Description

Technical Field

[0001] This utility model relates to the field of slipform construction technology for silos in civil engineering, and in particular to a slipform device for ultra-large diameter silo walls without internal support. Background Technology

[0002] As core facilities for large-scale storage of bulk materials in the industrial and agricultural sectors, ultra-large diameter silos place extremely high demands on silo wall construction due to their large inner diameter. To address the problems of low efficiency, high cost, and insufficient safety of traditional formwork methods for ultra-large diameter silos, a sliding formwork device without internal support for ultra-large diameter silos has been developed.

[0003] The slipform device for ultra-large diameter silo walls without internal support is an innovative piece of equipment developed specifically to solve the construction challenges of ultra-large diameter silo walls. With modular templates as its core, it enables continuous sliding pouring along the concrete surface of the silo wall. Its design is fully adapted to the curved structure of ultra-large diameter silo walls, ensuring the integrity and verticality of the concrete pouring while eliminating the need for internal support construction and dismantling, significantly reducing material consumption and construction costs.

[0004] Although the slipform device without internal support for the walls of ultra-large diameter cylindrical warehouses significantly improves construction efficiency and operational safety, the device is susceptible to external interference. In cases of strong winds, uneven stress on the lifting frame, or template misalignment, the device will experience lateral displacement or torsion, leading to excessive deviations in the verticality of the warehouse walls and even posing safety risks such as template deformation and collapse. The existing solution is to rationally arrange the number of lifting gantry frames and jacks, ensuring their even distribution, and uniformly reinforcing the lifting gantry frames. However, while rationally arranging the lifting gantry frames can enhance stability to some extent, its resistance to strong winds or sudden earthquakes remains limited. Furthermore, it is greatly affected by the skill level of the construction personnel, and deviations during installation can lead to platform deformation. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sliding formwork device for ultra-large diameter cylindrical warehouse walls without internal support, aiming to improve the problem of existing measures for the reasonable arrangement of lifting gantry frames being affected by the operating level of construction personnel.

[0014] As a further description of the above technical solution:

[0015] The tension adjustment component includes multiple limit hooks, the outer left side of the multiple limit hooks are slidably connected to the right middle of the multiple template panels on the right side, and multiple limit grooves are opened in the right middle of the multiple template panels on the right side.

The operation is repeated until the liquid level is horizontal. The imbalance is quickly eliminated by dynamic adjustment, and the balance accuracy can be precisely controlled to avoid over-adjustment. After stabilization, the balance state is locked to ensure the overall stability of the device and lay the foundation for construction accuracy and safety. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a sliding formwork device for an ultra-large diameter cylindrical warehouse wall without internal support, comprising a warehouse wall 1, multiple template panels 2, and multiple columns 4. The template panels 2 are in direct contact with the concrete and bear the lateral pressure, impact force, and pressure during the concrete pouring and vibration process. The outer wall of the warehouse wall 1 is provided with an anti-lateral displacement mechanism 3, which is used to resist the lateral displacement generated by the device. The outer wall of the warehouse wall 1 is provided with a leveling mechanism 5, which is used to adjust the balance of the device. The top of each of the multiple columns 4 is fixedly connected with a support frame 8, which serves as the supporting foundation of the operating platform and provides a safe standing and working space for construction personnel. The outer wall of the support frame 8 is provided with a frame mechanism 6, which provides a supporting frame for the device. The outer wall of the support frame 8 is provided with a reinforcement mechanism 7, which reinforces the device.

[0035] The anti-lateral displacement mechanism 3 includes multiple back ribs 301. By arranging the back ribs 301 laterally, the lateral pressure on the panel in the concrete is reduced. The left sides of the multiple back ribs 301 are all fixedly connected to the right side of the right template panel 2. The front sides of the multiple back ribs 301 are all fixedly connected with tenons 302, and the rear sides of the multiple back ribs 301 are all provided with grooves 303. The sliding connection between the tenons 302 and the grooves 303 connects the multiple template panels 2 and increases stability. The top and rear sides of the multiple back ribs 301 are all threaded with bolts 304, and the bottom of the outer wall of the multiple bolts 304 is threaded with nuts 305. The bolts 304 pass through the back ribs 301 and the tenons 302, and the nuts 305 then pass through the back ribs 301 and the tenons 302. To reinforce the connection between the template panels 2, a washer 306 is slidably connected to the top of the outer wall of multiple bolts 304. The washer 306 is used to reduce vibration. Threaded grooves 307 are opened on the rear side of the top of multiple back ribs 301. The threaded grooves 307 facilitate the installation of bolts 304. Two perforated hooks 308 are fixedly connected to the right side of multiple template panels 2. Springs 309 are fixedly connected to the adjacent side of multiple perforated hooks 308. The connection between multiple template panels 2 is reinforced by the perforated hooks 308 and springs 309. Tension adjustment components 310 are provided on the right side of multiple template panels 2. Tension adjustment components 310 are used to adjust the tension of springs 309.

