DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clearly understood, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0033] Please refer to Figure 1 and Figure 2, a description of the arc-shaped shaping template provided by the present utility model will be given. The arc-shaped shaping template includes a plurality of templates 1 that are spliced together to form an annular structure, a steel wire rope 2 wound around the outside of the plurality of templates 1, a plurality of clamping blocks 21, and two connecting members 3. Among them, the plurality of clamping blocks 21 are arranged on the steel wire rope 2 at intervals along the length direction of the steel wire rope 2. The two connecting members 3 are both arranged on the outer side surface of the template 1, and the two connecting members 3 are connected by a fastening member 4. The two connecting members 3 are used to connect any two of the clamping blocks 21 respectively, so that the part of the steel wire rope 2 between the two clamping blocks 21 fixes the annular structure.

[0034] It should be understood that in actual application, the number of the templates 1, the steel wire rope 2, and the connecting members 3 can be set according to needs. Exemplarily, in order to reduce the number of seams after the templates 1 are spliced, the number of the templates 1 is two. The number of the steel wire ropes 2 is selected according to the height of the template 1. When the height of the template 1 is relatively high, a plurality of steel wire ropes 2 are arranged from top to bottom in sequence, so as to ensure the fixing effect on the template 1. Both ends of each steel wire rope 2 are provided with connecting members 3 for connecting the steel wire rope 2.

[0035] After the two templates 1 are spliced together to form a complete annular structure, the steel wire rope 2 is wound around the outside of the template 1, providing a uniform binding force for the template 1 and preventing the template 1 from deforming or bulging during processes such as pouring.

[0036] Please refer to Figure 3 and Figure 4 , the connecting member 3 further includes a ferrule 31. The ferrule 31 is hinged to the connecting member 3, and there is a locking assembly between the ferrule 31 and the connecting member 3. Among them, when the locking assembly connects the ferrule 31 and the connecting member 3, the ferrule 31 is buckled on the connecting member 3, and the ferrule 31 is also adapted to be connected to any one of the clamping blocks 21.

[0037] Specifically, please refer to Figure 3 and Figure 4 , the clamping blocks 21 are distributed at both ends of the steel wire rope 2. A notch for the steel wire rope 2 to pass through is formed on the ferrule 31. When the ferrule 31 is buckled on the connecting member 3, the clamping block 21 will be stuck in the ferrule 31, and the steel wire rope 2 passes through the notch.

[0038] When it is necessary to adjust the length of the steel wire rope 2, the ferrule 31 is used to connect with the clamping block 21 at the corresponding position, so that the length of the steel wire rope 2 between the two connecting members 3 is adapted to the circumferential length after the templates 1 are spliced. The locking assembly can fix the position of the ferrule 31, so that a firm connection is maintained between the steel wire rope 2 and the connecting member 3. After the steel wire rope 2 is wound around the template 1, by using the fastening member 4 to fixedly connect the two connecting members 3, the fastening of the template 1 can be realized.

[0039] In some embodiments, please refer to Figure 3 andFigure 4 The locking component includes a first fitting portion 51, a second fitting portion 52, and a locking portion 53. Among them, the first fitting portion 51 is fixedly arranged on the ferrule 31. The second fitting portion 52 is fixedly arranged on the connecting member 3. A threaded hole is provided on the locking portion 53. External threads are provided on both the first fitting portion 51 and the second fitting portion 52. When the ferrule 31 is buckled on the connecting member 3, the first fitting portion 51 and the second fitting portion 52 are combined into a cylindrical structure, so that the locking portion 53 is threadedly connected to both the first fitting portion 51 and the second fitting portion 52 at the same time.

[0040] Specifically, please refer to Figure 4 , the first fitting portion 51 is located on the side of the ferrule 31 away from the hinge axis. Both the first fitting portion 51 and the second fitting portion 52 are semi-cylindrical structures. The external threads are provided on the arc surfaces of the first fitting portion 51 and the second fitting portion 52 facing away from the fitting surface, so that the outer peripheral wall of the cylindrical structure forms an external thread structure suitable for being threadedly connected to the locking portion 53.

[0041] The locking portion 53 fixes the first fitting portion 51 and the second fitting portion 52 together through threaded connection, thereby firmly fixing the ferrule 31 on the connecting member 3, ensuring that the clamping block 21 will not come out of the ferrule 31, so that the steel wire rope 2 will not loosen when subjected to tension, and ensuring the stability of the template 1 during use.

[0042] In some embodiments, please refer to Figure 4 , a connecting rod 511 is coaxially and fixedly arranged on the first fitting portion 51. The outer diameter of the connecting rod 511 is smaller than the inner diameter of the locking portion 53, so that the locking portion 53 can slide and sleeved on the connecting rod 511, and one end of the connecting rod 511 facing away from the first fitting portion 51 has a stop block 512 for abutting against the locking portion 53.

[0043] When it is necessary to open the ferrule 31, rotate the locking portion 53 so that the locking portion 53 disengages from the first fitting portion 51 and the second fitting portion 52 and sleeved on the connecting rod 511. Under the blocking action of the stop block 512, the locking portion 53 cannot come out of the connecting rod 511, thus avoiding the loss of the locking portion 53 when not in use.

[0044] In some embodiments, please refer to Figure 4 , a card slot 311 matching the clamping block 21 is provided on the inner wall of the ferrule 31. When the ferrule 31 is buckled on the connecting member 3, the clamping block 21 is adapted to be clamped in the card slot 311. Through the card slot 311, the tightness of the connection between the clamping block 21 and the ferrule 31 can be improved, so that the connection between the ferrule 31 and the clamping block 21 is more stable, and during use, the clamping block 21 is not easily disengaged from the ferrule 31.

