Description

Technical Field

[0001] This utility model patent relates to the field of steel formwork lifting technology, and more specifically, to a steel formwork lifting structure for variable cross-section semi-circular support piles. Background Technology

[0002] The one-time pile construction technology for the variable cross-section semi-circular interlocking piles at the top of the foundation pit adopts a prefabricated semi-circular steel mold. During the pile casting process, the semi-circular steel mold is vertically inserted into the hole, close to the side wall of the pile hole, and merged with the upper semi-circular steel cage to form an integral structure. After the steel mold is accurately positioned, it is fixed at the hole opening. The guide pipe is extended section by section and lowered into the hole from the semi-circular steel cage. Then, the pile body concrete is poured. After the concrete has initially set, the steel mold is pulled out, and the variable cross-section interlocking piles with a lower circular shape and a top semi-circular shape are cast in one go.

[0003] However, when lifting a semi-cylindrical steel mold, because the main body of the steel mold is semi-circular, conventional lifting structures cannot maintain the balance of the main body of the steel mold, which can easily cause the steel mold to sway after lifting, affecting construction safety.

[0026] Reference Figures 1-5 The image shown is a preferred embodiment of the present invention.

[0027] The lifting structure for the steel formwork of the variable cross-section semi-circular support pile includes a steel formwork body 1, a lifting ring 19, and steel wire ropes 4. The steel formwork body 1 is provided with a back plate 21 and a web plate 22. The back plate 21 is welded to the web plate 22. The back plate 21 and the web plate 22 are perpendicular to each other. Both the back plate 21 and the web plate 22 have through holes 2. The lifting ring 19 is connected to the through holes 2. The steel wire ropes 4 are connected to the lifting ring 19. The three steel wire ropes 4 converge and connect to the shaped groove lifting end. The lifting end is connected to the lifting hook 5. The steel wire ropes 4 are connected to the fixing mechanism 6. The lifting ring 19 is clamped with a connecting block 3.

[0028] With the provided back plate 21 and web plate 22, when lifting the steel mold body 1, two symmetrical lifting rings 19 are arranged on the back plate 21, and a separate lifting ring 19 is set on the web plate 22, so that the three lifting rings 19 form an equilateral triangle. The three lifting rings 19 are respectively connected to steel wire ropes 4, and the three steel wire ropes 4 are gathered and connected to form a lifting end. The lifting hook 5 is connected to the lifting end, so that the steel mold body 1 can be kept stable during the lifting process, which is convenient for lifting the steel mold.

[0029] Specifically, in this embodiment, the outer surface of the steel mold body 1 is coated with a release agent.

[0030] The use of a release agent facilitates the subsequent demolding and pulling out of the main body of the steel mold 1.

[0031] Specifically, in this embodiment, the interior of the steel mold body 1 is filled with sandbags or clay during the hoisting process, which increases the self-weight of the steel mold body 1, making it easier for the steel mold body 1 to sink during installation and preventing the steel mold from floating during subsequent concrete pouring.

[0032] Specifically, in this embodiment, the connection points of the three steel wire ropes 4 connected to the back plate 21 and the web plate 22 form an equilateral triangle, which can maintain the stability of the steel mold body 1 after lifting.

[0033] Specifically, in this embodiment, the lifting ring 19 is provided with two symmetrical docking blocks 17, the connecting block 3 is provided with two docking grooves 20 that are adapted to the docking blocks 17, the connecting block 3 is provided with a transmission cavity 9 that communicates with the two docking grooves 20, the transmission cavity 9 is rotatably installed with a transmission gear 11, the transmission cavity 9 is slidably installed with two transmission sliders 12, the transmission sliders 12 are provided with tooth grooves that mesh with the transmission gears 11, both transmission sliders 12 are provided with locking blocks, and both docking blocks 17 are provided with locking grooves 18 that are adapted to the locking blocks.

[0034] Through the cooperation of structures such as the docking block 17, docking groove 20, and locking block, when docking the lifting ring 19 with the through hole 2 on the back plate 21 or web plate 22, the lifting ring 19 is first passed through the through hole 2, and then the connecting block 3 is fastened to the lifting ring 19. At this time, the two docking blocks 17 on the lifting ring 19 are inserted into the two docking grooves 20 on the connecting block 3. Then, by rotating the transmission gear 11, the locking blocks on the two transmission sliders 12 are driven to be inserted into the locking grooves 18 on the docking block 17, thereby achieving the locking and fixing between the lifting ring 19 and the connecting block 3. This facilitates the disassembly and assembly of the lifting ring 19 and the steel membrane body, simplifies the disassembly and assembly process of the conventional lifting ring 19, and improves work efficiency.

[0035] Specifically, in this embodiment, two symmetrical mounting blocks 13 are arranged in the transmission cavity 9. A guide rod 15 protrudes from the mounting block 13. A sliding hole 16 adapted to the guide rod 15 is opened on the transmission slider 12. A return spring 14 is sleeved on the guide rod 15. One end of the return spring 14 abuts against the mounting block 13, and the other end of the return spring 14 abuts against the transmission slider 12.

[0036] With the provided sliding hole 16, guide rod 15, and return spring 14, the mounting block 13 can slide along the guide rod 15 through the sliding hole 16, guiding the movement direction of the mounting block 13. The return spring 14 enables the mounting block 13 to automatically return to its original position, and in normal conditions, the two transmission sliders 12 are always kept away from each other, so that the two locking blocks are always pressed against the locking groove 18, thereby ensuring the connection stability between the lifting ring 19 and the connecting block 3.

[0037] Specifically, in this embodiment, the transmission gear 11 is connected to an adjustment knob 10 extending to the outside. The adjustment knob 10 is provided with anti-slip grooves spaced apart along the circumferential direction, and the transmission gear 11 can be adjusted by adjusting the adjustment knob 10.

[0038] Specifically, in this embodiment, the fixing mechanism 6 is provided with a U-shaped groove that can accommodate the wire rope 4 and a fixing groove that communicates with the U-shaped groove. An abutment block 7 is slidably installed in the fixing groove and is fixed in the fixing groove by a fixing bolt 8.

[0039] Through the cooperation of structures such as the U-shaped groove and the abutment block 7, the steel wire rope 4 can be placed in the U-shaped groove after the length is adjusted, and then the abutment block 7 can be fastened into the fixing groove. Finally, the fixing bolt 8 is turned to make the abutment block press against the steel wire rope 4 and then fixed. This makes it easy to adjust the length of the steel wire rope 4 according to the actual situation to ensure the balance of the steel formwork body 1 during lifting.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
