STRUKTURELEMENTE UND ZUGEHÖRIGE TEILE

摘要

A structural member, e.g. a truss for erection of temporary structures, comprises a number of elongate elements (10-13) disposed in spaced generally parallel relationship to one another with transversely extending elements (14-23) therebetween, and an element extending longitudinally of the structural member has a formation (30) extending lengthwise of it for engagement by an attachment member which is to be retained to the longitudinally extending element at any of a range of positions therealong. The attachment member may provide for connection of a safety element to the structural member, and be freely movable therealong in use.
