Description

Technical Field

[0001] This utility model belongs to the field of concrete pipe pile technology, specifically relating to a concrete pipe pile joint assembly. Background Technology

[0002] Concrete pipe piles are structural components used in building foundations. They mainly consist of a cylindrical pile body, end plates, and steel sleeves. Currently, the joints of concrete pipe piles are mostly connected by flange bolts, and then the end plates are welded together. This connection method is extremely inconvenient in actual operation, greatly increases the assembly time, and has low practicality.

[0003] For example, a Chinese patent discloses a quick connector for concrete pipe piles (publication number CN218786833U), which includes a first pipe pile and a second pipe pile detachably connected to the bottom end of the first pipe pile. The bottom end of the first pipe pile has an end plate, and the top end of the second pipe pile has an end plate. The top end of the second end plate has a ring array of multiple sets of threaded connecting rods that can pass through the first end plate.

[0004] However, the aforementioned publicly available documents demonstrate convenient docking, saving time and effort in actual operation, significantly reducing assembly time, and minimizing the risk of misalignment during connection, making them highly practical. However, in practice, this patent requires inserting multiple arc-shaped positioning blocks into multiple arc-shaped positioning slots, and using multiple nuts and threaded connecting rods to fix the arc-shaped positioning blocks within the slots. The space occupied by the nuts is very small, making rotation of the nuts extremely inconvenient. Furthermore, the need for multiple nuts to secure a single arc-shaped positioning block results in a considerable time commitment for operators when tightening multiple nuts. Therefore, those skilled in the art have provided a solution to address the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this invention is to provide a concrete pipe pile joint assembly that can solve the problems mentioned in the background art, which require multiple arc-shaped positioning blocks to be inserted into multiple arc-shaped positioning grooves and multiple nuts and threaded connecting rods to fix the arc-shaped positioning blocks in the arc-shaped positioning grooves. However, the space occupied by the nuts is very small, making it very inconvenient to turn the nuts. Furthermore, one arc-shaped positioning block requires multiple nuts to fix, which results in workers spending a long time when tightening multiple nuts.

[0006] The specific technical solution adopted in this utility model is as follows: A concrete pipe pile joint assembly includes a first pipe pile and a second pipe pile detachably connected to the outer top of the first pipe pile. The top of the outer peripheral sidewall of the first pipe pile is fixedly provided with an annular plate 1, and the bottom of the outer peripheral sidewall of the second pipe pile is fixedly provided with an annular plate 2. The annular plate 1 and the annular plate 2 are fixedly connected to each other by a connecting assembly 1, and the first pipe pile and the second pipe pile are fixedly connected to each other by a connecting assembly 2. The connecting component includes a through arc-shaped groove symmetrically formed on the outer top surface of the annular plate 1, and an arc-shaped plate 1 fixed on the outer bottom surface of the annular plate 2 corresponding to one of the arc-shaped grooves. One end of each of the two arc-shaped plates 1 is slidably inserted into the inner side of the two arc-shaped grooves 1. A through screw hole 1 is formed on the outer side wall of each of the two arc-shaped plates 1. Arc-shaped positioning blocks are symmetrically fitted on the outer sides of the arc-shaped plates 1 and the annular plate 2. A mating groove 1 is formed at the bottom of the groove of each of the two arc-shaped positioning blocks, and a mating groove 2 is formed at the top of the groove of each of the two arc-shaped positioning blocks. A groove for avoiding the two arc-shaped plates 1 is formed at the center of the concave surface of each of the two arc-shaped positioning blocks. A through screw hole 2 that matches the screw hole 1 is formed at the center of the outer peripheral side wall of each of the two arc-shaped positioning blocks. A positioning screw 1 is threadedly connected to the inner side of both the screw hole 1 and the screw hole 2.

[0007] The present invention is further configured such that: the connecting component 2 includes a disc 1 disposed on the outer top surface of the pipe pile 1, a disc 2 disposed on the outer bottom surface of the pipe pile 2, a through-hole 5 is provided on the outer top surface of the disc 1 and the outer bottom surface of the disc 2, and a reserved hole adapted to the screw hole 5 is provided on the outer top surface of the pipe pile 1 and the outer bottom surface of the pipe pile 2, and the screw hole 5 and the reserved hole are fixed to each other by a positioning screw 2.

