FOAM LINER FOR CASTING OBJECTS IN POURED WALLS

摘要

A liner holds objects in place within a form for a poured wall. The liner includes a backing sheet and a plurality of foam bed joints arranged in a substantially parallel fashion along a length dimension. A plurality of separate foam head joints are attached along a height dimension, wherein opposing ends of the foam head joints engage adjacent bed joints to define a plurality of regions on the backing sheet for receiving the objects to be cast in the poured wall. Each foam joint has a rounded cross section to form a curved grout line between the objects cast in the poured wall. The foam joints include an outer protective skin to prevent the poured wall material from bonding with the foam cells. A method of forming the liner includes aligning the separate foam bed joints and head joints in a grid and then pressing an adhesive-backed paper sheet against the foam joints.
