American Frame scaffold is a type of construction scaffold first developed in the United States. It's also known as the portal scaffold, frame scaffold, or gantry frame.

Composition

The basic structure of the American Frame scaffold consists of gantry frames, cross - braces, connecting rods, hanging - type scaffold planks or horizontal frames, and locking arms. Additionally, horizontal stiffening rods, diagonal braces, base plates, end - plates, and jacks are installed. It is connected to the main structure of the building through wall - connecting members.

Advantages

- Easy to assemble and disassemble: Ordinary workers can assemble it by hand, with each part weighing no more than 20 kilograms, which is convenient for lifting, installation, disassembly, and transportation.

- Good load - bearing capacity: The vertical pipes directly bear the pressure, and the overall performance meets the construction requirements.

- Safe and reliable: It is equipped with various locking devices such as foot - pedals, parallel frames, wall - connecting pipes, and horizontal and cross - bracing pipes, which improve the overall stability. Moreover, being made of steel, it has good fire - resistance.

Applications

- Used as an internal or external scaffold for high - rise buildings.

- Serves as a support for formworks of floors and beams, and can also be used as a movable scaffold.

- Applied to the construction of various projects such as buildings, halls, bridges, viaducts, and tunnels.

- Can be combined with simple roof trusses to form temporary dormitories, warehouses, or sheds at construction sites.