[0036] The tension adjustment assembly 310 includes multiple limit hooks 3101. The left side of the outer wall of the multiple limit hooks 3101 is slidably connected to the middle right side of the multiple template panels 2 on the right side. Multiple limit grooves 3102 are opened in the middle right side of the multiple template panels 2 on the right side. The front hook of the limit hook 3101 is connected to the spring 309, and the rear hook is slidably connected to the limit groove 3102, thereby adjusting the tension of the spring 309.

[0037] Specifically, during the installation of the anti-lateral displacement mechanism 3, multiple template panels 2 are arranged circumferentially along the outer wall of the bin 1, allowing the tenons 302 of adjacent back ribs 301 to slide into the grooves 303, forming a preliminary meshing connection through the mortise and tenon structure, thus limiting the lateral displacement of the sliding membrane structure. Subsequently, bolts 304 are inserted into the threaded grooves 307 at the top of the back ribs 301, with the bolts 304 passing through the through holes corresponding to the tenons 302 on the back ribs 301. After fitting a washer 306, the nut 305 is tightened. The washer 306 can buffer vibration and prevent loosening. The threaded connection between the bolts 304 and the nut 305 strengthens the mortise and tenon connection, improving the performance of the component. The shear strength between them is improved to prevent the joint from cracking due to the lateral pressure of the concrete. At the same time, the two ends of the spring 309 are hung on the perforated hooks 308 of the adjacent template to generate a preliminary pre-tension force. Then, the front side of the limiting hook 3101 is hooked to the middle of the spring 309, and the rear side of the limiting hook 3101 is inserted into the different limiting grooves 3102 on the right side of the template. The pre-tension force is adjusted by changing the tension length of the spring 309 to continuously counteract the lateral thrust and prevent the template panel 2 from shifting due to external force. The template panel 2 is connected into a whole through triple constraint, which effectively resists the lateral pressure and avoids deviation of the verticality of the silo wall 1 and deformation of the template panel 2.

[0038] Reference Figure 2 , Figure 4 and Figure 6 The leveling mechanism 5 includes an annular slide bar 501. The left side of the annular slide bar 501 is fixedly connected to the right side of multiple columns 4 on the right side. A groove 502 is provided at the bottom of the annular slide bar 501. A slider 503 is slidably connected to the inner wall of the groove 502. The position is adjusted by the sliding connection between the slider 503 and the groove 502. A counterweight box 504 is fixedly connected to the bottom of each slider 503. The counterweight box 504 is used to place gravity components. A gravity block 505 is fixedly connected to the inner wall of each counterweight box 504. The overall balance of the device is adjusted by adjusting the position of the gravity block 505. A fixing rod 506 is rotatably connected to the right side of the outer wall of each counterweight box 504. Multiple fixing grooves 507 are provided on the right side of each column 4 on the right side. The fixing rod 506 can engage with the fixing groove 507, thereby limiting the position of the counterweight box 504. A balance test component 508 is provided on the right side of each column 4 on the right side. The balance test component 508 is used to detect and display the balance at each position.

[0039] The balance test assembly 508 includes multiple acrylic tubes 5081, each filled with a colored liquid. The left ends of the multiple acrylic tubes 5081 are fixedly connected to the right side of multiple columns 4 on the right side. Multiple horizontal scale lines 5082 are opened on the outer wall of the multiple acrylic tubes 5081.

