ABSTRACT:
Tie anchor for sandwich panels of reinforced concrete in the form of a metal strip of undulated zigzag shape whose loop portions are anchored in the concrete panel layers and whose connecting leg portions reach through the intermediate insulating layer. Two central leg portions of the tie anchor are oppositely inclined to form a rigid central connecting point between the panel layers, while all other leg portions are parallel, to allow for limited panel displacements, under unequal thermal expansion.
