Abstract

1444769 Bolts C I WILLIAMS 25 Oct 1973 [31 Oct 1972] 49784/73 Heading F2H [Also in Division E1] In a tie for concrete wall formwork, the tie rod 20 has screw-threaded ends and at least one central offset portion 29, the offset portion being arcuate with an inside radius of curvature 30 of from 4 to 6 times the rod diameter 38, and the maximum transverse extent of offsetting 32 being from <SP>3</SP>/ 16 to <SP>5</SP>/ 16 of the rod diameter. Preferably the former dimension is 4¢ times the rod diameter and the latter is “ of the rod diameter.
