The corresponding card interface of strand locations, and steel strand wires both pass through card interface, and the one end of the oviduct away from about collar is set
There is work anchor slab, the end of the steel strand wires through work anchor slab and is fixedly connected with work clip sheet, the outer wall set of the oviduct
Equipped with spiral bar, the outer wall of the oviduct is plugged with grouting short tube.
Preferably, the abutment sleeve is unilateral closing conical sleeve, its top outer wall is uniformly provided with extravasating hole.
Preferably, multiple card interfaces are circumferentially distributed in the top outer wall of abutment sleeve, and the madial wall of card interface
Circumferentially offer wedge groove.
Preferably, anchor plate is clamped between the oviduct and work anchor slab, and steel strand wires run through anchor plate.
The utility model proposes a kind of highway bridge construction prestressed anchor, beneficial effect is：By in loudspeaker
Bonding abutment sleeve, steel strand wires pass through abutment sleeve through card interface inside pipe, and card interface carries out clamping positioning to steel strand wires, avoids
There is the situation of steel strand wires distortion in installation process in the stress anchorage, ensure that steel strand wires pass through loudspeaker with natural angle
Pipe so that every steel strand wires are more uniformly stressed, and reduce the risk that steel strand wires are broken by unbalance stress.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of highway bridge construction prestressed anchor structure diagram；
