DETAILED DESCRIPTION
[0033] The application will be further described below in conjunction with the accompanying Figure 1 to Figure 4 make further detailed description of the present application.
[0034] The prior art needs to use welding to connect the pipe piles, which is a long process and requires experienced workers, otherwise, joint defects may occur during welding, resulting in insufficient structural strength or easy leakage.
[0035] Therefore, there is an urgent need for a scheme to quickly connect two precast concrete pipe piles 1, avoiding the cumbersome process of welding two pipe piles 1 as in the prior art.
[0036] A pipe pile assembly that can be quickly assembled and disassembled is arranged between two pipe piles 1 to be connected, which includes a connecting pipe base 2 and a connecting socket 3, both of which are connected to one end of the corresponding pipe pile 1. Generally, the end provided with the connecting pipe base 2 is located below, and the pipe pile 1 provided with the connecting socket 3 is butted with the lower pipe pile 1 along the axial direction from top to bottom.
[0037] Specifically, the connecting pipe base 2 is connected to the end of the pipe pile 1, and the connecting pipe base 2 includes a connecting pipe 21, a connecting sleeve 22, and an adapter ring 23.
[0038] The connecting pipe 21 is fixed to the steel structure of the pipe pile 1 through the connecting disc 24. The fixing mode can be welding, bolt connection, etc. After fixing, the concrete part of the pipe pile 1 is poured, so as to improve the stability of the connection and the structural strength. The connecting disc 24 serves as a fixing piece between the connecting pipe 21 and the steel structure of the pipe pile 1, and ensures the firm connection between the connecting pipe 21 and the pipe pile 1. The connecting strength between the connecting pipe 21 and the pipe pile 1 is improved, so that the whole pipe pile 1 assembly is more stable when bearing external force. The outer diameter of the connecting disc 24 is larger than that of the connecting pipe 21, and the two are coaxial. The middle part of the connecting disc 24 can be penetrated to form a through hole, so that the whole structure of the pipe pile 1 remains a hollow structure.
[0039] The adapter ring 23 is coaxially connected to the outer wall of the connecting pipe 21, and the adapter ring 23 slides along the axial direction of the connecting pipe 21. A plurality of protrusions 231 are arranged on the inner wall of the adapter ring 23 at intervals, and the protrusions 231 are rectangular blocks. A plurality of grooves 211 are arranged on the outer wall of the connecting pipe 21 at intervals along the length direction, and the cross section of the groove 211 corresponds to the protrusion 231. The protrusion 231 is slidingly connected in the groove 211. The design of the protrusion 231 and the groove 211 enables the adapter ring 23 to slide along the axial direction of the connecting pipe 21 while maintaining a stable connection relationship. The rotation of the adapter ring 23 is limited, so that the adapter ring 23 can only slide along the axial direction of the connecting pipe 21. At the same time, it is ensured that the adapter ring 23 will not be separated from the connecting pipe 21 when the connecting sleeve 22 rotates, thereby improving the safety and reliability of the whole pipe pile 1 assembly.
[0040] The connecting sleeve 22 is coaxially and rotatably connected to the adapter ring 23. An annular adapter groove 221 is formed in the inner wall of one end of the connecting sleeve 22, and the adapter ring 23 is rotatably connected in the adapter groove 221, so that the connecting sleeve 22 can rotate relative to the adapter ring 23. An inner thread 222 is arranged on the inner wall of the other end of the connecting sleeve 22. The connecting sleeve 22 can slide together with the adapter ring 23 and can rotate around its own axis.
[0041] The connecting socket 3 is connected to the end of another pipe pile 1, and the connecting socket 3 comprises a plug column 31 and a butt column 32.
[0042] The butt column 32 is fixed to the steel structure of the pipe pile 1 at one end, and the fixing mode can be welding, bolt connection, etc. After fixing, the concrete part of the pipe pile 1 is poured, so as to improve the stability of the connection and the structural strength. The other end of the butt column 32 is coaxially connected to the plug column 31, and the plug column 31 extends outward. The plug column 31 and the butt column 32 can also be penetrated to form through holes along the axis, so that the whole structure of the pipe pile 1 remains a hollow structure.
