sliding rail and the base. Before each formwork climbing, the construction personnel need to manually fix the sliding rail on the poured concrete base through bolts, pins or buckles and other connecting parts. When the formwork frame is lifted along the sliding rail, the fixed parts need to be manually loosened, the position of the sliding rail needs to be adjusted and then locked again. This process is inefficient, and the operation needs to be repeated many times on each floor of the high-rise building, which consumes a lot of time and labor, and the safety is poor. When working at high altitude, workers are easy to fall in narrow space, and the manual fixing of the sliding rail may cause the sliding rail to shake, affecting the overall stability. The labor intensity is large, and the workers need to overcome their own gravity and friction when adjusting the sliding rail, which is easy to cause physical strain to the workers. This mode of manually fixing the sliding rail is contrary to the core concept of "automatic climbing" of the hydraulic creeping formwork, which restricts the improvement of construction efficiency and does not meet the needs of modern building engineering intelligence and few people. Therefore, a hydraulic creeping formwork lifting device and a convenient lifting method thereof are needed to solve the above problems. SUMMARY
