Description

Technical Field

[0001] The utility model relates to the technical field of road guardrails, in particular to a guardrail for municipal roads. Background Art

[0002] The protective guardrails on municipal roads are suitable for isolating urban traffic arteries. Since the distance of straight roads is generally long, split guardrails are usually used or split guardrails are fastened to each other and installed at the center line of the road to effectively separate the opposite lanes.

[0003] Its structure generally includes columns, beams, and plates. The columns are the supporting part of the guardrail. The columns are fixed to the ground by anchors to ensure the stability of the entire guardrail system. The beams are the parts connecting the columns. They are usually made of steel pipes or steel plates and play a connecting and supporting role. The plates are an important part of the guardrail. They cover between the columns and beams to form a complete barrier.

[0004] However, when such guardrails are hit by a vehicle in an accident, the crossbeam bears the impact of the car, which can easily cause excessive stress at the connection between the crossbeam and the column and cause breakage. The crossbeam fails to effectively block the vehicle and can easily intrude into the cockpit of the car, causing injury to the driver. Utility Model Content

[0005] In order to solve the above technical deficiencies, the utility model provides a municipal road guardrail which has energy absorption function and is not easy to fall apart.

[0006] The utility model discloses a municipal road guardrail, comprising a base, a first metal plate is vertically arranged on one side of the base, a second metal plate is vertically arranged on the other side of the base, the upper end of the first metal plate is connected to the upper end of the second metal plate by a connecting piece, a first threading seat is arranged at intervals from bottom to top on the side of the first metal plate away from the second metal plate, a first threading hole is vertically arranged on the first threading seat, a second threading seat is arranged at intervals from bottom to top on the side of the second metal plate away from the first metal plate, and a second threading hole is vertically arranged on the first threading seat. A No. 2 threading hole is vertically arranged on the wire seat, the No. 1 threading seat and the No. 2 threading seat are staggered with each other, a No. 1 fixing seat is arranged at the lower end of the No. 1 metal plate, and a No. 2 fixing seat is arranged at the upper end of the No. 2 metal plate, the bases are fixed on the road surface at intervals and the No. 1 metal plate and the No. 2 metal plate on adjacent bases are opposite, one end of the metal rope is fixed to the No. 1 fixing seat on the No. 1 metal plate, and the other end of the metal rope is fixed to the No. 2 fixing seat on the adjacent No. 2 metal plate after passing through the No. 2 threading seat and the No. 1 threading seat on the adjacent bases in sequence.

[0007] The principle of the utility model is that when a vehicle collides with a metal rope, the metal rope intercepts the vehicle. When the impact force is large, the No. 1 metal plate and the No. 2 metal plate on the adjacent bases are deformed to absorb energy to prevent the metal rope from breaking. When the No. 1 metal plate and the No. 2 metal plate on the adjacent bases are deformed to a certain extent, the adjacent metal ropes will be tightened and participate in the force through the connecting parts to pull the colliding vehicle.

[0008] In order to allow adjacent metal ropes to better participate in the force when cars collide, a connecting rope is suspended between metal plate No. 1 and metal plate No. 2 on the same base, with one end of the connecting rope connected to the middle of metal plate No. 1, and the other end of the connecting rope connected to the middle of metal plate No. 2. When metal plate No. 1 and metal plate No. 2 on adjacent bases are deformed to a certain extent, the connecting rope is straightened, and the adjacent metal ropes are tightened to participate in the force through the connecting parts and the connecting ropes to hold the colliding vehicle.

[0009] Furthermore, in order to facilitate the adjustment of the tightness of the metal rope, an adjustment device is provided between the metal rope and the second fixing seat.

[0010] Preferably, the adjusting device is a turnbuckle tensioner, one end of which is connected to the metal rope, and the other end of which is connected to the No. 2 fixing seat.

[0011] The utility model provides a municipal road guardrail, which has the beneficial effect that when an accident occurs, the impacting vehicle is held back by the metal rope, and the No. 1 metal plate and the No. 2 metal plate absorb energy by deformation, while preventing the metal rope from being broken; when the No. 1 metal plate and the No. 2 metal plate on the adjacent bases are deformed to a certain extent, the adjacent metal ropes will be tightened and participate in the force, thereby further holding back the impacting vehicle, and the overall structure is not easy to fall apart, and the safety factor is high.
