Description

Technical Field

[0001] This utility model relates to the field of traffic facility technology, and in particular to road motor vehicle lane isolation guardrails, specifically traffic isolation guardrails. Background Technology

[0002] As a crucial facility in modern urban traffic management systems, traffic barriers have evolved from simple safety protection into comprehensive facilities that combine functionality and aesthetics. Functionally, barriers physically separate traffic flow, clearly defining spaces for motor vehicles, non-motorized vehicles, and pedestrians, reducing traffic accidents caused by mixed traffic and curbing violations such as arbitrary lane changes and driving against the flow of traffic. In terms of safety, barriers not only cushion vehicle accidents and reduce injuries, but also effectively prevent pedestrians from crossing the road, significantly enhancing pedestrian safety, especially in densely populated areas such as school campuses and commercial districts. Furthermore, their directional design uses visual elements such as color and reflective markings to guide the behavior of road users, playing a crucial warning role in complex road sections and at night.

[0003] Currently, the construction and application of traffic safety barriers have formed a standardized system. In terms of material selection, high-strength materials such as galvanized steel, stainless steel, and aluminum alloys have become mainstream, balancing durability and corrosion resistance, while concrete and composite materials are also widely used in specific scenarios. In terms of design, modern barriers break through traditional functional limitations, incorporating regional cultural symbols and adopting streamlined appearances to make the facilities an organic part of the urban landscape—antique stone and wood structures are common in historical districts, while modern metal materials are often used in commercial centers, achieving a unity of practical and aesthetic value. Regarding installation and maintenance, diverse installation methods such as ground embedding and wall mounting adapt to different road conditions, coupled with regular inspections and rapid replacement mechanisms for damaged sections, ensuring the long-term effectiveness of the barriers. It is worth noting that some cities have piloted intelligent barrier systems, which integrate sensors and data modules to monitor traffic flow in real time, marking an upgrade from passive protection to proactive management of the facilities.

[0004] Based on actual usage, there are two main types of guardrails: one is the railing-style guardrail used on narrow roads or roads with relatively few lanes. Its structure mainly consists of welded, one-piece railings and metal bases connecting the railings. The biggest advantage of this type of guardrail is its ease of installation; simply nest the railings to the metal base. However, its disadvantage is also very obvious: it doesn't connect to the road surface, making it prone to penetrating injuries in the event of a traffic accident due to its structure, which can easily cause fatal injuries to drivers, passengers, or pedestrians. The other type uses a concrete base with railings installed on it. The advantage of this type of guardrail is its heavy weight and strong stability under external forces. Its disadvantages are that transportation and installation require specialized equipment for hoisting, resulting in high installation and transportation costs and a long manufacturing cycle. Furthermore, it has poor stability on uneven road surfaces. Utility Model Content

[0005] To address the issues of low stability, safety hazards, or difficulties in installation and transportation of existing traffic safety barriers, this application provides an alternative traffic safety barrier that balances ease of transportation and installation with stability, aiming to overcome the shortcomings of existing barriers.

[0006] The advantages of this utility model compared to existing traffic guardrails are:

[0007] 1. Adopting a brand-new frame skin structure, it can simultaneously ensure the stability and safety of the guardrail. At the same time, the overall structure is lightweight and easy to transport. During installation, fasteners are used to firmly connect different structural components, making the guardrail's overall stability and resistance to external forces strong.

[0008] 2. After installation, this utility model forms a fixed connection with the road. The entire guardrail is an integrated metal frame structure, which greatly reduces the probability of structural components scattering and injuring surrounding vehicles and pedestrians in the event of a traffic collision. The guardrail is fully covered on the outside, and the overall structure is aesthetically pleasing.

[0009] 3. This utility model also provides anti-collision guide barrels at the ends of the guardrails, which can change the direction of collision as much as possible in the event of a traffic accident, reduce the stress of direct collision, and reduce the damage and loss caused by traffic accidents.

[0010] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0011] A traffic safety barrier includes multiple connecting joints that are spaced apart and detachably fixed to the road; guardrails that are detachably fixed to both sides of the connecting joints and used to connect two adjacent connecting joints; and end posts fixed to the ends of the interconnected guardrails. The bottom of each end post is detachably fixed to the road. The connecting joints can be located at both ends of a single guardrail as joint structures connecting two adjacent guardrails, but one or more connecting joints can also be installed in the middle of the guardrail. Their function is to improve the guardrail's resistance to external forces and prevent deformation under stress. The aforementioned installation of protective plates on both sides of the connecting joints refers to the fixed installation of protective plates on both the left and right sides of each connecting joint along the length of the guardrail. However, in addition to the two ends, the middle of any single protective plate can also be fitted with multiple connecting joints. The more connecting joints installed and the smaller the distance between two adjacent connecting joints, the stronger the support of the protective plate and the better its resistance to external impact. Conversely, if only the two ends of the protective plate are fitted with connecting joints, although the entire guardrail can be connected into one unit, there is no load-bearing structure in the middle of a single protective plate. In this case, if the length of the protective plate is long, its resistance to external forces will be weakened.

