Description

Technical Field

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

[0002] Precast pipe piles are a type of prestressed concrete pipe pile, mainly composed of a cylindrical pile body, end plates, and steel hoops. The end plates are disc-shaped structures installed at both ends of the pipe pile, which usually have holes to allow different pipe piles to be connected by bolts. This design allows the pipe piles to be firmly connected to other pipe piles or building structures, ensuring the overall stability of the structure. When connecting different pipe piles, one pipe pile needs to be positioned and installed first, and then another pipe pile is lifted using equipment such as a crane. The pipe pile is then manually pulled to position it. After positioning, the piles are spliced. During splicing, bolts and other structures need to be added into the holes for positioning and to increase the radial bearing strength at the pipe pile connection. Finally, the connection is reinforced by welding.

[0003] However, there are many holes on the end plates. When positioning manually, it is not easy to align multiple holes at the same time. This can easily lead to problems where the holes are not aligned, causing the positioning structures such as bolts to be unable to connect the upper and lower end plates at the same time. Utility Model Content

[0004] The purpose of this utility model is to provide a precast pipe pile structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precast pipe pile structure, including a pipe pile body, with end plates fixedly installed at the top and bottom of the pipe pile body, and an eyelet opened at the top of the end plate, with a positioning pin engaged on the inner wall of the eyelet;

[0006] The eyelet includes a column groove that communicates with the surface of the end plate. A semi-circular groove is formed at the bottom of the column groove. The middle section of the positioning pin is cylindrical, and the upper and lower ends of the positioning pin are semi-circular. The cylindrical part is engaged in the column groove, and the semi-circular part is engaged in the semi-circular groove. The length of the positioning pin is twice the depth of the eyelet. Multiple eyelets are provided and are distributed in a circumferential array on the end plate.

[0007] Furthermore, a threaded groove is provided at the bottom of the semi-circular groove, a threaded post is fixedly installed at the bottom end of the positioning pin, an extension rod is fixedly installed at the top end of the positioning pin, the threaded post is threadedly connected in the threaded groove, and the outer diameter of the extension rod is consistent with the inner diameter of the threaded groove.

[0008] Furthermore, a semi-circular groove 2 is provided at the bottom of the threaded groove, and a semi-circular groove 2 is fixedly installed at the end of the threaded post and extension rod away from the positioning pin, and the semi-circular groove 2 is snapped into the semi-circular groove 2.

[0009] Furthermore, a steel sleeve is fixedly fitted on the outer wall of the pipe pile body. The steel sleeve is welded to the reinforcing bars inside the pipe pile body. Multiple steel sleeves are provided and are distributed at equal intervals on the pipe pile body.

[0010] Furthermore, an installation block is welded to the outer wall of the steel sleeve, and an installation hole one is opened on the outer wall of the installation block. A positioning hole is opened on the outer wall of the installation block, and a connector is threaded to the inner wall of the installation hole one. An installation hole two is opened on the outer wall of the connector.

[0011] Furthermore, a casting pipe is welded to the outer wall of the steel sleeve, and a casting hole is opened on the outer wall of the casting pipe. The casting pipe connects multiple upper and lower steel sleeves, and multiple steel sleeves are provided and distributed in a circumferential array on the steel sleeves.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting the upper and lower ends of the positioning pin into a semi-circular shape, that is, by taking advantage of the fact that the upper and lower ends of the positioning pin are smaller than the middle section used for positioning and bearing radial pressure, it is easier for the upper and lower ends of the positioning pin to be inserted into the hole. When splicing pipe piles, if the position of the holes on the upper and lower pipe piles is offset, as long as the semi-circle can be inserted into the hole, as the upper pipe pile falls, the semi-circle can move the position of the upper pipe pile by abutting against the inner wall of the hole, and automatically align it.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a precast pipe pile structure, including a pipe pile body 1, with an end plate 2 fixedly installed at the top and bottom of the pipe pile body 1, and an eye 3 opened at the top of the end plate 2, with a positioning pin 6 snapped into the inner wall of the eye 3.

