Abstract
The utility model discloses a high-speed highway guardrail, comprising a column pipe (1) and a guardrail board (2) which is connected to the column pipe. The improvement is that; a rust-proof enamel layer (3) is arranged on the surface of the inner hole and the outer circle of the column pipe(1) and the both sides surface of the guardrail board (2). With above layer, the rust resistance of high speed highway guardrail to the bad climate environment of wind blow, sun burn and sleet is enhanced and the service life is prolonged. By the test, the service life can be prolonged about four times, compared to the prior art.
Description
(1) technical field: the utility model relates to highway edge guardrails of both sides spacer assembly; Be specifically related to a kind of freeway guardrail.
(2) background technology: the guardrail that is built up in both sides, speedway edge in the prior art, normally constitute by the column tube of metal material processing and the guardrail board that connects thereon, owing to month after month be in the adverse circumstances that wind, Exposure to Sunlight, sleet drench throughout the year, very easily corrosion damages, and has seriously influenced its application life.
(3) summary of the invention: the purpose of this utility model is to overcome the deficiency that above-mentioned technology exists, and provides a kind of enhancing anti-corrosion, the freeway guardrail that prolongs its application life.
For achieving the above object, the technical solution of the utility model is achieved in that this freeway guardrail, comprises that column tube and the guardrail board that connects thereon constitute; Its improvement is: on the endoporus and outer round surface of described column tube, and on the both side surface of guardrail board, be provided with the anti-corrosion enamel layer respectively.
The utility model has increased the resistant tarnishing of freeway guardrail in the climatic environment that abominable wind, Exposure to Sunlight, sleet drench by be respectively equipped with enamel layer on column tube and guardrail board easy-to-rust surface, has prolonged its application life; After tested: compare its application life with prior art and improve about three times.
(4) description of drawings: Fig. 1 is the utility model front view;
Fig. 2 has the left view of section for Fig. 1;
(5) specific embodiment: Fig. 1-shown in Figure 2.This freeway guardrail comprises the column tube 1 that is shaped by metal material processing and is connected in the guardrail board 2 that it manages lateral surface.On the endoporus and outer round surface of described column tube 1, and on the both side surface of guardrail board 2, handle the firm closely knit anti-corrosion enamel layer 3 that constitutes by the nanometer enamel technology respectively.Usually selecting the thickness of anti-corrosion enamel layer 3 is 0.1～0.2mm.Described guardrail board 2 adopts corrugated (shown in Figure 2) usually; That its appearance and size adopts is long * wide be 4.32 meters * 0.31 meter; Be connected by bolt, nut 6,7 and column tube 1 respectively at guardrail board 2 two ends; In column tube 1 upper end, sealing is connected with end cap 5.The utility model can connect screw 4 near being provided with on the surface at guardrail board 2 two ends, to realize being convenient to connect the guardrail board 2 that prolongs other according to different designing requirements.During use, usually column tube 1 of the present utility model is fixed in the both sides at speedway edge.
Above-described only is preferred implementation of the present utility model.Should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not the technical characterictic that the process creative work just can be associated; can also make some modification and improvement; these variations obviously all should be considered as equivalent feature, still belong within the protection domain of the utility model patent.
Claims (2)
1, a kind of freeway guardrail comprises column tube (1) and company's guardrail board (2) thereon; It is characterized in that: on the endoporus and outer round surface of described column tube (1), and on the both side surface of guardrail board (2), be provided with anti-corrosion enamel layer (3) respectively.
