Description

Technical Field

[0001] This utility model relates to the field of highway technology, and in particular to a road surface structure with speed bumps. Background Technology

[0002] Speed ​​bumps are traffic facilities installed on highways to slow down passing vehicles. They are typically yellow and black striped to attract visual attention, and slightly bulge the road surface to achieve the purpose of vehicle deceleration. They are generally installed at highway intersections, industrial and mining enterprise entrances, school entrances, residential area entrances, and other sections of road where vehicles need to slow down and where traffic accidents are prone to occur. They are a new type of traffic safety device used to reduce the speed of motor vehicles and non-motor vehicles. Speed ​​bumps are a type of vertical speed control measure; by changing the height or material of a certain section of the road, they force motor vehicles to slow down based on cardiac and physiological principles to achieve a safety purpose.

[0003] Highways often use convex speed bumps, which are prone to deformation after prolonged use, causing damage and loosening of the mounting screws and gradual breakage of the speed bumps. The repair, approval, replacement, and reinstallation of speed bumps all require a certain transition time. If the speed bumps cannot be replaced in time, they cannot provide a good deceleration effect for vehicles. Therefore, a road surface structure with speed bumps is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a road surface structure with speed bumps.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The fixed protrusions match the mating grooves.

[0010] Preferably, the positioning plate matches the first groove, the insert plate matches the second groove, and both sides of the top of the positioning plate and both sides of the top of the first groove are rounded.

[0011] Preferably, a counterweight plate is fixedly installed at the bottom of the positioning plate, and multiple equally spaced rectangular protrusions are fixedly provided on the outer walls of both sides of the positioning plate, with a rubber rim fixedly connected to the end of each rectangular protrusion.

[0012] Preferably, a plurality of equally spaced iron pieces are fixedly embedded at the bottom end of the insert plate, and the plurality of iron pieces are magnetically attracted to the magnetic plate. A right-angle groove is provided in the middle of the outer wall on both sides of each insert plate, and the right angle of the right-angle groove is located at the lower end of the insert plate, the hypotenuse of the right-angle groove is located on the inner side of the insert plate, and the baffle plate matches the hypotenuse of the right-angle groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model proposes a road surface structure with speed bumps. The roadbed top has a first groove, two second grooves, and multiple rows of fixing protrusions. The first groove is located in the middle between the two second grooves, and the multiple rows of fixing protrusions are located on both sides of the top of the two second grooves. A first warning strip and a second warning strip are located on the outside of the two second grooves. This ensures that even if the speed bump is not installed or replaced in time, vehicles will experience both physical and psychological deceleration when passing over this road surface. Furthermore, the bottom of the speed bump has a positioning plate, two insert plates, and multiple rows of connecting grooves. The fixing protrusions match the connecting grooves, the positioning plate matches the first groove, and the insert plates match the second grooves, allowing the speed bump to be installed at the top of the roadbed for better vehicle deceleration.

[0016] This utility model proposes a road surface structure with speed bumps. A counterweight plate is fixedly installed at the bottom of the positioning plate to increase the center of gravity and stability of the positioning plate. Multiple rectangular protrusions and rubber edgings fixed on the outer walls of both sides of the positioning plate are blocked by arc-shaped clips, making it difficult for the positioning plate to protrude from the first groove. Multiple iron pieces are magnetically attracted to the magnetic plate. The hypotenuse of the right-angle groove is located inside the insertion plate. The baffle plate matches the hypotenuse of the right-angle groove, making the insertion plate stably and continuously located in the second groove. This makes it difficult for the speed bump to shift under the impact of vehicle movement. Attached Figure Description

The surface of the speed bump 10 is covered with an anti-slip coating layer, and the anti-slip coating layer is made of a highly reflective coating, which allows the driver to see the speed bump 10 from a distance and slow down in advance.

[0023] In this utility model, a first warning strip 2 and a second warning strip 3 are fixedly installed at the top of the roadbed 1, and the first warning strip 2 and the second warning strip 3 are located on the outside of the two second grooves 6. The outer walls of the first warning strip 2 and the second warning strip 3 are coated with a high reflective coating.

[0024] The height of the first groove 4 is greater than the height of the second groove 6, and the width of the first groove 4 is greater than the width of the second groove 6.

[0025] Two adjacent fixed protrusions 9 are staggered, and multiple rows of fixed protrusions 9 are located on both sides of the top of the two second grooves 6. Two adjacent mating grooves 18 are staggered, and multiple rows of mating grooves 18 are located on both sides of the two insert plates 15. The fixed protrusions 9 and the mating grooves 18 are matched.

[0026] The positioning plate 11 matches the first groove 4, the insertion plate 15 matches the second groove 6, and the top two sides of the positioning plate 11 and the top two sides of the first groove 4 are both rounded.

[0027] A counterweight plate 12 is fixedly installed at the bottom of the positioning plate 11. Multiple rectangular protrusions 13 at equal intervals are fixedly provided on the outer walls of both sides of the positioning plate 11, and a rubber expansion edge 14 is fixedly connected to the end of each rectangular protrusion 13.

[0028] Multiple equally spaced iron pieces 16 are fixedly embedded at the bottom of the insert plate 15, and the multiple iron pieces 16 are magnetically attracted to the magnetic plate 7. A right-angle groove 17 is opened in the middle of the outer walls on both sides of each insert plate 15, and the right angle of the right-angle groove 17 is located at the lower end of the insert plate 15, and the hypotenuse of the right-angle groove 17 is located on the inner side of the insert plate 15. The baffle 8 matches the hypotenuse of the right-angle groove 17.

[0029] Working principle: The roadbed 1 has a first groove 4, two second grooves 6 and multiple rows of fixed protrusions 9 at the top. The first groove 4 is located in the middle between the two second grooves 6, and the multiple rows of fixed protrusions 9 are located on both sides of the top of the two second grooves 6. The first warning strip 2 and the second warning strip 3 are located on the outside of the two second grooves 6.

The bottom of the speed bump 10 is equipped with a positioning plate 11, two insert plates 15 and multiple rows of docking grooves 18. The fixed protrusions 9 match the docking grooves 18, the positioning plate 11 matches the first groove 4, and the insert plates 15 match the second grooves 6. This allows the speed bump 10 to be installed at the top of the roadbed, achieving a better deceleration effect for vehicles.

[0030] A counterweight plate 12 is fixedly installed at the bottom of the positioning plate 11 to increase the center of gravity and stability of the positioning plate 11. Multiple rectangular protrusions 13 and rubber edging 14 fixed on the outer walls of both sides of the positioning plate 11 are blocked by arc-shaped clips 5, making it difficult for the positioning plate 11 to protrude into the first groove 4. Multiple iron pieces 16 are magnetically attracted to the magnetic plate 7. The hypotenuse of the right-angle groove 17 is located inside the insert plate 15. The baffle 8 matches the hypotenuse of the right-angle groove 17, so that the insert plate 15 is stably and continuously located in the second groove 7, thereby making it difficult for the speed bump 10 to shift under the impact of vehicle movement.
