The application relates to a joint between a tube (2) and a rod or another tube (1) at an angle to the first-mentioned tube. …<??>This joint is provided with a ring (3,3a,3b) arranged about said rod or other tube (1) and is fastened thereto and split in at least one area. …<??>The two ends of said ring (3,3a,3b) border said joint or a gap and each pass on to a limb (4,5,12,13) being in parallel with another limb and with a plane traversing the longitudinal axis of the rod or other tube (1), and which, together with the other limb, forms a plug. …<??>This plug extends into the first-mentioned tube (2), it being screwed, with at least one screw bolt (7, 15), into a tapped hole (6) in the connecting element formed by the ring (3,3a,3b) and the limbs (4,5,12,13), and being adapted to be tightened and loosened to or from the first-mentioned tube (2) from the exterior for inserting said plug into the latter and for fastening the ring to the rod or other tube (1), one and other being characterized in that the ring (3,3a,3b) is a single or multipart clamping strip of sheet material, in that one of the two limbs (4,13) of the or each plug presents the tapped hole (6) for the bolt (7,15), in that the other limb (5,12) of the plug concerned and the wall of the first-mentioned tube (2) present, in an area directly adjacent the other limb (5, 12), a hole (9,21,10,19) passing at least a wrench (11) for turning the bolt (7,15) about its longitudinal axis, in that the tapped hole (6) and the two further holes (9,21,10,19) are coaxial and have their axes of revolution directed transversely to a plane traversing the longitudinal axis of the first-mentioned tube (2) and that of the rod or other tube (1), and in that the wall of the first-mentioned tube (2) forms a stop for the insertion end (16) of the bolt (7,15). …<??>The application further relates to a supporting bracket, it being characterized in that it consists of a strip having a part (24) with a shape bent into at least a half circle, fitting around said tube (2) of the carrying construction and a limb (25) being and directed adjacently radially outward, and in that the bent part (24) has, in an area diametrically opposite the limb (25), a radially inwardly directed bulging part or a lug (26) fitting in a hole of said tube or in a socket hole (27) in the head of the screw bolt (15) of the joint concerned. Application to the field of scaffolding, show window stands, display stands, ladders, steel furniture or other constructions composed of other rod-shaped elements. |
