Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a cylindrical formwork reinforcement device. Background Technology

[0002] Cylindrical formwork reinforcement devices are crucial tools in building construction used to ensure the stability of cylindrical formwork and prevent deformation during concrete pouring. Currently, the most commonly used reinforcement device is the steel strip reinforcement device, which consists of reinforcing steel strips and reinforcing screws. During installation, the steel strips are first fastened into a complete circle, and then the screws are tightened to secure them to the formwork. Because many steel strips are installed on the cylindrical formwork, they need to be installed individually, resulting in a long construction period and complex procedures. During concrete pouring, the rigidity and strength of the steel strips may be insufficient to withstand significant lateral pressure, easily leading to formwork deformation or bulging; subsequent removal is also quite cumbersome. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a cylindrical template reinforcement device.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a cylindrical template reinforcement device, comprising reinforcement units and support columns. Several reinforcement units are arranged from top to bottom on the outside of the cylindrical template and are connected and fixed by several support columns. Each reinforcement unit includes two C-shaped first and second base plates facing each other. A fixing mechanism is provided between the first and second base plates. The top three sides of the first base plate are respectively provided with fixing seats facing the front, rear, and left sides of the cylindrical template. A first slide is slidably provided on the top of the left fixing seat, and a second slide is slidably provided on the top of the fixing seats on the front and rear sides. A linkage mechanism is provided between the first and second slides. The second slide slides synchronously with the first slide through the linkage mechanism. A power mechanism for driving the first slide to move is provided on the first base plate. A fixing platform is provided on the top of the second base plate facing the right side of the cylindrical template. A connecting rod is provided on the side of the first slide, the second slide, and the fixing platform facing the cylindrical template. An arc-shaped reinforcement plate is provided at the end of the connecting rod.

[0005] Specifically, the fixing mechanism includes vertical plates corresponding to the front and rear sides of the first and second base plates, and several tie bolts are installed between the opposing vertical plates.

[0006] Specifically, the top of the fixed base is provided with a sliding groove, and the bottom of the first and second sliding platforms are provided with sliders, which slide within the corresponding sliding grooves.

[0007] Specifically, the linkage mechanism includes push plates obliquely connected to the front and rear ends of the first slide, and the push plates obliquely pass through the second slide and are slidably connected to the second slide.

[0008] Specifically, the power mechanism includes a connecting seat fixed to the middle of the side of the first base plate away from the second base plate, and a hydraulic cylinder mounted on the top of the connecting seat. The telescopic end of the hydraulic cylinder is fixed to the first slide and drives the first slide to move.

[0009] Specifically, the first slide, the second slide, and the fixed platform are each equipped with a reinforcing rod that connects to the end of the arc-shaped reinforcing plate facing away from the cylindrical template.

[0010] The beneficial effects of this utility model are: the installation and adjustment process of the reinforcement unit is simple and quick. The first slide is moved by the power mechanism, which drives the second slide to slide synchronously. With the pre-positioned second base plate, the complexity of manual operation is greatly reduced and the construction efficiency is improved. By setting several sets of arc-shaped reinforcement plates, it can closely fit the arc surface of the cylindrical template, reducing gaps and loosening caused by shape mismatch. Its load-bearing capacity is better than that of traditional steel strips, and its support stability and durability are high. At the same time, this utility model is easy to disassemble and assemble quickly, which is convenient for the next reuse and shortens the construction cycle. Attached Figure Description

[0014] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0016] like Figures 1-2As shown, a cylindrical formwork reinforcement device includes reinforcement units and support columns 1. Several reinforcement units are arranged from top to bottom on the outside of the cylindrical formwork 2 and connected and fixed by several support columns 1. Each reinforcement unit includes two C-shaped first base plates 3 and 4 facing each other. A fixing mechanism is provided between the first base plates 3 and 4. The fixing mechanism includes vertical plates 11 corresponding to the front and rear sides of the first base plates 3 and 4, and several tie bolts 12 are installed between the opposing vertical plates 11. The number of reinforcement units is determined according to the height of the cylinder and fixed by the support columns 1. After positioning, the bottom first base plate 3 and 2 base plates 4 and the top first base plate 3 and 2 base plates 4 are connected and fixed by tie bolts 12. Whether the remaining reinforcement units need to be fitted with tie bolts 12 depends on the actual situation.

