Definitions

  • This invention concerns the design of a head that is fitted onto a pile to give vertical and/or angular adjustment.
  • Piles are used to support wide varieties of structures including domestic property, commercial buildings, industrial buildings, bridges and temporary structures. If the foundation to be supported is cast insitu in concrete, the finished level at the top of the pile and the plumb of the pile is often not critical, as the concrete foundation is cast around the pile. In other applications, such as temporary buildings, piles are often used to support a prefabricated grillage of beams. In these applications it is important that the finished top of all the piles are set to the correct level and plane.
  • the present invention has been made from a consideration of the foregoing.
  • an adjustable pile head for a pile.
  • the pile head may be angularly adjustable.
  • the pile head may be vertically adjustable.
  • the pile head may be locked in an adjusted position.
  • the invention also provides a pile having a pile shaft and an adjustable pile head according to the preceding aspect of the invention connected to an upper end of the pile shaft.
  • the pile head comprises an upper or first member and a lower or second member.
  • the members are configured so that the members can move relative to each other to provide angular adjustment of the head of the pile.
  • opposed surfaces of the members may co-operate to provide angular adjustment of the head of the pile.
  • the angular adjustment to the head of the pile can be achieved by relative rotation of the upper and lower members.
  • angular adjustment can be achieved by rotating the upper member, that preferably has an outer part ball shaped surface, inside the lower member, that preferably has an inner part cup shaped surface complementary to the outer surface of the upper member.
  • the opposed surfaces of the upper and lower members are part spherical. In this way, the opposed surfaces form a ball or swivel joint and the upper member can be rotated to provide angular adjustment of the pile head in all directions.
  • means is provide to lock the members in an angular adjusted position. In this way, the pile head can be fixed in the angular adjusted position.
  • the locking means may fix the angular adjusted position temporarily or permanently.
  • the cup and/or ball shaped members define a hollow section within the pile head and the pile head is preferably infilled to give a firm foundation for fixing the supported structure.
  • the infill material can also be used to lock the cup and ball shaped members together in the angular adjusted position and prevent movement of the finished top of the pile.
  • the infill material is preferably flowable to fill the hollow section of the pile head and hardenable in situ. In this way, the pile head forms a solid cap at the top of the pile.
  • the infill material may be grout, concrete, resin, glue or any other suitable filler.
  • the inside of the cup and ball shaped members may be provided with one or more formations such as ribs. Where provided, the ribs may strengthen the co-operating surfaces and/or may assist locking the members relative to each other when the pile head is infilled.
  • the cup and ball shaped members may be locked together by any other suitable means such as one or more screws, locking pins or the like.
  • Such means may usefully be employed with infill material to prevent the cup and ball sections moving while the infill material is added and/or before the infill material has hardened.
  • the pile head is positioned on a pile shaft.
  • the lower member of the pile head and the top of the pile shaft are configured for relative movement to provide vertical adjustment of the head of the pile.
  • coupling parts of the lower member and pile shaft may co-operate to provide vertical adjustment of the head of the pile.
  • the vertical adjustment to the head of the pile can be achieved by rotating the lower member, that preferably has a screw threaded portion, relative to the upper end of the pile shaft, that preferably has a mating screw threaded portion.
  • the upper end of the shaft may be screw threaded for co-operating with a matching screw thread on the lower member.
  • the upper end of the shaft may be provided with a threaded member for co-operating with a matching screw thread on the lower member.

  • the locking means may fix the vertical adjusted position temporarily or permanently.
  • a threaded nut may be provided to lock the lower member relative to the upper end of the pile shaft in the vertical adjusted position.
  • the lower member may be locked relative to the upper end of the pile shaft by any other suitable means such as the infill material used to lock the upper and lower members of the pile head together.
  • the upper member may provide the pile head with a flat upper surface.
  • the upper member may be adapted for connection to a structure supported by the pile, for example the upper member may be provided with one or more holes for attaching bolts to fasten the structure to the pile.
