The detailed dimensions of disc-lock scaffolding involve several aspects, mainly including the dimensions of the main components such as uprights, horizontal bars (crossbars), and diagonal braces.
First, Uprights of Disc-lock Scaffolding
- Diameter: Uprights for disc-lock scaffolding mainly come in two sizes: 60mm and 48mm. Uprights with a diameter of 60mm are primarily used for heavy-duty support in bridge engineering, while those with a diameter of 48mm are mainly used in building construction and decoration, stage lighting trusses, and other fields.
- Length: Upright lengths vary, with commonly used lengths including 500mm, 1000mm, 1500mm, 2000mm, 2500mm, 3000mm, and 200mm. Additionally, there are uprights that can reach a length as long as 3130mm.
Second, Horizontal Bars (Crossbars) of Disc-lock Scaffolding
- Model Specification Module: The model specification module for horizontal bars is 300mm, meaning the length of the horizontal bar can be a multiple of 300mm, such as 300mm, 600mm, 900mm, 1200mm, 1500mm, 1800mm, 2400mm, 3000mm, etc. It should be noted that the nominal length of the horizontal bar is the distance between the axes of the vertical bars; therefore, the actual length is shorter than the nominal length by one crossbar diameter.
- Common Lengths: Depending on the nature of the project, the most commonly used horizontal bar lengths in formwork support scaffolding are 1.5m, 1.2m, and 1.8m. For working platforms, the horizontal bar length is generally 1.8m, with 1.5m and 2.4m used in combination.
Third, Diagonal Bars of Disc-lock Scaffolding
Specifications: The length and specifications of the diagonal bars are determined based on the length of the horizontal bars and the step distance (the distance between upper and lower horizontal bars). For example, the horizontal strut spacing of a formwork support frame is generally 1.5m; therefore, the height of the vertical diagonal bracing is generally 1.5m. For instance, the vertical diagonal bracing used on a 900mm horizontal strut is 900mm x 1500mm, and the vertical diagonal bracing used on a 1200mm horizontal strut is 1200mm x 1500mm, etc. However, in projects with particularly low load-bearing capacity, such as working frames or lighting frames, the strut spacing can be 2m, and the corresponding vertical diagonal bracing height is 2m.
Fourth, Other Components of Disc-lock Scaffolding
- Disc: The disc of a disc-lock scaffolding has eight holes, four small holes for horizontal struts and four large holes for diagonal braces.
- Adjustable Bracket: As part of the scaffolding, it is used to adjust the height, ensuring the stability and adaptability of the scaffolding.
In summary, the detailed dimensions of disc-lock scaffolding include the length and specifications of the main members, such as uprights, horizontal struts, and diagonal braces, as well as the specific dimensions of components, such as discs and adjustable brackets. These dimensions are designed to meet diverse engineering needs and ensure the safety and stability of scaffolding. In practice, the appropriate dimensions and specifications should be selected and erected according to specific project requirements and regulations.
