Connector assembly for allowing relative movement between two building members

A building connector assembly comprising:

• a first building member comprising a concrete slab;
• a second building member;
• a track comprising one or more protrusions affixed to a surface of the track, each of the one or more protrusions being offset from a center of the surface towards one edge of the surface, the one or more protrusions embedded into to the concrete slab such that the track is secured against a slab edge of the concrete slab;
• and
• a connecting member connected to the second building member;
• wherein the connecting member is movably coupled to the track and movable along the track;
• wherein the connecting member includes opposed end portions, a base, and an extension that extends outwardly from the track for connecting to the second building member;
• wherein the track includes opposed channels that extend from the surface of the track in a first direction, and wherein the base of the connecting member is retained in the opposed channels and is permitted to slide back and forth therein;
• wherein the one or more protrusions extend from the surface of the track in a second direction opposing the first direction;
• and
• wherein the building connector assembly permits relative movement between the first and second building members by permitting the connecting member to slide along the track.
