Abstract
A tie-bar assembly including a tie-bar pocket, a first tie-bar attachable to the tie-bar pocket, and a second tie-bar attachable to the tie-bar pocket in a manner such that the second tie-bar is coupled to the first tie-bar. During construction, the first tie-bar is attached to the tie-bar pocket. This assembly is fastened to the form. After the first slab is poured the first tie-bar and the tie-bar pocket are embedded in the first slab. The form is removed, and the interior of the tie-bar pocket and a bent portion of the first tie-bar are exposed. The bent portion of the second tie-bar is then inserted into the tie-bar pocket and engages with the first tie-bar. The second slab is then poured and encapsulates the second tie-bar.
