sWhen the erection height of steel tubular scaffolding with couplers complies with certain data, there needs no design calculation for tubes and rods. However for the tie members and standing tubes, the load bearing capacity of the ground

below shall calculated according real load bearing value and make according construction plan.

The design calculation of scaffolding shall be in accordance with relative calculations and requirements, which shall be approved and audited by technicians.

If the erection height of scaffolding exceeds 50cm, use double standing tubes to strengthen or bear the working load by parts, that is to say, use steel wire to pull the scaffolding and slab structure by parts along the whole height of the scaffolding and parts of the scaffolding working load can be transmitted to the building body.

And the working load on the scaffolding body can be passed to the obtruded cantilevered beams and frames. And of course, all these sharing load shall be calculated in advance.
