Technical Field

[0001] The utility model is designed in the technical field of bridge engineering construction, and specifically relates to a positioning device for a column-row bridge pier reinforcement cage. Background Art

[0002] With the rapid development of the transportation industry, bridge projects are becoming more and more common. As the intermediate structure of the bridge, the construction quality of the pier directly affects the use of the bridge. During the construction of the pier, whether the pier steel cage is accurately positioned directly affects the quality of the pier. If the pier steel cage is offset, it will change the internal force distribution of the pier structure, affect the stability of the overall structure of the pier, and create uncontrollable risks. Therefore, before the pier is cast to form strength, it is necessary to ensure that the pier steel cage does not deviate.

[0003] The positioning device currently used for the steel cage of column-type bridge piers is a highway bridge column-type pier body steel cage positioning device proposed in the patent application with application number 202220561114.3, which includes a positioning hoop, the diameter of which is the same as the diameter of the reinforcing hoop of the pier column steel cage, the top surface of which is horizontal and welded to the upper part of the pile foundation steel bar, the center point of which coincides with the center point of the pier, and the positioning hoop is also fixed by a triangular brace. Although this patent solves the problem of pier steel cage positioning, it has the following shortcomings:

[0004] 1. Only a single steel cage can be positioned, but the relative positions of the steel cages of the two piers cannot be positioned.

[0005] 2. The same positioning device can only be used to fix one type of steel cage, and its versatility is poor. Utility Model Content

[0008] Preferably, the positioning assembly includes a positioning top plate and a corresponding positioning bottom plate, and a steel bar positioning tube with a hollow interior is connected between the positioning top plate and the positioning bottom plate; a positioning hole having the same inner diameter as that of the steel bar positioning tube is formed on the positioning top plate.

[0009] Preferably, the inner diameter of the steel bar positioning tube is equal to the diameter of the steel bars of the steel cage.

[0010] Preferably, a plurality of groups of positioning bolt holes are arranged on the slide rail plate.

[0012] Preferably, the positioning base plate can also be rotatably connected to a pulley, and the slide rail plate is also provided with a guide rail groove; the pulley can roll along the guide rail groove.

[0013] Preferably, there is a frame diagonal connecting rod between the top frame and the bottom frame to stabilize the support frame.

[0014] Preferably, a hook groove for lifting is provided on the outer side of the bottom frame.

[0015] Compared with the prior art, the above technical solution has the following advantages or beneficial effects:
