The present invention relates to a thread clamping device (10) including a plurality of movable nut segments (16A-16D) around a threaded rod (11), and spring members (18,20) flexibly holding the segments against the rod. The thread clamping device (10) has a structure adapted to accommodate substantially planar outer surfaces of the segments engaging planar surfaces of the end housing (12) of the device, leading to a more robust device and improved performance. Such a thread clamping device can advantageously be used as a component of a self-adjusting shrinkage compensation device, a coupler for threaded rods, hold-downs, among other uses. Various embodiments of the thread clamping device includes a multi nut (100) configuration, a quick release, and including mechanical or magnetic clip attachments.
La présente invention concerne un dispositif de serrage de filetage (10) comprenant une pluralité de segments d~écrou (19A-16D) mobiles entourant une tige filetée (11) et d~éléments à ressort (18,20) maintenant de façon flexible les segments contre la tige. Le dispositif de serrage de filetage (10) a une structure adaptée pour loger les surfaces extérieures sensiblement planes des segments pénétrant les surfaces planes du boîtier final (12) du dispositif, permettant de rendre le dispositif plus solide et d~améliorer les performances. Un tel dispositif de serrage de filetage peut être utilisé de façon avantageuse comme partie intégrante d~un dispositif de compensation à réglage automatique, d~un dispositif de couplage de tiges filetées, d~un dispositif de fixation, entre autres. Divers modes de réalisation du dispositif de serrage de filetage comprennent une configuration à rainures multiples (100), un dispositif de relâchement rapide et des attaches de fixation mécaniques ou magnétiques.
