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 making a prefabricated, prestressed module includes arranging one or more steel beams atop a supporting formwork element in a direction transverse to the supporting formwork element and arranging one or more precast deck elements across the one or more steel beams to create a substantially continuous surface. The one or more precast deck elements have pockets for receiving connectors that protrude from the one or more steel beams. The method also includes arranging the supporting formwork element to allow the one or more steel beams to bend into a cambered shape to impart compressive stresses to a bottom flange of the one or more steel beams and tension stresses to a top flange of the one or more steel beams and inserting grout into the pockets to hold the cambered shape and to bond the one or more precast deck elements to the connectors and the top flange.

摘要： A bridge assembly includes a plurality of platform members which may be secured to support beams via individual platform chassis which are configured to allow tool-less attachment bolt heads thereto. A plurality of specially configured clamps are attached to the free ends of the bolts and the clamps are used to secure the platform members to the platform chassis. The platform chassis are each secured to the outer support beams via L-brackets that are mounted between the chassis and support beams. The support beams include flanged channels wherein the heads of a plurality of bolts may be attached without the need for tools. The platform members may be laid in either a parallel or perpendicular orientation with respect to the outer support beams with two different clamp styles being used depending on the orientation selected.

摘要： An upper structure for a bridge includes a coping placed on the top of a pier, and girders held by the coping, wherein the coping has girder holding grooves. The girders are installed continuously without using bridge bearings, thereby reducing the construction cost. The coping and the girders behave in an integrated state, thereby realizing improved structural efficiency. The girders are held by being fitted into the grooves, so the coping is not excessively exposed to the outside, thereby realizing a good appearance of the bridge. The girders and the coping are thy-joined together in a prestressed state using prestressed steel strands, so that the strength of the girders and the resistance to a negative bending moment can be increased. Further, the girders and the coping can be integrated with each other without being processed by site work, thereby realizing improved structural efficiency and reducing the construction period.
摘要翻译：用于桥梁的上部结构包括放置在码头顶部的应力和通过应力保持的桁架，其中所述应力具有梁保持槽。大梁连续安装而不使用桥式轴承，从而降低施工成本。应对和大梁行为一体，从而提高结构效率。大梁通过嵌入槽中保持，因此不会过度暴露于外部，从而实现了桥梁的良好外观。在预应力状态下，使用预应力钢绞线将桁架和应力器连接在一起，从而可以提高桁材的强度和抵抗负弯矩的能力。此外，桁架和应对可以彼此结合，而不必通过现场工作进行处理，从而实现了改进的结构效率并缩短了施工周期。

摘要： A bridge replacement method is disclosed. The bridge includes a deck supported by a pair of abutments, each abutment having wing walls. The deck is removed, footings are cast in holes dug behind each abutment and a pier is provided on each footing. Substantially parallel and coplanar cambered beams are provided. Each beam spans between and is supported by the piers. A brace assembly reinforces the beam camber. On each adjacent pair of beams, precast deck elements are placed, such that each element of said plurality spans the beam pair, to define at least transverse gaps between the elements and put the upper surfaces of the elements in compression in a transverse direction. The gaps are grouted. After grout curing, the brace is adjusted to reduce the beam camber and cause the upper surface of the elements to also be put into compression in a direction parallel to the beams.

摘要： A steel structure including pre-stressing brackets for improving load-carrying capacity and serviceability comprises: a steel girder; a plurality of connecting brackets connected to the bottom surface of the steel girder spaced and apart from one; and a cover plate connected to the bottom surfaces of the connecting brackets. Since the cover plate is installed regardless of the connecting portion of the steel girder, pre-stressing section can be consecutively formed therefore pre-stress effect is improved. Moreover, since the connecting brackets space the cover plate a constant distance from the steel girder, the moment of inertia is increased so the span of a bridge might be increased.
