On the other hand, with the raising of China's steel manufacturing technology, the increase of steel yield, Q420 and higher intensity
Steel have appeared on the market.But the strength of materials is only greatly improved in such high strength steel, and elasticity modulus increase is smaller, therefore structure
Part rigidity improves less, therefore the stability of structure can not be significantly improved by being directly used in wind-power tower.In conclusion developing and grinding
Study carefully novel wind-powered electricity generation pure steel structure tower, make the stability of tower and intensity while being improved, to meet high-power and high tower
The requirement of cylinder Wind turbines, is necessary.
Summary of the invention
The present invention proposes a kind of wind-powered electricity generation pure steel structure tower for having double mechanism of putting more energy into-carry: the system top is general
Logical steel tower tube, lower part are high-strength steel tower tube.High-strength steel tower tube is made of barrel and ribbed stiffener.Barrel and ribbed stiffener are strong using surrender
High strength steel of the degree not less than 420MPa is made.Ribbed stiffener is welded on the inside of barrel, is circumferentially evenly arranged, ribbed stiffener
Upper and lower end is welded with the upper flange plate of each tower segments, lower flange plate respectively.Band crimping steel can be used in the section form of ribbed stiffener
Plate, U-shaped steel or T steel.When bottom section size is larger, high-strength steel tower tube can be assembled by 2~4 high-strength steel sheels.
The system can improve the strength and stability of tower simultaneously, give full play to the effect of high strength steel, can reduce wall thickness,
Saving construction cost, construction and convenient transportation, have wide future in engineering applications.

The system top is common steel tower tube, and lower part is high-strength steel tower tube；High-strength steel tower tube is made of barrel and ribbed stiffener.
High strength steel of the barrel and ribbed stiffener of high-strength steel tower tube using yield strength not less than 420MPa is made.It puts more energy into
Rib is welded on the inside of barrel, is circumferentially evenly arranged.The upper and lower end of ribbed stiffener respectively with the upper flange plate of each tower segments, laxative remedy
Blue plate welding.Band crimping steel plate, U-shaped steel or T steel can be used in the section form of ribbed stiffener.
When bottom section size is larger, required to meet construction and transport, high-strength steel tower tube can be by 2~4 high-strength steel
Shell is assembled.The end welded bands crimping steel plate and prepared screw-bolt hole of high-strength steel sheel, adjacent high-strength steel sheel pass through spiral shell
It tethers and connects.The inner wall of high-strength steel sheel is evenly arranged ribbed stiffener, the upper and lower end of the ribbed stiffener upper flange with each tower segments respectively
Plate, the welding of lower flange plate.
The present invention has the advantages that compared with the existing technology
(1) tower barrel is made of high strength steel, and high strength steel ribbed stiffener and barrel and upper and lower flanged plate is arranged
Close connection, common stress improve the strength and stability of tower all largely.
(2) tower is decomposed into 2~4 high-strength steel sheels, and fragment carries out production and assembly, solves tower sectional dimension
Transport and the problem of constructional difficulties when larger.
