摘要： A system and method for anchoring a cold box structure of an air separation unit to a concrete foundation is provided. One such embodiment provides a concrete foundation having a plurality of reinforced concrete piers projecting vertically from a top surface of the concrete foundation and configured to anchor the cold box structure to the reinforced concrete piers using a plurality of horizontally disposed anchor bolts. Alternatively, the concrete foundation may include a plurality of hollow steel structures projecting vertically from a top surface of the concrete foundation and configured to anchor the cold box structure.

摘要： An anchor bolt assembly and arrangement for anchoring structure or equipment of an air separation plant to a reinforced concrete foundation is provided. The anchor bolt assembly includes one, two or more anchor bolts, each anchor bolt having a first end configured to be embedded in the concrete foundation and a threaded second end configured to be projecting from the foundation. The anchor bolt assembly further comprises a steel plate affixed to the first end of the anchor bolt(s) and extends in an orthogonal orientation to the length of the anchor bolts. The size of the steel plate is selected such that a perimeter of the steel plate is between about 0.25 and 4.0 times the embedment depth of the anchor bolt body which provides additional pull-out strength of the anchor bolt assembly. Preferably, the steel plate is disposed below to the bottom longitudinal reinforcement within the concrete foundation.
