Abstract
An anchoring means for anchoring by a bonding mass in a drilled hole in a concrete part or the like has a threaded bolt with a reduced portion and an expansion cone followed by a head part, forming at the same time a stop shoulder. Over the reduced portion and expansion cone is slipped an anchoring sleeve which is provided on its outer surface with a plurality of longitudinal grooves. By the longitudinal grooves and the elasticity of the anchoring sleeve consisting of plastics material, the possibility is obtained of compensating for the enlargement of the drilled hole when a crack forms, thus making it possible for the anchoring means to be used in the zone subject to tensile forces.
Claims11
An anchoring device for anchoring by a bonding mass in a drilled hole in a concrete part or the like, the anchoring device comprising a threaded bolt having an end facing a drilled hole and being provided with an expansion cone widening out to said end;
- an anchoring sleeve surrounding said threaded bolt and expandable by said expansion cone;
- a head part provided with a wedge-like point and following said expansion cone so as to form at the same time a stop shoulder, said threaded bolt starting from a smallest diameter of said expansion cone having a portion of reduced diameter which extends over a part of a length of said threaded bolt, said anchoring sleeve being arranged on said portion and extending from said stop shoulder of said head part to an end of said portion and is composed of plastic material, said anchoring sleeve having also an outer surface which is provided with longitudinal grooves.
