Abstract
The utility model discloses an anti-corrosion wear-resistant steel strand stay cable. The anti-corrosion wear-resistant steel strand stay cable is characterized in that the steel strand stay cable is located outside a cable bent tower saddle anchorage section, a stay cable section is formed by arranging a PE jacket on a hot galvanized steel strand, and the cable bent tower saddle anchorage section is resistant to corrosion and wear and is formed by arranging a polyurea anti-corrosion wear-resistant face layer on the hot galvanized steel strand. According to the anti-corrosion wear-resistant steel strand stay cable, through the polyurea anti-corrosion wear-resistant face layer, the corrosion resistance, the tenacity, the tensile strength, the impact resistance and the wear resistance of the steel strand stay cable are greatly improved, the steel strand in high-stress-amplitude friction fatigue is protected, the service life of the steel strand stay cable can be effectively prolonged, replacement, maintenance and adjustment of cable force of the stay cable are greatly facilitated, and the construction difficulty is lowered.
Description
Technical field
The utility model relates to the suspension cable being applied in cable stayed bridge, more specifically says a kind of steel strand stay cable at Sarasota saddle anchoring section with anticorrosion antiwear layer.
Background technology
The suspension cable of tradition cable stayed bridge adopts galvanizing without bonding PE sheath steel strand mostly, is the plating zinc on surface at steel strand, steel strand gap perfusion grease, and outsourcing PE sheath forms finished steel twisted wire.But at Sarasota upper saddle seat anchoring section, need to divest PE sheath, in saddle outlet anchor device, pour into dope or epoxy mortar is protected.This method difficulty of construction is large, maintenance detects inconvenience, the anticorrosion time limit is short, and under the state of heavily stressed width, the easy fatigue damage of suspension cable, exists certain hidden danger of quality.
Utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, and a kind of steel strand stay cable that can anticorrosion antiwear is provided, and to reduce difficulty of construction when improving suspension cable application life, maintains easily with Suo Li and adjusts.
The utility model is that technical solution problem adopts following technical scheme:
The utility model can anticorrosion antiwear the design feature of steel strand stay cable be: described steel strand stay cable is to be provided with PE sheath on by hot dip galvanizing steel strand to form drag-line section outside Sarasota saddle anchoring section, is on hot dip galvanizing steel strand, to be provided with polyurea anti-corrosion wear-resistant coat to form anticorrosion antiwear anchoring section in Sarasota saddle anchoring section.
The utility model can anticorrosion antiwear the design feature of steel strand stay cable be also:
Described anticorrosion antiwear anchoring section is that the surface spraying at hot dip galvanizing steel strand is formed with corrosion resistant coating bottom, have on the hot dip galvanizing steel strand of corrosion resistant coating bottom, be positioned between steel strand and form packed layer with anticorrosion abrasion-proof polyurea, described packed layer covers described hot dip galvanizing steel strand completely, and described polyurea anti-corrosion wear-resistant coat is formed on the surface of described packed layer.
Described corrosion resistant coating bottom is to adopt the spraying of dual-component polyurethane corrosion resistant coating to form.
The thickness of described polyurea anti-corrosion wear-resistant coat is 2mm.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model arranges polyurea anti-corrosion wear-resistant coat for suspension cable at Sarasota saddle anchoring section; polyurea anti-corrosion wear-resistant coat has splendid anti-corrosive properties, toughness, hot strength, shock-resistant and abrasion resistance; the steel strand of the tired friction of heavily stressed width have been protected; also solved the Anticorrosion of steel strand, the application life of having improved suspension cable simultaneously.
2, the utility model makes the installation of suspension cable without pour into dope or epoxy mortar in saddle outlet anchor device, greatly easily facilitates replacing, maintenance and the Suo Li of suspension cable to adjust, and greatly reduces difficulty of construction.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is the B-B sectional drawing of Fig. 1;
Number in the figure: 1 steel strand, 2 is PE sheath, 3 polyurea anti-corrosion wear-resistant coats, 4 corrosion resistant coating bottoms, 5 packed layers, 6 saddle anchoring sections.
The specific embodiment
The present embodiment can anticorrosion antiwear the structure of steel strand stay cable be:
As shown in figures 1 and 3, steel strand stay cable is on hot dip galvanizing steel strand 1, to be provided with PE sheath 2 to form drag-line section outside Sarasota saddle anchoring section 6; As depicted in figs. 1 and 2, in Sarasota saddle anchoring section 6, be on hot dip galvanizing steel strand 1, to be provided with polyurea anti-corrosion wear-resistant coat 3 to form anticorrosion antiwear anchoring section.
In concrete enforcement, anticorrosion antiwear anchoring section is that the surface spraying at hot dip galvanizing steel strand is formed with corrosion resistant coating bottom 4, have on the hot dip galvanizing steel strand of corrosion resistant coating bottom, be positioned between steel strand and form packed layer 5 with anticorrosion abrasion-proof polyurea, described packed layer covers described hot dip galvanizing steel strand completely, and described polyurea anti-corrosion wear-resistant coat is formed on the surface of described packed layer; Corrosion resistant coating bottom is to adopt the spraying of dual-component polyurethane corrosion resistant coating to form; The thickness of polyurea anti-corrosion wear-resistant coat is 2mm.
The coating process that in the present embodiment, saddle anchoring section has a steel strand stay cable of anticorrosion antiwear layer carries out as follows:
1, adopt the hot dip galvanizing steel strand that is provided with PE sheath, divest the surperficial PE sheath of the hot dip galvanizing steel strand of Sarasota saddle anchoring section position, with organic solvent, clean the grease in steel strand surface and steel strand gap.
2, at the two polyurethane-modified corrosion resistant coatings of component iron oxide red of hot dip galvanizing steel strand surface spraying, the whole uniform folds in the surface of hot dip galvanizing steel strand are formed to corrosion resistant coating bottom.
The polyurethane-modified anti-corrosion primer of the two component iron oxide reds of bottom adopts pistol spraying application, and spray gun should be perpendicular to the surface of steel strand to be painted, and distance is 0.3m-0.5m, and translational speed is even; Spraying is sequentially first up and then down, works continuously, and the spraying that intersects in length and breadth makes steel strand surface by uniform fold 2 times.
3, after standing eight hours, apply anticorrosion antiwear polyureas and will between the steel strand of hot dip galvanizing steel strand, fill up formation packed layer.
Getting one is with perforated plastic casing to be stuck on steel strand, and can on steel strand, slidably reciprocate, polyureas is poured in plastic casing at the uniform velocity to front slide plastic casing, make polyureas uniform filling in the gap of steel strand, use again sponge roller coating one time, guarantee that steel strand gap filling is full.
4, after one hour, the surface spraying anticorrosion antiwear polyureas at packed layer is isolated from the outside hot dip galvanizing steel strand, should guarantee that anticorrosion antiwear polyurea layer surface smoothing, even thickness are 2mm.
During spraying, take thin time method repeatedly to carry out, the coating thickness of every time is controlled at 0.5mm left and right, and final thickness reaches 2mm ± 0.2mm.
5, standing slaking completes the application of steel strand anticorrosion antiwear layer.
The standing 24-48 hour that maintains the original state, environment temperature is 24 hours the curing time during higher than 20 ℃, and environment temperature is in the time of 5-20 ℃, and the curing time will reach 48 hours, if adopt strand shifter transportation, need to after seven days, can carry out in slaking.
