| 014003000 | TRUSS | 9 |
| 014004000 | Arrangement | 8 |
| 20090183321 | Flared leg precast concrete bridge system - A concrete building system includes a set of parallel spaced apart strip footers and one or more precast concrete sections supported by the footers in a predetermined alignment. Each precast concrete section has a top slab integrally connected to a pair of equally flared legs. Each leg depends from an end of the top slab at an effective flare angle to form a corner. The precast section includes haunch sections formed between the top slab and each leg resulting in a corner thickness greater than the uniform thickness of the angled leg to which it is integrally formed and the top member. The length of the effective span of each section varies between 60 and 90 percent of the distance between the bottom-of-leg span. The sections can be used to construct bridges, culverts, underground storage units, fluid detention units and dam structures. | 07-23-2009 |
| 20110047722 | Hoop Truss Bridge - A tubular truss bridge structure comprising a plurality of interconnected angularly interrelated hoop shaped cross members having a common longitudinal central axis and forming alternately inverted triangular spaces along the length of the tubular truss and having a plurality of spaced apart longitudinal stringer members that interconnect the hoop shaped cross members. | 03-03-2011 |
| 20150354151 | LATTICE TRUSS - Lattice truss comprising: two upper beams ( | 12-10-2015 |

| 20160376754 | MOBILE CROSSING STRUCTURE - A movable and dynamic work after construction linking two points separated by a natural or man-made obstacle, allows the permanent crossing of this obstacle. The work includes a deformable apron ( | 12-29-2016 |
| 014006000 | Deck | 4 |
| 20100017975 | Reinforced Mine Ventilation Device - A mine ventilation and bridge structure incorporating a bridge feature enabling a mine vehicle to cross over the structure. The structure comprises a pair of generally parallel and spaced-apart side walls defining opposing side walls and a plurality of elongate deck panels extending between the side walls. At least one deck panel of the plurality of deck panels is a reinforced bridge deck panel constructed to support the weight of a vehicle crossing over the mine ventilation and bridge structure. | 01-28-2010 |
| 20100043153 | Bridge structure - A bridge supports any desired loading capacity to cross rivers, ravines, highways, wetlands, and other areas where traffic or pedestrians conveniently access the opposite side. The structure is assembled in a number of ways at the bridge site, using smaller equipment and less time than is normally required. The prefabricated and trial fitted elements can be assembled at ground level and the structure can be launched on rollers across the area that is to be crossed, or can be assembled sequentially from one or both sides. The structure includes two or more box trusses supporting the bridge deck which is integrated into the structure. The upper portion of the trusses form the side barriers of the bridge and the deck with integrated cross members is fastened to the lower portion of the trusses, both of which are sized to accommodate the load bearing capacity of the traffic using the structure. | 02-25-2010 |
| 20140259463 | COMPOSITE ACTION SUPPORT STRUCTURES - A composite action support structure for a bridge or other civil infrastructure includes an elongate member made of a plastic material and providing load bearing capability. A cover plate is made of a plastic material and extends along at least a portion of the length of the elongate member. A lower surface of the cover plate is mated to the upper surface of the elongate member. A plurality of panels made of a plastic material are arranged at an angle to the cover plate, and a lower surface of each of the panels mates with an upper surface of the cover plate. The elongate member, the cover plate and the plurality of panels form a structural unit. The plastic materials used can include virgin plastic, thermoplastic, recycled thermoplastic composite, recycled structural composite, combinations thereof, and the like. | 09-18-2014 |
| 20150292168 | Deck - Provided is a deck, configured for supporting a carriageable surface, including first structural girders defining a support surface for the carriageable surface; at least one second structural girder configured to position itself on the opposite side to said carriageable surface in relation to the first structural girders; diagonal girders integrally connecting the first and said second structural girders to each other, defining, for the deck, a truss; said first and said second structural girders include a core in concrete material: and an external reinforcement partially cladding the core and made of metallic material. | 10-15-2015 |
