Scaffolding post connection rosette with hollow embossments of reduced nominal thickness, and scaffolding subassembly

Abstract

The invention relates to a connecting rosette ( 10 ) for a scaffolding post ( 40 ), comprising a plurality of through recesses ( 16, 18 ) for the passage of coupling parts of scaffolding components ( 42 ) to be detachably connected to the connecting rosette ( 10 ), which are arranged at a distance from one another in the circumferential direction of the connecting rosette ( 10 ). The connection rosette has an upper and a lower side surface ( 12 a, 12 b ), which are designed plane-parallel and define a nominal thickness D N of the connection rosette. The connection rosette is provided with several hollow embossments ( 24 ) with projections ( 26 ) formed on only one of the two side faces ( 12 a, 12 b ) and corresponding recesses ( 28 ) formed on the respective other side face ( 12 a, 12 b ). The hollow embossments ( 24 ) are each arranged at a distance from the through recesses ( 16, 18 ) on a radial segment ( 30 ) of the connecting rosette ( 10 ), which extends in the radial direction from the inner edge ( 32 ) to the outer edge ( 22 ) of the connecting rosette ( 10 ) and by which one of the through recesses ( 16, 18 ) is bounded on each side. The invention further relates to a framework assembly ( 100 ).
