Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of guardrails, more specifically, relates to a guardrail structure and a bridge. BACKGROUND
[0002] As an indispensable safety facility in road and bridge structures, crash barriers primarily function to prevent vehicles from running off the road or bridge boundaries, thereby effectively avoiding or reducing personnel casualties and property losses resulting therefrom. These guardrails not only provide necessary physical barriers for vehicles in motion, but also greatly reduce the risk of secondary accidents caused by unexpected deviation from the normal trajectory of the vehicle.
[0003] Traditional crash barrier designs mainly focus on the effective interception of large-volume objects such as vehicles, using robust structures and materials to withstand high-speed impacts and ensure the safety of vehicles and passengers. However, in practical applications, such barriers often have poor interception effects on smaller objects such as road debris and gravel. These small objects, due to their small size and light weight, can easily pass through or roll over the barriers, potentially posing a threat to pedestrians, vehicles, or other road users below. SUMMARY
[0004] The purpose of the embodiments of the present application is to provide a guardrail structure and a bridge to solve the technical problem of poor interception of small-volume objects by existing guardrails.

[0037] As shown in Figure 1 and Figure 3 , the present application provides a guardrail structure, which comprises guardrail posts 1, net posts 2 and a first safety net 3.
[0038] Among them, the guardrail post 1 is the supporting foundation of the whole structure, and its number is set to multiple according to actual needs. These guardrail posts 1 are installed on the external foundation in turn along the extension direction of the external foundation (such as roadbed, bridge foundation, etc.). The external foundation can be pre-buried with bolts, and the stable connection between the guardrail post 1 and the external foundation is realized through the pre-buried bolts.
[0039] The net post 2 is used to support the first safety net 3. The net post 2 extends in the vertical direction, which can provide sufficient support force to ensure that the first safety net 3 can be effectively unfolded and maintain its shape.
[0040] One end of the first safety net 3 is connected to one net post 2, and the other end of the first safety net 3 is connected to another net post 2, thereby forming a continuous safety net surface on the guardrail to effectively intercept and prevent small-volume objects such as debris and gravel from crossing the guardrail, not only improving the safety of the road or bridge, but also reducing the risk of traffic accidents caused by objects falling.
[0041] As shown in Figure 1 and Figure 3 , in one specific embodiment of the present application, the guardrail structure further comprises a guardrail cross beam 4. The extension direction of the guardrail cross beam 4 is the same as that of the external foundation, and the guardrail cross beam 4 is connected to the guardrail post 1. This connection mode not only enhances the overall rigidity of the guardrail structure, but also effectively improves its bearing capacity when facing external force impact.
[0042] As shown in Figure 1 and Figure 3As shown in the drawings, in one embodiment of the present application, the number of guardrail cross beams 4 is multiple, so as to further increase the structural strength of the guardrail structure. The guardrail cross beams 4 are arranged in sequence and at intervals along the height direction of the guardrail upright 1, which can not only ensure the permeability of the guardrail structure, but also improve the overall carrying capacity.
[0043] As shown in the drawings, Figure 1 and Figure 3 As shown in the drawings, in one embodiment of the present application, the guardrail structure further comprises a second anti-throwing net 5. One end of the second anti-throwing net 5 is connected to one guardrail cross beam 4, and the other end of the second anti-throwing net 5 is connected to another guardrail cross beam 4. The second anti-throwing net 5 is arranged between the two guardrail cross beams 4, which can prevent small-volume objects such as debris and gravel from passing through between the two guardrail cross beams 4, thereby further improving the interception and blocking capacity of the guardrail structure for small-volume objects.
[0044] In one embodiment of the present application, an L-shaped angle steel is further arranged on the guardrail cross beam 4. One edge of the L-shaped angle steel is attached to and welded on the guardrail cross beam 4. The edge of the L-shaped angle steel is arranged in parallel with the second anti-throwing net 5, and the second anti-throwing net 5 is connected to the edge of the L-shaped angle steel through bolts.
[0045] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, in one embodiment of the present application, the guardrail upright 1 comprises a base plate 11, a web plate 12 and a top plate 13. The base plate 11 is arranged at the bottom end of the web plate 12, and the base plate 11 is connected to the external foundation to provide a support foundation for the entire guardrail structure. The web plate 12 serves as the main part of the guardrail upright 1, and functions to connect the base plate 11 and the top plate 13. The web plate 12 is tapered from narrow to wide, and has a trapezoidal structure. The top plate 13 is arranged at the top end of the web plate 12, and provides a connection and installation platform for the anti-throwing net upright 2. The top plate 13 and the anti-throwing net upright 2 can be connected through bolts or welding, so as to ensure that the anti-throwing net upright 2 can be stably connected to the top plate 13.
[0046] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, in one embodiment of the present application, the guardrail upright 1 further comprises an inner side plate 14 and an outer side plate 15. The inner side plate 14 is arranged at one transverse end of the web plate 12, and faces the inner side of the road or bridge. The outer side plate 15 is arranged at the other transverse end of the web plate 12, and the guardrail cross beam 4 is connected to the inner side plate 14, which faces the outer side of the road or bridge. The inner side plate 14 and the outer side plate 15 are both used to improve the structural strength and bending resistance of the web plate 12.
[0047] As shown in the drawings, Figure 1 and Figure 2As shown, in one specific embodiment of the present application, the guardrail post 1 further comprises a plurality of stiffening plates 16, each of which is connected to the web 12 along the height direction of the web 12. The stiffening plates 16 can provide additional support and reinforcement at the key stress positions of the web 12. By evenly or as needed distributing these stiffening plates 16 along the height direction of the web 12, the load on the web 12 can be effectively dispersed, thereby improving the overall stiffness and load-carrying capacity of the guardrail post 1.
[0048] The present application also provides a bridge comprising the guardrail structure in the above-mentioned embodiments, and thus has the advantages of the guardrail structure in the above-mentioned embodiments.
[0049] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
