<p>A pile joint to interconnect reinforcement elements 16 includes a male portion 20 insertable into a female portion 22, each portion having teeth 40 which mutually engage. The teeth are positioned such that when engaged they contact on one face, imparting a tension force; but there is clearance on the opposing face to allow the male member to move further into the female member and ensure there is no compressive force. There is preferably a lateral screw 78 to force the formations to engage. There may be a resilient gasket 28 between the bodies 24. Preferably the reinforcing members, and male portions are elongate and mutually parallel The direction of insertion is also preferably parallel while the teeth are preferably perpendicular. The reinforcement members are ideally for concrete bodies 24.</p> |
