Abstract
The utility model discloses a set of anchor head locking part, the simplest locking part is that the external anchor of form that fills special solid glue by adding in sleeve increases by a heavy locking component; Add a tapped sleeve and be with after externally threaded hollow intermediate plate screw rod in root on this basis, become three lock firmware, form quadruple locking piece if head is set up caltrop again; Be with the externally threaded cored screw of being with of a top wedgewise with the anchor head locking part of spring, intermediate plate be housed in screw rod, by spring top clamping intermediate plate with locking steel strand.The utility model proposes first on steel strand, to set up the mode of locked teleswpe part outside anchor head intermediate plate and strengthens anchor head locking force, make up the technological deficiency of carrying out anchoring locking by single intermediate plate, so not only improve the outer anchor locking force of anchor cable, and guarantee that anchor cable is no longer because of the loosening phenomenon that slip occurs of intermediate plate, avoid, because of the problem that outer anchor head locking is former thereby cause prestress anchorage cable to lose efficacy, significantly promoting durability and the safety of slope anchorage structure.
Description
Technical field
The utility model belongs to anchoring engineering technical field, relates in particular to a kind of anchor head locking part.
Background technology
Aspect prestress anchoraging fixture and anchoring system, the sixties, when China has just started to apply prestress anchorage cable, owing to there is no special anchoring fixture, the outer anchor head of compressor wire mainly adopts reinforced concrete knoll anchor head, and construction is complicated, and prestressing force is difficult for keeping, stretching force is also less, and the anchor clamp of steel strand is long-term dependence on import.In supporting development 6000kN level tensioning equipment, develop specially 6000kN level anchoring facility during the Seventh Five-Year Plan period, comprised moveable anchor, work anchor, the anchoring clamping piece that amount of recovery is little and loss of prestress is little.Now formed the presstressing tendon anchor series of great variety of goods, required precision has all reached international like product level.On probation through development in a few years, before and after 1987, release two kinds of prestress systems of XM and QM.YM and OVM system etc. are developed successfully in succession subsequently, make the prestressed stretch-draw anchor technology of China obtain developing rapidly, and product is constantly perfect, has approached international most advanced level.The anchor clamp that China produces at present mainly contains XM, QM, and OVM, YM, DM, GLM, LM, YFM etc., are widely used in each engineering at home.
At present the anchoring engineering of most domestic all adopts strand tapered anchorage to lock, but has a kind of serious defect near the mode itself that intermediate plate carries out single locking, and intermediate plate outer end is without constraint, thereby makes intermediate plate be easy to occur the phenomenon that comes off, jumps out.Prestress anchorage cable can be subject to the impact of all external environment conditions after being on active service, as produced under the reciprocating of seismic forces, the lasting thrust that comes down, stress is concentrated, rock mass is crept produces stress relaxation etc., under all adverse effects, adopt that single strand tapered anchorage just there will be intermediate plate to break, intermediate plate comes off etc., thereby prestressing force is lost, prestress anchorage cable lost efficacy, and then caused the failure of engineering, even had the danger that leads to Serious geological disasters.
Utility model content
The purpose of this utility model is several anchor head locking parts that propose the technical measures solid for the double relocking at the most of outer anchor enforcement and design thus, is intended to solve the critical defect of current domestic anchor clipper very easily loosening (particularly loosening under the Cyclic Loadings such as earthquake) and the outer anchor Problem of Failure causing thus.
The utility model is achieved in that the mode that a kind of anchor head locking part is set up locked teleswpe part by the outer steel strand of intermediate plate strengthens anchor head locking force, and avoids thus outer anchor because of the loosening phenomenon losing efficacy of intermediate plate.
The simplest anchor head locking part of one, comprises sleeve, anchor adhesive; Outside anchor head intermediate plate, on steel strand, set up a steel bushing, between sleeve and steel strand, leave space, in space, inject high-strength anchor adhesive, by anchor adhesive, sleeve and steel strand bonding are fixed.
A kind of multiple anchor head locking part, comprises the hollow intermediate plate screw rod of band external screw thread, band inner thread sleeve, anchor adhesive, and the caltrop set up of enhanced type anchor head locking part;
Outside anchor head intermediate plate, on steel strand, cover is with externally threaded hollow intermediate plate screw rod, the band hollow intermediate plate screw rod of external screw thread top is three clip type structures, there is a tapped sleeve at the hollow intermediate plate screw jacket of band external screw thread, by sleeve, hollow intermediate plate screw rod is tightened, by intermediate plate locking steel strand; Between the epimere with inner thread sleeve and steel strand, leave space, inject high-strength anchor adhesive by top aperture, steel strand and the anchoring of band inner thread sleeve are integrated.
Further, described multiple anchor head locking part, if add caltrop exposing steel strand part, thrusts between steel strand steel wire, makes steel strand exposed parts expansion chap, stops steel strand retraction, becomes the anchor head locking part of enhanced type.
Further, described multiple anchor head locking part adopts the intermediate plate separate type anchor head locking part with spring, comprises band external screw thread cored screw, band inner thread sleeve, intermediate plate, spring, anchor adhesive;
Outside anchor head intermediate plate, on steel strand, cover is with externally threaded cored screw, band external screw thread cored screw top wedgewise, intermediate plate is equipped with in wedge shape the inside, there is a band inner thread sleeve at band external screw thread cored screw overcoat, add shock mount at band external screw thread cored screw top, by spring top clamping intermediate plate, lock steel strand by intermediate plate; Between band inner thread sleeve epimere and steel strand, leave space, inject high-strength anchor adhesive by top aperture, steel strand and the anchoring of band inner thread sleeve are integrated.
effect gathers
