System for mounting building elements

A system for mounting 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 mounting system comprises a frame piece and an anchoring device connectable to the frame piece comprising an anchor which can be fixed in the frame piece and a gripper connected to the anchor that can be brought into engagement with the joint when mounting the building element in the frame piece,

• wherein the frame piece is designed as a hollow profile, and
• wherein the frame piece is roll-formed from a sheet steel blank and provides a channel formed by bending and dimensioned for inserting the anchor wherein the channel has an opening in an upper side of the hollow profile and includes two channel walls running parallel in the longitudinal direction of the frame piece at a mutual distance and providing internal support beams standing between a bottom side of the frame piece and the opposite upper side of the frame piece, wherein the channel walls are designed and effective for absorbing tensile forces, and wherein the channel walls are interconnected by a bottom segment which runs parallel to the bottom side of the hollow profile.
