<p>The construction has four- to ten angular profiles whose side walls (1) are arranged on a base plate (3) by horizontal planks (2). The side walls have abutting edges, which are held together with a perpendicularly arranged edge plate from outside. The planks are connected with each other by groove-spring connections. The edge plate is bent corresponding to an angle of the side walls, where the edge plate includes an outwardly aligned bending at perpendicularly running edges. The edge plate is connected to the side walls by a continuously tensioning screw.</p> |
