Abstract
The utility model relates to a component of the express highway traffic rail; a layer of macromolecule stuff is covered over the surface of the traffic rail component when the component is molded by bending; the macromolecule layer is extruded in a composite way and then covers over the surface of the component; the utility model does not need zincification and can avoid the pollution of the environment by the waste water and gas produced when processing zincification to the steels; meanwhile, since the macromolecule layer covered over the surface of the component is anticorrosion like plastic and rubber, the durability performance of the traffic rail component is strengthened under the natural elements; the work of maintenance is greatly reduced; the component is good for environment-protection. Moreover, the macromolecule layer like plastic and rubber can be made into different colors if necessary, which is beautiful and eye-catching and thus enhancing the functions of the traffic rail; the utility model can replace the prior zincification traffic rail component.
Description
Technical field
The utility model relates to the road guard member that uses on road guard member, the especially speedway that uses on a kind of highway.
Background technology
In the road traffic industry, the crossbeam, column, obstruction block, diaphragm, termination that generally will form guardrail etc. is referred to as the road guard member.At present, no matter be the road guard member that uses on ordinary highway or the speedway, the regulation of the relevant product standard of issuing according to Ministry of Communications, all be by steel plate or band steel through clod wash machine-shaping, one-off hole-piercing is finished.In order to prolong the application life of member, increase its decay resistance, generally all be to adopt in the zinc-plated mode of surface of steel plate.But the durability of galvanized steel member under ambient conditionss such as exposing to the sun and rain of natural conditions is still undesirable, and for preventing its corrosion, after date also needs the galvanized steel member is carried out anticorrosion maintenance when having used one section.Simultaneously, the waste water that produces in the process of the zinc-plated processing of steel, waste gas, quite serious to the pollution of environment.After 2002; China's legal construction paces are obviously accelerated; rules such as " law on prevention and cure of occupational disease ", " the safety in production method " of relevant electroplating industry, " promotion law on cleaner production " and " use poisonous substance operation place labour protection regulations ", the catalogue of technology and product " eliminate outmoded production capacity, " (the 3rd batch), " safety management of dangerous chemical products regulations " are promulgated and enforced in succession; to the electroplating industry of traditional handicraft, formed the regulations of increasingly stringent.Therefore, do not utilize and can progressively substitute the trend that traditional galvanizing production has become industry development the environment-friendly products that environment pollutes.And road guard is because the particularity of use occasion, and making all has higher requirement to the intensity of its surface anticorrosion layer, adhesive power, durability etc. under ambient conditionss such as exposing to the sun and rain of natural conditions, and general corrosion-inhibiting coating is difficult for satisfying its requirement.Thereby up to the present, all road guards remain and adopt zinc-plated member, bring disadvantageous consequence to environmental protection.
The utility model content
Not good in order to overcome existing galvanized steel road guard member antiseptic property, the waste water that produces in the process of its zinc-plated processing, waste gas is to the with serious pollution deficiency of environment, technical problem to be solved in the utility model provide a kind of in antiseptic process non-environmental-pollution and have the road guard member of better Corrosion Protection.
The technical scheme that its technical problem that solves the utility model adopts is: the road guard member of bending process moulding, the surface coverage of its member has polymer material layer, this polymer material layer forms by the mode of compound extruding (coextrusion), thereby forms covering layer fine and close, strong adhesion on the surface of member.
The beneficial effects of the utility model are, owing to adopted the mode of the polymer material layer that forms by the compound mode of extruding in the surface coverage of road guard member, make this material layer different microstructures be arranged with zinc-plated one-tenth and general covering layer, thereby not only densification but also strong adhesion, polymer material layer can increase the decay resistance of road guard member preferably attached to the surface of hardware.This road guard member need not to carry out zinc-plated processing, has avoided the waste water of the zinc-plated processing generation of steel, the pollution that waste gas produces environment effectively; Simultaneously; because polymer material layer such as the plastics and the rubber etc. of the covering on the surface of member have stronger resistance to corrosion; thereby strengthened the endurance quality of road guard member under ambient conditionss such as exposing to the sun and rain of natural conditions; can also reduce its maintenance workload widely, and help environmental protection.In addition, polymer material layer such as plastics can also be made different colors according to different needs with rubber etc., and are not only attractive in appearance but also eye-catching, increased the function of use of road guard.
Description of drawings
Fig. 1 is the cross-sectional view of crossbeam of the present utility model.
Fig. 2 is the cross-sectional view of column of the present utility model.
Fig. 3 is the cross-sectional view of another kind of column of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As Fig. 1, Fig. 2, shown in Figure 3, road guard member of the present utility model as crossbeam 2, column 3 etc., is with steel plate or band steel clod wash machine-shaping, and at the surface coverage polymer material layer 1 of crossbeam 2, column 3 etc.Above-mentioned polymer material layer 1 adopts moderate plastics of intensity and hardness or rubber to form plastic layer or rubber layer usually.The covering method of polymer material layer 1 adopts compound extruding of the prior art (or being called coextrusion) process, adopt compound expressing technique to cover polymer material layer 1, can make that it adheres to more firmly, densification and strong adhesion, thereby also can increase the combining closely of tectal intensity and covering layer and member, firmly and reliably.So-called compound expressing technique is meant when steel plate or band steel be the member of different cross section shape by clod wash machine-shaping, macromolecular materials such as plastics or rubber is extruded and attached to the surface of member.The cross sectional shape of above-mentioned crossbeam 2 is different according to different use occasions, for example: the crossbeam 2 of the guardrail of ordinary highway, greenbelt isolation guardrail etc. can adopt the cross sectional shape of circle, rectangle, the guardrail cross beams 2 that uses on the speedway promptly should adopt the wave beams of wave-like according to related standards, as shown in Figure 1.Same reason, the column 3 of guardrail also can adopt multiple cross sectional shape, and 3 of fence uprights that uses on the speedway should be cylindrical shape or flute profile according to related standards, as Fig. 2, shown in Figure 3.Members such as above-mentioned crossbeam 2, column 3 are assembled, can be formed that corrosion resistance is better, color eye-catching road guard attractive in appearance.