[0008] The present invention is further configured such that: a through arc-shaped groove 2 is symmetrically opened on the outer top surface of the disk 1, and an arc-shaped plate 2 adapted to the arc-shaped groove 2 is fixed on the outer bottom surface of the disk 2, and the two arc-shaped plates 2 are respectively slidably inserted into the inner side of the two arc-shaped grooves 2.

[0009] The present invention is further configured such that: the outer peripheral sidewall of the disc one is provided with a screw hole six that communicates with the arc groove two, and the outer peripheral sidewalls of the two arc plates two are provided with through screw holes seven, and the inner sides of the screw holes six and seven are fixed to each other by positioning screws two.

[0010] The present invention is further configured such that: the first annular plate is slidably inserted into the inner side of the first docking groove, and the second annular plate is slidably inserted into the inner side of the second docking groove.

[0011] The present invention is further configured such that: the outer top surfaces of the two arc-shaped positioning blocks are symmetrically provided with through-hole three screw holes, and the outer top surfaces of the annular plate one and the annular plate two are each provided with through-hole four screw holes that are adapted to the screw holes three, and the inner sides of the screw holes three and four screw holes are mutually threaded and fixed by fastening bolts.

[0012] The technical effects achieved by this utility model are as follows: This utility model relates to a concrete pipe pile joint assembly. Through the use of an arc-shaped positioning block, positioning screw one, and fastening bolt, it can quickly lock annular plate one and annular plate two, thereby achieving rapid connection between pipe pile one and pipe pile two. At the same time, it avoids the problems of inconvenience for workers to turn the nut and the long time required to tighten the nut, thus improving its practicality.

[0016] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figure 1 , Figure 3 and Figure 4 As shown, a concrete pipe pile joint assembly includes a pipe pile 1 and a pipe pile 2 detachably connected to the outer top of the pipe pile 1. An annular plate 3 is fixedly provided on the top of the outer peripheral sidewall of the pipe pile 1, and an annular plate 4 is fixedly provided on the bottom of the outer peripheral sidewall of the pipe pile 2. The annular plate 3 and the annular plate 4 are fixedly connected to each other by a connecting assembly 5. The connecting assembly 5 is used to lock the annular plate 3 and the annular plate 4, thereby realizing the rapid docking of the pipe pile 1 and the pipe pile 2.

[0018] like Figure 3 and Figure 4 As shown, the connecting component 5 includes symmetrically formed through arc-shaped grooves 501 on the outer top surface of the annular plate 3, and arc-shaped plates 502 fixed on the outer bottom surface of the annular plate 4 corresponding to the arc-shaped grooves 501. One end of the two arc-shaped plates 502 is slidably inserted into the inner side of the two arc-shaped grooves 501. When docking, the arc-shaped plates 502 are first slidably inserted into the inner side of the arc-shaped grooves 501 to provide a stable alignment effect for subsequent connection.

[0019] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, each of the two arc-shaped plates 502 has a through-hole screw hole on its outer side wall. Arc-shaped positioning blocks 503 are symmetrically fitted onto the outer sides of both arc-shaped plates 502 and annular plates 4. A mating groove 504 is formed at the bottom of the groove 506 of the two arc-shaped positioning blocks 503, and a mating groove 505 is formed at the top of the groove 506. Annular plates 3 and 4 are slidably inserted into the inner side of the mating groove 504 and the inner side of the mating groove 505, respectively. A groove 506 for avoiding the two arc-shaped plates 502 is formed at the center of the concave surface of each of the two arc-shaped positioning blocks 503. A groove corresponding to the screw hole is formed at the center of the outer peripheral side wall of each of the two arc-shaped positioning blocks 503. The system includes a through-hole type screw hole 2. Both screw holes 1 and 2 are threaded together with a positioning screw 507. First, two arc-shaped positioning blocks 503 are fitted onto the outside of annular plates 3 and 4, with annular plate 3 abutting against the inside of the mating groove 504 and annular plate 4 abutting against the inside of the mating groove 505. Two arc-shaped plates 502 abut against corresponding grooves 506, allowing the two arc-shaped positioning blocks 503 to fit against the outer walls of pipe pile 1 and pipe pile 2. Then, the positioning screw 507 is screwed in, threaded from the inside of screw hole 2 into the inside of screw hole 1, thus fixing the two arc-shaped positioning blocks 503 at the joint of pipe pile 1 and pipe pile 2, achieving a rapid docking effect. like Figure 3 , Figure 4 and Figure 5 As shown, two arc-shaped positioning blocks 503 have symmetrical through-hole three screw holes on their outer top surfaces. Annular plate 1 3 and annular plate 2 4 also have through-hole four screw holes on their outer top surfaces that are compatible with screw holes three. The inner sides of screw holes three and four are fixed to each other by fastening bolts 508. By tightening the fastening bolts 508 in sequence so that they pass through the inner sides of screw holes three and four, the arc-shaped positioning blocks 503 are further locked and reinforced with annular plate 1 3 and annular plate 2 4, thereby further improving the locking stability of the joint between pipe pile 1 and pipe pile 2 2.

[0020] like Figure 2 , Figure 3 and Figure 4As shown, pipe pile 1 and pipe pile 2 are fixedly connected to each other by connecting component 2 6. Connecting component 2 6 includes a disc 1 601 on the outer top surface of pipe pile 1 and a disc 2 602 on the outer bottom surface of pipe pile 2. Both the outer top surface of disc 1 601 and the outer bottom surface of disc 2 602 have through-hole screw holes 5. Both the outer top surface of pipe pile 1 and the outer bottom surface of pipe pile 2 have reserved holes that match the screw holes 5. The screw holes 5 and the reserved holes are fixed to each other by positioning screws 2 603. In use, the positioning screws 2 603 are first screwed into the inside of the reserved holes from the screw holes 5, thereby fixing disc 1 601 and disc 2 602 to pipe pile 1 and pipe pile 2 respectively, improving the convenience of subsequent connection.

[0021] like Figure 3 and Figure 4 As shown, symmetrical through-type arc-shaped grooves 604 are formed on the top outer surface of disk 601. Arc-shaped plates 605, adapted to the arc-shaped grooves 604, are fixed on the bottom outer surface of disk 602. The two arc-shaped plates 605 are slidably inserted into the inner sides of the two arc-shaped grooves 604. Screw holes 6, communicating with the arc-shaped grooves 604, are formed on the outer peripheral sidewalls of disk 601. Through-type screw holes 7 are formed on the outer peripheral sidewalls of both arc-shaped plates 605. The six screw holes are threaded together inside the seven screw holes by positioning screws 606. First, the two arc plates 605 are inserted into the inside of the arc groove 604. Then, the positioning screws 606 are screwed into the inside of the six screw holes and inserted into the inside of the seven screw holes, thereby locking the discs 601 and 602. This achieves a quick docking effect between pipe pile 1 and pipe pile 2, reduces the time required for alignment during subsequent docking and locking, and improves practicality.

[0022] The working principle of this utility model is as follows: During use, first, tighten the positioning screw 603 to fix disc 601 and disc 602 onto pipe pile 1 and pipe pile 2 respectively. Then, insert the arc-shaped plate 605 into the inner side of the arc-shaped groove 604, and tighten the positioning screw 606 to lock disc 601 and disc 602, thus initially locking pipe pile 1 and pipe pile 2. Simultaneously, slide the arc-shaped plate 502 into the inner side of the arc-shaped groove 501. Next, place two arc-shaped positioning blocks 503 onto the annular plate 3 and annular plate 4, with annular plate 3 abutting against the inner side of the mating groove 504, and annular plate 4 abutting against the inner side of the mating groove 505. The two arc-shaped plates 502 abut against the corresponding grooves 5. Within 06, by tightening the positioning screw 507, the two arc-shaped positioning blocks 503 are fixed at the joint of pipe pile 1 and pipe pile 2, thereby locking pipe pile 1 and pipe pile 2 a second time. Finally, the fastening bolt 508 is tightened to further lock and reinforce the arc-shaped positioning blocks 503 with the annular plate 3 and annular plate 4.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology.
