Referring to fig. 2, the lower end of the connector 1 passes through the lower end plate 201 and is embedded in the lower section pile 200, and the upper end of the connector 1 passes through the upper end plate 101 and is embedded in the upper section pile 100. Referring to fig. 3, the connector 1 is provided with a limiting hole 11. Be provided with guide slot 31 on the upper segment stake 100, guide slot 31 extends along the horizontal direction, and upper end plate 101 closing cap is in the notch of guide slot 31, and locating part 2 sets up in guide slot 31 to have dodge position and locking position, locating part 2 can be by dodging the position translation to the locking position.
When connecting the upper section pile 100 and the lower section pile 200, the lower end of the connecting member 1 is first inserted into the lower section pile 200. At this time, the limiting member 2 is located at the avoiding position, and can avoid the passage of the connecting member 1 extending into the upper pile 100, so that the connecting member 1 can pass through the guiding groove 31 and be smoothly embedded into the upper pile 100. Subsequently, the limiting piece 2 translates from the avoiding position to the locking position so as to penetrate through the limiting hole 11 of the connecting piece 1, thereby locking the connecting piece 1, and at the moment, the upper section pile 100 cannot horizontally move relative to the lower section pile 200 and cannot vertically move, so that the butt joint and fixation of the upper section pile 100 and the lower section pile 200 are realized.
Compared with the construction mode of connecting the upper section pile 100 and the lower section pile 200 by welding in the prior art, the pipe pile joint can conveniently and rapidly connect the upper pipe pile and the lower pipe pile adjacently without welding procedures, so that the construction steps are simplified, the overall construction quality is improved, and the construction cost is reduced.
The upper end plate 101 and the lower end plate 201 are usually made of steel plates, the upper section pile 100 and the lower section pile 200 are formed by concrete pouring, before pouring, the upper end plate 101 and the lower end plate 201 are arranged on the framework structures of the upper section pile 100 and the lower section pile 200, after pouring and forming, the concrete of the upper section pile 100 and the upper end plate 101 are formed into a whole, and the lower section pile 200 and the concrete and the lower end plate 201 are formed into a whole.
An insertion hole 32 communicating with the guide groove 31 is provided in the upper section pile 100, and the insertion hole 32 is used for penetrating the connecting piece 1, that is, the upper end of the connecting piece 1 penetrates through the guide groove 31 and extends into the insertion hole 32.
Referring to fig. 1 and 2, the upper section pile 100 is embedded with a mounting box body 3, and the mounting box body 3 is made of a metal material. Because the upper pile 100 made of concrete is inconvenient to form the guide groove 31 and the hole allowing the connecting piece 1 to penetrate (i.e. the embedded hole 32), the installation box body 3 made of metal material is arranged inside the upper pile 100, and the guide groove 31 and the embedded hole 32 are formed on the installation box body 3, so that the operation is more convenient and the implementation is easier. Optionally, the mounting box 3 is made of steel material.
Illustratively, as with the upper end plate 101, the mounting box 3 may be integrally formed with the concrete structure of the upper section pile 100 at the stage of casting the upper section pile 100.
Referring to fig. 2, an elastic stopper 4 is connected to the top wall of the insertion hole 32, and the elastic stopper 4 can protrude out of the insertion hole 32 to stop the stopper 2 at the escape position so that the connector 1 passes through the guide groove 31 and protrudes into the insertion hole 32. During the extension of the connecting element 1 into the insertion hole 32, the connecting element 1 compresses the elastic stop 4 to release the stop 2. When the connecting piece 1 moves to the position where the limiting hole 11 is aligned with the limiting piece 2, the limiting piece 2 can penetrate into the limiting hole 11.
Specifically, referring to fig. 2, the elastic stopper 4 includes a first elastic member 41 and a stopper 42 connected, one end of the first elastic member 41 remote from the stopper 42 is connected to the top wall of the insertion hole 32, and the stopper 42 at least partially protrudes out of the insertion hole 32 to stop the stopper 2. Referring to the orientation shown in fig. 2, the first elastic member 41 is naturally configured such that the right side of the stopper 42 serves to stop the stopper 2, and the left side of the stopper 42 can be brought into contact with the wall surface of the mounting case 3 to ensure that the stopper 2 is stably at the escape position.
Illustratively, the first elastic member 41 is a spring, and the stopper 42 is a cylindrical steel plate having a diameter slightly smaller than that of the insertion hole 32.
Referring to fig. 2, a second elastic member 5 is disposed between the limiting member 2 and the groove wall of the guide groove 31, and the expansion direction of the second elastic member 5 is the same as the translation direction of the limiting member 2, and the limiting member 2 can translate from the avoiding position to the locking position under the action of the elastic force of the second elastic member 5. When the stopper 42 stops the stopper 2, the second elastic member 5 is in a compressed state, and when the limiting hole 11 of the connecting member 1 is aligned with the stopper 2, the stopper 2 can move leftwards under the elastic action of the second elastic member 5 so as to penetrate into the limiting hole 11. The second elastic member 5 is illustratively a spring.
Referring to fig. 5, 6 and 7, the limiting member 2 includes a limiting body 21 and a protruding portion 22 protruding from the limiting body 21, wherein the cross section of the limiting body 21 and the cross section of the protruding portion 22 are rectangular, and the cross section of the protruding portion 22 is smaller than the cross section of the limiting body 21. Correspondingly, referring to fig. 4, the guide groove 31 includes a large groove section 311 cooperating with the limit body 21 and a small groove section 312 cooperating with the boss 22, the cross sections of the large groove section 311 and the small groove section 312 are also rectangular, and the cross section area of the small groove section 312 is smaller than the cross section area of the large groove section 311. The two opposite sides of the small groove section 312 on the mounting box body 3 are respectively provided with a stop step 313, and the stop step 313 is used for stopping one side of the elastic stop piece 4, which is opposite to the limiting piece 2.
In this embodiment, the first elastic member 41 is in a natural state, and the stop member 42 below the first elastic member extends out of the insertion hole 32, and the top surface of the first elastic member is flush with the bottommost end of the insertion hole 32. At this time, the left side of the stopper 42 is limited by the stop steps 313 at both sides of the small groove section 312, so that the stopper 42 can reliably stop the stopper 2 at the right side, and the stopper 2 is ensured to be at a position of avoiding the connecting member 1.
Further, the protruding portion 22 is protruding at the middle position of the top of the limiting body 21, and the small groove section 312 is located at the middle position of the top of the large groove section 311.
Referring to fig. 2, the lower section pile 200 is embedded with a fixing member 6, the fixing member 6 is located below the lower end plate 201, and the lower end of the connecting member 1 passes through the lower end plate 201 and is in threaded connection with the fixing member 6, so that the connection is firm and convenient.
