Description

Technical Field

[0001] This utility model belongs to the field of steel cage binding, specifically a steel cage binding device for anti-slide pile holes. Background Technology

[0002] Reinforcing cages are installed inside the pile holes of anti-slide piles, primarily serving a tensile strength function. While concrete has high compressive strength, its tensile strength is very low; the reinforcing cages restrain the concrete within the pile body, enabling it to withstand a certain axial tensile force. During the construction of bridges, culverts, or high-rise buildings, foundation piling may be required. This is done using machine-drilled holes and water-jet drills to achieve the designed depth, then lowering the reinforcing cage into the pile hole, followed by the insertion of a guide pipe for concrete pouring. Therefore, the binding of the reinforcing cage is a necessary step in the construction of anti-slide piles. However, due to the large volume of the reinforcing cage and the long distance from top to bottom, it is necessary to prevent displacement between the reinforcing bars during the binding process, which usually requires auxiliary tools.

[0003] Utility model patent application CN202020393808.1 discloses a rebar cage binding device, which includes a main body. A second steel channel is provided on the left side of the main body. A square interface groove is provided at the upper end of the side of the second steel channel. A first trapezoidal interface groove is provided at the lower end of the square interface groove. A second trapezoidal interface groove is provided at the bottom end of the second steel channel. In this utility model, five steel channels of different lengths are assembled at certain positions and connected by welding, so that the main body has a stable frame that can bear the weight of the rebar cage. At the same time, it can also effectively assist in the fabrication of the rebar cage, speed up the fabrication process, and improve the production efficiency of the factory. A diagonal support is provided at the lower right end of the connection between the first and second steel channels, and a diagonal support is provided at the upper right end of the connection between the second and fourth steel channels. The two diagonal supports are used to fix the main body, increasing the stability of the main body and strengthening its load-bearing capacity, so that the main body has a stable structure.

[0004] However, in the above scheme, the rebar cage binding device is a non-adjustable design and is only suitable for rebar cages with one outer perimeter size. When it is necessary to bind rebar cages with different outer perimeter sizes, the rebar cage binding device cannot play a good supporting role due to the size mismatch, which has a certain impact on the binding of the rebar cage. Utility Model Content

[0005] To address the shortcomings of existing rebar cage binding devices where the size is not adjustable, this utility model provides a rebar cage binding device for anti-slide pile holes that is adaptable to rebar cages of different sizes and has good adaptability.

[0007] Furthermore, the axial limiting structure includes a base and a nut; the base and the nut are fixedly connected to the support rod, the bottom end of the control shaft is supported on the base, and the nut is located above the control shaft.

[0008] Furthermore, a rubber ring is provided on the contact surface between the base and the control shaft.

The support rod and the mounting base are detachable, facilitating disassembly of the device after the rebar cage is bound.

[0017] By setting up clamping plates, the clamping plates can initially limit the position of the reinforcing bars under the action of the threaded rods during the binding of the reinforcing cage, thus preventing the reinforcing bars from shifting during the binding process.

[0018] The tapered fixing rod allows for quick and easy insertion of the mounting base into the ground to secure the equipment. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] In this utility model, the terms "axial," "vertical," "radial," "upper," "vertical," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientation or positional relationship shown is for the purpose of describing the present invention only, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0027] Anti-slide pile hole reinforcement cage binding device, such as Figures 1-5 As shown, the system includes a mounting base 1, a support rod 3, a control shaft 4, and a steel reinforcement support body. The bottom end of the support rod 3 is detachably connected to the center of the mounting base 1. For example, the support rod 3 and the base 1 can be connected via a plug-in slot; or the mounting base 1 has a threaded hole 2 at its top center, and the bottom end of the support rod 3 is threaded into the threaded hole 2. The control shaft 4 is coaxially mounted on the support rod 3 and rotatably engages with it. That is, the control shaft 4 is mounted outside the support rod 3, and when the support rod 3 is fixed, the control shaft 4 can rotate around it. For example, the control shaft 4 and the support rod 3 can be connected using a rolling bearing or a sliding bearing; alternatively, the inner wall of the control shaft 4 can directly slide against the outer wall of the support rod 3. An axial limiting structure is provided to restrict the relative position of the control shaft 4 and the support rod 3 along the axial direction. The function of the axial limiting structure is to prevent the control shaft 4 from moving axially along the support rod 3 during installation, facilitating installation and preventing safety accidents. The control shaft 4 has an inwardly recessed connecting groove 6 on its outer periphery. The steel reinforcement support body includes multiple adjusting rings 8 whose bottom ends are movably supported on the mounting base 1. The multiple adjusting rings 8 encircle the control shaft 4 to form a cylindrical structure coaxial with the control shaft 4. Each adjusting ring 8 is provided with a control plate 7 between itself and the control shaft 4. The inner end of the control plate 7 is hinged to the connecting groove 6 of the control shaft 4, and the outer end is hinged to the inner wall of the adjusting ring 8. The top of the support rod 3 is fixedly connected to a limiting plate 10. The top of each adjusting ring 8 is connected to the limiting plate 10 through a radial limiting guide structure. The radial limiting guide structure first realizes the connection between the adjusting ring 8 and the limiting plate 10, and then guides the adjusting ring 8 to retract or expand radially. In this configuration, the control plate 7 and the control shaft 4 form a rotating structure. When the control shaft 4 rotates, it can drive the control plate 7 to rotate and extend or retract into the connecting groove 6, thereby driving the adjusting ring 8 to expand outward or retract inward, thus realizing the diameter of the cylindrical structure formed by multiple adjusting rings 8.

