Tubular structure with internal couplings - has coupling members engaging in hollow cores in individual components

摘要

The tubular structure has internal couplings between the individual components (1,4), these each having a hollow core (2). The cores accommodate a coupling member (5) assembled from pin-type components, forming an invisible joint between the tubular components. The coupling unit is suitable for various building construction units, e.g. false ceilings, window frames, corner connections etc. The tubular structure of aluminium may be of spider shape, providing facility for compound connections.
