Description

Technical Field

[0001] This utility model relates to the field of tie rod technology, specifically to a template tie rod device. Background Technology

[0002] Traditional concrete wall formwork fixing often involves cutting steel bars (such as φ12 or φ16) on-site, passing them through the formwork, and welding positioning shims or steel bars on both sides to form tie rods. This traditional welding process is time-consuming and suffers from difficulties in adjustment and inconsistent quality, easily leading to formwork deformation, bulging, or grout leakage. Furthermore, after the concrete hardens, these steel tie rods often require forceful hammering or gas cutting to remove, which is not only time-consuming and labor-intensive, but also highly destructive, severely impacting the wall's appearance and construction efficiency. Moreover, because they are encased in concrete, they cannot be recycled, resulting in resource waste and hindering green construction and the reuse of formwork.

[0003] Chinese patent application No. 202310642128.7 discloses a basalt fiber construction formwork fixing tie rod and its usage method, including a tie rod and a locking assembly. Both the tie rod and the locking assembly are made of basalt fiber material. The locking assembly includes an inner nut and an outer nut, with the threads on the inner walls of the inner and outer nuts facing opposite directions. The tie rod is threadedly connected to the inner and outer nuts, and a resin encapsulation layer is formed between the inner and outer nuts. This construction formwork fixing tie rod has the following shortcomings: 1) After the pouring construction is completed, the tie rod is embedded in the concrete, which is difficult to remove and cannot be reused, resulting in high construction costs; 2) The template is fixed by pressing it with locking components, but there is no positioning mechanism, which makes it easy to loosen and has poor stability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a template tie rod device that has a simple structure, reduces construction costs, has high tensile strength, and good stability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A template tie rod device includes a threaded tie rod, and an adjusting sleeve, a plug sleeve, an isolation sleeve, and a fixing sleeve, all sleeved on the threaded tie rod. The adjusting sleeve and the fixing sleeve are both threadedly connected to the threaded tie rod. The isolation sleeve is movably sleeved on the threaded tie rod and located between the adjusting sleeve and the fixing sleeve. Two plug sleeves are provided, one plug sleeve located between the adjusting sleeve and the isolation sleeve, and the other plug sleeve located between the fixing sleeve and the isolation sleeve. The outer wall of the adjusting sleeve is provided with a first abutting part for pressing against the template, and the outer wall of the fixing sleeve is provided with a second abutting part for pressing against the template.

[0006] As a further improvement to the above technical solution: One end of the plug sleeve is provided with an abutment end for abutting with the adjusting screw sleeve or the fixing screw sleeve, and the other end is provided with a tapered end for inserting into the end of the isolation sleeve.

[0007] The plug sleeve is a flexible sleeve.

[0008] The first abutting part is annular and located at the outer end of the adjusting screw sleeve.

[0029] Figures 1 to 7 This invention illustrates one embodiment of the template tie rod device. The template tie rod device of this embodiment includes a threaded tie rod 1, and adjusting sleeves 2, plug sleeves 3, isolation sleeves 4, and fixing sleeves 5, all sleeved on the threaded tie rod 1. Adjusting sleeves 2 and fixing sleeves 5 are threadedly connected to the threaded tie rod 1. The isolation sleeve 4 is movably sleeved on the threaded tie rod 1 and located between the adjusting sleeve 2 and the fixing sleeve 5. Two plug sleeves 3 are provided: one plug sleeve 3 is located between the adjusting sleeve 2 and the isolation sleeve 4, and the other plug sleeve 3 is located between the fixing sleeve 5 and the isolation sleeve 4. The outer wall of the adjusting sleeve 2 is provided with a first abutting part 21 for abutting the template, and the outer wall of the fixing sleeve 5 is provided with a second abutting part 51 for abutting the template.

[0030] This template describes one usage process of the tie rod device: For example... Figure 7 As shown, firstly, mark the installation position of the plug sleeve 3 on the threaded tie rod 1; secondly, assemble the threaded tie rod 1, adjusting screw sleeve 2, plug sleeve 3, and isolation sleeve 4 by sequentially fitting the adjusting screw sleeve 2, one plug sleeve 3, isolation sleeve 4, and another plug sleeve 3 onto the threaded tie rod 1 to form an assembly; next, insert the fixing screw sleeve 5 into one side of the template; then, pass the assembly through the template on the other side and thread it onto the fixing screw sleeve 5, so that the plug sleeve 3 fits snugly against the template; finally, rotate the adjusting screw sleeve 2 so that the first clamping part 21 and the second clamping part 51 press against the outside of the two oppositely arranged templates, the isolation sleeve 4 is located between the two templates, one plug sleeve 3 is inserted into one end of the adjusting screw sleeve 2 under the clamping action of the adjusting screw sleeve 2, and the other plug sleeve 3 is inserted into the other end of the adjusting screw sleeve 2 under the clamping action of the fixing screw sleeve 5. After pouring concrete into the template between the two and waiting for the concrete to solidify, unscrew the adjusting screw sleeve 2 and the fixing screw sleeve 5, and then pull out the threaded tie rod 1. In this way, except for the isolation sleeve 4 and the plug sleeve 3, the threaded tie rod 1, the adjusting screw sleeve 2 and the fixing screw sleeve 5 can be reused.

