A COUPLING FOR INTERCONNECTION OF SCREW PILE PIPE COMPONENTS
A female connector has a body (31) having an internal bore (32) locating two annular, spaced arrays of four lugs (33) and open at one end to receive a male connector, the other end comprising a stepped mounting portion (35) including two spigot portions (36) sized to one or the other of CHS pile pipe ends and tapered lands (37) to which the pipe end may be welded. A reinforcing collar (40) tapers to the mounting portion (35), forming a land to which oversize CHS pipe can be welded. The open end (34) is stiffened by a further integrally cast external reinforcing collar. Transverse bores (45) provide for a tommy bar to apply torque by hand, or drive pins (not shown) securing the male and female connectors. A cast steel male connector has a substantially cylindrical hollow body having cast into its outer surface four shaped recesses into which the lugs (33) of the female connector may respectively pass until the respective lugs are adjacent opposed locating recesses. Thereafter, relative rotation of the connectors locates the lugs (33) in one or the other pair of the recesses depending on whether the pile is being driven or backed out. t) A -A Fig.. 4