[0012] As one of the main improvements of this utility model, the connecting joint has multiple structural configurations. Preferably, the connecting joint includes a base plate for connecting to the road, a longitudinal beam vertically installed on the base plate, and side plates installed on both sides of the longitudinal beam along the length of the base plate. The side plates are detachably and fixedly connected to the guardrail. The base plate is fixedly connected to the road via standard connectors, such as expansion bolts. The longitudinal beam, as the main load-bearing and connecting structure, provides support for the installation of the side plates. The side plates are used to fix the guardrail, which serves as the guardrail skin or surface covering, making the guardrail and the entire connecting structure an integrated structure, thus firmly fixing the entire guardrail to the road. This frame-skin combination structure guardrail is lightweight, high-strength, and has good installation flexibility. The side plates can meet the installation requirements of guardrails with different inclinations and solve the installation problems of guardrails with different shapes, allowing the assembled guardrail cross-section to be of various shapes, such as square, rectangular, trapezoidal, triangular, frustum, etc.

[0013] To improve the ease of installation of the protective plate, preferably, at least one side of the side plate is provided with a second bend for close contact and connection with the protective plate. Of course, for ease of installation and considering uniform stress distribution, two second bends are generally symmetrically arranged. The second bend has holes / grooves for installing fasteners or a snap-fit ​​structure for engaging with the protective plate. The specific structure of the second bend can be flexibly designed. For example, when the second bend is fixed by bolts or screws, it can be connected by through holes, threaded holes, or U-grooves; when the second bend and the protective plate are connected using a tool-less installation structure, a matching snap-fit ​​connector / groove can be used for connection.

[0014] To facilitate better installation and achieve distributed connection and fixation of the guardrail panels, thereby addressing the issue of concentrated stress and improving the overall strength of the guardrail, the base plate preferably includes a flat portion at the bottom for connection with the road. Both ends of the flat portion are turned outwards to form first bent portions for close contact and connection with the guardrail panels. The first bent portions are connected to the guardrail panels in the same way; they can be matched with snap-fit ​​mechanisms based on the structure of the guardrail panels, or fasteners can be used for connection. The aim is to allow for fastening at different points on the guardrail panels, thereby improving the overall resistance to external forces.

[0015] As another structural arrangement to enhance the overall strength of the guardrail, preferably, two connecting joints are installed side by side. Each connecting joint has an opening groove along its length on the side of the longitudinal beam closest to the adjacent connecting joint. A post for connecting two adjacent longitudinal beams is installed within the opening groove. The post can be vertically inserted into and connect two adjacent longitudinal beams through the opening groove. This allows the same connecting joint to connect only one guardrail plate, rather than two adjacent guardrail plates simultaneously, by connecting two adjacent connecting joints together through the post. This enables diverse installation options and is more conducive to modular installation. It even allows the connecting joints and guardrail plates to be pre-assembled into components before being transported to the construction site for installation and assembly, further improving installation efficiency.

[0016] To balance ease of installation and structural strength requirements, preferably, the column comprises an integrally formed body and enlarged portions on both sides of the body extending along the thickness direction to engage the longitudinal beams. The specific structure of the enlarged portions is not limited, as long as they can engage the longitudinal beams or form an effective connection structure to securely connect two adjacent longitudinal beams; for example, a straight extension forming an "I" shape.

[0017] More preferably, in order to meet the different requirements for guardrail height on different road sections, a railing structure is installed on the top of the guardrail. The railing structure includes a first horizontal beam and a second horizontal beam arranged horizontally. The first horizontal beam and the second horizontal beam are fixedly connected by a column and / or a reinforcing member fixed to the connecting joint.

[0018] Furthermore, in order to enhance the functionality of the guardrail and meet the needs of various road conditions and scenarios, preferably, the guardrail structure is provided with multiple light-blocking plates for blocking oncoming light and / or providing reflective markings.

[0019] In a further preferred embodiment, a fixed bracket is also connected to the outer side of the end post, and multiple guide barrels for anti-collision are rotatably mounted on the fixed bracket.

[0020] Further preferably, the end post is also provided with reflective markings and / or traffic information interaction devices, as well as photovoltaic panels for generating solar power and supplying power to the traffic information interaction devices.

