1. The speed bump should be integrally formed, and the outer surface should have stripes to increase adhesion;
2. Each speed bump unit should have reflective materials for easy identification of the vehicle's driving direction at night;
3. The rubber deceleration surface should have no pores, obvious scratches or missing materials, and the color should be uniform without flash;
4. The name of the production unit should be pressed on the surface of the speed bump;
5. If the speed reduction belt is connected to the ground through bolts, the bolt holes should be countersunk holes. Each unit of the speed bump should be connected in a reliable manner.
When installing the speed bumper, pay attention to the position of the holes:
There is a small hole in the middle of both sides of the deceleration belt, which is a mounting hole. Use expansion screws to fix the reducer on the road. Therefore, when a vehicle rolls over the reducer, the part that bears the force is the mounting hole, and the part that tears first is also the connecting hole, so the reducer falls off and the steel nails are exposed. The steel nails protruding from the road will puncture the tires. The main reason for this situation is cutting corners and using recycled rubber to add a large amount of low-cost additives, which greatly reduces the strength of the material.
To avoid this problem, we must use natural rubber instead of recycled rubber. Don't add lots of low-cost additives. The connection holes are lined with steel plates and connected to each other. When the rubber product is vulcanized, a steel plate is installed inside the speed bump to connect the two holes. The expansion screws also pass through the steel plate when installed, increasing the connection strength of the holes. There are large and small holes on the steel plate to better combine the steel plate with the rubber. Add meridians for added strength.
To sum up, when installing the speed bump, you should pay attention to the hole position, so installing the product correctly will not only play an effective role, but also better ensure the quality of the product.
Design requirements for speed bumps:
1. The width of the speed bump shall not exceed 30 cm, and the thickness (height) shall not exceed 5 cm. There are two lengths according to the width of the road surface: 25 cm and 1 meter. The belt should be covered with black and yellow stripes to distinguish the color of the road surface.
2. The speed bump is made of high-strength rubber with good compression resistance, and the slope should be soft to a certain extent without strong bumps during driving, and the shock absorption and shock absorption effects are also very good.
3. The main body of the deceleration belt is black and yellow, which is very eye-catching. High-brightness reflective beads can be installed on the end sections to reflect light at night, so that the driver can see the position of the deceleration slope.
4. Speed bumps are suitable for parking lots, residential areas, government school entrances, toll lanes and other places. Unreasonable speed bumps are not allowed to be installed at will.
