Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a reusable through-rod for concrete formwork in building walls. Background Technology

[0002] In building wall construction, tie rods are used for quick and accurate installation and disassembly. They fix the formwork to the wall surface through the tie action, preventing the formwork from shifting or collapsing during the pouring process. They are an important tool in building wall construction.

[0003] Patent CN221502720U discloses a reusable through-rod for concrete formwork in building walls. It includes a fixing component and an adjusting component. In application, a first mounting shaft causes a ring to rotate, which in turn rotates an adjusting rod, causing it to move outwards. The rod is then adjusted according to the distance between the mold plates. After adjustment, a sleeve is installed on the outside of the rod within the mold area. A second mounting shaft then causes a gear to rotate and move until the second mounting plate is pressed tightly against the mold plate, at which point rotation stops. Concrete is then added to the mold, and the first and second mounting plates stabilize the mold plate. After the concrete solidifies, the gear rotates to pull the rod out through one end of a second threaded rod. Finally, the adjusting rod pulls out the alignment rod. However, the sleeve of the reusable through-rod for concrete formwork in the building wall, although it is slidably connected to the formwork plate, has a fixed length. For walls of different widths, the sleeve may be too short or too long. If the sleeve is too short, it will not be able to tie smoothly, and if the sleeve is too long, it will protrude and obstruct the adjustment of the fixing and adjusting components, thus limiting its use.

[0056] Specifically, the adjustment unit 3 includes an adjustment sleeve 31 and an adjustment boss 32. The inner diameter of the adjustment sleeve 31 is equal to the outer diameter of the first connecting section 13, and the outer diameter of the adjustment sleeve 31 is equal to the outer diameter of the first sleeve 12. The outer diameter of the adjustment boss 32 is equal to the inner diameter of the second connecting section 23, and the inner diameter of the adjustment boss 32 is equal to the inner diameter of the second sleeve 22.

[0057] Furthermore, the inner diameters of the first sleeve 12, the second sleeve 22, and the adjusting boss 32 are the same; the outer diameters of the first sleeve 12, the second sleeve 22, and the adjusting sleeve 32 are the same. When using one adjusting unit 3 to form an adjustable sleeve, the adjusting sleeve 31 is connected to the first connecting section 13 of the first end 1, and the adjusting boss 32 is connected to the second connecting section 23 of the second end 2, forming a complete sleeve. When using two adjusting units 3 to form an adjustable sleeve, the first connecting section 13 of the first end 1 is embedded in the adjusting sleeve 31 of the first adjusting unit 3, the adjusting boss 32 of the first adjusting unit 3 extends into the adjusting sleeve 31 of the second adjusting unit 3, and the adjusting boss 32 of the second adjusting unit 3 extends into the second connecting section 23 of the second end 2, thus forming another complete sleeve. Similarly, an appropriate number of adjusting units 3 can be selected according to the wall thickness and assembled together with the first end 1 and the second end 2 to form an adjustable sleeve adapted to the wall width.

[0058] In this embodiment, the first mounting plate 7 and the second mounting plate 8 are both annular plate structures; the first mounting plate 7 is placed on the outside of the first baffle 11, and the first mounting plate 7 is provided with a third protrusion 71 that matches the first groove 15; the second mounting plate 8 is placed on the outside of the second baffle 21, and the second mounting plate 8 is provided with a fourth protrusion 81 that matches the second groove 25.

[0059] Specifically, such as Figures 1-5 as well as Figures 10-11As shown, in the tie rod assembly, the outer sleeve assembly 4 includes a threaded sleeve with threads on its outer wall, a first platform 41 at its outer end, and a first through hole 42. The inner rod assembly 5 is a screw adapted to the threaded sleeve, with a second platform 51 at its outer end and a second through hole 52. When turning the outer sleeve assembly 4 or the inner rod assembly 5, pipe wrenches can be used to clamp the first platform 41 or the second platform 51, or a steel bar segment or iron rod can be passed through the first through hole 42 or the second through hole 52, and the rotation of the steel bar segment or iron rod can be used to adjust the rotation of the outer sleeve assembly 4 or the inner rod assembly 5, ultimately achieving the length adjustment of the tie rod assembly. The threaded sleeve passes sequentially through the first mounting plate 7 and the first end 1, and is secured with a nut 9 at its outer end; the screw passes sequentially through the second mounting plate 8 and the second end 2, and is secured with a nut 9 at its outer end. Furthermore, a plug 10 is provided at the outer end of the threaded sleeve to prevent concrete from entering the interior of the threaded sleeve. The plug body 10 has a cylindrical structure, and its outer diameter is adapted to the inner diameter of the threaded sleeve. A pull ring 101 is also fixed to the outer end of the plug body 10 to facilitate pulling out the plug body 10.

