ELONGATE PIPE-BASED TEMPORARY BRIDGE FOR SUPPORTING HEAVY LOADS

摘要

A temporary bridge for supporting heavy loads includes elongate hollow cylinders. A first rigid flat plate is horizontally disposed in overlying relation to each hollow cylinder and a second rigid flat plate is horizontally disposed in underlying relation to each hollow cylinder. Stress-distributing strengthening members formed by a pair of legs that are angularly disposed with respect to one another are circumferentially positioned about each hollow cylinder and the respective free ends of the legs are secured to their associated rigid flat plates. A key extends from a first end of each hollow cylinder and a mating socket is formed in a second end of each hollow cylinder to facilitate end-to-end interconnection of a plurality of hollow cylinders. Further embodiments include longitudinally-disposed timber mats, pedestrian walkways and curvature-creating members so that the bridge may follow a non-linear path of travel.

主权项

1. A temporary bridge, comprising:
an elongate hollow cylinder having a longitudinal axis of symmetry; a first pair of stress-distributing strengthening members mounted to said hollow cylinder on opposite sides of a vertical plane that bisects said hollow cylinder; a second pair of stress-distributing strengthening members mounted to said hollow cylinder on opposite sides of a vertical plane that bisects said hollow cylinder; said first and second pairs of strengthening members disposed on opposite sides of a horizontal plane that bisects said hollow cylinder; each of said strengthening members being generally “L”-shaped and being formed by legs that are disposed in angular relation to one another; a first flat plate of rectangular configuration and rigid construction overlying said hollow cylinder; a second flat plate of rectangular configuration and rigid construction underlying said hollow cylinder; each of the legs of the upper pair of strengthening having a free end secured to an underside of said first flat plate; each of the legs of the lower pair of strengthening having a free end secured to a top side of said second flat plate; said first flat plate held in a horizontal plane by said upper strengthening members; and said second flat plate held in a horizontal plane by said lower strengthening members.
