Abstract
Abstract A construction trellis unit for the formation and setting up of beams and the like in cement conglomerate, consists of a twosided reticular framework movable longitudinally or transversely to its axis by bearing rollers. A metal form with movable walls can be slid into the framework for effecting the castings of conglomerate. When completed, the castings are lowered directly upon bridge bearings by hoists movable upon the upper booms of the trellis and prior to the withdrawal of the movable form.
