BRIDGE HAVING DECK SLAB CONCRETE STRUCTURE ON PLURAL BEAMS, CONSTRUCTING METHOD THEREOF AND PRECAST PARTIAL-DEPTH DECK SLAB CONCRETE STRUCTURE USED IN CONSTRUCTING SAME

摘要

The present invention relates to a precast subplate for bridge fabrication, a bridge fabricated using the same, and a construction method thereof, wherein the first bridge support beam and the second bridge are arranged in the axial direction on at least one of a bridge and a bridge. A plurality of bridge support beams including support beams and concrete precast subplates used for fabricating the bottom plate of a bridge formed above the bridge support beams, the first bridge support beams and the second bridge support beams. A first segmented concrete partial floor plate formed in a plate shape having a thickness smaller than the bottom plate so that both ends are supported and mounted on an upper side of the first fragment concrete floor plate; A second segmented concrete subfloor which is supported and mounted on an upper side of the first bridge supporting beam and is spaced apart in the axially perpendicular direction of the first segmented concrete partial deck and is formed in a plate shape having a thickness smaller than that of the bottom plate. and; Reinforcing the first segment concrete subplate and the second segment concrete subplate, and an upper interspace of the first bridge support beam between the first segment concrete subplate and the second segment concrete subplate A connecting reinforcing bar formed across the bridge to be integrated with the bridge supporting beam; It is configured to include a concrete connecting portion connecting the first segment concrete subplate and the second segment concrete subplate, the shape and position of the segmental subplate mounted on a plurality of bridge support beam of the bridge is maintained as it is As the concrete connection is formed as firmly as possible, the segmental bottom plate is firmly installed and fixed by the adjacent segmental bottom plate without using a swivel in the side edge corner area (cantilever section) of the bridge. It is not necessary to install the copper bars between the supporting beams for the construction, and because the precast partial floor plate itself acts as the formwork when placing the concrete slabs, it is unnecessary to manufacture and install the formwork. However, the compressive stress is reduced by tensioning the tension member in the axial direction. It is easy to introduce into the track in advance, and by using a single precast subplate, a subplate having a thickness smaller than the thickness of the sole to be completed is mounted on the bridge support beam more quickly, thereby simplifying the construction of the soleplate. The present invention provides a precast subplate for bridge fabrication, a bridge fabricated using the same, and a method of fabricating the same.;Partial deck, segmented floorboard, crossbeam, concrete protrusion, tension member
