[0002] With the vigorous development of modern construction engineering, complex structures such as high-rise buildings and heavy industrial plants are constantly emerging, which puts forward stringent requirements on the bearing capacity and stability of foundation engineering. Steel-concrete composite columns have been widely used in various projects due to their significant advantages such as high bearing capacity, good seismic performance and convenient construction. The construction of steel-concrete composite columns usually involves directly placing the steel pipe column into the pit, then placing the reinforcing cage, and finally pouring concrete to form a steel-concrete composite column.

[0003] Traditional steel-concrete composite column pile construction methods have many drawbacks, including long construction cycles, difficulty in quality control, and high costs. In particular, there are technical challenges in controlling the verticality of the steel-concrete composite column, preventing concrete backflow, and preventing the rebar cage from floating, which seriously restrict construction efficiency and project quality. In view of this, we propose a rapid connection and positioning device for steel-concrete composite piles. Utility Model Content

The three sets of T-shaped interlocking plates are distributed in a fan shape, and several sets of ball bearings are rolled on the outer side of the T-shaped interlocking plates.

[0007] Preferably, the top and bottom of the sector block are provided with welding blocks corresponding to the T-shaped interlocking plate on the side facing the ball, and an adjusting screw is screwed onto the welding block, one end of which is rotatably connected to the ball.

[0008] Preferably, the tool-type frame vertical adjustment and reinforcement platform includes a vertical support column and a horizontal connecting rod. The vertical support column is connected and fixed by the horizontal connecting rod, and the vertical support column and the horizontal connecting rod are connected to form a frame structure. The bottom end of the vertical support column is a nail pile, and the fan-shaped block is arranged on the vertical support column.

[0009] Preferably, the anti-backflow ring is composed of two sets of semi-circular perforated steel plates, and both ends of the outer sides of the two sets of semi-circular perforated steel plates are provided with connecting lugs, and connecting bolts are screwed between the corresponding connecting lugs of the two sets of semi-circular perforated steel plates.

[0010] Preferably, the positioning connection structure includes a positioning rod, which is movably arranged at the top of the vertical support column. An upper positioning plate is arranged at the outer end of the positioning rod. A fine-tuning screw is screwed onto one end of the upper positioning plate, and a lower positioning plate is rotatably arranged through the bottom end of the upper positioning plate via the fine-tuning screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through its designed tool-type sleeve-style vertical adjustment and reinforcement platform, adjustable positioning structure, positioning connection structure, and anti-backflow ring, allows for efficient construction of steel-concrete composite piles. First, the tool-type sleeve-style vertical adjustment and reinforcement platform is fixed into the pit. Then, the adjustable positioning structure at the top of the tool-type sleeve-style vertical adjustment and reinforcement platform is adjusted so that the distance between the two symmetrical sets of adjustable positioning structures is the same as the inner diameter of the steel pipe column. Next, the steel pipe column is placed into the pit. At this point, the adjustable positioning structure around the tool-type sleeve-style vertical adjustment and reinforcement platform can limit the movement of the steel pipe column, ensuring that it is placed vertically into the pit, thus guaranteeing the verticality of the steel pipe column. Then, the anti-backflow ring is installed on the outside of the steel pipe column, and the reinforcing cage is placed inside. After the reinforcing cage is in place, the positioning connection structure is installed on the top of the tool-type sleeve-style vertical adjustment and reinforcement platform. The positioning holes in the positioning connection structure fit onto the corresponding vertical main reinforcement bars of the reinforcing cage. Finally, the fine-tuning screw is turned... The lower positioning plate descends, pressing against the circular main reinforcement bars of the steel cage, thus achieving the positioning effect of the steel cage. Therefore, with the cooperation of the tool-type frame vertical adjustment and reinforcement platform, adjustable positioning structure, and positioning connection structure, the tool-type frame vertical adjustment and reinforcement platform, steel pipe column, and steel cage are quickly connected and accurately positioned, ensuring the verticality of the steel pipe column, improving construction accuracy and quality. It also effectively prevents the steel cage and steel pipe column from floating during concrete pouring, enhancing stability during construction. Furthermore, the anti-backflow ring effectively filters and separates groundwater from the concrete, preventing concrete backflow and ensuring smooth concrete pouring and pile quality. In summary, it effectively guarantees the construction effect and quality of steel pipe concrete column piles, solving the current technical problem of poor construction effect of steel pipe concrete column piles. Therefore, this utility model has the advantage of better construction effect and quality of steel pipe concrete column piles.

