Structural tie-down apparatus

摘要

An arrangement for anchoring a roof of a building so that it can resist wind forces captures each roof truss, or other roof framing member, under a wire rope passed through a sequence of eyebolts protruding above a top plate of one of the walls of. Each of the eyes is the upper portion of one of a plurality of rod assemblies, each of which is connected to a respective one of a plurality of anchors disposed beneath the wall. A turnbuckle connecting each rod assembly to a respective eyebolt is used to draw the eyebolt down against the top plate and hence apply tension to the wire rope. A connecting nut at the bottom of each rod assembly attaches the rod assembly to a threaded upper end of an anchor set in the foundation of the building. Thus, tightening the turnbuckles firmly ties down the roof to the foundation.