[0060] The reusable through-rod for concrete formwork in building walls provided in this embodiment is used by first abutting the first end 1 and the second end 2 against the mold plates 6 on both sides. Correspondingly, grooves 61 adapted to the first protrusion 14 and the second protrusion 24 are provided on the mold plates 6, but the grooves 61 do not penetrate the mold plate 6 itself. The mold plates are engaged by the first protrusion 14 and the second protrusion 24 being embedded in the corresponding grooves, ensuring a tight fit between the sleeve and the mold plate. At the same time, the mold plate 6 is also provided with circular holes 62 adapted to the first end and the second end. In this embodiment, the first baffle 11 of the first end 1 is provided with two first protrusions 14 located on the same diameter and four centrally symmetrical first grooves 15; the second baffle of the first end 2 is also provided with two second protrusions 24 located on the same diameter and four centrally symmetrical second grooves 25.

[0061] Based on the actual width of the wall, the length of the sleeve is flexibly adjusted to adapt to the wall width by cooperating with the adjusting sleeve 31 in the adjusting unit 3 with the first connecting section 13, the adjusting boss 32 with the second connecting section 23, and by adjusting the number of adjusting units. Then, the threaded sleeve of the tie rod assembly is passed sequentially through the first mounting plate 7 and the first end 1, and tightened with a nut; the screw is passed sequentially through the second mounting plate 8 and the second end 2, and tightened with a nut as well, completing the connection between the tie rod assembly and the sleeve. During concrete pouring, the tie rod assembly and the sleeve fix the formwork through a tying action, preventing formwork displacement or collapse. After the concrete has solidified, the nuts are loosened, the tie rod assembly is disassembled, and the formwork can be removed and the tie rod reused.

[0062] The first end 1 and the second end 2 are respectively abutted against the two sides of the mold plate 6, and the mold plate 6 is engaged by the first protrusion 14 and the second protrusion 24 to ensure a tight fit between the sleeve and the mold plate. The length of the sleeve is adjusted according to the width of the wall. The sleeve length can be flexibly adjusted by adjusting the fit between the sleeve 31 and the first connecting section 13, the adjusting boss 32 and the second connecting section 23, or by adjusting the number of adjusting units. The threaded sleeve and screw of the tie rod assembly are passed through the first end 1 and the second end 2 respectively, and tightened by the nut 9 to ensure a stable connection between the tie rod assembly and the sleeve. Concrete is poured into the mold. The tie rod assembly and the sleeve pull together to prevent the formwork from shifting or collapsing. After the concrete has solidified, the tie rod assembly can be disassembled by loosening the nut for reuse.

[0063] The reusable through-rod tie rod for concrete formwork in building walls provided in this embodiment features an adjustable sleeve design, allowing for flexible sleeve length adjustment to adapt to different wall widths. This overcomes the limitations of fixed sleeve lengths in existing technologies, offering strong adaptability. Each end of the sleeve is equipped with a corresponding baffle and mounting plate. The interlocking design of matching protrusions and grooves enhances the connection stability between the sleeve and the formwork plate 6, as well as the mounting plates. Simultaneously, the tie rod assembly, connected by a threaded sleeve and screw, further improves the overall structural stability, ensuring the formwork's stability during concrete pouring.

[0064] Through the flexible design of the adjustable sleeve and tie rod assembly, construction workers can quickly adjust the length of the tie rod according to the width of the wall, reducing the time required for replacement or adjustment due to unsuitable sleeve length and significantly improving construction efficiency. In this embodiment, the tie rod assembly adopts an adjustable design, and after the concrete has solidified, it can be disassembled by simply loosening the nut, facilitating reuse and reducing construction costs.

[0065] The reusable through-rod tie rod for concrete formwork in building walls provided in this embodiment overcomes the shortcomings of the prior art through the adjustable design of the adjustable sleeve and tie rod assembly, significantly improving the adaptability, stability and construction efficiency of the through-rod tie rod for concrete formwork in building walls, and has significant practicality and strong applicability.
