ABSTRACT:
An interlock grate structure is provided which includes longitudinal load bearing span bars having lateral locating holes spaced therealong for receiving transverse tie bars, the transverse tie bars having axial locking means which engage the longitudinal span bars at the point of juncture to prevent axial displacement of the tie bar relative to the span bar. A longitudinal lock rod serves to interlock the position of the transverse tie bar locking means with respect to the longitudinal span bar.
