Abstract
The utility model discloses a kind of steel for wire drawing, belong to the technical fields such as bridge, building structure.The anchor head being related in the utility model is made up of the steel wire of stay cable end and the anchorage of fixed steel wire, cup is assembled by upper and lower two parts, the cross section of each section is to have bolt hole on the semicircle that there is projection both sides, the projection of side, and bolt is inserted when assembled and is fixed；There is pin hole on the projection of opposite side.Two parts of cup are reserved with gap in assembly.After perfusion chill casting filler, prestressing force is applied to bolt, makes chill casting filler by lateral pressure, so as to improve anchoring property.The utility model implements simple to operate, and anchoring property is reliable, and low cost has a wide range of application, and is particularly suitable for using in cable-stayed bridge, arched bridge pre-stressed boom and suspension bridge, improves the security of structure.
Description
Technical field
The utility model is related to a kind of steel for wire drawing, belongs to the technical fields such as bridge, building structure.
Background technology
By taking cable-stayed bridge as an example, drag-line is the important component of cable-stayed bridge.And because drag-line and bridge tower and girder are constituted
The change and the change of environment temperature of vehicular load, can significantly affect the stretching force of drag-line on high order redundant structure, bridge
Size.Each drag-line includes cable body and the anchor head at two ends, and cable body bears pulling force, by the anchor head at two ends, pulling force is delivered to
Bridge tower and girder.The connection of steel wire must reliably and endurance in anchor head, and this requires the steel wire in anchor cup to obtain reliably
Anchoring.
At present, considered based on cost and environmental protection, use chill casting filler more filler.Chill casting filler in cup is general by epoxy
Resin, iron sand or steel ball, and additive composition.In the first time stress after irrigating chill casting filler, steel wire will occur one
Fixed sliding, the adhesive property between steel wire and chill casting filler can be by a certain degree of destruction.During one's term of military service, long-term temperature becomes
Under the Fatigue Load of change and vehicle, the performance of chill casting filler can be changed, and the adhesive property between filler and steel wire can be moved back
Change, reduce anchoring security.
The content of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art and problem that there is provided a kind of drag-line
Anchor head.
The utility model provide a kind of steel for wire drawing, be made up of the steel wire and anchorage of stay cable end, anchorage include cup,
Anchor slab, connecting cylinder, caulking gum, closure, baffle plate, chill casting filler, anticorrosive packing, it is characterised in that：Cup is spelled by two parts
Dress is formed, and the cross section of each section, which has for both sides on the semicircle of projection, the projection of side, bolt hole, the projection of opposite side
On have pin hole；Reserving gaps between contact surface when assembled, the fill plug seal material in gap treats that chill casting filling intensity reaches design
It is required that after, the encapsulant in cleaning gap, strongly tightening inside bolt, gap closure, chill casting filler has lateral compression.It is cold
The internal stress that casting filler is obtained can be greatly enhanced the anchoring property to steel wire.
Further, cup is divided into two parts, and a part of side has on 4 projections, projection and had along steel wire axis direction
Pin hole, opposite side has overall projection, and 15 are disposed with thereon in the horizontal bolt hole of cup；Another part sets pin
There are corresponding 3 projections hole side, and opposite side also has 15 corresponding bolts hole horizontal in cup.Side is connected using pin
Connect, side is connected by screw bolts, be easy to first plug pin when mounted, fixed side is easy to connect, is easy to contraposition, and reduce
Finally need to tighten the quantity of bolt, accelerate construction speed.
Further, connecting cylinder is used with cup and is threadedly coupled.
Compared with prior art, the utility model has the advantages that：The cup of non-integral type is easy to casting, makes
It is convenient, reduce cost；The anchoring security of drag-line is considerably improved, so as to improve the security and durability of structure.

The anchorage composition of silk 3 and fixed steel wire 3, anchorage include cup 1, anchor slab 2, connecting cylinder 4, caulking gum 5, closure 6, baffle plate 7,
Chill casting filler 8, anticorrosive packing 9.1 point of cup in the utility model is upper and lower two parts, is referred to as cup piece 11 and lower cup
Piece 21.There is a pin hole 13 having on 4 projections, projection along the axis direction of steel wire 3 the upper side of cup piece 11, and opposite side has overall convex
Block, is disposed with 15 in the horizontal bolt hole 12 of anchor cup thereon；There are 3 pieces of projections the side of lower cup piece 21, inside has pin hole 13, separately
Side also has 15 in the horizontal bolt hole 12 of anchor cup.Pin 14 is first plugged when assembled, the side of fixed cup 1, opposite side is inserted
Enter bolt 10 to fix.The gap of 3 mm wides, the fill plug seal material in the gap are reserved during installation bolt 10 between the contact surface of side
Material.Chill casting filler 8 is irrigated, after its intensity reaches design requirement, the encapsulant in rejecting gap, strength screwing bolts 10,
Close reserved gap.The outside of anchor slab 2 is provided with baffle plate 7, and the end of each stock steel wire 3 is fixed on the outer surface of anchor slab 2.Chill casting
Filler 8 is that anticorrosive packing 9 is filled between epoxy compound, and the through hole hole wall of connecting cylinder 4.One end of connecting cylinder 4 passes through spiral shell
