[0029] like Figure 1-Figure 3 As shown, this embodiment provides a connecting member, which includes a sleeve member 1 and an extension member 2. The sleeve member 1 is provided with a connecting groove 11 extending along a first direction, and the connecting groove 11 is used to connect the foundation steel bar 100. The extension member 2 is connected to the sleeve member 1 and is coaxially arranged with the sleeve member 1. The extension member 2 is pre-embedded in the pile body 200 and is extended along the first direction. The extension member 2 is used to connect to the main reinforcement 201 of the pile body 200.

[0030] In this embodiment, the sleeve member 1 is provided with a connection groove 11 extending along the first direction, and the connection groove 11 is used to connect the foundation steel bar 100, so that the foundation steel bar 100 can be inserted into the connection groove 11 to achieve connection, and the operation is more convenient. The extension member 2 is connected to the sleeve member 1 and is coaxially arranged with the sleeve member 1, ensuring the stability of the connection and avoiding stress concentration caused by misalignment. The extension member 2 is pre-embedded in the pile body 200 and is extended along the first direction. The extension member 2 is connected to the main reinforcement 201 of the pile body 200 through the extension member 2, so that the pile body 200 and the foundation steel bar 100 are tightly connected. By prefabricating the connection member, the connection operation between the pile body 200 and the foundation can be simplified, the operation is convenient, the efficiency is higher, and there is no need to break the pile, and the operation is safer. Through the above-mentioned arrangement, the connection member of this embodiment can efficiently and conveniently achieve a stable connection between the pile body 200 and the foundation, and the safety is higher.

[0031] It should be noted that in this embodiment, the sleeve member 1 and the extension member 2 can be made of steel bars to facilitate local materials and on-site processing. In other embodiments, the above components can also be made of steel bars, as long as they can achieve the above functions, and no further restrictions are made here.

[0032] Specifically, Figure 1-Figure 3 As shown, along the first direction, the connecting groove 11 and the extension piece 2 are coaxially arranged, ensuring the alignment of the connecting groove 11 and the extension piece 2 on the central axis, avoiding misalignment and deviation, making the connection between the foundation steel bar 100 and the main reinforcement 201 of the pile body more accurate and firm, and reducing stress concentration and potential damage risks.

[0033] More specifically, if Figure 2 and Figure 3 As shown, the sleeve member 1 is extended from the pile body 200 , so that it is convenient for operators to connect the sleeve member 1 with the foundation steel bar 100 , thereby ensuring a stable connection between the pile body 200 and the foundation.

[0034] Specifically, a thread is processed at the end of the base steel bar 100 so that the end of the base steel bar 100 can extend into the connecting groove 11 and cooperate with the thread of the sleeve member 1. Through the mutual engagement of the threads, the friction and tensile strength at the connection between the base steel bar 100 and the sleeve member 1 are increased, thereby improving stability and reliability.

[0035] Specifically, an extension groove is provided on the extension member 2, and the extension groove is extended along the first direction to ensure that the extension groove can be smoothly connected to the pile body main reinforcement 201. By processing a thread on the end of the pile body main reinforcement 201, the end of the pile body main reinforcement 201 can extend into the extension groove and cooperate with the thread of the extension member 2, thereby improving the connection strength and stability between the pile body main reinforcement 201 and the extension member 2, which helps to achieve a stable connection between the pile body 200 and the foundation.

[0036] More specifically, the connector also includes a separator, which is disposed between the connecting groove 11 and the extension groove to ensure that the connecting groove 11 and the extension groove do not interfere with each other during connection, thereby improving the accuracy and stability of the connection. The separator can be implemented by steel bars or bolts, which is not limited here.

[0037] Specifically, Figure 1-Figure 3 As shown, a cylinder 202 is provided on the main reinforcement 201 of the pile body, and the extension piece 2 can extend into and be connected to the cylinder 202, thereby ensuring a tight connection between the main reinforcement 201 of the pile body and the connecting piece. Moreover, since the cylinder 202 is generally provided together with the prefabricated pile body 200, construction time is saved. Such a configuration facilitates the mutual connection between the extension piece 2 and the cylinder 202, and the operation is more convenient.

[0038] More specifically, the extension piece 2 is provided with an external thread, and the barrel 202 is provided with an internal thread that matches the external thread. The connection is achieved by the mutual engagement of the external thread and the internal thread, thereby ensuring the connection stability between the barrel 202 and the extension piece 2.

[0039] Specifically, Figure 1-Figure 3 As shown, the diameter of the sleeve member 1 is larger than that of the extension member 2. Since the sleeve member 1 needs to be connected to an external structure such as the foundation reinforcement 100, its diameter is larger so as to better cooperate with the reinforcement of standard specifications; and the extension member 2, as a transition part between the main reinforcement 201 of the pile body and the sleeve member 1, has a smaller diameter and can be more easily extended into the cylinder 202 of the main reinforcement 201 of the pile body and cooperate with the thread inside the cylinder 202.

[0040] Specifically, in this embodiment, the material of the connecting piece is steel, which has high tensile, compressive and shear strengths, and is convenient for local materials to improve construction efficiency. In other embodiments, the connecting piece may also be made of alloy steel or carbon steel, which is not limited here.

[0041] It should be noted that, in this embodiment, the foundation steel bar 100 and the main reinforcement 201 of the pile body are arranged coaxially, which can meet the design requirements and increase the pull-out bearing capacity. In addition, the cost of pile breaking construction and welding construction is relatively high, and the pile breaking construction requires first breaking the pile body concrete, and then leaking the prestressed steel rod for welding operations. In this embodiment, the operator can achieve a stable connection between the foundation steel bar 100 and the main reinforcement 201 of the pile body through the connecting piece, which has a low construction cost, increases the construction speed, shortens the construction period, and has low requirements for manual skills and more stable structural quality.

[0042] 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.
