Description

Technical Field

[0001] The utility model belongs to the technical field of traffic safety, and in particular relates to a beam-column type guardrail end structure. Background Art

[0002] In modern urban construction and road traffic engineering, beam-column guardrails are an important traffic safety facility and are widely used in key traffic areas such as highways, urban roads and bridges. This type of guardrail provides a strong guarantee for driving safety through the stable connection between the column and the beam. However, in actual use, the end structure of traditional beam-column guardrails often becomes a weak link of safety hazards.

[0003] The end design of traditional beam-column guardrails is mostly simple and direct, lacking special anti-collision and buffering measures. When a vehicle accidentally hits the end of the guardrail, the impact force cannot be effectively dispersed and absorbed, which often causes serious damage to the vehicle and even casualties. In addition, although some designs take safety into consideration, they use expensive materials such as anti-collision pads, which increases engineering costs and is not conducive to widespread promotion and application. Utility Model Content

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the present invention, the specific implementation method, structure, characteristics and effects of the vehicle warning system for the interchange entrance proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] Example 1

[0028] like Figure 1-2 As shown, a beam-column guardrail end structure in this embodiment includes a guardrail end 1 and a standard section 2; the guardrail end 1 and the standard section 2 are connected by welding; the two parts are tightly connected by high-strength welding, ensuring stability and reliability in various traffic environments.

[0029] The guardrail end 1 is composed of a plurality of beams and is arranged in an inclined shape; the beams are arranged in parallel and gradually change toward the ground in sequence.

[0030] This part adopts a structure of multiple beams, and these beams are not set horizontally as traditionally, but are inclined; the inclined design not only enhances the visual effect of the guardrail end 1 and makes it more beautiful, but more importantly, it can guide the impact force upward and disperse it when a vehicle collides, reducing direct damage to the vehicle and occupants.

[0031] A beam-column guardrail end structure in this embodiment effectively improves the safety and practicality of the guardrail at the end through ingenious design.

[0032] Example 2

[0033] Based on Example 1, please refer to Figure 1 There are three crossbeams, which include crossbeam 1 11, crossbeam 2 12 and crossbeam 3 13 respectively; wherein:

[0034] The center distance between the cross beam 1 11, the cross beam 2 12 and the cross beam 3 13 is 900-1200 cm. This spacing design not only ensures the stability of the structure, but also ensures the effective dispersion of the impact force when the vehicle collides.

[0035] The beam-column guardrail end structure in this embodiment achieves multiple goals of safety, beauty, economy and practicality through fine design and reasonable layout. This structure can not only effectively improve the safety of road traffic, but also provide drivers with clearer and more specific visual guidance, which is an indispensable and important part of modern traffic engineering.

[0036] Furthermore, the column base 3 at one end of the beam 1 11, the beam 2 12 and the beam 3 13 is fixed to the ground by the embedded bolt 4, and the other end is connected to the guardrail of the standard section 2 respectively;

[0037] In this embodiment, the column base 3 is firmly fixed to the ground by embedded bolts 4, ensuring the overall stability of the guardrail end 1, and the other end is connected to the guardrail of the standard section 2 by welding or other high-strength connection methods, forming a continuous and stable guardrail system.

[0038] Furthermore, the lengths of the beam 1 11, the beam 2 12 and the beam 3 13 decrease in sequence;

[0039] The outward extension distance from the center of one end of the crossbeam 11 to the outside of the lane is not less than 25 cm.

[0040] The lengths of the first beam 11, the second beam 12 and the third beam 13 decrease in sequence. The above design not only meets the visual aesthetic requirements, but more importantly, it can gradually absorb and disperse the impact force when a vehicle collides, thereby reducing the damage to the vehicle and the occupants. At the same time, the decreasing length design of the beams also matches the overall inclined setting, making the guardrail end 1 more visually smooth and more functionally reasonable.

[0041] It should be noted that the end 1 of the guardrail should be extended outward to the outside of the lane if construction conditions permit, and the minimum extension width should not be less than 25 cm. In the reconstruction project, if there is no extension condition, auxiliary facilities such as water barriers or anti-collision barrels can be installed at the end to ensure the safety of the end 1 of the guardrail.

[0042] Furthermore, the length of the guardrail end 1 is 3 meters; the crossbeams gradually change toward the ground, and the center spacing and gradient rate of the crossbeams are determined according to the setting height of the guardrail.

[0043] Furthermore, the end 1 of the guardrail is affixed with a yellow and black reflective film 5. In order to enhance the visibility of the guardrail at night or in low visibility conditions, the end 1 of the guardrail is affixed with a yellow and black reflective film 5. The reflective film 5 is preferably a reflective film 5 of Class V; it can produce a strong reflective effect under light, reminding drivers to pay attention to road safety and reducing the incidence of traffic accidents.

[0044] The present invention is further described in conjunction with the embodiments, but the present invention is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
