K-STAGE STANDARD

Vertical axial load up to 57kN. The loadings will vary according to the horizontal loads taken into account and the actual extension of the jack required.

For standards at the beginning and end of a row, the loading figures for the top and base lifts have to be reduced by 5%, except if jack bracing is used. This also applies to the use of K-STAGE in towers and single bays.At least two lacing levels have to be used on each standard. When calculating horizontal forces, include wind forces, the effect of eccentricity, and out of plump (in accordance with British Standard 5975).Take care that the structure is stable in the unloaded condition, especially if towers or narrow structures are used. All standards should be erected plumb. Horizontal forces should be distributed over all standards as evenly as possible. Sound footings should be provided to prevent settlement of the standards.
