Abstract
The utility model relates to an anti-corrosion bridge bearing seat with an anti-corrosion composite layer. The aim of the utility model is to overcome the defect of the poor anti-corrosion performance of the existing bridge components, and the utility model is suitable for the corrosion of a marine atmospheric environment. The anti-corrosion composite layer is formed by connecting a weathering steel layer (1), a metal spraying layer (2) and a heavy anti-corrosion coating layer (3) in an outward direction from a metal component in a composite way orderly. The metal spraying layer of the utility model has the performance of strongly resisting the corrosion of marine atmosphere, the coating is convenient, and the anti-corrosion composite layer satisfies the anti-corrosion requirement of the bearing seat.
Description
Technical field
The utility model relates to a kind of anticorrosion bridge member, especially a kind of anticorrosion bridge pad that is applicable to naval air environment.
Background technology
The corrosion of bridge steel structural unit is the principal element that influences bridge pad and bridge application life.Therefore adopting the steel member with anticorrosion composite bed is that the opposing burn into prolongs the bridge pad the most direct effective way in application life.
The layer structure of the anticorrosion composite bed steel member that generally adopts in the present bridge pad both domestic and external is " ordinary carbon steel+general overcoat ", and general overcoat is common paint.We find the defective and the drawback of its existence in long-term test and use: anticorrosion period of validity is short, antiseptic effect is undesirable, effectively do not prolonged the application life of bridge pad, more not competent special media corrosive environment is as the requirement for anticorrosion of bridge pad under chemical industry corrosive environment and the marine salt mist corrosion environment.
Summary of the invention
The utility model is intended to overcome the anticorrosion ineffective defective of above-mentioned existing bridge member, a kind of anticorrosion bridge pad with anticorrosion composite bed is provided, in the hope of opposing atmospheric environment corrosion year in year out, especially naval air environment corrosion, prolong the application life of bridge, and do not produce anticorrosion surplus again, economical and practical.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of anticorrosion bridge pad that is applicable to naval air environment, its metal component surface has anticorrosion composite bed, it is characterized in that: described anticorrosion composite bed from hardware outwards successively by weathering steel layer, sprayed metal coating, the heavy anti-corrosion paint layer is compound is formed by connecting.
Weathering steel layer described in the utility model is marine atmosphere corrosion-resisting steel layer or weather resisting steel layer.
Sprayed metal coating described in the utility model is electric arc spraying layer or flame spray coating.
The utility model heavy anti-corrosion paint layer comprises epoxy zinc rich primer layer, thick coated type epoxy enamelled coating, polyurethane finish layer.
The utility model heavy anti-corrosion paint layer comprises epoxy enamelled coating, polyurethane finish layer.
The beneficial effects of the utility model show:
One, the bridge pad antisepsis length of holding time is durable in use, has prolonged bridge effectively
The application life of beam;
Two, has the corrosion resistance that is suitable for particular surroundings;
Three, anticorrosion composite bed application is convenient, is convenient to make;
Four, this bridge pad had both satisfied requirement for anticorrosion, had guaranteed the application life of bearing, again
Anticorrosion surplus can not occur, cause the waste on the resource;
Five, economical, reliable, practical, be a kind of desirable anticorrosion bridge pad.
Description of drawings Fig. 1 is the layer structure schematic diagram of the anticorrosion composite bed of the utility model bearing
The specific embodiment
For guaranteeing bearing function of use and life-span needs, consider reliability and economy designing requirement again, the metal component surface of bridge pad adopts by weathering steel layer, sprayed metal coating, the compound anticorrosion straticulate structure that is formed by connecting of heavy anti-corrosion paint layer.
1, weathering steel layer: at marine atmosphere and splash zone corrosion environment, consider the physical and mechanical properties, processing request of material, make every effort to best economic benefit and social benefit simultaneously, selected the WNH400 marine atmosphere corrosion-resisting steel of not only cheap but also ability sea atmosphere corrosion and atmospheric corrosion for use, or the CortenA weather resisting steel.
2, sprayed metal coating: can be on various solid engineering materials surface, the composite material that sprays various metals and alloy, engineering ceramics, engineering plastics and form by above material, and can form firm setting course, thereby make product surface obtain specific functions such as wear-resisting, anti-corrosion, high temperature resistant, anti-oxidant, low friction, anti-gummed, sealing.The utility model is selected electric arc spray LF for use
2Almag sprayed coating structure, or, also can adopt oxy-acetylene subsonic speed flame spray coating structure according to the requirement for anticorrosion of anticorrosion bearing and the performance and the characteristics of metal spraying.
3, heavy anti-corrosion paint layer: the different time at bearing uses, adopt different application layers.
(1), delivery initial stage application layer structure:
Epoxy zinc rich primer layer SD ZINC 500 (60 μ m)+thick coated type epoxy enamelled coating
EPOMARINE EX-600 (160 μ m)+polyurethane finish layer RETAN6000 (60
μm)。Reach 12～15 years its application life.
(2), maintenance stage application layer structure:
Epoxy enamelled coating NU FORTE (200 μ m)+polyurethane finish layer RETAN6000 (60
μm)。Be not less than its application life 5 years.
The utility model sprayed metal coating has strong anti-sea atmosphere corrosion performance, and application is convenient; This anticorrosion composite bed had both satisfied the requirement for anticorrosion of bearing, had guaranteed the application life of bearing, anticorrosion surplus can not occur again, caused the waste on the resource.
The utility model economy, reliable, practical is a kind of desirable anticorrosion bridge pad.
In addition, the anticorrosion composite bed assembling structure that the utility model adopted is useful for bridge pad other bridge members in addition equally, and the other field metal product.
