摘要： A pre-formed concrete section comprising a deck and first and second legs extending from the deck. The deck includes a first side, a second, and a width extending between the first and second sides. The deck also includes a top surface, a bottom surface, and a thickness extending between the top and bottom surfaces. The distance from the first leg to the second leg is more than two times greater than the distance from the first side to the first leg. The width of the deck is more than four times greater than the distance from the first side to the first leg. The thickness of the deck decreases as the deck extends outwardly from the first leg toward the first side. The thickness of the deck decreases as deck extends outwardly from the second leg toward the second side. A platform including multiple sections includes unevenly spaced legs.

摘要： A composite, prestressed structural member and methods of forming such a member. The apparatus includes a plurality of longitudinally extending girders and a deck unit attached thereto. The deck unit may comprise a plurality of adjacent composite units disposed on the girders, with each composite unit having a plurality of beams with a molded deck portion formed thereabove. In one method, the structure is formed by positioning the girders on a construction support adjacent to a center portion of the girders such that the free ends of the girders cantilever and deflect downwardly. The beams of the composite units are attached to the girders in this construction position. In a second method, the structure is formed by positioning the girders in their normal operating position such that they are supported on opposite ends, and then providing a support for a center portion of the girders such that at least a portion of the lower edges of the girders are placed in compression. The deck unit may alternatively comprise one or more molded deck sections connected to the girders by shear connectors. In a third method of construction, these molded deck sections are formed while the girders are in their normal operating position supported on opposite ends while also supporting a center portion of the girders. The moldable material is allowed to harden while so supported.

摘要： A composite, prestressed structural member, such as a bridge unit and methods of forming such a member. The apparatus includes a plurality of longitudinally extending girders which are transversely spaced and a plurality of adjacent composite units disposed on the girders. Each composite unit has a plurality of beams with a molded deck portion formed thereabove. The beams are positioned transversely with respect to the girders and attached thereto. Additional, longitudinal beams are disposed between the transversely extending beams over the girders. The longitudinal beams are attached to the girders and by connectors to the molded deck. The structure is formed by positioning the girders on a construction support adjacent to a center portion of the girders such that the free ends of the girders cantilever and deflect downwardly. The beams of the composite units are attached to the girders in this construction position. Any gaps between adjacent composite units are filled with a non-shrink, high strength grout. When moved to an operating position wherein opposite ends of the girders are supported, the natural deflection of the unit due to its weight imparts a compressive prestress longitudinally in the molded deck units. Each molded deck unit may be formed such that it is also transversely prestressed.

摘要： Bridge systems and methods for constructing bridges having overhang surfaces employing generally rectangular, precast, prestressed concrete panels. One method includes delivering a plurality of generally rectangular, precast, prestressed concrete panels to an installation site, and delivering one or more support beams to the installation site, each support beam having a support and a base. The concrete panels are positioned on the supports of the one or more support beams with an overhang panel section and a traffic panel section. The concrete panels are then connected to the support beams by positioning steel reinforcement in block outs or voids, pouring unsolidified concrete into the voids, and curing the unsolidified concrete to form an overhang traffic surface. Bridges constructed employing the precast, prestressed concrete panels and methods. Other bridge systems employ prestressed concrete L-walls and double-T members, where weight-bearing L-walls have pockets for webs of the double-T members.

摘要： “A method for producing a construction section of a deck slab for a bridge includes the following operations: producing a bottom layer composed of a segment and having cross beams, which are arranged in the transverse direction in regard to the longitudinal axis of the longitudinal bridge girder, from reinforced concrete; transporting the bottom layer having the cross beams for a construction section of the deck slab using a conveyor device from an assembly site to an installation site and lowering it into the installation position; producing a top concrete layer for a construction section of the deck slab on the bottom layer; removing the bottom layer having the cross beams for a construction section of the deck slab from the conveyor device and moving the conveyor device away from the installation site.”
