Description

Technical Field

[0001] This utility model relates to the field of highway guardrails, and in particular to a highway guardrail that can prevent collisions. Background Technology

[0002] Highway guardrails are an important component of highway traffic facilities. They play a crucial role in ensuring driving safety and reducing traffic accident losses. When an accident vehicle collides with a guardrail, the guardrail absorbs the collision energy by blocking, deforming itself, or allowing the vehicle to climb, thus playing a buffering and guiding role.

[0003] Existing highway guardrails typically rely on the structural strength of the posts and guardrail panels themselves to prevent accident vehicles from running off the track. However, depending on the size of the vehicle, the structural strength of the posts and guardrail panels is insufficient to support the impact of larger vehicles.

[0004] Therefore, in view of the fact that the structural strength of the posts and guardrails is insufficient to support the impact of larger vehicles due to their different sizes, a highway guardrail with anti-collision function can be designed. By installing a supporting anti-collision structure at the rear end of the guardrail, the structural strength of the highway guardrail can be increased, thereby facilitating the solution of the above problems. Utility Model Content

[0005] To overcome the problem that existing highway guardrails typically rely on the structural strength of the posts and guardrail panels themselves to prevent accident vehicles from running off the track, the structural strength of the posts and guardrail panels is insufficient to support the impact of larger vehicles, depending on the size of the vehicle.

[0006] The technical solution of this utility model is as follows: a highway guardrail for preventing collisions, comprising a concrete base, support piles, guardrail panels, a first support rod and a second support rod. Support piles are provided on both sides of the concrete base, and a guardrail panel is erected between the two sets of support piles. A collision-resistant support plate is provided at the center of the rear end face of the guardrail panel, and load-bearing support rods are provided on both sides of the rear end face of the collision-resistant support plate. Fixed support rods are provided on both sides of the rear end face of the concrete base, and a connecting block is provided between the end of the fixed support rod away from the concrete base and the end of the load-bearing support rod away from the collision-resistant support plate.

[0007] Preferably, this application combines guardrail panels, support piles, crash barriers, load-bearing struts, and fixed struts, so that when an accident vehicle hits the highway guardrail, the support piles support the guardrail panel to initially block the accident vehicle, while the crash barriers press against the rear end of the guardrail panel to prevent the accident vehicle from breaking through the guardrail panel, and the load-bearing struts and fixed struts form a triangular structure at the rear end of the crash barriers to further support and prevent impact.

[0008] Preferably, a connecting seat is provided on both sides of the rear end face of the guardrail, and a movable connecting hole is provided on both sides of the connecting seat. The connecting seat is matched with two sets of arc-shaped fixing plates, and a movable connecting shaft with a corresponding movable connecting hole is provided at the far end of the two sets of arc-shaped fixing plates.

[0009] Preferably, both sets of arc-shaped fixed near ends are provided with locking blocks, and the surfaces of the two sets of locking blocks are linearly provided with three sets of locking holes.

[0010] Preferably, the corners of the anti-collision support plate are provided with mounting holes, and the rear end face of the guardrail plate is provided with four sets of reinforcement holes corresponding to the mounting holes.

[0011] Preferably, a reinforcing strut is installed between the two sets of connecting blocks, and an L-shaped connecting plate is provided at the end of the fixed strut away from the connecting block. The rear and upper surfaces of the L-shaped connecting plate are provided with secondary base fixing holes, and the rear and upper edges of the concrete base are provided with primary base fixing holes corresponding to the secondary base fixing holes.

[0012] Preferably, the end of the fixed strut away from the concrete base and the end of the load-bearing strut away from the anti-collision plate are fixedly connected by a connecting block, and the fixed strut and the load-bearing strut are arranged in a triangle.

[0013] Preferably, the upper end of the support pile is provided with a circumferential fixing groove corresponding to the arc-shaped fixing plate.

[0014] The beneficial effects of this utility model are as follows: Compared with the highway guardrails currently on the market, the structural strength of the posts and guardrail panels themselves is insufficient to support the impact of larger vehicles, depending on the size of the vehicle. This application combines guardrail panels, support posts, anti-collision plates, load-bearing struts, and fixed struts. When an accident vehicle hits the highway guardrail, the support posts support the guardrail panel to initially block the accident vehicle. At the same time, the anti-collision plates are placed against the rear end of the guardrail panel to prevent the accident vehicle from breaking through the guardrail panel. The load-bearing struts and fixed struts form a triangular structure at the rear end of the anti-collision plates to further support the anti-collision performance, thereby enhancing the structural stability and anti-collision strength of the guardrail.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment: a highway guardrail for preventing collisions, including a concrete base 1, support piles 2, guardrail panels 3, a first support rod and a second support rod. Support piles 2 are provided on both sides of the concrete base 1. Guardrail panels 3 are erected between the two sets of support piles 2. A collision-resistant support plate 6 is provided at the center of the rear end face of the guardrail panel 3. Force-bearing support rods 5 are provided on both sides of the rear end face of the collision-resistant support plate 6. Fixed support rods 4 are provided on both sides of the rear end face of the concrete base 1. A connecting block 16 is provided between the end of the fixed support rod 4 away from the concrete base 1 and the end of the force-bearing support rod 5 away from the collision-resistant support plate 6.