[0045] In some embodiments, please refer to Figure 4, on one side of the ferrule 31 away from the hinge axis, a plug 312 is fixedly arranged, and a slot 313 matching the plug 312 is formed on the connecting piece 3. When the ferrule 31 is buckled on the connecting piece 3, the plug 312 is inserted into the slot 313, thereby enhancing the connection strength between the ferrule 31 and the connecting piece 3, preventing the ferrule 31 from shaking and slipping and deforming during use, and improving the reliability of the ferrule 31 during use.

[0046] In some embodiments, please refer to Figure 3 , a hanging ring 63 is fixedly arranged on one of the connecting pieces 3. A hook 62 adapted to be hung in the hanging ring 63 is fixedly arranged on the other connecting piece 3, and the hook 62 is connected to the connecting piece 3 through an elastic member 61. During use, when the hook 62 is hung on the hanging ring 63, the two connecting pieces 3 can be pulled closer to each other, playing an auxiliary fixing role for the steel wire rope 2, making it more convenient to operate when subsequently fixing the two connecting pieces 3 with the fastener 4.

[0047] As an alternative embodiment, the elastic member 61 can be an elastic object such as an elastic rope or a spring, and when the hook 62 is hung on the hanging ring 63, it can provide a pulling force to the two connecting pieces 3, making the two connecting pieces 3 approach each other.

[0048] Exemplarily, the elastic member 61 is an elastic rope, one end of the elastic rope is fixedly connected to the connecting piece 3, and the other end of the elastic rope is fixedly connected to the hook 62.

[0049] In some embodiments, please refer to Figure 1 and Figure 2 , a positioning rib plate 7 is fixedly arranged on the template 1, and the positioning rib plate 7 abuts against the lower side of the steel wire rope 2. The positioning rib plate 7 can position the steel wire rope 2 to prevent it from sliding on the template 1.

[0050] When winding the steel wire rope 2, place the steel wire rope 2 above the positioning rib plate 7 so that the positioning rib plate 7 abuts against the lower side of the steel wire rope 2. The positioning rib plate 7 can play a role in supporting and positioning the steel wire rope 2, so that the steel wire rope 2 will not be skewed or displaced due to sagging, facilitating the operation and fixing of the steel wire rope 2.

[0051] During the concrete pouring process, the steel wire rope 2 may be displaced due to the pressure of the concrete. The presence of the positioning rib plate 7 can effectively limit the movement of the steel wire rope 2, ensuring that the steel wire rope 2 always remains in the correct position, thereby ensuring the stability of the template 1.

[0052] In some embodiments, please refer to Figure 1 and Figure 2, the positioning rib plate 7 extends along the circumferential direction of the formwork 1. The positioning rib plate 7 can provide additional support for the formwork 1, thereby enhancing the structural strength of the formwork 1 and preventing the formwork 1 from deforming under the pressure of concrete.

[0053] In some embodiments, refer to Figure 3 , the fastener 4 includes a bolt 41 and a nut 42 connected by threads. Among them, the bolt 41 passes through two connecting members 3 and is threadedly connected to the nut 42, so that the head of the bolt 41 and the nut 42 respectively abut against both sides of the two connecting members 3. Specifically, a through hole for the bolt 41 to pass through is formed in the connecting member 3. When fixing the two connecting members 3, the bolt 41 is passed through the through hole, and then the nut 42 is screwed onto the bolt 41 to make the two connecting members 3 approach each other, and the steel wire rope 2 tightly fixes the formwork 1 together. The connection method of the bolt 41 and the nut 42 has high strength and reliability, can withstand a large tensile force, and ensures that the connecting members 3 at both ends of the steel wire rope 2 will not separate. At the same time, the bolt 41 and the nut 42 are convenient to disassemble and assemble and can be reused.

[0054] In some embodiments, refer to Figure 3 , a flange 11 is fixedly arranged at one end of the formwork 1, and a groove 12 is formed at the other end of the formwork 1. When adjacent formworks 1 are spliced, the flange 11 and the groove 12 are engaged with each other. Specifically, the flange 11 extends along the height direction of the formwork 1, and the groove 12 extends along the height direction of the formwork 1.

[0055] Through the engagement between the flange 11 and the groove 12, the connection between the formworks 1 is made tighter, and it is not easy to leak slurry. The cooperation between the flange 11 and the groove 12 has a certain positioning effect, which can ensure the regular overall shape of the formwork 1. During the concrete pouring process, even under the lateral pressure of the concrete, the adjacent formworks 1 can maintain the stability of the shape and will not be misaligned or deformed with each other, thus ensuring the dimensional accuracy of the cast circular arc structure.

[0056] When installing the formwork 1, align the flange 11 of one formwork 1 with the groove 12 of another formwork 1, and gently push to make them engage with each other, then multiple formworks 1 can be spliced in sequence to form a complete ring. The splicing method is simple and fast, without the need for complex tools and operations.

[0057] In summary, compared with the prior art, for the arc-shaped shaping template provided by the present utility model, when the length of the steel wire rope 2 needs to be adjusted, the ferrule 31 is connected to the corresponding block 21, so that the length of the steel wire rope 2 between the two connecting members 3 is adapted to the circumference after the templates 1 are spliced. The locking assembly can fix the position of the ferrule 31, so that a firm connection is maintained between the steel wire rope 2 and the connecting member 3. After the steel wire rope 2 is wound around the template 1, the two connecting members 3 are fixedly connected by using the fastener 4, and thus the fastening of the template 1 can be realized.

[0058] The foregoing are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
