Description

Technical Field

[0001] This application relates to the field of road construction facilities technology, and in particular to a barrier block and guardrail. Background Technology

[0002] In the field of highway guardrails, anti-blocking blocks are typically used to fix the guardrail beams to the posts. However, on some older roads, after repaving, the height of the guardrail beams may be insufficient, reducing the safety of the guardrails. Because the guardrail beam height does not meet requirements, the entire guardrail needs to be removed and replaced, resulting in a waste of resources. Furthermore, since the ends of the posts are buried underground, removal or installation is difficult and time-consuming. Utility Model Content

[0003] The anti-blocking block and guardrail provided in this application can adjust the height of the protective beam and the road surface, thereby achieving non-destructive adjustment of the guardrail height.

[0004] This application provides an anti-blocking block for connecting the posts and protective beams of a guardrail. The anti-blocking block includes two side plates arranged opposite to each other, a cover plate fixedly connected to the top of the two side plates, a back plate fixedly connected to the two side plates and the cover plate, and a front plate fixedly connected to the two side plates. The front plate and the back plate are arranged opposite to each other. The two side plates, the back plate and the front plate form a sleeve portion. The sleeve portion is sleeved on the outer wall of the post and detachably connected to the post.

[0005] Both side plates are provided with multiple first mounting holes, which are spaced apart along a direction perpendicular to the road surface.

[0006] In the above embodiment, the sleeve portion of the anti-blocking block is fitted onto the outer wall of the post, ensuring a reliable connection between the anti-blocking block and the post. By aligning the first mounting hole of the anti-blocking block with different second mounting holes on the post, the installation height of the anti-blocking block can be adjusted, thereby adjusting the height of the protective beam above the ground. This allows the guardrail to adapt to changes in the road surface after maintenance and paving. It eliminates the construction and labor costs associated with removing and replacing the original guardrail.

[0007] In one embodiment, the protective beam of the guardrail is a corrugated plate, the corrugated plate includes wave crests and troughs spaced apart along the extension direction of the post, and the two side plates each include a protrusion that matches the shape of the raised area on the back side of the corrugated plate.

[0008] In one embodiment, the side panel is L-shaped and includes a support portion and a mounting portion connected to each other, with the front panel connected to the mounting portion.

[0009] In one embodiment, the anti-blocking block further includes two connecting plates, each of which is connected to a support portion of one of the side plates, and the connecting plates are used to connect the protective beam.

[0010] In one embodiment, the connecting plate is parallel to the front plate, and the front plate and the connecting plate do not overlap in a direction perpendicular to the front plate.

[0011] In one embodiment, the connecting plate is provided with a plurality of third mounting holes, which are spaced apart; the protective beam of the guardrail is provided with a plurality of fourth mounting holes, and the distance between two adjacent third mounting holes is equal to the distance between two adjacent fourth mounting holes.

[0012] In one embodiment, the first mounting hole is located in the sleeve portion.

[0013] In one embodiment, the sleeve portion is located entirely within the cover plate in its vertical projection onto the cover plate.

[0014] On the other hand, embodiments of this application also provide a guardrail, which includes a post, a protective beam and the aforementioned anti-blocking block, wherein the anti-blocking block is installed at the end of the post away from the road surface and the protective beam is installed on the anti-blocking block.

[0015] In one embodiment, the protective beam is a three-wave protective beam, comprising three wave crests and two wave troughs, wherein the two wave troughs are respectively connected to the anti-blocking block. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of the application is provided in conjunction with the accompanying drawings and embodiments.

[0022] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more” unless the context clearly indicates otherwise.

[0023] References to “an embodiment” or “a specific embodiment” as used in this specification mean that one or more embodiments of this application include a particular feature, structure, or characteristic described in connection with that embodiment. The terms “comprising,” “including,” “having,” and variations thereof mean “including, but not limited to,” unless otherwise specifically emphasized.

