EXTENSION METHOD AND EXTENSION STRUCTURE
To provide an extension method and an extension structure that can realize rigid connection of a newly constructed structural material to an existing structure portion while avoiding a decrease in the strength of the existing structure portion when joining the newly constructed steel structural material to the existing structure portion made of concrete.SOLUTION: A newly constructed widening portion 10 made of concrete is constructed on an outer periphery of an existing structure portion 1, and a plurality of through bolts 25 are provided to pass through the newly constructed widening portion 10 along an extending direction of the through bolt that is perpendicular to an extending direction Y of a newly constructed structural material. A pair of joining plates 20 fixed to the newly constructed structural material 50 while facing each other along an extending direction of the through bolt are arranged so as to sandwich the newly constructed widening portion 10 along the extending direction of the through bolt, and are connected to the newly constructed widening portion 10 with the plurality of through bolts 25.SELECTED DRAWING: Figure 5
【課題】コンクリート造の既設構造部に対して鉄骨造の新設構造材を接合するにあたり、既設構造部の強度低下を回避しながら、既設構造部に対する新設構造材の剛接合を実現できる増築工法及び増築構造を提供する。【解決手段】既存構造部１の外周部にコンクリート造の新設拡幅部１０を構築すると共に、新設構造材延在方向Ｙに直交する貫通ボルト延在方向に沿って新設拡幅部１０を貫通する複数の貫通ボルト２５を設け、貫通ボルト延在方向に沿って対向配置された状態で新設構造材５０に固定された一対の接合プレート２０を、貫通ボルト延在方向に沿って新設拡幅部１０を挟み込む形態で配置して複数の貫通ボルト２５により新設拡幅部１０に接合する。【選択図】図５
