Description

Technical Field

[0001] The utility model relates to the field of assembled bridge guardrails, in particular to an assembled bridge guardrail. Background Art

[0002] Prefabricated steel bridges all include piers, columns arranged above the piers, a bridge body arranged above the columns, and guardrails arranged on both sides of the bridge body. Anti-collision guardrails are important bridge safety protection facilities, which are related to the safety of bridge operation and the safety of people's lives and property. However, during the use of existing bridge guardrails, most of them use multiple columns and multiple beams arranged between two adjacent columns to cooperate to play the role of guardrail protection. However, when the guardrail is used on the bridge, it is easy to be hit by vehicles. Most guardrails cannot buffer the impact force, so that the columns and beams directly bear all the impact force, which not only reduces the effect of the guardrail, but also reduces the service life of the guardrail. At the same time, when the bridge is damaged, the entire bridge needs to be replaced, which greatly increases the replacement cost. Utility Model Content

[0003] In order to overcome the problem that most guardrails cannot buffer the impact force during use of prefabricated bridge guardrails, the columns and beams directly bear all the impact force, which not only reduces the effect of the guardrail, but also reduces the service life of the guardrail. At the same time, when the bridge is damaged, the entire bridge needs to be replaced, which greatly increases the replacement cost.

The interior of the mounting base is provided with an assembly component for fixing the guardrail, the top of the assembly component is provided with an anti-collision component for preventing the guardrail from collision, and the anti-collision components are movably connected with a connecting component for connecting the guardrail.

[0005] Preferably, the installation of the guardrail is facilitated by the provision of the assembly components. When part of the guardrail is damaged, it is convenient to carry out corresponding replacement and repair according to the damaged part of the bridge, thereby reducing the replacement cost. At the same time, the anti-collision component buffers the impact force received when hit by a vehicle, thereby reducing the risk of vehicle damage and the probability of bridge damage, while protecting the bridge and increasing the service life of the bridge.

[0006] Preferably, the assembly components include mounting columns, partitions, a base plate, connecting grooves, and sliders. Two groups of mounting columns with mounting grooves are provided on the left and right sides of the top of the inner part of the mounting base. When installing the bridge guardrail, the connecting grooves on the base plate are aligned with the mounting columns.

[0007] Preferably, a partition is provided at the middle position of the top of the mounting base, the top of the mounting base is movably connected with a bottom plate, and the bottom plate is provided with left and right ends of the partition.

[0008] Preferably, connection grooves are provided on both sides of the left and right sides of the bottom end of the base plate, and sliders are provided inside the connection grooves, and the sliders are slidably connected to the outer sides of the partitions. When installing the bridge guardrail, the base plate is installed on the mounting base.

[0009] Preferably, the anti-collision component includes a seat, a rubber pad, a side panel, a rubber plate, a frame, and an anti-collision roller. A seat is provided at the top of the bottom plate, and rubber pads are provided on the left and right sides of the front end of the seat. When used on a bridge guardrail, the rubber pad and the rubber plate cooperate to prevent the vehicle from being scratched and damaged when it collides with the bridge guardrail, while reducing the impact degree of the vehicle.

[0010] Preferably, the interior of the stand is movably connected to the side panel through a telescopic rod, the front end surface of the side panel is provided with a rubber plate, the top of the stand is provided with a stand frame, and the front end of the stand frame is provided with four groups of anti-collision rollers in a rectangular distribution. When the bridge guardrail is used, when the impact force of the vehicle is large, the setting of the anti-collision rollers changes the travel path of the impacting vehicle, thereby buffering and dispersing the impact force of the impacting vehicle, reducing the impact force of the vehicle, thereby improving the guardrail effect and increasing the service life of the guardrail.

[0011] Preferably, the connecting assembly includes a mounting frame, a connecting frame, and connecting bolts. The mounting frame is arranged on the rear side of the top end of the seat. The connecting frame is movably connected between the mounting frames. The connecting bolts are bolted between the connecting frame and the mounting frame. When installing the bridge guardrail, the connecting frame is clamped between the mounting frames and fixed with the connecting bolts to complete the installation of the bridge guardrail.

[0012] 1. The installation of the assembly components makes it easier to install the guardrail. When the guardrail is partially damaged, it is easier to replace and repair it according to the damaged part of the bridge, thus reducing the replacement cost. At the same time, the anti-collision component buffers the impact force when it is hit by a vehicle, thus reducing the risk of vehicle damage and the probability of bridge damage. At the same time, the bridge is protected and the service life of the bridge is increased.

[0013] 2. Through the cooperation of rubber pads and rubber plates, when a vehicle rubs against the bridge guardrail, it can avoid damage to the vehicle and reduce the impact degree of the vehicle. When the impact force of the vehicle is large, the setting of the anti-collision roller changes the driving path of the impacting vehicle, thereby buffering and dispersing the impact force of the impacting vehicle, reducing the impact force of the vehicle, thereby improving the effect of the guardrail and increasing the service life of the guardrail;

[0014] 3. By matching the connecting groove on the bottom plate to the mounting column, the slider slides into the mounting groove of the mounting column, and the bottom plate is installed on the mounting base. At the same time, the connecting frame is clamped between the mounting frames and fixed with connecting bolts to complete the installation of the bridge guardrail. BRIEF DESCRIPTION OF THE DRAWINGS
