Description

Technical Field

[0001] The utility model relates to the technical field of prestressed pipe piles, and specifically relates to a positioning member for prestressed pipe piles. Background Technique

[0002] Prestressed pipe piles are foundation piles used in civil engineering and construction engineering, mainly used to bear the weight of buildings and resist foundation settlement. Its characteristic is that prestress is applied in the pile body, so that the pile can better resist bending and compression when bearing load. During construction, two or more piles are often connected by welding, and the connection is usually used to extend the length of the pile and improve the bearing capacity.

[0003] The existing related technologies often have the following defects: during construction, the self-weight of the pipe column may cause the lower end to settle or tilt, resulting in displacement of the pipe column during the connection process. The offset will cause uneven stress at the connection, which may cause some parts to bear excessive loads, reduce the overall bearing capacity, and even lead to structural failure.

[0004] Therefore, the utility model provides a positioning member for prestressed pipe piles. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defect that the pipe column is prone to displacement during the connection process in the existing technology, and a positioning member for prestressed pipe piles is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a positioning member for prestressed pipe piles, including a lower pipe column and an upper pipe column. A positioning structure is provided on the surface of the lower pipe column. The positioning structure includes a frame, the frame sleeves on the arc surface of the lower pipe column, and a plurality of bolts are threadedly connected to the surface of the frame. A groove is opened on the inner wall of the frame, and a plurality of sliders are slidably connected to the inner wall of the groove. A positioning plate is fixedly connected to the surface of the slider, a limiting arm is fixedly connected to the surface of the positioning plate, a pin penetrates through the surface of the limiting arm in a sliding manner, and a plurality of positioning grooves are opened on the arc surface of the frame. The size of the positioning groove is adapted to the size of the pin.

[0007] The effects achieved by the above components are as follows: by setting the positioning structure, it is convenient to position the upper pipe column when welding the upper pipe column to the lower pipe column, so that the upper pipe column and the lower pipe column are in a vertical state, thereby avoiding skew during welding, and ensuring the stability of welding.

[0008] Preferably, a lead screw penetrates through the surface of the positioning plate in a threaded manner, and a positioning block is rotatably connected to one end of the lead screw.

[0009] The effects achieved by the above components are as follows: When welding the upper pipe column and the lower pipe column, a spacing needs to be left between them for convenient welding. The movement of the lead screw will drive the positioning block to move towards the upper pipe column. After the positioning block moves to a suitable position, the positioning block will be inserted into the position between the upper pipe column and the lower pipe column until the positioning block abuts against the surfaces of the upper pipe column and the lower pipe column. The positioning block is convenient for positioning the distance between the upper pipe column and the lower pipe column when welding the upper pipe column and the lower pipe column, so as to facilitate welding the upper pipe column and the lower pipe column together.

[0010] Preferably, two limiting rods slidably penetrate through the surface of the positioning plate, and both of the two limiting rods are fixedly connected to the surface of the positioning block.

[0011] The effects achieved by the above components are as follows: The movement of the positioning block will drive the movement of the limiting rod, and the movement of the limiting rod will move within the positioning plate. The limiting rod restricts the movement path of the positioning block, thereby avoiding the rotation of the positioning block during movement.

[0012] Preferably, a plurality of balls are rotatably connected to one side of the positioning plate.

[0013] The effects achieved by the above components are as follows: When the positioning plate rotates, it will drive the balls to slide along the surface of the upper pipe column, and at the same time, the balls will rotate within the positioning plate. The balls reduce the friction between the positioning plate and the upper pipe column during rotation, thereby facilitating the rotation of the positioning plate.

[0014] Preferably, a spring is sleeved on the arc surface of the bolt, and both ends of the spring are fixedly connected to the bolt and the limiting arm respectively.

[0015] The effects achieved by the above components are as follows: The bolt will be inserted into the positioning groove by the force of the spring contraction. The spring improves the stability of the bolt inserted into the positioning groove, thereby avoiding the bolt from slipping out of the positioning groove due to shaking.

