Description

Streamer guardrail

Technical field

The present invention relates to a kind of guardrail, be specifically related to a kind of streamer guardrail.

Background technology

Guardrail is all made up of column, cross tube, sheer pole and montant usually, wherein cross tube, sheer pole and montant form a fence unit, and in order to ensure the intensity of fence unit, the montant quantity of each fence unit can not be too much, usually within 15, so in use, be all that the cross tube of each fence unit and sheer pole are arranged on column both sides (as Chinese patent literature CN101265694A, CN202108017U etc.) by connector, thus shape guardrail in a row.The guardrail Problems existing of this structure: each column all can be given prominence to above cross tube, causes the sensation of numerous and complicated can to like this passerby and automobile driver.

In addition, for the ease of driving at night safety, usually need to post reflecting coating on guardrail, and the reflecting coating of the guardrail of said structure all can only be attached on montant, such one side is unfavorable for the visual angle of automobile driver, too increases the use amount of reflecting coating on the other hand.

Summary of the invention

The object of the invention is to solve the problem, a kind of streamer guardrail is provided.

The technical scheme realizing the object of the invention is: a kind of streamer guardrail, comprises outer column, at least two fence units and at least three bases.Described outer column comprises left outside column and right outside column.Each fence unit comprises inner column, cross tube, sheer pole and montant.Inner column comprises left inside column and right inside column.Two inner columns in each fence unit lay respectively at the both sides of all montants in each fence unit, and the top of two inner columns is concordant with the top of all montants, and the bottom of two inner columns is lower than the bottom of all montants.The left inside column of the fence unit that described left outside column is adjacent is bolted to connection, and the left inside column of the fence unit that the right inside column of each fence unit is adjacent is bolted to connection; The right inside column of the fence unit that described right outside column is adjacent is fixedly connected with.The lower end of two inner columns be fixed together is arranged in same base, and the inner column be fixed together and the lower end of an outer column are also arranged in same base.

Cross tube in each fence unit is provided with reflecting coating.

Inner column in each fence unit, cross tube, sheer pole and montant are single piece or plug connector or shackle member.

The good effect that the present invention has: (1) the present invention by adding inner column in fence unit, and the top of inner column is positioned at the below of cross tube, the height of all guardrails between outer column can be made so consistent, make whole guardrail overall smooth, to passerby and a kind of visual experience stably of automobile driver.(2) reflecting coating can be arranged on cross tube by streamer guardrail of the present invention, thus makes the unremitting continuous distributed of reflecting coating, and such night extends under the irradiation of car light as streamer.The position simultaneously arranged due to reflecting coating is improved, advantageously in the visual angle of automobile driver.In addition, compared to being attached on montant, the consumption of reflecting coating is greatly reduced.

Detailed description of the invention

(embodiment 1)

See Fig. 1 to Fig. 5, the streamer guardrail of the present embodiment comprises outer column 1, three fence units 2 and four bases 3.

Outer column 1 comprises left outside column 1-1 and right outside column 1-2.

Each fence unit 2 comprises inner column 21, cross tube 22, sheer pole 23 and 13 montants 24.

Inner column 21 comprises left inside column 21-1 and right inside column 21-2.

Left inside column 21-1 is concordant with the top of 13 montants 24 with the top of right inside column 21-2, and is all positioned at the below of cross tube 22.The bottom of 13 montants 24 is positioned at the top of sheer pole 23, and the bottom of left inside column 21-1 and right inside column 21-2 is then lower than the bottom of 13 montants 24.Sheer pole 23 is between left inside column 21-1 and right inside column 21-2.

The left inside column 21-1 of each fence unit 2 and right inside column 21-2 and left outside column 1-1, right outside column 1-2 are equipped with two bolts hole.The left inside column 21-1 of the fence unit 2 that left outside column 1-1 is adjacent is fixedly connected with (see figure 3) by bolt 4, and the left inside column 21-1 of the fence unit 2 that the right inside column 21-2 of each fence unit 2 is adjacent is fixedly connected with (see figure 4) by bolt 4; The right inside column 21-2 of the fence unit 2 that right outside column 1-2 is adjacent is fixedly connected with (see figure 5).

Each base 3 being equipped with two installing holes, being respectively used to the lower end of two inner columns 21 be fixed together or the lower end for installing an inner column 21 and outer column 1 be fixed together are installed.

The inner column 21 of the present embodiment, cross tube 22, sheer pole 23 and montant are single piece, and this unitarily formed manufacture method is substantially identical with the embodiment 1 of CN101265694A.And also corresponding with the embodiment 1 of the CN101265694A parts of the shape and structure of the cross tube 22 of the present embodiment, sheer pole 23, montant 24 and base 3 are identical.And the outer column 1 of the present embodiment is identical with the column of the embodiment 1 of CN101265694A, the shape of inner column 21 and the shape of montant 24 similar.
