ABSTRACT OF THE DISCLOSURE Tubular bars are connected to form room or open space framing by screw bolts with heads at their ends to connect the bars with intersecting members. Screw bolts with heads are supported in the end areas of the bars to be rotatable and axially movable. Their outward axial movement in each case is limited by a limiting boss in the end area of each bar. The limiting boss for the screw bolts with heads is formed by shaping of the end segments of the tubular bars in their hollow space. In tubular bars with tapered, truncated conical end segments, the head of the screw bolts can be welded against the inside wall of these end segments, when it is of correspondingly fitted truncated conical shape.
