<p>The tubular profile construction has an accommodating unit (2a,2b) for mounting a scaffolding bar (3a), where the round shape of a tubular profile (1a,1b,1c) forms a pivot point in an angled installation of the stairs. A handrail (4) of the railing is fixed at the top of the profile. Multiple components are connected into a complete stair stringer, where the handrail is also interconnected. A wedge lock connection (5) is obtained from the scaffolding. A statically load-bearing connection of the handrail is formed through an internal pipe connector (6) in the handrail.</p> |
