Specific embodiment
Exemplary embodiment disclosed by the utility model is more fully described below with reference to accompanying drawings, these embodiments be for
It can thoroughly understand the utility model, and range disclosed by the utility model can be communicated completely to this field
Technical staff.Although showing exemplary embodiment disclosed by the utility model in attached drawing, it being understood, however, that this is practical new
Type and should not be limited by the embodiments set forth herein.
A kind of compound connection by post-installed fastenings device of ductility, including anchor pole 1, locking nut 2, anchor slab 3, baffler A4, rubber stopper
A5, binder 6, steel bushing 7, rubber stopper B9, baffler B10.Wherein, anchor pole 1, locking nut 2, anchor slab 3, baffler A4, steel
Sleeve 7 and baffler B10 are all made of stainless steel material and are made.Baffler A4, rubber stopper A5, binder 6, rubber stopper B9 and barrier
The equal housing of plate B10 is set to the outside of anchor pole 1, and is integrally located at the inside of steel bushing 7.
The inside of steel bushing 7 is provided through anchor pole 1, and anchor pole 1 opens screw thread axially outside, and screw thread is spiral burr.
The tail portion welding of anchor pole 1 is equipped with baffler B10, and baffler B10 and anchor pole 1 are in unitary design, and baffler B10 is
Circle, outer diameter are equal to the internal diameter of steel bushing 7.The top baffler B10 is equipped with rubber stopper B9, and rubber stopper B9 is circle, and outer diameter is bigger
In the internal diameter of steel bushing 7.
Binder 6 is poured into above rubber stopper B9, the material of binder 6 is the mixture of modified cement and water；Modified water