[0016] Preferably, a round rod is fixedly connected to the surface of each of the plurality of positioning plates, and a ring is fixedly connected to one end of each of the plurality of round rods away from the positioning plate.

[0017] The effects achieved by the above components are as follows: The rotation of the ring will drive the rotation of the plurality of round rods, and the rotation of the round rods will drive the rotation of the plurality of positioning plates. The ring is convenient for rotating the plurality of round rods, and further convenient for rotating the plurality of positioning plates simultaneously.

[0018] Preferably, the vertical cross-section of the positioning block is trapezoidal.

[0019] The effects achieved by the above components are as follows: When welding the upper pipe column and the lower pipe column, a spacing needs to be left between them for convenient welding. The positioning block is trapezoidal, so that the positioning block can be used for different spacings.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Referring to Figure 1 as shown, the present utility model provides a technical solution: a prestressed pipe pile positioning member, including a lower pipe column 1 and an upper pipe column 2. A positioning structure 3 is provided on the surface of the lower pipe column 1. By providing the positioning structure 3, it is convenient to position the upper pipe column 2 when welding the upper pipe column 2 to the lower pipe column 1, thereby making the upper pipe column 2 perpendicular to the lower pipe column 1, further avoiding skew during welding and ensuring the stability of welding.

[0029] The following specifically describes the specific settings and functions of its positioning structure 3.

[0030] Referring to Figure 2 - Figure 5As shown in the figure, in this embodiment: The positioning structure 3 includes a frame 301. The frame 301 is sleeved on the arc surface of the lower pipe column 1. A number of bolts 302 are threadedly connected to the surface of the frame 301. A groove 303 is formed in the inner wall of the frame 301. A number of sliders 304 are slidably connected to the inner wall of the groove 303. A positioning plate 305 is fixedly connected to the surface of the slider 304. A limiting arm 306 is fixedly connected to the surface of the positioning plate 305. A pin 307 slidably penetrates through the surface of the limiting arm 306. A number of positioning grooves 308 are formed in the arc surface of the frame 301. The size of the positioning groove 308 is adapted to the size of the pin 307. A lead screw 309 threadedly penetrates through the surface of the positioning plate 305. One end of the lead screw 309 is rotatably connected to a positioning block 310. When welding the upper pipe column 2 and the lower pipe column 1, a spacing needs to be left for convenient welding. The movement of the lead screw 309 will drive the positioning block 310 to move towards the upper pipe column 2. After the positioning block 310 moves to a suitable position, the positioning block 310 will be inserted into the position between the upper pipe column 2 and the lower pipe column 1 until the positioning block 310 abuts against the surfaces of the upper pipe column 2 and the lower pipe column 1. The positioning block 310 is convenient for positioning the distance between the upper pipe column 2 and the lower pipe column 1 when welding the upper pipe column 2 and the lower pipe column 1, so as to facilitate welding the upper pipe column 2 and the lower pipe column 1 together. Two limiting rods 311 slidably penetrate through the surface of the positioning plate 305. Both of the two limiting rods 311 are fixedly connected to the surface of the positioning block 310. The movement of the positioning block 310 will drive the limiting rods 311 to move. The movement of the limiting rods 311 will move on the positioning plate 305. The limiting rods 311 play a role in restricting the movement path of the positioning block 310, thereby preventing the positioning block 310 from rotating when moving. A number of balls 312 are rotatably connected to one side of the positioning plate 305. When the positioning plate 305 rotates, it will drive the balls 312 to slide along the surface of the upper pipe column 2. At the same time, the balls 312 will rotate within the positioning plate 305. The balls 312 play a role in reducing the friction between the positioning plate 305 and the upper pipe column 2 when the positioning plate 305 rotates, thereby facilitating the rotation of the positioning plate 305. A spring 313 is sleeved on the arc surface of the pin 307. Both ends of the spring 313 are fixedly connected to the pin 307 and the limiting arm 306 respectively. The pin 307 will be inserted into the positioning groove 308 by the force of the spring 313 contracting. The spring 313 plays a role in improving the stability of the pin 307 inserted into the positioning groove 308, thereby preventing the pin 307 from falling out of the positioning groove 308 due to shaking. A number of round rods 314 are fixedly connected to the surface of a number of positioning plates 305. One end of a number of round rods 314 away from the positioning plate 305 is fixedly connected to a ring 315. The rotation of the ring 315 will drive a number of round rods 314 to rotate. The rotation of the round rods 314 will drive a number of positioning plates 305 to rotate. The ring 315 is convenient for rotating a number of round rods 314, and further convenient for simultaneously rotating a number of positioning plates 305.The vertical cross-section of the positioning block 310 is trapezoidal. When welding the upper pipe column 2 and the lower pipe column 1, a spacing needs to be left between them for convenient welding. The positioning block 310 is trapezoidal, so that the positioning block 310 can be used for different spacings.

