Description

Technical Field

[0001] This utility model relates to the field of adjustable support technology, and in particular to a modular sliding formwork size adjustable support for vertical shafts. Background Technology

[0002] Vertical shafts are important passage structures used in underground engineering projects such as mines and tunnels for vertical or near-vertical transportation of personnel, equipment, and materials, as well as for hoisting ore or waste rock. Slipform construction is a construction technique for cast-in-place concrete engineering. Compared with conventional construction methods, this technique has advantages such as fast construction speed, high degree of mechanization, saving on the materials and labor required for formwork and scaffolding, and the ability to easily disassemble and flexibly assemble and reuse formwork. Modular slipform size adjustment brackets are used in conjunction with vertical shaft slipform systems and can provide support according to the shape requirements of the vertical shaft.

[0003] In existing technologies, vertical steel bars are often used as the main supporting components in current engineering construction scenarios. However, vertical steel bars are often quite long. When construction workers use vertical steel bars for support operations, they need to tie the vertical steel bars in multiple places, which makes the operation cumbersome and time-consuming. This not only significantly reduces construction efficiency, but also easily leads to safety hazards in the support structure due to insecure tying or operational errors, affecting the quality and progress of the entire project. Therefore, it is necessary to improve the modular slipform template size adjustment bracket for vertical shaft shafts to solve the above problems. Utility Model Content

[0004] To overcome the problem that vertical reinforcing bars are often quite long, construction workers need to tie them in multiple places when using them for support, which makes the operation cumbersome and time-consuming.

The smooth rod is disposed inside the rotating bracket, the rotating bracket is disposed between the fixed frame and the rotating frame, and the threaded rod is threadedly connected inside the threaded block.

[0006] As a preferred option, four sets of limiting frames are provided, and the four sets of limiting frames are distributed on the main reinforcing bars from left to right.

[0007] Preferably, the limiting frame has through holes at the corresponding positions of the vertical reinforcing bars, and the vertical reinforcing bars are placed inside the through holes of the limiting frame.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 - Figure 6This utility model provides an embodiment of a modular slipform template size adjustment bracket for a vertical shaft, including an F-shaped steel frame 1, auxiliary components disposed between the F-shaped steel frames 1, main reinforcing bars 21 fixedly connected between the F-shaped steel frames 1, a limiting frame 22 fixedly connected to the main reinforcing bars 21, a rotating frame 25 rotatably connected inside the limiting frame 22, a fixing frame 26 fixedly connected to the top of the rotating frame 25, a smooth rod 27 fixedly connected between the rotating frame 25 and the fixing frame 26, and a rotatably connected inside the limiting frame 22. The rotating bracket 23, the rotating roller 24 rotatably connected inside the rotating bracket 23, the vertical steel bar 215 set inside the rotating roller 24, the fixing ear 210 fixedly connected to the rotating frame 25, the threaded block 211 rotatably connected inside the fixing ear 210, the rotating block 28 rotatably connected inside the limiting frame 22, the threaded rod 29 rotatably connected inside the rotating block 28, the smooth rod 27 is set inside the rotating bracket 23, the rotating bracket 23 is set between the fixed frame 26 and the rotating frame 25, and the threaded rod 29 is threaded. The main reinforcing bar 21 is fixedly connected to the two F-shaped steel frames 1 by welding inside the threaded block 211. Then, according to the design requirements, the limiting frame 22 is uniformly fixed to the main reinforcing bar 21 by welding at certain intervals. At this time, the vertical reinforcing bar 215 is passed through the through hole of the limiting frame 22. The rotating frame 25 rotates inside the limiting frame 22, causing the three sets of rotating brackets 23 to rotate. The rotating roller 24 inside the rotating bracket 23 clamps and limits the vertical reinforcing bars 215 of different diameters, improving the adaptability of clamping vertical reinforcing bars 215 of different diameters, thus improving the overall support stability. It eliminates the need for multiple bindings of the vertical reinforcing bars 215, saving reinforcing bar binding time, reducing labor intensity, reducing the number of reinforcing bar binding operators, reducing construction costs, and improving safety. The auxiliary component binds the end of the vertical reinforcing bar 215 away from the limiting frame 22 with iron wire to the support frame 32, thereby improving the support stability of the vertical reinforcing bar 215, preventing reinforcing bar tipping accidents, and ensuring construction safety.

