[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0021] Reference Figure 1 and Figure 2As shown, bridge steel is a steel plate specially used for building railway or highway bridges. It is required to have high strength, toughness, and be able to withstand the load and impact of locomotives and vehicles, and to have good fatigue resistance, certain low-temperature toughness and atmospheric corrosion resistance. Bridge steel is also divided into rectangular steel and cylindrical steel. Rectangular steel is mostly used for bridge construction and bearing, while cylindrical steel is often used for bridge guardrails due to its aesthetics. At present, most of the cylindrical bridge steels used in the market are simple cylindrical tubes, which are often deformed and damaged by vehicle collisions, have poor strength, and high maintenance costs. Only damaged guardrails can be recycled. In order to solve the above problems, an anti-deformation bridge steel structure is proposed, including a cylindrical steel pipe 1 and a through groove 11 opened in the cylindrical steel pipe 1. The through groove 11 is set along both sides of the axial direction of the cylindrical steel pipe 1, and a support member 2 is provided in the through groove 11. The support member 2 includes a support column 21 and a plurality of support frames 22 distributed in an array on the outer periphery of the support column 21. A limiting slider 221 is provided on the end of the support frame 22 away from the support column 21, and a guide slide groove 12 for the limiting slider 221 to be inserted is opened in the inner wall of the through groove 11, and a plurality of the guide slide grooves 12 correspond one to one with a plurality of the limiting sliders 221, and a reinforcement member for strengthening the support column 21 is also provided in the support column 21; through the arrangement of the cylindrical steel pipe 1 and the internal support member 2, the strength of the cylindrical steel pipe 1 itself can be further improved, and the connection and arrangement between the two by means of a sleeve is more convenient, and it can also facilitate the subsequent replacement of the internal support member 2; through the arrangement of the support column 21, the support frame 22 and the limiting slider 221, the purpose of making the support column 21 inserted into the cylindrical steel pipe 1 in an orderly manner can be achieved, and the purpose of ensuring the relative stability of the support member 2 in the through groove 11 is ensured by the arrangement of the guide slide groove 12, and the anti-deformation ability of the cylindrical steel pipe 1 can be further improved by the arrangement of the reinforcement member.

[0022] It should be noted that after the cylindrical steel pipe 1 is installed, the support member 2 can be inserted into the cylindrical steel pipe 1, presenting a detachable connection state, and when the support member 2 is inserted into the through groove 11, a relatively stable anti-deformation structure is formed inside the cylindrical steel pipe 1. Since the interior has a higher strength, a relatively stable anti-deformation effect is formed on the outside of the cylindrical steel pipe 1.

[0023] Furthermore, in order to ensure the strength requirement of the above-mentioned support member 2, in this embodiment, the support column 21, the support frame 22 and the limit slider 221 are integrally arranged; the integrated arrangement can achieve better stability among the above-mentioned three, and the three can use steel to further ensure their own strength.

[0024] Additionally, the detachable connection arrangement of the cylindrical steel tube 1 and the internal support member 2 can also ensure that the damaged support member 2 can be replaced later;

[0025] In the internal structure of the cylindrical steel pipe 1, the guide groove 12 on the inner wall of the through groove 11 is not completely open, and it has a certain limit to prevent the support member 2 from sliding too far in the through groove 11, causing the internal support structure to fail.

[0026] It should also be noted that the specific structure of the above-mentioned reinforcement member is as follows: the reinforcement member includes a reinforcement groove 211 opened in the support column 21, and an array of slots 2111 are opened on the inner wall of the reinforcement groove 211. The reinforcement groove 211 is detachably connected with reinforcement ribs for strengthening the strength of the support column 21; the structure of the support column 21 can be further protected and strengthened by the provision of the reinforcement ribs, and the outer periphery of the reinforcement ribs is raised to form a convex block corresponding to the slot 2111. When the convex block slides into the slot 2111, the reinforcement rib is located inside the support column 21, so that the support column 21 is strengthened. The purpose of such a provision is also to strengthen the strength of the entire cylindrical steel pipe 1.

[0027] Furthermore, the support column 21 is arranged concentrically with the cylindrical steel pipe 1; by setting the center of the circle, it can be ensured that the support column 21 and the support frame 22 are relatively uniform in force, making their own strength more stable.

[0028] Additionally, in order to save steel consumption, in the present embodiment, the support frames 22 are spaced apart and distributed, and in order to ensure the anti-deformation strength of the support frames 22, in the present embodiment, compression rods 23 for enhancing the anti-deformation capability are provided between the two support frames 22; the provision of the compression rods 23 can further ensure that the entire support member 2 has a better anti-deformation effect and is relatively stable.

[0029] It should be noted that the compression rod 23 and the support frame 22 are integrally arranged, or connected by spot welding, so as to achieve the purpose of connecting two support frames 22.

[0030] It is worth mentioning that in order to prevent the entire support member 2 from being damaged during the process of being inserted into the cylindrical steel pipe 1, in this embodiment, a protective pad 13 is also provided on the inner wall of the through groove 11 to protect the support column 21 from sliding in; the provision of the protective pad 13 can ensure that the entire support member 2 slides into the through groove 11 in an orderly manner.

[0031] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
