Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe pile connection, in particular to a prestressed concrete pipe pile connection structure. Background Art

[0002] Concrete pipe piles are the foundation when building a house. When the geological conditions are bad and the bearing capacity of the foundation is small, pile foundations must be used. The piles are driven into the ground one by one to transfer the weight of the building above to the lower soil layer with high bearing capacity through the pile foundation. Concrete pipe piles are mainly divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles.

[0003] The patent with the patent authorization announcement number CN212452599U discloses a concrete pipe pile, including a pipe pile outer sleeve and a pipe pile inner pipe. The pipe pile outer sleeve includes a sleeve shell, a circular hole and a thread. Circular holes are opened on the left and right sides of the lower surface of the sleeve. A thread is opened on the inner wall of the circular hole. A pointed cone is arranged below the circular hole. The lower end of the pointed cone is a pointed tip. A threaded column is fixedly connected to the upper surface of the pointed cone. The upper end of the threaded column is inserted into the interior of the circular hole.

[0004] Although the above patent can insert the concrete pipe pile into the target position by setting a pointed cone, there are still some shortcomings in actual use. For example, when the length of a section of concrete pipe pile is not enough and an additional pipe pile is needed, the connecting pipe of the lower section of the pipe pile is threadedly connected with the pipe wall of the upper section of the pipe pile through the connecting pipe and the threaded structure opened thereon to complete the connection. The concrete pipe piles connected by a simple threaded connection method are prone to loosening under alternating loads, causing the two sections of concrete pipe piles to separate from the upper and lower directions, thereby failing to ensure the stability of the concrete pipe pile connection.

[0005] Therefore, a prestressed concrete pipe pile connection structure is particularly needed to solve the problems existing in the prior art. Utility Model Content

[0006] In order to overcome the shortcomings of the existing patents that the concrete pipes for connecting piles using a simple threaded connection method are prone to loosening under alternating loads, resulting in the two sections of concrete pipe piles being separated from the upper and lower directions and being unable to continue to be connected, thereby failing to ensure the stability of the concrete pipe pile connection, the utility model provides a prestressed concrete pipe pile connection structure.

[0007] The utility model is realized through the following technical approaches: a prestressed concrete pipe pile connection structure, comprising a concrete pipe pile, a connecting plate, a casing and a mounting plate, wherein the ends of two sections of concrete pipe piles close to each other are fixedly connected with the connecting plate, a casing is placed between the two sections of concrete pipe piles, the casing is fixedly connected with the mounting plate, and also comprises a latch, a side of the two connecting plates contacting each other is provided with symmetrically distributed first plug holes, two adjacent first plug holes jointly form a rhombus groove, a rhombus-shaped latch is fixedly connected to the arc-shaped inner wall of the casing, and the latch is plugged with the corresponding two first plug holes.

[0008] Optionally, the thickness of the plug is consistent with the hole depth of the first plug hole.

[0009] Optionally, a plug plate is further included, which is fixedly connected to the connecting plate, and second plug holes are provided at the ends of the two sections of concrete pipe piles that are close to each other, and the plug plate is plugged into the corresponding second plug holes.

[0010] Optionally, a sealing ring is further included, the casing is connected with the sealing ring, and the sealing ring is in close contact with the concrete pipe pile.

[0011] Optionally, it also includes a collar, a second fixing plate, a hexagonal bolt and a first fixing plate, and the ends of the two sections of concrete pipe piles close to each other are butt-jointed with symmetrically distributed collars, and the collars are fixedly connected with symmetrically distributed second fixing plates, and a hexagonal bolt is threadedly connected between two adjacent second fixing plates, so that the collar is fixed to the concrete pipe pile, and the collars are fixedly connected with symmetrically distributed first fixing plates, and another two hexagonal bolts are threadedly connected between two adjacent first fixing plates.

[0012] Optionally, the hexagonal bolt is provided with a rubber pad for increasing friction at one end of the hexagonal block, and the rubber pad is in contact with the first fixing plate or the second fixing plate.

[0013] From the above description of the structure of the utility model, it can be seen that the design starting point, concept and advantages of the utility model are: 1. By setting a pin, the two sleeves are placed between the two sections of concrete pipe piles, and then the pins are inserted into the diamond grooves to connect the two connecting plates together, so as to achieve a good connection effect, avoid the two sections of concrete pipe piles from separating from the upper and lower directions when the two sleeves are loose, and ensure the stability of the concrete pipe pile connection.

[0014] 2. By setting the collar, the second fixing plate, the hexagonal bolts and the first fixing plate, the two adjacent collars are connected and fixed on the concrete pipe piles using the hexagonal bolts, and the two adjacent first fixing plates are connected together to reinforce the two sections of concrete pipe piles, thereby improving the stability of the connection between the two sections of concrete pipe piles.
