The invention discloses a concrete filled
steel tube lattice type
wind power tower based on a corrugated steel web
box girder, and relates to the technical field of land
wind power generation. The
system comprises a fan, an upper steel
tower cylinder, an annular steel-concrete combined
box girder, a lattice type
tower and a foundation. The lower portion of each limb piece of the lattice type toweris directly anchored in the foundation, and the uppermost portion of the lattice type tower is connected with the upper steel tower cylinder through the annular steel-concrete combined
box girder. Each limb piece of the tower is a prestress
steel tube constraint concrete column, and a post-tensioning method is adopted to ensure that each limb piece only bears pressure, so that the compression resistance of concrete and the tensile property of steel are fully utilized; the limb pieces can be segmented according to length of the limb pieces, and each segmented splicing part is provided with ananti-shearing short
steel tube; each gusset piece is the corrugated steel web box girder, whether the concrete is poured is selected according to the stress demand, the gusset pieces are connected with the limb pieces through bolts, the
structural system adopts wholly an
assembly consturction mode, the construction efficiency can be remarkably improved, the construction quality is guaranteed, andthe construction measure cost is reduced.
