In Block 300, after the independent self-climbing form system has been assembled, trusses may vertically move up or down a plurality of support towers in accordance with one or more embodiments. For example, screw jacks at each connection point between the at least two trusses and the plurality of support towers may vertically move the trusses. The screw jacks may be operated by having each motor and gearbox move the screw jacks up or down a threaded rod. Additionally, in order to keep the threaded rod from rotating, an anti-rotation device (e.g., bolt or nut) may be disposed at an end of the threaded rod. It is further envisioned that one or more sensors may be disposed on or provided within the screw jacks and/or trusses to determine a rate at which the trusses are moving.
In Block 310, once the trusses reach a vertical position for performing operation on the vertical structures, each truss may be leveled to be at a same height in accordance with one or more embodiments. For example, the screw jacks may raise the trusses at a rate such that each truss is horizontal and even for workers to use and meet safety regulations. It is further envisioned that one or more sensors may be used to provide measurements to ensure that the trusses are level. Likewise, during the vertical moving of the trusses, the one or more sensors may provide real-time data to a rate of the vertical movement of each truss.
In Block 320, with the trusses level and at the vertical position for performing operation on the vertical structures, the trusses may be locked at the vertical position on the plurality of support towers with a locking device. For example, the locking device may be an arm extending from an end of each threaded rod of the screw jacks and may be removably bolted to a rigid framework of the plurality of support towers. By locking the trusses, workers may safely access the vertical structures. Additionally, the screw jacks may also be locked. For example, an anti-rotational device may be disposed on the threaded rod such that the threaded rod does not rotate to ensure the screw jacks are non-operational while the trusses are locked.
In Block 330, with the trusses locked, platforms operationally connected to the trusses may be extended or retracted in accordance with one or more embodiments. For example, the platforms surround the vertical structures to allow for workers to access the vertical structures. The platforms may be extended to be adjacent and/or rest against the vertical structures. Additionally, the platforms may be retracted to create space for the vertical structures and allow movement of the trusses without damaging the vertical structures and the components of the independent self-climbing form system.
In Block 340, a determination is made whether the trusses need to be raised or lowered in accordance with one or more embodiments. For example, the vertical structure may be built or repaired in sections based on a required height needed such that the trusses are at the vertical position on the plurality of support towers to build or repair the vertical structure. If the answer to the vertical structure needing being raised or lowered is yes (e.g., building or repairing the vertical structure at other vertical positions), the flowchart will proceed to Block 350. In Block 350, the trusses may be unlocked (e.g., unbolting the arm) and will go back to the Block 300 to repeat the previously mentioned Blocks (300-340). In some embodiments, a position of the trusses may be adjusted in Block 355 prior to returning to the Block 300 from the Block 350. For example, the trusses alignment with respect to the plurality of support towers may be adjusted or leveled such that the trusses are ready to be vertically moved.
However, if the answer to whether the trusses need to be raised or lowered is no, the flowchart will proceed to Block 360. In Block 360, the vertical position of trusses may be maintained in accordance with one or more embodiments. For example, the vertical position is maintained to allow workers to perform operations on the vertical structures. It is further envisioned that the independent self-climbing form system may also be prepared for disassembly in Block 360.
In one or more embodiments, the flowchart of
With respect to the embodiments discussed above in the Figures illustrating various views of the independent self-climbing form system (100), various procedures may be automated to provide faster delivery time in comparison to manual methods for preparing and transmitting building operations. For example, a movement of the trusses may be programmed to automatically occur based on a height of the vertical structure. Moreover, the platforms extending or retracting may be programmed to automatically occur based on a shape and size of the vertical structure or based on a movement of the trusses, for example.
Implementations herein for operating the independent self-climbing form system (100) may be implemented on a computing system coupled to a controller. Any combination of mobile, desktop, server, router, switch, embedded device, or other types of hardware may be used with the emulsion generating system (100, 200, 300). For example, as shown in
The computing system 400 may also include one or more input devices 410, such as a touchscreen, keyboard, mouse, microphone, touchpad, electronic pen, or any other type of input device. Additionally, the computing system 400 may include one or more output devices 408, such as a screen (e.g., a liquid crystal display (LCD), a plasma display, touchscreen, cathode ray tube (CRT) monitor, projector, or other display device), a printer, external storage, or any other output device. One or more of the output devices may be the same or different from the input device(s). The input and output device(s) may be locally or remotely connected to the computer processor(s) 402, non-persistent storage 404, and persistent storage 406. Many different types of computing systems exist, and the aforementioned input and output device(s) may take other forms.

Data may also be presented through various audio methods. In particular, data may be rendered into an audio format and presented as sound through one or more speakers operably connected to a computing device. Data may also be presented to a user through haptic methods. For example, haptic methods may include vibrations or other physical signals generated by the computing system. For example, data may be presented to a user using a vibration generated by a handheld computer device with a predefined duration and intensity of the vibration to communicate the data.
As described above, embodiments herein are directed toward an independent self-climbing form system that may be used to erect, build, repair, or otherwise work on a structure. The independent self-climbing form system may be used in a manner that minimizes or eliminates the need to anchor to or otherwise interact with the structure, other than to perform the desired work. Additionally, the moving internal platforms provided at one or multiple levels may allow for unique shaped structures to be accommodated. Further, the independent self-climbing form system may be altered in height in real time corresponding to a height of the structure being worked such that the height of the independent self-climbing form system is not fixed. Furthermore, the independent self-climbing form system may include housing for workers to remain on site during down time to allow for easy and quick startup.
While the invention has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments can be devised which do not depart from the scope of the invention as disclosed herein. Accordingly, the scope of the invention should be limited only by the attached claims.