[0021] The eyelet 3 includes a column groove 301, which communicates with the surface of the end plate 2. A semi-circular groove 302 is formed at the bottom of the column groove 301. The middle section of the positioning pin 6 is a cylinder 601, and the upper and lower ends of the positioning pin 6 are semi-circles 602. The cylinder 601 is engaged in the column groove 301, and the semi-circles 602 are engaged in the semi-circular groove 302. The length of the positioning pin 6 is twice the depth of the eyelet 3. Multiple eyelets 3 are provided and arranged in a circumferential array on the end plate 2. By... The upper and lower ends of the positioning pin 6 are set in a semi-circular shape. This means that the upper and lower ends of the positioning pin 6 are smaller than the middle section used for positioning and bearing radial pressure, making it easier for the upper and lower ends of the positioning pin 6 to be inserted into the hole 3. This means that if the hole 3 on the upper and lower pipe piles is misaligned during pipe pile splicing, as long as the semi-circle 602 can be inserted into the hole 3, the semi-circle 602 can move the position of the upper pipe pile by abutting against the inner wall of the hole 3 as the upper pipe pile falls, and automatically aligns it.

[0022] The bottom of the semi-circular groove 302 is provided with a threaded groove 4. The bottom end of the positioning pin 6 is fixedly installed with a threaded post 7, and the top end of the positioning pin 6 is fixedly installed with an extension rod 16. The threaded post 7 is threadedly connected in the threaded groove 4. The outer diameter of the extension rod 16 is the same as the inner diameter of the threaded groove 4. By screwing the threaded post 7 at the bottom end of the positioning pin 6 into the threaded groove 4, the positioning pin 6 is fixedly connected to the end plate 2 on the lower pipe pile body 1. Then, the extension rod 16 is inserted into the threaded groove 4 to strengthen the connection.

[0023] The bottom of the threaded groove 4 is provided with a semi-circular groove 2 5. The threaded post 7 and the extension rod 16 are fixedly installed with a semi-circular groove 2 8 at the end away from the positioning pin 6. The semi-circular groove 2 8 is snapped into the semi-circular groove 2 5. The semi-circular groove 2 8 is set to be smaller than the threaded post 7 and the extension rod 16 so that the semi-circular groove 2 8 can be better inserted into the threaded groove 4.

[0024] A steel sleeve 15 is fixedly fitted on the outer wall of the pipe pile body 1. The steel sleeve 15 is welded to the steel bars inside the pipe pile body 1. Multiple steel sleeves 15 are provided and are evenly distributed on the pipe pile body 1 to increase and strengthen the connection of the pipe pile and improve the overall stability.

[0025] The outer wall of the steel sleeve 15 is welded with an installation block 9. The outer wall of the installation block 9 has an installation hole 10 and a positioning hole 11. The inner wall of the installation hole 10 is threaded with a connector 12. The outer wall of the connector 12 has an installation hole 13. The installation block 9 and the installation hole 10 are used to install the external structure on the pipe pile. The connector 12 is used to install the external component through the installation hole 13 when the external component cannot be installed in the installation hole 10.

[0026] A casting pipe 14 is welded to the outer wall of the steel sleeve 15. A casting hole is opened on the outer wall of the casting pipe 14. The casting pipe 14 connects multiple upper and lower steel sleeves 15. Multiple steel sleeves 15 are provided and distributed in a circumferential array on the steel sleeves 15. The casting pipe 14 is used to pour concrete on the outside of the pipe pile body 1.

[0027] Working principle: In use, one pipe pile is first installed in the pipe pile hole. Multiple positioning pins 6 are taken out and inserted into the hole 3. Rotating the positioning pins 6 drives the threaded column 7 to rotate, so that the threaded column 7 is screwed into the threaded groove 4. The other pipe pile is lifted by a crane and positioned by manually pulling the suspended pipe pile. When the positioning pin 6 can be inserted into the hole 3, the crane can be used to move the suspended pipe pile down. When the pipe pile moves down, if the end of the positioning pin 6 contacts the inner wall of the column groove 301 in the hole 3, it will push the suspended pipe pile to move, realizing automatic alignment, until the end plates 2 on the upper and lower pipe piles contact. Then the two end plates 2 are welded to complete the splicing of the pipe piles.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
