Description

Technical Field

[0001] This utility model relates to the field of highway guardrail technology, specifically to a corrugated guardrail. Background Technology

[0002] In the field of road traffic, guardrails, as key facilities for ensuring driving safety, play a vital role in reducing personal injury and property damage caused by traffic accidents. Early road guardrails mostly used rigid structures, such as concrete guardrails. While these guardrails possessed strong impact resistance, their lack of cushioning and energy absorption characteristics meant they were prone to violent rebound upon vehicle collision, leading to secondary accidents; moreover, the enormous impact force generated during a collision could cause serious injury to occupants. With the continuous increase in traffic volume and vehicle speed, the drawbacks of traditional rigid guardrails have become increasingly apparent, making them unable to meet the demands of modern traffic safety.

[0003] Against this backdrop, corrugated guardrails emerged. They consist of corrugated steel guardrail panels spliced ​​together and supported by posts to form a continuous structure. The deformation of the posts and beams absorbs collision energy and forces out-of-control vehicles to change direction and return to normal driving. Existing corrugated guardrails are generally installed on the soil along the edge of a road, with the posts inserted into the soil for fixation, and the soil covering the posts providing stable support. However, in some narrow mountain roads, to maximize the road area, the soil strip left on the edge of the road is narrow. If the original fixing method is still used, the soil near the edge of the corrugated guardrail posts is thin, limiting the lateral support force provided to the posts. Therefore, in the event of a car accident, the corrugated guardrail cannot provide sufficient lateral restraint for the vehicle, thus failing to effectively protect it and increasing the risk of the vehicle falling off the cliff.

[0004] In conclusion, there is an urgent need for a wave-shaped guardrail to solve, or at least partially solve, the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a corrugated guardrail, which aims to solve the problem that existing guardrails provide insufficient lateral support when the roadside is narrow, making them unable to effectively block vehicles. The specific technical solution is as follows:

[0006] A corrugated guardrail includes posts, corrugated guardrail panels, and diagonal pull-out members. The posts include a bottom post for insertion into the soil and a top post arranged along the height direction for installing the corrugated guardrail panels. The top post is fixedly connected to the top of the bottom post. The corrugated guardrail panels are fixedly connected to the upper part of the top post. The diagonal pull-out members include a fixing section for diagonally inserting into the soil and a connecting section for fixedly connecting to the middle of the post. The pull-out members and the corrugated guardrail panels are located on the same side of the post.

[0007] Furthermore, the column also includes a support plate for abutting against the soil, the support plate being welded and fixedly connected to the bottom of the top column; the connecting section of the inclined pull-out member is fixedly connected to the top column through the support plate.

[0008] Furthermore, the bottom of the base column is designed to be conical.

[0009] Furthermore, the column also includes a first helical blade, which is arranged around the base column and is fixedly connected to the outer wall of the base column.

[0010] Furthermore, the column also includes fasteners, and the top column and bottom column are detachably connected by fasteners.

[0011] Furthermore, the column also includes reinforcing ribs, with the first end of the reinforcing ribs fixedly connected to the supporting plate and the second end of the reinforcing ribs fixedly connected to the top column.

[0012] Furthermore, the reinforcing ribs are arranged along the width direction of the corrugated panel, and multiple reinforcing ribs are arranged at intervals along the circumference of the top column.

[0013] Furthermore, a second helical blade is provided on the fixed section of the inclined pull-out member. The second helical blade is arranged around the fixed section of the pull-out member and is fixedly connected to the fixed section of the inclined pull-out member.

[0014] Furthermore, the corrugated guardrail also includes a buffer component, which is arranged between the corrugated guardrail panel and the post. The first end of the buffer component is fixedly connected to the corrugated guardrail panel, and the second end of the buffer component is fixedly connected to the top post.

[0015] The application of the technical solution of this utility model has the following beneficial effects:

[0016] With the above structure, when a vehicle hits the corrugated guardrail, the vehicle applies a lateral force to the post and the corrugated guardrail towards the cliff side, while the inclined pull-out member provides a lateral force away from the cliff side for the post and the corrugated guardrail, enhancing the post and the corrugated guardrail's ability to resist lateral impact and preventing the vehicle from completely knocking down the corrugated guardrail and post, thus preventing a fall off the cliff.

