Abstract
The utility model discloses a road guardrail, which comprises a plurality of stand columns and a base, wherein the stand columns are arranged at intervals and the base is connected with the bottoms of the stand columns. An upper cross beam and a lower cross beam which are manufactured by galvanized pipes are welded between two adjacent stand columns, and a plurality of vertical beams which are arranged at intervals and are manufactured by galvanized pipes are welded between the upper cross beam and the lower cross beam. The cross section of the upper cross beam is of a peach heart shape, the cross section of the lower cross beam is oval, and the cross section of each vertical beam is oblate. The outer surfaces of the stand columns, the upper cross beam, the lower cross beam and the vertical beams are sprayed with polyester powder coatings, and the outer surfaces of the vertical beams are stuck with reflective films. The top of each stand column is provided with a buckling cap. The road guardrail has the advantages of high anti-corrosion capability and good impact resisting performance, the service life is long, and the safety performance is greatly increased.
Description
Technical field
The utility model relates to a kind of road guard.
Background technology
At present, known road guard comprises the column that a plurality of intervals are provided with, and the base that can be connected with ground is equipped with in the bottom of column; Be connected with two crossbeams between the adjacent upright posts, be connected with a plurality of vertical beams that are provided with at interval between two crossbeams, between above-mentioned column and the crossbeam be connected and vertical beam and crossbeam be connected the employing connected structure; Surperficial spray paint at column, crossbeam and vertical beam; But because this road guard long term exposure is on road, being exposed to the sun of the erosion of rainwater and sunlight is prone to make this guardrail corrosion, not only influences the aesthetic property of guardrail; The anti-collision performance of road guard is reduced greatly, increased potential safety hazard.
The utility model content
The technical problem that the utility model will solve provides the road guard that a kind of resistant to rust ability is high, anti-collision performance is good.
For solving the problems of the technologies described above; The road guard that is provided comprises many root posts that are provided with at interval and the base that is connected the column bottom; Its design feature is: be welded with top rail and the lower transverse beam processed by galvanized pipe between the two adjacent upright; Many vertical beams that are welded with setting at interval between the upper and lower crossbeam and process by galvanized pipe; The cross section of said top rail is the cross section ovalize of peach heart shape, lower transverse beam, and the cross section of said vertical beam is oblate, and the external surface of said column, top rail, lower transverse beam and vertical beam all is coated with the polyester powder coating.
After adopting said structure, because between vertical beam and the upper and lower crossbeam and all adopt welded construction between upper and lower crossbeam and the column, and its external surface all sprays the polyester powder coating, thereby the resistant to rust ability strengthens greatly; Because the cross section of top rail is the cross section ovalize of peach heart shape, lower transverse beam, the cross section of vertical beam is oblate, thereby anti-collision performance strengthens greatly.In sum, the utlity model has the advantage that the resistant to rust ability is high, anti-collision performance is good, the utility model long service life, security performance improves greatly.
As the improvement of the utility model, the external surface of said vertical beam also is pasted with reflective membrane, thereby night, reflecting effect was good, had improved the safety of driving at night.
As the further improvement of the utility model, the button cap is equipped with at the top of said column, can prevent that rainwater from getting into column, improved the anti-corrosion ability of column.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional drawing along A-A line among Fig. 1;
Fig. 3 is the sectional drawing along B-B line among Fig. 1.
The specific embodiment
Road guard as shown in Figure 1; It comprises many root posts 1 that are provided with at interval and the base 2 that is connected column 1 bottom, and the structure of base 2 is a prior art, and it is used for and being connected of road ground; Column 1 adopts the heat zinc coating plate rectangular tube to process; Button cap 8 is equipped with at the top of column 1, and button cap 8 adopts square column cap, spraying grey polyester powder coating, adopts riveted structure between button cap 8 and the column 1; The top of column 1 also is pasted with the U.S. that is positioned at button cap 8 belows and produces 3M or the yellow reflective membrane 9 of other import engineering level, plays caution and decoration function night.Be welded with the top rail 3 and lower transverse beam 4 processed by galvanized pipe between the two adjacent upright 1; Be that the top rail 3 and the both ends of lower transverse beam 4 and the medial surface of two columns 1 all adopt carbon-dioxide arc welding full weld technology; Carrying out zinc supplementation after the welding again handles; The cross section of top rail 3 is the cross section ovalize of peach heart shape, lower transverse beam 4, the many vertical beams 5 that are welded with setting at interval between the upper and lower crossbeam and process by galvanized pipe, and the last end face of the both ends up and down of vertical beam 5 and the bottom surface of top rail 3, lower transverse beam 4 adopts carbon-dioxide arc welding full weld technology; Carrying out zinc supplementation after the welding again handles; The cross section of vertical beam is oblate, and the external surface of top rail 3, lower transverse beam 4 and vertical beam 5 all is coated with polyester powder coating 6, and this polyester powder coating 6 adopts the outdoor pure polyester powder material of high-quality to process.The external surface of vertical beam 5 also is pasted with reflective membrane 7, and reflective membrane 7 adopts the U.S. to produce 3M or the green reflective membrane of other import engineering level is pasted.
