Background technique
The wind-powered electricity generation energy is a kind of pollution-free, reproducible clean energy resource.Compared with the land wind-powered electricity generation energy, the offshore wind farm energy
With wind turbine power generation amount, high, single machine installed capacity is bigger, fan operation is more stable, wind power plant construction is excellent without land occupation etc.
Gesture starts the extensive concern by national energy authorities and industry in recent years.
The size of blower is increasing in recent years, and required tower height and diameter are also increasing, and traditional blower is more
Using the tower of steel flanged beam, this tower wind area is larger, and material utilization amount is more, therefore, wide in order to sufficiently develop China
Marine wind energy resource, reduce tower load and material utilization amount, need to make improvements conventional tower cartridge form, the property developed
It can optimal tower form.
Summary of the invention
Present invention synthesis proposes a kind of hybrid blower fan pylon of prefabricated PC lattice concrete filled steel tube: pylon is lattice
Structure formula column can significantly reduce the wind load acted on pylon, and each rod piece is primarily subjected to axial force, so as to make full use of material
Intensity, limb part use concrete filled steel tube, the dosage of steel can be reduced, and prestressing force is applied to it, improve its tensile property.Knot
Structure simple structure, vertical and overall stability are good, are a kind of completely new offshore wind turbine pylon forms, structural system is all using dress
With mode of construction is changed, it is remarkably improved construction efficiency, guarantees construction quality, reduce working measure expense.
Technical scheme is as follows:
A kind of hybrid blower fan pylon of prefabricated PC lattice concrete filled steel tube.The structure includes blower, upper column
Cylinder, annular steel box-girder, lattice tower, basis.The direct injection basis in each limb part lower part of the lattice tower, topmost
The annular steel box-girder replacement of horizontal bars, annular steel box-girder is bolted with top tower；The structure is in upper column
A Fans are arranged on cylinder.
The lattice tower is lattice column, and each limb part is pre-stressed steel pipe concrete, using post stretching, and it is pre-
The duct of tensioned prestressing bar has been stayed, presstressed reinforcing steel is worn in duct, limb part can be segmented according to its length, be adopted between each section
Use flanged joint；It, which respectively sews bar, to be empty steel pipe or concrete filled steel tube.
The present invention has the advantages that compared with the existing technology
(1) pylon is lattice column, can reduce the dosage of material, and rod piece is primarily subjected to axial tension or pressure, so as to
The intensity of material is made full use of, while lattice tower wind-engaging Loading Area is small, the wind lotus acted on pylon can be significantly reduced
It carries；
(2) the limb part of lattice tower use concrete filled steel tube, can effectively reduce steel pipe thickness, reduce welding workload,
Reduce steel using amount；
(3) structural system all uses assembling mode of construction, is remarkably improved construction efficiency, guarantees construction quality, drop
Low working measure expense.
