Abstract
The invention relates to an anchorage supporting anticorrosion anchor rod which mainly structurally comprises plastic-package threaded steel anchor rod bodies, a plastic anchor head, a plastic-package hexagonal connecting sleeve, a plastic-package grouting stop tapered plug, a plastic-package steel base plate, a plastic-package steel plate protection pad, a plastic-package hexagonal nut, a screw hole, a tapered portion and a threaded plastic-package layer. The anchorage supporting anticorrosion anchor rod has the advantages that the anchorage supporting anticorrosion anchor rod aims to overcome the shortcoming that an existing anchorage supporting anchor rod can be corroded easily, various portions and components of the anchor rod are coated by high-polymer plastic materials, the anchor head is directly made of high-polymer plastic materials, accordingly, the anticorrosion anchor rod is advanced and reasonable in structural design, a good anticorrosion effect can be realized after the various portions and the various components of the anchor rod are packaged by plastics, corrosion due to water, acid, alkali and salt substances can be prevented, the anchor rod can be protected in the full-length direction, is anti-collision and is easy to operate, the service life of the anticorrosion anchor rod can be prolonged by 15 times as compared with the prior art, and the anchorage supporting anticorrosion anchor rod can be used under various rock and soil layer conditions and is perfect.
Description
Technical field
The present invention relates to a kind of anticorrosion anchor rod for anchoring support, belong to the technical field of geotechnical engineering anchoring support equipment and component.
Background technology
Anchor pole is as the support unit of geotechnical engineering, be widely used in building, digging, foundation ditch, tunnel and slope project, by being arranged on the resistance to tension of anchor pole in rock-soil layer, and anchor pole combining closely between injecting cement paste and Rock And Soil around, firm Rock And Soil, the resistance to overturning of raising Rock And Soil.
Because anchor bar body is in Rock And Soil, the moist impact of being seeped water while being particularly arranged in corrosivity stratum is larger, and steel anchor pole corrosivity is strengthened, and the corrosion rate of anchor pole is accelerated, and has had a strong impact on the application life of anchor pole, and even harm is produced and construction safety.
For anchor pole corrosion-resistant technical measures, be isolation and insulation at present, for example adopt corrosion-resistant steel, zinc-plated on anchor pole, with epoxy resin, apply, or on anchor pole, add tubing, but these technical measures are unsatisfactory, antiseptic effect is not good, still have a lot of defects, corrosion resistant low-alloy steel price is more expensive, and zinc coat and other coatings can reduce anchor pole with the adhesion strength between mortar body; Because thickness of coating is generally thinner, anchor pole very easily comes off in transportation, installation process, and the ductility coefficient of these coatings is less, in use, easily cracks, and loses anti-corrosion function; Anticorrosive casing pipe construction is complicated, and corrosive liquids is easily infiltrated in junction, subjects to corrosion.
Summary of the invention
Goal of the invention
The object of the invention is the deficiency for background technology, adopt high molecule plastic material to be coated each portion of anchor pole, anchor head is directly used high molecule plastic material, to increase substantially decay resistance and the antiseptic power of anchor pole, extends the application life of anchor pole.
Technical scheme
Primary structure of the present invention comprises: plastic packaging twisted steel anchor rod, plastics anchor head, plastic packaging six side's splicing sleeves, plastic packaging grouting tapered plug, plastic packaging steel padding, plastic packaging steel plate protection pad, plastic packaging six square nuts, screw, tapered portion, screw thread plastic packaging layer;
The first plastic packaging twisted steel anchor rod, the second plastic packaging twisted steel anchor rod structure are the same, are major axis shape, middlely by plastic packaging six side's splicing sleeves, are screwed and are fixedly connected; Front portion at the first plastic packaging twisted steel anchor rod is plastics anchor head, and screws connection by screw; At the rear portion of the second plastic packaging twisted steel anchor rod, connect plastic packaging grouting tapered plug, at the rear portion of plastic packaging grouting tapered plug, connect plastic packaging steel padding, at the rear portion of plastic packaging steel padding, connect plastic packaging steel plate protection pad; The second plastic packaging twisted steel anchor rod, through plastic packaging grouting tapered plug, plastic packaging steel padding, plastic packaging steel plate protection pad, screws fixing by plastic packaging six square nuts; Section shape of the first plastic packaging twisted steel anchor rod, the second plastic packaging twisted steel anchor rod is the same, and it is coated by screw thread plastic packaging layer that screw thread cuts shape surface.
Described plastics anchor head, front outside is tapered portion, and tapered portion angle is 90 °, and rear inside is for installing connection screw.
The first described plastic packaging twisted steel anchor rod, the second plastic packaging twisted steel anchor rod structure, diameter are identical, and its diameter, length can optionally be added and subtracted, and it is coated by screw thread plastic packaging layer that its screw thread cuts shape surface, and it is square that the screw thread of screw thread plastic packaging layer cuts shape.
Beneficial effect
The present invention compares with background technology has obvious advance, to have corrosion-prone defect for rock-soil layer anchoring support anchor pole, adopt high molecule plastic material to be coated each portion of anchor pole and part, anticorrosion anchor rod external overall is coated by screw thread plastic packaging layer, anchor head is directly used high molecule plastic material, this anticorrosion anchor rod structure design is rationally advanced, after each part plastic packaging, anticorrosion ability is good, waterproof, acid, alkali, salts substances corrodes, elongated protection, anticollision, easy to operate, can improve 15 times than prior art the application life of anticorrosion anchor rod, this anticorrosion anchor rod can be used at multiple severe rock-soil layer, it is the very good anticorrosion anchor rod for anchoring support.
