Description

Technical Field

[0001] The utility model relates to the technical field of highways, in particular to a metal beam-column type guardrail anti-trampling facility and a safety guardrail. Background Art

[0002] In order to ensure the safety of vehicles and pedestrians on urban bridges and avoid serious casualties and property losses caused by vehicles losing control and falling under the bridge or rushing into the opposite lane, urban bridges should be reasonably equipped with anti-collision guardrails according to the requirements of the regulations. Commonly used bridge guardrails include concrete guardrails, combined guardrails, and metal beam-column guardrails. Among them, metal beam-column guardrails have the characteristics of high safety protection performance, good vehicle roll control effect, light weight, etc. At the same time, the shape is simple, transparent and beautiful. Therefore, urban bridges mostly use metal beam-column guardrails.

[0003] Most of the metal beam-column guardrails currently in use have a crossbeam as the main collision surface. However, there are many pedestrians on urban bridges, and there is a safety hazard that pedestrians or children may step on the crossbeam and climb over the guardrail. Utility Model Content

[0004] In view of the above-mentioned existing problems, the utility model provides a metal beam-column guardrail anti-trampling facility and a safety guardrail. By arranging an anti-trampling net between the crossbeams of the metal beam-column guardrail, it can effectively prevent pedestrians from stepping on the crossbeams and climbing over the guardrail while maintaining the protective function of the guardrail, thereby improving the safety performance.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] As a further implementation method, the anti-trampling net is installed on the collision surface of the crossbeam to prevent pedestrians from stepping on and climbing over the exposed part of the crossbeam.

[0008] As a further implementation, the anti-trampling net is fixedly connected to the column via a connecting piece.

[0009] As a further implementation method, the aperture of the anti-trampling net is no more than 5 cm to prevent pedestrians from stepping on the guardrail beam.

[0010] As a further implementation method, the anti-trampling net is arranged in sections, and both ends of each section of the anti-trampling net are respectively fixed to two adjacent columns through connecting pieces.

[0011] As a further implementation method, the anti-trampling net is provided with a rigid frame around it to facilitate the support and installation of the anti-trampling net; the anti-trampling net is bolted to the connecting member via the rigid frame.

[0012] As a further implementation method, the connecting member includes a connecting vertical plate and a connecting bottom plate. A bolt hole is provided at one end of the connecting vertical plate close to the rigid frame, and the connecting vertical plate is placed close to the side of the rigid frame. The bolt holes on the side of the connecting vertical plate correspond to those on the rigid frame and are fixedly connected by bolts. The other end of the connecting vertical plate is connected to the column via the connecting bottom plate.

[0013] As a further implementation method, the connecting plate is in a horizontal T-shape to increase the contact area between the connecting plate and the rigid frame. The bolt holes are arranged at the top and bottom of the connecting plate to ensure that the anti-stepping net is securely installed to prevent it from being lifted up and to improve the connection strength.

[0014] As a further implementation method, the connecting vertical plate is connected to the connecting bottom plate by welding; the connecting bottom plate is attached to the front side of the column and is connected to the column by welding.

[0031] In a typical embodiment of the present application, a metal beam-column guardrail anti-trampling facility is provided, such as Figure 1-7As shown, a metal beam-column guardrail anti-trampling facility includes a metal beam-column guardrail of a guardrail base 1, columns 3 and beams 2. The columns 3 are made of steel, and multiple columns 3 are evenly arranged at the same distance. The bottom of the columns 3 is fixed to the top of the guardrail base 1; the beam 2 is a rectangular steel pipe, which is perpendicular to the columns 3 and installed on the collision surface of the columns 3 to play a protective role. Multiple beams 2 are arranged in parallel from top to bottom, and multiple columns 3 support multiple beams 2 to form an anti-collision guardrail facility. In this embodiment, an anti-trampling net 4 is arranged between the guardrail base 1 and the beam 2 and between adjacent beams 2. The anti-trampling net 4 blocks the guardrail area so that there is no gap between the beams 2 and the bottom, which can effectively prevent pedestrians from climbing over the guardrail by stepping on the guardrail base 1 or the beam 2 to prevent safety accidents.

[0032] like Figure 2-3 As shown, the anti-trampling net 4 is fixedly installed on the column 3. Specifically, since the bridge usually has a large span, in order to facilitate installation and save costs, the anti-trampling net 4 is arranged in sections, and each section of the anti-trampling net 4 is arranged between two adjacent columns 3, and the two ends of each section of the anti-trampling net 4 are fixed to the column 3 through the connecting piece 5. At the same time, in order to achieve a better safety protection effect, the anti-trampling net 4 is installed on the collision surface of the beam 2, that is, the side of the guardrail facing the bridge deck, so that the anti-trampling net 4 is flush with the edge of the collision surface of the beam 2 or protrudes from the edge of the beam 2, ensuring that pedestrians cannot step on and climb over the guardrail through the exposed part of the beam 2 on the outside. Figure 4 As shown, the aperture of the anti-trampling net 4 is no more than 5 cm to prevent pedestrians from stepping on the guardrail beam 2; the anti-trampling net 4 is surrounded by a rigid frame 41, which is made of steel and has a certain thickness to facilitate the support and installation of the anti-trampling net. Figure 5 As shown, a first bolt hole 42 is provided on the side of the rigid frame 41, and in order to ensure secure installation, at least a first bolt hole 42 needs to be provided at the top and bottom ends of the rigid frame 41 respectively to prevent the anti-trampling net 4 from being lifted up from the top or bottom surface and losing its protective function. The anti-trampling net 4 is bolted to the connecting piece 5 through the rigid frame 41, so that the anti-trampling net 4 is fixedly installed on the column 3 through the connecting piece 5.

The connecting vertical plate 52 is provided with a second bolt hole 53 at one end close to the rigid frame 41, and is placed close to the side of the rigid frame 41. The second bolt hole 53 is provided corresponding to the first bolt hole 42 to achieve connection and fixation with the bolt 6. Specifically, the connecting vertical plate 52 is in a horizontal T-shape, so that the end of the connecting vertical plate 52 connected to the rigid frame 41 has a certain length, which can increase the contact area between the connecting vertical plate 52 and the rigid frame 41, so that the connecting vertical plate 52 and the rigid frame 41 can selectively set multiple bolt holes between the top bolt hole and the bottom bolt hole to improve the connection strength.

[0034] The other end of the connecting plate 52 is welded with a connecting bottom plate 51, and the connecting member 5 is fixedly connected to the column 3 through the connecting bottom plate 51. Figure 3 As shown, the connecting bottom plate 51 is attached to the front of the column 3 and is fixedly connected to the column 3 by welding. In addition, in order to facilitate welding, the connecting plate 52 and the connecting bottom plate 51 are respectively made of steel, and the material grade is consistent with the column 3 of the guardrail.
