The invention relates to a pipe connection structure comprising a first component (2) and a second component (5). The first component (2) has a pipe portion (21) and the second component (5) is equipped with a pipe portion (51) and a pipe connector (7) which extends from a longitudinal end of the pipe portion (51) and can be arranged in the pipe portion (21) of the first component (2). The pipe portion (21) of the first component (2) and the pipe portion (51) of the second component (5) lie axially against each other when the pipe connector (7) of the second component (5) is arranged in the pipe portion (21) of the first component (2). The pipe connector (7) of the second component (5) is equipped with an actuatable locking clamping mechanism, which locking clamping mechanism of the pipe connector (7) of the second component (5) is designed to lock and clamp the pipe portion (21) of the first component (2) and the pipe portion (51) of the second component (5) together when the locking clamping mechanism is actuated while the pipe connector (7) of the second component (5) is arranged in the pipe portion (21) of the first component (2).

A crossmember (3) comprises an elongate rod portion (31) and two latching claws (32). The rod portion (31) has a central longitudinal axis, a first longitudinal end and a second longitudinal end substantially opposite the first longitudinal end. The first latching claw (32) is arranged at the first longitudinal end of the rod portion (31) and the second latching claw (32) is arranged at the second longitudinal end of the rod portion (31). The first latching claw (32) and the second latching claw (32) each comprise a gripping portion (321) shaped to correspond to a rod-shaped element (22, 31, 52) and are designed to be mounted on the rod-shaped element (22, 31, 52) without tools. The gripping portion (321) of the first latching claw (32) is offset from the gripping portion (321) of the second latching claw (32) with respect to the central longitudinal axis of the rod portion (31).

A scaffold includes first and second ladder frames. Each ladder frame includes first and second vertical supports, and first and second horizontal supports mounted to the vertical supports. The first horizontal support is formed of tubular material, and has a base or central section and an asymmetric flattened end section. The end section is mounted to the first vertical support. The central section has a top centerline and a bottom centerline. The end section has a vertically elongated cross section compared to the central section. A top of the end section aligns with the top centerline of the central section; and a bottom of the end section is disposed below the bottom centerline of the central section. Related methods and tools are also disclosed.
