SUPERSTRUCTURE BEARING STRUCTURE
To provide a superstructure bearing structure which is unlikely to affect the displacement of a superstructure due to thermal expansion, makes it possible to prevent crashing into a travel quantity restriction member and the occurrence of large collision noise, and furthermore to firmly connect the superstructure to the lower structure in an abrupt displacement of the lower structure with respect to the superstructure.SOLUTION: A superstructure bearing structure 1 is equipped with a lamination rubber bearing 8 which is connected at an end 2 to an end part 3 of a bridge girder 6 while at the other end 5 connected to a bridge pier 6 and bears the end part 3 with respect to the bridge pier 6; a travel restriction member 9 which restricts the relative movement of the lamination rubber bearing 8 at the end 2 in a direction X travel exceeding a certain amount with respect to the bridge pier 6; and an attenuation device 10 provided in the restriction member 9.SELECTED DRAWING: Figure 1
【課題】熱伸縮に基づく上部構造物の変位に悪影響を与える虞がなく、移動量制限部材への激突及び大きな衝突音の発生を回避でき、しかも、上部構造物に対しての下部構造物の急速な変位では、上部構造物を下部構造物に剛に連結することができる上部構造物支承構造を提供すること。【解決手段】上部構造物支承構造１は、一端２で橋桁の一端部３に連結されている一方、他端５で橋脚６に連結されていると共に橋脚６に対して一端部３を支持する積層ゴム支承８と、積層ゴム支承８の一端２の方向Ｘの一定量を超える橋脚６に対する相対的な移動を規制すると共に方向Ｙの一定量以下の橋脚６に対する移動を許容する移動量制限部材９と、移動量制限部材９に設けられた減衰装置１０とを具備している。【選択図】図１
