Crown post
A crown post is a term in traditional timber framing for a post in roof framing which stands on a ''tie beam'' or ''collar beam'' and supports a ''collar plate''.〔Alcock, N. W.. Recording timber-framed buildings: an illustrated glossary. London: Council for British Archaeology, 1989. G5〕 Historically, crown posts were called king posts, but this usage is confusing and obsolete. A crown post is designed to be in a compression and transfers weight to the tie beam, where a king post is designed to be in tension and supports the tie beam. In the U.K a ''crown strut'' is similar to a crown post but does not carry a plate. ==References==
