[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without making creative efforts all fall within the protection scope of the present utility model.

[0023] The specific embodiments of the present utility model will be described below in conjunction with the accompanying drawings. Specific Embodiment 1:

[0025] Referring to Figures 1-5 , a positioning device for prefabricated box girder steel reinforcement cages, comprising a frame body 1. A cross bar 3 and a vertical bar 4 are arranged inside the chassis of the frame body 1, and the cross bar 3 and the vertical bar 4 are arranged in a staggered manner to form a chassis frame. A telescopic column 2 is arranged at the bottom surface of the vertical bar 4. Rectangular mounting bars 8 inclined outward are arranged on both sides of the cross bar 3. An L-shaped support column 10 is arranged at the end of the rectangular mounting bar 8 far away from the cross bar 3. Among them, the cross bar 3 and the vertical bar 4 are angle steels, and the cross bar 3 and the vertical bar 4 are mutually staggered to form the chassis structure of the frame body 1. The rectangular mounting bar 8 is a channel steel, which has relatively high bending resistance and load-bearing capacity. Both the telescopic column 2 and the L-shaped support column 10 have telescopic functions to control the position of the frame body 1 and adjust the arrangement modes for different prefabricated box girder steel reinforcement cages. Transverse limiting grooves 5 are arranged on the side wall of the cross bar 3 along its length direction, and vertical limiting grooves 6 are arranged on the side wall of the vertical bar 4 along its length direction. The transverse limiting grooves 5 and the vertical limiting grooves 6 are both for facilitating the fixing of steel bars. When the user measures, the problem of the accuracy of the spacing of the steel reinforcement cage will not be caused due to the displacement of the steel bars. These limiting groove bodies are designed according to unit modules and can also play a role in assisting measurement.

[0026] As mentioned before, the bottom surface of the steel cage is made using the cross bar 3 and the vertical bar 4. Along the length direction of the side wall of the rectangular mounting bar 8, position adjusters 11 are arranged. And on the side wall of the rectangular mounting bar 8 near one end of the cross bar 3, a limiting bar 7 is provided. Along the length direction of the side wall of the limiting bar 7, inclined limiting grooves 9 are arranged. And the limiting bar 7 and the rectangular mounting bar 8 are welded to each other. The side steel cages are spaced by the limiting bar 7. The limiting bar 7 is also an angle steel. Similar to the cross bar 3 and the vertical bar 4, there are also inclined limiting grooves 9 on the side wall of the limiting bar 7. Its function is also to fix the steel bars. Generally, the steel cages on the side of the box girder have an angle, so steel bars are no longer used as auxiliary positioning devices. The protruding end face of the position adjuster 11 has an auxiliary hole 12 passing through it. And on the groove surface of the position adjuster 11 that fits the rectangular mounting bar 8, a fixing button 13 is provided. Here, it is replaced with the position adjuster 11. There are grooves on the protruding surface of the position adjuster 11 to place the steel bars. The position adjuster 11 is used to control the lateral spacing of the inclined surface. There is a fixing button 13 on the position adjuster 11. In order to fix the positioning of the position adjuster 11 on the rectangular mounting bar 8, the user can measure the spacing between the steel bars with a ruler. The auxiliary hole 12 on the protruding surface of the position adjuster 11 facilitates precise assistance during measurement. At the same time, it can also be fixed by passing a steel wire through the hole. Using the limiting bar 7 as a reference and the position adjuster 11 as an auxiliary measurement, the best editing position of the precast steel cage for the inclined surface of the box girder is selected. The telescopic column 2 and the vertical bar 4 are connected by bolts. And the telescopic column 2 is installed through the staggered positions of the cross bar 3 and the vertical bar 4. The L-shaped support column 10 controls the angle of the rectangular mounting bar 8 through folding and telescoping. The rectangular mounting bar 8 and the cross bar 3 are hinged. By the telescopic properties of the telescopic column 2 and the L-shaped support column 10, the precast steel cage of the box girder is held against the box girder to further check whether the steel cage fits the box girder. After confirmation, the steel cage can be withdrawn. At this time, the fixing button 13 can be pressed to turn the position adjuster 11 to protect the protruding surface to prevent the position adjuster 11 from being hit when the steel cage is withdrawn. Of course, the angle of the inclined surface frame can also be adjusted by the L-shaped support column 10 and the rectangular mounting bar 8 to assist in withdrawing. Specific Embodiment Two:

[0028] Based on the above embodiment, cross bars 3 and vertical bars 4 are provided inside the chassis of the frame main body 1. And the cross bars 3 and the vertical bars 4 are arranged in a staggered manner to form a chassis frame. Of course, in this embodiment, the cross bars 3 and the vertical bars 4 are not fixedly designed. Especially the horizontal limiting grooves 5 on the cross bar 3 and the vertical limiting grooves 6 on the vertical bar 4 can also be designed differently to have a clearer positioning of the editing accuracy of the steel cage and the required target spacing.

[0029] To sum up:

[0030] 1. An active fixing bracket is adopted. Through the horizontal limiting groove 5 on the cross bar 3 and the vertical limiting groove 6 on the vertical bar 4, the accurate positioning of the chassis of the steel reinforcement cage and the control of the spacing are easier to identify. Through the upper limiting bar 7 of the rectangular mounting bar 8 and the position adjuster 11, the steel reinforcement cage on the side is accurately positioned. The active adjustment of the L-shaped support column 10 and the telescopic column 2 adjusts the positioning angle for different box girder sizes, realizing the flexible adjustment of the spacing of the steel reinforcement cage, solving the problem that the staff generally uses a manual ruler to measure and draw lines and then binds the steel bars at the drawn line positions. However, when using manual drawing for positioning, it is easy to cause inaccurate positioning of the steel bars. The stability of the steel reinforcement cage ensures the safety of the measurer.
