Description

Technical Field

[0001] This utility model belongs to the field of pipe pile technology, and in particular relates to a connection structure for prestressed pipe piles. Background Technology

[0002] In the late 1960s, pre-tensioned prestressed concrete pipe piles (PC pipe piles) began production, mainly used for the foundation construction of railway bridge projects; in the 1970s, post-tensioned prestressed concrete pipe piles were developed and produced.

[0003] Publication (Announcement) No. CN221345556U discloses a connection structure for prestressed concrete pipe piles, including a base; a hole is formed in the middle of the base; a connecting column is slidably connected to the middle of the base; multiple sets of the connecting columns are arranged in the hole of the base; an expansion ring is fixedly connected to the top of the connecting column and surrounds the side of the connecting column; in operation, the connecting end of the concrete pipe pile is inserted into the base, and the connecting hole on the concrete pipe pile mates with the connecting column. When the connecting column is inserted into the hole of the concrete pipe pile, the expansion ring also enters the hole. When the connecting column is pulled outward, the expansion ring will lock the contacting concrete, thereby preventing the connecting column from detaching from the hole; this step fixes the connecting column in the connecting hole, reducing the risk of detachment.

[0004] The problem with the existing technology is that when connecting and fixing two sets of pipe piles, the fixed range between the pipe piles is limited, which makes it easy for the pipe piles to tilt when they are too long, making it difficult to fix them and unable to support the connection structure. Therefore, we propose a connection structure for prestressed pipe piles. Utility Model Content

[0005] The purpose of this utility model is to provide a connection structure for prestressed pipe piles to solve the problem mentioned above, where when two sets of pipe piles are connected and fixed, the fixed range between the pipe piles is limited, which leads to the pipe piles being prone to tilting when they are too long, making it inconvenient to fix them and unable to support the connection structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model is implemented as follows: a connection structure for prestressed pipe piles includes a pipe pile. Two sets of fixing frames are movably installed on the outer wall of the pipe pile. One end of the upper surface of the two sets of fixing frames has a sliding groove. An extension plate is slidably installed in the sliding groove. A clamping assembly is fixedly installed on the side wall of the extension plate. Both ends of the clamping assembly are in close contact with the outer wall of the pipe pile. An extension assembly is fixedly installed on the side wall of the two sets of fixing frames. One end of the extension assembly is fixedly installed on the extension plate. An arc-shaped plate is movably installed on the lower surface of the two sets of fixing frames. The arc-shaped plate is in close contact with the outer wall of the pipe pile.

[0008] As a further embodiment of this utility model: the extension assembly includes an extension frame, an electric push rod, a limiting plate, and a limiting rod. The extension frame is fixedly installed on the side wall of the fixed frame, the electric push rod is fixedly installed on the bottom of the extension frame, the limiting plate is fixedly installed on one end of the electric push rod, and one end of the limiting rod is fixedly installed on the limiting plate.

[0009] As a further embodiment of this utility model: the clamping assembly includes a clamping seat, a threaded rod, a motor, a threaded sleeve, and a clamping plate. The clamping seat is fixedly installed on the side wall of the extension plate. A square groove is provided on the clamping seat. The threaded rod is rotatably installed on both ends of the inner wall of the square groove. The threads on the threaded rod are arranged in opposite directions. The motor is fixedly installed on the side wall of the clamping seat. The output shaft of the motor is inserted and connected to the clamping seat. One end of the threaded rod is fixedly installed on the output shaft of the motor. The output shaft of the motor and the threaded rod are coaxially connected.

[0010] As a further embodiment of this utility model: both sets of threaded sleeves are slidably installed at both ends of the threaded rod, and both sets of clamping plates are fixedly installed on the two sets of threaded sleeves.

[0011] As a further embodiment of this utility model: the lower surfaces of the two sets of fixed frames are fixedly mounted on fixed columns, and an electric slide is fixedly mounted on the lower surface of the fixed columns.

[0012] As a further embodiment of this utility model: a fixing rod is fixedly installed on the working slide of the electric slide table, and the side wall of the arc-shaped plate is fixedly connected to one end of the fixing rod.

[0013] As a further embodiment of this utility model: two sets of fixed frame sidewalls are fixedly installed with lead screw sleeves, and two sets of fixed frame sidewalls are fixedly installed with threaded blocks, and the threaded blocks and lead screw sleeves are connected by lead screw threads.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, an extension frame is installed on the side walls of two sets of fixed frames. An electric push rod is fixedly installed at the bottom of the extension frame. The electric push rod is connected to a limiting rod via a limiting plate. One end of the limiting rod is connected to an extension plate that is slidably connected to a groove at one end of the two sets of fixed frames. A clamping assembly is installed on the side wall of the extension plate. When the limiting rod moves, it pushes the extension plate out of the groove and then fixes it through the clamping assembly. This increases the area of ​​fixed support at the pipe pile connection, enhances stability, and prevents the pipe pile from tilting after fixing. A clamping seat is installed on the side wall of the extension plate. Threads are rotatably installed at both ends of the square groove inner wall of the clamping seat. The rod, with one end mounted on the output shaft of the motor, has threads arranged in opposite directions. When the motor rotates, it drives the threads on the rod to rotate in opposite directions, causing the two sets of threaded sleeves sliding on the rod to move the clamping plates inward or outward simultaneously. This clamps and fixes the outer wall of one end of the pipe pile, facilitating support for the pipe pile. Fixed columns are installed on the lower surface of the two sets of fixed frames. The fixed columns are connected to the fixed rods via electric slides, and one end of the fixed rods is connected to an arc-shaped plate. The sliding of the electric slides causes the arc-shaped plate at one end of the fixed rods to move towards the outer wall of the pipe pile, thus supporting the outer wall of the pipe pile.

