Construction workers have to carry out a variety of tasks that require elevation and platforms so that workers can get around building sites. Scaffolding is a framework build from steel and other materials that allows workers to reach the heights they need to perform construction and maintenance on building structures. There are many different types of scaffolding out there that are used for different purposes.
Single scaffolding is often used by brick layers. It is installed directly parallel to the wall and sometimes includes installing braces for additional support, especially at taller heights as this adds more stability to the structure. Braces are most often fitted with a cross diagonal brace.
Double scaffolding is often used by stone masons because it is stronger and more supportive. Double structure design features two rows of standard bars which are separated by ledgers for a more supportive structure. Double scaffolding is usually fixed to the wall and the floor and made even more supportive by cross braces.
Steel scaffolds are similar in appearance to mason scaffolds but instead of using bamboo or other timber materials the components are made out of steel. The structure is supported with holes in the walls surface. It is also often referred to as ‘tubular’ because of the hollow poles used in the structure. Steel designs are fastened together using steel couplings rather than rope lashings. The fastening mechanism used in these steel structures are put together with a range of steel components including nuts, bolts and washers. The steel scaffolds are fixed and welded to base plates which are anchored to the ground for a supportive and safe structure. Steel scaffolds have a range of benefits when compared to other types of structures and platforms; one of the primary advantages is that they can be put up and taken down really more efficiently than other types of scaffolds that use other materials such as timber. The other major benefit of steel scaffolds is that they are much more durable than other materials which makes them for more cost-effective over a long term period. It’s suitable for much greater heights than other types of scaffolds because it is sturdier Steel can be costlier than other materials like timber and bamboo however which means it can be a considerable investment initially. It also requires some maintenance to protect it.
Cantilever or needle scaffolds are supported by needles placed in walls. Cantilever scaffolds can be single or double designs. Single cantilever scaffolds are supported by a range of needles in the wall. Double scaffolds use both needles and beams attached to the floor to make a sturdy structure.
This type of design involves a platform which is suspended against a wall using ropes, pulleys, chains and wires. The suspended platform can be adjusted to different heights with these pulley systems. Suspended platforms are popular for painting jobs or cleaning and maintenance.
Trestle designs use a platform which is rolled around on moving ladders. They do not include any standards or putlogs so that they can be more easily move around. This kind of structure is most useful for repair work, cleaning, painting and other kinds of maintenance.
All kinds of scaffolding structures have different benefits and are valuable for different types of construction work and other projects. The type you choose will depend on a number of factors including what work you are planning to perform, what your budget is and what your long term goals are. If you’re planning a project you may want to think about whether or not you rent or buy.
