All Your Questions Answered About Scaffold Towers
Scaffold towers have been in use for hundreds of years. But what are they, really? How are they put together? This article will explain the basics of scaffolding and scaffold towers.
Scaffold towers are temporary structures used when constructing or repairing a building. While many scaffold towers are not very tall, they can be as tall as needed, or attached to the building as high up as needed. It depends on the building, the work required, and the situation.
Scaffold towers have been in use for hundreds, perhaps even thousands of years. Any time a person needs to build something taller than they can reach, they have to stand on something. Ladders are okay, but they can be shaky and you have to constantly move them to reach another area. Scaffold towers can stay in place, allow the worker room to move, can be expanded or taken down as the job requires. Michelangelo used a scaffolding system when he was painting the ceiling of the Sistine Chapel. They have been used when making the world’s tallest buildings. And they were probably used when making the building right next door to you.
But how are they put together? Well, the basics of scaffold towers are made up of three parts: tubes (or pipes), couplers and the scaffold boards. That’s it. Sure, there are other parts, like base plates, sole boards, pulleys, ladders, ropes, etc. But the main parts of a scaffold tower are just those three things.
So, what are they? Well, the tubes are the long pieces of metal pipe that form the framework of scaffolding towers. They are made of either steel or aluminum, although in some Asian countries they use bamboo. Steel, while stronger, is also heavier and less flexible when being submitted to a force. Aluminum is lighter, and instead of breaking, will bend when being hit. Aluminum is often used these days for the tubes of scaffolding.
Couplers are what hold the tubes together. The main kinds of couplers are right-angle couplers, swivel couplers and putlog couplers. Putlog couplers are used to attach the scaffold tower to a building. If you are using a free-standing scaffold tower or a rolling scaffold tower, they will not be used. Right-angle couplers and swivel couplers are what are used when putting tubes into a position where they would take a lateral force or a load compression. Right-angle couplers of course hold the tubes at right angles to each other, while swivel couplers allow the tubes to be connected to each other at any angle. This is especially important when providing diagonal support.
Of course, the boards are what the workers stand on when working on scaffold towers. They are typically made out of wood, however, modern scaffold platforms made from aluminum, steel, and even composite materials are also gaining in popularity.
And those are the basic parts of what scaffold towers are made from. Of course, if you plan to use scaffold towers in your project, it would be a good idea to hire a professional who is knowledgeable in the construction and use of scaffold towers.
