[0002] In the field of building construction, pile foundations are an important type of foundation widely used in various building projects. Precast pipe piles, with their advantages of lower cost, faster construction speed, and easier control over pile quality, occupy a crucial position in pile foundation construction. Whether it's high-rise buildings, bridge projects, or industrial plants, precast pipe piles play an indispensable role, providing stable and reliable support for the building structure.

[0003] With the rapid development of the construction industry and the continuous emergence of various large-scale construction projects, higher requirements have been placed on the efficiency and quality of precast pipe pile construction. As a key link in the construction process of precast pipe piles, the connection effect of the pipe piles directly affects the stability and bearing capacity of the entire pile foundation, and thus relates to the quality and safety of the construction project.

[0004] Currently, the commonly used methods for connecting precast pipe piles include welding and flange bolt connections. However, in actual use, although welding has a certain connection strength, it requires specialized equipment and personnel, the preparation work is cumbersome, the welding is time-consuming, and it affects the progress of the project. Flange bolt connections require flanges at both ends of the pipe pile, and the installation, alignment, and tightening of bolts are time-consuming, resulting in low connection efficiency.

A fixing component is provided on the upper surface of the pipe pile 1, and the fixing component can quickly install the assembly mechanism on the pipe pile 1 and the pipe pile 2.

[0037] The fixing component includes a second mounting plate 32, which is disposed on the upper surface of the first pipe pile 1, and the lower surface of the second mounting plate 32 is attached to the upper surface of the first pipe pile 1. The lower surface of the second pipe pile 2 is provided with a first mounting plate 31, and the upper surface of the first mounting plate 31 is attached to the lower surface of the second pipe pile 2. The second mounting plate 32 is provided with an assembly mechanism for connecting the first pipe pile 1 and the second pipe pile 2.

[0038] Reference Figure 2 - Figure 4The assembly mechanism includes a quick-connect assembly and a positioning assembly for quickly connecting mounting plate 1 31 and mounting plate 2 32. The quick-connect assembly includes a locking block 41, which is slidably connected to the upper surface of mounting plate 2 32. A slider 42 is fixedly connected to the lower surface of the locking block 41. The front surfaces of the locking block 41 and the slider 42 are flush. The middle position of the lower surface of the slider 42 is hollowed out. One end of a compression spring 46 is fixedly connected to the inner wall of the bottom end of mounting plate 2 32. The other end of the compression spring 46 is fixedly connected to a pressure plate 45. The pressure plate 45 and mounting plate 2... 32. An elastic connection is provided. A movable block 43 is fixedly connected to the upper surface of the pressure plate 45. A positioning rod 44 is fixedly connected to the outer wall of the movable block 43, and the positioning rod 44 is located at the top of the outer wall of the movable block 43. The pressure plate 45, the movable block 43 and the positioning rod 44 will move synchronously. The inner wall of the slider 42 is provided with a groove 402 corresponding to the positioning rod 44. The lower surface of the mounting plate 31 is provided with a slot 401. There are four sets of slots 41, 42, 43, 44 and slot 401, which are arranged in a circular array with the center of the pressure plate 45 as the origin. The positioning component includes a connecting block 51, which is slidably connected to the front surface of the mounting plate 32 and the rear surface of the connecting block 51 is fixedly connected to the front surface of the pressure plate 45. A pressure block 52 is fixedly connected to the front surface of the connecting block 51. The pressure block 52 and the connecting block 51 move synchronously. The pressure block 52 is designed as an L-shape for easy pressing. A positioning bolt 53 is rotatably connected to the front surface of the pressure block 52.

