Description

Technical Field

[0001] The utility model relates to the field of pier column prefabrication, in particular to a prefabricated pier column cap positioning tool. Background Art

[0002] When building bridges or other facilities, a cap is set up under the column. During prefabrication, steel bars need to be reserved at the top of the cap, and holes need to be reserved at the bottom of the column to facilitate the connection between the two. Therefore, the accuracy requirements for both are relatively high. When pouring existing caps, workers generally use prefabricated steel cages to position the steel bars, tie the positioning steel bars together, and then pour. This method may have deviations in positioning accuracy, resulting in misalignment when connecting the cap and the column. Second, tying is time-consuming and not conducive to improving efficiency. Summary of the invention

[0003] In order to solve the above problems, the technical solution of the utility model is: a prefabricated pier column cap positioning tool, which consists of a U-shaped base plate, and the base plate is conveniently and evenly provided with through holes along the four sides. Positioning devices are installed at the through holes. The positioning device includes a positioning tube and a nut fixedly installed on the outer wall of the positioning tube. A bolt matching the nut is installed on the nut, and the other end of the bolt extends into the positioning tube.

[0004] In order to facilitate the removal of the positioning fixture, the bolts on the positioning tube are all facing downward.

[0005] In order to strengthen the bottom plate, transverse ribs and vertical ribs are installed around the bottom plate, and the ends of the transverse ribs and vertical ribs are fixedly connected to each other.

[0006] In order to facilitate the lifting and placement of the positioning tool, lifting ears are fixedly installed at both ends of the vertical reinforcement.

[0007] In order to facilitate tightening and loosening of the bolts, the vertical ribs and the lower transverse ribs are both located on the inner side of the positioning device, and the upper transverse ribs are fixed on the side away from the bolts.

[0008] In order to strengthen the connection strength between the nut and the positioning tube, the nut is fixedly welded to the outer wall of the positioning tube through a connecting plate.

[0009] The beneficial effects of the utility model are:

[0010] The device can pass the steel bar through the positioning tube, and then lock it with bolts to position the steel bar. The positioning device has accurate positioning and requires a short time, which is conducive to improving efficiency.

[0011] The device can be recycled, which greatly saves materials and prefabrication time. At the same time, the device has a simple structure, low cost, and is easy to maintain and promote. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] exist Figure 1 and Figure 2 A prefabricated pier cap positioning tool is provided, which comprises a U-shaped base plate 1, wherein the base plate 1 is evenly and conveniently provided with through holes along four sides, and positioning devices 2 are installed at the through holes. The positioning device 2 comprises a positioning tube 21 and a nut 23 fixedly installed on the outer wall of the positioning tube 21, and a bolt 24 matching with the nut 23 is installed on the nut 23, and the other end of the bolt 24 extends into the positioning tube 21.

[0017] Furthermore, the bolts 24 on the positioning tube 21 are all facing downward.

[0018] Furthermore, transverse ribs 4 and vertical ribs 3 are installed around the base plate 1 , and ends of the transverse ribs 4 and vertical ribs 3 are fixedly connected to each other.

[0019] Furthermore, lifting ears 5 are fixedly installed at both ends of the vertical rib 3 .

[0020] Furthermore, the vertical ribs 3 and the lower transverse ribs 4 are both located on the inner side of the positioning device 2 , and the upper transverse ribs 4 are fixed on the side away from the bolts 24 .

[0021] Furthermore, the nut 23 is fixedly welded to the outer wall of the positioning tube 21 through the connecting plate 22 .

[0022] When in use, the positioning device is lifted to a predetermined position by a lifting device, the steel bar is inserted into the positioning tube 21, the steel bar inserted into the positioning tube 21 is locked by bolts 24, and then mud is injected through the gap in the middle of the positioning plate 1. After the injection is completed, the bolts 24 are loosened, and the positioning tooling is lifted by the lifting device and sent to the next workstation to continue the operation.

[0023] Since the bolts 24 are all facing downward, they can also be uniformly directed to other directions as needed, so that when the bolts 24 are loosened, it can be ensured that the tooling is separated from the steel bar more quickly.

[0024] Two transverse ribs 4 and two vertical ribs 3 are installed on the bottom plate 1, which can effectively strengthen the bottom plate 1, prevent it from being deformed during lifting, and extend its service life.

[0025] The installation positions of the transverse reinforcement 4 and the vertical reinforcement 3 do not affect the tightness of the bolt 23 , nor do they affect the tightening efficiency of the bolt 23 .
