Abstract

Boulon expansible du type comprenant deux douilles fendues et deux cônes en assurant l'expansion. Selon l'invention, les douilles Il et 12, en acier non trempé, sont identiques et fendues sur moins de 50 % de leur longueur. L'expansion de Il est assurée par un cône fileté 16 se vissant au boulon 10, et celle de 12 par un cône 17 coulissant entre les deux douilles. Le diamètre extérieur des douilles est assez petit pour faciliter leur introduction directe dans un trou sans demontage. L'invention s'applique aux ancrages dans des murs en béton poreux ou autre matériau relativement tendre.Expanding bolt of the type comprising two slotted sockets and two cones ensuring expansion. According to the invention, the bushings II and 12, made of unhardened steel, are identical and split over less than 50% of their length. The expansion of II is ensured by a threaded cone 16 screwed on to the bolt 10, and that of 12 by a cone 17 sliding between the two bushes. The outer diameter of the bushes is small enough to facilitate their direct introduction into a hole without disassembly. The invention applies to anchors in walls made of porous concrete or other relatively soft material.
