Abstract
The utility model discloses a concrete-steel structure composite wind power tower, which comprises a foundation and a tower body, and is characterized in that the foundation adopts a hollow disc structure and a steel flange is pre-buried at the upper end of the foundation; the tower body adopts a cone-shaped structure and is divided into a plurality of tower sections including concrete tower sections and steel tower sections, steel flanges are pre-buried at two ends of each tower section, and reinforcing ribs are pre-arranged on the steel flanges at the parts buried into the concrete tower sections and the foundation; connection holes are uniformly arranged on the circumference of the steel flanges corresponding to the cavity of the tower body; the connection holes of the steel flanges of the foundation, the tower body, and the two adjacent tower sections are aligned, and high-strength bolts penetrate the connection holes and are fixed by nuts at two ends. The wind power tower is convenient for transport and hoisting, and is low in cost.
Description
Technical field
The utility model belongs to wind power plant, the compound wind power tower of particularly a kind of concrete-steel work.
Background technology
Domestic in recent years wind-powered electricity generation building size is bigger, development is very fast, the wind power tower industry is gradually to maximization, heavy-duty and development in pluralism, wind power tower is the important component part of wind power plant, existing main flow wind power tower adopts steel cone barrel integral structure, in wind power equipment, wind power tower accounts for 30% of whole cost, and manufacturing cost is higher relatively; Along with wind power generating set power constantly increases, also more and more higher to height, the requirement of strength of wind-power electricity generation pylon, but the size of unlimited increase pylon will be brought very big difficulty to transportation.
Summary of the invention
At the deficiency that existing wind power tower exists, the utility model provides a kind of and is convenient to transport and lifting, the compound wind power tower of concrete-steel work with low cost.
For achieving the above object, the utility model adopts following technical scheme:
The compound wind power tower of a kind of concrete-steel work comprises pedestal and tower body, it is characterized in that: described pedestal is a hollow disc shape structure, adopts prestressed reinforced concrete to make, and its upper end is embedded with steel flanges; Described tower body is the cone barrel structure, and tower body is divided into n tower section, n 〉=2 on short transverse, hop count n determines according to tower body actual needs height, the tower section comprises concrete tower segment and steel tower section, and concrete tower segment adopts prestressed reinforced concrete to make, and the two ends of tower section are embedded with steel flanges; The steel flanges circumferential position corresponding with the tower body cavity evenly is furnished with connecting hole; The connecting hole of the steel flanges of pedestal and tower body and adjacent two tower sections aligns, and high-strength bolt runs through connecting hole and two ends utilize nut to fix.
Described steel flanges is imbedded the default stiffener of part of concrete tower segment and pedestal.
Convenient transportation of wind power tower that the utility model provides and lifting, pylon structure closes manufacturing by concrete and steel reinforced concrete, effectively reduces the wind power equipment fabricating cost and has guaranteed the intensity of pylon, and steel tower section also can be used for connecting the parts of main frame or other needs simultaneously.
