Description

A kind of guardrail

Technical field

The utility model relates to a kind of guardrail.

Background technology

Guardrail all is comprised of column, cross tube, sheer pole and montant usually, wherein cross tube, sheer pole and montant consist of a fence unit, and in order to guarantee the intensity of fence unit, the montant quantity of each fence unit can be not too much, usually in 15, so in use, all be that cross tube and the sheer pole with each fence unit is installed in column both sides (such as Chinese patent literature CN101265694A, CN202108017U etc.) by connector, thus shape guardrail in a row.The problem that the guardrail of this structure exists: each column all can be given prominence to above cross tube, causes the sensation of numerous and complicated can for like this passerby and automobile driver.

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

The utility model content

The purpose of this utility model is to address the above problem, and a kind of guardrail is provided.

The technical scheme that realizes the utility model purpose is: a kind of 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 that are fixed together is installed in the same base, and an inner column that is fixed together and the lower end of an outer column also are installed in the 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 utlity model has: (1) the utility model is by having increased inner column in fence unit, and the top of inner column is positioned at the below of cross tube, like this can be so that the height of all guardrails between the outer column be consistent, so that whole guardrail is whole smooth, give passerby and a kind of stably visual experience of automobile driver.(2) guardrail of the present utility model can be arranged on reflecting coating on the cross tube, thereby so that the unremitting continuous distributed of reflecting coating under the irradiation of car light, as the time, extend night like this.Because improve the position that reflecting coating arranges, more be conducive to the visual angle of automobile driver simultaneously.In addition, than being attached on the montant, greatly reduced the consumption of reflecting coating.

The specific embodiment

(embodiment 1)

See Fig. 1 to Fig. 5, the guardrail of 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.

The top of left inside column 21-1 and right inside column 21-2 is concordant with the top of 13 montants 24, and all is 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 then is lower than the bottom of 13 montants 24.23 of sheer poles are between left inside column 21-1 and right inside column 21-2.

Be equipped with two bolts hole on the left inside column 21-1 of each fence unit 2 and right inside column 21-2 and left outside column 1-1, the right outside column 1-2.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).

Be equipped with two installing holes on each base 3, be respectively applied to install and fix the lower end of two inner columns 21 that link together or be used for installing and fixing an inner column 21 linking together and the lower end of an outer column 1.
