Problems solved by technology

The problem with the guardrail of this structure is that each column will protrude above the upper cross bar, which will cause complicated feelings for passers-by and motor vehicle drivers.
[0003] In addition, in order to facilitate the safety of driving at night, it is usually necessary to paste a reflective coating on the guardrail, and the reflective coating of the guardrail of the above structure can only be attached to the vertical pole, which is not conducive to the viewing angle of the motor vehicle driver on the one hand. On the one hand, it also increases the use of reflective coatings

Embodiment 1）

[0018] See Figure 1 to Figure 5 , The streamer guardrail of this embodiment includes an outer column 1 , three guardrail units 2 and four bases 3 .

[0019] The outer column 1 includes a left outer column 1-1 and a right outer column 1-2.

[0020] Each guardrail unit 2 includes an inner column 21 , an upper cross bar 22 , a lower cross bar 23 and thirteen vertical bars 24 .

[0021] The inner column 21 includes a left inner column 21-1 and a right inner column 21-2.

[0022] The tops of the left inner column 21 - 1 and the right inner column 21 - 2 are flush with the tops of the thirteen vertical bars 24 , and are all located below the upper cross bar 22 . The bottom ends of the thirteen vertical bars 24 are located above the lower cross bar 23 , and the bottom ends of the left inner column 21 - 1 and the right inner column 21 - 2 are lower than the bottom ends of the thirteen vertical bars 24 . The lower cross bar 23 is located between the left inner column 21-1 and the r...

Embodiment 2）

[0027] See Image 6 with Figure 7 , this embodiment is basically the same as Embodiment 1, the difference is:

[0028] A reflective coating 25 is pasted on the upper cross bar 22 in each guardrail unit 2 .

[0029] The inner column 21, the upper cross bar 22, the lower cross bar 23 and the vertical bar 24 in each guardrail unit 2 are plug connectors, see the embodiment 2 of CN101265694A for the plug connection method.

Embodiment 3）

[0031] See Figure 8 , this embodiment is basically the same as Embodiment 1, the difference is:

[0032] There are six guardrail units 2 and seven bases 3, and there are six vertical bars on each guardrail unit 2.

Abstract

The invention discloses a streamer guardrail. The streamer guardrail comprises an outer stand column, at least two guardrail units and at least three bases; the outer stand column comprises a left outer stand column and a right outer stand column; each guardrail unit comprises an inner stand column, an upper transverse rod, a lower transverse rod and a vertical rod; the inner stand column comprises a left inner stand column and a right inner stand column; the two inner stand columns in each guardrail unit are respectively arranged at both sides of all vertical rods in each guardrail unit; moreover, top ends of the two inner stand columns are parallel and level to top ends of all vertical rods, and bottom ends of the two inner stand columns are lower than bottom ends of all vertical rods. The streamer guardrail provided by the invention is entirely smooth, and stable visible feelings can be brought about to passersby and drivers of automotive vehicles.

Description

technical field [0001] The invention relates to a guardrail, in particular to a streamer guardrail. Background technique [0002] Guardrails are usually composed of columns, upper rails, lower rails and vertical bars, wherein the upper rails, lower rails and vertical bars constitute a guardrail unit, and in order to ensure the strength of the guardrail unit, the vertical bars of each guardrail unit The number will not be too much, usually within 15, so that when in use, the upper crossbar and lower crossbar of each guardrail unit are installed on both sides of the column through the connecting piece (such as Chinese patent documents CN101265694A, CN202108017U, etc.) , thus forming a row of guardrails. The problem with the guardrail of this structure is that each column will protrude above the upper cross bar, which will cause complicated feelings to passers-by and motor vehicle drivers. [0003] In addition, in order to facilitate the safety of driving at night, it is usua...
