Bracket-style support element for curtain facades on building walls

Claim 1

A bracket-style support element for curtain facades on building walls, said support element comprising: a plurality of grouting anchors adapted to be inserted in predrilled blind holes in the building wall, with the blind holes being arranged horizontally adjacent to one another and spaced in pairs at equal intervals, each of said grouting anchors including a hollow anchoring bolt having a central channel for accommodating the grouting material; a barbed disc provided at an insertion end of each of said anchoring bolts, each of said anchoring bolts including at least one outlet opening for enabling a discharge of the grouting material; a grouting sleeve provided for each grouting anchor and surrounding the anchoring bolt; sealing means provided at a forward end of the anchoring bolt so as to hold the respective grouting sleeves, said sealing means being disposed with an inwardly delimiting longitudinal segment of the anchoring bolt and grouting sleeve in a forward area of the opening of the blind hole in the building wall whereby, when the grouting material is forced into the anchoring bolt, a segment of the grouting sleeve located forwardly of the opening expands and an anchoring bulb is formed which fits around an opening of the blind hole and abuts a front of the building wall and the grouting sleeve is laterally expanded in the blind hole in the masonry wall forming a grouting material plug with internal anchoring projections, and said barbed disc is anchored in the blind hole by the grouting material plug; said support element further comprising: an L-shaped rail associated with each pair of grouting anchors, said L-shaped rail having a vertical leg from which the fastened grouting anchors project, said L-shaped rail including a horizontal support leg extending away from the building wall; and a joint tube adapted to be inserted between adjacent curtain facades of the building wall, said joint tube being disposed at an underside of the horizontal leg support of the L-shaped rail, said joint tube being provided with an injection opening for enabling an injection of mortar whereby a plurality of curtain facades, joint tubes, and L-shaped rails produce a continuous supporting second masonry wall which is joined by said grouting anchors with the original masonry wall forming a statically stable double wall.
