Definitions

  • bracing is normally required for the adjustable jacks to maximise the strength of the structure by transmitting calculated and notional shear forces to supporting foundations or anchorages and to maintain its rigidity.
  • the braces are secured at one end to a jack and at the other to an adjacent standard at a connection between that standard and one of the ledgers attached thereto.
  • Figure 1 shows the upper end of the screwed stem 2 of an adjustable jack connected to a standard of a scaffolding structure of the type described.
  • Carried on the screwed stem 2 is a channel-shaped support head 4.
  • the channel-shaped support head 4 may support shoring members, for example shuttering for use in forming concrete floors and the like.
  • the channel-shaped support head 4 is connected by welding, see 6, to a second smaller inverted channel member 8.
  • the second channel 8 is in turn welded, see 10, to a socket sleeve 12.
  • a locking member which comprises a shaped block, 36 or 38.
  • the ends of the C-shaped member 26 are elongated and formed with appropriately dimensioned slots 40 such that the shaped block 36 or 38, can be inserted therethrough and forced into a friction fit with the slot walls to retain the shaped block 36 or 38 in the slots 40.
