1. A facade anchor for anchoring a facade to a main wall, the facade being arranged at a distance in front of the main wall and the facade and main wall having aligned bores;

  • the facade anchor comprising;

    an elongate connecting element in the form of a thin-walled and corrosion-resistant metallic anchoring tube for insertion into aligned bores of the main wall and the facade,the tube forming a mortar injection pipe, the front end of which is open to act as an outlet opening, said tube having a number of diametrically disposed outlet openings along its rear portion and leading into the facade bore through which mortar may be discharged to form transverse webs extending from the wall of the facade bore through said diametral openings, the anchoring tube being reinforced at several places along its length by diametrically arranged pairs of transverse identations which run parallel to the circumference to improve the tensile and flexural strength so that the anchoring tube has a limited resiliency allowing relative movements of the facade with respect to the main wall; and

    plastic material bushings for centrally positioning the anchoring tube within said bores, each of the bushings having radially outwardly extending resilient annular lamellae for sealing the tube within the bores.
