The specific embodiment
Below the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 3, the utility model embodiment comprises:
A kind of recoverable prestressed anchor device, comprise: anchoring section 1 and free segment 2, between described anchoring section 1 and free segment 2, by the first connector 3, be fixedly connected with extruding anchor 4, one end of described anchoring section 1 be arranged on the first connector 3 inner and with the first connector 3 between be threaded, described anchoring section 1 adopts glass fiber to make, intensity is high, can guarantee the steadiness being threaded under normal temperature.
Between described the first connector 3 and extruding anchor 4, be welded to connect, described free segment adopts reinforcing bar or steel strand to make, and with extruding anchor 4 between by extruding, be connected.
By said structure, make between anchoring section 1 and free segment 2 stable connection at normal temperatures, there is higher tensile strength.
Described the first connector 3 inside are also equipped with a high temperature service 5, between described high temperature service 5 and anchoring section 1, contact, described anchoring section 1 adopts glass fiber to make, after anchor device is finished using, by the glass fiber of high temperature service 5 softening the first connector 3 inside, anchoring section 1 and the first connector 3 are departed from, and final the first connector 3, extruding anchor 4 and free segment 2 are reclaimed, so that recycling.
