  • the cross-piece 50 has a circular bore 51 aligned with the axis of the threaded member 47 but of lesser diameter.
  • a shouldered extension 52 of the threaded member 47 passes through the bore, and a collar 53 is retained on the part of the extension 52 which is on the side of the cross-piece 50 remote from the threaded member 47 by means of a grooved pin 54 that passes through a diametric bore in the extension 52 and co-aligned bores in the collar 53.
  • the collar 53 has an external diameter which is greater than the diameter of the bore 51. The portion of the shouldered extension 52 that protrudes beyond the collar 53 terminates in a square sectioned driving peg 55.
  • the arrangement is such that whilst the screw threaded member 47 can be rotated by means engaging the square sectioned driving peg 55, the screw threaded member 47 cannot move axially, since the collar 53 on the shouldered extension 52 retains the shouldered extension 52 on the cross-piece 50.
  • Means are provided for rotating the screw threaded member 47 at said housing 48, such as they handle or the like engageable with the driving peg 55.
  • the arrangement is such that the screw threaded member 47 forms part of a jack 31, and on rotation of this screw threaded member 47 the hollow member 36 supporting the soldier is driven along as a result of the engagement of the nut 46 embedded therein with the screw threaded member 47.
  • the movement of the jack 31 can be terminated at any desired position and the form or shutter will be effectively locked in that position since any forces tending to move the form or shutter 24 will not cause the screw threaded member 47 to rotate. If desired additional means can be provided for preventing further rotation of the threaded member 47, thus firmly securing the form or shutter in position.

  • the upper platform 4 and the support structure 7 may be assembled in position on the wall and the form may be lifted into position by crane (see Figure 6B).
  • the form or shutter is then moved forwardly across the platform to the desired position, the height of the shutter and the orientation of the shutter being adjusted by the various means described above. Then the shutter is utilised in the formation of a cast concrete wall, concrete being poured through the chute into the space defined by the shutter or form (see Figure 6C). When the concrete is at least partially cured the shutter is retracted by appropriate operation of the jacks described above enabling various finishing operations to be performed on the exposed surface of the wall (see Figure 6D). Subsequently the formwork is lifted up, the formwork subsequently being re-engaged with a fresh support plate embedded in or secured to the just cast section of the wall.
  • the formwork may be lifted by a crane, or may, as will be described in detail hereinafter, be a self-climbing formwork.
