Abstract:
A method for embedding connection elements in a wall comprising the steps offurnishing a mold surface;disposing connection elements in a rear part of the mold surface, wherein the connection elements exhibit in each case a punch-like section having a jacket;placing a wall against the mold surface and said wall having a face disposed remote relative to the mold surface and a face disposed neighboring to the mold surface;generating a high pressure acting on the face disposed remote relative to the mold surface for pressing the wall and the face disposed neighboring to the mold surface against the mold surface;piercing the wall pressed against the mold surface with a moving punch-like section subjected to a shearing force, wherein the shearing force acts in a direction opposing a pressure force of the high pressure acting on the face of the wall disposed remote relative to the mold surface;friction-fastening the punch-like section in the wall after the wall is pierced by the punch-like section.
