Anchor sheet positioning and connection system

摘要

Attachment devices are described for attaching and locating overlapped anchor sheets while allowing for some relative movement as to expansion and contraction. Generally, the devices are a male/female connection on corresponding sheets and expansion openings or apertures surrounding either the male or female part to provide for areas of flexibility to provide for possible movement of either the male or female part.
