The utility model is provided with a corrosion-proof system which has a combined cathode protecting function which can be monitored, adjusted and controlled and a combined shielding protecting function; the corrosion-proof system can prevent the cable from being corroded for a long time in various moisture natural environments; when the cable encounters fires, compositions in the protecting layer can be fast expanded forming a firm thermal insulating layer with high efficiency causing the fire endurance of the cable to reach more than 2 hours. The utility model is suitable for various heavy sections structures has a need of corrosion prevention for a long time or a need of simultaneous corrosion prevention and fire prevention, such as being used as required stay cables or suspension cables and other cables for making various large bridges, heavy sections structure buildings, airport facilities, sports halls, exhibition halls and other heavy sections structure buildings.
Description
Technical field
The utility model relates to a kind of cable with overcoat, this overcoat all has the long life anti corrosion function to various forms of steel cables or has anticorrosion and the fire prevention dual-use function, the cable of making by the utility model is applicable to various large-scale steel structure buildings, cables such as suspension cable that large-scale steel structure buildings such as for example various large bridges and airport installation, gymnasium, exhibition center are required or suspension cable avoid steel building because of the security incident of corroding or fire causes.
Background technology
Development along with modern building cause, the suspension cable that suspension cable that is formed by the steel wire that kinks and parallel wire unit are formed has obtained using widely in numerous modern bridges and steel building, and the anticorrosion of cable and fire prevention become the safety that influences bridge and building and service life one a very important techniques difficult problem.Because the particularity of line structure; be difficult to adopt conventional anticorrosive coating or fireproof paint to protect; the PE resin that existing cable is most to be adopted the PE resin or be added with fire retardant is as protective layer; the PE protective layer is because of aging in long-term use; or fine gap appears in other reasons unavoidably; moisture or corrosive medium are easy to infiltrate; particularly at the easier infiltration corrosive medium of the seam crossing of ground tackle; make steel wire corrosion and cable forfeiture mechanical strength and rupturing; cause major accident; also can only self play fire retardation though added fire retardant to the PE protective layer; it does not possess effect of heat insulation; therefore the steel cables back intensity decreases of being heated causes building collapse during breaking out of fire, can not effectively prevent to corrode or destruction that fire causes, to the security of steel construction with cause service life and have a strong impact on.
Summary of the invention
The purpose of this utility model is exactly to solve above-mentioned technical barrier, seeks a kind of characteristics that can adapt to cable fully, has the technical scheme of anticorrosion and fire prevention dual-use function simultaneously, and this technical scheme must possess following three characteristics:
One, because cable belongs to flexible construction material, therefore anticorrosion and the fire proofing material that matches with it also must be flexible, can be attached to the cable surface for a long time securely.
Two, in the projected life of steel construction, can keep reliable anticorrosion and flameproof effect for a long time.
Protective layer can expand rapidly when three, meeting fire, forms the abundant firm fire proof heat-insulation layer of one deck, and fire endurance can satisfy the fire-fighting requirement.
Have now found that the corrosion proof function that having of a kind of flexibility is fabulous or have anticorrosion simultaneously and the composition of fire prevention dual-use function; it is clamp-oned it in external protection of cable with extruding or additive method; make it be coated on the appearance of cable steel wire; and in the gap of steel wire and steel wire, infiltrate anticorrosive composite (9), just can reach the purpose of this utility model.This anticorrosion fire retardant composition is to have the electrolyte ion conducting, and iron and steel is had the composition of fabulous corrosion inhibitive function, can increase substantially the anticorrosion life-span of cable, and said composition also has the fire of the chance formation fire proof heat-insulation layer that can expand simultaneously.Being burnt when soft when cable during breaking out of fire by PE or by the external protection that other resin is made; the fire retardant anticorrosion composition (2) of the inside just begins to expand; after the external protection scaling loss is broken and is come off; said composition continues to expand and forms the abundant firm fire proof heat-insulation layer of one deck, and fire endurance can reach more than 2 hours.
