How do tie rods attach to a structure?

Tie rods are attached by sliding a gusset plate or knife plate, which is fastened to a structure, in between the ears of a clevis. A clevis pin or A325 structural bolt, is then assembled through the pin holes on the clevis and through the hole in the plate. Gusset plates are attached to the structure by through bolts or lag screws. The gusset plates are designed by an engineer with the proper quantity and size of bolts necessary to secure the gusset plate to the structure and develop the full strength of the assembly.

A clevis is threaded onto either end of an externally threaded rod to form a tie rod assembly. These parts function as a tension rod because at one end, a clevis threads onto left hand threads and on the other end a clevis threads onto right hand threads. These opposite threaded ends allow the tie rod to be tightened or loosened by turning the rod in the middle.
