Abstract
A scaffolding construction used particularly for H-shaped frames. The postsf a frame are provided at one end with a bushing, of which the inner diameter is larger than the outer diameter of the post (1). The bushing is provided with a recess and a staggered groove lying opposite to the recess. The end of another post is provided with a pin (14) which can be fittingly received through the groove and recess (7) in bushing (5). During assembly the post is placed in a position, such that its pins (14) are inserted through the groove via the recesses. During the angular rotation of the post into its vertical position, the pins are guided by the grooves and supported by the recesses, so that the pins come to rest in the posts.
