Description
Technical field
The invention belongs to prestressing force steel reinforced concrete tower technique fields, and in particular to a kind of novel pre-stressed steel reinforced concrete pylon changeover portion
Conversion equipment.
Background technique
With the fast development of China's wind-powered electricity generation industry, the preferably land Construction of Wind Power of wind-resources is gradually saturated, the following wind
Electric field exploitation will gradually develop to low wind speed area, and Wind turbines develop to big single-machine capacity, large impeller diameter and high tower.Steel reinforced concrete
Pylon lower part uses armored concrete tower, and top uses steel tower drum, and basis uses disc reinforced concrete structure, three
It is connected by prestress wire, is able to satisfy the requirement of large-scale wind electricity machine unit hub height and rigidity, is obtained in wind-powered electricity generation field
Extensive concern and popularization and application.
For the changeover portion that concrete tower is connect with steel tower tube there are rigidity mutation problems, changeover portion is the weakness of steel reinforced concrete pylon
Link and key technology difficulty need to carry out reinforcement design to it.The connection type of traditional steel reinforced concrete pylon changeover portion generallys use L-type
Flanged joint, which need to select the thick flange of solid forging shaping, with the increase of tower height and diameter, therewith
The flange thickness matched is more and more thicker, to increase the cost of raw material and machining cost.On the other hand, matched with L-type flange
Bolt assembly length is limited by the thickness of flanged plate, causes the connection bolt length of L-type flange shorter, anti-fatigue performance is poor；This
Outside, the loss of prestress of bolt is influenced very big by the malformation of junction, therefore it is prestressed effectively to control bolt
Size, it is difficult to which tower junction is in pressured state always during guaranteeing fan operation.
