Scaffolding

Scaffolding refers to the temporary frame structures used to help workers during various construction works. Construction of a tall building requires scaffolds to support people during the work process. Moreover, scaffolds are also used to carry building materials like cements and paints etc. One of the main advantages of scaffolds is that it can be easily dismantled after usage. Scaffolds should be designed on a particular structure as per the structural and performance requirements of different works.

 

Materials

Scaffolds can be designed using various materials. However, metal pipes are the most commonly used materials in designing scaffolds. In the case of Asian countries, scaffolds are also designed using bamboo. Metal tubes, which are made up of steel or aluminium, are available in different lengths. The next major accessory used in scaffolding is called coupler. The primary use of couplers is to hold the metal tubes together. Materials like base plates, ropes, gin wheels, and boards are also used to form a scaffold.

 

Design

A typical scaffold is made up of metal tubes, ladders, and other fittings. The height and structure of a scaffold depends upon the working level of a building. Construction works on very tall buildings can be done with the help of swinging scaffolds. A swinging scaffold is made up of a plank, which is hanged from the top of a building with the help of a strong rope strip. The swinging scaffold is designed in a secure way to avoid slipping. This type of scaffold is widely used for exterior construction works in very tall buildings.

 

Scaffolds that are constructed from the ground level are called pole scaffold. However, the lower ends of pole scaffolds are not placed on the ground directly. They are placed on a base plate, which spreads the load. The vertical tubes in a pole scaffold transfer the entire mass to the base plate. If the ground surface, where the scaffold is placed, is a concrete surface then there is no need for a base plate. However, base plates are always recommended to ensure safety. Guard rails in a scaffold allow a worker to perform his task without the fear of falling down.

 

Uses

Scaffolds are primarily used for commercial construction purposes. However, residential constructions also need scaffolds in some cases. Proper knowledge of scaffolding helps even non-professionals to perform minor works like painting, repairing and maintenance works. People who don’t have proper knowledge in scaffold construction should seek the help of a professional worker before constructing any scaffold.
