Abstract
A modular bridge comprising two end modules adapted for connection to respective end footings, a plurality of side railings adapted for modular interconnection in two parallel rows between the end modules, adjacent ones of the side railings being connected via interlocking splices, a plurality of floor beams arranged orthogonally between the two rows of side railings, and a structural connection for securing respective ones of the floor beams to corresponding ones of the side railings. The interlocking splices preferably each comprise a plurality of ribs disposed within respective ends of adjacent ones of the side railings for defining respective slots therebetween, a plurality of plates adapted for insertion into the respective slots, and apparatus for securing the plurality of plates within the respective slots.
Claims10
A splice for connecting two ends of hollow tubing, comprising:
- (a) a plurality of ribs within each said two ends of hollow tubing for defining respective slots therewithin:
- (b) a plurality of plates adapted for insertion into said slots within each said two ends of hollow tubing;
- and
- (c) means for securing said plurality of plates within said respective slots, whereby said plurality of plates form an arrangement of interlocking fingers relative to said respective slots for providing a rigid connection between said two ends of hollow tubing.
A modular bridge comprising:
- (a) two end modules adapted for connection to respective end footings;
- (b) a plurality of side railings adapted for modular interconnection in two parallel rows between said end modules;
- adjacent ones of said side railings being connected via respective interlocking splices;
- (c) a plurality of floor beams arranged orthogonally between said two rows of side railings;
- and
- (d) means for connecting respective ones of said floor beams to corresponding ones of said side railings, each said means for connecting comprising at least one horizontal support member extending from each said adjacent ones of said side railings at said interlocking splice for supporting a corresponding one of said floor beams thereacross, whereby each said side railings support a portion of the load of said corresponding floor beam along a centre line at said respective interlocking splices yielding high lateral stability of said floor beam.
