Zusammenfassung:	PURPOSE: To provide a tower which is provided with comparatively large weather resistance and bending stress by means of at least three concrete columns and a steel brace. CONSTITUTION: An endless steel band 2 is rolled in the outer circumferential face of a prestressed concrete column 1 while setting its outer circumferential face on the same outer circumferential face of the concrete column 1, and on the inner circumferential face of the band 2, a box nut 3 integrated with the band 2 is buried in concrete 4 of the concrete column 1. An opening part of the box nut 3 is opened by means of a fixed through hole 5 bored in the band 2, and one end of a brace 8 is connected to a butt strap 7 mounted to the box nut 3 by means of a bolt 6, and then plural concrete columns 1 are connected together by means of the brace 8.