[0043] The insertion post 31 can be inserted into the connecting pipe 21 in the axial direction, and the insertion post 31 is in clearance fit with the connecting pipe 21 (the diameter of the insertion post 31 can be equal to or slightly smaller than that of the connecting pipe 21). The outer diameter of the counter insertion post 32 is the same as that of the connecting pipe 21. Further, the outer edge of the end of the insertion post 31 is provided with a chamfer 311, which is annular. By providing the chamfer 311, when the insertion post 31 is relatively inserted into the connecting pipe 21, the insertion post 31 is more easily inserted into the connecting pipe 21. At the same time, the problem of damage to the connecting pipe 21 caused by excessive insertion resistance is reduced. The outer wall of the counter insertion post 32 is provided with external threads 321, and the connecting sleeve 22 is threadedly connected with the counter insertion post 32 through the external threads 321 and internal threads 222. When the connecting sleeve 22 is slid to abut against the counter insertion post 32, the connecting sleeve 22 can be rotated to make the internal threads 222 and the external threads 321 fit, and the connecting sleeve 22 is continuously rotated until it is fastened, thereby completing the connection between the connecting sleeve 22 and the counter insertion post 32, and the two pipe piles 1 are fixed. In this way, a quick assembly and disassembly scheme is provided, and the efficiency of the pipe pile 1 assembly is improved. At the same time, due to the movement of the connecting sleeve 22 when connecting the counter insertion post 32, the connecting sleeve 22 can pass over the plane where the two pipe piles 1 are connected, thereby providing shielding for the joint of the pipe piles 1 and improving the sealing performance of the joint.
[0044] Further, the outer wall of the connecting pipe 21 is circumferentially provided with a sliding groove 212. The sliding groove 212 is provided with an elastic member 213, which is a spring and is sleeved in the sliding groove 212 of the connecting pipe 21. The inner wall of the connecting sleeve 22 is provided with a sliding ring 223, which is slidingly connected in the sliding groove 212. The elastic member 213 makes the sliding ring 223 always have a tendency to move away from the direction of the connecting disc. The elastic member 213 is only connected with the inner wall of the sliding groove 212 and is not connected with the sliding ring 223. The provision of the elastic member 213 makes the connecting sleeve 22 always have a tendency to slide outward, thereby facilitating the operation of the connecting sleeve 22 and saving labor. At the same time, the design of the elastic member 213 and the sliding groove 212 and the sliding ring 223 makes the connecting sleeve 22 be able to maintain a certain tension when rotating, thereby being more tightly threadedly connected with the counter insertion post 32. The connection tightness between the connecting sleeve 22 and the counter insertion post 32 is enhanced, thereby preventing the problem of connection failure caused by looseness.
[0045] Further, the connecting pipe 21 is spaced apart from the end of the connecting disc in the vertical axial direction and is provided with a plurality of limiting grooves 214. The limiting grooves 214 are slidably connected with limiting pins 4. A plurality of insertion holes 312 are formed in the outer wall of the insertion column 31 and can be inserted by the corresponding limiting pins 4 after sliding. The design of the limiting pins 4 and the limiting grooves 214 makes the insertion column 31 be locked by the limiting pins 4 after being inserted into the connecting pipe 21, and the stability of the connecting sleeve 22 during rotation is ensured. Further, one end of the limiting pin 4 can extend out of the outer wall of the connecting pipe 21, and the end is a hemispherical structure. The outer wall of the limiting pin 4 is provided with a convex ring 41. The connecting pipe 21 is provided with a space groove 215 on the inner wall of the limiting groove 214, which is slidably connected with the convex ring 41. Further, one end of the limiting pin 4 can extend into the inner wall of the connecting pipe 21, and the end is a hemispherical structure. The design of the hemispherical structure of the end of the limiting pin 4 and the convex ring 41 makes the limiting pin 4 slide more smoothly, and the convex ring 41 can prevent the limiting pin 4 from falling out of the limiting groove 214. The sliding stability and reliability of the limiting pin 4 are improved, and the smooth connection of the pipe pile 1 assembly is ensured.
[0046] The implementation principle of the pipe pile assembly according to the embodiment of the present application is as follows:
[0047] By setting the connecting pipe seat 2 and the connecting socket 3, the two pipe piles 1 to be connected can be conveniently connected and disassembled by threaded connection. The connecting pipe seat 2 includes a connecting pipe 21, a connecting sleeve 22 and an adapter ring 23. The design of the adapter ring 23 and the connecting sleeve 22 allows the connecting sleeve 22 to rotate on the adapter ring 23, and then be screwed with the butt joint column 32 of the connecting socket 3.
[0048] The above are the preferred embodiments of the present application, but not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
