Abstract
The chairs include a lower chair portion for supporting multiple prestressing cables at the bottom of a plank and a narrow upper chair portion for supporting an upper prestressing cable located in the web between the hollow cores of the prestressed plank. The upper chair portion can be inserted into the strand receiving cups of the lower portion to form a structurally sound support for accurately placing the top and bottom reinforcing strands in the plank as it is cast.
