Abstract
A sleeve (20) for centering fasteners during the assembly of components such as facade elements on the substructure of a building envelope includes a sleeve body (23) and a connection bracket (25). The sleeve body (23) has a plurality of sleeve elements (21, 22) which are grouped around a central center axis A and are spaced apart from each other by gaps running in the sleeve longitudinal direction. At least a first (21) and a second (22) sleeve piece are connected to each other at an axial longitudinal end of the sleeve body (23) by a separable connection bracket (25), preferably the connection bracket is separable via predetermined breaking points. Such a sleeve is used in the construction of facades, wherein it is inserted into a pilot hole of a facade element, the connection bracket is broken off and a fastener is inserted into the sleeve. Driving the fastener centers the fastener in the sleeve and the sleeve is removed from the pilot hole.
