Description

Technical Field

[0001] This utility model relates to the field of concrete square pile technology, specifically to a precast concrete irregular square pile. Background Technology

[0002] Precast concrete square piles are a commonly used building material, usually made of concrete or reinforced concrete. They can be divided into on-site precast piles and factory precast piles. Whether on-site or factory precast, the length of the pile body that can be precast is limited. When the length of the pile body required for construction exceeds the maximum length of the precast pile body, it is necessary to perform a pile splicing operation during the pile driving process. Generally, the splicing is carried out when the top of the previous pile body protrudes a certain height above the ground.

[0003] Currently, when splicing concrete square piles, the pile bodies of the upper and lower sections must be continuously adjusted to ensure that they are aligned and the misalignment does not exceed the specified value. The gap between the upper and lower joints is filled with steel plates of appropriate thickness and processed into wedge shapes. Then, carbon dioxide gas shielded welding is used to ensure the quality of the weld. Because existing concrete square piles lack auxiliary positioning structures and steel plate shims, the alignment operation is time-consuming and labor-intensive. In addition, the steel plate needs to be installed separately in the middle of the gap during welding, making the welding process cumbersome and time-consuming. The efficiency of the splicing operation needs to be further improved.

[0004] Therefore, a precast concrete irregular square pile is proposed. Utility Model Content

[0025] As Figs. 1 to 4As shown, a prefabricated concrete special-shaped square pile comprises a pile tip 1, a first pile body 2 fixedly installed on the top surface of the pile tip 1, a second pile body 5 fixedly installed on the top surface of the first pile body 2, a first rib ring 3 and a steel bucket-shaped block 4 fixedly installed on the side surface of the first pile body 2, the steel bucket-shaped block 4 being fixedly installed on the bottom surface of the first rib ring 3, a second rib ring 6 and a connecting bucket-shaped block 7 fixedly installed on the side surface of the second pile body 5, the connecting bucket-shaped block 7 being fixedly installed on the bottom surface of the second rib ring 6, a welding support block 8 fixedly installed on the top surface of the second pile body 5 and provided with a receiving groove 10 on the top surface, and a closure cover 11 being clamped and placed on the top surface of the welding support block 8, the closure cover 11 and the first pile body 2 being slidably arranged on the inner wall side surface of the receiving groove 10, and the welding support block 8 being provided with a connecting assembly 12 threadedly installed on the bottom surface of the closure cover 11.

[0026] More specifically, when splicing is needed, the relative fixation of the closure cover 11 and the welding support block 8 is released by rotating the connecting assembly 12, so that the closure cover 11 can be removed, the first pile body 2 of the next section of square pile can be slid into the inside of the receiving groove 10, and quick alignment can be achieved without workers repeatedly observing and adjusting the alignment degree. In addition, the steel bucket-shaped block 4 will be tightly attached to the top surface of the welding support block 8 under the action of gravity, and the splicing work can be completed by welding the steel bucket-shaped block 4 and the welding support block 8 at this time, without manually adding a steel plate at the gap between the two square piles. In this way, the welding process is simplified while the alignment accuracy is ensured, thereby effectively improving the splicing efficiency. In addition, when the closure cover 11 is not removed, the square pile can be inserted into the ground by hammering method, and the square pile can be inserted and installed by hammering method or static pressure method. The first rib ring 3 and the second rib ring 6 reduce the shear force received by the square pile during downward movement. The steel bucket-shaped block 4 and the connecting bucket-shaped block 7 reduce the resistance received by the square pile during downward movement. In addition, when the square pile is clamped and pressed by the static pressure method, the convex first rib ring 3 and the second rib ring 6 can prevent the equipment from slipping off from the side surface of the square pile, thereby ensuring the safety of the static pressure construction.

[0027] The number of the second rib ring 6 and the connecting bucket-shaped block 7 is several, and they are uniformly distributed on the side surface of the second pile body 5.

[0028] Specifically, after the static pressure equipment presses the square pile at equal intervals each time, it will be clamped on the surface of the second pile body 5 again. The several second rib rings 6 uniformly distributed can ensure that the clamping position is located between two second rib rings 6, thereby playing a good anti-slip effect.

[0029] The welding support block 8 comprises a limiting support block 801 fixedly installed on the top surface of the second pile body 5, a buffer hopper-shaped block 802 fixedly installed on the side surface of the second pile body 5 and fixedly installed on the bottom surface of the limiting support block 801, and sliding insertion holes 803 penetratingly formed at the top surface of the limiting support block 801 and the buffer hopper-shaped block 802 at four corners thereof.

