To provide a wind lock mechanism capable of appropriately controlling movements of a lower structure and an upper structure under a wind load and presenting seismic isolation effects more surely and effectively than the prior arts by cancelling a movement controlled state in the case of earthquake.SOLUTION: The present invention relates to a wind lock mechanism A which is provided in a seismic isolation layer 3 between an upper structure 1 and a lower structure 2 in parallel with a seismic isolation device. The wind lock mechanism is configured by comprising a wind lock mechanism main body part 4 and an elastic spring part 5 which are disposed in series between the upper structure 1 and the lower structure 2. The wind lock mechanism also comprises: a shaft spring device 6 including a spring 6a which is elongated/contracted in a vertical direction; a shaft material 7 of which the axial direction is disposed in the vertical direction and which is disposed while connecting the lower end side to the lower structure 2 via the shaft spring device 6 and being energized upwards by the shaft spring device 6; and a bundle material 9 of which the lower end is pin-coupled 8 to an upper end of the shaft material 7 and which is disposed while pressing its upper end to the upper structure 1 via the elastic spring part 5 by causing an energizing force of the spring 6a that is brought into a compressed state, of the shaft spring device 6 to act thereon via the shaft material 7.SELECTED DRAWING: Figure 1
【課題】風荷重時には下部構造と上部構造とを移動を好適に制御し、地震時には移動制御状態を解除して免震効果を、従来より確実且つ効果的に発揮させることを可能にする風ロック機構を提供する。【解決手段】上部構造１と下部構造２の間の免震層３に免震装置と並列に設けられる風ロック機構Ａであって、上部構造１と下部構造２の間に直列配置される風ロック機構本体部４と弾性バネ部５を備えて構成されるとともに、上下方向に伸縮するバネ６ａを有する軸バネ装置６と、軸線方向を上下方向に配し、下端部側を軸バネ装置６を介して下部構造２に接続しつつ軸バネ装置６によって上方に付勢して配設される軸材７と、下端部が軸材７の上端部にピン結合８され、軸バネ装置６の圧縮状態とされたバネ６ａの付勢力が軸材７を通じて作用することで上端部を弾性バネ部５を介して上部構造１に押圧して配設される束材９とを備えて構成する。【選択図】図１