[0031] Working principle: When it is necessary to weld the upper pipe column 2 and the lower pipe column 1 together, first, put the frame 301 on the surface of the lower pipe column 1, and then rotate the bolt 302 on the frame 301. The bolt 302 will move in the frame 301 by means of the thread. The movement of the bolt 302 will move towards the direction close to the lower pipe column 1 until the bolt 302 abuts against the surface of the lower pipe column 1, thereby fixing the frame 301 on the surface of the lower pipe column 1. Then, place the upper pipe column 2 in the middle position among several positioning plates 305. At this time, the upper pipe column 2 will fit on the surface of the ball 312 on the positioning plate 305. Then, pull several bolts 307 at the same time. The movement of the bolt 307 will slide in the limiting arm 306 and gradually slide out of the positioning groove 308. When the bolt 307 moves, the spring 313 will be stretched. When the bolt 307 is disengaged from the positioning groove 308, rotate the ring 315. The rotation of the ring 315 will drive several round rods 314 to rotate. The rotation of the round rods 314 will drive several positioning plates 305 to rotate. The rotation of the positioning plates 305 will drive the slider 304 to slide along the inner wall of the groove 303. When the positioning plates 305 rotate, they will drive the balls 312 to slide along the surface of the upper pipe column 2. At the same time, the balls 312 will rotate in the positioning plates 305. The balls 312 serve to reduce the friction between the rotating positioning plates 305 and the upper pipe column 2, thereby facilitating the rotation of the positioning plates 305. When the positioning plates 305 rotate to the appropriate position, release the bolt 307. The bolt 307 will be inserted into the positioning groove 308 by the force of the spring 313 contracting. The spring 313 serves to improve the stability of the bolt 307 inserted into the positioning groove 308, thereby preventing the bolt 307 from disengaging from the positioning groove 308 due to shaking. When welding the upper pipe column 2 and the lower pipe column 1, a spacing needs to be left between them for convenient welding. Then, rotate the screw rod 309. The rotation of the screw rod 309 will move in the positioning plate 305 by means of the thread. The movement of the screw rod 309 will drive the positioning block 310 to move towards the direction close to the upper pipe column 2. The movement of the positioning block 310 will drive the limiting rod 311 to move. The movement of the limiting rod 311 will move in the positioning plate 305. The limiting rod 311 serves to limit the movement path of the positioning block 310, thereby preventing the positioning block 310 from rotating during movement. After the positioning block 310 moves to the appropriate position, the positioning block 310 will be inserted into the position between the upper pipe column 2 and the lower pipe column 1 until the positioning block 310 abuts against the surfaces of the upper pipe column 2 and the lower pipe column 1. The positioning block 310 serves to facilitate positioning the distance between the upper pipe column 2 and the lower pipe column 1 when welding the upper pipe column 2 and the lower pipe column 1, thereby facilitating welding the upper pipe column 2 and the lower pipe column 1 together.
