The utility model is to realize like this, a kind of novel wind-power electricity generation precast concrete tower member longitudinal joint structure, comprise barrel one, barrel two, on the longitudinal joint surface of contact of barrel one and barrel two, be provided with positioning key spaced apart, it between adjacent positioning key, is the positioning spline matching with positioning key, the reserved duct that connects in described positioning key, and in duct, be embedded with steel pipe, after described positioning key and positioning spline contraposition, steel pipe in each positioning key inner duct is in same vertical position, and the through hole vertical direction in steel pipe runs through up and down, in the through hole running through in each steel pipe, be plugged with a rod iron.
Described steel pipe is externally connected with fixing joint bar vertical with steel pipe, and the described joint bar the other end extends in positioning key.
On described positioning spline, smear the epoxy resin that positioning key is gluedd joint in thick being used for of 1～2mm.
Described positioning key and positioning spline are at least two pairs, and after contraposition, seam surface of contact is broken line.
Described positioning key is for being wedge-type shape, the long 400mm in bottom, the long 207mm in top, the high 145mm of key; The long 210mm in positioning spline bottom, the long 403mm in top, groove depth 145mm, the thickness of barrel one and barrel two is 30cm～50cm.
The long 302mm of described steel pipe, diameter 42mm, thickness 2mm.
Described rod iron adopts HRB400, diameter 30mm, long 3.6m.
The beneficial effects of the utility model are: by embedded steel tube, be connected with high-strength steel bar, both sides tower cylinder is connected into integral body, finally by grouting form, guarantees that member forms integral body; Longitudinal joint face arranges keyway, can guarantee the good connection of longitudinal joint, has accelerated component assembly progress and merging precision, saved the time, method of construction is simple, easy construction, construction time does not recycle the equipment such as welding, smears epoxy resin can meet requirement of strength at surface of contact, can save the duration again; It is broken line that wedge shape positioning key capable of regulating surface of contact is set, thereby increases the area of contact between structure, better to the stress condition of structure.
