[0002] Traffic signs are very important traffic engineering facilities in guiding road users, especially drivers who are not familiar with the road network. Traffic signs can provide timely and accurate information for drivers and reasonably guide them to drive normally. Therefore, relevant traffic signs must be set at key positions on the road.

[0003] The columns of traffic signs are generally set on the roadside. When an out-of-control vehicle rushes out of the road and hits the column of the traffic sign, certain damages will be caused to the accident vehicle, personnel and traffic sign. For sections with relatively high danger, guardrails need to be set to prevent out-of-control vehicles from rushing out of the road in relatively dangerous sections on the roadside, so as to avoid secondary accidents and reduce the damage degree of the accident vehicle, personnel and the structure outside the guardrail. In the sections where traffic signs are set on the road, corresponding guardrails can be set to strengthen the protection.

[0004] Most corrugated steel guardrails are constructed earlier than road traffic signs. Therefore, when constructing columnar road traffic signs, it is necessary to re-dig the road surface foundation to meet the requirements of the burial depth and firmness of the support columns on the columnar road traffic signs. The construction difficulty is great. Especially between two corrugated steel guardrails in the middle of the road, the construction difficulty of fixedly installing columnar road traffic signs is even greater, which seriously restricts the installation efficiency of columnar road traffic signs, the construction cost is high, and the construction time of columnar road traffic signs is long. The construction personnel are exposed to the middle of the road for a long time during construction, and the potential safety hazards are relatively large. For this reason, the utility model provides a fixing structure for a column body on a columnar traffic sign in order to solve the problem of difficult construction of columnar road traffic signs.
