Generally, there are pre-buried protruding steel bars on the cap completed in the previous construction, and corresponding reserved holes are provided on the precast piers. During construction hoisting, each hole of the precast pier needs to be aligned with the pre-buried steel bars on the cap completed in the previous construction one by one and passed through the pre-buried steel bars to complete the assembly. Therefore, the installation accuracy requirements for the pre-buried steel bars on the cap are relatively high. However, the existing pre-buried steel bars on the cap are positioned by manual scribing, so there are problems of poor accuracy and low efficiency. Utility Model Content

[0024] As Figures 1 to 3 shown, the steel bar positioning device for precast pier cap provided by the embodiment of the present utility model includes a steel bar positioning frame 1 and a positioning rod 3.

[0025] The steel bar positioning frame 1 is a rectangular frame structure. A plurality of positioning grooves 2 are arranged on the inner side wall of the steel bar positioning frame 1. The positioning grooves 2 are arc-shaped grooves, and the upper and lower ends of the positioning grooves 2 penetrate through the steel bar positioning frame 1. The plurality of positioning grooves 2 are adapted to the embedded steel bars of the bearing platform.

[0026] On the outer sides of the four sides of the steel bar positioning frame 1, a positioning rod 3 is correspondingly arranged. The positioning rod 3 includes a screw rod 4, a sleeve 5 and a clamping block 6.

[0027] One end of the screw rod 4 is threadedly connected to one end inside the sleeve 5. The other end of the sleeve 5 is fixedly connected to the outer side wall of the steel bar positioning frame 1. The other end of the screw rod 4 is rotatably connected to the clamping block 6. A fixing groove 7 is arranged on the clamping block 6. The fixing groove 7 is a rectangular groove, and the fixing groove 7 and the structure of the bearing platform formwork 8 are adapted.

[0028] It should be noted that after the steel bars in the bearing platform formwork 8 are lapped, rotate the screw rod 4 to change the length of the positioning rod 3. Clamp the clamping block 6 to the upper edge of the bearing platform formwork 8 through its fixing groove 7, so that the device is fixed on the bearing platform formwork 8. Rotate the screw rod 4 to change the position of the steel bar positioning frame 1, so that the steel bar positioning frame 1 is adapted to the installation position of the precast bridge pier. After the adjustment is completed, relatively fix the screw rod 4 and the sleeve 5. The screw rod 4 and the sleeve 5 can be fixed by a locking nut. The locking nut passes through the threaded hole on the side wall of the sleeve 5 and abuts against the screw rod 4 to realize the relative fixation of the screw rod 4 and the sleeve 5. Then install the embedded steel bars through the positioning grooves 2. The positioning grooves 2 play a positioning role, thereby improving the installation accuracy of the embedded steel bars. For the same bridge pier, only the length of the positioning rod 3 needs to be adjusted once, so as to meet the rapid positioning requirements of multiple bridge piers, and further improve the installation efficiency of the embedded steel bars. After the embedded steel bars are installed, lift the device to disassemble the device. The device has a simple structure and strong practicability.

[0029] In this embodiment, the steel bar positioning frame 1 includes two long side positioning plates 9 and two short side positioning plates 10. The two long side positioning plates 9 are symmetrically arranged, the two short side positioning plates 10 are symmetrically arranged, and the long side positioning plates 9 and the short side positioning plates 10 are detachably connected. The positioning grooves 2 are arranged on the inner side wall of the long side positioning plates 9 or the short side positioning plates 10.

[0030] It should be noted that the structural setting of the steel bar positioning frame 1 facilitates its disassembly after the installation of the embedded steel bars, avoiding the problem that after the installation of the embedded steel bars, the embedded steel bars and the steel bar positioning frame 1 are tightly clamped and difficult to disassemble.

[0031] In this embodiment, a long side fixing hole 11 is arranged on the side of the long side positioning plate 9 connected to the short side positioning plate 10, and a short side fixing hole 12 is arranged on the side of the short side positioning plate 10 connected to the long side positioning plate 9. The short side positioning plate 10 overlaps on the long side positioning plate 9, and the bolt 13 passes through the long side fixing hole 11 and the short side fixing hole 12 and is connected to the nut.

[0032] It should be noted that the long-side positioning plate 9 and the short-side positioning plate 10 are fixed by bolts 13 and nuts, which is convenient for disassembly and firmly fixed.

[0033] In this embodiment, both the long-side fixing holes 11 and the short-side fixing holes 12 are elongated holes.

[0034] It should be noted that since both the long-side fixing holes 11 and the short-side fixing holes 12 are elongated holes, the connection positions of the long-side positioning plate 9 and the short-side positioning plate 10 can be adjusted, so as to form the steel bar positioning frames 1 with different widths and lengths to meet the usage requirements of different bearing platforms.

[0035] In this embodiment, the bolt 13 passes through the long-side fixing hole 11, the short-side fixing hole 12 and the lock washer and is then connected to the nut.

[0036] It should be noted that the lock washer can firmly fix the long-side positioning plate 9 and the short-side positioning plate 10.

[0037] In this embodiment, scales are provided on the edges of both the long-side fixing holes 11 and the short-side fixing holes 12.

[0038] It should be noted that when adjusting the connection positions of the long-side positioning plate 9 and the short-side positioning plate 10, the scales can quickly assist the staff to adjust them to the preset size.

[0039] In this embodiment, scales are provided on the screw rod 4.

[0040] It should be noted that when rotating the screw rod 4 to change the length of the positioning rod 3, the scales can quickly assist the staff to adjust it to the preset length.

[0041] In this embodiment, a threaded joint is provided on the outer side wall of the steel bar positioning frame 1, and the other end of the sleeve 5 is threadedly connected to the threaded joint.

[0042] It should be noted that the threaded joint facilitates the disassembly and assembly of the sleeve 5.

[0043] In this embodiment, for those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
