<p>The present invention solves a problem of building geometry in a system to assemble and shut exclusively by jointing the six walls of a box parallelepiped built up with at least seven plates, so:•the plates are divided in a first group of six, named primary, each one provided with a couple of grooves, and in a second group of the remaining plates, named secondary, not necessarily grooved;•the walls of the structure are divided in two types: single walls, composed by only one primary plate: multiple walls, composed by one primary plate and at least one secondary plate;•the structure, which must have at least one multiple wall, is assembled and shut jointing together first the six primary plates and then introducing at least one of the secondary plates. The system is suitable to build countless artefacts.</p> |
