Abstract

1416298 Lattice girder MOLYNEUX ENG CO Ltd 2 Nov 1972 [15 Oct 1971 5 Nov 1971] 47987/71 and 51463/71 Heading E1K In a lattice girder having upper and lower booms each formed of two parallel, spaced, elongate members 14, 14 and 15, 15 respectively, the transverse members 16 have at each end 17, 18 either flat portions or flanges 7 which are wider than the central part of the member and which enter between and are welded to the elongate members 14 and 15. The transverse members may be of L, U or I section with the flanges bent outwardly at each end to form the flanges 7. Alternatively, they may be tubular having their ends flattened and welded between the elongate members 14, 15, Figures 8-11 and 12 (not shown). The elongate members 14, 15 of the booms may be tubular. The edges of the flanges 7 at the weld points preferably lie on a common plane containing the neutral axis of the transverse member. The girder may be a roof truss, the upper boom having a ridge point.
