When your job is to repair the outside of a building or painting a wall you will need the right tool to roam safely in your work area. You need to get up to the highest point as well as the middle but you don’t want to hassle with moving a ladder around everywhere. You can create a scaffolding to reach as well as have more then yourself working in the same area.
A Scaffold is a temporary structure meant for holding workers and their tools, with materials, during the repair, decoration, or erection of a building. It can also be used as a suspended platform on skyscrapers and other tall buildings for window washers and painters. Scaffolding can tend to be expensive but will save a lot of time by giving access to multiple workers at different heights all at the same time. There are narrow scaffolding and rolling scaffolding as well. There are also scaffolding that support itself without being set up against a surface.
Scaffolding ladders consists of multiple materials to hold everything together. The three main materials that are used are tubes, boards/planks, and couplers. Other common materials used in a scaffolding ladder include ladders, sheeting, ties, base plates, ropes, gin wheels, etc.
Tubes are made out of aluminum or steel. The main difference between the two types of tubes is that aluminum tubes are lighter and have a greater flexibility. Coming in a variety of lengths with a standard diameter of 48.3 mm, tubes are usually bought in 6.3 m lengths, which can then be cut to a specific size.
Boards, or planks, are what provide the user with a working surface to walk on as well as place their tools and materials. The boards are usually wood with protected metal plates at the ends called either hoop irons or nail plates. Scaffolding planks are made out of wood, aluminum, or steel. The aluminum and steel planks have grates in them to provide a non-slip surface.
The fittings that hold all the tubing together of a scaffolding ladder are called couplers. There are three types of couplers that are used: putlog coupler, right-angle coupler, and swivel coupler. When you join the tubes together you use a joint pin, also known as a spigot, or a sleeve coupler. At times you use both the joint pin and the sleeve coupler.
If you are setting up your scaffolding next the a wall either on the inside or outside then you will need to use ties to help provide stability. There are different ties used for different situations. Box Ties are used to attach to pillars or like structures. If you have your scaffolding next to an opening or window then you will need to use Through Ties. Tie Rakers are single tubes that attach to a ledger extended out at an angle. Anchor Ties, also known as Bolt Ties, fit into holes drilled into the wall or structure. Reveal Ties rely mainly on friction and need to be checked periodically. They use openings with a tube wedged in. A reveal screw pin and protective packing at both ends hold the reveal tie in place.