[0021] Beneficial effects:

[0022] 1. This utility model adopts a brand-new frame skin structure, which can simultaneously ensure the stability and safety of the guardrail. At the same time, the overall structure is lightweight and easy to transport. During installation, fasteners are used to firmly connect different structural components, making the overall stability and resistance to external forces of the guardrail strong.

[0023] 2. After installation, this utility model forms a fixed connection with the road. The entire guardrail is an integrated metal frame structure, which greatly reduces the probability of structural components scattering and injuring surrounding vehicles and pedestrians in the event of a traffic collision. The guardrail is fully covered on the outside, and the overall structure is aesthetically pleasing.

[0024] 3. This utility model also provides anti-collision guide barrels at the ends of the guardrails, which can change the direction of collision as much as possible in the event of a traffic accident, reduce the stress of direct collision, and reduce the damage and loss caused by traffic accidents.

[0039] Example 1:

[0040] This embodiment provides a traffic safety barrier; please refer to the attached instruction manual. Figure 1As shown in the central structure, it includes multiple connecting joints 1 that are spaced apart and detachably fixed to the road; guard plates 2 that are detachably fixed to both sides of the connecting joints 1 and used to connect two adjacent connecting joints 1; and end posts 3 fixedly installed at the ends of the multiple interconnected guard plates 2. The bottom of the end posts 3 is detachably fixed to the road. The connecting joints 1 can be located at both ends of a single guard plate 2 as joint structures connecting two adjacent guard plates 2, but one or more connecting joints 1 can also be installed in the middle of the guard plate 2. Their function is to improve the strength of the guard plate 2 against external forces and prevent deformation under stress. The aforementioned installation of guardrail plates 2 on both sides of the connecting joint 1 means that guardrail plates 2 are fixedly installed on both sides of the guardrail along its length for covering any connecting joint 1. However, in addition to the two ends, the middle of any guardrail plate 2 can also be fitted with multiple connecting joints 1. The more connecting joints 1 installed and the smaller the distance between two adjacent connecting joints 1, the stronger the support of the guardrail plate 2 and the better its resistance to external impact. Conversely, if only the two ends of the guardrail plate 2 are fitted with connecting joints 1, although the entire guardrail can be connected into one piece, the middle position of a single guardrail plate 2 lacks a load-bearing structure. In this case, if the length of the guardrail plate 2 is long, its resistance to external forces will be weakened. The connecting joint 1 serves as a frame fixed to the road, and the guardrail plate 2 serves as a covering component fixedly covering the connecting joint 1, which can be combined to form a guardrail structure with high strength, full coverage, and aesthetic appeal. Compared to existing guardrails, this type of railing offers significantly improved stability on the road, preventing displacement or movement under external forces. Furthermore, compared to concrete guardrails, it is significantly lighter, making transportation and installation more convenient. Installation can be completed without the need for special hoisting equipment. Most importantly, it exhibits good compatibility with road surface unevenness, ensuring secure installation even on uneven road surfaces.

[0041] Example 2:

[0042] This embodiment proposes a better and more specific improvement to the structure of the connecting joint 1 based on embodiment 1. As one of the main improvements of this utility model, the connecting joint 1 has multiple structural configurations, see [link to relevant documentation]. Figure 2As shown, the connecting joint 1 includes a base plate 101 for connecting to the road, a longitudinal beam 102 vertically installed on the base plate 101, and side plates 103 respectively installed on both sides of the longitudinal beam 102 along the length of the base plate 101. The side plates 103 are detachably and fixedly connected to the guardrail 2. The base plate 101 is fixedly connected to the road through standard connectors, such as expansion bolts. The longitudinal beam 102 provides support for the installation of the side plates 103 as the main load-bearing and connecting structure. The guardrail 2, which serves as the guardrail skin or surface covering, is fixedly connected to the side plates 103, so that the guardrail 2 and the entire connecting joint 1 form an integrated structure, thereby firmly fixing the entire guardrail to the road. This frame-skin combination structure guardrail is lightweight, high-strength, and has good installation flexibility. The side plates 103 can meet the installation requirements of guardrails 2 with different inclinations and solve the installation problems of guardrails 2 with different shapes, so that the cross-section of the assembled guardrail can be of various shapes, such as square, rectangular, trapezoidal, triangular, frustum, etc.

