Description

Technical Field

[0001] The present invention relates to the field of highway protection, and in particular to an outward-extending anti-collision guardrail installation structure. Background Art

[0002] With the increase in highway mileage and the prevalence of cars in China, traffic accidents occurring at guardrail ends and in the exit triangle are increasing. According to the "Design Specifications for Highway Traffic Safety Facilities" (JTGD81-2017), guardrail ends on highways facing traffic should: extend beyond the width of the earth shoulder; when located at the intersection of cut-fill and fill, extend and be buried within the earth, where the cut does not pose an obstruction; if extension is not possible, a collision-resistant end should be installed, or a head should be placed in front of the guardrail end. This helps mitigate impact and reduce injuries to colliding vehicles and occupants.

[0003] The current use of planting soil and backfill within the central medians of domestic expressways and first-class highways has hindered the full bearing capacity of guardrail posts. This is especially true when the roadside guardrail posts are extended outward, often failing to meet the required earth shoulder protection layer width, resulting in the guardrail's inability to fully utilize its protective function. Furthermore, when the guardrail is extended outward, there is no effective solution for encountering drainage ditches. Typically, a pile is driven outside the ditch and then connected using corrugated plates, with little regard for the regulatory requirements for the gradient and protection level. Another approach is to rivet flange posts onto the ditch cover, which takes the gradient into account but cannot guarantee guardrail strength. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned problem that the lateral spacing between the anti-collision surface of the guardrail beam and the anchoring column is insufficient, which makes it impossible to anchor across the ditch and the ground and maintain the overall anti-collision performance of the guardrail. It provides an outward-extended anti-collision guardrail installation structure, and the anchoring column can be anchored across the ditch and the ground and maintain the overall anti-collision performance of the guardrail.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A flared anti-collision guardrail mounting structure, which is arranged at the end of a guardrail and extends toward the outside of the road relative to the main body of the guardrail. The flared anti-collision guardrail mounting structure includes a group of supporting anchoring devices and an flared guardrail crossbeam. A group of the supporting anchoring devices is connected to the flared guardrail crossbeam. The flared guardrail crossbeam extends toward the outside of the road relative to the guardrail beam of the main body of the guardrail.

[0007] As an improvement of the above technical solution, the support anchoring device includes a fixed column, a connecting member and a supporting member. The fixed column is fixed on the ground, one end of the connecting member is connected to the end of the fixed column, the other end of the connecting member is connected to the supporting member, and the supporting member is connected to the outward guardrail beam.

[0008] As an improvement of the above technical solution, the support member includes a first bracket and a second bracket, one end of the first bracket and the second bracket are connected to the end of the connecting member away from the fixed column, and the other end of the first bracket and the second bracket are connected to the outward guardrail beam.

[0009] As an improvement of the above technical solution, an angle β is formed between the first bracket, the second bracket and the outward guardrail beam.

[0010] As an improvement of the above technical solution, the angle is 20 degrees to 45 degrees.

[0011] As an improvement of the above technical solution, the first bracket includes a first support arm and a first support column, the first support column is rotatably connected to the connecting member, one end of the first support arm is connected to the outward-extending beam, and the other end of the first support arm is connected to the first support column; the second bracket includes a second support arm and a second support column, the second support column is rotatably connected to the connecting member, the two ends of the second support arm are connected to the outward-extending beam, and the other two ends of the second support arm are connected to the second support column.

[0012] As an improvement of the above technical solution, a first mounting hole and a second mounting hole are provided on the connecting member, and the first support column and the second support column are rotatably connected to the first mounting hole and the second mounting hole respectively.

[0013] As an improvement of the above technical solution, the outward guardrail beam includes a transition beam and a new beam, one end of the transition beam overlaps with the guardrail body, and the other end of the transition beam overlaps with the new beam, and the supporting anchoring device is connected to the new beam and / or the transition beam.

[0014] As an improvement of the above technical solution, an end of the transition beam facing outward is provided with an end cap, and the cross section of the new beam is four-wave-shaped.

[0015] As an improvement to the above technical solution, a group of the supporting anchoring devices are arranged at intervals.

[0016] Compared with the prior art, the beneficial effects of this application are:

[0017] An outward-extending anti-collision guardrail installation structure of the present invention includes a group of support anchoring devices and outward-extending guardrail beams, wherein the fixed columns in the support anchoring devices are fixed on the ground, the connecting parts and the supporting parts can increase the span, and the guardrail panels can be hung, so that the guardrail columns can be installed across the junction of fill and excavation and the drainage ditch when extended, while ensuring the protection level.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] like Figures 1 to 12 As shown, the present invention provides an outward-extending anti-collision guardrail installation structure, which is arranged at the end of the guardrail and extends toward the outside of the road relative to the guardrail body 3.

