[0007] Further defined, in the above technical solution, an annular notch is further arranged on the side wall of the square pile body, and a protective cover is embedded in the annular notch; it can provide good protection for the connection bolts.

[0008] Further defined, in the above technical solution, the distance between the annular notch and the opening groove is 10 - 15 cm.

[0009] The beneficial effects of the present utility model are as follows: The bolt - connected prestressed hollow square pile proposed by the present utility model adopts bolt - fixed connection, featuring fast construction speed, high connection strength, ensuring the overall construction quality of the building, and improving the overall building safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings described below are only some embodiments recorded in the present application. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0011] Figure 1 is the structural schematic diagram of the present utility model;

[0012] Figure 2 is the structural schematic diagram of the end face of the square pile body in the present utility model.

[0013] The reference numerals in the drawings are: 1, square pile body; 2, circular through - hole; 3, connecting plate; 4, opening groove; 5, fixing hole; 6, connecting bolt; 7, annular notch; 8, protective cover. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model more clearly understood, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] In the present application, the connecting bolt 6 can be a single - headed threaded rod or a double - headed threaded rod. When using a double - headed threaded rod, its fixed connection is achieved by tightening the two nuts; when using a single - headed threaded rod, it is fixed by passing one end through the fixing hole 5 and then connecting a nut; at the same time, internal threads can also be provided in the fixing hole 5. In this way, when using a single - headed threaded rod, it only needs to be directly tightened on the connecting plate 3 to achieve fixed connection.

[0016] See Figure 1 and Figure 2Shown is a bolt-connected prestressed hollow square pile, including a square pile body 1. A circular through-hole 2 is provided in the middle of the square pile body 1. The outer wall cross-section of the square pile body 1 is of a square structure. Connecting components are respectively arranged at both ends of the square pile body 1. The connecting components include connecting plates 3, open slots 4, fixing holes 5 and connecting bolts 6. The connecting plates 3 are respectively vertically arranged at both ends of the square pile body 1. An open slot 4 is opened on one side of the connecting plate 3. The open slot 4 is arranged along the circumferential direction of the circular through-hole 2. Fixing holes 5 are opened on the connecting plates 3, and connecting bolts 6 are inserted into the fixing holes 5 for fixed connection.

[0017] Among them, the end area of the connecting plate 3 is the same as the end area of the square pile body 1. The opening spacing of the open slot 4 is 5 - 10 cm. A ring-shaped notch 7 is also provided on the side wall of the square pile body 1, and a protective cover 8 is embedded in the ring-shaped notch 7. The distance between the ring-shaped notch 7 and the open slot 4 is 10 - 15 cm.

[0018] The construction principle of the bolt-connected prestressed hollow square pile is as follows:

[0019] First, bring the end faces of the square pile bodies 1 closer to each other. When the connecting plates 3 are fitted together and the fixing holes 5 on the connecting plates 3 are ensured to be in concentric positions, insert and connect through the connecting bolts 6. After insertion, the end of the connecting bolt 6 is fixedly connected through a nut or the connecting bolt 6 is directly thread-connected with the internal thread provided on the fixing hole 5, so that the fixed connection between the square pile bodies 1 can be realized. Finally, install and fix by embedding the protective cover 8 in the ring-shaped notch 7, which can ensure the effective protection of the overall connection part.

[0020] The above-mentioned is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
