Definitions

  • the invention has for its object to improve a composite anchor according to the preamble of claim 1 such that handling is improved, fewer parts are required, no complex special tool is required, the bolt diameter can be equal to the diameter of the composite anchor, the suitability for the tensile zone of reinforced concrete structures (in particular ceilings) is fulfilled, the suitability is also given for peripheral zones and short waiting times have to be observed before the composite anchor can be fully loaded.
  • the composite anchor has a sleeve-shaped housing with a receiving space extending in the longitudinal direction, from which outflow channels lead radially outwards.
  • the longitudinal direction is understood to mean the axial direction of the composite anchor.
  • the described embodiment has an impact piece 3.
  • the triggering of the ignition element which can also be arranged outside the generator 2, can, for. B. thermally or by laser energy.

Abstract

L'invention concerne une tige d'ancrage composite pourvue d'une masse (5) durcissable servant à la fixer dans le trou foré (6). Entre autre, pour améliorer la manipulation et réduire le nombre de pièces, il est proposé qu'un générateur pyrotechnique de chaleur et de poussée (2) soit placé dans la tige d'ancrage composite, ce générateur, lors de l'allumage de la charge pyrotechnique (7), chauffant la masse (5) durcissable et la poussant dans le trou foré (6).
