ABSTRACT:
Methods for manufacturing highly insulating connector rods and highly insulating composite wall structures using such connector rods. The connector rods are highly insulating and are injection molded in a single step from an appropriate resinous material or moldable plastic. Discontinuous fibers may be impregnated within the resinous material or other moldable plastic. The single step molding method yields connector rods having pointed ends for facilitating entry through an insulating layer and a first structural layer not yet cured, and also an enlarged head for receiving an impact from a hammer or mallet or for facilitating gripping by the installer. The enlarged head also provides an anchoring effect within a second structural layer upon curing. The connector rods are manufactured to include a ridge or flange to limit the depth of penetration by the connector rod when inserted into the insulating material when forming the composite wall structure. The ridge or flange also helps to prevent the collapse of the second structural layer towards the first structural layer after formation of the composite wall structure and implementation at a building site.
