Buck panel for forming a buck assembly

A buck panel adapted to be interconnected with other panels to form a buck to frame a bulkhead or an opening in a wall for receiving a window or door, the buck panel comprising:

• a foam portion having an internal surface, an exterior surface, a first end, a second end opposite the first end, a first side, a second side opposite the first side, and a center portion positioned between the first side and the second side, at least a portion of the internal surface extending outward a predetermined distance to form a plurality of rebar holding members positioned along the center portion;
• and
• a support beam positioned longitudinally within the foam portion, the support beam having a first edge, a second edge, a plurality of plates extending between and connected to the first edge and the second edge, and a plurality of wings extending from the first edge and the second edge perpendicular to the internal surface of the foam portion in such a way that a portion of the wings protrude from the internal surface of the foam portion so as to be received in concrete poured over the internal surface,
• wherein the plurality of rebar holding members are provided with a first seat and a second seat defined by predetermined spaces between a first restraining finger, a second restraining finger, and a third restraining finger, and
• wherein the predetermined spaces between the first restraining finger, the second restraining finger, and the third restraining finger are sized such that compressibility and resiliency of the foam portion allows the first restraining finger, the second restraining finger, and the third restraining finger to frictionally grip rebar positioned in the first seat and the second seat.