[0015] 2. In the adjustable positioning structure of this utility model, three sets of T-shaped interlocking plates are arranged on the outer arc surface of the fan-shaped block. The three sets of T-shaped interlocking plates are arranged in a fan shape, and the front end of each set of three T-shaped interlocking plates is rolled with ball bearings. Therefore, when the three sets of fan-shaped T-shaped interlocking plates are pulled out to contact the steel pipe column, the larger the inner diameter of the steel pipe column, the larger the combination distance between the three sets of T-shaped interlocking plates and the inner wall of the steel pipe column. This makes the vertical positioning effect of the steel pipe column more stable and reliable, thus achieving a better positioning effect. Furthermore, the rolling contact friction between the T-shaped interlocking plates and the steel pipe column through the ball bearings can effectively ensure that the T-shaped interlocking plates reduce friction while vertically limiting the steel pipe column, so that the steel pipe column can fall vertically smoothly and avoid jamming or deflection, further ensuring the vertical positioning effect of the T-shaped interlocking plates on the steel pipe column.

[0023] like Figures 1 to 5 As shown, this utility model relates to a rapid connection and positioning device for steel-concrete composite piles, comprising a steel pipe column 1 and a reinforcing cage 2. The reinforcing cage 2 is arranged outside the steel pipe column 1, and an anti-backflow ring 6 is arranged outside the reinforcing cage 2. A tool-type sleeve-style vertical adjustment and reinforcement platform 3 is arranged in the center inside the steel pipe column 1. Several sets of adjustable positioning structures 4 are arranged at equal intervals around the top of the tool-type sleeve-style vertical adjustment and reinforcement platform 3, and the adjustable positioning structures 4 are in contact with the inner wall of the steel pipe column 1. Several sets of positioning connection structures 5 are arranged at equal intervals on the top of the steel pipe column 1, and the positioning connection structures 5 are connected to the reinforcing cage 2. The positioning connection structure 5 includes a positioning rod 5. 01. The positioning rod 501 is movably arranged at the top of the vertical support column 301. An upper positioning plate 502 is arranged at the outer end of the positioning rod 501. A fine adjustment screw 503 is screwed onto one end of the upper positioning plate 502. A lower positioning plate 504 is rotatably arranged through the bottom end of the upper positioning plate 502. Positioning holes 505 are opened on both the lower positioning plate 504 and the upper positioning plate 502, and the positions of the positioning holes 505 correspond. A concave seat 506 is sleeved on the positioning rod 501. The concave seat 506 is arranged at the top of the vertical support column 301. A fixing bolt 507 is screwed onto the top of the concave seat 506.

