[0026] Combine the following Figure 1-Figure 4 The utility model describes a pier body steel bar positioning device.

[0027] The present embodiment provides a pier body steel bar positioning device, comprising a plurality of positioning fixtures 1, wherein the plurality of positioning fixtures 1 are arranged at intervals along the height direction, and two adjacent positioning fixtures 1 are connected by a retractable column 2. Each of the positioning fixtures 1 is of the same size and is adapted to the outer contour of the pier body. The inner side of each positioning fixture 1 is evenly provided with a plurality of positioning sockets for clamping the embedded steel bars.

[0028] When the utility model is used in a construction site, it can be set on a foundation, and the embedded steel bars can be positioned at different heights by using a plurality of positioning fixtures 1, and the embedded steel bars can be fixed in the positioning fixtures, which can not only ensure that the spacing between adjacent embedded steel bars in the height direction is stable and meets the installation standards, but also reduce the installation time of the embedded steel bars, reduce the labor intensity of workers, improve the installation quality of the embedded steel bars of the pier body, and further improve the construction quality of the pier body casting; in addition, two adjacent positioning fixtures 1 are connected by a retractable column 2, and the spacing between the positioning fixtures 1 can be adjusted to adapt to embedded steel bars of different lengths, thereby further improving the positioning quality of the embedded steel bars.

[0029] In some embodiments, the distance between two adjacent positioning slots is 150-200 mm, and the width of the positioning slots is 20-30 mm.

[0030] In this embodiment, two positioning fixtures 1 are included to form a double-layer adjustable pier body steel bar positioning device. The two positioning fixtures 1 are connected by a retractable column 2. The inner side of each positioning fixture 1 is evenly distributed with a plurality of positioning clips for clamping the embedded steel bars. The spacing between two adjacent positioning clips is 150 mm, and the width of the positioning clips is 25 mm.

[0031] In this embodiment, the positioning fixture 1 is made according to the outer contour shape of the pier body. The positioning fixture 1 includes a straight segment template 11, a first arc template 12 and a second arc template 13. A pair of straight segment templates 11 are provided. The two ends of the first arc template 12 are respectively connected to the first ends of the pair of straight segment templates 11, and the two ends of the second arc template 13 are respectively connected to the second ends of the pair of straight segment templates 11.

[0032] like Figure 1 As shown, the positioning fixture 1 is waist-shaped, the first arc template 12 and the second arc template 13 are both semicircular structures, and a pair of straight segment templates 11, the first arc template 12 and the second arc template 13 are sequentially connected to form a closed frame structure.

[0033] Preferably, the straight segment template 11 is detachably connected to the first arc template 12 and the second arc template 13.

[0034] Therefore, the pier body steel bar positioning device has the advantages of easy installation, convenient transportation, and stable structure.

[0035] In some embodiments, a first connecting hole is provided at the end of the straight line segment template 11, and a second connecting hole is provided at the ends of the first arc template 12 and the second arc template 13. The straight line segment template 11 is connected to the first arc template 12 and the second arc template 13 by bolts passing through the first connecting hole and the second connecting hole in sequence.

[0036] With such arrangement, the reliability and stability of the overall structure can be ensured through the connection structure, and at the same time, the assembly efficiency of the entire positioning device is improved, which is convenient for the actual operation of the operator.

[0037] Furthermore, a concave-convex positioning structure is provided at the connection between the straight segment template 11 and the first arc-shaped template 12 and the second arc-shaped template 13 .

[0038] Such arrangement improves the connection stability and positioning accuracy between two adjacent templates through the concave-convex positioning structure, thereby ensuring the stability and reliability of the overall structure.

[0039] In some embodiments, the concave-convex positioning structure includes a protrusion and a groove, the protrusion is arranged at the end of the straight segment template 11, and the first connecting hole passes through the protrusion; the groove is arranged at the end of the first arc template 12 and the second arc template 13, the groove is adapted to the protrusion, and the second connecting hole passes through the side wall of the groove; for example, Figure 3 As shown, a protrusion is set in the middle of the end connecting surface of the straight segment template 11, and a groove is opened in the middle of the end connecting surface of the first arc template 12 and the second arc template 13. Accurate positioning is quickly achieved through the concave and convex fit, and then the two adjacent templates are connected by bolts.

[0040] In other embodiments, Figure 4 As shown, the concave and convex positioning structures can also be stepped structures that cooperate with each other.

[0041] Reference Figure 2 In this embodiment, the telescopic column 2 includes a sleeve 21 and a connecting rod 22. The connecting rod 22 is axially movably arranged in the sleeve 21. The connecting rod 22 is axially provided with a plurality of adjustment holes. The sleeve 21 is provided with a positioning hole. The sleeve 21 is connected to the connecting rod 22 by passing a connecting pin through the positioning hole and the adjusting hole.

[0042] With such arrangement, when the height of the telescopic column 2 needs to be adjusted, the connecting rod 22 or the sleeve 21 is moved axially, for example, the connecting rod 22 is pulled out of the sleeve 21 to increase the overall length of the telescopic column 2, or the connecting rod 22 is further pushed into the sleeve 21 to shorten the overall length of the telescopic column 2, thereby adjusting the height spacing between two adjacent positioning fixtures 1 to meet the installation requirements of embedded steel bars of different lengths.

[0043] Furthermore, scale lines are axially arranged on the outer sides of the sleeve 21 and the connecting rod 22 to improve precision and accuracy, so that the telescopic column 2 can have more precise length markings when telescoping, which is convenient for the user to accurately adjust to the required length. The user can easily record or monitor the length change of the telescopic rod, thereby improving work efficiency and safety.
