Ringlock scaffolding stairway is used for the workers climbing up and down and also for the purpose of connecting the upper side and downside. More stable the ringlock scaffolding stairway is, the safer the whole system will be.

The standard erection height of the ringlock scaffolding formwork is less than 42m; if the erection height is more than 24m, another calculation shall be done accordingly.

If the ringlock scaffolding is used as the formwork frames, the line frame sizes of the standing tubes shall be calculated according to the real construction plan and choose the standing tubes, the adjustable base plate, and the adjustable head according to the erection height mixing pin.

If the erection height is more than 8m, the transverse diagonal tubes shall be fully planked and the space between horizontal tubes shall be less than 1.5m. Along with the ringlock scaffolding height, the diagonals on the horizontal floor shall be set every 4-6 sections.

The ratio of the total frame height and the width of the ringlock scaffolding shall be no more than 3.