[0016] 2. In this utility model, screw sleeves and threaded blocks are fixedly installed on the side walls of two sets of fixed frames, and the screw sleeves and threaded blocks are connected by screw threads, which makes it easy to fix the connection of the pipe pile. Attached Figure Description

The extension assembly 12 includes an extension frame 121, an electric push rod 122, a limiting plate 123, and a limiting rod 124. The extension frame 121 is fixedly mounted on the side wall of the fixed frame 2, the electric push rod 122 is fixedly mounted on the inner bottom of the extension frame 121, the limiting plate 123 is fixedly mounted on one end of the electric push rod 122, and one end of the limiting rod 124 is fixedly mounted on the limiting plate 123. The clamping assembly 9 includes a clamping... The system comprises a holder 901, a threaded rod 902, a motor 903, a threaded sleeve 904, and a clamping plate 905. The holder 901 is fixedly mounted on the side wall of the extension plate 6. A square groove is formed on the holder 901. The threaded rod 902 is rotatably mounted on both ends of the inner wall of the square groove. The threads on the threaded rod 902 are arranged in opposite directions. The motor 903 is fixedly mounted on the side wall of the holder 901. The output shaft of the motor 903 is inserted and connected to the holder 901. One end of the threaded rod 902 is fixedly mounted on the motor 905. On the output shaft of 3, the output shaft of motor 903 is coaxially connected to threaded rod 902. Two sets of threaded sleeves 904 are slidably installed at both ends of threaded rod 902. Two sets of clamping plates 905 are fixedly installed on the two sets of threaded sleeves 904. The lower surfaces of two sets of fixed frames 2 are fixedly installed on fixed columns 7. An electric slide table 8 is fixedly installed on the lower surface of fixed column 7. A fixed rod 10 is fixedly installed on the working slide of electric slide table 8. The side wall of arc plate 11 is fixedly connected to one end of fixed rod 10.

A clamping seat 901 is installed on the side wall of the extension plate 6. Threaded rods 902 are rotatably installed at both ends of the square groove inner wall of the clamping seat 901. One end of the threaded rod 902 is mounted on the output shaft of the motor 903. The threads on the threaded rod 902 are arranged in opposite directions. When the motor 903 rotates, it drives the threads on the threaded rod 902 to rotate in opposite directions, causing the two sets of threaded sleeves 904 sliding on the threaded rod 902 to move the clamping plate 905 inward or outward at the same time. This allows the outer wall of one end of the pipe pile 1 to be clamped and fixed, thus facilitating the support of the pipe pile 1. Fixing columns 7 are installed on the lower surface of the two sets of fixing frames 2. The fixing columns 7 are connected to the fixing rod 10 through the electric slide table 8, and one end of the fixing rod 10 is connected to the arc plate 11.

One end of the limiting rod 124 is connected to an extension plate 6 that is slidably connected in a groove at one end of the two sets of fixed frames 2. A clamping assembly 9 is installed on the side wall of the extension plate 6. When the limiting rod 124 moves, it pushes the extension plate 6 out of the groove and fixes it through the clamping assembly 9. This increases the area of ​​fixed support for the connection of the pipe pile 1, enhances stability, and prevents the pipe pile 1 from tilting after fixing. A clamping seat 901 is installed on the side wall of the extension plate 6. Threaded rods 902 are rotatably installed at both ends of the square groove inner wall of the clamping seat 901. One end of the threaded rod 902 is mounted on the output shaft of the motor 903. The threads on the threaded rod 902 are arranged in opposite directions. When the motor 903 rotates, it drives the threads on the threaded rod 902 to rotate in opposite directions, causing the two sets of threaded sleeves 904 sliding on the threaded rod 902 to move the clamping plate 905 inward or outward simultaneously. This clamps and fixes the outer wall of one end of the pipe pile 1, thus facilitating the support of the pipe pile 1. Fixing columns 7 are installed on the lower surface of the two sets of fixing frames 2. The fixing columns 7 are connected to the fixing rod 10 through the electric slide table 8, and one end of the fixing rod 10 is connected to the arc plate 11. The sliding of the electric slide table 8 drives the arc plate 11 at one end of the fixing rod 10 to move towards the outer wall of the pipe pile 1, thereby supporting the outer wall of the pipe pile 1.
