Embodiment 1

[0031] Figure 1 to Figure 3The high-strength stainless steel road guardrail shown mainly includes a guardrail 1, a column 2, an anti-resistance member 4 and a guardrail connection reinforcement plate 5, and the guardrail 1 is fixedly connected to one side of the column 2 through the guardrail connection reinforcement plate 5 and the anti-resistance member 4 , in the embodiment of the road guardrail installed in the isolation zone, a guardrail board 1 can be respectively arranged on opposite sides of the column 2, and the front of the guardrail board 1 faces the side of the road; each guardrail board 1 and at least two equidistant The uprights 2 are connected, and the adjacent guardrails 1 are lapped end to end, and the lapped parts are connected and fixed by welding or bolt connection. In order to improve the stability of the lap joints, the lapped parts are connected to the reinforcing plate 5 and the anti-blocking parts through the guardrail 4 is connected with column 2. I...

Embodiment 2

[0034] Such as Figure 9 As shown, the column of this embodiment can be buried in the soil foundation or cement roadbed, and the part of the column 2 buried under the soil foundation is welded with a column reinforcement plate 7 made of high-strength stainless steel to further improve the demolition resistance of the column , the plate surface of the column reinforcement plate 7 faces the road and is welded on the back of the column 2, which can increase the resistance of the foundation and make the column 2 difficult to collapse. The column 2 of this embodiment is buried underground and is not easy to corrode, and it is not necessary to use a relatively thick column material to resist corrosion, so it can save materials and reduce costs. All the other features are the same as in Example 1.

Abstract

The invention discloses a high-strength stainless steel road guardrail, and belongs to the technical field of traffic facilities. The high-strength stainless steel road guardrail comprises stand columns and guardrail plates, more than two anti-blocking pieces are fixed on each stand column, and the anti-blocking pieces are fixedly connected with the guardrail plates through guardrail connecting reinforcing plates; each anti-blocking piece comprises two buffer sleeves which are sequentially connected between the corresponding stand column and a guardrail connecting reinforcing plate, and the two buffer sleeves are fixedly connected in the radial direction. An impact contact plane is arranged at the outermost end of the side, facing the road, of each guardrail plate, and the two ends of theimpact contact plane extend to the two ends of the guardrail plate respectively. Guardrail reinforcing ribs are arranged on the sides, deviating from the road, of the guardrail plates, and the guardrail reinforcing ribs, the stand columns, the guardrail plates, the anti-blocking pieces and the guardrail connecting reinforcing plates are all made of high-strength stainless steel materials. The high-strength stainless steel road guardrail solves the problems that an existing road guardrail is not high in strength and corrosion resistance, unstable in structure and poor in buffering performance,cannot provide good protection for drivers and passengers of various vehicle types and is insufficient in safety protection performance.

Description

technical field [0001] The invention relates to the technical field of traffic facilities, in particular to a highway guardrail. Background technique [0002] Highway guardrails are protective devices installed on both sides of the road or on both sides of the central isolation belt to prevent driving vehicles from rushing out of the road. An existing highway guardrail includes a column whose lower end is fixedly connected to the foundation, an anti-resistance member connected to the upper part of the column, and a guardrail plate facing the inner side of the road. Each column is connected to the guardrail plate through a single anti-resistance member with only a first-level buffer structure The adjacent guardrails are connected by bolts, and the guardrails are generally made of Q235 galvanized steel. This kind of highway guardrail has the following disadvantages: 1. The strength of the guardrail is low, and it is easy to deform when it collides; 2. The single-point support...
