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 combining closely around anchor pole between injecting cement paste and Rock And Soil, firm Rock And Soil, improves the resistance to overturning of Rock And Soil.
Because anchor bar body is in Rock And Soil, comparatively large by the impact that infiltration is moist when being particularly arranged in corrosive formation, 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.
Current is isolation and insulation for anchor pole corrosion-resistant technical measures, such as adopt corrosion-resistant steel, zinc-plated on anchor pole, with epoxy resin coating, or add tubing on anchor pole, but these technical measures are unsatisfactory, antiseptic effect is not good, still there is a lot of defect, corrosion resistant low-alloy steel price is more expensive, and zinc coat and other coatings can reduce anchor pole with the adhesion strength between body; Because thickness of coating is general thinner, anchor pole very easily comes off in transport, installation process, and the ductility coefficient of these coatings is less, easily cracks in using, 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 carry out coated to each portion of anchor pole, anchor head directly uses 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 splicing sleeve, plastic packaging grouting tapered plug, plastic packaging steel padding, plastic packaging steel plate protection pad, plastic packaging six square nut, screw, tapered portion, screw thread plastic packaging layer;
First plastic packaging twisted steel anchor rod, the second plastic packaging twisted steel anchor rod structure are the same, are major axis shape, and middle being screwed by plastic packaging six side splicing sleeve is fixedly connected; Be plastics anchor head in the front portion of the first plastic packaging twisted steel anchor rod, and screw connection by screw; Connect plastic packaging grouting tapered plug at the rear portion of the second plastic packaging twisted steel anchor rod, connect plastic packaging steel padding at the rear portion of plastic packaging grouting tapered plug, connect plastic packaging steel plate protection pad at the rear portion of plastic packaging steel padding; 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 nut; 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 has obvious advance compared with background technology, there is corrosion-prone defect for rock-soil layer anchoring support anchor pole, high molecule plastic material is adopted to carry out coated to each portion of anchor pole and part, anticorrosion anchor rod external overall is coated by screw thread plastic packaging layer, anchor head directly uses high molecule plastic material, this anticorrosion anchor rod structure design is rationally advanced, after each portion part plastic packaging, anticorrosion ability is good, waterproof, acid, alkali, salts substances corrodes, elongated protection, anticollision, easy to operate, the application life of anticorrosion anchor rod can improve 15 times than prior art, this anticorrosion anchor rod can use at multiple severe rock-soil layer, it is the very good anticorrosion anchor rod for anchoring support.
