In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] See also Figures 1 to 4The present embodiment provides a square pile connection structure, which is used to connect the upper pile body 100 and the lower pile body 200 to form a whole pile, and the square pile connection structure includes a connecting member 1, a matching member 2, a first adapter 3, a second adapter 4 and a locking member 5. The connecting member 1 is arranged on one of the upper pile body 100 and the lower pile body 200. The matching member 2 is arranged on the other of the upper pile body 100 and the lower pile body 200, and the connecting member 1 can be adapted and snap-fitted with the matching member 2. In the present embodiment, the connecting member 1 is arranged on the upper pile body 100, and the matching member 2 is arranged on the lower pile body 2. Of course, in other embodiments, the reverse arrangement can also be made. It should be pointed out that the upper pile body 100 and the lower pile body 200 are also two square piles with the same structure in the prior art, and this embodiment will not be repeated.

[0032] The first adapter 3 is disposed on one of the connecting member 1 and the matching member 2, and the first adapter 3 can partially extend to the first fixing portion 31 outside the upper pile body 100 and the lower pile body 200. The second adapter 4 is disposed on the other of the connecting member 1 and the matching member 2, and the second adapter 4 can partially extend to the second fixing portion 41 outside the upper pile body 100 and the lower pile body 200. In this embodiment, the first adapter 3 is disposed on the upper pile body 100, and the second adapter 4 is disposed on the lower pile body 200. Of course, the reverse arrangement can also be performed in other embodiments.

[0033] It should be noted that the first adapter 3 and the second adapter 4 can be pre-connected with the main reinforcement in the square pile during the process of making the square pile, so as to be cast into one piece, thereby improving the structural strength. In addition, the first adapter 3 and the second adapter 4 can also be installed by screwing. The structures of the first adapter 3 and the second adapter 4 are consistent. The following is an explanation of the structure of the first adapter 3 as an example. In order to improve the convenience of installing the first adapter 3, a through hole is opened on the first adapter 3, and the connecting member 1 can pass through the through hole and be connected to the upper pile body 100, and then the first adapter 3 is penetrated by a bolt to lock the first adapter 3 on the end face of the upper pile body 100. It should be noted that it is necessary to ensure that the head of the bolt is not higher than the plane of the first adapter 3.

[0034] In addition, the locking member 5 is configured to fix the first fixing portion 31 and the second fixing portion 41 as a whole.

[0035] In actual applications, the connecting member 1 and the matching member 2 are respectively arranged on the end surfaces of the upper pile body 100 and the lower pile body 200 for matching, and then the first adapter 3 and the second adapter 4 are respectively arranged on the connecting member 1 and the matching member 2, and then the first adapter 3 and the second adapter 4 are snap-connected, so that the first adapter 3 and the second adapter 4 can be connected as a whole, and finally the locking member 5 is used to fix the first fixing part 31 and the second fixing part 41 as a whole, thereby completing the connection between the upper pile body 100 and the lower pile body 200.

[0036] It can be understood that the upper pile body 100 and the lower pile body 200 can be connected into one by snapping the connecting piece 1 and the matching piece 2, and the first fixing part 31 and the second fixing part 41 are fixed into one by the locking piece 5, which can avoid the problem of easy cracking of welds in the welding connection method used in the prior art, and thus can effectively improve the bending and shear resistance of the entire pile.

[0037] In order to further improve the bending and shearing resistance of the whole pile, a plurality of connecting members 1 are provided, and the number of matching members 2 is set corresponding to the number of connecting members 1. In this embodiment, three connecting members 1 and three matching members 2 are provided.

[0038] In order to improve the convenience of installing the connecting member 1 and the matching member 2 on the pile body, a threaded hole (not shown in the figure) is provided on the upper pile body 100, and the connecting member 1 can be screwed with the threaded hole. This arrangement is more convenient for construction workers to operate. The specific model of the threaded hole can be selected according to the actual application scenario. Similarly, a threaded hole that can be screwed with the matching member 2 is also provided on the lower pile body 200 to improve the assembly speed of the matching member 2.

[0039] Specifically, the matching member 2 is provided with an assembly hole 21, and the connecting member 1 can be partially embedded in the assembly hole 21. In practical applications, the upper pile body 100 and the lower pile body 200 can be positioned by inserting the connecting member 1 into the assembly hole 21. In other words, the upper pile body 100 and the lower pile body 200 are connected. Such a configuration has a simple structure and low use cost.

[0040] In order to improve the convenience of use of the square pile connection structure, the assembly hole 21 is set in a conical shape, and correspondingly, the connecting member 1 includes a conical portion that is similar to the assembly hole 21, so that the connecting member 1 can be embedded in the assembly hole 21 through the conical portion. It can be understood that the conical portion can be easily inserted into the assembly hole 21, thereby helping to improve the convenience of use of the square pile connection structure.

[0041] When the upper pile body 100 and the lower pile body 200 are connected, the first fixing portion 31 on the first adapter 3 and the second fixing portion 41 on the second adapter 4 can fit together to form a fixing. In this embodiment, the locking member 5 includes a locking cavity 51, and the locking cavity 51 can be buckled on the fixing. It can be understood that by buckling the locking cavity 51 on the fixing, the first fixing portion 31 and the second fixing portion 41 can be fixed as one, that is, the first adapter 3 and the second adapter 4 are fixed as one, so that the upper pile body 100 and the lower pile body 200 are connected as one, and the structure is simple.

[0042] It should be noted that, in this embodiment, four first fixing parts 31 are provided, and the four first fixing parts 31 extend to the four sides of the upper pile body 100 respectively. The number of the second fixing parts 41 is set corresponding to the number of the first fixing parts 31, thereby further improving the connection reliability between the upper pile body 100 and the lower pile body 200.

[0043] Furthermore, the cross section of the fixing is set in a trapezoidal shape, and the outer side of the cross section of the fixing is larger than the inner side. In other words, the thickness of the outer side is larger than the thickness of the inner side after the first fixing part 31 and the second fixing part 41 are attached together. The locking cavity 51 is similar in shape to the fixing, and at least one side of the locking cavity 51 is open, so that the locking cavity 51 can be gradually buckled on the fixing from one end of the fixing. In this way, the locking cavity 51 is used to gradually slide and buckle the locking member 5 on the fixing, which is more convenient for construction personnel to operate.

[0044] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
