Description
Technical field
The present invention relates to bridge construction fields, and in particular to a kind of novel parallel steel wire HiAm anchorage and preparation method thereof.
Background technique
Currently, largely with parallel wire stay system as its main bearing member, Yi Taoping in Bridges in Our Country engineering
Row wire digging line system mainly bears the load of structure with cable body and both ends anchorage.Parallel wire stay system is as bridge
An important component in engineering, production are typically all to be made in workshop in specialized factory, by steel wire essence
Manufacture crafts, the last reels such as true blanking, steel wire row silk twisting, extrusion molding, HiAm anchorage perfusion transport to engineering site.
The essential step as parallel wire stay manufacture craft is perfused in HiAm anchorage, and fabrication cycle and production quality are serious
Production Time and the quality of parallel steel wire oblique pull cable system are restrict, to influence the construction procedure of science of bridge building, and to whole
The safety of a bridge generates strong influence.
Currently used HiAm anchorage mainly by: anchor cup, wire sub-panel, chill casting filler etc. form.Anchorage is packed into rope when production
In body, steel wire is respectively penetrated in the corresponding hole location of wire sub-panel, and carries out pier nose processing in the end of steel wire, finally carries out chill casting
The perfusion of material.
In the filling process of HiAm anchorage, steel wire, which penetrates wire sub-panel this process, will expend a lot of manpower and time,
When especially parallel steel wire quantity increases, and during wearing silk, steel wire fallibility hole is done over again, and need to be taken a substantial amount of time.
For example number of patent application is " the chill casting anchorage equipped with spherical surface wire sub-panel " of CN201120041747.3, uses and divides
Filament plate fixes parallel steel wire, to expend a lot of manpower and time, steel wire easily misdraws hole and does over again, while in the process of pier nose
In, steel wire end can be by certain damage.
Summary of the invention
(1) technical problems to be solved
The object of the present invention is to provide a kind of novel parallel steel wire HiAm anchorages, and solving existing novel parallel steel wire HiAm anchorage makes
Parallel steel wire, bothersome defect that is laborious, being easy error are fixed with wire sub-panel.
It is a further object to provide a kind of novel parallel steel wire HiAm anchorages, solve the existing mistake in pier nose
Cheng Zhong, steel wire end can be by certain damage, and pier nose quality always will appear difference, will lead to steel wire anchoring efficiency it is insufficient and
It is variant between each other, to generate stress unevenness, have the defect having a certain impact to the pouring quality of chill casting.
(2) technical solution
In order to solve the above technical problem, the present invention provides a kind of novel parallel steel wire HiAm anchorage, comprising: anchor cup, inside dress
There are several fixing sleeves, fixation hole is equipped in the fixing sleeve, the fixation hole and steel wire one end are interference fitted.In a first aspect,
The present invention provides a kind of novel parallel steel wire HiAm anchorage, and the fixing sleeve of steel wire is slightly less than with the diameter being inserted in every steel wire end
Form, substitute the wire sub-panel structure of original HiAm anchorage, when production, be not required to the correspondence for penetrating wire sub-panel one by one by steel wire
In hole location, only it need to be inserted in the fixing sleeve that internal diameter is slightly less than steel wire every steel wire end, connected between fixing sleeve and steel wire for interference
It connects.The present invention is solved existing novel parallel steel wire HiAm anchorage and is fixed parallel steel wire using wire sub-panel, bothersome laborious, easy
The defect of error.This invention also solves parallel steel wire HiAm anchorages in the prior art during filling anchor, and steel wire penetrates wire sub-panel
The problem of Shi Gangsi and wire sub-panel corresponding aperture dislocation position are done over again provides a kind of novel parallel steel wire HiAm anchorage, and every steel wire is certainly
The fixing sleeve for being slightly less than steel wire by being inserted in diameter under state, it is mutually indepedent between fixing sleeve, to steel wire before axial force preload
Radial position there is no limit effect, each steel wire may be at optimum position, when having avoided wire sub-panel structure, because misdrawing hole location
And lead to the case where frequently doing over again.
Second aspect, existing during pier nose, steel wire end can be by certain damage, and pier nose quality always goes out
Existing difference, the anchoring efficiency that will lead to steel wire is insufficient and variant between each other, so that stress unevenness is generated, to chill casting
Pouring quality tool have a certain impact.This invention also solves parallel steel wire HiAm anchorages in the prior art in the process for filling anchor
In, when steel wire end carries out pier nose operation, damage and pier nose qualitative difference to steel wire end, and the anchoring of steel wire is caused to be imitated
The problem of rate and stress unevenness, provides a kind of novel parallel steel wire HiAm anchorage, and every steel wire only need to be inserted in internal diameter in end
It is slightly less than the fixing sleeve of steel wire, is connected between fixing sleeve and steel wire for interference, be not required to again operate steel wire ontology, avoid
The damage of steel wire, when parallel steel wire cable body blanking, every steel wire length is consistent, and internal diameter is slightly less than the ruler of the fixing sleeve of steel wire
It is very little to be also consistent, therefore can guarantee that the stress of every steel wire is consistent.
Preferably, the lateral surface of the fixing sleeve is truncated cone-shaped, and the outer diameter of bottom end is greater than top outer diameter；The anchor cup
Inner sidewall at least locally has the conical surface compatible with fixing sleeve lateral surface.On the other hand, " inner sidewall of anchor cup at least locally has
Have the conical surface compatible with fixing sleeve lateral surface " with reference to first aspect, change the interior coning angle of existing anchor cup, cooperates fixing sleeve shape
The auto-lock anchorage of pairs of parallel wire unit end.
