Welded lattice girder struts nodal joint - has one strut end bent along chord gravity line while other runs straight

摘要

Ends of two individual struts are directly joined to chords, on lattice girders with zigzag or saw-tooth strutting. The end (49) of one of the two struts (41,42) is bent back (48) with the chord's (40) gravity line (46) at the intersection (43) of its own gravity line (44), and continues straight along it. The end of the other, running straight, meets these two gravity lines. The meeting place (47) of the two struts, and the end of the continued first strut, are welded to each other and to the chord structure. The ends may also be welded to the chord structure in their neck area. This permits construction of nodal connections regardless of chord profile height, with adequate weld seam length.
