Construction method of simply supported girder bridge continuous slab-deck structure with prestress and structure of construction method
The invention relates to a construction method of a simply supported girder bridge continuous slab-deck structure with prestress. The prestress of a concrete connecting plate is exerted by making two prestress ribs of each set gather to the central lines of the prestress ribs through iron block sets, and therefore the longitudinal tensile deformation of adjacent main girder beam body deformation at the continuous slab-deck structure is resisted under the effects of temperature drop loads, concrete shrinkage and creep and the like. The construction method is free of prestress tensile machines, can be widely applied to the field of bridge construction, and includes the steps of newly establishing a continuous slab-deck simply supported girder bridge and refitting a continuous slab-deck of an existing simply supported girder bridge.