[0028] Multiple sets of connecting grooves 6 are equally spaced vertically along the control shaft 4. Each set of connecting grooves 6 contains a control plate 7 corresponding to the adjusting ring 8. This allows for multiple vertical connections between the adjusting ring 8 and the control shaft 4, further ensuring the stability and reliability of the adjusting ring 8.

[0029] The axial limiting structure can have various structures. The support rod 3 is machined with a shoulder, a limiting pin, etc. In this embodiment, the axial limiting structure includes a base 5 and a nut 9. The support rod 3 is fixedly connected with the base 5 and the nut 9 which is threadedly connected to it. The bottom end of the control shaft 4 is supported on the base 5, and the nut 9 is located above the control shaft 4.

[0030] In order to reduce wear on the base 5, in this embodiment, a rubber ring is provided on the contact surface between the base 5 and the control shaft 4.

[0031] The radial limiting guide structure can take many forms, such as guide rails and sliders. In this embodiment, the top end of the adjusting ring 8 is fixedly connected to a slider 11; the limiting plate 10 is provided with multiple slides 16 axially around the support rod 3, and the slides 16 extend radially along the support rod 3; the slider 11 at the top end of the adjusting ring 8 is inserted into the corresponding slide 16 and slides along the support rod 3 in a radial manner with the slide 16 to form the radial limiting guide structure.

[0032] There can be three or four adjusting rings 8, but if the number of adjusting rings 8 is too small, the size of each ring will be large, which is not conducive to adjustment; if the number of adjusting rings 8 is too large, the structure will become complicated. In this embodiment, there are three adjusting rings 8; there are three sliders 11; the limiting plate 10 is Y-shaped, and each branch is provided with a slide rail 16. The adjusting rings 8 drive the sliders 11 to slide in the corresponding slide rails 16 through the control plate 7. The adjusting rings 8 are subjected to radial thrust, which drives the sliders 11 to slide radially along the limiting plate 10, thereby achieving the purpose of controlling the size adjustment of the adjusting rings 8.

[0033] To limit the bottom end of the adjusting ring 8, preferably, the top of the mounting base 1 is provided with multiple sliding grooves 13 arranged in a circumferential array with its center as the center point, and each sliding groove 13 extends radially along the array. A clamping plate 15 is slidably connected within each sliding groove 13, and the top end of the clamping plate 15 extends vertically upward. A threaded rod 14 is provided on the outside of the clamping plate 15, and the threaded rod 14 is threadedly connected to the mounting base 1, with its end rotatably engaged with the clamping plate 15. The clamping plate 15 can provide initial limiting treatment for the reinforcing bars, preventing displacement of the reinforcing bars during binding. By tightening the threaded rod 14, the clamping plate 15 can be controlled to move closer to the reinforcing bars along the sliding grooves 13; after binding is completed, the clamping plate 15 can be controlled to move away from the reinforcing bars along the sliding grooves 13 to facilitate the removal of the bound reinforcing cage.

[0034] A fixing rod 12 is fixedly connected to the bottom of the mounting base 1. The fixing rod 12 is tapered and is located at the center of the mounting base 1. This allows the mounting base 1 to be quickly inserted into the ground and the device to be stabilized using the fixing rod 12.

[0035] The working principle and usage process of this utility model are as follows: First, the mounting base 1 can be quickly inserted into the ground by fixing rod 12 to stabilize the equipment. Then, the reinforcing bar can be leaned against the outer wall of the adjusting ring 8, and the threaded rod 14 can be turned. The threaded rod 14 controls the clamping plate 15 to slide along the slide groove 13 towards the reinforcing bar, which performs preliminary limiting treatment on the reinforcing bar to prevent displacement during binding. Then, the workers can start binding the reinforcing bar. After binding is completed, the adjusting ring 8 can be manually controlled to rotate, so that the support rod 3 is unscrewed from the inside of the mounting base 1. Then, the adjusting ring 8 is lifted upward, so that the adjusting ring 8 drives the support rod 3 to be taken out from the inside of the bound reinforcing bar cage. Then, the reinforcing bar cage is removed, and finally, the mounting base 1 and fixing rod 12 are pulled out from the ground.

[0036] When tying the reinforcing cage, since the reinforcing cages of different sizes are different, when it is necessary to adjust the radius of the area surrounded by the adjusting ring 8, the control shaft 4 can be rotated to rotate around the support rod 3. When the control shaft 4 rotates, it will push the control plate 7 to rotate outward along the connection with the connecting groove 6. During the rotation, a thrust is applied to the adjusting ring 8, so that the adjusting ring 8 drives the slider 11 to slide radially along the limiting plate 10, thereby achieving the purpose of adjusting the size of the adjusting ring 8. Finally, the threaded rod 14 is tightened to fix the control shaft 4.

[0037] When rotating the control shaft 4, the gap between the top of the adjusting ring 8 and the limiting plate 10 can be used as the process space, and the control shaft 4 can be rotated manually or in conjunction with other driving tools.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
