Description
Technical field
The utility model relates to fastening piece, particularly relates to a kind of anticorrosion anchor bolt for the Oversea wind basis.
Background technique
The life requirements of the anticorrosion protection of steel structure surface of wind power generating set is at least 15 years (abide by the ISO12944-1 standard: surface long term protects), and its anti-corrosion protection target is to reach the lower 30 years life requirements of ocean environment.According to international standard ISO12944-2, be in that the corrosion of steel structure grade is C5-M under the ocean environment.Although anchor bolt is positioned among the parcel of basic concrete stake, owing to contain a large amount of chlorions in seawater or the ooze, it will produce very serious erosion to anchor bolt by the cement space.In a single day the anchor bolt that is positioned among the cement parcel is corroded; there is hardly the possibility of repairing; general people process in order to make metal bolts have better antiseptic effect to carry out Dacroment to it; but; anchor bolt length reaches more than 6 meters; common Dacroment difficult treatment; and common Dacroment contains the chromium element in processing and can cause environmental pollution; this has brought stern challenge to the anti-corrosion protection that is positioned at marine wind power generating set basis anchor bolt; therefore, can under ocean environment, there be the anchor bolt of good antiseptic effect very important for the design of offshore wind turbine foundation anchor bolt is a kind of.
The model utility content
In order to solve deficiency of the prior art, realize and satisfy the anti-corrosion protection life requirements in 30 years of sea climate environment apparatus for lower wind generator set, the utility model has designed a kind of anticorrosion anchor bolt:
Comprise screw rod; described screw rod two ends are equipped with thread section; at least the end at screw rod is provided with the Rustproof cover of protecting nut, pad and can covering the thread section that exposes; it is characterized in that: be provided with the chromium-free Dyclo coating at screw rod, nut and gasket surface, be provided with the epoxy glass flake coating in the chromium-free Dyclo coating of screw rod.
On screw rod, also be arranged with the with it anticorrosive casing pipe of external diameter coupling.
Described sleeve pipe two ends and crab-bolt bolt attachment portion seal with heat-shrinkable T bush.
The material of described Rustproof cover is silicone rubber.
The material of described sleeve pipe is PVC.
Be coated with the epoxy zinc rich primer that plays shielding and cathodic protection effect at the thread section that is provided with Rustproof cover one end, pad and nut.
The chromium-free Dyclo coating thickness is the 10.0-11.9 micron.
Epoxy glass flake coating dry film thickness is the 50-80 micron.
Whole (containing nut, the pad) chromium-free Dyclo of bolt is processed, compared with common Dacromet Technology, chromium-free Dyclo does not contain chromium ion, environmentally safe, harmless, and need not to be heating and curing, energy saving, simultaneously easy construction on anchor bolt, effective.Part between the thread section on the screw rod added again be coated with the epoxy glass flake coating, this coating provides good shielding properties, can effectively completely cut off the erosion of the aggressive mediums such as chlorion.
Sheathed corrosion-resistant sleeve pipe on screw rod; the Rustproof cover of the thread section that is provided with protection nut, pad in the screw rod end and exposes; and apply the epoxy zinc rich primer that plays shielding and cathodic protection effect at nut, pad and the thread section place of exposing, can more effectively prevent the erosion of seawater.
Description of drawings
Fig. 1 is anticorrosion anchor bolt structural representation.
Fig. 2 is that anticorrosion anchor bolt connects the partial structurtes schematic representation that is connected with offshore wind power foundation concrete and flange.
Embodiment
Anchor bolt schematic representation as shown in Figure 1, shown in anchor bolt comprise screw rod 1, be equipped with thread section 2 at the two ends of screw rod 1, be connected with nut 3 at thread section 2, also be provided with pad 4 on the thread section 2.Bolt whole (containing nut and pad) adopts environment-friendly chromium-free Dacroment (being Aluminum Coating) to process, make the bolt integral surface be provided with chromium-free Dyclo coating 6, the thickness of chromium-free Dyclo coating 6 is the 10.0-11.9 micron, then be provided with epoxy glass flake coating 7 on screw rod 1 chromium-free Dyclo coating 6, the thickness of epoxy glass flake coating 7 is the 50-80 micron again.After above-mentioned processing, be arranged with corrosion-resistant sleeve pipe 8 at screw rod 1, sleeve pipe 8 length are determined according to screw rod 1 design length of bolt, the sheathed upper heat-shrink tube of the both ends open of sleeve pipe 8, heat hot draw heat-shrink tube begins to shrink, wrap sleeve pipe 8 and screw rod 1, thereby sleeve pipe 8 be sealably coupled on the anchor bolt, above the material of the sleeve pipe 8 mentioned be PVC.
The partial structurtes schematic representation that is connected with offshore wind power foundation concrete and flange of anchor bolt as shown in Figure 2, comprise anchor bolt, and concrete 10 and flange plate 9, exposed parts adopted corrosion-resistant Rustproof cover 5 to protect after anchor bolt was connected with flange plate 9, and Rustproof cover 5 exposes size according to bolt to be made.Before Rustproof cover 5 is installed; need pad 4, the nut 3 at bolt two ends and the helical thread portion 2 coating epoxy zinc rich primers that expose are protected; require Rustproof cover 5 bottoms and bolt fitting surface good leak tightness after the installation, can effectively prevent the contact bolt and nuts 3 such as steam, dust.Can only install at exposed parts when Rustproof cover 5 is installed, and the part that is embedded in the concrete does not need to install, also can nut end be installed by Rustproof cover 5 in being embedded in concrete in order to reach better effect, described Rustproof cover 5 materials are silicone rubber.
