Attic granary interior tie rod detail on north gable (east segment)

Iron tie rods were added in the 20th century as restraints against roof thrust acting on the eaves wall plates. The rod is seen entering the wall plate just below the upper right corner of the photo (the bricks are non-original in-fill). A nut secured the threaded end of the rod against the exterior vertical face of the plate. These interior rods apparently replaced exterior rods [see DTHPH7--1001.01.029] which undoubtedly became ineffective because of the rotting-out of the exposed end-grain of the wall plate securing the rod spanning the north gable at the eaves level.