[0040] Specifically, when adjusting the balance of the device, first observe the alignment of the colored liquid in the acrylic tubes 5081 on each column 4 with the horizontal scale line 5082 to determine the tilt direction of the device. During adjustment, loosen the fixing rod 506 of the counterweight box 504 on the higher side, so that the fixing rod 506 is disengaged from the fixing groove 507 opened in the column 4. Push the counterweight box 504 to drive the slider 503 to slide along the sliding groove 502 of the annular slide rod 501 to the lower side. During the sliding process, adjust the weight by increasing or decreasing the number of gravity blocks 505 in the counterweight box 504 until the liquid level of the corresponding acrylic tube 5081 is flush with the scale line. Finally, lock the fixing rod 506 into the fixing groove 507 at the current position. Repeat the operation until the liquid level in all acrylic tubes 5081 is aligned with the horizontal scale to complete the overall leveling, ensuring the device is balanced and stable. This allows the device to be leveled quickly, improving the stability of the device and ensuring construction accuracy and safety.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The frame mechanism 6 includes multiple large horizontal beams 601, with each adjacent side of the large horizontal beams 601 fixedly connected to the opposite side of multiple template panels 2. Two small horizontal beams 602 are fixedly connected to the opposite side of each template panel 2. Both the large and small horizontal beams 601 and 602 are used for supporting the device. The reinforcement mechanism 7 includes two channel steel rings 701, with the left sides of each channel steel ring 701 fixedly connected to the right sides of the multiple template panels 2 and the multiple columns 4 on the right side. Reinforcing rings 702 are fixedly connected to the right sides of the multiple columns 4 on the right side. Steel rings 701 and reinforced rings 702 are used to increase the stability of the device. Foot pedals 9 are fixedly connected to the opposite sides of the multiple columns 4. The foot pedals 9 are convenient for workers to operate. Guardrails 10 are fixedly connected to the opposite sides of the multiple foot pedals 9. The guardrails 10 are used to protect workers. Multiple support rods 11 are fixedly connected to the outer walls of the multiple support frames 8. The support rods 11 provide vertical support, ensure structural stability and transmit force. Multiple feed holes 12 are opened on the outer walls of the multiple support frames 8. The feed holes 12 are convenient for stacking the bin wall 1.

[0042] Specifically, when installing the slipform device, multiple large horizontal beams 601 are first horizontally connected to the outside of the template panel 2, with adjacent large horizontal beams 601 forming the main support frame. Then, small horizontal beams 602 are fixed on the side of the template panel 2 away from the silo wall 1, intersecting with the large horizontal beams 601 to form a grid support structure, enhancing the overall rigidity of the template. Subsequently, two channel steel rings 701 are fixed to the outer wall of the right template panel 2 and the column 4. Then, a reinforcing ring 702 is added to the outside of the column 4, forming a double circumferential constraint with the channel steel ring 701, improving the device's resistance to deformation. Next, a foot pedal 9 is fixed to the outside of the column 4, placing the foot pedal 9 above the large horizontal beam 601 for workers to stand and operate. The foot pedal 9 and the edge of the large horizontal beam 601 are welded with guardrails 10 to form a safety protection. Finally, a feed hole 12 is opened on the outer wall of the support frame 8 to facilitate concrete pouring. At the same time, a support rod 11 is fixed to the top of the support frame 8 to vertically support the overall structure and transmit tension, completing the installation of the frame mechanism 6 and the reinforcing mechanism 7.

[0043] Working principle: The tenon 302 and groove 303 of adjacent back ribs 301 form a mortise and tenon connection, which restricts the lateral movement of the template panel 2 by physical interlocking, providing a basic rigid frame for the overall structure and preventing the displacement of individual template pieces. Then, the bolt 304 passes through the back rib 301 and the tenon 302 and is threaded with the nut 305 to lock the mortise and tenon connection. The threaded connection eliminates the splicing gap, greatly improves the vibration and misalignment strength, and thus resists the pressure of the concrete side, preventing the connection from cracking due to gaps. The gasket 306 buffers construction vibration through elastic deformation, preventing the bolt 304 from loosening and causing constraint failure. Finally, the spring 309 applies continuous tension to the adjacent template panel 2 through the hook with holes 308. The cooperation between the limit hook 3101 and different limit grooves 3102 can adjust the tension, keeping the template panel 2 in a taut state, offsetting the misalignment caused by lateral thrust, connecting the dispersed template panels 2 into an integral force-bearing structure, effectively resisting various lateral tensions, and ensuring the verticality of the warehouse wall 1 and the stability of the template.

[0044] Furthermore, by observing the colored liquid inside the acrylic tube 5081 using the principle of horizontality, the deviation between the liquid level and the scale line visually displays the tilt state of the device, providing precise guidance for adjustment. When the device is tilted, the fixing rod 506 of the counterweight box 504 on the higher side is disengaged from the fixing groove 507, and the slider 503 slides along the groove 502 of the annular slide rod 501, causing the counterweight to shift to the lower side. The gravity block 505 counteracts the tilting trend, and the weight of the counterweight box 504 can be finely adjusted by adding or removing the gravity block 505, achieving control of balance accuracy and avoiding over-adjustment. After the fixing rod 506 engages with the corresponding fixing groove 507, the counterweight position is locked to prevent slippage, ensuring a stable balance. Through repeated adjustments, the liquid levels in all acrylic tubes 5081 are returned to their original positions, forming a dynamic balance, quickly eliminating imbalance, ensuring the overall stability of the device, and providing a foundation for construction accuracy and safety.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
