And described pilum is the multistory reinforced concrete frustum unit coaxial taper type structure that forms that installs mutually, is hollow structure in it.
And, coaxial insert reinforcing cage in the steel concrete of described each frustum unit, this reinforcing cage is a circular layer, or the multistory reinforced ring cage that is constituted by the bearing rod mode.
And the coaxial mode that vertically installs mutually in described frustum unit is to adopt the flange mode to carry out coaxial installing between the upper and lower adjacent frustum unit, adopts the bell and spigot mode to carry out coaxial installing between the perhaps upper and lower adjacent frustum unit.
And described steel concrete adopts steel fibrous concrete to substitute.
And described bottom frustum unit is reserved with an access of being convenient to later maintenance.
Advantage of the present utility model and beneficial effect are:
1. this wind power tower drum employing hollow taper type steel concrete installs the mode of steel king-post as pilum, on this pilum, has reduced the steel using amount of steel king-post effectively, has reduced manufacturing cost, has promoted the application popularization scope of wind-power electricity generation.
2. the pilum of this wind power tower drum has adopted steel concrete, and steel wherein are in the concrete alkaline environment, and it is well protected, thereby need not brushing rustproof paint often, has saved maintenance cost greatly.
3. the utility model overall structure is very simple, and design science is reasonable, efficiently solves cost height that existing wind-power electricity generation exists, keeps in repair difficult problem, and steel using amount reduces a lot; With respect to traditional sense all steel system tower tube, the utility model longer service life has permanent economic benefit more, fully alternative existing wind power tower drum.
