<p>The method involves providing cavities with a rear wall (10) in a defined depth. An array of punched holes is drilled at an angle in a side bolster (11) in a defined distance such that the punched holes exactly overlap in side edges that are adjoined to each other. Bolts (3) are inserted in the punched holes, where the bolts are adjoined to the rear wall. A profiled board (2) with hole is plunged at the bolts, where upper and lower bolts include transverse holes in which a fastening unit is inserted from top or bottom along the two adjacent cavities. An independent claim is also included for a bolt for connecting profiled boards, comprising a rear wall.</p> |
