Description

Technical Field

[0001] This utility model relates to the field of traffic facility technology, and more particularly to the field of road guardrail device technology, specifically to a modular plug-in traffic guardrail. Background Technology

[0002] Traffic barriers are devices used on roads to separate motor vehicle lanes from non-motor vehicle lanes, and to serve as a central divider for motor vehicles. They separate traffic flows and isolate areas for vehicles traveling in different directions and of different types. To a certain extent, they can regulate traffic and reduce traffic accidents, and are an indispensable component of traffic facilities.

[0003] Existing traffic barriers can be categorized by material into concrete barriers and metal barriers. Concrete barriers are generally used on urban center roads or suburban expressways. Due to their weight and difficulty in transportation and handling, concrete barriers are typically installed on roads with at least four lanes in both directions and large turning radii. They are generally not suitable for roads with small turning radii and low straightness. Metal barriers have a wider range of applications, suitable for smaller road separations and used in conjunction with concrete bases. Currently, the most common type of metal barrier uses a combination of connecting seats and grid-type guardrails. This modular installation offers high convenience, and the use of connecting seats in contact with the ground effectively avoids the high requirements for ground flatness found in concrete barriers. Their ease of installation, adaptability to road flatness, and high installation efficiency have led to their widespread use. However, interlocking metal guardrails also have significant drawbacks. Because they cannot be fixed to the ground, in the event of a traffic accident, the guardrails and connecting brackets are easily scattered and fragmented upon impact. The grid-type guardrails can easily become lodged in vehicles, further exacerbating the damage from the accident. To overcome the inconvenience of transporting and installing existing concrete guardrails, and the instability of metal guardrails, there is an urgent need for a multifunctional, high-performance traffic guardrail that integrates convenient transportation and installation with stable installation to replace existing traditional guardrails. Utility Model Content

[0004] To address the problems of existing concrete guardrails requiring hoisting machinery for transportation and installation, having requirements for road flatness and turning radius, resulting in inconvenient installation and low adaptability; and existing grid-type composite metal guardrails failing to be fixed to the ground, easily scattering debris during traffic accident collisions, causing damage to vehicles or bodies, and exhibiting poor stability and weak resistance to external forces, this application provides a modular plug-in traffic guardrail that can effectively form a fixed structure with the road surface and is adaptable to installation on different roads, demonstrating strong adaptability.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] The modular plug-in traffic barrier comprises multiple detachable and fixedly connected barrier units. Each barrier unit includes a first horizontal protective member arranged opposite to each other. Between two first horizontal protective members, there are at least multiple sets of connecting components located at both ends of the first horizontal protective members, and a first longitudinal beam that runs through two adjacent sets of connecting components and snaps together two adjacent barrier units. The connecting components are fixedly connected to the first longitudinal beam, the first horizontal protective member, and the ground respectively by fasteners.

[0007] Preferably, the connecting assembly includes a first crossbeam and a third crossbeam arranged sequentially from bottom to top. The two ends of the first crossbeam are fixedly connected to adapter plates for connecting with the first horizontal protective member. The adapter plates are provided with clearance holes at corresponding positions of the first horizontal protective member. The first crossbeam is also provided with through holes for installing fasteners at positions corresponding to the clearance holes.

[0008] Further preferably, the present invention also provides another structural combination of the connecting component. Specifically, the connecting component includes a first crossbeam, a second crossbeam, and a third crossbeam arranged sequentially from bottom to top. Each crossbeam includes a beam body, a snap-fit ​​groove provided on the beam body for accommodating and snapping the first longitudinal beam, and a side end face for matching the structure of the first horizontal protective component or guardrail cover. The side end face is provided with a connecting hole for installing fasteners or connectors.

[0009] Preferably, it further includes a second horizontal protective member, the two ends of which are provided with through grooves for receiving and engaging the first longitudinal beam, and the second horizontal protective member is fixedly connected to the first longitudinal beam and / or the first horizontal protective member by fasteners.

[0010] Preferably, the first longitudinal beam extends upward above the first horizontal protective member and is plugged into or fixedly connected to the third horizontal protective member.

[0011] Preferably, at least a plurality of second longitudinal beams are installed between the third horizontal protective member and the first horizontal protective member.

[0012] Preferably, at least a plurality of second longitudinal beams are installed between the third horizontal protective member and the second horizontal protective member.

[0013] To facilitate connection, two adjacent guardrail units are connected. Preferably, the cross-section of the first longitudinal beam is I-shaped.

[0014] To further reduce damage caused by external impacts, preferably, the guardrail also includes anti-collision structures fixedly connected to both ends of the guardrail.