[0031] The template has a tie rod device. On the one hand, the threaded tie rod 1, adjusting screw sleeve 2 and fixing screw sleeve 5 can be reused, reducing construction costs. On the other hand, the first clamping part 21 and the second clamping part 51 are pressed against the outside of the two templates respectively to achieve fixation, resulting in high tensile strength and good stability.

[0032] Furthermore, in this embodiment, one end of the plug sleeve 3 is provided with an abutment end 31 for abutting against the adjusting screw sleeve 2 or the fixing screw sleeve 5, and the other end is provided with a tapered end 32 for inserting into the end of the isolation sleeve 4.

[0033] Furthermore, in this embodiment, the plug sleeve 3 is a flexible sleeve, such as a rubber sleeve or a silicone sleeve, which is easy to compress, expand, and seal.

[0034] Furthermore, such as Figure 1 and Figure 3 As shown, in this embodiment, the first abutting part 21 is annular and located at the outer end of the adjusting screw sleeve 2. The annular first abutting part 21 abuts against the template, thereby improving the abutting effect.

[0035] Furthermore, in this embodiment, the adjusting screw sleeve 2 is provided with a first screwing part 22 on the outside of the first tightening part 21, which facilitates rotating and screwing the adjusting screw sleeve 2.

[0036] Furthermore, in this embodiment, the first abutting part 21 is provided with a first locking member 6 for locking onto the template. Thus, after the first abutting part 21 abuts against the template and is in place, it can be locked onto the template by the first locking member 6, preventing loosening and improving stability. Preferably, the first locking member 6 is a plurality of rotating handles arranged at intervals around the outer circumference of the adjusting screw sleeve 2.

[0037] Furthermore, the first locking element 6 is a locking screw. The template has a locking hole 91 (e.g., [missing information]) at the position corresponding to the first locking element 6 for inserting the locking screw. Figure 8 (As shown). After the locking screw is inserted into the lock hole 91, it prevents the adjusting sleeve 2 from rotating.

[0038] Furthermore, such as Figure 1 and Figure 4 As shown, in this embodiment, the second abutting part 51 is annular and located at the outer end of the fixing screw sleeve 5. The annular second abutting part 51 abuts against the template, improving the abutting effect.

[0039] Furthermore, such as Figure 4 As shown, in this embodiment, the fixing screw sleeve 5 has a second tightening part 52 on the outside of the second abutting part 51, which facilitates rotating and tightening the fixing screw sleeve 5. Preferably, the second abutting part 51 is an extension part that extends outward from the outer periphery of the fixing screw sleeve 5.

[0040] Furthermore, in this embodiment, the second abutting part 51 is provided with a second locking member 7 for locking onto the template. In this way, after the second abutting part 51 abuts against the template and is in place, it can be locked onto the template by the second locking member 7 to prevent loosening and improve stability.

[0041] Furthermore, the second locking element 7 is also a locking screw. A locking hole 91 for inserting the locking screw is also provided at the position corresponding to the second locking element 7 on the template. After the locking screw is inserted into the locking hole 91, it prevents the fixing sleeve 5 from rotating.

[0042] Furthermore, such as Figure 1 and Figure 4As shown, in this embodiment, the outer end of the fixing sleeve 5 is provided with a plugging component 8. The fixing sleeve 5 is located at one end of the threaded tie rod 1, and the other end of the threaded tie rod 1 is fixed with a rotating component 11. The plugging component 8 at the outer end of the fixing sleeve 5 can prevent the threaded tie rod 1 from passing through the outer end of the fixing sleeve 5, thus preventing the threaded tie rod 1 from being over-tightened. Of course, the plugging component 8 is preferably detachable from the fixing sleeve 5 and can be used selectively. Preferably, the plugging component 8 is a locking pin.

[0043] It should be noted that the outer end mentioned in this application is the end away from the isolation sleeve 4.

[0044] Specifically, such as Figure 8 As shown, the template is provided with through holes 9. When in use, the inner ends of the adjusting screw sleeve 2 and the fixing screw sleeve 5 are respectively inserted into the corresponding through holes 9.

[0045] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
