ANCHOR BOND JOINT BODY AND ITS MANUFACTURE

PURPOSE:To surely contrive the maintenance of the title body without varying an initial performance with the change in the lapse of time by a small number of processes by forming an overhang in a tip part of an anchor recessed part of a substrate, fitting and engaging an anchor of a clad plate to the anchor recessed part by pressure and joining them integrally. CONSTITUTION:On a base plate 1, longitudinal grooves 3, 3... of prescribed width are pierced through a prescribed interval, and lateral grooves 4, 4... of narrow width which have intersected with the grooves are pierced, and an anchor recessed part is formed thereby. In a bottom part of the anchor recessed part 3 of the longitudinal groove, an overhang-like anchor recessed part 5 of a mountain shape is formed along its longitudinal direction. On the lower face of a clad plate 2, projected parallels-like anchors 6, 6... against the anchor recessed parts 3, 4 of the longitudinal grooves and the lateral grooves of the base plate 1 are formed in advance integrally. The clad plate 2 is positioned in the anchor recessed parts 3, 4... of the base plate 1 by its anchors 6, 6... and both of them are pressed, and each anchor 6 of the clad plate 2 goes into the anchor recessed parts 3, 4... of the corresponding substrate 1 and is brought to plastic deformation, fitted and engaged, and the substrate 1 and the clad plate 2 are engaged integrally.