[0025] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Example:

[0028] See Figures 1-5 This embodiment provides a corrugated guardrail, including a post 1, a corrugated guardrail panel 2, and an inclined pull-out member 3. The post 1 includes a bottom post 12 for inserting into the soil and a top post 11 arranged along the height direction for installing the corrugated guardrail panel 2. The top post 11 is fixedly connected to the top of the bottom post 12. The corrugated guardrail panel 2 is fixedly connected to the upper part of the top post 11. The inclined pull-out member 3 includes a fixing section 31 for obliquely inserting into the soil and a connecting section 32 for fixedly connecting to the middle of the post 1. The pull-out member and the corrugated guardrail panel 2 are located on the same side of the post 1.

[0029] It should be noted that during the installation of this device, the base post 12 of the column 1 is first inserted into the soil on the side of the road adjacent to the cliff, so that the soil wraps around and fixes the base post 12. Then, the inclined pull-out resisting member 3 is installed. The fixing section 31 of the inclined pull-out resisting member 3 is inserted into the soil along the inclined direction for fixation, and the connecting section 32 of the inclined pull-out resisting member 3 is fixedly connected to the middle of the column 1. Specifically, the connecting section 32 can be fixedly connected to the bottom of the top post 11, or it can be fixedly connected to the top of the base post 12. It should be noted that the inclined pull-out resisting member 3 needs to be set on the side of the column 1 closest to the road. After the column 1 and the inclined pull-out resisting member 3 are installed, the corrugated guardrail 2 is installed on the top of the top post 11, also on the side of the top post 11 closest to the road.

[0030] As can be seen, through the above structural design, when a vehicle impacts the corrugated guardrail 2, the vehicle applies a lateral force to the pillar 1 and the corrugated guardrail 2 towards the cliff side. The oblique pull-out member 3 provides a lateral force away from the cliff side to the pillar 1 and the corrugated guardrail 2, enhancing their resistance to lateral impact and preventing the vehicle from completely knocking down the guardrail and pillar 1, thus preventing a fall off the cliff. It is worth noting that the oblique pull-out member 3's role here is to improve the pillar 1 and the corrugated guardrail's resistance to lateral forces, but this does not mean that the pillar 1 and the corrugated guardrail will not deform at all during the impact. If they did not deform at all, the vehicle would not receive adequate cushioning, preventing a fall off the cliff but also causing severe damage. Therefore, the purpose of the oblique pull-out member 3 is to ensure that the pillar 1 deforms to a certain extent towards the cliff side during the impact, providing cushioning for the vehicle without causing the pillar 1 to completely detach from the soil. The magnitude of the lateral force provided by the inclined pull-out member 3 to the column 1 is controlled by controlling the length of the fixed section 31 in the inclined pull-out member 3. The longer the fixed section 31 is, the greater the angle of inclination towards the road side, and the greater the lateral force provided. The shorter the fixed section 31 is, the smaller the angle of inclination towards the road side, and the smaller the lateral force provided. An appropriate length of inclined pull-out member 3 is selected for application as needed.

[0031] In a preferred embodiment, the column 1 further includes a support plate 13 for abutting against the soil, the support plate 13 being welded and fixedly connected to the bottom of the top column 11; the connecting section 32 of the inclined pull-out member 3 is fixedly connected to the top column 11 through the support plate 13. Specifically, the support plate 13 is provided with a through hole, the upper end face of which is set as an inclined surface. During installation, the fixing section 31 of the inclined pull-out member 3 passes through the through hole on the support plate 13 from top to bottom and is inserted into the soil for fixing, while the connecting section 32 abuts against and is fixed to the inclined surface on the support plate 13.

[0032] It can be seen that by setting up the support plate 13, on the one hand, the support plate 13 can effectively connect the inclined pull-out member 3 to the column 1, so that when the vehicle hits the corrugated guardrail 2, the inclined pull-out member 3 can provide lateral force for the column 1 and the corrugated guardrail 2. On the other hand, the support plate 13 is supported on the soil of the ground, which improves the stability of the column 1.

[0033] As a preferred embodiment, the bottom of the base post 12 is configured as a cone shape.

[0034] It is known that by setting it into a cone shape, the pressure on the soil can be effectively increased when the bottom column 12 is inserted into the soil, making it easier to insert the bottom column 12 into the soil.

[0035] In a preferred embodiment, the column 1 further includes a first helical blade 14, which is arranged around the base column 12 and is fixedly connected to the outer wall of the base column 12.

