These structures significantly improve material flow efficiency, reduce material accumulation and cleaning difficulty, thereby enhancing overall operational efficiency. However, the installation, positioning, reinforcement, and removal of the inner curved formwork during the construction of circular cones, especially inverted cones, has long been a technical challenge.

[0027] This invention discloses an adjustable internal support for the inner template of an inverted cone-shaped sedimentation tank. (Refer to...) Figures 1 to 10 An adjustable internal support for the inner template of an inverted conical sedimentation tank mainly includes a fixing mechanism 100, a main shaft mechanism 200, and a support mechanism 300. The main shaft mechanism 200 includes a main rod 210 and a top frame 220. The top frame 220 is fixedly installed in a preset position, and the main rod 210 is fixedly installed at the bottom end of the top frame 220. The main rod 210 extends into the conical sedimentation tank. The fixing mechanism 100 is fixedly installed at the bottom of the sedimentation tank template, and the bottom end of the main rod 210 is fixedly connected to the fixing mechanism 100. Reference Figures 1 to 7 The support mechanism 300 includes multiple angle steels 310 and multiple mounting seats 320. The angle steels 310 include a first plate 311 and a second plate 312. The second plate 312 is fixedly installed on the first plate 311. Multiple connecting holes 313 are opened at both ends of the first plate 311. The second plate 312 has inclined surfaces 314 at both ends. The mounting seats 320 are fixedly connected to the main rod 210. One end of the multiple angle steels 310 is hinged to the mounting seat 320. The angle steels 310 are hinged to the mounting seat 320 by inserting fixing pins 315 into the connecting holes 313. The multiple angle steels 310 are connected to each other by fixing pins 315. One end of the angle steel 310 is fixedly connected to the sedimentation tank template.

[0028] The coordinated action of the fixing mechanism 100, the main shaft mechanism 200, and the support mechanism 300 achieves overall reinforcement of the inverted conical formwork 500. The support mechanism 300 utilizes multiple angle steels 310 connected by fixing pins 315 to form a support surface. This allows for flexible adjustment of the support direction according to the formwork's inclination angle, effectively conforming to the conical inner wall, improving the formwork's positioning accuracy and overall rigidity, preventing displacement or deformation during pouring, and facilitating disassembly and reuse. During initial fixing, the top frame 220 of the support mechanism 300 is fixed to the foundation or fixed platform at both ends. During placement, it is important to ensure that the main rod 210 is coaxial with the axis of the conical formwork for positioning adjustments. Multiple mounting bases 320 are fixedly installed on the main rod 210. The other end of the mounting base 320 is rotatably connected to multiple angle steels 310. According to the requirements of the conical template 500, the multiple angle steels 310 are assembled together to form the corresponding shape. For two adjacent extended and joined angle steels 310, a fixing pin 315 is installed in each of the two connecting holes 313 of the connection part to improve the stability of the connection. An inclined surface 314 is provided on the second plate 312 so that when the two angle steels 310 are installed at an angle, the inclined surface 314 can avoid the plate on the adjacent second plate 312, realizing flexible docking and improving the convenience of installation.

[0029] To improve assembly and disassembly efficiency, when installing angle steel 310, the installation length, position, and angle of each angle steel 310 can be pre-designed based on the inner groove design parameters of the conical template 500 to be supported. Before pre-assembly, the top frame 220 is fixed to the preset points or preset supports. Then, the angle steel 310 is assembled and installed in the factory according to the parameter requirements. The angle steel 310 is assembled and installed on the main rod 210 in one go. Then, the top frame 220 is placed on the transfer vehicle, and the entire device is transported to the template support point. Then, the lower part is positioned. After placement, workers get off the vehicle and proceed to the operating position of the tapered formwork 500 to fix the angle steel 310 that is attached to the tapered formwork 500 to the formwork, achieving rapid assembly and saving a significant amount of assembly time. Furthermore, for tapered formwork 500s of the same specifications, the assembled support device can be quickly transferred to the new tapered formwork 500 position after the angle steel 310 attached to the previous tapered formwork 500 is quickly removed, achieving rapid disassembly and assembly, greatly reducing the time required for disassembly and assembly, improving the quality of construction, and accelerating the construction speed.

