SUPPORT STRUCTURE OF SUPERSTRUCTURE
To suppress excessive lifting and damage of a superstructure, and to mitigate the impact when the lifted superstructure descends.SOLUTION: In a support structure 10D of a superstructure that supports a superstructure 12 via a pile 18 having a space 24 opened upward in a pile head 2202, a resistance mechanism 20D that creates resistance while allowing lifting with respect to the lifting of the superstructure 12, and creates resistance while allowing the descent with respect to the descent of the superstructure 12 when the superstructure 12 descends after lifting is provided over the superstructure 12 and the space 24. The resistance mechanism 20D comprises a rod 40 having an upper small diameter portion 4004 projecting downward from a lower surface 1402 of the superstructure 12 and a large diameter portion 4006 having a cross-sectional area larger than that of the upper small diameter portion 4004 and inserted into the space 24, and an elastic member 42 through which the upper small diameter portion 4004 is penetrated and the outer peripheral portion thereof is attached to an inner peripheral surface 1802 of the pile 18.SELECTED DRAWING: Figure 1
【課題】上部構造物の過大な浮き上がりや損傷を抑制し、かつ浮き上がった上部構造物が降下する際の衝撃を緩和する。【解決手段】杭頭２２０２に上方に開放された空間部２４を有する杭１８を介して上部構造物１２を支持する上部構造物の支持構造１０Ｄであって、上部構造物１２と空間部２４とにわたり、上部構造物１２の浮き上がりに対して浮き上がりを許容しつつ抵抗を生じ、かつ、上部構造物１２の浮き上がり後の降下時に降下に対して降下を許容しつつ抵抗を生じる抵抗機構２０Ｄが設けられている。抵抗機構２０Ｄは、上部構造物１２の下面１４０２から下方に突設される上部小径部４００４と、上部小径部４００４よりも断面積の大きい大径部４００６とを有し空間部２４に挿入されるロッド４０と、上部小径部４００４が貫通されて杭１８の内周面１８０２にその外周部が取着された弾性部材４２とを含んで構成されている。【選択図】図１
