The invention relates to a tower construction with an annular cross section, comprising one or more component tubes (1) arranged concentrically one on top of the other, wherein at least one component tube (1) is composed of at least 3 tube segments (2), the tube segments (2) of at least one component tube (1) are pretensioned relative to one another by means of tensioning devices, hereinafter referred to as segment tensioning devices, and the component tubes (1) have tensioning devices, hereinafter referred to as component tube tensioning devices, which act at least in the axial direction and extend over at least one horizontal joint (5), the tube segments (2) and the component tubes (1) composed therefrom form, at their butting edges, joints (3) having gaps (9), the gaps (9) of the joints (3) are filled at least partially with a joint-filling material (8), and the joints (3) between the tube segments of the same component tube allow a certain, substantially constraint-free rotation of the adjoining tube segments about the joint axis.
L'invention concerne un concept de tour comportant une section transversale annulaire et constituée par un ou plusieurs tubes partiels (1) concentriques superposés. Au moins un tube partiel (1) est composé de trois segments (2) de tube, et les segments (2) d'au moins un tube partiel (1) sont mutuellement précontraints par des dispositifs de serrage, ci-après nommés dispositifs de serrage de segments. Les tubes partiels (1) comportent des éléments de serrage, ci-après nommés éléments de serrage de tubes partiels, agissant au moins dans l'axe et couvrant au moins un joint horizontal (5). Les segments (2) de tube et les tubes partiels (1) en étant composés ont sur leurs bords des joints (3) comportant des espacements (9) au moins partiellement remplis de matière de charge (8). Les joints (3) entre les segments des tubes partiels permettent une certaine rotation sensiblement sans contrainte des segments de tubes adjacents autour de l'axe du joint.
