A kind of wind-driven generator tower and jacket basis polygonal diagonal brace linkage structure as mentioned above is characterized in that: bracing element is the polygonal bracing element of the inner hollow that is spliced of plurality of plates.
A kind of wind-driven generator tower and jacket basis polygonal diagonal brace linkage structure as mentioned above, it is characterized in that: plate is flat board or arc plate.
A kind of wind-driven generator tower and jacket basis polygonal diagonal brace linkage structure as mentioned above, it is characterized in that: the cross section of bracing element is uniform section from its upper end to the lower end.
A kind of wind-driven generator tower and jacket basis polygonal diagonal brace linkage structure as mentioned above is characterized in that: the cross section of bracing element is the gradual change cross section of increase gradually from its upper end to the lower end.
A kind of wind-driven generator tower and jacket basis polygonal diagonal brace linkage structure, is characterized in that: be provided with vertical and/or horizontal stiffening plate in bracing element as mentioned above.
A kind of wind-driven generator tower and jacket basis polygonal diagonal brace linkage structure, is characterized in that: be provided with vertical and/or horizontal stiffening rib in bracing element as mentioned above.
A kind of wind-driven generator tower and jacket basis polygonal diagonal brace linkage structure as mentioned above is characterized in that: face mutually between two bracing elements and be connected by connecting plate, be fixedly attached on generator tower cylinder after making many bracing elements be linked as an integral body.
The utility model with respect to the beneficial effect of prior art is:
1, in the utility model, be connected with many bracing elements between jacket basis and generator tower cylinder, the cross section of bracing element is polygonal, due to this employing polygonal cross-section bracing element, intersecting line length that can be by changing bracing element and generator tower cylinder and the position of intersecting line increase the area of contact of bracing element and generator tower cylinder, can also come enlarge active surface by sectional dimension and the bracing element thickness of slab that changes bracing element and generator tower cylinder joint, to strengthen the bearing capacity on basis, improve the distribution of force of generator tower cylinder and bracing element.
2, to adopt the cross section of many plates splicings be polygonal bracing element to bracing element, and when production and processing, technique is simple, and precision easily guarantees, and lightweight, and cost is low.
