JUNCTION STRUCTURE OF SEISMIC ISOLATOR TO STEEL-PIPE COLUMN, AND BASE ISOLATED BUILDING
PROBLEM TO BE SOLVED: To provide a junction structure of a steel-pipe column and a seismic isolator where junction strength at the junction between the seismic isolator and the steel-pipe column has further increased and transmission performance of the vertical load can be improved.SOLUTION: A junction structure 1 between a seismic isolator and a steel-pipe column comprises a seismic isolator 10, a steel-pipe column 40 provided on the seismic isolator 10, and an upper foundation 50 formed around a periphery of column base part of the steel-pipe column 40. The seismic isolator 10 has an upper flange 13 on an upper end side. The steel-pipe column 40 comprises: a cylindrical steel-pipe 42 where a base plate 41 is provided at a lower end face and the column base part has enlarged in its diameter; and a concrete body 43 which is formed by filling concrete into an inside of the steel-pipe 42. The base plate 41 of the steel-pipe column 40 is jointed at the upper flange 13 of the seismic isolator 10 by using fixing bolts 132 and female screw parts 45.SELECTED DRAWING: Figure 2
【課題】免震装置と鋼管柱との接合部において、接合強度をより高めるとともに、鉛直荷重の伝達性能をより向上できる、鋼管柱と免震装置の接合構造を提供すること。【解決手段】免震装置と鋼管柱との接合構造１は、免震装置１０と、免震装置１０の上に設けられた鋼管柱４０と、鋼管柱４０の柱脚部の周囲に形成された上部基礎５０と、を備える。免震装置１０は、上端側に上フランジ１３を備える。鋼管柱４０は、下端面にベースプレート４１が設けられてかつ柱脚部が拡径された筒状の鋼管４２と、鋼管４２の内部にコンクリートが充填されて形成されたコンクリート体４３と、を備える。鋼管柱４０のベースプレート４１は、免震装置１０の上フランジ１３に固定ボルト１３２および雌ねじ部４５で接合される。【選択図】図２