[0024] In related technologies, guardrails are typically installed on both sides of roads to guide vehicles within designated lanes and prevent them from deviating from the road due to loss of control or driver negligence. Guardrails consist of posts, protective beams, and anti-collision blocks. One end of the post is buried underground, and the other end is connected to the protective beam via anti-collision blocks. The anti-collision blocks, acting as load-bearing components between the protective beam and the post, serve as both a connecting structure and an energy-absorbing mechanism. In traffic accidents, when the protective beam is impacted, it transfers the impact energy to the anti-collision blocks. The anti-collision blocks absorb some of the impact energy through deformation, thus mitigating the severity of injuries or fatalities. The installation height and position of the anti-collision blocks need to be determined based on the specific crashworthiness rating to ensure the effective protection of the guardrail. Corrugated beam guardrails are suitable for various road grades, including highways, Class I roads, and Class II roads. Different grades of corrugated beam guardrails are suitable for different road conditions and speed requirements. For three-wave corrugated beam guardrails (e.g., Class A or Class SB), the center height of the crossbeam, measured from the road surface or curb to the center of the three-wave beam, should be 697 mm. For some older roads, repaving can result in insufficient guardrail height, reducing their safety. Removing the existing guardrails and replacing them all with new, compliant ones would be a significant waste of resources and present considerable construction difficulties.

[0025] To address the aforementioned issues, this application provides a barrier block and a guardrail that can adjust the height of the protective beam relative to the road surface, thereby achieving non-destructive adjustment of the guardrail height.

[0026] Figure 1 This is a schematic diagram of the structure of the anti-blocking block provided in an embodiment of this application. Figure 2 A side view of a blocking block provided in one embodiment of this application. (In conjunction with...) Figure 1 and Figure 2 This application provides an anti-blocking block for connecting a guardrail post 200 and a protective beam 300. The anti-blocking block includes two side plates 1 arranged opposite each other, a cover plate 2 fixedly connected to the top of the two side plates 1, a back plate 3 fixedly connected to the two side plates 1 and the cover plate 2, and a front plate 4 fixedly connected to the two side plates 1. The front plate and the back plate 3 are arranged opposite each other. The front plate 4 and the cover plate 2 are spaced apart by a preset distance in a direction perpendicular to the cover plate 2. The two side plates 1, the back plate 3, and the front plate 4 enclose a sleeve portion 101 adapted to the post 200. The sleeve portion 101 is sleeved on the outer wall of the post 200 and detachably connected to the post 200. Each of the two side plates 1 is provided with a plurality of first mounting holes 11, which are spaced apart in a direction perpendicular to the road surface 0. The post 200 is provided with second mounting holes 201 spaced apart in a direction perpendicular to the road surface 0. The first mounting holes 11 are installed in correspondence with different second mounting holes 201 to adjust the installation height of the anti-blocking block.

[0027] In the above embodiment, the sleeve portion 101 of the anti-blocking block is fitted onto the outer wall of the column 200, making the connection between the anti-blocking block and the column 200 more reliable. By connecting the first mounting hole 11 of the anti-blocking block with different second mounting holes 201 of the column 200, the installation height of the anti-blocking block can be adjusted, thereby adjusting the height of the protective beam 300 above the ground. This allows the guardrail to adapt to changes in the road surface after maintenance and paving. It eliminates the construction and labor costs of removing and replacing the original guardrail.

[0028] In one embodiment, the first mounting hole 11 may be located throughout the side plate 1 or only in the sleeve portion 101 area of ​​the side plate 1.

[0029] The anti-blocking block type, where the first mounting hole 11 is located only in the sleeve portion 101, is suitable for the construction and renovation of existing guardrails. During guardrail renovation, the anti-blocking block provided in this embodiment can replace the original anti-blocking block. The anti-blocking block of this application has a sleeve portion 101, which is longer than the original anti-blocking block. By connecting the first mounting hole 11 located in the sleeve portion 101 with the second mounting hole 201 of the guardrail post 200, the height of the original guardrail can be increased.

[0030] The type of anti-blocking block with the first mounting hole 11 located on the entire side plate 1 is suitable for newly laid guardrails, and the height adjustment range of the anti-blocking block is wider.

