Tower and wind turbine generator

Abstract

A tower that includes a junction having a sufficient yield strength and can easily ensure the accuracy of used tower sections, and a wind turbine generator having the tower, are provided. The tower configured by stacking a plurality of tower sections in a vertical direction and connecting the tower sections to each other includes a connecting member arranged in the tower section, the connecting member dividing an inside of the tower section into a plurality of regions in a horizontal plane, and having at least one end connected to an inner wall of the tower section, and a frictional joint part for connecting by frictional joint the connecting member to another connecting member connected to another adjacent tower section.

What is claimed is: 
     
         1 . A tower configured by stacking a plurality of tower sections in a vertical direction and connecting the tower sections to each other, comprising:
 a connecting member arranged in the tower section, the connecting member dividing an inside of the tower section into a plurality of regions in a horizontal plane, and having one end connected to an inner wall of the tower section and the other end connected to the inner wall of the tower section or another connecting member; and   a frictional joint part for connecting by frictional joint the connecting member to another connecting member connected to another adjacent tower section.   
     
     
         2 . The tower according to  claim 1 , wherein the connecting member is in a shape of a flat plate. 
     
     
         3 . The tower according to  claim 2 , wherein an operating manhole is formed in the connecting member. 
     
     
         4 . The tower according to  claim 1 , wherein the connecting member extends on a position other than a centroid of a horizontal cross section of the tower section. 
     
     
         5 . The tower according to  claim 1 , wherein:
 the tower sections on the lower side of the tower are connected to each other by use of the connecting members; and   the tower sections on the upper side of the tower are connected to each other by use of flanges provided at respective ends.   
     
     
         6 . The tower according to  claim 1 , wherein the connecting members are arranged in a shape of a cross when viewing the tower section in a horizontal plane. 
     
     
         7 . The tower according to  claim 1 , wherein the connecting member includes a plurality of connecting members that extend in one direction to have both ends connected to the inner wall of the tower section and that are in parallel to each other. 
     
     
         8 . The tower according to  claim 1 , wherein
 the connecting member includes:   a first connecting member that extends in one direction to have both ends connected to the inner wall of the tower section; and   a second connecting member that has one end connected to the inner wall of the tower section and the other end connected to a midpoint of the first connecting member to form a substantially right angle with the first connecting member.   
     
     
         9 . The tower according to  claim 1 , wherein the connecting member includes a plurality of connecting members that each extend in one direction to have one end connected to the inner wall of the tower section, and that have the other ends, respectively, connected to each other. 
     
     
         10 . The tower according to  claim 1 , wherein:
 the connecting members are a plurality of connecting members that extend in one direction to have both ends connected to the inner wall of the tower section; and   the plurality of connecting members are arranged to form a polygonal shape in contact with the inner wall of the tower section when viewing the tower section in a horizontal plane.   
     
     
         11 . A wind turbine generator comprising the tower according to  claim 1 .
