EARTHQUAKE REINFORCEMENT/SEISMIC ISOLATION STRUCTURE CONSTRUCTION METHOD FOR TRADITIONAL WOODEN BUILDING
To provide an "earthquake reinforcement/seismic isolation structure construction method" for a traditional wooden building located on soft ground and with a stone foundation structure for column bases.SOLUTION: When replacing a building's soft ground with a pressure-resistant foundation that has structural strength, a foundation stone of a stone foundation structure are directly supported. A back side of a replaced pressure platen foundation is smooth, and it is expected that it will slide on soft ground in the event of a large-scale earthquake. As a countermeasure, the back side of the pressure platen foundation has a foundation waffle beam shape structure. Furthermore, support steel pipe piles are press-fitted into the ground from the pressure platen foundation to a support stratum directly below. Uneven settlement of the pressure platen foundation is prevented. A foundation complex is formed by the foundation waffle beam shape and foundation piles, a pile head securing tube is attached to the steel pipe pile, it functions as a seismic isolation device, and can be used in the event of a large-scale earthquake. The structural strength of a traditional wooden building, which has a friction effect due to the viscous characteristics of the soft ground layer in the foundation complex, is also ensured.SELECTED DRAWING: Figure 1
【課題】立地：軟弱地盤、柱脚部基礎構造：石場建てである、伝統的構法木造建築物の「耐震補強・免震構造：工法」を提供する。【解決手段】軟弱地盤である建物地盤面を、構造耐力を有する耐圧盤基礎に置換施工する際に、石場建て構造の礎石を直接支持する。置換られた耐圧盤基礎の裏側は平滑で大規模地震の際に軟弱地盤上の滑走が想定され、対応策として、耐圧盤基礎の裏面を基礎ワッフル梁形状構造とし、更に上記耐圧盤基礎より直下の支持地層まで、支持鋼管杭を地中圧入施工し、耐圧盤基礎の不動沈下を阻止し、基礎ワッフル梁形状＋基礎杭＝基礎複合体、を形成し、鋼管杭に杭頭部確保筒を装着し、免震装置としての機能を具備し、大規模地震発生に対応し、基礎複合体に軟弱地盤地層の粘性特性が係るフリクション効果を有する伝統木造建築物の構造耐力を併せて確保する。【選択図】図１
