1.1 the general design size
Scaffolding poling throw of 1.8 m (partial adjustments, but no more than 1.8 m), horizontal distance of 0.9 m (can be flat out three pieces of bamboo scaffolding, each scaffolding bamboo string width 250 mm), the bent frame interval of 1.83 m, the outer shelf step distance of 0.915 m (safety specifications for 6 m by 18 m, taut after slightly more than 1.8 m wide, such as double step distance of 1.8 m, safety net is not easy to tighten, appear loose, not beautiful, therefore, by the 1.83 m) of field experience, scaffold height limit 30 m (total height of 28.4 m and 28.4 m high barrier).Outer shelf inside a closed dense mesh net (300 per 10 cm by 10 c ㎡ hole).

1.2 longitudinal bar
Longitudinal scaffolding bar requirements set in the inside of the stud, length should not be less than three spans.
The appropriate extension use docking. Docking fasteners should be staggered, two adjacent longitudinal rod joint should not be set within the synchronization or with cross, out of sync or different across two adjacent joint in horizontal direction staggered distance should be not less than 500 mm, the distance form the centre of the joint to the master node recently should not be more than 1/3 of the longitudinal spacing.

Extension for lap, lap length should be not less than 1 m, should be equally spaced set three rotating fastener stationary.
This project use the ringlock scaffolding system, longitudinal rod should be as lateral horizontal rod bearing, with a right-angle fastener is fixed on the vertical bar.

1.3 lateral horizontal pole
Operation level of the main node of lateral horizontal bar should be according to the needs of supporting scaffold board spacing Settings, such as the largest spacing should be not more than half of the longitudinal spacing.
