Description

Technical Field

[0001] The utility model relates to the technical field of highway guardrails, in particular to a wave-type integrated highway guardrail. Background Art

[0002] The function of highway safety guardrails is to create a safer, smoother and more civilized traffic order. The cross-section of the safety guardrail is wavy, which helps to improve the impact resistance of the guardrail.

[0003] Traditional guardrails are assembled and fixed to the support components on the outside of the riser by bolts. When impacted, the support components are easily deformed or even detached from the riser, causing the guardrail to separate from the riser and causing a secondary accident. Although the safety guardrail has high impact resistance, the connection strength between the guardrail and the riser is not high, posing a great safety hazard.

[0004] To solve the above problems, we proposed a wave-type integrated highway guardrail. Utility Model Content

The upper end plate of the arc plate 1 and the lower end plate of the arc plate 2 are both provided with notches corresponding to the outer wall of the vertical pipe. The outer wall of the vertical pipe is fixedly sleeved with a positioning plate located on the lower side of the lower end plate of the arc plate 2, and a plug hole is provided on the positioning plate.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 5 A wave-type integrated highway guardrail comprises a guardrail body and two risers 5. The guardrail body comprises an arc plate 1, an arc plate 2, and an arc plate 3. The arc plate 1, the arc plate 2, and the arc plate 3 respectively constitute the upper, lower, and middle parts of the guardrail body. The outer arc surfaces of the arc plate 1 and the arc plate 2 are arranged forward, and the outer arc surfaces of the arc plate 1 and the arc plate 2 are impact surfaces. The outer arc surface of the arc plate 3 is arranged backward. The arc plate 1, the arc plate 2, and the arc plate 3 all comprise upper and lower end plates horizontally connected to their upper and lower ends. The upper and lower end plates of the arc plate 3 are respectively integrated with the lower end plate of the arc plate 1 and the upper end plate of the arc plate 2.

[0022] The upper and lower end plates of the arc plate three 3 are symmetrically provided with sockets 7, which are close to the left and right ends of the arc plate three 3 respectively. Two vertical pipes 5 are vertically inserted into the corresponding sockets 7 respectively, passing through the arc plate three 3. The upper ends of the vertical pipes 5 extend to the rear side of the upper end plate of the arc plate one 1, and the lower ends of the vertical pipes 5 extend to the lower side of the guardrail body. The vertical pipes 5 are fixedly set on the foundation beside the highway to support and fix the guardrail body.

[0023] The upper end plate of the arc plate 1 and the lower end plate of the arc plate 2 are both provided with notches corresponding to the outer wall of the riser 5. The outer wall of the riser 5 is fixedly sleeved with a positioning plate 6 located on the lower side of the lower end plate of the arc plate 2. The positioning plate 6 is horizontally arranged and has a socket 7 on it. The lower end plate of the arc plate 2 is provided with a socket connected to its notch. A bolt 8 is inserted between the socket and the socket 7. A nut 9 located on the upper side of the lower end plate of the arc plate 2 is sleeved on the bolt 8. The lower end plate of the arc plate 2 is fixedly connected to the positioning plate 6 by the fastening connection between the bolt 8 and the nut 9, so that the guardrail body and the riser 5 remain fixed.

[0024] In order to reduce the load-bearing capacity of the positioning plate 6, a supporting mechanism is arranged between the upper end plate of the arc plate 1 and the top end of the vertical pipe 5, and the supporting mechanism includes a plug 10 vertically inserted into the vertical pipe 5, and the upper end of the plug 10 is fixedly connected to a top cover 11 located on the outside of the vertical pipe 5, and a vertical connecting plate 12 is fixedly connected to the top cover 11. The connecting plate 12 is vertically arranged downward and inserted between the vertical pipe 5 and the notch of the upper end plate of the arc plate 1, and the lower end of the connecting plate 12 is fixedly connected to a supporting plate 13 located on the lower side of the upper end plate of the arc plate 1. The supporting plate 13 is horizontally arranged and fits with the upper end plate of the arc plate 1 to support it, so as to share the force of the guardrail body on the positioning plate 6.

[0025] The lower wall of the upper end plate and the upper wall of the lower end plate of the arc plate three 3 are fixedly connected with a baffle 14 located on the front side of the vertical pipe 5. The baffle 14 is used to increase the contact area between the guardrail body and the vertical pipe 5, and reduce the impact deformation of the guardrail body on the vertical pipe 5 after the guardrail body is hit. The through hole 4, the plug hole 7 and the socket are all arranged in a strip shape, so that when the guardrail body is sleeved on the vertical pipe 5, there is a small movement space, which is convenient for the installation and removal of the guardrail body. At the same time, the plug hole 7 and the socket arranged in the strip shape reduce the positioning plate 6 and the arc plate two 2, which is convenient for the installation of the bolt 8 and improves the installation efficiency of the guardrail body and the vertical pipe 5. Since the nut 9 is located on the inner side of the arc plate 2, it is difficult to operate. Therefore, a stopper 15 located on one side of the nut 9 is fixedly provided on the lower end plate of the arc plate 2. The nut 9 is limited by the stopper 15 to prevent it from rotating. The bolt 8 can be directly rotated on the lower side of the guardrail body to tighten the bolt 8 and the nut 9, which further improves the disassembly and assembly efficiency of the guardrail body and the vertical pipe 5.

[0026] In the utility model, the guardrail body is arranged in a wave shape. When the guardrail body is hit, since the guardrail body is directly sleeved on the vertical pipe 5 through the through hole 4 on the guardrail body, the guardrail body is difficult to be separated from the vertical pipe 5, thereby improving the connection strength of the guardrail. In addition, the guardrail body and the vertical pipe 5 are easy to install, which is conducive to the disassembly and assembly of the guardrail.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
