ABSTRACT:
The invention is a molded plastic void hold down device utilized in concrete beams to restrict and hold down the vertical and lateral movement of voids placed within the concrete beam during construction. In particular, the hold down device comprises a molded plastic structure that includes a lower flange that extends over a top portion of the void, a coupling sleeve integrally formed with the lower flange and extending upwardly therefrom for frictionally coupling to the lower end portion of a down rod, and a web integrally formed with both the coupling sleeve and the lower flange and extending outwardly from opposite sides of the coupling sleeve.
