System for anchoring building elements

A system for anchoring building elements, such as building elements comprising at least one first and one second mutually plane-parallel building element sheets which are interconnected by means of a joint placed in edge areas of the building element in the form of a string of compliant and/or elastic material, wherein the anchoring system comprises a frame piece and an anchoring device connectable to the frame piece comprising an anchor and a gripper pivotally connected to the anchor which can be brought into engagement with the joint of the building element by pivoting when anchoring the building element in the frame piece, and wherein the anchor can be inserted into a channel running in the longitudinal direction of the frame piece, which is formed by two mutually opposite channel walls, a bottom segment and an opening mouthing in the upper side of the frame piece, wherein the anchor in inserted position in the channel can be fixed in position by means of one or more locking means which fix the anchor relative to the bottom segment in that one or more stop screws are supported in the anchor which, when tightened, are screwed out of the anchor for engagement with the bottom segment of the channel and which apply a force to the anchor directed towards tongues which define the opening of the channel in the upper side of the frame piece, with the bottom segment acting as a counter support.
