制震壁における粘性流体の零れ防止構造

Japanese Patent JP7381371

B2

To provide a viscous fluid spill prevention structure in a seismic control wall capable of transporting the seismic control wall having a predetermined length dimension in the vertical direction, while suppressing transportation costs and preventing the viscous fluid from spilling.SOLUTION: Provided is a structure to prevent a viscous fluid from spilling in a seismic control wall 1 provided with an outer wall body 2 filled with a viscous fluid 4 and an inner wall body 3 inserted from above, which is provided with a liquid pool portion 21 having an opening 24 at the upper end of the outer wall body 2 opening upward. And at the upper portion of the liquid pool portion 21, a spill preventer 25 is provided which is formed to cover the opening 24 to prevent the viscous fluid 4 from spilling out of the opening 24 when the seismic control wall 1 is mounted on the truck bed in an inclined position and transported, by extending over the entire left-right direction of the liquid pool portion 21 and projecting toward the inner wall body 3.SELECTED DRAWING: Figure 4
