All the bracing structure of the cantilevered scaffolding frame in such as the ring lock scaffolding systems shall be cantilevered beams made of style steel rather than the steel tube. All the structure shall be calculated for its anti-bending strength, anti-shearing strength, its total stability and its deflection strength.
The cantilevered frame shall be set on the horizontal beams and the anchoring points shall be located in the slabs on the main beams or the ones inside the main beams. It is forbidden to set on the protruded balcony or cantilevered planks. The manufacturing of the connection joints shall be in the structure of welding or bolt fastening to make sure the rigidity of the connection joints in any ringlock scaffolding system.
The connection methods of the bracing body and the whole structure shall be designed ahead and the take into consideration the connection parts material, as well as the fixation method of the connection components and the style steel. What are the most widely used are the round ring or the U bolt to meet the working load strength requirement in the ringlock scaffolding system. The connection of the normal bolt which bears the direct working load shall be connected with dual nuts and other measures to prevent any loose of any other bolts.
