The prior steps shall be prepared before the building of ringlock scaffolding
Key tubs OD shall be 60.2mm with a thickness of 3.2mm. All the tube material shall be Q345B except the ledgers and diagonals made of Q235.
Compared with other traditional steel tubular scaffolding, the ringlock scaffolding kind is simple in design, reasonable in structure, high load bearing capacity and sound stability. Their safety ratio is relatively high and easy to operate. It can be removed and built in a fast way and also adjusted its height to any random needs. The supporting frame has auto lock function which can make it hard to loose any elements or couplers. Finally, workers do not need any permission licenses to do any work for the ring lock scaffold systems.
The ground shall be tamped solid and smooth with an uneven ratio of less than 80mm. If the construction period encounter any rainy season, there shall be sound drainage measures to prevent any immersion of the ground because of any water accumulation.