[0039] Reference Figure 2 - Figure 4 The lower surface of mounting plate 31 and the upper surface of mounting plate 32 are in contact to maintain stability. The rear end of the upper surface of the locking block 41 is set as an inclined surface that will cause the locking block 41 to shift when squeezed. When the inclined surface is squeezed, the locking block 41 will move towards the edge of mounting plate 32. The slider 42 is slidably connected to the inner wall of mounting plate 32. The locking block 41 and slider 42 in the front position slide in the back-and-forth direction. The pressure plate 45 is slidably connected to the inner wall of mounting plate 32 and is in contact with the inner wall of mounting plate 32. The pressure plate 45 moves longitudinally. When the pressure plate 45 moves downward, it will squeeze and compress the spring 46. The positioning rod 44 has a reaction force, with its left and right ends distributed through the left and right surfaces of the moving block 43. The positioning rod 44 is slidably connected to the inner wall of the slide groove 402. The slide groove 402 is inclined in a way that will cause the corresponding slider 42 to move when squeezed, with the front higher than the back. When the positioning rod 44 moves longitudinally, it will squeeze the slide groove 402, causing the slider 42 and the locking block 41 to move. The initial position of the positioning rod 44 is located at the front of the slide groove 402. The locking block 41 is inserted into the inner wall of the locking groove 401 to limit the mounting plate 31, so that the mounting plate 31 and the mounting plate 32 are connected together.

[0040] Reference Figure 2 - Figure 4The positioning bolt 53 is threaded onto the front surface of the mounting plate 2 32, which can limit the pressure block 52 and prevent accidental contact.

[0041] Reference Figure 2 - Figure 4 The fixing component also includes a positioning block 33, which is fixedly connected to the lower surface of the second mounting plate 32. The front surface of the positioning block 33 is rotatably connected with a fixing bolt 34. The bottom end of the rear surface of the positioning block 33 is set as an inclined surface to facilitate positioning. Multiple sets of positioning blocks 33 and fixing bolts 34 are provided and are evenly distributed below the second mounting plate 32 and above the first mounting plate 31. The fixing bolts 34 are threadedly connected to the front surface of the first pipe pile 1. The fixing bolts 34 installed on the positioning block 33 above the first mounting plate 31 are threadedly connected to the front surface of the second pipe pile 2.

[0042] Working principle: Before installation, the second mounting plate 32 is installed on the upper surface of the first pipe pile 1 through the positioning block 33 and the fixing bolt 34, and the first mounting plate 31 is installed on the lower surface of the second pipe pile 2 through the positioning block 33 and the fixing bolt 34. The inclined surface at the bottom of the rear surface of the positioning block 33 facilitates positioning.

[0043] When connecting pipe pile 1 and pipe pile 2, pipe pile 2 is first hoisted above pipe pile 1, so that the lower surface of mounting plate 31 gradually approaches and fits against the upper surface of mounting plate 32. During this process, the lower surface of mounting plate 31 contacts the inclined surface of the upper surface of the locking block 41. As the two continue to approach, the inclined surface is compressed, forcing the locking block 41 to move towards the edge of mounting plate 32. When the locking block 41 moves, it drives the slider 42, which is fixedly connected to it, to slide on the inner wall of mounting plate 32.

[0044] When the slider 42 slides, it will drive the slide groove 402 to move and squeeze the positioning rod 44, which will in turn cause the positioning rod 44, the moving block 43 and the pressure plate 45 to move downward. The downward moving pressure plate 45 will squeeze the compression spring 46 to generate a reaction force.

[0045] When mounting plate 1 31 and mounting plate 2 32 are fully attached, the compression spring 46 will push the positioning rod 44, the moving block 43 and the pressure plate 45 upward. When the positioning rod 44 moves upward, it will squeeze the slide groove 402, causing the slider 42 and the locking block 41 to move in the opposite direction. The locking block 41 will be inserted into the locking groove 401, thereby limiting the mounting plate 1 31 and mounting plate 2 32 to achieve a quick connection, and initially fixing pipe pile 1 and pipe pile 2 together.

[0046] Then, use the positioning bolt 53 to fix the pressure block 52 to fix the device. When it needs to be disassembled later, unscrew the positioning bolt 53, then press the pressure block 52 down to move the pressure plate 45 down, which in turn moves the positioning rod 44 and the moving block 43 down. The positioning rod 44 will squeeze the slide groove 402 to move the slider 42 and the locking block 41 toward the edge of the mounting plate 32. The locking block 41 will disengage from the locking groove 401 and release the limit.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
