817,993. Monorail railway tracks. ALWEGFORSCHUNG G.m.b.H. Oct. 5, 1955 [Oct. 5, 1954; Nov. 23, 1954 (2)], No. 28334/55. Class 104 (2), A monorail track for saddle-type vehicles 6 has upper and lower load carrying sections 1, 2 interconnected by transversely spaced smooth thin side panels or sheets 3 reinforced on their inner faces by structural members capable of absorbing bending and torsional forces of the same order of magnitude. In the arrangement shown in Fig. 2, the upper boxsection has a running surface 11 and side walls 14 formed from sheet bent to a V-shape or welded. The surface 11 is supported on L- section bars 12 welded to the underside thereof and to transverse beams 13 welded at their ends 18 to the side walls 14. The sloping ends 17 of the beams 13 are to eliminate stresses and reduce the welding length. The two outer L-section bars 12 are connected by welding to the walls 14 by plates 15. The edges of the plates 15 facing the outer L-section bars 12 are serrated. The transverse beams 13 are supported by L-section bars 16 welded to the beams 13 and the walls 14. In a modification shown in Fig. 4, the surface 11 is supported by a corrugated sheet 19 in turn supported on a lattice girder comprising two T-section members 20, 21 joined by cross-braces 22. The ends of the members 20, 21 are vertically spaced and supported by trough section members 24. The lower member 21 is supported by an L-section bar 23. The surface 11 is covered by a mix. ture of bitumen and broken stone or asphalt held in position by built-on transverse and longitudinal downwardly tapering ribs. In a modification shown in Fig. 5, the upper boxsection 1 comprises a centrifugally cast concrete slab, two longitudinal T-irons 16 connected by transverse girders 32, angle members 33 secured to the T-irons 16 and hoops welded to the members 33. The transverse girders 32 are welded to plates 38 welded to columns 36 and cross-braces 37 in turn attached at their lower ends to a cross-beam 41 joined by longitudinal channels 39 which on their outer flanges carry plates 40 serving as running surfaces for the lower side wheels of the vehicles. The side panels 3 at their upper edges are seam-welded to the T-irons 16 and to projecting ends of the plates 38 and at their lower ends are bent outwardly over the beams 41 and welded thereto. In the arrangement shown in Fig. 6, the members 25 are arranged in the form of an inverted triangle at the apex of which they are connected to an I-section girder forming the lower box-section 2. The upper box-section 1 is attached by anchors 27, 28 embedded or grouted in the concrete and welded to the members 25, 26 forming the supporting triangle. In a further modification, Fig. 7 (not shown), the anchors 28 are welded to a plate mounted between the base of the concrete slab and transverse girders 26.
