Change steel tube tower, angle steel tower is widely used in 10kv, 35kv and 110kv ultra-high-tension power transmission line and communicates on shaft tower.With new
One wheel electric network reconstruction upgrading, the shaft tower appearance of multiloop, high intensity certainly will require the big tip diameter prestressed concrete electric pole of big moment of flexure
Assembled length increases, and electric pole longest assembled length is up to 48m.Currently, the big big tip diameter assembling electric pole group joint of moment of flexure is mostly adopted
With steel plate ring welding point, assembled length also has less than 18m's using flange bolt connecting joint, but be confined to central flange or
Flange at bottom, that is to say, that the big big tip diameter prestressing force assembling bar of moment of flexure can only be assembled at present with a connector.Because of overlength bar tier pole
When need larger place, and due to overlength pole length is big, from great, the crane integral lifting of large-tonnage is needed, in hillside, rice field
Equal positions construction tier pole welding is difficult the place for having requirement, and large crane also is difficult to enter construction site, so gives construction
Very big inconvenience is brought, or even cannot be constructed, overlength assembling bar operating expenses is expensive in addition, gives the big tip diameter prestressing force of big moment of flexure
The popularization and application of concurrent bring difficulty, limit purposes, also reduce use scope.
In order to facilitate overlength assembling bar upright bar construction, mounting cost is reduced, all assembling rod segments use flange connecting joint
And do not have to steel plate ring welding point, basis is first poured in assembling, one section of one section of ground up docks, and is fastened with bolt.But at present
Flange assembling bar can only assemble a connector, i.e. the flange of root one or one, middle part flange, both ends has bump joint simultaneously
Overlength assembling bar do not occur also.There is provided a kind of tensioning equipment of the bump joint for tensioning stage casing electric pole becomes this field skill
Art personnel there is an urgent need for.

End is inserted in the spike set.
As the further preferred of above-mentioned technical proposal：The tensioning internal tooth is cyclic annular and along the circumferential direction of the sleeve lining
Arrangement, the tensioning ring flange is identical as the tensioning internal tooth thickness and is set to the barrel end end.
Advantageous effect
Compared with the prior art, the advantages of the present invention are as follows：
1, using tensioning ring flange, the prestressed electric wire pole of the flanged connector in both ends can be produced, that is, produces stage casing bar, Neng Gouyong
In the overlength for assembling three sections and three sections or more（> 18m）The prestressed concrete electric pole of flange connecting joint, it is existing so as to cancel
There is the fixation disk in tensioning equipment, simplifies tension operation, it is time saving and energy saving.
2, tendon ring and tensioning internal tooth are set in sleeve, reinforcing bar is through on tendon ring wears fixation through plating head, and tensioning internal tooth is then
It is engaged with the tensioning external tooth of tensioning head, realizes the prestressed stretch-draw of tensioning ring flange, it is simple and reliable for structure, it is easy to use.
3, bolt is worn on tensioning ring flange, locking nut on bolt, tensioning, which finishes, sheds tensioning head, lock-nut
It screws and withstands tensioning flange plates, punching block end plate is withstood on standing screw head, will be applied to the reinforcing bar in prestressed concrete electric pole
The prestressing force added is transferred to by tensioning ring flange on punching block, completes tension process, and bolt can be fixed on any position of punching block, is grasped
Facilitate, and tensioning ring flange is fixed on the end plate of punching block due to the prestressing force of application, when centrifugation will not be skimmed, operation peace
Entirely.
