Description

Technical Field

[0001] This utility model relates to the technical field of bored pile construction, specifically to the installation and positioning structure of the reinforcing cage for bored piles. Background Technology

[0002] A reinforcing cage is a cage structure made of reinforcing steel bars. In bored pile construction, it is placed inside the borehole, and then concrete is poured in to form a robust pile. The reinforcing cage acts like a sturdy "armor" for the bored pile, enhancing its load-bearing capacity and stability. Precise placement of the reinforcing cage is crucial during borehole construction; therefore, an installation and positioning structure for the bored pile reinforcing cage is needed to assist in its positioning and installation.

[0003] The existing technology has the following shortcomings: The existing technology, disclosed in publication number CN216379525U, discloses a positioning device for a drilled pile reinforcement cage. "It includes an annular positioning plate, multiple positioning components evenly arranged on the inner side of the annular positioning plate along the circumferential direction, and a hook assembly for suspending it at the top of a steel casing. The annular positioning plate includes at least two arc-shaped plates connected end-to-end, the outer side of the arc-shaped plates matching the inner circular surface of the steel casing. The positioning components include a mounting base and a positioning roller mounted on the mounting base, the axis of the positioning roller being perpendicular to the axis of the arc-shaped plate. The hook assembly includes a support and a hook vertically mounted on the support."

[0004] When the above-mentioned borehole pile reinforcement cage positioning device is used, the hook assembly is used to install and fix the arc plate, and the positioning roller is used to position the reinforcement cage. However, the overall size of the reinforcement cage is not fixed, while the size between the positioning rollers is fixed. The applicability of the positioning device is poor. At the same time, when the reinforcement cage is offset, the position of the reinforcement cage needs to be manually adjusted, which poses a safety hazard. In addition, manual adjustment is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0022] This utility model provides a technical solution: such as Figure 2As shown in this embodiment, the installation and positioning structure of the drilled pile reinforcement cage includes a steel casing 1, which is coaxially arranged with the pile hole. Multiple sets of fixing frames 2 are provided on the top of the steel casing 1. The fixing frames 2 have a U-shaped structure. A positioning component is provided on the top of the steel casing 1, which can position and install the reinforcement cage. A first-order threaded rod 3 is installed inside the fixing frame 2. The first-order threaded rod 3 is screwed onto the fixing frame 2. A clamping device 4 is rotatably installed at the end of the first-order threaded rod 3. The clamping device 4 has an arc-shaped cross-section. The steel casing 1 can serve as a positioning reference to ensure accurate positioning and installation of the reinforcement cage. With the fixing frames 2, the first-order threaded rod 3, and the clamping device 4, the fixing frames 2 and the steel casing 1 can be installed and fixed. With the fixing frames 2 being detachable, the user can select the number of fixing frames 2 according to the size of the steel casing 1.

[0023] like Figure 3 and Figure 4As shown, the positioning assembly includes a stabilizing frame 5, multiple sets of limiting rods 6, sliding blocks 7, two sets of limiting blocks 8, a first damping spring 9, a second damping spring 10, a second threaded rod 11, a fixed cylinder 12, a return spring 13, a support column 14, a limit switch 15, a mounting frame 16, a limiting roller 17, and a fixing frame 18. The stabilizing frame 5 is welded to the top of the fixing frame 2. The multiple sets of limiting rods 6 are symmetrically arranged on the inner wall of the stabilizing frame 5. The sliding blocks 7 are slidably sleeved on the outside of the limiting rods 6. The two sets of limiting blocks 8 are symmetrically installed on the side walls of the sliding blocks 7. The first damping spring 9 is sleeved on the upper part of the limiting rod 6, and the second damping spring 10 is sleeved on the limiting rod. At the lower part of 6, the second threaded rod 11 is installed inside the sliding block 7, the fixed cylinder 12 is installed at the bottom of the stabilizing frame 5, the return spring 13 is installed inside the fixed cylinder 12, the support column 14 is installed at the top of the return spring 13, the limit switch 15 is installed at the top of the support column 14, the mounting frame 16 is rotatably installed at the end of the second threaded rod 11, the limiting roller 17 is rotatably installed inside the mounting frame 16, the fixed frame 18 is installed on the side wall of the mounting frame 16, the stabilizing frame 5 has a U-shaped cross-section, and two sets of sliding openings are symmetrically provided on the inner wall of the stabilizing frame 5. The limiting block 8 and the limiting rod 6 are slidably arranged, and the first damping spring 9 is located between the limiting block 8 and the sliding rod 6. Above the sliding block 7, the second damping spring 10 is located below the limiting block 8 and the sliding block 7. The second threaded rod 11 is threadedly engaged with the sliding block 7. A cylinder 19 is bolted to the side wall of the fixing frame 18. A push plate 20 is installed at the output end of the cylinder 19. The support column 14 is slidably disposed with the fixing cylinder 12. The limit switch 15 is connected to the cylinder 19. The fixing frame 18 has an L-shaped cross-section. The user can adjust the distance between the limiting rollers 17 by rotating the second threaded rod 11 to facilitate the positioning of steel cages of different sizes. With the cooperation of multiple sets of limiting rollers 17, the suspended steel cage can be positioned and installed. When the steel cage is out of the... When the rebar cage deviates, the stirrups of the rebar cage will cause the limiting roller 17 and the mounting frame 16 to move downward.

[0024] This utility model provides an installation and positioning structure for the reinforcing cage of bored piles, and its specific working principle is as follows:

[0025] When using this installation and positioning structure for the reinforcing cage of a bored pile, after drilling the pile hole, the construction personnel hoist the steel casing 1 into the pile hole. The steel casing 1 is coaxially set with the pile hole and can serve as a positioning reference to ensure accurate positioning and installation of the reinforcing cage. The construction personnel place the fixing frame 2 on top of the steel casing 1 and rotate the first threaded rod 3. The rotation of the first threaded rod 3 causes it to move, which in turn moves the clamping device 4, thus fixing the fixing frame 2 to the steel casing 1. With the detachable design of the fixing frame 2, the user can select the number of fixing frames 2 according to the size of the steel casing 1. The user can adjust the distance between the limiting rollers 17 by rotating the second threaded rod 11, which facilitates the positioning of reinforcing cages of different sizes. With the cooperation of multiple sets of limiting rollers 17, the hoisted reinforcing cage can be positioned. When the steel cage is positioned and installed, if the steel cage shifts, the stirrups of the steel cage will cause the limiting roller 17 and the mounting frame 16 to move downward. The downward movement of the mounting frame 16 will cause the sliding block 7 and the limiting block 8 to press down. With the setting of the limiting rod 6, the vertical downward movement of the sliding block 7 and the limiting block 8 can be ensured. The downward movement of the sliding block 7 and the limiting block 8 will cause the first damping spring 9 to stretch and the second damping spring 10 to compress until the sliding block 7 touches the limit switch 15. Then the cylinder 19 will start and drive the push plate 20 to move, which can push the steel cage to complete the adjustment of the position of the steel cage and ensure the accurate installation of the steel cage. With the setting of the support column 14, the fixing cylinder 12 and the return spring 13, the limit switch 15 can be protected. After the position of the steel cage is adjusted, the steel cage will no longer press on the mounting frame 16, and the sliding block 7 and the cylinder 19 will return to their original positions.
