<p>A locking joint for joining first (10) and second sections (18) of a concrete pile comprises a metal plate on the end of each pile section and a metal skirt (130) extending from the metal plate on the first pile section around said pile section, and having an opening defined therein. A monocoque housing (12) made from folded sheet steel is secured behind the metal plate of the first pile section. The housing defines a base having an opening (48) therein coincident with an opening in the metal plate, and defines a second opening for receiving a wedge and aligned with said opening in the skirt. An outwardly projecting pin (16) projects from the metal plate of the second pile section and is received in a pin receiving space in the housing (122). The pin (16) defines an external flange or spigot at one end thereof. A wedge means (14) having a front end and a rear end, an upper face and a lower face and defining two arms and a slot (84) extending from said end front between the arms locates in the housing. Part of the upper face of the wedge means (14) adjacent the slot (84) firmly abuts the external flange of the pin (16) which passes through the slot means (84).</p> |
