    (54) Coupling between two sandwich panels, and modular building system based thereon


    (57) The invention relates to a coupling between two sandwich panels (1, 2), each comprising: an insulating layer (3) being covered on its one side with a first metal plate (4) and on its other side with a second metal plate (5), each of the panels (1,2) having a prismatic connecting edge (6, 7) for coupling by means of connecting means (13) another like panel (1, 2) to said connecting edge. It is a purpose of the invention to design a coupling of this type in such a way that interior ventilation and vapour transport in the space bounded by the plates is effectively stimulated, whilst nevertheless the properties as e.g. a partition of two coupled panels is not adversely affected.
