PROBLEM TO BE SOLVED: To provide a forced double-surface slide supporting device for structure having a simple structure, capable of substantially attenuating a horizontal displacement in one direction acted at the time of occurrence of earthquake and reducing a reaction force when a sliding operation is started.SOLUTION: There are provided a lower shoe 6 fixed to a lower part structure 2 and having an upper surface constituting a lower part slide surface 13; an upper shoe 8 fixed to an upper part structure 3 and having a lower surface constituting an upper part slide surface 14; and an elastomeric bearing 9 including an upper connecting steel plate 11 formed with an upper part displacement transmittance opening constituting the upper part slide surface together with the upper shoe and a lower connecting steel plate 12 formed with a lower part displacement transmittance opening constituting the lower part slide surface together with the lower shoe. The lower part displacement transmittance member in the upper part displacement opening transmits a displacement in one direction, the upper part displacement transmittance member in the lower part displacement transmittance opening transmits a displacement in one direction crossing at a right angle, a forced double-surface sliding is performed in one direction crossing at a right angle through upper and lower sliding surfaces, and a sliding in the other direction crossing at a right angle is prohibited.SELECTED DRAWING: Figure 1 |
