Abstract
Description
Technical Field
[0001] The present invention relates to the field of building technology, and in particular to an intelligent clamp-type self-climbing formwork device, which realizes automatic climbing and adjustment of the formwork structure in high-rise building construction by integrating hydraulic drive, automatic control and formwork system, thereby improving construction efficiency and safety. Background Art
[0002] In the field of high-rise building construction, the vertical lifting of formwork is a vital and technically demanding link. Traditional methods of lifting formwork for high-rise buildings mainly rely on manual or simple mechanical devices, and these methods have many significant problems. First, the manual lifting method is inefficient, which not only increases labor costs but also prolongs the construction period. Secondly, although the mechanical lifting method has improved efficiency to a certain extent, it is often complex in structure, cumbersome to operate, and requires a high level of technical skills from the operator, which can easily lead to operational errors, thus affecting construction safety and project quality. In addition, traditional formwork systems often lack effective automatic control and safety measures during the lifting process, which can easily lead to safety accidents such as formwork falling off or tilting, posing a serious threat to construction personnel and the surrounding environment.
[0003] In recent years, with the continuous advancement of construction technology and the improvement of the level of intelligence, the self-climbing formwork system has gradually become a new favorite in high-rise building construction. Climbing formwork is the abbreviation of climbing formwork, also known as jumping formwork abroad. It consists of three parts: climbing formwork, climbing frame (some climbing formworks do not have climbing frames) and climbing equipment. It is an effective tool in the construction of shear wall systems, cylinder systems, bridge piers and other tall structures. Due to its self-climbing ability, it does not require lifting machinery, which reduces the lifting workload of transportation machinery during construction. Hanging scaffolding on the self-climbing formwork can save the external scaffolding during the construction process. In summary, climbing formwork can reduce the number of lifting machinery and speed up construction, so the economic benefits are better. Climbing formwork is a formwork technology that combines the processes and characteristics of large formwork and sliding formwork. It has the common advantages of large formwork and sliding formwork, and is particularly suitable for super high-rise building construction. Like sliding formwork, it is attached to the vertical structure of the building during the structural construction phase and rises layer by layer as the structure is constructed. In this way, the formwork does not occupy the construction site and does not require other vertical transportation equipment. In addition, it is equipped with an operating scaffolding and has reliable safety enclosures during construction, so there is no need to set up external scaffolding. It is particularly suitable for building multi-story or high-rise buildings on a relatively narrow site.
[0004] However, the existing self-climbing formwork systems still face many challenges. On the one hand, the structure of some systems is too complex, and the installation and disassembly process is cumbersome, which increases the difficulty and cost of construction; on the other hand, some systems are not highly intelligent, lack precise automatic control and real-time monitoring functions, and are difficult to cope with complex and changing construction environments. In addition, some systems also lack stability and safety during the climbing process, and cannot ensure a stable connection between the formwork and the concrete structure, which is prone to accidents such as accidental falling off or tilting.
[0005] In view of the above problems, it is particularly important to develop an intelligent clamp-type self-climbing formwork device with simple structure, convenient operation, high intelligence, safety and reliability. Summary of the invention

[0048] When the present invention is implemented, its implementation mode can be described in detail as follows:
[0049] Initial state: All clamps are in a locked state, and the formwork body is attached to the poured concrete surface. Figure 2 .
[0050] Step 1: Extend the hydraulic locking piece of the lower layer (i.e., the first hoop) to separate the first hoop from the concrete surface, in preparation for the subsequent climbing action.
[0051] Step 2: Retract the climbing cylinder to drive the first hoop, the second hoop and part of the climbing frame load-bearing beam to move upward to the specified position. At this time, the third hoop is still fixed in the original position to provide support for the overall structure. Figure 3 .
[0052] Step 3: Retract the lower hydraulic locking piece and re-tighten the first clamp to ensure that it is firmly connected to the concrete surface at the new height.
[0053] Step 4: Start the formwork ejection cylinder and retract it backward to separate the formwork body from the concrete surface, creating conditions for the disassembly and reinstallation of the formwork.
[0054] Step 5 to Step 7: Repeat the above steps, but for the second and third clamps. First, extend the hydraulic locking piece of the upper layer (i.e., the second clamp) to separate it from the concrete surface; then extend the jacking cylinder (i.e., the original climbing cylinder) to move the formwork, plate and upper clamp (i.e., the third clamp) upward to the specified position as a whole; finally, retract the lower hydraulic locking piece and re-lock the second clamp. At this time, the third clamp has reached a new height and is locked on the concrete surface. Figure 2 .
[0055] Step 8: Start the formwork demolding cylinder again, but this time extend it forward so that the lower end of the formwork fits the newly poured concrete surface, preparing for the next concrete pouring.
[0056] Repeat operation: Repeat the operation process from step 1 to step 8 to realize the continuous climbing of the formwork device and the concrete pouring operation.
[0057] The present invention provides an intelligent clamp-type self-climbing formwork device, which realizes automatic climbing and adjustment of the formwork structure by integrating hydraulic drive, automatic control and formwork system, thereby improving construction efficiency and safety. Through the above implementation, the following advantages are achieved:
