Technical Field

[0001] The utility model relates to the technical field of cast-in-place pile construction, in particular to an anti-deviating stable cast-in-place pile. Background Art

[0002] Cast-in-place piles are piles made by pouring concrete or reinforced concrete into a hole in place. According to the different hole-forming methods, cast-in-place piles can be divided into bored cast-in-place piles, pipe-sinking cast-in-place piles, artificially dug cast-in-place piles, explosive expansion cast-in-place piles, etc. Cast-in-place piles are widely used in construction because of their advantages such as no vibration, no soil squeezing, low noise, and suitability for use in densely built urban areas.

[0003] At present, during the construction of cast-in-place piles, a crane is required to lift the steel cage into the pile hole pre-opened on the ground. However, due to the depth limit of the pile hole, it is difficult to accurately check the verticality of the steel cage after it is inserted into the pile hole. Once the steel cage is misaligned, the completed cast-in-place pile will be offset, which will not only seriously affect the subsequent construction progress, but also may pose a potential risk to the overall project quality. Therefore, ensuring the installation accuracy of the steel cage in the pile hole is crucial to the molding quality of the cast-in-place pile. In view of this, we propose an anti-deviated stable cast-in-place pile. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] This embodiment provides a technical solution:

[0028] See also Figure 1-Figure 6 , an anti-deviating stable cast-in-place pile, comprising a pile hole, in which a cast-in-place pile is installed. The cast-in-place pile comprises a pile body 1, and a steel cage 2 is installed inside the pile body 1; the steel cage 2 comprises a plurality of vertically arranged main rods 22, and a plurality of connecting rings 21 are installed on the outside of the plurality of main rods 22 from top to bottom; a plurality of anti-deviating components 23 are arranged between two adjacent connecting rings 21; the anti-deviating components 23 comprise two symmetrical connecting plates 231, and threaded holes 2311 are provided on the connecting plates 231; two end surfaces of the two connecting plates 231 close to the connecting rings 21 are fixed with connecting blocks 233, and two opposite end surfaces of the two connecting blocks 233 are provided with hanging grooves 2331, and the hanging grooves 2331 are hung and matched with the corresponding connecting rings 21; two end surfaces of the two connecting plates 231 away from the connecting rings 21 are fixed with arch plates 232, and the outer wall of the arch plates 232 is pressed against the outer wall of the pile hole; a double-headed screw rod 235 is arranged between the two connecting plates 231, and the threads at both ends of the double-headed screw rod 235 are threadedly connected with the corresponding threaded holes 2311.

[0029] In this embodiment, the cross-section of the hanging groove 2331 is arc-shaped, and a plurality of anti-skid grooves are provided on the inner wall of the hanging groove 2331. The arc-shaped design facilitates the connection between the hanging groove 2331 and the connecting ring 21, and the design of the anti-skid grooves increases the connection stability between the anti-deviation component 23 and the connecting ring 21.

[0030] In this embodiment, the connecting plate 231, the arch plate 232 and the connecting block 233 are an integrally formed structure, and the connecting plate 231, the arch plate 232 and the connecting block 233 are all made of galvanized steel. The integrally formed connecting plate 231, the arch plate 232 and the connecting block 233 have better connection strength, ensuring the service life of the connecting plate 231, the arch plate 232 and the connecting block 233, and the galvanized steel material has the advantage of high structural strength, and the use of this material ensures the structural strength of the connecting plate 231, the arch plate 232 and the connecting block 233.

[0031] In this embodiment, the overall shape of the connecting ring 21 is annular, and the connecting ring 21 is tightly welded to the main rod 22. The tight welding method ensures the connection reliability between the connecting ring 21 and the main rod 22, and ensures the structural strength of the steel cage 2.

[0032] In this embodiment, the overall shape of the arch plate 232 is arc-shaped, and the outer wall of the arch plate 232 is smooth. When the steel cage 2 is placed in the pile hole, the outer wall of the arch plate 232 rubs against the inner wall of the pile hole, and the smooth arc design can reduce friction and improve the convenience of installation.

[0033] In this embodiment, an adjusting screw 234 is coaxially fixed at the center of the double-ended screw 235, and a plurality of anti-slip grooves are provided on the outer wall of the adjusting screw 234. The arrangement of the adjusting screw 234 facilitates the rotation of the double-ended screw 235, thereby improving the convenience of operation.

[0034] In this embodiment, a limiting block 236 is coaxially fixed at the end of the double-ended screw 235, and the diameter of the limiting block 236 is larger than the diameter of the double-ended screw 235. The setting of the limiting block 236 can prevent the double-ended screw 235 from escaping from the threaded hole 2311.

[0035] In this embodiment, two insertion holes 2322 are opened at the bottom of the upper arch plate 232, and two insertion rods 2321 are fixed on the top of the lower arch plate 232, and the insertion rods 2321 are plugged into the insertion holes 2322. This design can improve the connection stability of the two arch plates 232.

[0036] It can be understood that the thread winding directions at both ends of the double-headed screw 235 in this embodiment are opposite. When the double-headed screw 235 rotates, the connecting plates 231 on both sides can move synchronously relative to each other, thereby conveniently driving the connecting blocks 233 on both sides to move synchronously relative to each other. This design facilitates the assembly of the anti-deviance component 23 and the steel cage 2.

[0037] It should be added that the main rod 22 and the connecting ring 21 in the present embodiment are both made of alloy steel. Alloy steel has excellent strength and toughness, so that the steel cage 2 can maintain its stability and integrity when subjected to various complex forces and challenges of the external environment, thereby ensuring the safety and reliability of the project. At the same time, the steel cage 2 made of alloy steel also has excellent corrosion resistance and wear resistance, and can maintain its stable performance for a long time in various harsh environments, and can provide solid support and guarantee for the project.

[0038] When in use, the user first aligns the connecting blocks 233 at both ends of the connecting plate 231 with the connecting rings 21 on the upper and lower sides, and aligns the hanging groove 2331 with the connecting ring 21, and then the user rotates the adjusting screw 234, and the adjusting screw 234 drives the double-headed screw rod 235 to rotate. With the rotation of the double-headed screw rod 235, the two connecting plates 231 move inwardly relative to each other synchronously, and at the same time, the connecting plate 231 drives the connecting blocks 233 on both sides to move. When the hanging groove 2331 is hung with the connecting ring 21, the anti-deviation component 23 is installed; repeat the above steps to install multiple anti-deviation components 23 in sequence;

[0039] When placing the steel cage 2, the operator operates the crane to lift the steel cage 2 and place it in the pile hole. At this time, the arch plate 232 outside the steel cage 2 rubs against the inner wall of the pile hole and moves downward. When the steel cage 2 is completely placed in the pile hole, the steel cage 2 is stably placed.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
