<p>Disclosed is an attachment structure for a layered rubber body. Said attachment structure minimizes the installation height of the layered rubber body, prevents vertical tensile forces from acting on the layered rubber body, and makes it possible to replace the layered rubber body using a low amount of jack-up. The provided structure attaches a layered rubber body (8) to a top structure (2) and a bottom structure (3). Said layered rubber body is formed by joining a flange plate (6) to a layered rubber section (4), said flange plate having an extension section (6a) that extends further outwards than the outer edge of the layered rubber section (4). The disclosed attachment structure (1) is provided with: an upper anchor plate (10A) affixed to the bottom surface of the top structure (2); a lower anchor plate (10B) affixed to the top surface of the bottom structure (3); and shear keys (12) that engage with the upper anchor plate (10A) or the lower anchor plate (10B) so as to transmit, to the extension section (6a) of the flange plate (6) in the layered rubber body (8), horizontal forces resulting from horizontal relative displacement but not vertical forces resulting from vertical relative displacement.</p> |
