Extruded aluminum construction profile has at least one longitudinal groove, with structured dimensions, to take a conventional spline of an attached unit and allow a partial rotation around its longitudinal axis

摘要

The construction profile (10), especially of extruded aluminum, has at least one longitudinal groove (12) to hold at least one spline. The groove height is set so that the inserted spline can rotate at least partially around its longitudinal axis. The groove width is 9-10 mm, and the groove edges have inward projections. The profile has hollow zones (14) to carry media flows.
