[0028] Example

[0029] This embodiment provides a pile core positioning and verification tool for determining the position of the concrete cast-in-place pile core to facilitate later coring. Figure 1 As shown, the pile core verification tool is arranged at the top of the bored pile, and comprises a rotating connector 1, and a plurality of side bars 2 rotatably connected to the rotating connector 1 are arranged around the rotating connector 1, and the measuring bar 2 is a flexible member so as to move in the gap between the steel bars reserved at the top of the bored pile, and the measuring bar 2 is provided with a plurality of hanging holes 3 along its axial direction, and a hanging rod 4 detachably connected to the measuring bar 2 is arranged in one of the hanging holes 3, and this structure further facilitates the construction personnel to move the measuring bar 2, and they do not have to bend down all the time to adjust the measuring bar 2.

[0030] like Figure 2 to Figure 3 As shown, the length of the measuring bar 2 is greater than the radius of the cast-in-place pile, and a scale is provided on the measuring bar 2 along its axial direction. This structure facilitates rapid adjustment of the measuring bar.

[0031] In this embodiment, the hanging hole 3 is arranged on one side of the scale, and a reinforcement ring 5 is arranged in the hanging hole 3. Since the measuring strip 2 is a flexible part, the reinforcement ring 5 is added in the hanging hole 3 to reduce the damage caused to the hanging hole 3 by the hanging rod 4 during the construction process.

[0032] like Figure 4 As shown, one end of the hanging rod 4 is in a hook shape, through which it is detachably connected to the hanging hole 3, and the other end is provided with a handle. When in use, the construction worker holds the handle, and the hook end is connected to the hanging hole 3, which is convenient for adjusting the position of the measuring bar 2. The winning measuring bar 2 is quickly rotated from one adjacent reserved steel bar to another adjacent reserved steel bar, so as to determine or verify the pile core.

[0033] like Figure 5As shown, the bottom of the rotating connector 1 is provided with a positioning piece 6 which is detachably connected thereto. The positioning piece 6 includes a circular piece and a connecting piece. The connecting piece is arranged at the center of the top of the circular piece and is used to connect the circular piece to the rotating connector 1. The size of the circular piece is the same as the size of the pile core required by the drilling method. After determining the position of the pile core, the positioning piece 6 can be pressed by the hanging rod 4 and the rotating connector 1 can be moved upward by the measuring bar 2 so that the positioning piece 6 is temporarily left at the pile core, so as to facilitate the subsequent determination of the pile core position; the pile core position can also be determined by entering the top of the cast-in-place pile and spraying paint along the prototype.

[0034] The measuring strip 2 in the utility model is a flexible piece, and a plurality of measuring strips 2 are rotatably connected by a rotating connecting piece 1, which is convenient for checking the pile core and convenient for storage and carrying. By providing a hanging hole 3 on the measuring strip 2, the measuring strip 2 can be quickly moved and adjusted by a hanging rod 4 connected to the hanging hole 3, so as to quickly determine the position of the pile core, which is convenient and quick.

[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
