REPLACEMENT STEEL PLATE DECK OF CONCRETE SLAB AND REPLACEMENT METHOD OF CONCRETE SLAB
PROBLEM TO BE SOLVED: To provide an environment-friendly replacement steel plate deck of concrete slab superior in productivity and workability, and a replacement method of the concrete slab.SOLUTION: A steel plate deck, which is placed on flanges of a main girder of a bridge from which existing concrete slabs are disassembled and removed, includes, on the lower plane thereof, a steel material with projection on the plane which comes into contact with injection concrete for forming a square space for integrating the main girder with the injection concrete.SELECTED DRAWING: Figure 4
【課題】製作性および施工性が良好でかつ環境に優しい、コンクリート床版の張替え用鋼床版およびコンクリート床版の張替え工法を提供する。【解決手段】既設のコンクリート床版を解体除去した橋梁の主桁のフランジ上に張替えられる鋼床版であって、注入コンクリートにより前記主桁と一体化するための四角形空間を形成し得る、注入コンクリートに接する面に突起が付いた突起付き鋼材を下面に備えていることを特徴とするコンクリート床版の張替え用鋼床版。【選択図】図４