[0031] In one embodiment, the vertical projection of the sleeve portion 101 onto the cover plate 2 is entirely within the cover plate 2. The side plate 1, front plate 4, back plate 3, and cover plate 2 can be an integral structure, allowing the anti-blocking block 100 to be installed as a whole, improving installation efficiency. The area of ​​the cover plate 2 is relatively larger than the cross-sectional area of ​​the sleeve portion 101, and it is an integral structure with the side plate 1 and back plate 3, which reduces the possibility of rainwater entering the sleeve portion 101, thereby reducing the occurrence of rust on the column.

[0032] In one embodiment, the guardrail's protective beam 300 is a corrugated plate, which includes wave crests n and wave troughs m spaced apart along the extension direction of the post 200. The two side plates 1 each include a protrusion 12 adapted to the shape of the raised area on the back side of the corrugated plate. In this embodiment, the protective beam 300 can specifically be a three-wave protective beam, having two wave troughs m and three wave crests n. The two wave troughs m protrude towards the side where the anti-blocking block is located, and the three wave crests n protrude towards the side away from the anti-blocking block. The protrusion 12 is connected to the outer wall of the upper wave trough m. The protrusion 12 has an inclined edge that fits against the outer wall of the upper wave trough m, thereby improving the support strength of the protective beam 300.

[0033] In one embodiment, the vertical projection of the front panel 4 onto the back panel 3 is entirely within the back panel 3, and the smaller area of ​​the front panel 4 compared to the back panel 3 saves material.

[0034] In one embodiment, the side panel 1 may be L-shaped, including a support portion 13 and a mounting portion 14 connected to each other. The support portion 13 extends away from the column 200, and the mounting portion 14 extends towards the road surface 0. The front panel 4 is connected to the mounting portion 14, and its protrusion is located on the support portion 13.

[0035] The anti-blocking block also includes two connecting plates 5, each connecting plate 5 being connected to a support portion 13 of a side plate 1. The connecting plates 5 are used to connect the protective beams of the guardrail. Specifically, the connecting plate 5 is connected to two trough portions m.

[0036] In one embodiment, the connecting plate 5 is provided with a plurality of third mounting holes 51, which are spaced apart. Correspondingly, each trough of the protective beam 300 is provided with a fourth mounting hole 52. The distance 'a' between two adjacent third mounting holes 51 is equal to the distance 'b' (the distance between two troughs) between two adjacent fourth mounting holes 52. When installing the three-wave protective beam, the fourth mounting holes 52 of the protective beam 300 are aligned one-to-one with the third mounting holes 51 of the anti-blocking block, and then screws are inserted for fixing.

[0037] In one embodiment, the connecting plate 5, the front plate 4, and the rear plate are parallel to each other, and the front plate 4 and the connecting plate 5 do not overlap in a direction perpendicular to the front plate 4. Specifically, the connecting plate 5 extends outward from the side plate 1, resulting in a larger overlap area between the anti-blocking block and the protective beam 300, thereby increasing the support strength of the protective beam 300.

[0038] Figure 3 A schematic diagram of the structure of a guardrail provided in one embodiment of this application is shown below. Figure 3 As shown, on the other hand, embodiments of this application also provide a guardrail, which includes a post 200, a protective beam 300, and a blocking block as described in any of the above embodiments. The blocking block is installed at the end of the post 200 away from the road surface 0, and the protective beam 300 is installed on the blocking block. The road surface 0 is provided with a curb stone 00. After the guardrail is installed, the distance from the top surface of the curb stone 00 to the center of the protective beam 300 is 697mm. The blocking block is provided with multiple sets of first mounting holes 11, which can meet the requirement that if the guardrail height is insufficient after the road surface 0 is resurfaced in the future, the relative position of the blocking block and the post 200 can be adjusted so that the first mounting holes 11 correspond to the second mounting holes 201 at different positions, thereby achieving a lossless increase in the height of the protective beam 300.

[0039] In one specific embodiment, the cross-section of the column 200 parallel to the road surface 0 is square or circular. The sleeve portion 101 of the anti-blocking block has a square cross-section, which can be adapted to the column 200, thereby improving the reliability of the connection between the anti-blocking block and the column 200.

[0040] When the cross-section of the column 200 is circular, the diameter of the circle is slightly smaller than the side length of the square cross-section of the sleeve portion 101, and the square sleeve portion 101 can be fitted onto the outside of the column 200.

[0041] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
