Description

Technical Field

[0001] The invention belongs to the field of traffic safety facilities, and in particular relates to a hinged high-damping anti-collision concrete support column. Background Art

[0002] Anti-collision concrete column is a very common road traffic safety and load-bearing structure, which can play a role of anti-collision while playing a load-bearing role. It plays a buffering role in accidental collisions with vehicles, can effectively reduce the impact force, and greatly reduce the damage to vehicles and people. Therefore, it can significantly reduce the damage to vehicles and people, has the ability to buffer the impact force, and has the characteristics of high supporting strength. It has been widely used in some areas that need to bear and are prone to collision risks, such as the turning points of the road under the bridge, the entrance and exit, and the highway with a high speed. There are safety hazards. On the one hand, it can increase the bearing capacity of the structure. On the other hand, when the vehicle collides with the anti-collision concrete column, a kind of anti-collision concrete column with buffering performance is set, which can greatly buffer the huge impact force generated by the collision, thereby greatly reducing the serious consequences of traffic collision accidents. In addition, the existing anti-collision concrete columns generally have poor buffering performance. At the same time, many anti-collision concrete columns are generally designed to be light in weight in order to achieve effective buffering and shock absorption. This does not play an effective supporting and bearing role, and is very vulnerable to external impact. It is easy to be moved and scratch passing vehicles and pedestrians, causing great safety hazards and easily causing secondary injuries. Under the huge impact force, due to its insufficient design, weak impact resistance and poor buffering performance, the existing anti-collision concrete columns are generally prone to deformation of the concrete column structure. Anti-collision concrete support columns are very necessary traffic safety infrastructure. my country's highways have been developed since the 1980s, and they play an important role in the development of the national economy and society. Anti-collision concrete columns are very important safety assurance facilities for highways, which can simultaneously play the role of supporting and anti-collision protection, and can effectively reduce the losses caused by accidents, effectively reduce the probability of vehicle damage caused by accidental collisions, reduce the probability of property losses and casualties, and protect people's lives and property from infringement to the greatest extent. Summary of the invention

The ordinary fixed hinges are connected to the high-strength fixed hinges on both sides thereof through hinge connecting rods. The high-strength fixed hinges are in contact with the high-damping rubber layers arranged on the outside thereof. A number of anti-collision protection pads are arranged on the outside of the high-damping rubber layer. Core concrete is arranged inside the structure surrounded by the high-efficiency folded energy-absorbing steel plates and the energy-absorbing tubes. Concrete filled with damping material is arranged inside the cavity surrounded by the high-efficiency folded energy-absorbing steel plates, the energy-absorbing tubes and the high-damping rubber layer.

[0012] The beneficial effects and advantages of the present invention are simplicity, practicality, safety and low cost. The anti-collision concrete support column has strong anti-collision ability, stronger elasticity and buffering ability, and stronger supporting bearing capacity. In order to enable the anti-collision concrete column to disperse the impact force of the vehicle, the energy is transmitted to the high-strength fixed hinge and the thin-walled supporting energy-consuming steel plate frame through the vehicle impacting the anti-collision protection pad and the high-damping rubber layer, which deforms and consumes energy, and can also drive the high-efficiency folding energy-consuming steel plate and the energy-consuming pipe to consume energy. The hinge connecting rod and the connection between the ordinary fixed hinge and the high-strength fixed hinge are arranged to make the coordinated connection performance of the thin-walled supporting energy-consuming steel plate frame good, and the collision force is dispersed and transmitted, which can significantly improve the energy consumption efficiency. By performing multi-layer buffering on the impact force, the degree of damage to the vehicle is reduced, and the safety performance is improved, thereby protecting the safety of the vehicle and the passengers to the greatest extent. At the same time, while ensuring shock absorption and anti-collision, it has a certain strength, effectively improves the bearing capacity, improves the anti-collision and bearing capacity of the concrete column, and meets the requirements of highway anti-collision and bearing support.
