Scaffolds have become a necessity in various kinds of projects. They are used during the construction and the maintenance phase. These days, multiple kinds of scaffolds are available. As a result, it becomes necessary for you to know about them so that you can make the best possible choice for your project.
The different parts of a scaffold
Here are some of the various components that make up scaffolding
- Standards: These are the vertical pieces of the framework.
- Ledgers: These are the horizontal pieces of the framework which run parallel to the wall.
- Braces: These are the diagonal pieces that either run or are fixing to the standards. They are used to enhance the robustness of the scaffolds.
- Put Logs: These are the transverse pieces. They are attached to the wall and the ledgers.
- Boarding: This is the horizontal platform which supports the materials and workers.
- Toe Boards: These run parallel to the ledgers, attached to put logs. They are meant to provide protection.
- Guard Rails: They are placed at the working level for safety purposes.
Now that you know about the basic components of a scaffold, look at its various types available.
This variety of scaffolds makes use of steel tubes. Generally, the standards are placed at 3m from each other. Steel tube is also used for the ledgers which are placed at distances of 1.8m generally. The diameter of the steel tubes can vary from 1.5 inches to 2.5 inches. Clamps are used for holding the tubes in different positions. Wedges, bolts, nuts, washers and clips are also used here.
The advantages of steel scaffolds
There are several benefits of steel scaffolds
- They are suitable for scaffolds that need to have a bigger height.
- They possess high durability and strength.
- They can be assembled with ease.
- The fire resistance is quite high as well.
The disadvantages of steel scaffolds
Here are a few of the cons of using steel scaffolds
- The associated costs are higher.
- You need to ensure that the steel tubes are painted to prevent corrosion.
- You need skilled labor for installing and dismantling the scaffolds.
This type of scaffolds is widely used for projects involving brick masonry. They are made of a single framework of standards, ledgers and other components. Here, the standards will have around 2m to 2.5m between each other. The distance between the wall and the standards are 1.2m approximately. The ledgers will be placed at intervals of around 1.2m to 1.5m.
This kind of scaffolds is a popular choice for stone masonry projects. Since holes for supporting put logs are difficult to come by, double scaffolding is preferable. Here, two rows will be created of standards. They are separated by means of ledgers. Generally, the first row will be located at 20cm to 30cm from the wall. The distance between this and the next row is 1m. To enhance structural strength and durability, transoms and cross braces are used.
Also known as cantilever scaffolds, they can either be of the single type or the double type. In the first case, a series of needles are used for supporting the standards. For double type, the projecting beam and the needle will be strutted through the floor via the openings. Needle scaffolds are generally used when the ground is not firm enough. They are also chosen when the project site is on busy streets.
Whatever type of scaffolding you choose, you should always hire and work with a reputed company. After all, you will want the project to be concluded safely and quickly.
