Description

Technical Field

[0001] This utility model relates to the field of building foundation engineering technology, and in particular to a snap-fit ​​reinforced weldless pipe pile and its connecting device. Background Technology

[0002] PHC pipe piles are commonly used in construction. During construction, when the length of the pipe piles is insufficient, splicing is required to connect the two piles. Current splicing methods involve adding iron plates at the joint surface and welding them together. However, due to the complex construction environment, common problems include cross-sectional connection errors in the pipe piles and difficulty in guaranteeing welding quality. When driving the piles to the work position, limited working conditions and poor lighting can easily lead to welding quality problems such as incomplete welds, false welds, missed welds, and slag inclusions, resulting in unstable strength of the welded structure. Solving these problems is a research direction. Therefore, it is necessary to propose a non-welding method that can conveniently connect PHC pipe piles. Summary of the Invention

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0022] In one technical solution of this utility model, Figure 1 This is a structural diagram illustrating the specific structure of a snap-fit ​​reinforced weldless pipe pile connection device according to this technical solution, as shown below. Figure 1 As shown, this utility model includes: a first embedding component 1 and a second embedding component 2.

[0023] like Figure 2 As shown, the first fixing component 1 includes a first fixing ring 11, and a plurality of slot posts 12 are provided at intervals at the bottom of the first fixing ring 11. Each slot post 12 has a slot 13 on one side, and a first connecting groove 14 is provided on the inner wall of the first fixing ring 11.

[0024] like Figure 3 As shown, the second fixing component 2 includes a second fixing ring 21. The top of the second fixing ring 21 is provided with a plurality of snap-fit ​​posts 22 at intervals. Each snap-fit ​​post 22 has a mounting groove 23 on one side. Each mounting groove 23 is provided with a spring 24. The end of the spring 24 facing away from the mounting groove 23 is connected to a locking block 25. The inner wall of the second fixing ring 21 is provided with a second connecting groove 26.

[0025] The first connecting groove 14 and the second connecting groove 26 are both connected to the pipe pile body. The upper and lower ends of a pipe pile body are respectively connected to the first embedding component 1 and the second embedding component 2, so that the two pipe pile bodies can be connected in a matching manner.

[0026] When the first embedding component 1 and the second embedding component 2 are connected, the card block 25 is placed in the card slot 13.

[0027] In one embodiment of this technical solution, such as Figure 4 As shown, a retaining groove 15 is also provided on the inner wall of the first fixing ring 11. The retaining groove 15 is located below the first connecting groove 14. A portion of the snap-fit ​​post 22 is provided with an upwardly inclined threaded hole 27, which is oriented upwards and aligned with the retaining groove 15. A threaded steel bar 3 is threadedly connected to the threaded hole 27, and the tail end of the threaded steel bar 3 is embedded in the retaining groove 15. The threaded steel bar is used to reinforce the first retaining component 1 and the second retaining component 2.

[0028] To facilitate better connection of the rebar, the embedding groove 15 can be provided with threads that are compatible with the rebar. The rebar 3 uses a steel grade of not less than HRB335, and its upper part has a cross-shaped opening. After the upper and lower pile sections are joined together, they are connected to the rebar embedding groove 15 through the threaded hole 27 of the second embedding component 2 and then tightened for fixation.

[0029] In one embodiment of this technical solution, the number of the rebar 3 is 2-4 pieces.

[0030] In one embodiment of this technical solution, the spacing between adjacent slot posts 12 is equal to or less than the width of the buckle post 22.

[0031] In one embodiment of this technical solution, such as Figure 5 As shown, the top surface of the slot 13 is inclined towards the first fixing ring 11, and the locking block 25 is adapted to the slot 13. After the first locking component 1 and the second locking component 2 are connected to the slot 13 through the locking block 25, they cannot be pulled out.

[0032] In another technical solution of this utility model, a snap-fit ​​reinforced weldless pipe pile is provided, including a pipe pile body 4 and a connection device for the snap-fit ​​reinforced weldless pipe pile described above.

[0033] like Figure 6 and Figure 7 As shown, the top and bottom ends of the pipe pile body 4 are respectively provided with a first fixing flange 41 and a second fixing flange 42, and the first fixing flange 41 and the second fixing flange 42 are respectively placed in the first connecting groove 14 and the second connecting groove 26.

[0034] The first retaining flange 41 and the second retaining flange 42, as well as the first connecting groove 14 and the second connecting groove 26, are all made of metal. When the pile body is formed, the first connecting groove 14 is fitted onto the first retaining flange 41, and the second connecting groove 26 is fitted onto the second retaining flange 42, so that the retaining component can rotate around the pile body. That is, the retaining flange is placed in the connecting groove when the pile body is formed.

[0035] This invention improves construction convenience, shortens single-node construction time, reduces equipment positioning accuracy requirements, avoids corrosion in the welding heat-affected zone, and extends the service life of the piles by connecting the first and second fixing components of two piles and fixing them with locking blocks and slots. This invention also provides radial constraint by reinforcing the first and second fixing components with steel bars, forming a double-redundant force-bearing system.

[0036] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it.
