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： 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.

摘要： A form or a series of forms for forming the bridge diaphragm from concrete material includes one or more bottom walls having an inner surface thereof abutting a bottom surface of the diaphragm. There is at least a pair of side walls upstanding on the inner surface of the bottom wall or walls at a respective longitudinal edge thereof and has an inner surface thereof abutting a respective side surface of the diaphragm. The at least the pair of side walls define each of a generally open top and a generally hollow interior of the form. There is also means for securely attaching each end of the form or series of forms to one of a side surface of at least one of the pair of longitudinal members and an end of another form for forming the diaphragm from the concrete material. Bracing of upper edges is also provided.
