What is a blocking block？
The anti-blocking block is a kind of traffic safety product, which is suitable for the use of highways. The main purpose of the anti-blocking block is to match with the guardrail and the column cap, etc., to reduce the collision behavior that occurs on the highway. Product features of anti-blocking block: hot-dip galvanized electrostatic spraying anti-blocking block, using double anti-corrosion treatment, inner coating is hot-dip galvanizing, surface coating is all polyester powder coating, and electrostatic spraying method is used to make it firmly and substrate. combined into one.
Anti-collision wave guardrail
The anti-blocking block is a part of the highway wave guardrail, which is used for the safety protection of the fence decoration in the transportation industry. The corrugated beams are spliced with each other by splicing bolts, and are fixed on the bracket anti-blocking block by connecting bolts. The overlapping direction of the corrugated beam of the roadbed guardrail is the key to the installation, and the installation should be carried out strictly according to the drawings. The lap direction should be the same as the driving direction.
The anti-blocking block of the corrugated beam guardrail is the load-bearing part between the corrugated beam and the column, which can be made of various shapes of steel. It can be divided into A-type and B-type. A-type is suitable for round columns and is a hexagonal structure; B-type is suitable for slot-shaped columns or other steel columns.
After adding the anti-blocking block between the wave beam and the column, there are many advantages:
1. The anti-blocking block itself is an energy-absorbing mechanism, so the guardrail can be gradually deformed after being collided, which is conducive to energy absorption and reduces occupant casualties;
2. The anti-blocking block is fixed between the column and the corrugated beam, so that the corrugated beam is suspended from the column. Once the out-of-control vehicle collides with the guardrail, the front wheel will not trip at the column because the corrugated beam is close to the column. ;
3. After the anti-blocking block participates in the overall function of the guardrail, the collision force can be distributed to more span structures, so that the force of the guardrail is more uniform, and the collision trajectory of the guardrail is smoother, which is conducive to the guidance of the vehicle and the overall strength of the guardrail. ;
4. When there are curbs with anti-blocking blocks, the distance between the corrugated beam and the curb surface can be reduced, and the adverse effects on the guardrail caused by the uncontrolled vehicle jumping up after hitting the curb can be reduced or even eliminated.
