The bent sections are provided with holes at specific intervals from each other along the height of the wall panel. When two panels are placed side by side so that the L-section of one panel is fitted against the Z-section of another panel, the holes are positioned opposite one another. A U-shaped tongue strip is fitted against the L-section of the panel, the tongue strip being provided with tongues shaped and dimensioned so that the tongues pass through the holes of the side edges of both panels. A U-shaped wedge strip is fitted against the Z-section of the panel, the wedge strip being provided with holes shaped and dimensioned so that the tongues pass through the holes. The panels attach to each other when the wedge strip is knocked downwards. |
