Simply supported girder bridge floor continuous new construction and construction method
The invention relates to simply supported girder bridge floor continuous new construction. The construction comprises multiple girders of a simply supported girder bridge and bridge floor plates arranged on the girders, ultra-high performance concrete connecting plates are arranged and connected between the bridge floor plates on the adjacent girders, arc-shaped steel supporting pieces located at the same height are embedded in end faces of the adjacent girders, steel tube ultra-high performance concrete segments are arranged between the arc-shaped steel supporting pieces, two ends of each steel tube ultra-high performance concrete segment are connected with end faces of the girder at corresponding side respectively, and the invention further relates to two construction methods applied to new-built simply supported girder bridge and existing simply supported girder bridge. By utilizing the ultra-high performance concrete connecting plates arranged in the simply supported girder bridge floor continuous new construction, tensile deformation in longitudinal direction of a bridge at continuous construction on bridge floor caused by girder deformation of the adjacent girders is achieved, and corrosion resistant performance is improved; and by utilizing compression resistance performances of the ultra-high performance concrete connecting plates and the steel tube ultra-high performance concrete segments, compression deformation in longitudinal direction of the bridge at the continuous construction on the bridge floor caused by the girder deformation of the adjacent girders is achieved.
