Description

Technical Field

[0001] This invention relates to the field of hydraulic climbing formwork technology, specifically to a hydraulic climbing formwork device and its control system. Background Technology

[0002] Hydraulic climbing formwork is a new technology combining slipform and scaffolding. It absorbs the advantages of scaffolding, such as simple labor organization and construction management, less susceptibility to external conditions, and easier assurance of concrete surface quality, while avoiding common defects in slipform construction, allowing construction deviations to be eliminated layer by layer. In terms of climbing method, it is the same as slipform; the lifting frame, formwork, operating platform, and scaffolding are powered by hydraulic jacks to climb upwards independently, eliminating the need for repeated tower crane assembly and disassembly, layer-by-layer line laying, and scaffolding erection. Reinforcing steel is tied as it rises, ensuring safe operation. After one project is completed, the formwork, climbing device, and hydraulic equipment can be reused in other projects, allowing for high reusability. However, existing hydraulic climbing formwork equipment is cumbersome and complex to operate during the ascent process, has a slow ascent speed, poor flexibility, and certain safety risks. The overall safety factor of existing climbing frames is relatively low, the connection stability between the climbing frame and the building is poor, and there are no other safety aids. Therefore, this paper proposes a hydraulic climbing formwork device and control system. Summary of the Invention

The steel frame column is positioned around the concrete base at the bottom of the building. Guide rails are installed around the perimeter of the building.

[0022] The inside of the cable winding box 7 is equipped with a drive motor 701, a gearbox 702, a winding rod 703, and a bearing 704. The gearbox 702 is bolted to the bottom of the inside of the cable winding box 7. The drive motor 701 is bolted to one side of the gearbox 702. The winding rod 703 is mounted on the gear inside the gearbox 702. One end of the winding rod 703 is connected to the bearing 704.

[0023] The winding rod 703 is wound with steel cable 8. The steel frame column 4 is made up of several standard tower sections that are fixed to each other by bolts. There are four steel frame columns 4, which are distributed at the four corners of the concrete base 6. The bottom of the steel frame column 4 is fixedly connected to the embedded parts on the concrete base 6.

[0024] The top frame 5 is bolted to the top of the steel frame column 4, connecting the four steel frame columns 4 together. The first fixed pulley 11 is bolted to the top frame 5.

[0025] The upper mold frame 1, the protective frame 2, and the lower mold frame 3 are all equipped with steel cable connectors 13 on their four sides. The steel cable connectors 13 are provided with through holes for the steel cable 8 to pass through. One end of the steel cable 8 is fixed to the steel cable connector 13 at the bottom of the lower mold frame 3 by a steel cable fastener 17.

[0026] The inner frame plate 15 is fixedly connected to the upper mold frame 1 and the lower mold frame 3 through a connecting frame. The guide rail groove 16 on the inner frame plate 15 is movably connected to the guide rail 10. The inner frame plate 15 of the upper mold frame 1 and the lower mold frame 3 is fixedly connected to the building 9.

[0027] The lower mold frame 3 is equipped with a hydraulic oil pump and a hydraulic oil tank. The hydraulic oil pump is connected to the hydraulic oil tank and the hydraulic cylinder 14 through hydraulic oil pipes. The hydraulic cylinder 14 is installed on the inner side of the lower mold frame 3 by bolts.

[0028] A control system for a hydraulic climbing formwork device includes an upper formwork lifting system and a lower formwork lifting system. The upper formwork lifting system is connected to a hydraulic oil pump, and the lower formwork lifting system is connected to a drive motor 701.

[0029] The above embodiment describes the usage method of a hydraulic climbing formwork device and control system. During installation, a concrete base 6 is first poured. Then, steel frame columns 4 are installed according to the set height of the building. The steel frame columns 4 are constructed using several standard tower sections. A tower crane is then used to install the top frame 5 on the top of the steel frame columns 4. Next, the lower formwork frame 3 is constructed, and then a tower crane is used to place the lower formwork frame 3 onto the building 9. The inner frame plate 15 on the inner side of the lower formwork frame 3 is fixedly connected to the building 9. Then, the upper formwork frame 1 is constructed. After the upper formwork frame 1 is constructed, it is lifted by a tower crane and placed onto the building 9, ensuring the bottom plate of the upper formwork frame 1 contacts the bottom of the lower formwork frame 3. The bottom of the upper formwork frame 1 is then fixedly connected to the hydraulic cylinder 14 using bolts. The inner frame plate 15 on the inner side of the upper formwork frame 1 is then fixedly connected to the building 9. A construction platform is then constructed on the upper formwork frame 1. When construction is completed, the guide rail 10 is installed on the building, and the connecting parts between the upper formwork frame 1 and the building are disassembled. Ascending is required... During the construction of the platform, the hydraulic oil pump is directly controlled by the upper formwork lifting system to supply hydraulic oil to the hydraulic cylinder 14, allowing the hydraulic cylinder 14 to rise slowly, thereby raising the upper formwork 1 to a suitable height. Then, the upper formwork 1 is fixed. When the upper formwork 1 rises, it is raised vertically by the guide rail 10. After the upper formwork 1 is fixed to the building, the connecting parts of the lower formwork 3 to the building are disassembled. Then, the drive motor 701 is controlled by the lower formwork lifting system to work, thereby driving the gear in the reduction gearbox 702 to rotate, thereby driving the winding rod 703 to rotate around the bearing 704. The winding rod 703 is used to wind up the steel cable 8. At the same time, the hydraulic oil pump is turned on to draw the hydraulic oil in the hydraulic cylinder into the hydraulic oil tank, allowing the lower formwork 3 to rise slowly under the action of traction. When the lower formwork 3 rises to the bottom of the upper formwork 1, the rise stops, and the lower formwork 3 is fixed to the building. The fixing holes are the original fixing holes of the upper formwork 1.
