Abstract
The invention discloses a kind of steel for wire drawing and preparation method thereof, belong to the technical fields such as bridge, building structure.Anchor head involved in the present invention is made of the steel wire of stay cable end and the anchorage of fixed steel wire, the cup body of anchorage is assembled by upper and lower two parts, the cross section of each section is the semicircle that there are convex block in both sides, has bolt hole on the convex block of side, has pin hole on the convex block of the other side.Two parts of cup body are reserved in assembly and are had the gap.After chill casting filler is perfused, prestressing force is applied to bolt, makes chill casting filler by lateral pressure, to improve anchoring property.Present invention implementation is easy to operate, and anchoring property is reliable, and low cost has a wide range of application, and particularly suitable for being used in cable-stayed bridge, arched bridge pre-stressed boom and suspension bridge, improves the safety of structure.
Description
Technical field
The present invention relates to a kind of steel for wire drawing and preparation method thereof, belong 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 since drag-line and bridge tower and girder form
High order redundant structure, the variation of vehicular load and the change of environment temperature on bridge, can significantly affect the stretching force of drag-line
Size.Each drag-line includes cable body and the anchor head at both ends, and cable body bears pulling force, and by the anchor head at both ends, pulling force is transmitted to
Bridge tower and girder.In anchor head the connection of steel wire must reliable and endurance, this requires the steel wires in anchor cup must obtain reliably
Anchoring.
Currently, being considered based on cost and environmental protection, filler mostly uses chill casting filler.Chill casting filler in cup body is generally by epoxy
Resin, iron sand or steel ball and additive composition.In the first time stress after chill casting filler is perfused, steel wire will occur one
Fixed sliding, the adhesive property between steel wire and chill casting filler can be by a 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 change, and the adhesive property between filler and steel wire can move back
Change, reduces anchoring safety.
Invention content
It is an object of the invention to solve the problems, such as above-mentioned the deficiencies in the prior art and, provide a kind of steel for wire drawing
And preparation method thereof.
A kind of steel for wire drawing provided by the invention is made of the steel wire and anchorage of stay cable end, and anchorage includes cup body, anchor
Plate, connecting cylinder, caulking gum, sealing cover, baffle, chill casting filler, anticorrosive packing, connecting cylinder are used with cup body and are threadedly coupled,
It is characterized in that：Cup body is assembled by two cup pieces, and the cross section of cup piece is the semicircle that there are convex block in both sides, on the convex block of side
There is bolt hole, has pin hole on the convex block of the other side, there is lateral compression inside chill casting filler.Lateral pressure inside chill casting filler
Stress can greatly enhance the anchoring property of steel wire.
A kind of production method of steel for wire drawing provided by the invention makes the simultaneously described each component of anchorage, in assembled cup body
When, pin is respectively adopted and is bolted corresponding two cup pieces, reserving gaps between the contact surface of bolt side are filled out in gap
Sealing material is filled in, chill casting filler is perfused, after chill casting filling intensity reaches design requirement, clears up the sealing material in gap, by force
Power tightens bolt, and gap is made to be closed, and subsequent fabrication process is completed using conventional anchor head production method.To make in chill casting filler
There is lateral compression in portion.
Further, a cup piece of the anchor head is known as upper cup piece, and there are 4 convex blocks in one side, have along steel wire on convex block
There are whole convex block in the pin hole of axis direction, the other side, are disposed with 15 bolts hole in cup body transverse direction thereon；Another cup
Piece is correspondingly known as lower cup piece, and pin hole side has corresponding 3 convex blocks, the other side also to have 15 bolts in cup body transverse direction
Hole.Side is connected using pin, and side is connected by screw bolts, convenient for first plugging pin, fixed side, connection side when mounted
Just, it is convenient for contraposition, and reduces and finally need to tighten the quantity of bolt, accelerates construction speed.
Compared with prior art, the invention has the advantages that：The cup body of non-integral type is convenient for manufacture, making side
Just, cost is reduced；The anchoring safety for considerably improving drag-line, to improve safety and the durability of structure.
