Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A device for preventing deviation of building pile foundations comprises two symmetrically arranged L-shaped support frames 1, wherein a mounting slot 2 is provided on the side close to each other of the two L-shaped support frames 1, two mounting holes 3 are provided on the top of the L-shaped support frames 1, and a U-shaped positioning rod 4 is provided on the L-shaped support frames 1.

[0026] An arc-shaped positioning card 5 is provided on one side of the L-shaped support frame 1, and a rectangular mounting block 6 is fixedly connected to one side of the arc-shaped positioning card 5 and located inside the mounting slot 2. Two through holes 7 are provided on the rectangular mounting block 6, and the two through holes 7 and the two mounting holes 3 are respectively aligned in the same vertical direction. The U-shaped positioning rod 4 passes through the mounting holes 3 and the through holes 7 in sequence and extends to the inside of the L-shaped support frame 1. A control connecting plate 8 is fixedly connected to one side of the U-shaped positioning rod 4, and the control connecting plate 8 is attached to one side of the L-shaped support frame 1.

[0027] like Figure 2 and Figure 3 The U-shaped positioning rod 4 is inverted so that its bent portion is located above the L-shaped support frame 1. When the rectangular mounting block 6 is inserted into the mounting slot 2, the through hole 7 and the mounting hole 3 are aligned together in the vertical direction. The U-shaped positioning rod 4 passes through the through hole 7 and the mounting hole 3 to position the rectangular mounting block 6 in the L-shaped support frame 1, so that the arc-shaped positioning card 5 cannot be separated from the L-shaped support frame 1.

[0028] A plurality of positioning side plates 9 are fixedly connected to one side of the L-shaped support frame 1 , and the plurality of positioning side plates 9 are symmetrically arranged on both sides of the control connecting plate 8 .

[0029] like Figure 2, a plurality of positioning side plates 9 are respectively attached to both sides of the control connecting plate 8, playing a role in positioning the control connecting plate 8.

[0030] One side of the control connecting plate 8 is fixedly connected with a rectangular sleeve 10. One side of the inner wall of the rectangular sleeve 10 is fixedly connected with a spring 11. One end of the spring 11 is fixedly connected with a clamping block 12. A clamping groove 13 for cooperating with the clamping block 12 is formed on one side of the L-shaped support frame 1.

[0031] Such as Figure 2 and Figure 5 , when the clamping block 12 is inserted into the clamping groove 13, it can prevent the control connecting plate 8 from moving up and down on one side of the L-shaped support frame 1.

[0032] One end of the clamping block 12 is fixedly connected with a connecting rod 14. The top of the connecting rod 14 and above the rectangular sleeve 10 is fixedly connected with a control handle 15.

[0033] Such as Figure 2 and Figure 5 , the connecting rod 14 is in a "C" shape, and one end of it passes through the inside of the rectangular sleeve 10.

[0034] Both sides of the L-shaped support frame 1 are fixedly connected with transverse plates 16. A locking screw rod 17 is arranged between the two transverse plates 16. Two locking nuts 18 are threadedly connected to the locking screw rod 17.

[0035] Such as Figure 1 , both ends of the locking screw rod 17 pass through the transverse plates 16 on the two L-shaped support frames 1, and the locking nuts 18 are located on the sides of the two transverse plates 16 away from each other.

[0036] An anchoring rod 19 is threadedly connected to the L-shaped support frame 1. An annular sleeve 20 is fixedly connected to the L-shaped support frame 1. A locking cover 21 is threadedly connected to the annular sleeve 20.

[0037] Such as Figure 2 , the L-shaped support frame 1 can be anchored through the anchoring rod 19. The locking cover 21 can be threadedly connected to the annular sleeve 20 to lock the top of the anchoring rod 19 from above, preventing the anchoring rod 19 from loosening, and at the same time, it can also provide waterproof protection for the top of the anchoring rod 19.

[0038] The working principle of a building pile foundation anti-deviation device provided by the present utility model is as follows:

[0039] When it is necessary to prevent the building pile foundation from deflecting, the two L-shaped support frames 1 are set on both sides of the building pile foundation. At this time, the locking nut 18 is rotated, the locking nut 18 squeezes the transverse plate 16, and the transverse plate 16 squeezes the L-shaped support frame 1, so that the arc-shaped positioning clamps 5 of the two L-shaped support frames 1 are attached to the building pile foundation, and the building pile foundation is positioned to prevent the building pile foundation from deflecting, and then the L-shaped support frame 1 is fixed by the anchor rod 19;

[0040] When the control handle 15 is manually pulled away from the control connecting plate 8, the clamping block 12 and the clamping groove 13 can be separated through the connecting rod 14. At this time, the control handle 15 can be pulled upward to drive the rectangular sleeve 10 and the control connecting plate 8 to move upward. The upward movement of the control connecting plate 8 drives the U-shaped positioning rod 4 to move upward, so that the U-shaped positioning rod 4 and the through hole 7 are separated. At this time, the arc positioning clamp 5 can be pulled away from the L-shaped support frame 1, so that the rectangular mounting block 6 is disengaged from the mounting slot 2, and the arc positioning clamp 5 is removed;

[0041] On the contrary, when replacing arc-shaped positioning cards 5 of different specifications, the rectangular mounting block 6 can be inserted into the mounting slot 2, and then the control connecting plate 8 can be moved downward. The control connecting plate 8 drives the U-shaped positioning rod 4 to move downward, and the U-shaped positioning rod 4 passes through the through hole 7 to position the rectangular mounting block 6 and the arc-shaped positioning card 5, and the installation of the rectangular mounting block 6 and the arc-shaped positioning card 5 is completed. Then the spring 11 pushes the clamping block 12 into the clamping slot 13 to position the control connecting plate 8 to prevent the U-shaped positioning rod 4 from moving up and down and causing the rectangular mounting block 6 and the arc-shaped positioning card 5 to loosen.

[0042] Compared with the related art, the anti-deviation device for building pile foundation provided by the utility model has the following beneficial effects:

[0043] The present invention can realize the positioning of the building pile foundation by clamping the arc-shaped positioning clamps 5 on both sides to the two sides of the building pile foundation, avoiding the deflection of the building pile foundation, and at the same time, by pulling the U-shaped positioning rod 4 upwards, the arc-shaped positioning clamps 5 can be quickly installed and disassembled, which is convenient for preventing the deflection of building pile foundations with different radii. Arc-shaped positioning clamps 5 of different specifications can be replaced to position the building pile foundation, thereby achieving a better positioning effect on the building pile foundation.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
