Frame scaffolding is a common type of scaffolding used on construction sites. It is assembled by connecting two sections of scaffold frame with cross sections of support posts, and workers climb the sections to assemble the next one. Pins and stud clips secure the sections together, and aluminum deck planks provide a surface for workers to stand on. The scaffolding also acts as a ladder for workers to reach their desired height, and ropes or electric hoists are used to lift materials. Frame scaffolding is typically rented from a construction supply or rental agency and delivered to the job site, but it is the construction crew’s responsibility to assemble and disassemble it.
Frame scaffolding is one of the most common types of scaffolding seen on construction sites around the world. Typically fabricated from round tubing, frame scaffolding comes in a variety of configurations, from one section that contains both a ladder and a walk-through portal to fully through sections and sections that resemble a ladder. The typical method of frame scaffold construction is to use two sections of scaffold frame connected by two cross sections of support posts arranged in a square configuration. Workers typically assemble the scaffold by climbing sections while carrying the next frame and post components with them. They then assemble the new section on top of the previous section that was built.
The pins emerging from the corner posts of a frame scaffold section fit into the recesses in the underside of the corner posts of the section being stacked on top of the lower section. Stud clips are placed across the connection to prevent the sections from coming loose. Aluminum deck planks or planks are placed across completed sections of frame scaffolding to give workers somewhere to stand while the next section of scaffolding is being assembled. The bottommost section of the frame’s scaffolding is commonly set on threaded mounts that include large wing nut adjusters. The scaffold is adjusted and leveled by turning these adjustment nuts until the desired angle or level is achieved.
The sections of the frame scaffolding not only provide workers with a place to work from, but the sections also act as a ladder for workers to reach their desired working height. Ropes hung from the topmost section of the scaffold provide a way for workers to lift materials up to their working level. Occasionally when working with heavy materials such as concrete blocks, an electric hoist will be employed to assist in lifting the materials. It is not uncommon to see workers performing tasks from multiple levels of a scaffolding tower at the same time.
Frame scaffolding is commonly transported to the construction site by truck. It is common for a construction supply or rental agency to provide the scaffolding for a given job. This is partly due to the sheer amount of scaffolding sections, cross posts and locking pins required for any given job which would be too expensive for a single company to purchase for the occasional job requiring the use of scaffolding. The rental agency will deliver the frame scaffolding supplies to the job site, however, it is usually the construction crew’s job to assemble and disassemble the scaffolding.
