Modular system from cube-similar modules (1.3). The sides consist of laminar components. These two dimensional elements are connected by a special link. The edges of the components are umgefalzt and by an u-shaped clamping track are connected inward. This becomes secured by two angeformte noses at the rebates (1, 4, 1, 5). With the connection system both the cube-similar modules are built up, and connected with the adjacent module. So walls in arbitrary height and width can be built up. The form of the finished wall is determined by the forms of the individual two dimensional elements (1, 6, 1, 7). Also components can be omitted, so that specialized-like gaps result.
