| 摘要 |
The invention relates to a scaffolding tube (10) of scaffolding, having a tube axis (A), which extends from a first axial tube end (12) to an opposite second axial tube end (14), a receiving segment (16) provided at the first axial tube end (12), and an insertion segment (18), which is provided at the second axial tube end (14) and which has a cross-section that is reduced with respect to the receiving segment (16) and which ends with a radial step (22), which forms a bearing surface (24) directed toward the insertion segment (18), wherein the inside diameter (du) of the receiving segment (16) is greater than the outside diameter (d2,a) of the insertion segment (18), so that an adjacent scaffolding tube (10) having an identical insertion segment (18) can be inserted into the receiving segment (16). The receiving segment (16) has exactly one positioning groove (26) at the first axial tube end (12), which positioning groove is discontinuous or continuous in a circumferential direction and reduces the inside diameter (d1,i,) of the receiving segment (16) and defines the minimum inside diameter (d1,i,min) of the receiving segment (16). Alternatively or additionally, a tube wall (34) of the scaffolding tube (10) has a maximum wall thickness (smax) at the first axial tube end (12) and otherwise has a smaller wall thickness (s). |
