Description

Technical Field

[0001] This utility model relates to a road safety barrier, belonging to the field of guardrail technology. Background Technology

[0002] Existing guardrails typically consist of metal posts and concrete bases, secured by inserting the posts into the bases or welding them together. However, this type of structure has the following problems during use: the posts are often fixed to the concrete fence using simple plugging or grouting, resulting in low connection strength. They are prone to loosening or falling off after external impact or prolonged use, leading to a decrease in protective performance. The base is fixed to the ground in a relatively simple way, lacking an effective limiting structure, resulting in insufficient wind and vibration resistance after installation, making it difficult to guarantee safety. Furthermore, the overall weight of concrete fences is relatively large, leading to low installation efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the safety hazards, insufficient connection stability, light weight, and low safety protection efficiency of existing mobile guardrails on the market.

[0004] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution: A road safety barrier is provided, comprising: A cement fence and posts, wherein the cement fence has weight-reducing holes on both side walls and the posts are inserted into the cement fence.

A connecting assembly includes an extending reinforcing bar, a connecting steel plate, and a reinforcing steel plate; the extending reinforcing bar is disposed on the side wall of the column and extends towards one end of the concrete fence; the extending reinforcing bar is connected to the connecting steel plate, and the connecting steel plate and the reinforcing steel plate are connected to the concrete fence by bolts.

[0005] Furthermore, the weight-reducing holes are elliptical in shape and arranged at a 45° angle relative to the vertical direction; wherein, the weight-reducing holes do not penetrate the cement fence, and multiple weight-reducing holes are arranged in a linear array along the length of the cement fence.

[0006] Furthermore, the bottom of the base is provided with four screw limiting holes, and the four screw limiting holes are respectively located at the four corners of the base.

[0007] Furthermore, the base is also provided with a steel bar assembly, which is perpendicular to the column and arranged around the column. The steel reinforcement group includes at least four horizontally arranged steel bars, and the insertion cavity formed by the four horizontally arranged steel bars is inserted into the column.

[0008] Furthermore, the extended reinforcing bars are set to four, and the four extended reinforcing bars are arranged in pairs in the vertical direction, with each pair of extended reinforcing bars connected to a connecting steel plate; the two pairs of extended reinforcing bars are respectively set on both sides of the column.

[0009] Furthermore, the surface of the connecting steel plate is provided with bolt connection holes, the reinforcing steel plate is arranged at an angle, and the surface of the reinforcing steel plate is also provided with bolt connection holes; the reinforcing steel plate is attached to the cement fence and connected to the connecting steel plate through the bolt connection holes.

[0010] Furthermore, the post includes an insertion section and a connecting section, wherein the insertion section is inserted into the concrete fence, and the connecting section is located outside the concrete fence; the connecting section is connected to a guardrail.

[0018] Specifically, the cement fence 1 is a long strip structure and is manufactured by casting. Several weight-reducing holes 11 are provided on both side walls. Based on practical experience, this embodiment provides an elliptical weight-reducing hole 11. Specifically, when the cement fence 1 is subjected to external impact, the stress can be evenly distributed along the edge of the elliptical hole, avoiding structural damage caused by stress concentration. The weight-reducing holes 11 are arranged at a 45° angle relative to the vertical direction, and multiple weight-reducing holes 11 are arranged in a linear array along the length of the cement fence 1. During manufacturing, the weight-reducing holes 11 do not penetrate the entire thickness of the cement fence 1 to ensure the structural strength and stability of the fence.

[0019] The post 2 is inserted into the interior of the cement fence 1 to support and connect the main body of the guardrail 6; wherein, the post 2 includes an insertion section 21 and a connecting section 22, the insertion section 21 is inserted into the inner cavity of the cement fence 1, and the connecting section 22 is exposed on the outside of the cement fence 1 for installing the guardrail 6.

[0023] like Figure 2 As shown, the connecting assembly 4 includes an extending steel bar 41, a connecting steel plate 42, and a reinforcing steel plate 43. The extending steel bar 41 is disposed on the side wall of the column 2 and extends to one end of the cement fence 1. The end of the extending steel bar 41 is welded to the connecting steel plate 42. The connecting steel plate 42 is connected to the reinforcing steel plate 43 by bolts. The reinforcing steel plate 43 is attached to the surface of the cement fence 1, thereby connecting the column 2 and the cement fence 1. In this embodiment, bolt connection holes 44 are provided on the surfaces of the connecting steel plate 42 and the reinforcing steel plate 43 for bolt connection.

[0024] Specifically, the extension steel bar 41 is set as four bars, and the four extension steel bars 41 are arranged in pairs in the vertical direction. Each pair of extension steel bars 41 is connected to a connecting steel plate 42. The two pairs of extension steel bars 41 are distributed on both sides of the column 2, thereby achieving double-sided reinforcement and improving the uniformity and stability of the connection under stress.

[0025] During the installation process, multiple cement fences 1 can be connected end to end. Both ends of each cement fence 1 are set as slopes. The reinforcing steel plate 43 is also arranged at an angle to adapt to the installation surface of the cement fence 1, so that the force direction is more reasonable. The two slopes of adjacent cement fences 1 fit together and are connected by bolts to form a continuous protective structure.