[0024] During the construction of steel-concrete composite piles, the tool-type scaffolding vertical adjustment and reinforcement platform 3 is first fixed into the pit. Then, the adjustable positioning structure 4 at the top of the tool-type scaffolding vertical adjustment and reinforcement platform 3 is adjusted so that the spacing between the two symmetrical sets of adjustable positioning structures 4 is the same as the inner diameter of the steel pipe column 1. The steel pipe column 1 is then placed into the pit. At this point, the adjustable positioning structure 4 around the tool-type scaffolding vertical adjustment and reinforcement platform 3 can limit the movement of the steel pipe column 1, ensuring that it is placed vertically into the pit, thus ensuring the verticality of the steel pipe column 1. Then, the anti-backflow ring 6 is installed on the outside of the steel pipe column 1, and the reinforcing cage 2 is placed inside. After the reinforcing cage 2 is in place, the positioning connection structure 5 is installed on the top of the tool-type scaffolding vertical adjustment and reinforcement platform 3. The positioning holes 505 in the positioning connection structure 5 are fitted onto the corresponding vertical main reinforcement bars of the reinforcing cage 2. Tightening the fine-tuning screw 503 causes the lower positioning plate 504 to descend, pressing it against the circular main reinforcement bar of the steel cage 2, thus achieving the positioning effect of the steel cage 2. Therefore, with the cooperation of the tool-type frame vertical adjustment and reinforcement platform 3, the adjustable positioning structure 4, and the positioning connection structure 5, the tool-type frame vertical adjustment and reinforcement platform 3, the steel pipe column 1, and the steel cage 2 are quickly connected and accurately positioned, ensuring the verticality of the steel pipe column 1, improving construction accuracy and quality, and effectively preventing the steel cage 2 and the steel pipe column 1 from floating during concrete pouring, enhancing the stability during construction. Furthermore, the anti-backflow ring 6 can effectively filter and separate groundwater and concrete, preventing concrete backflow, ensuring the smooth progress of concrete pouring and the quality of the pile body. In summary, it can effectively guarantee the construction effect and quality of the steel pipe concrete column pile.

[0025] Specifically, the tool-type frame vertical adjustment and reinforcement platform 3 includes a vertical support column 301 and a horizontal connecting rod 302. The vertical support column 301 is connected and fixed by the horizontal connecting rod 302, and the vertical support column 301 and the horizontal connecting rod 302 are connected to form a frame structure. The bottom end of the vertical support column 301 is a nail pile 303, and the fan-shaped block 401 is arranged on the vertical support column 301. The frame structure formed by the combination of the vertical support column 301 and the horizontal connecting rod 302 is fixed to the pit by the nail pile 303 to ensure the verticality of the frame, so as to facilitate the subsequent use of the adjustable positioning structure 4 to vertically limit the steel pipe column 1.

[0026] Furthermore, the anti-backflow ring 6 is composed of two sets of semi-circular perforated steel plates 601, and both ends of the outer side of the two sets of semi-circular perforated steel plates 601 are provided with connecting lugs 602, and connecting bolts 603 are screwed between the corresponding connecting lugs 602 of the two sets of semi-circular perforated steel plates 601; the two sets of semi-circular perforated steel plates 601 are fitted onto the outside of the steel pipe column 1, and then the connecting bolts 603 are screwed into the connecting lugs 602 of the two sets of semi-circular perforated steel plates 601, so that the two sets of semi-circular perforated steel plates 601 can be combined and fixed to the steel pipe column 1, which is convenient for disassembly and assembly.

[0027] Furthermore, a connecting rod 509 is inserted through the inner end of the positioning rod 501, a pin 5010 is inserted at the top of the connecting rod 509, and a counterweight 508 is arranged at the bottom of the connecting rod 509. The connecting rod 509 is hung on the positioning rod 501 through the pin 5010. The number of counterweights 508 can be adjusted as needed to increase the weight and reinforce the tool-type frame vertical adjustment and reinforcement platform 3, thereby ensuring the stability of the tool-type frame vertical adjustment and reinforcement platform 3. Then, in conjunction with the positioning connection structure 5, the rebar cage 2 can be better positioned, which can effectively prevent the rebar cage 2 and the steel pipe column 1 from floating.

[0028] In an embodiment of this utility model, the adjustable positioning structure 4 includes a fan-shaped block 401. Three sets of T-shaped interlocking plates 402 are arranged on the outer arc surface of the fan-shaped block 401. The three sets of T-shaped interlocking plates 402 are distributed in a fan shape. Several sets of balls 403 are rolled on the outer side of the T-shaped interlocking plates 402. Welding blocks 404 corresponding to the T-shaped interlocking plates 402 are arranged on the top and bottom sides of the fan-shaped block 401 facing the balls 403. An adjusting screw 405 is screwed onto the welding block 404. One end of the adjusting screw 405 is rotatably connected to the balls 403.

