1. Scaffolding rods
The steel pipe fittings are made of galvanized welded pipes, and the end cuts of the steel pipes should be flat. It is forbidden to use steel pipes with obvious deformation, cracks and severe corrosion. When using ordinary welded pipes, the anti-rust layer should be painted inside and outside and repainted regularly to keep it in good condition.
2. Scaffolding connector
Malleable cast iron fasteners that match the diameter of the steel pipe and conform to the current standards in my country should be used. When cast steel and alloy steel fasteners are used, their performance shall meet the specified index requirements of the corresponding malleable iron fasteners. The use of unqualified, rusted and cracked fasteners is strictly prohibited.
3. Scaffolding Accessories
(1) The processing should meet the design requirements of the product.
(2) Make sure that the connection with the main frame members of the scaffold is reliable.
(1) All kinds of shaped stamping steel scaffolding, welded steel scaffolding, steel frame paneling scaffolding and various types of metal scaffolding processed by themselves, the dead weight should not exceed 0.3kN, the performance should meet the design requirements, and the surface should be It has a non-slip and water-proof structure.
(2) When using large-scale paving panels (such as plywood, bamboo slats, etc.), design and check calculations should be carried out to ensure that the load-bearing and anti-skid requirements are met.
