WIDENING BRACKET STRUCTURE AND FLOOR SLAB WIDENING STRUCTURE
To enable widening of an existing bridge without adding main girders and bridge piers.SOLUTION: A widening bracket structure comprises: an existing steel bracket 12 attached to an existing steel main girder 102 so that an existing cantilever floor slab 110, which is provided to extend outward in a bridge width direction from the existing steel main girder 102 of an existing bridge 100, can be supported from below; and a new widening steel bracket 14 having a connection member 16 for supporting the existing steel bracket 12 from below, and a widening bracket member 18 connected to the connection member 16 and extending outward in the bridge width direction from the existing steel bracket 12. The connection member 16 of the new widening steel bracket 14 is attached to the existing steel main girder 102 and the existing steel bracket 12 of the existing bridge 100.SELECTED DRAWING: Figure 2
【課題】主桁および橋脚の増設をせずに既存橋梁の拡幅を可能にする。【解決手段】既設橋梁１００の既設鋼製主桁１０２よりも橋幅方向外側に張り出して設けられた既設片持ち床版１１０を下方から支持可能なように、既設鋼製主桁１０２に取り付けられた既設鋼製ブラケット１２と、既設鋼製ブラケット１２を下方から支持する仕口部材１６、および仕口部材１６に連結されていて既設鋼製ブラケット１２よりも橋幅方向外側に延びる拡幅ブラケット部材１８を有する新設拡幅鋼製ブラケット１４と、を備える拡幅ブラケット構造体であって、新設拡幅鋼製ブラケット１４の仕口部材１６は、既設橋梁１００の既設鋼製主桁１０２および既設鋼製ブラケット１２に取り付けられている。【選択図】図２
