Description

Technical Field

[0001] The present invention relates to the field of construction technology, and specifically to an intelligent clamp-type self-lifting climbing formwork device. The device integrates a hydraulic climbing mechanism, a self-lifting system, a formwork system and an automatic control system to realize the automatic climbing, self-lifting and demolding operations of the formwork during the construction of high-rise buildings or large structures, thereby greatly improving construction efficiency and safety. Background Art

[0002] In the construction process of high-rise buildings, vertical transportation of formwork has become a technology-intensive and crucial link. Traditional methods, whether relying on manpower or basic mechanical devices, have exposed significant drawbacks. Manual operation is not only inefficient, pushing up labor costs, but also slowing down the progress of the project. Although mechanical assistance has improved, its complex structure, cumbersome operating procedures and high-skilled operator requirements may endanger construction safety and quality due to human errors. More importantly, the traditional formwork system lacks advanced automated control and safety assurance mechanisms during lifting, which increases safety hazards such as formwork falling off and tilting, posing a potential threat to on-site personnel and the environment.

[0003] In recent years, the leap forward in building technology and the promotion of the trend of intelligence have prompted the self-climbing formwork system (also known as climbing formwork or jumping formwork, internationally used) to emerge in the field of high-rise buildings. The system integrates climbing formwork, climbing frame (some designs can be omitted) and advanced climbing equipment, and is tailored for high-rise structures such as shear walls, cylinders and bridge piers. Its self-climbing characteristics significantly reduce the dependence on external lifting machinery and reduce lifting operations. At the same time, the built-in scaffolding design eliminates the need for additional external scaffolding, thereby improving construction efficiency, reducing costs, and showing good economic benefits. The self-climbing formwork system combines the advantages of large formwork and sliding formwork, and is particularly suitable for the construction needs of super-high-rise buildings. It is close to the vertical structure of the building and climbs layer by layer as the construction progresses, which not only saves construction space, but also does not require additional vertical transportation equipment. In addition, its equipped operating scaffolding and stable safety enclosure provide a reliable safety barrier for construction, especially suitable for multi-story or high-rise building construction with limited space.

[0004] However, the current development of self-climbing formwork systems is not without challenges. Some systems have complex designs and cumbersome installation and disassembly processes, which invisibly increase the difficulty and cost burden of construction. At the same time, the uneven level of intelligence has led to the lack of precise automatic control and real-time monitoring capabilities in some systems, making it difficult to flexibly respond to changing construction conditions. Furthermore, the stability and safety of the formwork during the climbing process still need to be paid attention to. Ensuring the firm connection between the formwork and the concrete structure and preventing accidents such as accidental falling off or tilting are technical problems that need to be solved urgently.

[0005] In view of the above problems, it is particularly important to develop an intelligent clamp-type self-lifting climbing formwork device which has a simple structure, convenient operation, high intelligence, and safety and reliability. Summary of the invention
