through the completed wall current plastic materials also develop great strengths permitting minimal cross sections thus minimizing further the heat transfer through the connecting device a first connector embodiment 1 of the connector constructed according to the present invention is seen in fig1 a 1 f connectors of the present invention are preferably used in creating wall and ceiling three ply panels having a first or face concrete layer thickness of about 2 3 u2033 an insulation ply layer of a thickness of about 2 u2033 to 6 u2033 and a second or structural concrete layer having a thickness of about 7 9 u2033 preferably the connector 1 has a maximum diameter preferably of about 0 35 u2033 to 0 40 u2033 most preferably about 0 377 inches and a length of about 5 5 u2033 to about 6 u2033 although these measurements may vary depending upon the type and size of the three ply wall or ceiling panel to be constructed or the thickness of the insulating material used in forming the same as illustrated the first connector 1 includes a first end 3 terminating in a point 5 the point 5 is constructed such that it is of sufficient sharpness to pierce and penetrate insulation board such as board marketed by dow under the blueboard tradename or commonly available insulation board marketed by dow and owens coming used in the construction of multi ply concrete walls the first end 3.
