[0040] Opening 201 Specific implementation mode
[0041] The present utility model will be further described below in conjunction with the accompanying drawings by way of embodiments, but the present utility model is not limited to the scope of the embodiments thereby.
[0042] As Figures 1-3 shown, this embodiment provides a temporary anti-collision guardrail 100 at the bridge opening. The temporary anti-collision guardrail 100 at the bridge opening is used to surround the opening 201 left after the beam is removed during the replacement construction of small box girders, slab girders, etc. on the bridge 200. When in use, multiple temporary anti-collision guardrails 100 at the bridge opening are usually connected and arranged around the opening 201.
[0043] Although this embodiment only illustrates the situation where the temporary anti-collision guardrail 100 at the bridge opening is used for the protection of the opening 201 of the bridge 200. However, the present utility model is not limited thereto, and the temporary anti-collision guardrail 100 at the bridge opening can also be used for the protection of the opening 201 that appears on the road or in large buildings.
[0044] The temporary anti-collision guardrail 100 at the bridge opening includes: a base 110, a sight shield 140, a column 120, and an energy dissipation component.
[0045] The column 120 is fixed above the base 110. The sight shield 140 is arranged on the first side of the column 120, and the energy dissipation component is arranged on the second side of the column 120, where the second side is opposite to the first side.
[0046] The temporary anti-collision guardrail 100 at the bridge opening is provided with a sight shield 140 to block the view of the bridge opening 201, preventing the drivers on the bridge 200 from seeing the opening 201 and causing psychological fear. At the same time, an energy dissipation component is arranged on the second side. When a vehicle collides with the guardrail, a large amount of kinetic energy of the vehicle is absorbed by the energy dissipation component, reducing the impact damage to the column 120 caused by the energy. Meanwhile, the impact force of the vehicle collision is reduced, making the collision more gentle.
[0047] The base 110 successively includes from bottom to top: an adhesive layer 113, a structural steel plate 112, and a covering rubber plate 111. The base 110 includes an adhesive layer 113, a structural steel plate 112, and a covering rubber plate. Among them, the adhesive layer 113 firmly bonds the structural steel plate 112 to the surface of the bridge 200 structure. The structural steel plate 112 is an important force-bearing component of the guardrail, enabling the base 110 to have sufficient strength.
[0048] The column 120 is fixed to the structural steel plate 112. The column 120 is fixed to the structural steel plate 112, with higher strength and is not easily damaged.
[0049] The sight shield 140 extends upward beyond the column 120. By setting the sight shield 140 high enough, the view of the bridge opening 201 can be completely blocked, preventing the drivers on the bridge 200 from seeing the opening 201 and causing psychological fear. The height of the sight shield 140 can be set as needed. For example, the height is such that a driver in the cab cannot see over the sight shield 140 to the opening 201, or a driver walking on the bridge surface of the bridge 200 cannot see over the sight shield 140 to the opening 201. This can prevent drivers from developing acrophobia due to seeing the opening 201.
[0050] The energy dissipation component includes an energy dissipation corrugated steel plate 151. The energy dissipation corrugated steel plate 151 can achieve a good energy dissipation and shock absorption effect.
[0051] The energy dissipation component further includes: an energy dissipation rubber rod 152 arranged between two wave crests of the energy dissipation corrugated steel plate 151.
[0052] When a vehicle collides with the guardrail, a large amount of kinetic energy of the vehicle is absorbed by the energy dissipation corrugated steel plate 151 and the energy dissipation rubber rod 152, reducing the impact damage to the column 120 caused by the energy. Meanwhile, the impact force of the vehicle collision is reduced, making the collision more gentle.
[0053] In this embodiment, the energy dissipation component is a combination of an energy dissipation corrugated steel plate 151 and an energy dissipation rubber rod 152. However, the present utility model is not limited thereto, and those skilled in the art can select other existing materials or parts as the energy dissipation component according to needs.
[0054] The temporary anti-collision guardrail 100 at the bridge opening includes a back diagonal brace 130, and the back diagonal brace 130 is connected to the column 120 and the base 110. The column 120 is provided on the first side of the column 120. By providing the back diagonal brace 130, the horizontal resistance of the column 120 is enhanced.
[0055] When using the temporary anti-collision guardrail 100 at the bridge opening, usually the first side faces the opening 201, and the second side faces away from the opening 201. In this way, when a vehicle accidentally hits the second side of the column 120 of the temporary anti-collision guardrail 100 at the bridge opening, the back diagonal brace 130 can give a reverse supporting force to the column 120 on the first side of the column 120, so that the column 120 is not easily bent and deformed due to the impact.
[0056] The material of the back diagonal brace 130 can be, for example, steel such as carbon steel, low alloy steel, martensitic steel, austenite, etc. Optionally, it can also be a material such as aluminum alloy.
[0057] Reinforcing rib plates are provided at the bottom of the column 120. The stability of the column 120 is increased by the reinforcing rib plates.
[0058] The temporary anti-collision guardrail 100 at the bridge opening includes a plurality of columns 120 arranged in a row.
[0059] By providing a plurality of columns 120 to support the sight shielding plate 140 on the first side and the energy dissipation component on the second side. Although a single column 120 can also meet the requirement of supporting the sight shielding plate 140 and the energy dissipation component, usually a plurality of columns 120 are used to support the sight shielding plate 140 and the energy dissipation component.
[0060] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is the orientation of the device or component in normal use, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation at any time. Therefore, it should not be construed as a limitation of the present utility model in this regard.
[0061] Although the specific embodiments of the present utility model have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present utility model is defined by the appended claims. Without departing from the principle and essence of the present utility model, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present utility model.
