摘要

A disturbance-proof device connected between two vertically spaced beams for absorbing shocks upon a disturbance, includes a flat top plate, a flat bottom plate, and a plurality of flat supporting plate connected in parallel between the flat top plate and the flat bottom plate, each flat supporting plate having a substantially V-shaped profile with its width gradually reducing from the flat top plate toward the flat bottom plate, a flat top flange welded to the flat top plate, and a round rod at its bottom side inserted in between two parallel locating blocks raised from the bottom plate.
