Abstract
Description
Technical Field
[0001] This utility model relates to the field of corner column technology, specifically a tie rod wire twisting machine for construction. Background Technology
[0002] Basket-type cantilever tie rods are load-bearing components used in building structures. They achieve stable support for cantilever beams or structures through prestressing technology and are commonly found in curtain wall construction, external scaffolding, and large-span floor slab support. They are particularly suitable for projects with limited space or requiring high load-bearing capacity. Due to their efficient force transmission, flexible adaptability, and economy, basket-type cantilever tie rods have become a key component of modern architecture.
[0003] like Figure 1 The diagram shows the structure of a common basket-type cantilever tie rod. The tie rod 9 includes a sleeve 91 with turnbuckle nuts at both ends. Each turnbuckle nut connects to a threaded rod 92, and the end of the threaded rod 92 furthest from the sleeve 91 is connected to an adapter plate 93. During use, the overall length of the tie rod 9 is adjusted by rotating the threaded rod 92 to accommodate different construction needs. However, during use on construction sites, concrete often falls onto the tie rod 9, including at the connection between the threaded rod 92 and the sleeve 91. This concrete hardens quickly, becoming fixed to the tie rod 9 and affecting the rotation of the threaded rod relative to the sleeve. Current methods involve manually tapping the tie rod 9 or manually rotating the threaded rod with a pry bar to remove the concrete. However, both methods require significant manual labor, and due to the length of the tie rod 9, manually removing the concrete is difficult and poses safety hazards. Utility Model Content
[0004] The purpose of this utility model is to provide a tie rod stranding machine for construction to solve the problems mentioned in the background art.

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.
[0022] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0023] In this application, the tie rod threading machine is used for threading the basket-type cantilevered tie rod. The tie rod threading machine can drive the adapter plate 93 of the tie rod 9 to rotate, and the adapter plate 93 drives the threaded rod 92 to rotate. The sleeve 91 of the tie rod 9 is restricted to not rotate by the tie rod threading machine. Therefore, the threaded rod 92 can rotate relative to the sleeve 91 to achieve the purpose of threading and removing concrete. That is, it can squeeze out and remove the concrete solidified at the threaded joint of the threaded rod 92 and the sleeve 91, including the concrete solidified inside the threads of the sleeve 91 and the threaded rod 92. This ensures that the threaded rod 92 can rotate and adjust relative to the sleeve 91, which is convenient for the next use of the tie rod 9 as well as for its recovery, storage or transportation.
[0024] Please refer to Figure 2-6 As shown, this application discloses a construction tie rod stranding machine, which includes a frame 1, a bracket 11, a drive device 2 for rotation at one end of the bracket 11, a connecting shaft 3 mounted above the end of the bracket 11 near the drive device 2, the connecting shaft 3 being rotatably connected to the drive device 2, a positioning component 4 at the end of the connecting shaft 3 away from the drive device 2, and an anti-rotation rod 15 on each side above the bracket 11 along the axial direction of the connecting shaft 3, each anti-rotation rod 15 forming an insertion hole with the bracket 11, and at least one limiting rod 7 connected to the two insertion holes formed between the two anti-rotation rods 15 and the bracket 11.
[0025] In this application, the components are installed via the bracket 11 of the frame 1. The drive device 2 drives the connecting shaft 3 to rotate, which in turn drives the positioning component 4 connected to it to rotate synchronously. The connecting shaft 3 is mounted on the bracket 11 for easy rotation. The positioning component 4 is used for positioning the tie rod 9. By rotating the positioning component 4, the threaded rod 92 of the tie rod 9 rotates synchronously, while the sleeve 91 of the tie rod 9 does not rotate relative to the frame 1. The rotation of the sleeve 91 is restricted by the limiting rod 7 inserted into the sleeve 91 to prevent it from rotating. Therefore, the threaded rod 92 can rotate relative to the sleeve 91, that is, the threaded rod 92 can perform a twisting action relative to the sleeve 91. This allows the concrete to be squeezed out and removed from the threads of the sleeve 91, the threads of the threaded rod 92, and the joint between the sleeve 91 and the threaded rod 92. This removes the concrete from the tie rod 9, preventing it from affecting the next use of the tie rod 9 and the recycling, storage, and transportation of the tie rod 9. In actual use, after extruding concrete, lubricating oil can be applied to the threads of sleeve 91 and threaded rod 92 to prevent the tie rod 9 from rusting, reduce friction, prevent the threads from jamming, and achieve the purpose of protecting the tie rod 9.
[0026] The anti-rotation rod 15 works in conjunction with the limiting rod 7 to prevent the sleeve 91 of the tie rod 9 from rotating synchronously with the threaded rod 92, thereby achieving the purpose of wire stranding to remove concrete. By inserting the limiting rod 7 into the insertion hole formed by the anti-rotation rod 15 and the bracket 11, the rotation of the limiting rod 7 is limited, thus limiting the rotation of the sleeve 91 of the tie rod 9. The insertion hole is rectangular, allowing the limiting rod 7 to move horizontally within it, ensuring that the sleeve 91 of the tie rod 9 can move horizontally during wire stranding. It also accommodates wire stranding to remove concrete from tie rods of different lengths. Two anti-rotation rods 15 are located on the front and rear sides of the bracket 11, each forming an insertion hole with the bracket 11, thus limiting the rotation of the limiting rod 7 through these two insertion holes.
[0027] like Figure 4 As shown, in one embodiment of this application, the positioning component 4 includes a connecting pipe 41, which is sleeved on the connecting shaft 3. The connecting pipe 41 is connected to a positioning block 42, and the positioning block 42 is provided with a positioning groove 421 for inserting the adapter plate 93. Several baffles 43 are provided above the positioning groove 421.