[0036] It is understood that by setting the first helical blade 14 on the outside of the base column 12, when installing the base column 12, the base column 12 is rotated while downward pressure is applied to the base column 12. Because the first helical blade 14 can generate a downward component force during rotation, the base column 12 can be inserted into the soil more easily. In addition, the setting of the first helical blade 14 can strengthen the bond between the base column 12 and the ground soil, preventing the base column 12 from being pulled out during impact.

[0037] In a preferred embodiment, the column 1 further includes a fastener 15, and the top column 11 and the bottom column 12 are detachably connected by the fastener 15. Specifically, a flange is welded to the top of the bottom column 12, and a first connecting hole is provided on the flange. A second connecting hole is provided on the support plate 13 welded to the bottom of the top column 11. The fastener 15 passes through the first connecting hole and the second connecting hole on the flange in sequence for locking connection. In this embodiment, the first connecting hole is a through hole, the second connecting hole is a threaded hole, and the fastener 15 is a screw. In some other embodiments of this application, both the first and second connecting holes can be through holes, and the fastener 15 can be a bolt, which passes through the first and second connecting holes in sequence for fastening connection.

[0038] It is understood that with this setup, during installation, the base column 12 is connected to the installation equipment via the flange. The installation equipment applies downward pressure and horizontal torque to the base column 12, causing it to rotate while pressing it downward, thus facilitating the insertion of the base column 12 into the soil. After insertion, it can be easily connected to the top column 11 via the fastener 15.

[0039] In a preferred embodiment, the column 1 further includes reinforcing ribs 16. The first end of the reinforcing rib 16 is fixedly connected to the upper surface of the supporting plate 13 by welding, and the second end of the reinforcing rib 16 is fixedly connected to the side wall of the top column 11 by welding. The reinforcing ribs 16 are arranged along the width direction of the corrugated panel 2, and multiple reinforcing ribs 16 are arranged at intervals along the circumference of the top column 11.

[0040] It can be seen that by setting the reinforcing rib 16, the connection strength between the supporting plate 13 and the top column 11 is improved, and the overall rigidity of the column 1 is improved.

[0041] In a preferred embodiment, a second helical blade 33 is provided on the fixing section 31 of the inclined pull-out resisting member 3. The second helical blade 33 is arranged around the fixing section 31 of the pull-out resisting member and is fixedly connected to the fixing section 31 of the inclined pull-out resisting member 3. Specifically, the lower end of the fixing section 31 is tapered to facilitate the insertion of the inclined pull-out resisting member 3 into the soil. The connecting section 32 is provided with an abutment cap, and the upper part of the abutment cap is provided with a hexagonal rotating part. The inclined pull-out resisting member 3 can be easily rotated by connecting an external power tool to the hexagonal rotating part, which facilitates installation. After the inclined pull-out resisting member 3 is installed, the lower surface of the abutment cap abuts against the inclined surface of the support plate 13. Two sets of inclined pull-out resisting members 3 are provided, and the two sets of inclined pull-out resisting members 3 are spaced apart along the length direction of the corrugated guardrail 2. Both sets of inclined pull-out resisting members 3 are connected to the support plate 13.

[0042] It is understood that, through the setting of the second helical blade 33, when installing the inclined pull-out member 3, a positive pressure is applied to the inclined pull-out member 3 while the inclined pull-out member 3 is rotated, so that the inclined pull-out member 3 can be inserted into the soil more easily for installation; in addition, the second helical blade 33 enhances the connection strength between the inclined pull-out member 3 and the soil, so that the inclined pull-out member 3 can provide sufficient lateral force for the column 1.

[0043] In a preferred embodiment, the corrugated guardrail also includes a buffer 4, which is arranged between the corrugated guardrail 2 and the post 1. The first end of the buffer 4 is fixedly connected to the corrugated guardrail 2, and the second end of the buffer 4 is fixedly connected to the top post 11.

[0044] It is known that the buffer 4 is made of plastic iron sheet wound into a ring. One side of the ring is detachably connected to the corrugated guardrail 2, and the other side is detachably connected to the top post 11. Through the installation of the buffer 4, when a vehicle impacts the corrugated guardrail 2, the buffer 4 undergoes plastic deformation, absorbing the energy of the impact and reducing damage to the vehicle, as well as reducing damage to the post 1.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
