Description

Technical Field

[0001] This application relates to the technical field of pipe piles, and particularly to a pipe pile joint. Background Art

[0002] During the process of building construction, it is often necessary to bury concrete pipe piles underground to provide stable foundation support for buildings. These concrete pipe piles are usually prefabricated in factories and then transported to the construction site. At the construction site, workers use welding technology to connect the upper and lower sections of the concrete pipe piles to form a complete pile structure. However, this traditional connection method has obvious problems: First, the welding process itself takes a certain amount of time, which directly affects the overall construction progress and results in a relatively slow construction speed; Second, welding operations require not only professional technicians but also corresponding welding equipment and materials, which undoubtedly increases the construction cost. In addition, some safety hazards may occur during the welding process, such as welding sparks may cause accidents such as fires, and there may also be potential quality problems at the welded joints, affecting the stability and durability of the entire structure. Therefore, technicians in this field urgently need to develop a pipe pile joint that can be applied to the connection of pipe pile end plates to meet the actual application requirements. Summary of the Utility Model

[0031] In an embodiment of the present application, as Figures 1 to 9 shown, a pipe pile joint includes a connecting housing 1 that can be disposed on the pipe pile. A receiving cavity 101 is formed in the connecting housing 1. The pipe pile joint further includes two clamping blocks 2 disposed opposite to each other in the receiving cavity 101, an elastic member 3 disposed in the receiving cavity 101 and outside the clamping blocks 2, and a connecting pin 4 with one end connectable to another pipe pile and the other end connected between the two clamping blocks 2.

[0032] Through the combination of the connecting housing 1, the clamping blocks 2, the elastic member 3, and the connecting pin 4 in the present application, a stable connection between the pipe piles is achieved. Under the action of the elastic member 3, the clamping blocks 2 can firmly lock the connecting pin 4, thereby ensuring that the pipe piles are not easily separated when subjected to external forces, greatly enhancing the strength and stability of the connection. Furthermore, under extreme weather or geological conditions, the pipe piles are not easily fractured or detached, so as to maximize the safety of the overall structure, which is particularly important for engineering projects that need to bear huge loads.

[0033] Further, first clamping teeth 21 are provided on the opposite surfaces of the two clamping blocks 2, and first guiding portions 22 located above the first clamping teeth 21 are also provided on both of them;

[0034] A second clamping tooth portion 41 adapted to the first clamping tooth portion 21 is provided at the other end of the connecting pin 4, and a second guiding portion 42 located below the second clamping tooth portion 41 is also provided.

[0035] A plurality of first clamping teeth 211 arranged from top to bottom and inclined downward are provided on the first clamping tooth portion 21, and a first card slot 212 is provided between two adjacent first clamping teeth 211;

[0036] A plurality of second clamping teeth 411 arranged from top to bottom and inclined upward are provided on the second clamping tooth portion 41, and a second card slot 412 is provided between the two second clamping teeth 411;

[0037] The second clamping teeth 411 are clamped in the first card slots 212, and the first clamping teeth 211 are clamped in the second card slots 412. The purpose is to form a one-way clamping and locking effect, thereby effectively avoiding the occurrence of loosening phenomena.

[0038] Furthermore, spacing protrusions 1011 protruding toward the middle are provided on the front and rear side walls inside the receiving cavity 101 for spacing the two clamping blocks 2. The purpose is to space the two clamping blocks 2, so as to appropriately reduce the downward insertion force when the connecting pin 4 is inserted downward between the two clamping blocks 2.

[0039] Further, the elastic member 3 includes an initial elastic compression spring 31 and a spring force adjustment compression spring 32 sleeved inside the initial elastic compression spring 31, and the spring force of the spring force adjustment compression spring 32 is less than that of the initial elastic compression spring 31. In this application, the initial elastic compression spring 31 is sleeved with the spring force adjustment compression spring 32, so that the elastic extrusion force on the clamping block 2 can be adjusted more conveniently.

[0040] Further, two opposite screwing positions 43 are provided in the middle of the connecting pin 4, and the purpose is to facilitate the screwing of the connecting pin 4.

[0041] Further, a connecting thread 44 is provided on one end of the connecting pin 4 and located above the screwing position 43. In this application, by designing the connecting thread 44, the connecting pin 4 can be conveniently thread-connected to the end plate of the upper section of the pipe pile first. Then, when the upper section of the pipe pile is erected and connected to the lower section of the pipe pile, the connecting pin 4 can be directly inserted and clamped between the two clamping blocks 2 under the construction force, so as to complete the connection work.

[0042] Further, the pipe pile joint further includes an upper cover 5 provided above the connecting pin 4. The purpose is to protect the upper end of the connecting pin 4.

[0043] As described above, an implementation manner is provided in combination with specific content, and it is not considered that the specific implementation of this application is only limited to these descriptions. Any method, structure, etc. that is similar or identical to this application, or any technical deduction or replacement made under the premise of the concept of this application, should be regarded as the protection scope of this application.