[0030] Reference Figures 5 to 7In some embodiments, the mounting base 320 includes a base body 321, a fixing plate 322, and a fixing screw 323. The base body 321 is fixedly connected to the main rod 210. Multiple fixing plates 322 are fixedly installed on the base body 321. The fixing screw 323 passes through multiple fixing plates 322. The fixing plates 322 and the fixing screw 323 are threadedly connected. One end of the angle steel 310 is fixedly connected to the fixing plate 322 through the connecting hole 313 and the fixing screw 323.

[0031] Reference Figure 7 The mounting base 320 adopts a combined structure of base body 321, fixing plate 322, and fixing screw 323, which makes the installation position and angle of angle steel 310 adjustable, enhancing the adaptability and adjustability of the support system. Through the threaded engagement of fixing screw 323 and fixing plate 322, quick locking and fine-tuning of angle steel 310 can be achieved, allowing adjustment of the fixed angle of angle steel 310 or enabling angle steel 310 to be in a rotatable state, improving construction efficiency and support stability.

[0032] Reference Figures 5 to 7 In some embodiments, the main rod 210 is also provided with multiple connecting mechanisms 400. The number of connecting mechanisms 400 can be adjusted according to the diameter of the tapered template 500. At least three connecting mechanisms 400 are used where the diameter is small, and more connecting mechanisms 400 are used where the diameter is large, depending on the required support area of ​​the tapered template 500. Each connecting mechanism 400 includes a connecting frame 410 and a connecting seat 420. The connecting seat 420 is fixedly connected to the main rod 210, one end of the connecting frame 410 is hinged to the connecting seat 420, and the seat body 321 is fixedly installed at the other end of the connecting frame 410.

[0033] The connection mechanism 400 creates a hinged connection between the mounting base 320 and the main rod 210, further enhancing the spatial adaptability of the support mechanism 300. This allows the support direction to be freely adjusted according to the actual tilt angle of the template, better conforming to complex curved surfaces, improving the support effect, and increasing the adaptability of the device.

[0034] Reference Figure 5 In some embodiments, the connecting mechanism 400 further includes a connecting rod 430, and multiple connecting frames 410 are arranged along the axial direction of the main rod 210. One end of each of two adjacent connecting frames 410 is rotatably connected to a connecting rod 430 through a pin 460. The seat 321 is fixedly installed on the end of the connecting rod 430 away from the main rod 210.

[0035] By connecting adjacent connecting frames 410 with connecting rods 430, a stable support frame structure is formed, which can be rhomboid in shape. This enhances the rigidity and load-bearing capacity of the overall support system, preventing local support instability, and is especially suitable for large-span or high-depth inverted conical structures. When rotating the two connecting frames 410, the axial direction of the connecting rods 430 remains parallel to the axial direction of the main rod 210, keeping the vertical position of the seat 321 fixed on the connecting rods 430 unchanged, facilitating the positioning and assembly of the angle steel 310.

[0036] Reference Figure 5 and Figure 6 In some embodiments, the connecting mechanism 400 further includes an arc plate 440, multiple arc plates 440 are fixedly installed along the long rod direction of the connecting rod 430, and multiple seats 321 are fixedly installed along the outer periphery of the arc plate 440.

[0037] The curved plate 440 allows multiple supports 321 to be distributed along the curved trajectory, better conforming to the curvature variation of the inverted conical template 500, improving the uniformity of contact between the support surface and the template, further optimizing the stress distribution, and reducing stress concentration. It also increases the support area, reduces the complexity of the angle steel 310 assembly structure, and further improves the ease of installation of the support device.

[0038] Reference Figure 5 , Figure 6 and Figure 9 In some embodiments, the connecting mechanism 400 further includes a connecting block 450, which is slidably disposed on the angle steel 310. A pin 460 is fixedly installed on the connecting block 450. One end of the angle steel 310 is fixedly connected to the pin 460 through a connecting hole 313. Two adjacent angle steels 310 are connected to the middle angle steel 310 through the connecting block 450.

