Description

Technical Field

[0001] This utility model relates to the technical field of road safety protection facilities, specifically a self-compacting concrete crash barrier. Background Technology

[0002] Concrete crash barriers are wall-type traffic safety facilities made of reinforced concrete, mainly used on highways, bridges, and other road sections. They intercept out-of-control vehicles through rigid structures, preventing them from running off the road or into the oncoming lane, while reducing the severity of accidents. Traditional concrete crash barriers are mostly cast on-site using ordinary concrete. This method has several shortcomings: First, the compaction is insufficient, requiring manual vibration, which is labor-intensive, affects the construction period, and is prone to honeycomb and voids, thus affecting impact resistance. Second, in the event of an impact, the concrete crash barrier faces the impact directly, and the impact force cannot be dispersed to protect the concrete crash barrier, resulting in a rigid impact that does not reduce the force on the crash barrier and is highly destructive. To address these problems, the inventors have proposed a self-compacting concrete crash barrier to solve these issues. Utility Model Content

[0003] To address the problems of insufficient compaction and poor impact resistance in current concrete crash barriers, the purpose of this invention is to provide a self-compacting concrete crash barrier.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a self-compacting concrete crash barrier, comprising a cast-in-place body, wherein a reinforcing component is provided within the cast-in-place body, the reinforcing component includes a U-shaped main reinforcement bar, a horizontal plate is detachably provided on the outer side wall of the cast-in-place body, a stepped groove is provided on the side of the horizontal plate facing away from the cast-in-place body, a conical platform is detachably provided on the side of the horizontal plate facing away from the cast-in-place body, a clamping plate is fixedly connected to the side of the conical platform facing the horizontal plate, the cross-section of the clamping plate is stepped, the clamping plate corresponds to and cooperates with the stepped groove, and a buffer strip is fixedly connected to the side of the conical platform facing away from the horizontal plate.

[0005] Preferably, the sidewall of the U-shaped main reinforcement is fixedly connected with a first reinforcing rib and a second reinforcing rib. The axes of the first reinforcing rib and the second reinforcing rib are perpendicular to each other. The U-shaped main reinforcement, the first reinforcing rib, and the second reinforcing rib can form a three-dimensional steel reinforcement skeleton. The three-dimensional steel reinforcement skeleton can be used to enhance impact resistance. The cast body is cast using self-compacting concrete to form a continuous protective layer. Self-compacting concrete can achieve compaction by its own weight without mechanical vibration, thereby avoiding the problems of insufficient compaction and honeycomb and voids in traditional concrete guardrails. The outer sidewall of the horizontal plate is fixedly connected with a convex plate. The sidewall of the convex plate is provided with a through-hole. A first fastening bolt is provided on one side of the convex plate. The first fastening bolt corresponds to and cooperates with the mounting hole, and one end of the first fastening bolt extends into the cast body. After the cast body is cast and shaped, the horizontal plate is horizontal, the position of the horizontal plate is adjusted to fit the cast body, the first fastening bolt is inserted into the mounting hole and embedded into the cast body, thus completing the fixation of the horizontal plate.

[0006] Preferably, the sidewall of the horizontal plate is provided with a threaded hole, one end of which extends into a stepped groove. The sidewalls of the conical platform and the clamping plate are both provided with through holes, the through holes and the threaded holes having the same diameter and corresponding to each other. The sidewall of the buffer strip is provided with a groove, the groove corresponding to the through hole, and the groove diameter being larger than the through hole diameter. A second fastening bolt is provided on one side of the buffer strip. The shank of the second fastening bolt corresponds to and engages with the through hole and the threaded hole, and the shank end of the second fastening bolt extends into the casting body. The head of the second fastening bolt engages with the groove, thus providing support for the buffer strip. When installing the buffer strip, insert the clamping plate into the stepped groove and push the conical platform so that the threaded hole corresponds to the through hole. Then, remove the plug at the groove opening, insert the second fastening bolt into the through hole, and mate it with the threaded hole to limit and fix the conical platform. At this time, the head of the second fastening bolt is located in the groove opening. Then, install the plug in the groove opening to protect the head of the second fastening bolt and prevent moisture from corroding the head of the second fastening bolt. The buffer strip can be made of rubber or polyurethane. The buffer strip is used to disperse the impact force when it is hit. When disassembling and assembling the buffer strip, simply reverse the operation.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, the casting body is made of self-compacting concrete, thereby forming a continuous protective layer. Self-compacting concrete can achieve compaction by its own weight without mechanical vibration, thus eliminating the vibration process, shortening the construction period, and avoiding the problems of insufficient compaction and honeycomb and voids in traditional concrete guardrails. Furthermore, a reinforcing component is set in the casting body. The U-shaped main bar, the first reinforcing bar, and the second reinforcing bar in the reinforcing component can form a three-dimensional steel skeleton, thereby enhancing the impact resistance.

[0008] 2. In this utility model, a detachable buffer strip is provided on the outer wall of the cast body. When an impact occurs, the buffer strip can disperse the impact force to reduce the force on the crash barrier, thereby forming protection. The buffer strip can be disassembled and installed so that it can be replaced regularly to avoid the buffer strip aging and affecting the buffering effect. Attached Figure Description
