Description
Technical field
The utility model relates to a kind of coating structure, is particularly useful for the suspension bridge main rope winding section sealing protection coating structure that use in a kind of bridge guard technology field.
Background technology
Main push-towing rope is the main load-carrying members of suspension bridge, is " lifeline " of suspension bridge, injures the life of suspension bridge the seriously corroded of main push-towing rope steel wire.In case main push-towing rope generation corrosion failure, consequence is hardly imaginable.The security incident that all has the main rope of suspension bridge corrosion to cause both at home and abroad, loss are very heavy.And in general, main push-towing rope can not be changed, even local damage, it also is very difficult repairing.Therefore, the protection main push-towing rope is avoided corrosion, becomes a key issue of the normal operation of suspension bridge.It is the main zone of protection of main push-towing rope that main push-towing rope twines silk section, has crucial effects for the protection effect of whole main push-towing rope.
Chinese invention patent ZL 99119397.0 patent of invention prospectus, disclose a kind of anti-corrosion method of suspension bridge main rope winding section, by lining and outer structure be: metal conditioner, non-vulcanization type rubber non-drying sealing compound layer, winding steel wire or band winding layer, metal conditioner layer, print paint layer of epoxy mica iron, polysulfur type waterproof aquaseal layer, non-yellow stain type polyurethane finish layer.
But in this anti-corrosion method, because the main body sizing material of non-vulcanization type rubber non-drying sealing compound does not contain or only contain the cross-linked network of part, therefore not only its cohesive strength is lower, and easy permeate water steam.And non-vulcanization type sealing compound can not provide one deck complete sealant after twining silk, influenced by variation of long term high temperature degree and fluctuating load, causes seal failure easily, causes the reduction of antiseptic property.
China utility model patent ZL200820050655.X discloses a kind of main push-towing rope and twined silk section external surface safeguard structure (by lining and outer): zinc adds coating; Apply the interior anticorrosive coat that forms with vulcanization type high-performance sealing elastomer; Steel wire or band winding layer; Zinc adds coating; The polyurethane-polyurea sealant layer; And the topping of elastic polyurethane finish paint or elastic silicone finish paint or the formation of elastic fluorocarbon finish paint.Chinese invention patent, application number is 200810190126.4, " sealing corrosion proof protection method of rope-suspension bridge cable system " discloses a kind of suspension bridge cable and twined the method that silk section sealing protection is handled: removed the dirt on zinc-coated steel wire for main surface and carry out the drying processing; Coat with lacquer at main push-towing rope steel wire external surface coated with nano modified epoxy sealing; Apply the vulcanization type silane modified polyether sealant; Twine layer of steel wire or band winding layer; Remove steel wire or the dirt of band twisting surface and the unnecessary sealant of being extruded; At main push-towing rope winding steel wire or strip surface coated with nano modified epoxy sealing lacquer; Apply the vulcanization type silane modified polyether sealant, and shaping is to evenly slick and sly curved surface; Apply high weather-proof and have suitable flexible carbamide paint or a silicon-acrylic coatings.
More than the main push-towing rope mentioned in two patents twine in the silk section sealing protection mode, before twining silk, all use the vulcanization type sealant, and the vulcanization type sealant has been sulfided into elastic body (or partial vulcanization elastomer-forming) before twining silk, do not have flowability, being twined a machine easily when twining the silk construction tears to shreds, cause the destruction that twines a preceding protective coating, influence the sealing protection effect of whole coating.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the prior art, provides a kind of simple in structure, and corrosion resistance is good, the paving steel bridge deck structure of long service life
For achieving the above object, the utility model comprises that the main push-towing rope steel wire is wrapped with the internal layer sealing protection layer of silane modified polyether sealing compound, be with winding layer with flexibility on the internal layer sealing protection layer, with the outer sealing protection layer of silane modified polyether sealant, has the topcoat of flexible polyurethane finish or flexible fluorine carbon finishing paint on the outer sealing protection layer on the flexible band winding layer.
Described internal layer sealing protection layer thickness is 0.5-2.5mm; Described flexible band winding layer is steel wire or steel band; Described outer sealing protection layer thickness is 0.5-2.5mm; Described topcoat thickness is 60-150 μ m.
Beneficial effect is: the utility model uses silane-modified sealing compound as the sealing protection material before twining silk, silane-modified sealing compound is to twine a preceding technology at bridge cable specially to require development, it is bonding in extensive range and sealing effectiveness is excellent, and resistance erosion performance is obvious, so do not need the main push-towing rope steel wire is done too much surfacing, do not need to use corrosion protection priming paint yet; After twining silk, sealant slowly vulcanizes the formation elastic sealed body, can realize the long term seal protective action to main push-towing rope.Sealing protective coating structure is simplified greatly, has reduced working procedure, has reduced lot of materials cost and cost of labor.