[0036] This application is generally used for the intersection of fill and excavation on sections of expressways and first-class highways facing traffic flow, especially on sections facing traffic flow with drainage ditches.

[0037] The outward-extending anti-collision guardrail installation structure includes a group of supporting anchoring devices 1 and an outward-extending guardrail crossbeam 2. A group of the supporting anchoring devices 1 is connected to the outward-extending guardrail crossbeam 2, and the outward-extending guardrail crossbeam 2 extends toward the outside of the road relative to the guardrail main body 3.

[0038] The support anchoring device 1 is used to install and support the outward-extending guardrail, which can improve the protective effect of the end of the guardrail.

[0039] The outward-extending guardrail beam 2 can mitigate impact and reduce damage to the colliding vehicle and the people in the vehicle, thereby preventing the vehicle from drilling out and falling from the gap below the outward-extending guardrail beam 2. A set of the supporting anchor devices 1 is arranged on the side of the outward-extending guardrail beam 2 away from the road surface.

[0040] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 A group of the support and anchoring devices 1 are arranged at intervals, and the support and anchoring devices 1 include a fixing column 11, a connecting member 12 and a supporting member 13. Specifically, the fixing columns 11 are arranged at intervals of 4 meters.

[0041] The fixing post 11 is fixed on the ground on the side of the outward-extending guardrail beam 2 away from the road surface, and because the connecting member 12 and the supporting member 13 have a certain length, when the outward-extending guardrail beam 2 is installed on the supporting member 13, the connecting member 12 and the supporting member 13 can cross the cut-fill junction and the drainage ditch, so that there is a certain distance between the fixing post 11 and the outward-extending guardrail beam 2; furthermore, if the outward-extending guardrail beam 2 or the guardrail body 3 is set at the ground cut-fill junction or drainage ditch, the fixing post 11 can avoid the ground cut-fill area or drainage ditch below the outward-extending guardrail beam 2 or the guardrail body 3, and take root and fix in the ground cut-fill area or drainage ditch, thereby reducing the difficulty of installing the outward-extending guardrail beam 2 at the cut-fill junction or drainage ditch, and at the same time improving the fixing effect and protection level of the outward-extending guardrail beam 2. The protection level of this application can reach Class A.

[0042] Specifically, the fixing column 11 can be buried or cast in the ground. The fixing column 11 can be a circular tube column or a square tube column; it can be made of metal or cast concrete, as long as it can ensure strength. In this embodiment, the fixing column 11 is preferably a square tube column. During installation, the fixing column 11 can be driven into the ground, eliminating the need for excavation and pouring a concrete foundation, making it easy to root and fix. Specifically, the piling depth of the fixing column 11 is 12 meters.

[0043] See also Figures 5 to 7 One end of the connecting member 12 is connected to the end of the fixing column 11 located on the ground. Specifically, the connecting member 12 can be welded to the fixing column 11, integrally formed, or detachably connected.

[0044] The other end of the connecting member 12 is connected to the support member 13. Similarly, the connecting member 12 can be welded, integrally formed, or detachably connected to the support member 13. The support member 13 is connected to the outward-extending guardrail beam 2. Similarly, the support member 13 can be welded, detachably connected, or connected using any connection method known in the art.

[0045] See also Figure 1 and Figure 4 It should be noted that in the embodiments of the present application, the lengths of the connectors 12 in each set of the support anchoring devices 1 can vary, as long as the connectors 12 and the support members 13 can span the cut-fill interface, the drainage ditch, and the gradual slope of the outward-facing guardrail beam 2. In other words, as long as the fixing posts 11 are located at the cut-fill interface and outside the drainage ditch, they will suffice.

[0046] See also Figures 1 to 7 In some embodiments of the present application, the support member 13 includes a first bracket 131 and a second bracket 132. One end of each of the first bracket 131 and the second bracket 132 is connected to the end of the connector 12 away from the fixing post 11, and the other ends of the first bracket 131 and the second bracket 132 are connected to the outward-extending guardrail beam 2. The first bracket 131 and the second bracket 132 can provide support for the outward-extending guardrail beam 2.

[0047] See also Figures 5 to 7In some embodiments of the present application, the first bracket 131 includes a first support arm 131a and a first support column 131b. Specifically, the first support column 131b is rotatably connected to the connecting member 12, one end of the first support arm 131a is connected to the outward-extending guardrail beam 2, and the other end of the first support arm 131a is connected to the first support column 131b; the second bracket 132 includes a second support arm 132a and a second support column 132b, the second support column 132b is rotatably connected to the connecting member 12, one end of the second support arm 132a is connected to the outward-extending guardrail beam 2, and the other end of the second support arm 132a is connected to the second support column 132b.