[0029] By adjusting the extension length of the T-shaped insertion plate 402 by turning the adjusting screw 405, when the three sets of fan-shaped T-shaped insertion plates 402 contact the steel pipe column 1, the larger the inner diameter of the steel pipe column 1, the larger the combination distance between the three sets of T-shaped insertion plates 402 and the inner wall of the steel pipe column 1. This makes the vertical positioning effect of the steel pipe column 1 more stable and reliable, thus achieving a better positioning effect. Furthermore, the T-shaped insertion plate 402 rolls and contacts the steel pipe column 1 through the ball bearing 403, which effectively ensures that the T-shaped insertion plate 402 reduces friction while vertically limiting the steel pipe column 1. This allows the steel pipe column 1 to fall smoothly vertically, avoiding jamming or deflection, and further ensuring the vertical positioning effect of the T-shaped insertion plate 402 on the steel pipe column 1.

[0030] Working Principle: This embodiment provides a quick connection and positioning device for steel-concrete composite piles. First, during the construction of the steel-concrete composite pile, the tool-type sleeve adjustment and reinforcement platform 3 is fixed in the pit. Then, the adjustable positioning structure 4 at the top of the tool-type sleeve adjustment and reinforcement platform 3 is adjusted so that the distance between the two symmetrical sets of adjustable positioning structures 4 is the same as the inner diameter of the steel pipe column 1. Then, the steel pipe column 1 is placed into the pit. At this time, the adjustable positioning structure 4 around the tool-type sleeve adjustment and reinforcement platform 3 can limit the steel pipe column 1, ensuring that the steel pipe column 1 can be placed vertically into the pit, that is, ensuring the verticality of the steel pipe column 1 placed into the pit. Then, the anti-backflow ring 6 is installed on the outside of the steel pipe column 1, and the reinforcing cage 2 is placed in. After the reinforcing cage 2 is placed, the positioning connection structure 5 is installed on the top of the tool-type sleeve adjustment and reinforcement platform 3. The positioning connection structure 5 has 505 positioning holes. On the vertical main reinforcement corresponding to the steel cage 2, the fine-tuning screw 503 is turned to drive the lower positioning plate 504 to descend, so that it presses against the circular main reinforcement of the steel cage 2, thereby achieving the positioning effect of the steel cage 2. Therefore, with the cooperation of the tool-type frame vertical adjustment and reinforcement platform 3, the adjustable positioning structure 4, and the positioning connection structure 5, the tool-type frame vertical adjustment and reinforcement platform 3, the steel pipe column 1, and the steel cage 2 are quickly connected and accurately positioned, ensuring the verticality of the steel pipe column 1, improving the construction accuracy and quality, and effectively preventing the steel cage 2 and the steel pipe column 1 from floating during concrete pouring, enhancing the stability during construction. In addition, the anti-backflow ring 6 can effectively filter and separate groundwater and concrete, prevent concrete backflow, and ensure the smooth progress of concrete pouring and the quality of the pile. In summary, it can effectively guarantee the construction effect and quality of the steel pipe concrete column pile.

[0031] Secondly, by adjusting the extension length of the T-shaped insertion plate 402 by turning the adjusting screw 405, when the three sets of fan-shaped T-shaped insertion plates 402 contact the steel pipe column 1, the larger the inner diameter of the steel pipe column 1, the larger the combination distance between the three sets of T-shaped insertion plates 402 and the inner wall of the steel pipe column 1. This makes the vertical positioning effect of the steel pipe column 1 more stable and reliable, thus achieving a better positioning effect. Furthermore, the T-shaped insertion plate 402 rolls and contacts the steel pipe column 1 through the ball bearing 403, which effectively ensures that the T-shaped insertion plate 402 reduces friction while vertically limiting the steel pipe column 1. This allows the steel pipe column 1 to fall smoothly and vertically, avoiding jamming or deflection, further ensuring the vertical positioning effect of the T-shaped insertion plate 402 on the steel pipe column 1.