[0023] Please see Figures 1-3 In this embodiment, a connecting seat 10 is provided on both sides of the rear end face of the guardrail 3. A movable connecting hole 11 is provided on both sides of the connecting seat 10. The connecting seat 10 is matched with two sets of arc-shaped fixing plates 12. The ends of the two sets of arc-shaped fixing plates 12 that are far apart are provided with movable connecting shafts 14 corresponding to the movable connecting holes 11. The ends of the two sets of arc-shaped fixing plates 12 that are close to each other are provided with locking blocks 13. Three sets of locking holes 15 are linearly opened on the surface of the two sets of locking blocks 13. The upper end of the support pile 2 is provided with a circumferential fixing groove 7 corresponding to the arc-shaped fixing plate 12. During installation, the workers can rotate the two sets of arc-shaped fixing plates 12 along the movable connecting holes 11 through the movable connecting shafts 14, so that the two sets of arc-shaped fixing plates 12 wrap around the circumferential fixing groove 7 of the support pile 2. Then, the guardrail 3 and the support pile 2 are installed and connected by bolts passing through the locking holes 15 of the locking blocks 13 and fixing with nuts.

[0024] Please see Figures 3-5In this embodiment, mounting holes 9 are provided at the corners of the anti-collision support plate 6, and four sets of reinforcement holes 20 corresponding to the mounting holes 9 are provided on the rear end face of the guardrail plate 3. A reinforcement support rod 17 is provided between the two sets of connecting blocks 16. An L-shaped connecting plate 18 is provided at the end of the fixed support rod 4 away from the connecting block 16. A secondary base fixing hole 19 is provided on both the rear end surface and the upper end surface of the L-shaped connecting plate 18. A primary base fixing hole 8 corresponding to the secondary base fixing hole 19 is provided at the edge of the rear end face and the edge of the upper end face of the concrete base 1. The end of the fixed support rod 4 away from the concrete base 1 and the end of the load-bearing support rod 5 away from the anti-collision support plate 6 are fixed by the connecting block 16. The fixed connection, with the fixed support rod 4 and the load-bearing support rod 5 arranged in a triangle, is combined through the mounting hole 9 and the reinforcement hole 20. This allows workers to screw the bolts from the mounting hole 9 of the crash barrier plate 6 into the reinforcement hole 20 of the guardrail plate 3 to complete the installation of the crash barrier plate 6. Then, the bolts are passed through the secondary base fixing hole 19 of the L-shaped connecting plate 18 and the primary base fixing hole 8 of the concrete base 1, so that the load-bearing support rod 5 and the fixed support rod 4 form a triangular structure at the rear end of the crash barrier plate 6 to further support and prevent impact. At the same time, the reinforcement support rod 17 provides support and reinforcement between the two sets of load-bearing support rods 5 and the two sets of fixed support rods 4.

[0025] During the work, the workers first rotate the two sets of arc-shaped fixing plates 12 along the movable connecting holes 11 through the movable connecting shaft 14, so that the two sets of arc-shaped fixing plates 12 wrap around the circumferential fixing groove 7 of the support pile 2. Then, the guardrail plate 3 and the support pile 2 are installed and connected by bolts passing through the locking holes 15 of the locking block 13 and fixing with nuts.

[0026] Then, the workers screwed the bolts from the mounting holes 9 of the crash barrier plate 6 into the reinforcement holes 20 of the guardrail plate 3 to complete the installation of the crash barrier plate 6. Then, the bolts were passed through the secondary base fixing holes 19 of the L-shaped connecting plate 18 and the primary base fixing holes 8 of the concrete base 1, so that the load-bearing struts 5 and the fixed struts 4 form a triangular structure at the rear end of the crash barrier plate 6 to further support and prevent impact. At the same time, the reinforcement struts 17 provide support and reinforcement between the two sets of load-bearing struts 5 and the two sets of fixed struts 4.

[0027] Through the above steps, this application combines guardrail plate 3, support pile 2, anti-collision support plate 6, load-bearing support rod 5 and fixed support rod 4, so that when an accident vehicle hits the highway guardrail, the support pile 2 supports the guardrail plate 3 to initially block the accident vehicle, while the anti-collision support plate 6 is placed against the rear end of the guardrail plate 3 to prevent the accident vehicle from breaking through the guardrail plate 3. The load-bearing support rod 5 and the fixed support rod 4 form a triangular structure at the rear end of the anti-collision support plate 6 to further support the anti-collision performance and enhance the stability and anti-collision strength of the guardrail structure.
