End connector is connected with rotary connector one end connector I of dimension, and rotary connector other end connector II is led with connection
The wirerope for drawing power device is connected；The value range of above-mentioned n is: the integer of 2≤n≤6.
Due to taking above structure, the utility model its " a kind of whole beam traction device of prestress wire " has with following
Beneficial effect:
1, since the outer diameter of the whole beam traction device of the utility model prestress wire can be accomplished to be less than steel wire bundle most
Small circumscribed circle diameter overcomes because traction device outer diameter is whole to prestressing tendon greater than steel wire bundle minimum circumscribed circle diameter
The more difficult disadvantage of body lashing.To be substantially reduced prestressing tendon in similar concrete segment pin-connected panel wind-power tower
The difficulty of whole beam traction.
2, heading mode of traction is used between the whole beam traction device of the prestress wire of the utility model and steel wire bundle,
High safety and reliability, ancillary equipment is few, and simple to operation.
3, construction method is easy: the positioning seat and drawing head of the whole beam traction device of the prestress wire of the utility model it
Between be connected through a screw thread, connection is reliable, convenient disassembly, greatly speeds up construction speed.
By it was verified that the utility model prestress wire whole beam traction device effective solution section assembling formula
The problem of the whole beam traction of prestressing tendon in concrete wind-power tower engineering, and construction efficiency is high, economy with higher
Property and practice significance.
With reference to the accompanying drawings and examples to a kind of skill of the utility model its " whole beam traction device of prestress wire "
Art feature is described further.
