Abstract
The utility model discloses a kind of parallel wire stay anchor head, belong to the 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, and anchorage includes cup, anchor slab, connecting cylinder, caulking gum, closure, baffle plate, chill casting filler, anticorrosive packing.Cup is assembled by two parts, and the cross section of each section, which has for both sides on the semicircle of projection, projection, reserved bolt hole, and bolt is inserted when assembled and is fixed, reserving gaps between contact surface.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 parallel wire stay anchor head, 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, chill casting filler is used the filler of anchoring steel wire more in anchor cup.It is cold in cup
Cast filler general by epoxy resin, iron sand or steel ball, and additive composition.First time stress after perfusion chill casting filler
When, certain sliding will occur for steel wire, and the adhesive property between steel wire and chill casting filler can be by a certain degree of destruction.It is on active service
Under period, long-term temperature change and the Fatigue Load of vehicle, the performance of chill casting filler can change, filler and steel wire
Between adhesive property can degenerate, 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 there is provided one kind is parallel with problem
Wire digging line anchor head.
A kind of parallel wire stay anchor head that the utility model is provided, is made up of, anchorage the steel wire and anchorage of stay cable end
Including cup, anchor slab, connecting cylinder, caulking gum, closure, baffle plate, chill casting filler, anticorrosive packing, it is characterised in that：Cup by
Two parts are assembled, and the cross section of each section, which has for both sides on the semicircle of projection, projection, reserved bolt hole；It is assembled
When insertion bolt fix, reserving gaps between contact surface, the fill plug seal material in gap, treat chill casting filling intensity reach design will
After asking, the encapsulant in cleaning gap strongly tightens bolt, gap closure.Have inside chill casting filler by applying to bolt
Lateral compression obtained from prestressing force.The internal stress that chill casting filler is obtained can be greatly enhanced the anchoring property to steel wire.
Further, connecting cylinder is used with cup and is threadedly coupled.
Further, two parts of cup are contacted using corresponding teeth groove.This connected mode is easy to two of cup
/ positioning and connection.
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.
Brief description of the drawings
The structure chart of Fig. 1 parallel wire stay anchor heads.
The cross-sectional view of parallel wire stay anchor head in Fig. 2 embodiments one.
The cross-sectional view of parallel wire stay anchor head in Fig. 3 embodiments two.
Identified in figure：1- cups, 2- anchor slabs, 3- steel wires, 4- connecting cylinders, 5- caulking gums, 6- closures, 7- baffle plates, 8-
Chill casting filler, 9- anticorrosive packings, 10- bolts, 11- glasss of pieces.
Embodiment
The technical solution of the utility model is retouched the following is specific embodiment of the utility model, and with reference to accompanying drawing
State, but the utility model is not limited to these embodiments.
Embodiment one
The corresponding schematic diagram of the present embodiment is shown in Fig. 1 and Fig. 2.The anchor head being related in the present embodiment is by steel wire 3 and fixed steel wire 3
Anchorage composition, anchorage include cup 1, anchor slab 2, connecting cylinder 4, caulking gum 5, closure 6, baffle plate 7, chill casting filler 8, anti-corrosion
Filler 9.The cup 1 that the present embodiment is provided is made up of corresponding two cup pieces 11, and there is projection the cross section of cup piece 11 for both sides
There is reserved bolt hole on semicircle, projection.Make during described anchor head, after cup 1 is in place, insert bolt 10, and make
Reserved 3 millimeters gap between two cup pieces 11, using encapsulant pay the seam, now cup 1 is that both sides have the hollow of projection
Cylinder.Chill casting filler 8 is irrigated, after its intensity reaches design requirement, the encapsulant in gap, strength screwing bolts is rejected
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 leads to
The bottom for being threadedly connected to cup 1 is crossed, caulking gum 5 is installed in the other end of connecting cylinder 4, and is compressed by closure 6.
Embodiment two
The corresponding schematic diagram of the embodiment is shown in Fig. 1 and Fig. 3.The difference of the embodiment and embodiment one is：Relatively
Two cups 11 contacted using corresponding teeth groove, two-part contact surface is not smooth, is made up of shaggy block.
Claims (3)
