Description

Technical Field

[0001] This utility model belongs to the field of bored pile construction technology, and in particular relates to a steel cage fixing device for the borehole opening of bored piles. Background Technology

[0002] Drilled cast-in-place piles are piles made by forming pile holes in the foundation soil through mechanical drilling, steel pipe extrusion, or manual excavation on the engineering site, placing a steel cage inside, and pouring concrete. Depending on the hole-forming method, cast-in-place piles can be divided into driven cast-in-place piles, drilled cast-in-place piles, and excavated cast-in-place piles.

[0003] During the construction of bored piles, the reinforcing cage needs to be placed into the foundation soil hole. Since the length of the reinforcing cage is less than the length in the foundation soil, it needs to be lengthened by welding. During welding, the reinforcing cage needs to be fixed. Therefore, we need to design a reinforcing cage fixing device for the borehole of bored piles. It adopts a centering and clamping mechanism to fix the reinforcing cage. Since the diameter of each bored pile is different, this structure is suitable for fixing reinforcing cages of bored piles with different diameters, which improves the stability of the reinforcing cage in the foundation soil hole and the applicability of the product.

[0024] In the following description, embodiments of the present invention for fixing a reinforcing cage at the borehole opening of a bored pile will be described with reference to the accompanying drawings.

[0025] Figure 1-6This invention illustrates a steel cage fixing device for the borehole opening of a bored pile according to an embodiment of the present invention. It includes a lower base plate 1 placed on the ground. An annular groove 15 is formed at the top of the lower base plate 1. A rotating disk 3 is disposed at the top of the lower base plate 1. A rotating ring 2 is fixedly connected to the bottom of the rotating disk 3. The rotating ring 2 is rotatably connected to the inner cavity of the annular groove 15. Through the arrangement of the rotating ring 2 and the rotating disk 3, the rotating disk 3 guides the rotating ring 2 during rotation, preventing the rotating disk 3 from rotating within the inner cavity of the annular groove 15. To prevent offset phenomena and improve the stability of the rotating disk 3 during rotation, multiple arc-shaped blocks 4 are fixedly connected to the top of the rotating disk 3, and multiple triangular fixing blocks 5 are also fixedly connected to the top of the rotating disk 3. Side baffles 6 are fixedly connected to both sides of the multiple triangular fixing blocks 5. An L-shaped plate 7 is slidably connected to the top of the rotating disk 3, and the L-shaped plate 7 is slidably connected between the two side baffles 6. The arc-shaped blocks 4 are slidably connected to the grooves opened at the bottom of the L-shaped plate 7. A rotating block 8 is fixedly connected to one side of the rotating disk 3, and a sliding rod is fixedly connected to the bottom of the rotating block 8. 14. An elongated hole is provided at the bottom of the inner cavity of the fixed frame 9. The slide rod 14 is slidably connected to the inner wall of the elongated hole in the fixed frame 9. The arrangement of the rotating block 8 and the slide rod 14 guides the slide rod 14 as it slides within the groove of the fixed frame 9, improving the stability of the slide rod 14 during the sliding process. The fixed frame 9 is fixedly connected to the left side of the lower base plate 1. A cylinder 12 is installed in the inner cavity of the fixed frame 9. A support block 10 is fixedly connected to the bottom of the inner cavity of the fixed frame 9. The cylinder 12 is fixedly installed on the top of the support block 10. The cylinder 12 is supported by the support block 10 during use, which improves the stability of the cylinder 12. The rotating block 8 is rotatably connected to the rotating rod 11, and the top of the rotating rod 11 is fixedly connected to the connecting frame 13. The output end of the cylinder 12 is fixedly connected to the connecting frame 13. The bottom of the L-shaped plate 7 is provided with a groove for the arc-shaped block 4 to slide. The groove is adapted to the arc-shaped block 4. The surfaces of the bottom plate 1 and the rotating disc 3 are provided with holes for the steel cage to pass through. The four L-shaped plates 7 face each other and are in contact with the outer ring of the steel cage.

[0026] Working principle: When using this invention, the user places the bottom plate 1 around the foundation soil hole. Then, the output shaft of the cylinder 12 drives the connecting frame 13 to move. At this time, the connecting frame 13 will drive the sliding rod 14 to move via the rotating rod 11. Due to the setting of the rotating rod 11, when the connecting frame 13 drives the sliding rod 14 to move, the rotating rod 11 will rotate on the surface of the rotating block 8, thereby fixing the cylinder 12. At the same time, the sliding rod 14 at the bottom of the rotating block 8 will slide forward in the groove opened on the surface of the fixed frame 9. Subsequently, the connecting frame 13 will drive the rotating block 8 to rotate, which in turn will drive the rotating disk 3 to rotate. Since the rotating ring 2 at the bottom of the rotating disk 3 will rotate within the cavity of the annular groove 15, the arc-shaped block 4 at the top of the rotating disk 3 will slide within the groove at the bottom of the L-shaped plate 7. Due to the rotation of the arc-shaped block 4, the arc-shaped block 4 will drive the L-shaped plate 7 to move inward, which will cause the L-shaped plate 7 to slide between the two side baffles 6. Then, the four L-shaped plates 7 moving towards each other will fix the steel cage, resulting in a fixed phenomenon.

[0027] In summary, this rebar cage fixing device for the borehole of bored piles, through the coordinated use of rotating block 8, cylinder 12, and connecting frame 13, allows rotating disc 3 to rotate within the annular groove 15. The coordinated use of arc-shaped block 4, triangular fixing block 5, and side baffle 6 allows L-shaped plates 7 to slide towards each other, clamping and fixing the rebar cage, thus ensuring its stability. This achieves the goal of fixing the rebar cage using a centering clamping mechanism. Since the diameter of each bored pile is different, this structure is suitable for fixing rebar cages of bored piles with different diameters, improving the stability of the rebar cage within the foundation soil hole and enhancing the product's applicability.
