Further, described reinforcing bar is Ribbed Bar.
Further, described anchor plate end plate is not less than long-pending 9 times of bar cross section perpendicular to the clean cross-sectional area in the cross section in sleeve direction.
Further, the thickness of described anchor plate end plate is more than or equal to the diameter of described reinforcing bar.
Further, the shape of described anchor plate end plate is circular, oval, square or polygon.
Further, described hole is screwed hole, and described hole is no less than 2, and distance between described hole is equal, and the specification of quantity basis reinforcing bar and the tensile strength of reinforcing bar of screwed hole are determined.
Further, the inwall of described sleeve is through sandblasting or indentation process.
Further, the tensile strength of described sleeve is not less than the tensile strength of described reinforcing bar, and sleeve diameter, wall thickness and length are determined according to the specification of institute's connecting reinforcement.
Further, the internal diameter of described sleeve is greater than the diameter of described reinforcing bar, and the difference of the internal diameter of described sleeve and the diameter of described reinforcing bar is 1mm-10mm.
Installation steps of the present utility model are as follows,
A) reinforcing bar is inserted in the sleeve on anchor plate, end reinforced deeply to sleeve bottom;
B) rotating the upper sleeve of anchor plate makes reinforcing bar have screwed hole in the side alignment sleeve of rib tooth;
C) successively screw is screwed in screwed hole;
D) tighten screw with electric wrench, until twist into two parts the nut on screw, make screw can resist Steel Bar Tensile Strength to the extruding force of reinforcing bar, complete installation steel bar anchoring device.
Compared with prior art, the utility model has the following advantages:
1. do not need reinforcing bar and sleeve lining thread cutting, can batch production, standardized production;
2. can install on the spot at scene when installing, also can factory-assembled, construct simple, efficient and convenient;
3. the construction level of pair installation personnel requires lower, only need twist into two parts with the nut of instrument by screw, construction quality is easy to control, and avoids that adopting is threaded and need control the moment of torsion of spanner, adopts and be welded to connect and construction quality more rambunctious difficulty higher to welder's welding level requirement;
4. the construction environment such as pair on-the-spot weather, temperature requires lower, and sleet sky, low temperature environment all can be constructed, and to avoid when adopting welding sleet sky and temperature compared with the shortcoming of welding unsuitable under low environment.
