About this detail

This floor expansion joint detail connects across an existing concrete floor slab and structural steel framing assembly at Level 03.1. The joint system utilizes continuous extruded aluminum base frames anchored to the existing floor slab with one-quarter inch by one-and-three-quarter inch tappers spaced at eighteen inches on center, along with injection molded turnbars at eighteen inches on center. A continuous extruded aluminum center pan fits between the base frames, backed by continuous sealant and backer rod on both sides and factory-attached number twelve by three-quarter inch tek screws. A stainless steel foil heat shield and RFX-4F insulation drape suspend below the joint assembly. The adjacent floor finishes incorporate non-shrink grout, carpet and carpet pad as required, and a concrete infill.
