Device for connecting or attaching components using an extremely secure pretensioning screw connection and screw set for extremely secure pretensable connections

摘要

a method for combining is proposed and fixing of components using a vorspannbaren schraubverbindung solemnity. furthermore, a schraubengarnitur is proposed for such joints.;in the context of the procedure used for fitting consists of a screw (1), consecutively, a head, a shaft and a gewindeabschnitt which, with the schaftdurchmesser in the schaftabschnitt (3) is equal to or smaller than the standard pitch diameter (d). the mother, (2) the schraubengarnitur can mehrkantabschnitt and a circular section (11)).a ziehendes vorspannverfahren by means of a hydraulic schraubenspannzylinders (20) for the schraubverbindung to be able to use the foreign on the mother (2) protruding gewindeabschnittslu00e4nge (l) of the screw (1) is at least equal to 0.5 times of the gewindeauu00dfendurchmessers (d) of the screw.the mother (2) is either directly on the verschraubenden component (7), or alternatively in a unterlegscheibe intermediate layer (30). when using the unterlegscheibe (30) is that it increases in diameter, so that an annular abstu00fctzflu00e4che (32) for the schraubenspannzylinder (20) are available.
