BRIDGE DECK SLAB SUPPORT STRUCTURE AND REPLACEMENT METHOD OF DECK SLAB
PROBLEM TO BE SOLVED: To provide a bridge deck slab support structure and a replacement method of deck slab capable of carrying out a work to replace a reinforced concrete deck slab laid on a bridge with a steel deck slab in a short time.SOLUTION: After attaching a deck slab support bracket 5 above a web 3b of a main girder 3, a concrete deck slab is removed excluding a part of an upper flange 3a as left part 4. A steel deck slab 2 which has a lateral rib 21, vertical rib 22 and a deck plate 20 is placed in the removed place on the deck slab support bracket 5 and joined with each other. Pavement construction is made on the upper face of the deck plate 20 to form a road surface 7.SELECTED DRAWING: Figure 1
【課題】橋梁に敷設されている鉄筋コンクリート床版を鋼床版に取り替える作業を極力短時間で行うことができる橋梁の床版支持構造と床版取替方法を提供する。【解決手段】主桁３のウェブ3bの上方に床版支持ブラケット５を取付けて、上フランジ3a上の部分を残留部４として残してコンクリート床版を除去する。この除去した部分に横リブ21と縦リブ22、デッキプレート20とを有する鋼床版２を床版支持ブラケット５に載置させて接合させる。デッキプレート20の上面に舗装施工して路面７を形成する。【選択図】図１
