<p>The invention concerns a method for making a three-dimensional rigid structure by wedging from at least an initial flat panel. A drill runs along and cuts the panel producing one or more rectangular recesses to obtain ladder-type frames provided with cut-out edges and side panels provided with notches. The notches and cut-out edges with rounded bases are designed to co-operate and enable a side panel to be wedged between two parallel ladder-type frames provided with a floor panel, the latter being obtained separately. The floor panel is provided with four notches designed to be wedged in the edge of four vertical posts of two ladder-type frames arranged parallel.</p> |
