Do you ever wonder how repairs, cleaning, and additional construction happens on tall buildings? Well, after a building is erected, there is usually external construction right around it that sometimes resembles a crisscrossing ladder. This type of construction is called scaffolding. A scaffold is a temporary framework that mainly elevates and holds up manual workers and building materials during the construction, cleaning, or repairing of a high structure or machinery. It is usually made up of one or more boards whereby the size and length are relevant to the building. The planks feature different support methods that follow the form and purpose.
Now that we have introduced scaffolding, it’s time to understand the various scaffolds available and how to set one up.
Types of Scaffolds
There are eight different types available to suit various needs.
This type of scaffold is applied in brick masonry works and is sometimes referred to as the brick layer’s scaffolding. Its construction features standards, ledgers, putlogs, among others, and is parallel to the wall with a distance of about 1.2 meters between them.
Similar to the single type, double scaffolds are applied in stone masonry works. It features two rows of scaffolds placed side by side to create a more rigid and more stable frame and that’s why it is called double scaffolding.
Aluminum is known for being lightweight yet strong. This quality makes aluminum scaffolds widely held among construction workers as it promotes portability. Aluminum scaffolds are easily assembled and erected for use mainly during painting and cabling installation and also repairs.
Steel is the most popular type because of its security and endurance. This type is similar to single scaffolds with varying construction materials. Steel is used here, whereas in single, they use bamboo or timber to make the scaffolds. The reason why this type is preferred is that it is versatile and provides maximum safety at any given height.
This type is made up of galvanized steel which conforms to the shape of the current structure. This quality makes kwikstage ideal for various purposes. The main areas where this type of scaffolding works is in angular structures and directional bridges.
Also referred to as patented scaffoldings, scaffold towers feature steel construction coupled with distinct connectors and frames. This type is ideal for construction employees who work at heights with extremely high scaffold surfaces.
Here, the standards are held on a series of needles that get through the holes in the wall of the structure being constructed. Cantilever scaffoldings are usually erected when there obstacles in the way of the construction from the ground. It is not commonly used and thus requires proper checks before installing.
Trestle scaffolds are held on tripod-like mobile ladders. This type was mainly used in indoor repairs, electrical cabling, and painting jobs. Since it measures up to a 5-meter height, trestle scaffolding is limited to such short heights.
Design and construction of scaffolds
Scaffolds are important structures that support construction workers working on raised platforms. Therefore, the design should come from qualified personnel and be constructed carefully following the design. Its erection requires a talented individual who has sufficient preplanning to ensure maximum safety and usage.
Adequate preplanning entails choosing the type of scaffold for the job, knowing the maximum load it can hold, ensuring a good foundation and ways to prevent electrical dangers.
Scaffolds are essential structures for any construction and machinery work. It enables workers to reach greater heights and work efficiently. If you are planning to build your scaffold, it is important to consult a professional for better results and safety.
