Description

Technical Field

[0001] The utility model relates to the technical field of road guardrails, and particularly relates to a lane isolation guardrail. Background Art

[0002] The median isolation guardrail on the road is mainly set to prevent pedestrians and vehicles from crossing the road casually without following traffic rules, providing safety guarantees for the driving of pedestrians and vehicles. It separates the road in the upward direction from the road in the downward direction, preventing the upward vehicles or downward vehicles from occupying each other's lanes and causing traffic accidents such as scratches and collisions. At the same time, it is also used as a barrier to prevent citizens from casually crossing the road, avoiding traffic jams when pedestrians cross the road arbitrarily, and in severe cases, traffic accidents such as being injured or run over by vehicles.

[0003] Currently, most of the guardrails adopted are installed and used by directly placing them on the road surface. The guardrails are connected to each other to provide support. This method is prone to displacement when touched by vehicles or even pedestrians on the road, and the reliability of the guardrail installation and application is not high. Moreover, the currently adopted guardrails have a relatively small horizontal length, and the light irradiated by the vehicle lights on one side of the road is easy to pass through the guardrail and overlap with the lights of the vehicles on the other side, affecting the comfort and safety of driving. Summary of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a lane isolation guardrail, which is used to solve the problems of low reliability in installing the guardrail by directly placing it on the road surface in the prior art, and the relatively small horizontal length of the currently adopted guardrail, resulting in poor effect of blocking vehicle lights.

[0005] To achieve the above purpose and other related purposes, the present utility model provides a lane isolation guardrail, which includes two parallel distributed vertical frames. An upper crossbar and a lower crossbar are arranged between the two vertical frames. A plurality of parallel and evenly arranged partition plates are arranged between the upper crossbar and the lower crossbar;

[0006] A steel plate is provided at the lower end of the vertical frame, and the steel plate is embedded in the road surface;

[0007] Anchor bars and hexagonal steels are welded at the lower end of the steel plate, and both the anchor bars and the hexagonal steels are buried underground;

[0008] Internal threads are provided in the hexagonal steel, and a detachable bolt is threadedly engaged and passed through the hexagonal steel from top to bottom. The base is detachably connected to the upper end of the steel plate through the bolt.

[0009] In an embodiment of the present utility model, the partition plate is set as a cuboid structure with an extended horizontal length, and the distance between two adjacent partition plates is not greater than one-half of the horizontal length of the partition plate.

[0010] In an embodiment of the present utility model, the partition board has a hollow inner cavity.

[0011] In an embodiment of the present utility model, reflective stickers are provided at both ends of the partition board.

[0012] In an embodiment of the present utility model, the vertical frame is a rectangular frame structure, and bolts are passed through the lower end of the vertical frame.

[0013] In an embodiment of the present utility model, through holes for the bolts to pass through are provided on both sides of the lower end of the vertical frame and on the steel plate.

[0014] In an embodiment of the present utility model, a cross beam is further provided between the two vertical frames, and the cross beam is suspended above the partition board.

[0015] As described above, the roadway isolation guardrail of the present utility model has the following beneficial effects:

[0016] 1. By setting the steel plate, anchor bars, hexagonal steel and detachable bolts, the cooperation of the steel plate and the anchor bars can provide a reliable foundation for the installation of the guardrail. With the installation of the rectangular vertical frame, the reliability of the installation and application of the guardrail is effectively improved; the detachable cooperation of the bolts and the hexagonal steel can quickly disassemble and assemble the vertical frame, thus facilitating the overhaul, maintenance, disassembly and replacement of the structure of the guardrail above the road surface.

[0017] 2. By setting the partition board as a cuboid structure, the lengthened horizontal length of the partition board can increase the shielding area for the headlight irradiation, reduce or even avoid the passage of light, avoid the overlap of the two-way headlight irradiations on both sides of the road affecting the driver, and improve the comfort and safety of road driving; and the design of the hollow inner cavity of the partition board can reduce the weight of the guardrail, save materials and also reduce the vehicle collision damage.

[0018] 3. The roadway isolation guardrail provided by the present utility model can be used on roads with large traffic flow and no central green belt. The overall installation is reliable and has high strength; the cuboid partition board of the guardrail can better block the passage of the light irradiated by the vehicle, especially at night, and has a better function of preventing vehicle glare, improving the driving comfort and safety.