[0017] The top three sides of the first base plate 3 are respectively provided with fixed seats 5, which are directly opposite the front, rear and left sides of the cylindrical template 2. The top of the left fixed seat 5 is provided with a first slide 6, and the top of the fixed seats 5 on the front and rear sides is provided with a second slide 7. The top of the fixed seat 5 is provided with a sliding groove. The bottom of the first slide 6 and the second slide 7 is provided with a slider 13, which slides in the corresponding sliding groove. A linkage mechanism is provided between the first slide 6 and the second slide 7. The second slide 7 slides synchronously with the first slide 6 through the linkage mechanism. The linkage mechanism includes a push plate 14 obliquely connected to the front and rear ends of the first slide 6. The push plate 14 obliquely passes through the second slide 7 and slides in a sliding connection with the second slide 7. The first base plate 3 is provided with a power mechanism to drive the first slide 6 to move. The power mechanism includes a connecting seat 15 fixed to the middle of the side of the first base plate 3 away from the second base plate 4, and a hydraulic cylinder 16 installed on the top of the connecting seat 15. The telescopic end of the hydraulic cylinder 16 is fixed to the first slide 6 and drives the first slide 6 to move.

[0018] The top of the second base plate 4 is provided with a fixed platform 8 directly opposite the right side of the cylindrical template 2. The first slide 6, the second slide 7, and the fixed platform 8 are provided with connecting rods 9 facing the cylindrical template 2. The end of the connecting rod 9 is provided with an arc-shaped reinforcing plate 10. The first slide 6, the second slide 7, and the fixed platform 8 are respectively provided with reinforcing rods 17 connected to the end of the arc-shaped reinforcing plate 10 away from the cylindrical template 2. The arc-shaped reinforcing plate 10, the connecting rod 9, and the reinforcing rod 17 are connected and fixed by bolts, which facilitates the replacement of cylindrical templates 2 of different sizes.

[0019] The design of the first slide 6, the second slide 7, and the linkage mechanism allows for the adaptation to cylindrical templates 2 of different diameters. The first slide 6 and the second slide 7 can be synchronously adjusted according to the actual size of the cylindrical template 2, thereby achieving reinforcement of cylindrical templates of different diameters. The first slide 6, the second slide 7, and the fixed platform 8 are all connected to the arc-shaped reinforcing plate 10 through the connecting rod 9. The arc-shaped reinforcing plate 10 can closely fit the surface of the cylindrical template 2, forming multi-point support, effectively improving the stability and load-bearing capacity of the template, and avoiding problems such as template bulging and template displacement during concrete pouring.

[0020] In operation, the number of reinforcing units and the size of the arc-shaped reinforcing plate 10 are determined according to the height and diameter of the cylindrical template 2. When in use, the device is placed on both sides of the cylindrical template 2, and the first base plate 3 and the second base plate 4 are fixed together using tie bolts 12. Several reinforcing units form a frame structure around the cylindrical template 2. At this time, the arc-shaped reinforcing plate 10 on the second base plate 4 is in close contact with the cylindrical template 2. The hydraulic cylinder 16 is activated, the first slide 6 moves, and the push plate 14 drives the second slide 7 to move. The arc-shaped reinforcing plates 10 on the first slide 6 and the second slide 7 move together toward the cylindrical template 2 until they are in close contact, and the reinforcement of the cylindrical template 2 is completed. After demolding, the tie bolts 12 are removed, and the device is moved to the next cylindrical template 2 to be used.

[0021] The installation and adjustment process of the reinforcement unit of this utility model is simple and quick, without the need for individual installation. The first slide 6 is moved by the power mechanism, which drives the second slide 7 to slide synchronously. Together with the pre-positioned second base plate 4, it greatly reduces the complexity of manual operation and improves construction efficiency. By setting several sets of arc-shaped reinforcement plates 10 for reinforcement, it can closely fit the arc surface of the cylindrical template 2, reducing gaps and loosening caused by shape mismatch. Its load-bearing capacity is better than that of traditional steel strips, and its support stability and durability are high. At the same time, this utility model is easy to disassemble and assemble quickly, which facilitates the next reuse and shortens the construction cycle.
