WIND RESISTANT DEVICE
To provide a wind resistant device which has excellent wind resistant performance without applying a wind resistance pin or an electronic lock device in which shear fracture occurs at an earthquake.SOLUTION: A wind resistant device 100 is disposed together with a base isolation device 400 in a base isolation layer 510 of a base-isolated building 500, and the device at least includes: a steel first plate 10 and a steel second plate 20; a first friction material 40 disposed on one first wide width surface 11 of the first plate 10; a second friction material 50 disposed on one second wide width surface 21 of the second plate 20; and a fastening bolt 70 for pressure-contacting the first friction material 40 and the second friction material 50 contacting with each other. By a design tensile force N being introduced to the fastening bolt 70, the first friction material 40 and the second friction material 50 are pressure-contacted by having a design frictional force F, and when the first friction material 40 and the second friction material 50 are pulled with an external force Q equal to or greater than the design frictional force F and the contact between them is released, the design tensile force N is released.SELECTED DRAWING: Figure 4
【課題】地震時にせん断破壊される耐風ピンや電子ロック装置を適用することなく、優れた耐風性能を有する耐風装置を提供すること。【解決手段】免震建物５００の免震層５１０において、免震装置４００とともに配設される耐風装置１００であり、鋼製の第一プレート１０及び第二プレート２０と、第一プレート１０の一方の第一広幅面１１に配設されている第一摩擦材４０と、第二プレート２０の一方の第二広幅面２１に配設されている第二摩擦材５０と、相互に当接する第一摩擦材４０と第二摩擦材５０を圧接する締め付けボルト７０とを少なくとも有し、締め付けボルト７０に対して設計張力Ｎが導入されることにより、第一摩擦材４０と第二摩擦材５０が設計摩擦力Ｆを有して圧接されており、設計摩擦力Ｆ以上の外力Ｑで第一摩擦材４０と第二摩擦材５０が引っ張られて双方の当接が解除された際に、設計張力Ｎが解放される。【選択図】図４
