摘要： A bridge deck panel support system and method for supporting precast bridge deck panels on a bridge girder. The bridge deck panel support system (10) comprises at least one grade bar support member (24) which is anchored to the bridge girder (14) with a grade bar support anchor (16) so as to extend upwardly from the bridge girder (14). At least one grade bar (28) for supporting one or more deck panels (12) is secured to the upper portion (26) of the grade bar support member (24), the grade bar (28) being selectively spaced from the girder (14) such that a grout receiving space (32) is defined between the grade bar (28) and the girder (14). The grout receiving space (32) is filed with non-shrink grout (34) such that the load of the deck panels (12) is transferred from the grade bar (28) to the grout (34). The method of the present invention includes the steps of securing the grade bar support member (24) to the girder (14), securing the grade bar (28) to the grade bar support member (24), and substantially filling the grout receiving space (32) with non-shrink grout (34).

摘要： A method of replacing an existing roadway on structure in which at least one of the lanes of the roadway is cut into rectilinear sections during a first nonpeak traffic period. The sections are left in place, and temporary traffic bearing members are positioned over the cuts to permit the flow of traffic over all of the lanes of the roadway during an ensuing peak traffic period. Orthotropic roadway modules are preformed and paved at a factory or other remote location, and each of these modules has a width equal to that of the one lane. During a second nonpeak traffic period one or more of the modules is transported to the site, the traffic bearing members and the rectilinear sections are removed and the module is connected in place. The foregoing steps are repeated during successive traffic periods until the entire roadway has been replaced.

摘要： Each one of a plurality of parallel horizontal beams has longitudinally spaced vertical slots extending transversely through it, with the lower wall of each slot formed by the top of the free end portion of a tongue struck out of the beam. Resting on these tongues are parallel cross bars that extend through the slots and have notches extending downwardly from the tops of the bars receiving the portions of the beams above the slots, with those portions substantially engaging the bottoms of the notches. The height of the tongues is great enough to permit the bars during assembly to be inserted in the slots while the tongues are bent laterally out of the beams, whereupon the bars can be raised in the slots and the tongues bent back beneath the bars to support them.

摘要： Disclosed are a composite deck structure for a bridge, and a bridge structure and a construction method thereof. The composite deck structure includes a top plate (1), longitudinal ribs (2), and transverse ribs (3), where the longitudinal ribs (2) are fixedly connected to the transverse ribs (3), and are connected to the diaphragms (4) by means of the transverse ribs (3), and the transverse ribs (3) are not provided with cutouts for accommodating the longitudinal ribs (2). According to the composite deck structure, no cutout is provided on the diaphragms (4), and stress generated by the cutouts is reduced; hot-rolled section steel is used for longitudinal ribs (2) and transverse ribs (3) instead of welded steel plates, such that welding seams are reduced and fatigue resistance of the composite deck structure is improved.
