Abstract
The present invention provides a kind of novel high-strength anchorages, including anchor cup, compressor wire, wire sub-panel, it is characterised in that: wire sub-panel is placed in anchor cup, and compressor wire passes through anchor cup and wire sub-panel, is fixed on the end face of wire sub-panel.The taper of first tapered hole of anchor cup is that the taper of the 0.1~0.2, second tapered hole is 0.2~0.3, second tapered hole uses the taper bigger than the first tapered hole, axially loaded is more converted by wire sub-panel stress, it is more conducive to axial force carrying, the force stability for increasing anchorage reduces the deformation of anchor cup.Wire sub-panel body outer surface taper is consistent with the taper in steep-taper hole of anchor cup, the radius of curvature of groove and the radius ratio of filament plate ontology are 1:1, so that the uniform force on wire sub-panel, threaded hole of steel is directed toward the vertex of the first tapered hole of anchor cup, reduces wire sub-panel and damages to the shearing of steel wire.The present invention improves the intensity and service life of anchorage, practical, easy to spread, good in economic efficiency.
Description
Technical field
The present invention relates to a kind of prestressed anchors, more particularly, to a kind of novel high-strength anchorage.
Background technique
Prestressed anchor is widely used in the fields such as bridge, building, still, the threaded hole of steel on currently used anchorage wire sub-panel
It is all perpendicular to sub-wire plate surface, so that wire sub-panel causes cutting to damage on steel wire, reduces the bearing capacity of anchorage, and
Wire sub-panel is mostly slab construction, so that wire sub-panel discontinuity, centre stress is maximum, in big load in use, holding
It is easily cracked impaired, and the anchor cup of anchorage is all using same taper at present, and radial component is larger, be easy to cause anchor cup
Radial deformation, the prestressed anchor for designing a kind of high intensity thus are very necessary.
Summary of the invention
In order to overcome deficiency existing for existing anchorage, the present invention provides a kind of novel high-strength anchorages.
The present invention is adopted the technical scheme that in order to achieve the above objectives: a kind of novel high-strength anchorage, including anchor cup
(1), compressor wire (2), wire sub-panel (3), it is characterised in that: wire sub-panel (3) is placed in anchor cup (1), and compressor wire (2) is worn
Anchor cup (1) and wire sub-panel (3) are crossed, is fixed on the end face of wire sub-panel (3).
The anchor cup (1) includes anchor cup ontology (101), the first tapered hole (102), the second tapered hole (103), clear opening
(104), inner hole is divided into three parts, respectively the first tapered hole (102), the second tapered hole (103), clear opening (104), the first cone
The taper of degree hole (102) is that the taper of the 0.1~0.2, second tapered hole (103) is 0.2~0.3.
Wire sub-panel (3) includes wire sub-panel ontology (301), groove (302), threaded hole of steel (303), and wire sub-panel ontology (301) is outside
Surface Taper is consistent with the taper in steep-taper hole (103) of anchor cup (1), the radius of curvature of groove (302) and filament plate ontology (301)
Radius ratio be 1:1, threaded hole of steel (303) be directed toward anchor cup (1) the first tapered hole (102) vertex.
The beneficial effects of the present invention are:
A kind of novel high-strength anchorage of the invention, anchorage wire sub-panel uses spherical groove structure, so that the stress on wire sub-panel
Uniformly, the threaded hole of steel on wire sub-panel is overlapped with the vertex of the first tapered hole of anchor cup, is reduced wire sub-panel and is damaged to the shearing of steel wire
Evil, the second tapered hole use the taper bigger than the first tapered hole, more convert axially loaded for wire sub-panel stress, more added with
Conducive to axial force carrying, the force stability of anchorage is increased, the deformation of anchor cup is reduced.The present invention improve anchorage intensity and
Service life, it is practical, it is easy to spread, it is good in economic efficiency.

Specific embodiment
Below in conjunction with attached drawing, present invention is further described in detail.
If Fig. 1 is structural schematic diagram of the invention, a kind of novel high-strength anchorage, including anchor cup (1), compressor wire
(2), wire sub-panel (3), it is characterised in that: wire sub-panel (3) is placed in anchor cup (1), and compressor wire (2) passes through anchor cup (1) and divides
Filament plate (3), is fixed on the end face of wire sub-panel (3).The anchor cup (1) include anchor cup ontology (101), the first tapered hole (102),
Second tapered hole (103), clear opening (104), inner hole are divided into three parts, respectively the first tapered hole (102), the second tapered hole
(103), clear opening (104), the taper of the first tapered hole (102) are that the taper of the 0.1~0.2, second tapered hole (103) is 0.2
~0.3, the second tapered hole uses the taper bigger than the first tapered hole, more converts axially loaded for wire sub-panel stress, more
It is carried added with axial force is conducive to, increases the force stability of anchorage, reduce the deformation of anchor cup.Wire sub-panel (3) includes wire sub-panel
Ontology (301), groove (302), threaded hole of steel (303), the steep-taper hole of wire sub-panel ontology (301) outer surface taper and anchor cup (1)
