A stud 11 is arranged between the positioning block 10 and the tripod 9, and the stud 11 and the bolt 12 are components for fixation. Bolts 12 are arranged on both sides of the stud 11.

[0030] For a guardrail support frame for road and bridge design, a upper flange 13 is fixedly installed at the bottom of the positioning block 10, and screws 15 are arranged around the upper flange 13, which are installation components for the upper structure.

[0031] A guardrail support frame for road and bridge design further includes:

[0032] The main body support assembly 3, the main body support assembly 3 includes rib plates 16 arranged in an array around the periphery of the upper flange 13.

[0036] Working principle:

[0037] In the actual design process of the present utility model, in order to avoid the following defects existing in the prior art: "In the prior art, the support device of the bridge bracket mainly fixes the bridge guardrail in a fixed manner. However, the bridge guardrail may have a torsional acting force during use. If this acting force is not eliminated in time, it may cause the connection part to break, and then lead to the problem of the failure of the entire support component.", the torque buffer assembly 2 and the main body support assembly 3 are specifically proposed;

[0038] The torque buffer assembly 2 mainly inserts and installs the guardrail 1 inside the rotating tube 5. Slots 7 are evenly arranged on the inner side of the outer tube 6, and the roller 8 is embedded inside the slot 7. The roller 8 can rotate inside the slot 7, thereby promoting the rotation of the internal rotating tube 5. Once a torsional acting force appears on the surface of the guardrail 1 during use, it will directly drive the rotating tube 5 to rotate inside the outer tube 6, thereby offsetting this torsional acting force.

[0039] The main body support assembly 3:

[0040] The main body support component 3 is the main component that bears the load of this device. Among them, the rib plates 16 are installed at the bottom of the upper flange 13 in an array arrangement to achieve the effect of direct support. Multiple uniformly arranged rib plates 16 can evenly bear the load. To avoid the risk of the rib plates 16 collapsing due to excessive load during the support process, triangular struts 17 are arranged in the middle of the rib plates 16; the struts 17 can set the hollow structure in the middle of the rib plates 16 as a multi-triangular structure, and the stability of the triangle makes the rib plates 16 have greater structural strength during the support process. The lower flange 18 at the bottom is fixed to this device through bolts 19, and then this support component is installed at the required bridge part.

[0041] In this utility model, through the set torque buffer component 2, its main function is to limit and install the guardrail 1 pipe inside the rotating pipe 5; since the external outer pipe 6 is provided with rollers 8 through slots 7, and the rotating pipe 5 can rotate under the limit of the rollers 8. Once a torsional force appears at the guardrail 1 part, it can directly rotate at the rotating pipe 5 part to offset this force. It avoids the problem of torsional damage caused by rigid rotation. Through the set multi-rib plate 16 and triangular strut 17 structures, the main body support part of this device presents a multi-triangular structure; the triangular structure has stability and higher structural strength under the condition of the same material. In addition, multiple uniformly arranged rib plates 16 can evenly distribute the acting force, so that the acting force will not be concentrated on a certain part.