[0039] The use of connecting block 450 and pin 460 allows two adjacent groups of angle steel 310 support groups to be connected. By adding an additional angle steel 310, both ends of the angle steel 310 are connected to two adjacent connecting blocks 450, so that the adjacent angle steel 310 support groups are connected and supported in the circumferential direction of the main rod 210. This makes the connection between angle steel 310 more flexible and reliable, facilitates quick assembly and adjustment on site, and enhances the cooperative force-bearing capacity between angle steel 310, thereby improving the stability and adaptability of the overall support structure.

[0040] Reference Figures 4 to 8In some embodiments, the main rod 210 includes a mounting rod 211, a mounting plate 212, and a first telescopic cylinder 213. Multiple sets of the main rod 210 are connected sequentially along the axial direction. The mounting plate 212 at the bottom is fixedly connected to the fixing mechanism 100, and the upper end of the mounting plate 212 is fixedly connected to the first telescopic cylinder 213. The mounting rod 211 is fixedly mounted on the telescopic rod of the first telescopic cylinder 213, and the upper end of the mounting rod 211 is fixedly connected to the mounting plate 212. The connecting seat 420 is fixedly mounted on the mounting rod 211.

[0041] The main rod 210 adopts a telescopic structure, and its height is adjusted via the first telescopic cylinder 213. This makes it suitable for construction of inverted conical sedimentation tanks of varying depths, enhancing the versatility and construction flexibility of the device and reducing the need for customized support devices for different projects. Furthermore, if a section of the angle steel 310 is not properly supported or is over-supported, the corresponding first telescopic cylinder 213 is extended or retracted, and adjacent first telescopic cylinders 213 also adjust accordingly, thereby adjusting the axial height of that section of angle steel 310. This achieves overall adjustment of the support position, saving significant adjustment time and improving the overall installation progress.

[0042] Reference Figures 4 to 8 In some embodiments, the main rod 210 also includes guide rods 214, with one end of the multiple guide rods 214 fixedly installed on the bottom end of the first telescopic cylinder 213 and the other end passing through the mounting plate 212.

[0043] The guide rod 214 improves the stability and guiding accuracy of the first telescopic cylinder 213 during the lifting process, prevents the main rod 210 from shifting or shaking during the adjustment process, ensures that the support system is always in a vertical or preset tilt state, and guarantees construction safety and quality.

[0044] Reference Figure 4 In some embodiments, the fixing mechanism 100 includes a plurality of second telescopic cylinders 110, a fixing base 120 and a fixing block 130. Multiple sets of second telescopic cylinders 110 are fixedly installed along the circumference of the fixing base 120, and the fixing block 130 is fixedly installed on the telescopic rod of the second telescopic cylinders 110.

[0045] The fixing mechanism 100 adopts a structure of multiple second telescopic cylinders 110 and fixing blocks 130, which can realize multi-point adjustable fixing of the support system at the bottom of the sedimentation tank, adapt to the bottom structure of different diameters, enhance the bottom anchoring effect, and prevent the support system from floating or shifting during the pouring process.

[0046] Reference Figure 4 In some embodiments, one end of the fixing block 130 is arc-shaped, and an anti-slip layer 140 is fixedly installed on the outer end of the fixing block 130.

[0047] The fixing block 130 adopts an arc-shaped design and is equipped with an anti-slip layer 140, which increases the contact area and friction with the pool bottom template or structure, improves the fixing firmness and anti-slip performance, and further ensures the stability of the support system during the concrete pouring process.

[0048] The implementation principle of the adjustable internal support for the inner template of the inverted cone-shaped sedimentation tank of this invention is as follows: By incorporating a support mechanism 300 and angle steel 310, the device achieves rapid assembly and flexible adjustment, significantly reducing assembly time. In the support mechanism 300, the angle steel 310 achieves angle adjustment and rapid locking through the threaded engagement of the fixing screw 323 and the fixing plate 322. Combined with the connecting block 450, the connection between the angle steels 310 is more reliable, enhancing the overall coordinated load-bearing performance and adaptability. Simultaneously, the overall support height can be adjusted by driving the first telescopic cylinder 213, further improving position adjustment efficiency. This device allows for the rapid removal of local angle steel 310 between tapered templates of the same specification, followed by overall transfer and reuse, achieving rapid disassembly and reusability, significantly improving construction speed, installation accuracy, and project quality.

[0049] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
