BRIDGE SUPPORTER WITH IMPROVED MAINTENANCE

摘要

Disclosed is a bridge supporter, comprising: an upper plate; a lower plate spaced from the upper plate in the vertical direction; an elastic pad disposed between the upper plate and the lower plate; an upper wedge fixed on a lower surface of the upper plate; a lower wedge fixed on an upper surface of the lower plate; an intermediate wedge mounted on the lower wedge, facing a side surface of the upper wedge, and being broken in response to a horizontal force of at least a predetermined level; and a shear pin inserted into the lower wedge and the intermediate wedge and fixing the intermediate wedge and the lower wedge. The intermediate wedge can be sheared and fixed without welding or bolt-engagement so that the intermediate wedge can be easily replaced when the same is broken.;COPYRIGHT KIPO 2019
