The invention relates to a T-nut insertion method and an apparatus (1) of the type for driving T-nuts into e.g. a wooden work piece (4) with predrilled holes (5). A T-nut strip with improved and controllable rupture characteristics is also disclosed. Finally, embodiments of T-nuts with T-nut strip cutting protrusions or shapes are also disclosed. By applying the method according to the invention, a safe and precise insertion of T-nuts is obtained without the risk of T-nuts accidentally being driven from the apparatus (1) and without the risk of the T-nuts being driven into the work piece (4) at locations beside the predrilled holes (5).

Un système d'attache pour panneaux composites appartenant à la catégorie des panneaux comprenant une dalle frontale (10) de finition en pierre naturelle ou autre matériau, d'une épaisseur adéquate, et une couche de support multicellulaire (11). Le système d'attache comporte un corps creux de forme oblongue, pouvant être inséré dans un trou de fixation du panneau composé par le support multicellulaire (11) et la dalle frontale (10). Le corps creux du système d'attache comprend une tige tubulaire présentant des ailettes extérieures servant de fixation au support multicellulaire (11), et une tête expansible pour fixation à la dalle frontale (10), reliés par un prolongement flexible de la tête tubulaire. Le système d'attache comporte en outre un dispositif d'expansion qui se visse à la tige tubulaire, destiné à pénétrer dans la tête de fixation pour la bloquer dans le logement du panneau frontal (10).
摘要:
Metallischer Einsatz zum Einbetten in eine Aufnahmebohrung eines Aufnahmeteils aus einem Werkstoff niedrigerer Festigkeit. Der Einsatz hat einen Grundkörper (2) in Form mehrerer koaxial übereinander angeordneter Kegelstümpfe (4a-d) und einen Einstichabschnitt (7), der sich an den in Ausziehrichtung (x) letzten Kegelstumpf (4d) anschließt. In dem Einstichabschnitt sind mindestens zwei radial verlaufende Rippen (8) zum Erhöhen des Verdrehwiderstandes angeordnet. Der Einsatz hat daher trotz eines vergleichsweise geringen Einpreßwiderstandes sowohl einen hohen Ausziehwiderstand wie auch einen hohen Verdrehwiderstand.

A threaded insert comprises an externally threaded housing (12) with an internally unthreaded floating nut (17) therein. Diametrically spaced ears (50) on the nut are engaged in diametrically spaced grooves in the housing, respectively, to limit relative rotation between the nut and the housing yet permit radial movement of the nut relative to the housing. A single split ring (40) locks the nut into the housing.
