摘要

Addition to Patent No. 84 12 229 relating to an assembly node for planar or oblique cross-linked space structures and members for joining onto the node. The invention, which the present addition constitutes, relates to a device for angularly positioning the structural bars at a position which was predetermined when the node was manufactured; this device is composed of a ring 5 built into a nut 6 and having a projection 4 penetrating, when the nut is tightened, into the drilling 3 of the oblong holes 2. This ring 5 may be capable of retracting in a chamber 8 and relaxing under the action of a spring 9 when the projection 4 is located opposite the drilling 3. IMAGE
