[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1-4 In this embodiment, a bridge culvert support structure includes a first sleeve rod 1, a second sleeve rod 3, and a top rod 5; the two sets of first sleeve rods 1 are connected by a connecting frame, the two sets of second sleeve rods 3 are connected by an installation frame, and the first sleeve rods 1 and the second sleeve rods 3 are connected by a telescopic rod 2.

[0028] Both ends of the first sleeve rod 1 and the second sleeve rod 3 are threadedly connected to threaded rods 4. The end of the threaded rod 4 away from the first sleeve rod 1 or the telescopic rod 2 is rotatably connected to a fixed rod 7. The end of the fixed rod 7 away from the threaded rod 4 is fixedly connected to a fixed plate 10. The fixed plate 10 is connected to the top rod 5 by a fixing bolt 11.

[0029] Using the above scheme, the first set of rods 1, the second set of rods 3, and the telescopic rod 2 form the main support frame. The telescopic rod can adjust the distance between the first set of rods 1 and the second set of rods 3. The rotation of the threaded rod 4 can adjust the horizontal position of the top rod 5. It can be adjusted according to the chamfer of the inner wall template of the culvert. The height and width can be adjusted to meet the different culvert width requirements. At the same time, the support can be adjusted according to the inclination of the chamfer template, so that the two sets of top rods 5 on the same side can effectively support the template.

[0030] Please see Figure 1 and Figure 3 The connecting frame includes a reinforcing rod 12 and a fixing frame 13. The two sets of first sleeve rods 1 are connected to the two sets of reinforcing rods 12. The fixing frame 13 is connected between the two sets of first sleeve rods 1 and is set between the two sets of reinforcing rods 12. The bottom of the fixing frame 13 is connected to a support rod 14, and the support rod 14 is hollow inside.

[0031] Specifically, the reinforcing rod 12 and the fixing frame 13 can enhance the stability of the support structure. In use, the two sets of first rods 1 can be moved synchronously by lifting the two ends of the support rod 14, or external tools can be inserted into the support rod 14 for movement.

[0032] Please see Figure 1 The mounting bracket includes a mounting strip 15 disposed at the bottom of the second sleeve rod 3, and an arc plate 16 connected to the top of the mounting strip 15. The arc-shaped inner wall of the arc plate 16 mates with the outer wall of the second sleeve rod 3. The arc plate 16 is welded or connected to the second sleeve rod 3 by mounting bolts.

[0033] Specifically, the installation method of the arc plate 16 can be selected according to the needs, and the second set of rods 3 can also be used on other frame structures by connecting to the existing pipe clamps.

[0034] Please see Figure 1 and Figure 4 The telescopic rod 2 includes a fixed rod 21 fixedly connected to the second sleeve rod 3 and a movable rod 22 fixedly connected to the first sleeve rod 1. The movable rod 22 is slidably disposed inside the fixed rod 21. A positioning bolt 23 is threadedly connected to one end of the top of the fixed rod 21. The movable rod 22 is provided with a plurality of positioning holes 24 that are threadedly engaged with the positioning bolt 23.

[0035] Specifically, when adjusting the distance between the first sleeve rod 1 and the second sleeve rod 3, the movable rod 22 slides within the fixed rod 21. After adjustment to the target position, the positioning bolt 23 can be screwed into the corresponding positioning hole 24 to restrict the sliding of the fixed rod 21, thus completing the adjustment of the distance between the first sleeve rod 1 and the second sleeve rod 3.

[0036] Please see Figure 2The threaded rod 4 has a rotating groove 6 at its end for fixing the rod 7 to rotate. A limiting ring 8 is fixedly connected to the outer wall of the fixing rod 7. An annular groove 9 for the limiting ring 8 to rotate is provided in the rotating groove 6. The cooperation between the limiting ring 8 and the annular groove 9 prevents the fixing rod 7 from coming out and ensures rotational safety.

[0037] Please see Figure 2 The first sleeve rod 1 and the telescopic rod 2 are both arranged in parallel, and the top rod 5 is arranged perpendicular to the first sleeve rod 1 or the telescopic rod 2.

[0038] Furthermore, the top rod 5 is a round tube, which combines lightweight and bending strength.

[0039] Working principle: The first set of rods 1, the second set of rods 3, and the telescopic rod 2 form the main support frame. When adjusting the distance between the first set of rods 1 and the second set of rods 3, the movable rod 22 slides within the fixed rod 21. After adjustment to the target position, the positioning bolt 23 can be screwed into the corresponding positioning hole 24 to restrict the sliding of the fixed rod 21, thus completing the adjustment of the distance between the first set of rods 1 and the second set of rods 3. The rotation of the threaded rod 4 can adjust the horizontal position of the top rod 5, which can be adjusted according to the chamfer of the culvert inner wall template. The height and width can be adjusted to adapt to different culvert width requirements. At the same time, the support can be adjusted according to the inclination of the chamfer template, so that the two sets of top rods 5 on the same side can effectively support the template.

[0040] The materials of the internal components of the support structure in this application can be selected according to actual needs, such as low alloy steel.

[0041] Example 2

[0042] Please see Figure 5 The difference from Embodiment 1 is that the ends of the first sleeve rod 1 and the second sleeve rod 3 are both threaded with reinforcing bolts 25. The horizontal position of the top rod 5 can be adjusted by rotating the threaded rod 4. During adjustment, the reinforcing bolts 25 are rotated away from the threaded rod 4. After the threaded rod 4 is rotated and adjusted, the reinforcing bolts 25 can be turned so that the reinforcing bolts 25 contact the threaded rod 4 to achieve the reinforcing effect.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