[0028] In this design, the connecting pipe 41 is used to connect with the connecting shaft 3. The connection between the connecting pipe 41 and the connecting shaft 3 is achieved by sleeved onto the connecting shaft 3. The connecting shaft 3 and the connecting pipe 41 can be connected by screws, snap-fits, or welding, or by external components such as bolts or pins. The positioning block 42 is used to install and position the adapter plate 93 of the connecting rod 9, ensuring the accurate installation position of the connecting rod 9. This is achieved by directly inserting the adapter plate 93 into the positioning groove 421 of the positioning block 42. The baffle 43 is used to limit the rotation of the adapter plate 93 installed in the positioning groove 421, preventing the adapter plate 93 from rotating within the positioning groove 421. In this application, the adapter plate 93 of the pull rod 9 is inserted into the positioning groove 421. The positioning groove 421 is a rectangular groove, and the adapter plate 93 is a V-shaped plate. The adapter plate 93 will not rotate relative to the positioning groove 421, and the friction between the adapter plate 93 and the positioning block 42 can prevent the adapter plate 93 from coming off the positioning block 42 during the wire twisting process.
[0029] Based on the above scheme, preferably, the connecting pipe 41 is provided with a plurality of fixing holes 411, which are either smooth holes or threaded holes. The fixing holes 411 facilitate the connection of bolts or pins, enabling quick connection between the connecting pipe 41 and the connecting shaft 3. When the fixing hole 411 is a smooth hole, a pin hole or threaded hole can be provided at the corresponding position on the connecting shaft 3, and a bolt or pin can be used to connect and fix the connecting pipe 41 and the connecting shaft 3. When the fixing hole 411 is a threaded hole, a screw can be screwed in to abut against the connecting shaft 3, achieving connection between the connecting shaft 3 and the connecting pipe 41.
[0030] like Figure 5As shown, in one embodiment of this application, one end of the bracket 11 is connected to a mounting platform 12 for mounting the drive device 2, a storage disk 13 is provided above the bracket 11, two anti-rotation rods 15 are mounted on the bracket 11 and symmetrically arranged on both sides of the storage disk 13, and two support plates 16 for mounting the connecting shaft 3 are provided above the end of the bracket 11 near the mounting platform 12.
[0031] In this design, the drive unit 2 is installed on the mounting platform 12, and the storage tray 13 is used to collect the concrete squeezed out during the wire twisting operation, facilitating the collection and disposal of the fallen concrete and preventing concrete pollution. Anti-rotation rods 15 are located on both sides of the storage tray 13, facilitating the installation of the anti-rotation rods 15 and the storage tray 13, and allowing the tie rod 9 to be mounted above the storage tray 13, so that the concrete twisted out on the tie rod 9 can fall into the storage tray 13. Support plates 16 are used to support the installation of the connecting shaft 3, and the two support plates 16 ensure the stable installation of the connecting shaft 3.
[0032] Based on the above scheme, preferably, the bottom of the storage pan 13 gradually curves downwards from the edge towards the center, and a through hole is provided in the center of the bottom of the storage pan 13, connected to a waste discharge pipe 14. This structural design of the storage pan 13 allows concrete falling into it to concentrate towards the center, facilitating its collection. The waste discharge pipe 14 facilitates the discharge of fine concrete particles extruded from the storage pan 13, making collection and cleaning convenient. Simultaneously, it also allows wastewater from rinsing the storage pan 13 with water to be discharged through the waste discharge pipe 14.
[0033] Based on the above scheme, preferably, both support plates 16 are provided with stepped mounting holes 161, and bearings 9 that rotate with the connecting shaft 3 are installed in the mounting holes 161. The mounting holes 161 are used for mounting the bearings 9, and the bearings 9 ensure smooth rotation of the connecting shaft 3. The mounting holes 161 have a stepped structure, which is used to limit one side of the bearings 9 and prevent the connecting shaft 3 from becoming unstable due to the shaking of the bearings 9.
[0034] Based on the above scheme, preferably, the mounting platform 12 is provided with several oblong holes 17 for mounting the drive device 2. Both the bracket 11 and the mounting platform 12 are made of U-shaped metal plates, and the drive device 2 includes a geared motor. The oblong holes 17 facilitate the installation and position adjustment of the drive device 2, ensuring rapid installation. The U-shaped plates used for the bracket 11 and mounting platform 12 reduce the weight of the frame 1 while maintaining overall structural strength; furthermore, the U-shaped plates effectively reduce material requirements, lowering the manufacturing cost of the wire twisting machine. The drive device 2 is preferably a geared motor, which provides high torque output and a slow rotation speed, meeting the wire twisting requirements and preventing damage to the drive device 2, connecting shaft 3, positioning assembly 4, or tie rod 9 due to excessive rotation speed. Simultaneously, the geared motor meets heavy-load requirements, satisfying the force demands of concrete extrusion.
[0035] Based on the above scheme, the drive device 2 is connected to a drive gear 5, and the end of the connecting shaft 3 away from the positioning component 4 is provided with a driven gear 6. The drive gear 5 and the driven gear 6 are connected. That is, the rotation output end of the drive device 2 is connected to the drive gear 5. For example, the output shaft of the geared motor is connected to the drive gear 5, which can drive the drive gear 5 to rotate. The drive gear 5 drives the driven gear 6 to rotate through the chain, and the driven gear 6 drives the connecting shaft 3 to rotate. Finally, the positioning component 4 and the threaded rod 92 are driven to rotate. The threaded rod 92 rotates relative to the sleeve 91, realizing the twisting of the threaded rod 92 with the sleeve 91, and extruding the concrete into the threads of the threaded rod 92 and the sleeve 91.
