Anchor plate

An anchor plate, floor plate or wall washer is a large plate or <a href="/facts/Washer_(hardware)/3ThpTMAA">washer</a> connected to a <a href="/facts/Tie_rod/NXCdXAnC">tie rod</a> or <a href="/facts/Screw/Rr0k38TC">bolt</a>. Anchor plates are used on exterior walls of <a href="/facts/Masonry/TlaDzpUp">masonry</a> buildings, for structural reinforcement against lateral bowing. Anchor plates are made of <a href="/facts/Cast_iron/lASt55k2">cast iron</a>, sometimes <a href="/facts/Wrought_iron/zynpjrIv">wrought iron</a> or <a href="/facts/Steel/aN6qWo4H">steel</a>, and are often made in a decorative style.
They are commonly found in many older cities, towns and villages in <a href="/facts/Europe/DTAtrKfh">Europe</a> and in more recent cities with substantial 18th- and 19th-century brick construction, such as <a href="/facts/New_York_City/YlyvFmVC">New York</a>, <a href="/facts/Philadelphia/2bFFCCTU">Philadelphia</a>, <a href="/facts/St._Louis%2c_Missouri/22beLecX">St. Louis</a>, <a href="/facts/Cincinnati/PcyTWhS4">Cincinnati</a>, and <a href="/facts/Charleston%2c_South_Carolina/dB8lmPF2">Charleston, South Carolina</a>; and in older <a href="/facts/Earthquake/NGjIzagw">earthquake</a>-prone cities such as <a href="/facts/San_Francisco/cb9l7hbC">San Francisco</a>, as well as across all of Europe. 
One popular style is the star anchor, an anchor plate cast or wrought in the shape of a five-pointed star. Other names and styles of anchor plate include earthquake washer, triangular washer, S-iron, and T-head. In the United Kingdom, pattress plate is the term for circular restraints, tie bar being an alternative term for rectangular restraints.
