The invention concerns a section of a carrying column of a wind turbine with vertical shaft. The section is hollow and elongate and comprises a wooden frame essentially of wood. According to the invention, the section has a joint part at each end. Each joint part comprises an end portion of the wooden frame and at least one joint component of polymer. The joint component (14) has a flange (13) directed transversely to the longitudinal direction of the section and an anchoring part (15) that is directed along the end portion and extends along the outside and/or inside of the end portion. The invention also concerns a method for the manufacture of a carrying column of a wind turbine with vertical shaft, in which the carrying column is joined together by means of such sections.
