Claim:
A tie-rod assembly arranged to be positioned in a concrete forming structure so as to extend through a concrete forming region and through two wall forming sections that define the concrete forming region, said tie-rod assembly comprising: a) an elongate cylindrically shaped tie-rod having exterior threads along at least a portion of an outer cylindrical surface of the tie-rod; b) a sleeve section comprising: i) a tapered sleeve member defining a through passageway to receive the tie-rod, said tapered sleeve member having a smaller diameter circumferential forward end sized to fit closely to the exterior surface of the tie-rod, and having a larger diameter rear end spaced radially outwardly from the tie-rod, ii) a positioning member connected to the larger diameter portion of the tapered sleeve member, and having a threaded opening to receive the tie-rod and to threadedly engage the exterior threads of the tie-rod, iii) a locking member in positive engagement with the tapered sleeve member and fixedly positioning said tapered sleeve member to the elongate cylindrically shaped tie-rod, c) said tie-rod and said sleeve section being arranged so that with the sleeve section positioned with the tie-rod extending therethrough, the sleeve section can be rotated, and with the threaded positioning member engaging the threads of the tie-rod, move the sleeve-section to a desired location along the tie-rod; and d) said tapered sleeve member being configured to extend through the concrete forming region and having a connection to the tie-rod that is also adapted to be positioned through the concrete forming region through the through passageway of the tapered sleeve member where after the concrete wall is formed, the tie-rod assembly is adapted to be removed by impacting the front end of the tie-rod and causing the tie-rod assembly to be moved out of the concrete wall formed in the forming region.
