| 20110131740 | ENERGY STORAGE BRIDGE - An energy storage bridge includes a plurality of bridge girders and a bridge deck. The bridge girders include multiple steel pipes for carrying loads and storing energy in a form of compressed air contained therein and a plurality of web plates. The bridge deck is disposed on top of the bridge girders and configured for loading live loads. The steel pipes are assembled in at least a row aligned vertically. Each web plate connects a row of the steel pipes at a center line separating the steel pipes into two halves. Alternatively, a steel pipe is connected by two webs at the two sides of the pipe. Each bridge girder forms an energy storage unit between two consecutive movement joints of the energy storage bridge. Every two consecutive storage units are joined by a high pressure flexible pipe to form a giant energy storage unit. Each energy storage unit is provided with inlet and outlet pipes to in-take compressed air from electric compressors driven by the grid power or by regenerated powers, and to release the compressed air to generate electricity. The bridge girders are disposed at a predetermined transverse spacing across the width of the bridge deck and configured for supporting the bridge deck as a roadway surface. | 06-09-2011 |
| 20130091640 | SUPPORT ELEMENT - Provided is a wood splitter having a support element, a first elongated element, a second elongated element, and wood splitting components. A support element may be a first elongated element and a second elongated element engaged to the first elongated element. The first elongated element may be subject to a first pre-stress load. The first pre-stress load may be a first moment. The second elongated element may be engaged to the first elongated element and may be subject to a second pre-stress load. Wood splitting components may be engaged with at least one of a first elongated element or a second elongated element, may be adapted to operate to split wood, and may be adapted to apply an operational load during operation to the first elongated element. The operational load may at least partially relax the first moment. | 04-18-2013 |
| 20160096696 | GAP BARRIER FOR DOCK LEVELERS - The present invention provides an apparatus for covering a gap that is adjacent a side of a dock plate, which apparatus includes an elongate member having a top surface and a bottom surface, a pin connected to the bottom surface, a tear-resistant material in contact with the bottom surface of the elongate member; and a means for maintaining the contact between the tear-resistant material and the bottom surface. | 04-07-2016 |

ARCH | 3 |
| 20090126129 | Precast Arch-Shaped Overfilled Structure - An arch structure for use in forming an overfilled structure includes at least one footing and at least one precast concrete bridge element forming an open bottom arch structure that is supported on the at least one footing. The arch structure has an upper portion, that may be formed by a first half-ellipse shape, and a lower portion, that may be formed by part of a second half-ellipse shape. The upper portion and lower portion meet at an elevation along the rise of the arch structure, and such elevation defines the largest span of the arch structure. The arch structure includes lower ends that come back inward toward each other, such that the span at the bottom of the arch structure is less than the largest span. | 05-21-2009 |
| 20140082864 | ABUTMENT STRUCTURES - Abutment and bridge designs include a bridge superstructure and abutment wherein the abutment has a vertical portion of a backwall that can be fixedly joined to the end face of the bridge superstructure without an interdisposed expansion joint. A downward facing surface of the bridge superstructure can be fixedly joined to an upward facing surface of the abutment, or alternatively, a bearing pad may be disposed therebetween. The abutment may further comprise a backwall made from a plurality of panels fixedly joined to a plurality of supporting piles. The abutments and bridge superstructure may be made substantially from composite materials including recycled structural composite and other thermoplastics. | 03-27-2014 |
| 20140041135 | PIPELINE CROSSING BRIDGE - A bridge comprising first and second ground contacting pads spaced apart from one another; plural ribs with lateral stabilizing elements between adjacent ribs of the plural ribs, each rib of the plural ribs being supported on both the first and second ground contacting pads and the ribs collectively forming an arch extending between the first and second ground contacting pads; and an upper crossing surface supported by the plural ribs. | 02-13-2014 |

EXPANSION DEVICE (E.G., BEARING PAD) | 2 |
| 20110252583 | ANTI-EXPANSION JOINT BRIDGE CONSTRUCTED THROUGH DETAILED SURVEY FOR BRIDGE - Disclosed herein is an anti-expansion joint bridge which eliminates an expansion joint structure from an upper structure thereof, and includes a plurality of slidable steel plates to cover a space between girders or floor slabs expanding and contracting on piers and asphalt concrete pavement on the steel plates, so that expansion and contraction of the girders occurring on the piers is prevented from affecting the pavement, thereby ensuring smooth travel of vehicles thereon. The anti-expansion joint bridge includes a pair of expandable/contractible girders separated from each other while constituting an upper structure of the bridge, a plurality of sliding plates overlapping each other on the girders while covering a gap between the girders, and an ascon part covering the pair of girders together with the sliding plates. | 10-20-2011 |
| 20120060306 | DAMAGE RESISTANT BRIDGE CONSTRUCTION - A bridge assembly is made up of stackable components that are arranged together to span substantially any size and type of geological formation. At least some of the bridge components can accommodate variations in their positioning relative to one another so that the bridge can still function after limited damage or shifting, or so that it can be readily repaired or rebuilt after being partially toppled. The bridge components can be pre-formed out of concrete, and can typically be assembled using primarily unskilled labor. | 03-15-2012 |

TRUSS AND ARCH | 1 |
| 20100281632 | Tunable Load Sharing Arch Bridge - A method and apparatus for adjusting the live and dead load balance between the arches of an arch bridge and the truss girder that supports the bridge deck. The method is achieved by providing hanger rods disposed between the arches and the top chords of the truss girder whose compression may be adjusted. In which the arch truss counter act the compression in the top chord of the truss. This interaction adds to the strength and safety of both elements of the structure. With this interaction there are no critical members which can cause catastrophic failure of the bridge by failing. By combining two of these bridges side by side, and then connected with the lateral members, both at top and bottom chord of trusses, it is possible to carry vehicular, train, and pedestrian lanes separated and accommodated with safety; all without a critical member. | 11-11-2010 |
