Description

Technical Field

[0001] This utility model belongs to the technical field of wave-shaped guardrails, specifically relating to a wave-shaped guardrail that is easy to disassemble. Background Technology

[0002] Corrugated guardrails are a type of traffic safety facility widely used on highways. They consist of corrugated guardrail panels, posts, and connectors, with the posts buried underground to provide stable support.

[0003] In existing technology, the posts are integrated structures. When the guardrail is hit by a vehicle, the impact force is transmitted to the post through the guardrail panel. The impact force can easily cause the buried part of the post to bend or deform. Large equipment is needed to pull the old post out of the foundation and re-bury the new post. The maintenance and replacement work will become extremely complicated. This process is not only long and costly, but also seriously affects road traffic. Utility Model Content

[0004] This utility model provides a corrugated guardrail that is easy to disassemble, reducing the frequency of disassembly of the deeply buried posts and solid protective sections when personnel disassemble and replace the guardrail, thus reducing the workload of the staff.

[0005] This utility model provides the following technical solution: a corrugated guardrail that is easy to disassemble, comprising a corrugated guardrail body, a deeply buried post, and a ground support post. A solid protective section is fixedly connected to the top of the deeply buried post, and a solid reinforcing section is fixedly connected to the bottom of the ground support post. A distance is left between the solid protective section and the solid reinforcing section. A connecting rod is fixedly connected to the bottom of the solid reinforcing section. The connecting rod is detachably connected to the solid protective section. A primary energy-absorbing rod is detachably connected to the outer wall of the ground support post.

[0006] The corrugated guardrail body has an installation plate on its side wall, the installation plate is inclined upward, and the primary energy-absorbing rod is detachably connected to the installation plate.

[0007] The solid protective section has a bolt hole at its top, and the connecting rod is threaded into the inner wall of the bolt hole.

[0008] The solid reinforced section is fixedly connected to a hollow energy-absorbing tube at its bottom end, and the hollow energy-absorbing tube is sleeved on the outer wall of the connecting rod.

[0009] A sealing ring is fixedly connected to the bottom end of the hollow energy-absorbing tube.

[0010] The primary energy-absorbing rod is fixedly connected to a connecting plate at its bottom end, and the connecting plate is bolted to the mounting plate.

[0011] The primary energy-absorbing rod has a connecting sleeve fixedly connected to one end. The connecting sleeve is fitted onto the outer wall of the ground support column and is bolted to the ground support column.

[0012] The beneficial effects of this utility model are as follows: By using the solid protective section to wrap and reinforce the connecting rod, and with the gap reserved between the solid protective section and the solid reinforced section, the middle part of the connecting rod can be used as the stress-bearing deformation part. With the detachable connection between the solid protective section and the connecting rod, it can protect the buried deep column and the solid protective section. Furthermore, with the torsion and deformation protection of the column under stress by the primary energy-absorbing rod, it can improve the deformation resistance of the buried deep column and the solid protective section when the guardrail is impacted, reduce the frequency of disassembly of the buried deep column and the solid protective section when personnel disassemble and replace the guardrail, and reduce the workload of the staff.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0019] Please see Figures 1-4 The present invention provides the following technical solution: a corrugated guardrail that is easy to disassemble, comprising a corrugated guardrail body 1, a deeply buried post 2 and a ground support post 3. A solid protective section 21 is fixedly connected to the top of the deeply buried post 2, and a solid reinforcing section 31 is fixedly connected to the bottom of the ground support post 3. A distance is left between the solid protective section 21 and the solid reinforcing section 31. A connecting rod 32 is fixedly connected to the bottom of the solid reinforcing section 31. The connecting rod 32 is detachably connected to the solid protective section 21. A primary energy-absorbing rod 4 is detachably connected to the outer wall of the ground support post 3.

[0020] In this implementation plan: During equipment production, the wall thickness of the ground support column 3 and the buried column 2 shall not be lower than the national standard requirements. The connecting rod 32 shall be selected with a suitable diameter to provide a bending strength stronger than that of the ground support column 3. After the bolt holes 22 are opened in the solid protective section 21, the wall thickness of the solid protective section 21 shall still be greater than that of the buried column 2 and the ground support column 3 to effectively protect the part of the connecting rod 32 inserted into the solid protective section 21 and limit the bending deformation of the part of the connecting rod 32 inserted into the solid protective section 21.

[0021] During the installation of the guardrail, the deep-buried post 2 and the solid protective section 21 are first buried in the ground. The deep-buried post 2 is completely buried in the ground, and the top of the solid protective section 21 protrudes from the ground. The deep-buried post 2 is wrapped and protected by compacting the surrounding soil or pouring concrete to increase its bending strength. Then, the connecting rod 32 is threaded into the inner wall of the bolt hole 22 until the bottom of the sealing ring 34 is tightly fitted with the top of the solid protective section 21. Then, the connecting sleeve 42 is fitted onto the outer wall of the ground support post 3, and the connecting sleeve 42 and the ground support post 3 are fixed with bolts. After that, the corrugated guardrail body 1 is lifted and aligned with the connecting plate 41, and the mounting plate 11 and the connecting plate 41 are fixed with bolts.

