Description

Technical Field

[0001] The utility model belongs to the technical field of sight guidance facilities for highways, and particularly relates to a flexible rebound sheet column type contour marker. Background Art

[0002] According to the relevant requirements of the current highway traffic safety facilities design specification, contour markers should be continuously set along the whole line of the main lines of expressways and first-class highways, their interchange intersections, service areas, parking areas, etc., the access ramps, connecting roads and escape lanes, and should also be continuously set in the opening sections of the central isolation belt. For second-class and lower-class highways, contour markers should be set in sections with poor visibility, sections with a designed driving speed greater than or equal to 60 km / h, sections with changes in the number of lanes or lane widths, and sections with continuous sharp curves and steep slopes. Contour markers can be set as needed in other sections. Usually, contour markers are attached to the roadside guardrails, but for sections without guardrails, column type contour markers are required to display the road boundary contour, guide vehicles to drive normally, and also have night retroreflective performance.

[0003] At present, most column type contour markers are made of precast cement triangular column contour markers or manganese steel sheet contour markers, but these two products have the following disadvantages: ① The precast cement column contour marker does not have rebound performance. When a vehicle hits it, the column is easy to break and cause secondary injury to the vehicle; ② Although the manganese steel sheet contour marker has a certain degree of resilience, the rebound angle is limited, and the manganese steel sheet is relatively thin. When it is hit by the side of a vehicle, the manganese steel sheet is easy to form sharp edges, similar to "steel knives", causing secondary damage to vehicles or pedestrians. Existing column type contour markers have a series of problems such as being easy to wear, easy to rust, and easy to cause secondary injury. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a flexible rebound sheet column type contour marker. According to the utility model, the stability of the column type contour marker is improved, it is ensured that the contour marker column can still maintain an upright state after being scratched or collided, the service life of the contour marker is prolonged, and the maintenance cost is reduced.

[0021] To make the purpose, technical solutions and advantages of the utility model clearer and more understandable, the following are preferred embodiments given with reference to the attached drawings, and the utility model is further described in detail. However, it should be noted that many details listed in the specification are only for the reader to have a thorough understanding of one or more aspects of the utility model, and these aspects of the utility model can be realized even without these specific details.

[0022] As Figure 1 shown, according to a flexible rebound sheet columnar profile marker provided by the present utility model, the profile marker includes a base 4 and a column body 1 provided on the base 4. The column body 1 is a flexible arc-shaped sheet, that is, a single-piece arc plate structure. A black marking area 2 is provided on the side wall of the column body 1, and a reflective layer 3 is provided in the black marking area 2. The base 4 is a hollow conical tower structure. The base 4 is a flexible base. The base 4 is a circular base or a regular polygon base (such as a square or a regular hexagon, etc.). The column body 1 and the base 4 are integrally formed. A plurality of fixing holes are provided at the edge of the base 4, and the base 4 is anchored to the ground by using bolts through the fixing holes. The distance from the reflective layer to the bottom end of the column body 1 is 55 cm to 73 cm, and the height and width dimensions of the reflective layer 3 are 180 mm × 40 mm. Both the column body 1 and the base 4 are made of a flexible material such as a combination material of highly elastic and weather-resistant modified polypropylene, and the flexible material is made of a PVC reinforced modified material, a glass fiber reinforced modified material, an SBS reinforced modified material or a PP reinforced modified material.

[0023] In the present utility model, in combination with Figure 2 and Figure 3As shown, the base 4 includes a base body 40 and a hollow conical cylinder 41 provided on the base body 40. An opening 42 for fitting and inserting the column body 1 is provided from the top to the bottom of the hollow conical cylinder 41; the diameter of the lower end of the hollow conical cylinder 41 is smaller than the diameter of the base body 40, the chord length of the column body 1 is not greater than the diameter of the base body 40, and a plurality of fixing holes 43 are provided at the edge of the base body 40; the base body 40 is anchored to the ground by using bolts in the fixing holes 43, and the column body 1 and the opening 42 of the base body 40 can be integrally formed by bonding.

[0024] In the present utility model, as Figure 3 shown, the black marking areas 2 are distributed on both the concave and convex sides of the flexible arc-shaped column body 1, and the plane formed by the black marking areas 2 is in the shape of a parallelogram after being unfolded and straightened. Reflective layers 3 are respectively provided on both sides of the black marking areas 2 on the concave and convex sides of the column body 1 along the axial center line of the column body 1. The reflective layers are provided on the outer side wall of the column body 1, and the reflective layer 3 is located at the upper and lower center positions of the black marking areas 2. The reflective grade is Class I, the colors are all white and it is a white Class V reflective film, the column body 1.

[0025] In the present utility model, as Figure 4 shown, in use, the column body 1 is symmetrically arranged on both sides of the road, and the convex side of the column body 1 faces the direction of vehicle travel. The reflective layer 3 is perpendicular to the driving direction. The height of the column body 1 is 900 mm - 1100 mm, the column thickness is not less than 4.0 mm, the chord length of the column body 1 is 110 mm ± 5 mm, and the chord height is 16 mm ± 2 mm. The present utility model integrally casts the column body 1 and the base 4 through a flexible material, improving the buffering performance of the contour marker under the action of impact loads, ensuring that the integrity of the contour marker column can still be maintained after being impacted, extending the service life of the contour marker, reducing the maintenance cost, while reducing the damage degree of the vehicle colliding with the contour marker, reducing the threat to the driver and passengers, ensuring the personal safety of the driver, and at the same time reducing the damage to the vehicle. The present utility model solves the problem that the columnar contour markers made of cement or fiberglass currently in use will not only cause different degrees of damage to the column body after being slightly scratched or collided by a vehicle and cannot be used continuously, but also cause different degrees of damage to the vehicle that has a collision. The road property maintenance department needs to replace the damaged columnar contour markers in time, increasing the operation and maintenance cost of the road, and the safety of the vehicle and the driver and passengers cannot be guaranteed. The present utility model also avoids the problem that the manganese steel sheet type contour marker currently in use will turn into a structure similar to a "steel knife" at a specific angle, threatening the safety of the driving vehicle and the driver, avoiding secondary damage after the vehicle collision, and effectively ensuring driving safety.

[0026] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.