[0048] Specifically, the connector 12 is provided with a first mounting hole 121 and a second mounting hole 122. The first support column 131b and the second support column 132b are rotatably connected to the first mounting hole 121 and the second mounting hole 122, respectively. In the event of an impact, the first support column 131b and the second support column 132b can rotate to relieve force and provide cushioning. Specifically, the first support column 131b and the second support column 132b are circular tubes.

[0049] In some embodiments of the present application, to provide better support for the outward-facing guardrail beam 2, the first bracket 131 and the second bracket 132 form an angle β with the outward-facing guardrail beam 2. Specifically, the first support arm 131a forms an angle β with the outward-facing guardrail beam 2. Similarly, the second support arm 132a forms an angle β with the outward-facing guardrail beam 2.

[0050] More specifically, the angle β is 20 degrees to 45 degrees. In some preferred embodiments of the present invention, the angle β is 30 degrees.

[0051] After multiple simulated collision tests, this application has found that the best effect is achieved when the angle β is around 20 degrees to 45 degrees. When it is greater than 45 degrees, the first support arm 131a and the second support arm 132a will be detrimental to the guidance of the colliding vehicle; when it is less than 20 degrees, it is necessary to increase the length of the first support arm 131a and the second support arm 132a, so that the fixed column 11 is away from the outward guardrail beam 2, which will increase the cost; otherwise, the first support column 131b and the second support column 132b will easily obstruct the wheels.

[0052] In other embodiments of the present application, the first support column 131b and the second support column 132b can be fixedly connected to the connector 12 or detachably connected, and the first support arm 131a can be rotatably connected to the first support column 131b, and the second support arm 132a can be rotatably connected to the second support column 132b, thereby achieving the same effect. For example, the first support arm 131a is hinged to the first support column 131b, and the second support arm 132a is hinged to the second support column 132b, and the angle between the first support arm 131a and the second support arm 132a can be between 20 degrees and 40 degrees.

[0053] See also Figure 1 、 Figure 3 and Figure 4 The outward-facing guardrail crossbeam 2 is the main body of the outward-facing anti-collision guardrail mounting structure, providing protection and guidance for vehicles. The outward-facing guardrail crossbeam 2 extends outward relative to the guardrail body 3, with a certain angle α between their extension directions. In some preferred embodiments of the present application, the angle α is 4.1 degrees.

[0054] See also Figure 1 、 Figure 3 、 Figure 4 、 Figures 8 to 12 The outward-extending guardrail beam 2 includes a transition beam 21 and a new type of beam 22. One end of the transition beam 21 overlaps the guardrail body 3, and the other end of the transition beam 21 overlaps the new type of beam 22. The support anchor device 1 is connected to the new type of beam 22 and / or the transition beam 21. Specifically, the first support arm 131a and the second support arm 132a can be connected to the transition beam 21 and / or the new type of beam 22 and / or the guardrail body by bolts. The transition beam 21 and the new type of beam 22 can be corrugated beam plates, channel steels, C-beams, square and rectangular tubes, special-shaped tubes, etc.

[0055] See also Figures 10 to 12 In some embodiments of the present invention, preferably, the cross section of the novel cross beam 22 is four-waveform, and the specification of the four-waveform beam plate is 600*52*3. Its width is about 100mm wider than that of the three-waveform beam plate 506*85*3 without increasing the material consumption, which can effectively prevent vehicles from passing through the bottom of the guardrail.

[0056] An end cap 4 is provided at an outward end of the transition beam 21 .

[0057] The present invention provides an outward-extending anti-collision guardrail installation structure, comprising a set of support anchoring devices 1 and an outward-extending guardrail beam 2, wherein the fixed column 11 in the support anchoring device 1 is fixed to the ground, and the connecting member 12 and the supporting member 13 can increase the span and hang the guardrail plate, so that the guardrail column can be installed across the fill-excavation junction and the drainage ditch when it is outward-extended, while ensuring the protection level. During installation, only piling is required, without the need for excavation or pouring of concrete foundations. The transition beam 21 can smoothly overlap with the guardrail body and / or the four-corrugated beam, which can reduce the situation where the connection cannot be made during on-site installation. The four-corrugated beam plate can increase the longitudinal protection width and effectively prevent vehicles from passing through the bottom of the guardrail. The first support column 131b and the second support column 132b are rotatably connected to the first mounting hole 121 and the second mounting hole 122 respectively; in the event of a collision, the first support column 131b and the second support column 132b can rotate to unload and buffer. The first support arm 131a and the second support arm 132a can also increase the span.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the same. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be included in the scope of the technical solutions of the present invention.