[0022] When the guardrail is hit by a vehicle, the corrugated guardrail body 1 and mounting plate 11, after being impacted, act on the primary energy-absorbing rod 4, and then exert force on the ground support column 3, solid reinforcement section 31, connecting rod 32, deep-buried column 2, and solid protective section 21. The ground support column 3 and the primary energy-absorbing rod 4 are the weakest points in terms of bending strength, and they deform first, absorbing the energy of the vehicle impact. When the impact force is large, the ground support column 3 further transmits the force to the connecting rod 32. With the reinforcement of the connecting rod 32 by the solid protective section 21 and the reinforcement of the connection between the ground support column 3 and the connecting rod 32 by the solid reinforcement section 31, the bending strength of the two ends of the connecting rod 32 is greater than that of the corresponding hollow energy-absorbing tube 33. The part where the connecting rod 32 is inserted into the solid protective section 21 will deform before the solid protective section 21 deforms. At this time, when the staff disassembles the guardrail, they only need to remove the connecting rod 32 from the solid protective section 21 and replace the upper structure. The buried column 2 and the solid protective section 21 can still be used. It is not necessary to remove the buried column 2 and the solid protective section 21 every time the guardrail is impacted and deformed. It is not necessary to use large equipment to remove and replace the buried column 2 and the solid protective section 21 buried underground. The part where the connecting rod 32 is inserted into the solid protective section 21 remains undeformed. By rotating the ground support column 3, the solid reinforcement section 31 and the connecting rod 32, the connecting rod 32 can be easily taken out from the bolt hole 22, which can effectively reduce the workload of disassembling and replacing the guardrail.

[0023] If the impact force is too great, causing the connecting rod 32 to exert force on the buried column 2 and the solid protective section 21, resulting in deformation of the buried column 2 and the solid protective section 21, the buried column 2 and the solid protective section 21 shall be disassembled and replaced.

[0024] The corrugated guardrail body 1 has a mounting plate 11 on its side wall. The mounting plate 11 is inclined upwards, and the primary energy-absorbing rod 4 is detachably connected to the mounting plate 11. By setting the mounting plate 11, it can match the inclination angle of the primary energy-absorbing rod 4, so that the corrugated guardrail body 1 can be vertically distributed. When the corrugated guardrail body 1 is hit by a vehicle, the corrugated guardrail body 1 and the mounting plate 11 apply a force to the primary energy-absorbing rod 4. The primary energy-absorbing rod 4 can bend and twist under the force, and absorb and convert the energy of the vehicle impact through the deformation of the primary energy-absorbing rod 4.

[0025] The top of the solid protective section 21 has a bolt hole 22, and the connecting rod 32 is threaded into the inner wall of the bolt hole 22; by setting the bolt hole 22, it is easy to connect the connecting rod 32 to the solid protective section 21.

[0026] A hollow energy-absorbing tube 33 is fixedly connected to the bottom end of the solid reinforced section 31. The hollow energy-absorbing tube 33 is sleeved on the outer wall of the connecting rod 32. By setting the hollow energy-absorbing tube 33, the exposed section of the connecting rod 32 can be shielded and protected. Moreover, the deformation of the hollow energy-absorbing tube 33 can further absorb energy and improve the protection effect.

[0027] A sealing ring 34 is fixedly connected to the bottom end of the hollow energy-absorbing tube 33; by setting the sealing ring 34, a sealing function can be achieved, and in conjunction with the hollow energy-absorbing tube 33, it can cover the bolt hole 22 to prevent rainwater from entering the bolt hole 22 and causing the internal threads of the bolt hole 22 to rust.

[0028] A connecting plate 41 is fixedly connected to the bottom end of the primary energy-absorbing rod 4, and the connecting plate 41 is bolted to the mounting plate 11; by setting the connecting plate 41, it is easy to connect the mounting plate 11 and the primary energy-absorbing rod 4.

[0029] One end of the primary energy-absorbing rod 4 is fixedly connected to a connecting sleeve 42, which is fitted onto the outer wall of the ground support column 3 and bolted to the ground support column 3. The connection sleeve 42 facilitates the connection between the primary energy-absorbing rod 4 and the ground support column 3.

[0030] The working principle and usage process of this utility model are as follows: First, the deep-buried column 2 and the solid protective section 21 are buried in the ground. The deep-buried column 2 is completely buried in the ground, and the top of the solid protective section 21 protrudes above the ground. The deep-buried column 2 is wrapped and protected by compacting the surrounding soil or pouring concrete to increase its bending strength. Then, the connecting rod 32 is threaded into the inner wall of the bolt hole 22 until the bottom end of the sealing ring 34 is tightly fitted with the top of the solid protective section 21. Then, the connecting sleeve 42 is fitted onto the outer wall of the ground support column 3, and the connecting sleeve 42 and the ground support column 3 are fixed with bolts. Then, the corrugated guardrail body 1 is lifted and aligned with the connecting plate 41, and the mounting plate 11 and the connecting plate 41 are fixed with bolts. When the guardrail is hit by a vehicle, the corrugated guardrail body 1 and the mounting plate 11 are subjected to impact force, which then acts on the primary energy-absorbing rod 4, and then on the ground support column 3. The solid reinforcement section 31, connecting rod 32, buried column 2, and solid protective section 21 apply force. The ground support column 3 and the primary energy-absorbing rod 4 are the weakest points in terms of bending strength and deform first, absorbing the energy of the vehicle impact. When the impact force is large, the ground support column 3 further transmits the force to the connecting rod 32. With the reinforcement of the connecting rod 32 by the solid protective section 21 and the reinforcement of the connection between the ground support column 3 and the connecting rod 32 by the solid reinforcement section 31, the bending strength of both ends of the connecting rod 32 is greater than that of the hollow energy-absorbing tube 33 corresponding to the connecting rod 32. The part of the connecting rod 32 corresponding to the hollow energy-absorbing tube 33 will deform before the part of the connecting rod 32 inserted into the solid protective section 21 and the solid protective section 21. At this time, when the staff dismantles the guardrail, they only need to remove the connecting rod 32 from the solid protective section 21 and replace the upper structure.
