Abstract

989,632. Elevated footways. J. W. DARK. June 14, 1962 [June 16, 1961], No. 21811/61. Heading E1G. An elevated footway system includes prefabricated cantilever support units extending above and transversely of a road and supporting prefabricated footway units. As shown, decking plates 2, preferably of sheet metal, are mounted on the horizontal arms 3<SP>1</SP> of support units 6. The transverse angle of the footway can be varied by adjusting a tension rod 10 connected to the arm and to the base 8 of the support unit. The base 8 rests on a concrete raft 7 or it may be omitted in which case the upright member 4 of the unit 6 has an intregral ground anchor at its lower end. Adjustable bracing wires 32 interconnect adjacent units 6. The plates 2 are strengthened by ribs 12-14, the latter being hollow and forming a drainage channel. The footway is intended to be located against a building and has a safety wall 15 on its outer side carrying a hand rail 16 and litter bin 17. A downward extending flange 18 of the plate 2 normally abuts against the wall of an adjacent building but to increase the width of the footway it may have an extension plate 19 secured to it. A roof 27 is supported on frame members 34. In an alternative embodiment, (not shown) windowed panels are secured to the hand rail and to a fixed canopy mounted on the wall of the adjacent building. Footways on opposite sides of a road may be linked by bridge units.
