Abstract
A temporary joint that includes a first discrete member having a first edge and a first movable coupling means; and a second discrete member having a second edge and a second movable coupling means. When it is necessary to form a joint between the first and second discrete members, the first and second edges are moved into abutment to define a binding edge. Then, the first and second movable coupling means are moved toward the binding edge; and the temporary joint is formed when the first and second movable coupling means are proximate the binding edge. The joint is broken by moving the first and second coupling means away from the binding edge. The first coupling means is comprised of a volume of a field responsive material and the second coupling means is a field producing means such as a magnet. A rigid joint is produced when the field producing supplies a field across the field responsive material.
