Wooden foundation base seismic isolation system

摘要

An object of the present invention is allowed to reduce the vibration part of the foundation base by the rapid vibration of the earthquake, and up and down shaking, the provision of wooden foundation foundation seismic isolation structure that can be associated with both of the roll. A top and bottom of the swing by holding the foundation in foundation top hardware 4 incorporates a device for relief to earthquake in the seismic isolation foundation rubber 8 withstand the rapid vibration in the anchor auxiliary rubber 6 in the base, left and right of the swing, The up and down in the corner spring 14 is reduced by seismic isolation concrete rubber 10 by suppressing the front and back of the swing, left and right, MenShinyokofu rubber soften the sway in the corresponding seismic isolation base rubber 17 to the impact of large earthquakes in the intensity of the front and back, joint 19 soften the impact of concrete cloth foundation of the left and right, up and down vibration isolation vibration rubber joint 20 is also made to the spring water stop plate of Matamizu withstand the shock of the corner spring and concrete cloth foundation. .BACKGROUND
