JOINT STRUCTURE BETWEEN SEISMIC ISOLATOR AND STEEL COLUMN
PROBLEM TO BE SOLVED: To provide a joint structure between a seismic isolator and a steel column, facilitating control of installation accuracy of the steel column while securely transmitting tensile or compression force between the seismic isolator and the steel column.SOLUTION: A joint structure between a seismic isolator 10 and a steel column 40 comprises: an upper base plate 30 connected to an upper surface of an upper flange 13 of the seismic isolator 10; a shrinkage-compensating mortar layer 35 positioned on the upper surface of the upper base plate 30; and a column base plate 41 for a steel column 40 arranged on the shrinkage-compensating mortar layer 35. A female threaded portion 37 is formed in the upper base plate 30, and a through hole 43 is formed in the column base plate 41 for the steel column 40, wherein a connecting bolt 44 is screwed into the female threaded portion 37 in the upper base plate 30 and the connecting bolt 44 is inserted into the through hole 43 in the column base plate 41 for the steel column 40, being engaged using a nut 45.SELECTED DRAWING: Figure 2
【課題】免震装置と鉄骨柱との間で引張力および圧縮力を確実に伝達しつつ、鉄骨柱の建て込み精度を容易に管理できる、免震装置と鉄骨柱との接合構造を提供すること。【解決手段】免震装置１０と鉄骨柱４０との接合構造は、免震装置１０の上フランジ１３の上面に接合された上部ベースプレート３０と、上部ベースプレート３０の上面に設けられた無収縮モルタル層３５と、無収縮モルタル層３５上に配置された鉄骨柱４０の柱脚ベースプレート４１と、を備える。上部ベースプレート３０には、雌ねじ部３７が形成され、鉄骨柱４０の柱脚ベースプレート４１には、貫通孔４３が形成され、上部ベースプレート３０の雌ねじ部３７には、連結ボルト４４が螺合され、連結ボルト４４は、鉄骨柱４０の柱脚ベースプレート４１の貫通孔４３に挿通されて、ナット４５が締結されている。【選択図】図２