[0015] Furthermore, preferably, the anti-collision structure includes a plurality of vertically mounted and rotatable anti-collision cylinders.

[0016] Beneficial effects:

[0017] 1. This utility model uses a snap-fit ​​longitudinal beam to connect two adjacent guardrail units, which can quickly complete the installation of the guardrail. At the same time, since the longitudinal beam is fixed to the ground with fasteners, it not only improves the stability between the guardrail and the ground, but also reduces the guardrail's requirements for ground flatness, allowing it to better fit the ground and solving the problem of installation stability.

[0018] 2. This utility model adopts a combined structure of frame structure and cover, which can not only ensure the strength requirements and have good resistance to external impact, but also have good integrity, so that the structure will not be scattered due to traffic accident impact, causing potential injury to cars and pedestrians.

[0019] 3. By installing the third longitudinal beam and the third horizontal protective component, the height of the guardrail can be increased and reinforced according to the requirements of the road where it is installed, thus meeting the needs of different roads for guardrails and effectively expanding the application scenarios of this utility model.

[0020] 4. This utility model adopts a multi-beam structure design, and the beams are connected to the longitudinal beams and the protective components used for covering the guardrail by fasteners. This allows for the design of guardrail structures of different sizes and shapes according to actual needs. Furthermore, the frame structure can improve installation efficiency while ensuring strength. During transportation, large structural components are not required, thus minimizing space occupation.

[0038] Example 1:

[0039] This embodiment provides a modular plug-in traffic barrier; the structure is shown in the attached instruction manual. Figures 1-7 As shown, the guardrail unit 100 is composed of multiple detachable and fixedly connected guardrail units 100. Each guardrail unit 100 includes a first horizontal guardrail member 1 arranged opposite to each other. Between two first horizontal guardrail members 1, there are at least multiple sets of connecting components located at both ends of the first horizontal guardrail member 1, and a first longitudinal beam 7 that runs through two adjacent sets of connecting components and snaps two adjacent guardrail units 100 together. The connecting components are fixedly connected to the first longitudinal beam 7, the first horizontal guardrail member 1 and the ground respectively by fasteners.

[0040] Structural principle:

[0041] The main structure of the traffic guardrail provided in this embodiment is attached... Figures 1-3As shown, the main body of the traffic barrier is composed of multiple barrier units 100 interconnected. Adjacent barrier units 100 are connected by a first longitudinal beam 7, forming a snap-fit ​​structure. This restricts the length of adjacent barrier units 100 by the first longitudinal beam 7, and fasteners securely connect the barrier units 100 to the first longitudinal beam 7, forming an integrated structure. This alternating connection of multiple barrier units 100 and the first longitudinal beam 7 allows for rapid installation along actual roads. Each barrier unit 100 itself employs a frame structure composed of multiple horizontally and vertically arranged structures. Specifically, it includes a first horizontal protective component 1 serving as a skin covering and connecting components that support the first horizontal protective components 1 on both sides and improve the overall structural strength. These connecting components are interlocked with the first longitudinal beam 7 to connect the multiple barrier units 100. The barrier is secured using fasteners, such as expansion bolts, to connect the structural components, including the connecting components and the first horizontal protective component 1, to the ground, thus firmly fixing the entire traffic barrier to the ground. This structure offers greater stability and better resistance to external forces compared to existing connectors that are plugged into the grid-type guardrail and placed on the road surface. Even in the event of a car collision, the traffic guardrail in this embodiment primarily deforms. Because the structural components are interconnected by fasteners to form a single unit, there is no flying debris. This effectively reduces the risk of damage to other vehicles or pedestrians caused by the guardrail structure flying or shifting during a traffic impact.

[0042] Example 2:

[0043] This embodiment is a further structural optimization based on Embodiment 1. See [link / reference]. Figure 2 and Figure 3 As shown, the connecting assembly includes a first crossbeam 4 and a third crossbeam 6 arranged sequentially from bottom to top. Both ends of the first crossbeam 4 are fixedly connected to adapter plates 41 for connecting to the first horizontal protective member 1. Each adapter plate 41 and the first horizontal protective member 1 have corresponding clearance holes 11. The first crossbeam 4 also has through holes for installing fasteners at positions corresponding to the clearance holes 11. Figure 3As shown, multiple sets of connecting components can be spaced apart on the same first horizontal guardrail 1. The shorter the distance between two adjacent connecting components, the higher the overall structural strength of the guardrail unit 100. Conversely, the longer the distance between two adjacent connecting components, the weaker the first horizontal guardrail 1's resistance to external impact or collision without support. The actual layout density of the connecting components can be flexibly selected according to the actual installation scenario. The adapter plate 41 is a structure used to improve the fit between the first crossbeam 4 and the first horizontal guardrail 1. Its main function is to realize the connection between the first crossbeam 4 and the first horizontal guardrail 1, so that the first horizontal guardrail 1 has a larger contact area and better support capacity when subjected to external forces. At the same time, it also facilitates better layout of fastener installation positions. Furthermore, since the first crossbeam 4 is the main skeleton structure constituting the frame structure, the first crossbeam 4 needs to be connected to the ground through fasteners. Therefore, in actual installation, fasteners such as collision bolts are inserted into the through holes of the first crossbeam 4 through the clearance holes 11 and into the blind holes drilled at the corresponding positions in the ground to achieve a fastening connection. After the first crossbeam 4 is connected to the ground, the first longitudinal beam 7 and the third crossbeam 6, which are fixedly connected to the first crossbeam 4 by fasteners, are fixed together with the first crossbeam 4. Then, the first horizontal protective component 1 is fixedly installed with fasteners, so that the entire traffic guardrail is firmly fixed to the ground.

[0044] Example 3:

[0045] This embodiment also provides another structural combination of the connecting components; see the specification. Figures 2-3 As shown, the connecting assembly includes a first crossbeam 4, a second crossbeam 5, and a third crossbeam 6 arranged sequentially from bottom to top. Each crossbeam includes a beam body 51, a locking groove 54 on the beam body 51 for accommodating and engaging the first longitudinal beam 7, and a side end face 52 for matching the structure of the first horizontal protective member 1 or the guardrail cover. The side end face 52 is provided with a connecting hole 53 for installing fasteners or connectors. The installation and connection principle of this embodiment is the same as that of embodiment 2, except that the structure of the connecting assembly adds a second crossbeam 5, so that the connecting assembly has three crossbeams in the longitudinal direction, making the structural support of the first horizontal protective member 1 more compact and its resistance to external forces stronger. Obviously, under the common guidance of this embodiment and embodiment 2, those skilled in the art can adjust the support strength of the first horizontal protective member 1 by increasing or decreasing the number of connecting assemblies in the length direction and increasing or decreasing the number of crossbeams constituting the connecting assembly in the height direction, so as to obtain combinations of traffic guardrails with different strength requirements. These will not be listed one by one in this embodiment. Regardless of the number of horizontal or vertical arrangements used by those skilled in the art, it should be understood as a technical solution that is not substantially different from this utility model.

[0046] Example 4:

[0047] This embodiment enhances the adaptability of traffic barriers to different application scenarios, laying the foundation for increasing the height of traffic barriers or installing auxiliary structural components. See details below. Figure 3 and Figure 9 As shown, the traffic guardrail provided in this embodiment further includes a second horizontal protective member 2 based on any of the above embodiments. The second horizontal protective member 2 has through slots at both ends for accommodating and engaging the first longitudinal beam 7. The second horizontal protective member 2 is fixedly connected to the first longitudinal beam 7 and / or the first horizontal protective member 1 by fasteners. The second horizontal protective member 2 can adopt an open slot structure to seal the top of the traffic guardrail, and simultaneously serve as a mounting base for installing other heightening structures. Reflectors or light-blocking plates can be installed on the second horizontal protective member 2 to provide traffic guidance for vehicles traveling in the same direction and to block the lights of oncoming vehicles, respectively.

[0048] In this embodiment, to further enhance its usability, the first longitudinal beam 7 extends upward above the first horizontal protective member 1 and is plugged into or fixedly connected to the third horizontal protective member 3. See also... Figure 3 and Figure 9 As shown.

[0049] As an alternative method to enhance strength, see Figure 3 As shown, at least a plurality of second longitudinal beams 8 are installed between the third horizontal protective member 3 and the first horizontal protective member 1. Alternatively, at least a plurality of second longitudinal beams 8 are installed between the third horizontal protective member 3 and the second horizontal protective member 2.

[0050] To facilitate connection, adjacent guardrail units 100 are connected. In this embodiment, the cross-section of the first longitudinal beam 7 is I-shaped, such as... Figure 8 As shown.

[0051] To further reduce damage caused by external collisions, this embodiment also includes anti-collision structures fixedly connected to both ends of the guardrail. The anti-collision structure can adopt existing technology or the following structure: The anti-collision structure includes multiple vertically installed and rotatable anti-collision cylinders. When a car loses control and crashes into the guardrail, the anti-collision cylinders can disperse the impact force of the car and guide it into the lane, preventing the car from losing control and overturning the guardrail, causing greater damage.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