[0025] Please see Figure 1 - Figure 5In this embodiment, four sets of limiting frames 22 are provided, which are distributed from left to right on the main reinforcing bars 21. This allows for easy control of the distance between the limiting frames 22 according to construction needs, and enables the limiting frames 22 to be fixed to the main reinforcing bars 21 sequentially by welding, improving practicality. The limiting frames 22 have through holes at corresponding positions of the vertical reinforcing bars 215, which are placed inside the through holes of the limiting frames 22. This allows vertical reinforcing bars 215 of different diameters to pass through the through holes of the limiting frames 22 and then be clamped, improving the limiting stability of vertical reinforcing bars 215 of different diameters and enhancing the adaptability of the device. The rotating bracket 23... Three sets of rotating supports 23 are symmetrically distributed on the limiting frame 22. Each rotating support 23 has a corresponding through slot at the position of the smooth rod 27. The smooth rod 27 is positioned inside the through slot of the rotating support 23, allowing it to rotate via the fixing frame 26 and the rotating frame 25. This rotation drives the rotating support 23 to clamp vertical steel bars 215 of different diameters, improving the device's practicality and adaptability. The fixing frame 26 also has corresponding through slots at the corresponding positions of the three sets of rotating supports 23. The three sets of rotating supports 23 are symmetrically distributed within these slots. The three sets of rotating supports 23 clamp the vertical steel bars 215 via rotating rollers 24. When in position, avoid contact between the fixed frame 26 and the rotating bracket 23 to improve the clamping stability of the rotating bracket 23. One end of the threaded rod 29 is fixedly connected to the first limiting plate 212, and the threaded rod 29 is fixedly connected to the second limiting plate 214. The second limiting plate 214 is rotatably connected inside the rotating block 28. The end of the threaded rod 29 away from the first limiting plate 212 is fixedly connected to the knob 213. The main reinforcing bar 21 is fixedly connected between the two F-shaped steel frames 1 by welding. Then, according to the design requirements, the limiting frame 22 is fixedly and evenly welded to the main reinforcing bar 21 at a certain interval. At this time, the vertical reinforcing bar 215 is passed through the through hole of the limiting frame 22. At this point, by holding the vertical reinforcing bar 215 with one hand and rotating the threaded rod 29 with the other, the threaded block 211 is threadedly connected to the outside of the threaded rod 29, thereby driving the rotating frame 25 to rotate inside the limiting frame 22, which in turn rotates the three sets of rotating brackets 23. The rotating rollers 24 inside the rotating brackets 23 clamp and limit the vertical reinforcing bars 215 of different diameters, improving the adaptability to clamping vertical reinforcing bars 215 of different diameters, thus improving the overall support stability. It eliminates the need to tie the vertical reinforcing bars 215 in multiple places, saving reinforcing bar tying time, reducing labor intensity, reducing the number of reinforcing bar tying operators, reducing construction costs, and improving safety.

[0026] Please see Figure 6In this embodiment, the auxiliary components include a connecting frame 31 fixedly connected to the inner side of the F-shaped steel frame 1 and a support frame 32 fixedly connected to the inner side of the connecting frame 31. The end of the vertical reinforcing bar 215 away from the limiting frame 22 is in contact with the support frame 32. By binding the end of the vertical reinforcing bar 215 away from the limiting frame 22 to the support frame 32 with wire, the support stability of the vertical reinforcing bar 215 is improved, preventing the reinforcing bar from tipping over and ensuring construction safety. There are two connecting frames 31, which are symmetrically distributed on the inner side of the F-shaped steel frame 1, making it convenient to fix the connecting frames 31 to the inner side of the F-shaped steel frame 1 by welding, thereby improving the overall support stability.

[0027] During operation, the main reinforcing bar 21 is fixedly connected to the two F-shaped steel frames 1 by welding. Then, the connecting frames 31 on both sides of the support frame 32 are fixed to the two F-shaped steel frames 1 by welding. According to the design requirements, the limiting frames 22 are evenly fixed to the main reinforcing bar 21 by welding at certain intervals. At this time, the vertical reinforcing bar 215 is passed through the through hole of the limiting frame 22 to make contact with the support frame 32. Then, by holding the vertical reinforcing bar 215 with one hand and turning the knob 213 with the other hand, the threaded rod 29 is rotated inside the rotating block 28. The rotating block 28 is rotatably connected to the inside of the limiting frame 22, and the threaded block 211 is rotatably connected to the fixing ear 210. The rotation of the threaded rod 29 drives the main reinforcing bar 21 to rotate. The frame 25 rotates inside the limiting frame 22, and is then positioned inside the through groove of the rotating bracket 23 via the smooth rod 27, causing the three sets of rotating brackets 23 to rotate. The rotating roller 24 inside the rotating bracket 23 clamps and limits the vertical steel bars 215 of different diameters, improving the adaptability to clamping vertical steel bars 215 of different diameters and enhancing the overall support stability. The vertical steel bars 215 are then clamped inside the limiting frame 22 in sequence. The end of the vertical steel bar 215 that is in contact with the support frame 32 is tied with iron wire, which provides auxiliary limiting for the other end of the vertical steel bar 215, thus providing overall support. This saves steel bar tying time, reduces labor intensity, and ensures the support quality of the vertical steel bars 215.

[0028] Through the above steps, the main reinforcing bar 21 is fixedly connected between the two F-shaped steel frames 1 by welding. Then, according to the design requirements, the limiting frame 22 is uniformly fixed to the main reinforcing bar 21 by welding at certain intervals. At this time, the vertical reinforcing bar 215 is passed through the through hole of the limiting frame 22. The rotating frame 25 rotates inside the limiting frame 22, causing the three sets of rotating brackets 23 to rotate. The rotating roller 24 inside the rotating bracket 23 clamps and limits the vertical reinforcing bars 215 of different diameters, improving the adaptability of clamping vertical reinforcing bars 215 of different diameters and improving the overall support stability. It eliminates the need to tie the vertical reinforcing bars 215 at multiple points, solving the problem that when the vertical reinforcing bars 215 are often long, construction workers need to tie the vertical reinforcing bars 215 at multiple points when using them for support operations, which makes the operation cumbersome and time-consuming.
