Connecting element for wall components

A connecting element for connecting at least two wall components, the connecting element comprising:

• a component having a double-U shape punched and molded out of a sheet metal part, said double-U shaped component formed from four surface parts which correspond to a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant and a shared web, said double-U shaped component being comprised of two offset and opposing U-profiles having the shared web which is provided with a channel-shaped depression arranged symmetrically in the shared web,
• wherein each said U-profiles consists of two respective legs spaced apart by a portion of said web, and which extend from the web in a perpendicular direction and in a direction 180 degrees away from each other,
• the component formed from a flat, punched part made out of sheet steel having a geometric contour, which contains two punched sections spaced apart from each other and running on a continuous line from a respective outer edge to a middle of the punched part, which punched sections are arranged centrally relative to the contour, and whose distance from each other forms a web width corresponding to the thickness of a wall component,
• wherein the web width runs in a perpendicular direction to the punched sections, forming the web,
• wherein at least one punched hole is arranged in each of the first quadrant, second quadrant, third quadrant, and fourth quadrant,
• wherein the punched holes located in the second quadrant and the third quadrant are provided with a recess, and
• wherein the recess of the punched holes in the second quadrant is arranged on the front side, and the recess of the punched holes in the third quadrant is arranged on the rear side of the punched part so that in a ready bent state, the recesses of the punched holes in the second quadrant and the third quadrant point from an operating side of a U-profile toward an inner side;
• wherein at least one of the punched holes provided with a recess together with another of at least one of the punched holes without recesses in the ready bent state form a respective pair of punched holes, which in the U-shaped profile stand perpendicular and spaced parallel part from each other by the web, and have a shared center line.
