Scaffolds are important equipment used in almost any construction project. They are essential for providing support and flexibility when working on repairs or construction of many different structures.
The type of scaffolding chosen will depend on the material suitability, the outreach and support provided, and the scope of the construction project. All scaffolds are made from basic elements that comprise the actual structure. When broken down to their basic components, scaffolds consist of 3 main parts.
1. The standards
The standards can be described as the core structural components of the scaffold. They consist of long pipes or tubes that extend along the length of the structure. They are the parts that connect directly to the ground and extend to the height of the scaffold. At the base of every standard is a base/support plate that distributes the weight of the scaffold evenly across the ground.
The standards are therefore the main weight-bearing components. The materials used to design the standards will determine the sturdiness and weight capacity of every scaffold.
2. The ledgers
Ledgers are horizontal poles that connect two standards and offer the primary platform upon which personnel and equipment will be supported. Ledgers also play an important role in overall weight distribution between two standard poles. The more ledgers that are placed between standards, the more platforms that can be designed for support.
3. The transoms
To provide further structural support to the standards, transoms are typically used. Transoms consist of shorter vertical pipes that are placed at a right angle to the ledgers. They work by providing additional support to the standards along the structure of the scaffold.
Transoms can either assist in holding the standards in place (main transoms) or providing additional support to the main transoms themselves (intermediate transoms). Intermediate transoms are typically used to hold up the scaffolding boards that serve as the primary platform for workers and equipment.
Braces and couplers
For scaffolds to be even more useful and safe on the construction site, additional structural elements are normally used. For example, braces run diagonally from the ledger to the standard in order to provide even more support to the scaffolding. Braces also serve the important function of preventing workers from falling over while working.
Couplers are flexible components that can attach to multiple parts of the scaffolding. For example, couplers can connect a transom to a standard to provide additional support when dealing with heavy loads. Couplers can also attach a ledger to a transom in a more stabilising manner to ensure structural integrity.
