[0005] To achieve the above objectives, the present invention employs the following technical solution: An integral box culvert rebar positioning device includes a positioning column, a connecting plate, an outer positioning plate, and an inner positioning plate; the connecting plate is fixedly connected to the positioning column and located on one side of the positioning column; the outer positioning plate is detachably connected to the connecting plate as a whole and located on one side of the connecting plate; the inner positioning plate is detachably connected to the outer positioning plate and is disposed on one side of the connecting plate.

[0006] Based on the above-mentioned integral box culvert rebar positioning device, the connecting plate includes a base plate and a fixing bolt. The base plate is slidably connected to the fixing bolt and is located outside the fixing bolt. The fixing bolt is threadedly connected to the base plate and passes through the base plate.

[0007] Based on the above-mentioned integral box culvert rebar positioning device, the outer positioning plate includes a horizontal plate and a fixing head. The horizontal plate is fixedly connected to the base plate and is located on one side of the base plate. The fixing head is located on the top of the horizontal plate.

[0008] Based on the above-mentioned integral box culvert rebar positioning device, the inner positioning plate includes a clamping plate and a spring. The clamping plate is slidably connected to the base plate and is located near the side of the horizontal plate. The spring is fixedly connected to the clamping plate and the base plate respectively and is located between the base plate and the clamping plate.

[0009] Based on the above-mentioned integral box culvert reinforcement positioning device, the inner positioning plate also includes a telescopic rod, which is disposed inside the spring.

[0010] Based on the above-mentioned integral box culvert rebar positioning device, the fixing head includes a mounting base and a clamp. The mounting base has a groove located at the top of the mounting base. The clamp is slidably connected to the mounting base and is located on the side away from the horizontal plate.

[0011] The second objective of this invention is to provide an integral box culvert rebar binding frame.

[0012] To achieve the above objectives, the present invention employs the following technical solution: An integral box culvert rebar binding frame, employing an integral box culvert rebar positioning device, includes a base plate, columns, load-bearing beams, and reinforcing bars. The base plate is fixedly connected to the positioning column and located at the bottom of the positioning column. The column is threadedly connected to the base plate and located on the side close to the column. The load-bearing beam is fixedly connected to the column and located on the side away from the base plate. The reinforcing bars are fixedly connected to both the load-bearing beam and the column, and located between the load-bearing beam and the column.

[0013] The third objective of this invention is to provide a convenient method for binding the reinforcing steel bars of an integral box culvert.

[0014] To achieve the above objectives, the present invention employs the following technical solution: A method for positioning and binding reinforcing bars in an integral box culvert reinforcement binding frame includes the following steps: (1) Connect the positioning column (1) and the connecting plate to form a frame structure according to the size of the box culvert; (2) Connect the outer positioning plate and the inner positioning plate to the frame respectively; (3) Place the base plate (13) at the bottom of the frame, fix the column (14) on the base plate, and then fix the load-bearing beam on the top of the column to form an internal frame structure; (4) Place the reinforcing bars on the outside of the built-in frame and use the outer positioning plate and the inner positioning plate to clamp and fix the reinforcing bars. Finally, weld the reinforcing bar nodes to obtain the reinforcing bar skeleton. (5) Sequentially disassemble the outer positioning plate, the inner positioning plate, the connecting plate, and the positioning post; (6) Hoist the welded steel reinforcement cage upwards until the height exceeds the load-bearing and fixed structure of the steel reinforcement platform, then move it horizontally out to complete the positioning and binding of the steel reinforcement cage.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] Please see Figures 1 to 4 An integral box culvert rebar positioning device includes a positioning column 1, a connecting plate, an outer positioning plate, and an inner positioning plate; the connecting plate is fixedly connected to the positioning column 1 and located on one side of the positioning column 1; the outer positioning plate is detachably connected to the connecting plate as a whole and located on one side of the connecting plate; the inner positioning plate is detachably connected to the outer positioning plate and is disposed on one side of the connecting plate.

[0027] In this implementation scheme, the positioning column 1 is used to initially position the box culvert, thereby determining the volume of the box culvert and providing installation conditions for the connecting plate. The connecting plate provides installation conditions for the outer positioning plate and the inner positioning plate respectively. When the steel reinforcement cage is tied, the workers use the outer positioning plate and the inner positioning plate to clamp and fix the steel reinforcement according to the drawing requirements, thereby achieving precise positioning of the steel reinforcement. This eliminates the need to rely on the workers' experience, effectively ensuring the accuracy of the steel reinforcement cage tying and solving the problem of low installation accuracy caused by manual positioning of the steel reinforcement cage in existing box culverts.

