Abstract
The utility model relates to a corrosion resistant anchor rod for anchorage supporting. The major structure of the corrosion resistant anchor rod comprises a plastically packaged threaded steel anchor rod, a plastically packaged anchor head, a plastically packaged hexagonal connecting sleeve, a plastically packaged slurry stopping tapered plug, a plastically packaged steel base plate, a plastically packaged steel plate protection pad, a plastically packaged hexagonal nut, a threaded hole, a tapered part and a threaded plastic package layer; aiming at the shortcoming of easy corrosion of the anchorage supporting anchor rod, the portions and parts of the anchor rod are covered with a high polymer plastic material and the anchor head is directly made of the high polymer plastic material; the corrosion resistant anchor rod is advanced and reasonable in structural design, the parts of the anchor rod are good in corrosion resistant effect after being plastically packaged, and further are resistant to erosion caused by water, acids, bases and salt materials, the anchor rod is protected through the full length and protected against collision, and also is easy to operate, and the service life of the corrosion resistant anchor is 15 times longer than that in the prior art; the corrosion resistant anchor rod can be used under various rock-soil layer conditions and is a quite ideal corrosion resistant anchor rod for anchorage supporting.
Description
Technical field
The utility model relates to a kind of anticorrosion anchor rod for anchoring support, belongs 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.
Isolation and insulation for anchor pole corrosion-resistant technical measures at present, for example adopt corrosion-resistant steel, zinc-plated on anchor pole, with epoxy resin coating, 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 purpose of this utility model is the deficiency for background technology, adopt high molecule plastic material to be coated the 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
The utility model primary structure 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, are middlely screwed and are fixedly connected by plastic packaging six side's splicing sleeves; Front portion at the first plastic packaging twisted steel anchor rod is plastics anchor head, and screws 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; 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.
Described the first 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 utility model has obvious advance compared with background technology, to have corrosion-prone defect for rock-soil layer anchoring support anchor pole, adopt high molecule plastic material to be coated the 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, can improve 15 times than prior art the application life of anticorrosion anchor rod, this anticorrosion anchor rod can use at multiple severe rock-soil layer, it is the very good anticorrosion anchor rod for anchoring support.