[0030] Specifically, by installing the connecting assembly 12 in the sliding insertion holes 803 and fixing the closure cover 11 from the four corners, the coaxial fixation of the closure cover 11 and the second pile body 5 during hammering is ensured, the impact of the limiting support block 801 under the hammering force is dispersed by the hopper-shaped structure of the buffer hopper-shaped block 802, the function of strengthening support is achieved, the top surface of the limiting support block 801 is closely attached to the surface of the steel hopper-shaped block 4 and the closure cover 11, the contact area with the closure cover 11 is increased, and the impact from the closure cover 11 is buffered, the side edges of the steel hopper-shaped block 4 and the limiting support block 801 are welded during pile splicing, and the reliability of the connection is ensured.

[0031] The bottom surface of the steel hopper-shaped block 4 is fixedly provided with welding columns 9 at four corners thereof, and the welding columns 9 are slidably inserted into the inner wall surface of the sliding insertion holes 803.

[0032] Specifically, by slidingly inserting the welding columns 9 at the bottom surface of the steel hopper-shaped block 4 into the sliding insertion holes 803, the accuracy of the overlap of the bottom surface of the steel hopper-shaped block 4 and the top surface of the limiting support block 801 is further improved, the stability and accuracy of the steel hopper-shaped block 4 relative to the welding support block 8 are further improved by welding the welding columns 9 in the sliding insertion holes 803, and the accuracy and reliability of the pile splicing are further improved.

[0033] The closure cover 11 comprises a cover body 111, a hopper-shaped bottom 112 fixedly installed on the bottom surface of the cover body 111, the hopper-shaped bottom 112 being attached to the top surface of the limiting support block 801, an insertion block 113 fixedly installed on the bottom surface of the hopper-shaped bottom 112 and slidably arranged on the inner wall surface of the receiving groove 10, and threaded holes 114 formed at four corners of the bottom surface of the cover body 111 and the hopper-shaped bottom 112 and in which the connecting assembly 12 is threadedly installed.

[0034] Specifically, the insertion block 113 is slidably installed in the receiving groove 10, which not only helps to accurately position the cover body 111, but also fills the bottom of the cover body 111, avoids the hollow state of the cover body 111, and ensures that the cover body 111 will not be deformed under the impact of hammering, facilitating subsequent disassembly for pile splicing.

[0035] The connecting assembly 12 comprises a rotating block 121, a sliding column 122 and a rubber pad 124 are fixedly installed on the top surface of the rotating block 121, the rubber pad 124 is sleeved outside the sliding column 122, a threaded column 123 is fixedly installed on the top surface of the sliding column 122, the sliding column 122 is slidingly arranged on the inner wall side of the sliding insertion hole 803, and the threaded column 123 is threadedly installed on the inner wall surface of the threaded hole 114.

[0036] Specifically, by rotating the threaded column 123 to be inserted into the threaded hole 114, the closure cover 11 and the welding support block 8 are fixedly connected by the connecting assembly 12, at this time, the sliding column 122 is located in the sliding insertion hole 803, the rotating block 121 is located below the buffer hopper-shaped block 802, and the rubber pad 124 is located between the bottom surface of the buffer hopper-shaped block 802 and the top surface of the rotating block 121, at this time, the rubber pad 124 is deformed by extrusion, and the high elasticity and high damping coefficient characteristics of the rubber pad 124 are utilized to prevent the rotating block 121 from rotating, thereby ensuring the reliable degree of fixation of the closure cover 11, rotating the rotating block 121 drives the threaded column 123 to rotate, the connecting assembly 12 can be removed, and the closure cover 11 can be smoothly removed, thereby facilitating subsequent splicing operations.

[0037] In summary: by rotating the connecting assembly 12, the relative fixation of the closure cover 11 and the welding support block 8 is released, so that the closure cover 11 can be removed, the first pile body 2 of the next section of square pile can be slidingly inserted into the receiving groove 10, the fast alignment can be realized, the workers do not need to repeatedly observe and adjust the alignment degree, the steel hopper-shaped block 4 is tightly attached to the top surface of the welding support block 8 under the action of gravity, at this time, the steel hopper-shaped block 4 and the welding support block 8 are welded, the splicing work is completed, the workers do not need to manually add a steel plate at the gap between the two square piles, the welding process is simplified while the alignment accuracy is ensured, thereby effectively improving the splicing efficiency, and when the closure cover 11 is not removed, the square pile can be inserted into the ground by the hammering method, and the square pile can be inserted and installed by the hammering method or the static pressure method.