[0028] Furthermore, the connecting plate includes a base plate 2 and a fixing bolt 3. The base plate 2 is slidably connected to the fixing bolt 3 and is located outside the fixing bolt 3. The fixing bolt 3 is threadedly connected to the base plate 2 and passes through the base plate 2.

[0029] In this embodiment, the base plate 2 provides installation conditions for the outer positioning plate and the inner positioning plate. The base plate 2 can slide on the positioning post 1 to adjust the width of the steel reinforcement cage, which is suitable for construction with different requirements. The fixing bolt 3 is used to fix the base plate 2 on the fixing bolt 3.

[0030] Furthermore, the outer positioning plate includes a horizontal plate 4 and a fixing head. The horizontal plate 4 is fixedly connected to the base plate 2 and is located on one side of the base plate 2. The fixing head is disposed on the top of the horizontal plate 4. The fixing head includes a mounting base 5 and a latch 6. The mounting base 5 has a slot 7, which is located on the top of the mounting base 5. The latch 6 is slidably connected to the mounting base 5 and is located on the side away from the horizontal plate 4.

[0031] In this embodiment, the horizontal plate 4 provides installation conditions for the fixing head and abuts against the outside of the workpiece rebar. It cooperates with the inner positioning plate to fix the rebar and realize the positioning of the rebar. The sliding bolt 6 and the slot 7 lock and fix the rebar placed in the mounting seat 5 to prevent the rebar from sliding and facilitate workers to tie the rebar mesh and rebar skeleton.

[0032] Furthermore, the inner positioning plate includes a clamping plate and a spring 8. The clamping plate is slidably connected to the base plate 2 and is located near the side of the horizontal plate 4. The spring 8 is fixedly connected to the clamping plate and the base plate 2 respectively and is located between the base plate 2 and the clamping plate. The inner positioning plate also includes a telescopic rod, which is disposed inside the spring 8. In this embodiment, the spring 8 pushes the clamping plate to abut against the reinforcing bar from the inside, and works with the horizontal plate 4 from the outside to fix and position the reinforcing bar. The spring 8 makes the distance between the clamping plate and the horizontal plate 4 adjustable, which is suitable for reinforcing bars of different diameters. The telescopic rod prevents the spring 8 from bending or stretching, which would affect the clamping and fixing of the reinforcing bar by the clamping plate.

[0033] Furthermore, the telescopic rod includes a sliding cylinder 9 and a sliding rod 10. The sliding cylinder 9 is fixedly connected to the base plate 2 and is located on the side close to the horizontal plate 4. The sliding rod 10 is slidably connected to the sliding cylinder 9 and is located on the side close to the horizontal plate 4.

[0034] In this embodiment, the slide rod 10 slides within the slide cylinder 9 and extends and retracts together with the spring 8 to prevent the spring 8 from deflecting to the side.

[0035] Please see Figure 5Secondly, the present invention provides an integral box culvert rebar binding frame, which utilizes an integral box culvert rebar positioning device, comprising a base plate 13, a column 14, a load-bearing beam 15, and reinforcing ribs 16. The base plate 13 is fixedly connected to the positioning column 1 and is located at the bottom of the positioning column 1. The column 14 is threadedly connected to the base plate 13 and is located on the side close to the column 14. The load-bearing beam 15 is fixedly connected to the column 14 and is located on the side away from the base plate 13. The reinforcing ribs 16 are fixedly connected to the load-bearing beam 15 and the column 14 respectively and are located between the load-bearing beam 15 and the column 14.

[0036] In this embodiment, the base plate 13, the column 14 and the load-bearing beam 15 form a steel reinforcement skeleton. The column 14 supports the load-bearing beam 15. The reinforcing rib 16 forms a stable triangular structure with the load-bearing beam 15 and the column 14 to enhance the strength of the steel reinforcement skeleton.

[0037] A method for positioning and binding reinforcing bars using an integral box culvert reinforcement binding frame includes the following steps: (1) Connect the positioning column (1) and the connecting plate to form a frame structure according to the size of the box culvert; (2) Connect the outer positioning plate and the inner positioning plate to the frame respectively; (3) Place the base plate (13) at the bottom of the frame, fix the column (14) on the base plate, and then fix the load-bearing beam on the top of the column to form an internal frame structure; (4) Place the reinforcing bars on the outside of the built-in frame and use the outer positioning plate and the inner positioning plate to clamp and fix the reinforcing bars. Finally, weld the reinforcing bar nodes to obtain the reinforcing bar skeleton. (5) Sequentially disassemble the outer positioning plate, the inner positioning plate, the connecting plate, and the positioning post; (6) Hoist the welded steel reinforcement cage upwards until the height exceeds the load-bearing and fixed structure of the steel reinforcement platform, then move it horizontally out to complete the positioning and binding of the steel reinforcement cage.