[0043] Example 3:

[0044] To improve the ease of installation of the protective plate 2, this embodiment further improves upon embodiment 2. At least one side of the side plate 103 is provided with a second bending portion 1031 for attaching and connecting with the protective plate 2. Of course, for ease of installation and considering uniform stress distribution, two second bending portions 1031 are generally symmetrically arranged. See [reference needed]. Figure 2 As shown, the second bent portion 1031 is provided with holes / grooves for installing fasteners or with a snap-fit ​​structure for engaging with the guard plate 2. The specific structure of the second bent portion 1031 can be flexibly configured. For example, when the second bent portion 1031 is fixedly connected by bolts or screws, it can be connected by opening through holes, threaded holes, or U-grooves; when the second bent portion 1031 and the guard plate 2 are connected using a tool-less installation structure, a matching snap-fit ​​connector / groove can be provided to achieve the connection.

[0045] To facilitate better installation and achieve distributed connection and fixation of the guardrail 2, thereby addressing the issue of concentrated stress and improving the overall strength of the guardrail, in this embodiment, the base plate 101 includes a flat portion 1011 located at the bottom for connection with the road. Both ends of the flat portion 1011 are folded outwards to form first bent portions 1012 for attachment and connection with the guardrail 2. For example... Figure 2 As shown, the first bent portion 1012 is connected to the guard plate 2 in the same way. It can be matched with a snap-fit ​​mechanism according to the structure of the guard plate 2, or it can be connected using fasteners. The purpose is to allow for fastening at different points on the guard plate 2, thereby improving the overall resistance to external forces of the guard plate 2.

[0046] Example 4:

[0047] This embodiment is a further improvement on embodiments 2-3. This embodiment presents another structural design for connection joint 1 to enhance the overall strength of the guardrail. See the appendix of the instruction manual for details. Figures 3-6 As shown, in this embodiment, two connecting joints 1 are installed side by side. Each connecting joint 1 has a slot 1021 along its length on the side of its longitudinal beam 102 closest to the adjacent connecting joint 1. A column 5 for connecting two adjacent longitudinal beams 102 is installed within the slot 1021. The column 5 can be vertically inserted into and connect two adjacent longitudinal beams 102 through the slot 1021. This allows the same connecting joint 1 to connect to only one adjacent guard plate 2, rather than simultaneously connecting two adjacent guard plates 2. The column 5 connects two adjacent connecting joints 1 together, enabling the invention to support diverse installation methods. This is more conducive to modular installation, and the connecting joint 1 and guard plate 2 can even be pre-assembled into a component before being transported to the construction site for installation and assembly, further improving installation efficiency.

[0048] To balance ease of installation and structural strength requirements, in this embodiment, the column 5 includes an integrally formed body 51 and enlarged portions 52 disposed on both sides of the body 51 and extending along the thickness direction to form a locking mechanism for engaging the longitudinal beam 102. The specific structure of the enlarged portions 52 is not limited, as long as they can achieve the locking mechanism for the longitudinal beam 102 or form an effective connection structure to securely connect two adjacent longitudinal beams. For example, a straight extension forming an "I" shape is acceptable.

[0049] Furthermore, in order to meet the different requirements for guardrail height on different road sections, a railing structure is installed on the top of the guardrail 2. The railing structure includes a first horizontal beam 4 and a second horizontal beam 7 arranged horizontally. The first horizontal beam 4 and the second horizontal beam 7 are fixedly connected by a column 5 and / or a reinforcing member 6 fixed to the connecting joint 1.

[0050] Furthermore, to enhance the functionality of the guardrail and meet the needs of various road conditions and application scenarios, in this embodiment, the guardrail structure is equipped with multiple light-blocking plates 8 for blocking oncoming light and / or providing reflective markings. The size, height, and structure of the light-blocking plates 8 can be flexibly changed according to different usage scenarios.

[0051] Furthermore, a fixed bracket 12 is connected to the outer side of the end post 3, and multiple guide barrels 11 for anti-collision are rotatably mounted on the fixed bracket 12. The guide barrels 11 are rotatably mounted on the fixed bracket 12, and their purpose is to minimize the loss and damage caused by the impact when a vehicle accidentally hits the guardrail. The guide barrels 11 have the function of guiding and dissipating force to avoid serious damage and injury to vehicles and people caused by rigid collisions, and to minimize the loss of traffic accidents.

[0052] Further preferably, the end post 3 is also provided with reflective markings and / or a traffic information interaction device 9, as well as a photovoltaic panel 10 for generating solar power and supplying power to the traffic information interaction device 9. The reflective markings can be unchanging suggestive or warning signs, such as driving direction signs, speed limit signs, etc.; the traffic interaction device 9 is an electronic screen that can provide various traffic information. This part can be integrated into this utility model using existing products to improve the functionality of this utility model and maximize the convenience of traffic.

[0053] 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.
