Description
Technical field
The utility model relates to a kind of civil engineering and structural steelwork anchorage drag-line, and particularly a kind of chill casting extruding anchor formula is put down
Row guy of twisted steel cable.
Background technology
Tradition HiAm anchorage, by parallel steel wire end heading, is anchored on wire sub-panel, the steel wire of wire sub-panel bottom and anchor head
Cone chamber Anchor Agent is filled, and forms the anchorage style that heading combines with bonding.Chill casting anchor cable is turned round by many compressor wires
Strand forms, and internal layer is parallel steel wire, and outer layer is HDPE sheath.Make chill casting anchor head, complex process, steel wire unbalance stress.Due to
HiAm anchorage intensity of steel wire relatively low (mostly being 1570MPa level), major part drag-line needs up to a hundred steel wire twistings to twine to be combined into a whole rope,
Sub-wire, heading are the most troublesome, and time and effort consuming efficiency is low.Require strict isometric blanking, and reality be the most isometric does not accomplishes,
Steel wire unbalance stress so certainly will occur.Heading is disposable, once heading failure, and heading needs to cut material again, and
Cutting material makes again steel wire shorten, and this is an insoluble problem.Anchor cable sheath is the most aging, and steel wire directly glues with outer HDPE sheath
Knot, in use, sheath is by traction force as steel wire, and sheath is under the effect of tension, and pole early produces micro-crack, wind
Rain immerses micro-crack, causes inner wire Accelerated corrosion.In view of bulb-end anchorage disadvantages described above, recently, gradually by guy of twisted steel cable institute
Replacing, guy of twisted steel cable is to be that a unit combines drag-line with strands steel wire (steel strand wires), has clip type anchoring side
Formula, monolithic extruded formula anchorage style.Steel strand wires substitute steel wire bigger breakthrough in manufacture craft, but clip type anchors
Probably its year lose folder for a long time, there is hidden danger；Monolithic extruded formula is limited by radical, when drag-line radical is more, and its manufacturability and reliability
Declining therewith, and the requirement to equipment is high, cost is big.
Summary of the invention
The utility model solves the technical problem that and is: provide a kind of chill casting extruding anchor formula parallel
Guy of twisted steel cable is in order to ensure the anchor structure of steel strand wires uniform force.
Guy of twisted steel cable, is applied to single steel strand extruding anchor in drag-line, compensate for the potential safety hazard of clip type anchoring
Overcome again the limitation of monolithic extruded weak effect.
The utility model is attained in that by the following technical solutions
A kind of chill casting extruding anchor formula parallel steel stranded wire drag-line, comprises the anchoring piece unit at Cable body unit and two ends, institute
Stating cable body unit and include steel strand wires, anticorrosion grease, inner sheath, polyester band, oversheath, steel strand wires are wrapped up by inner sheath, steel strand wires
And anticorrosion grease is filled in the space between inner sheath, form non-bending steel cable.Non-bending steel cable bunchy arranged in parallel, by gathering
Fat band is closely wound, and is molded into oversheath by HDPE outside it, forms cable body.
Described anchoring piece unit include cartridge screws, guard shield, anchor cup, gland, capping, backing-up screw, anti-DNA releaxed circular DNA, nut,
Ball pad, backing plate, extruding anchor, reinforcement, P anchor slab, casing, built-in pipe, Anchor Agent.
Told anchor cup peripheral hardware screw thread, screws with nut, and the inside of anchor cup is pyramidal structure.Anchor cup bottom with protect
Cylinder is threaded, arranges P anchor slab, P anchor slab offers the steel strand wires identical with drag-line cable body radical and passes through hole in anchor cup, strengthens
Muscle is placed in P anchor slab front end, and the quantity of reinforcement is identical with steel strand wires, and the steel strand wires end passing through reinforcement each arranges extruding
Anchor, extruding anchor extruder is extruded bonds the end at steel strand wires.
Further described capping is placed in the extruding anchor upper end after bonding, and gland can be tightened in the inside of anchor cup, act on
Many extruding anchors are extruded pressing neat by capping.Anchor cup passes through backing plate hole, on backing plate, arranges cartridge screws beyond anchor cup diameter, uses
With fixing guard shield, for dustproof anticorrosive.Anti-DNA releaxed circular DNA is provided with harness cord screwed hole, and backing-up screw passes through this hole, peaks at nut end face,
The frictional force held out against between screw increase major thread is come locking.One annular ball pad is set between nut and backing plate, adjusts bias stress.
Have aperture on further described casing, Anchor Agent can be made to be pressed at aperture.Anchor Agent be filled in extruding anchor,
In anchor cup and casing, damper is positioned at built-in pipe rear end, and the downside of backing plate is fixed on, under built-in pipe in the upper end of built-in pipe
End is used for positioning cable body damping equipped with upper damper, is provided with a step outside lower damper, prevents from gliding, with lower built-in pipe
Tail end is connected, and inner chamber is placed on cable body, has outward bucker cover to rise.
The beneficial effects of the utility model are:
Owing to using said structure, being partially formed a little extruding anchor unit in anchoring piece front end, anchoring is reliable, stress
Uniformly, the shortcomings of current anchor cable is efficiently solved.This anchorage style not only makes steel strand wires uniform force, anti-fatigue performance
Superior, and antiseptic property, use the cycle long.Drag-line adapts to multi items specification presstressed reinforcing steel, such as epoxy steel strand wires, zinc-plated
Steel strand wires, ordinary steel twisted wire etc., can further be promoted along with the development of prestressing technique and be developed, and can be preferably
Substitute parallel wire stay, there are all features of parallel wire stay.Make simple than parallel wire stay, decrease large-scale
Equipment consumption.Do not limited by prestressing force radical, can arbitrarily be chosen presstressed reinforcing steel radical according to stress demand, with parallel wire stay
Compare the requirement without hexagon Yu twisting.Rigidity friction is not had, it is to avoid the friction of mutual rigidity is damaged between each presstressed reinforcing steel
Lose and weaken bearing capacity, extend the use cycle.
