Purpose of a Lally Column
A lally column, also known as a steel support column or a basement pole, is a vertical structural element used to provide additional support for the floors, walls, and ceilings of a building. These columns are typically made of steel and come in different sizes and shapes depending on their intended purpose and the load they are designed to carry. The primary purpose of a lally column is to transfer the weight of the structure above it to the foundation, thereby providing stability and structural integrity to the building.
One of the main reasons for using lally columns is to help distribute the weight of the structure evenly. In buildings with large open spaces, such as basements and garages, lally columns are often used to prevent the floors from sagging or sinking due to the heavy load they have to bear. These columns are strategically placed throughout the area to help support the weight of the structure and prevent any potential structural damage.
Another important purpose of lally columns is to provide support for load-bearing walls. These walls are responsible for carrying the weight of the floors above them and transferring it to the foundation. However, in some cases, due to poor construction or shifting of the foundation, these walls may not be able to bear the entire load. In such situations, lally columns can be installed to provide additional support and prevent the walls from collapsing.
In addition to supporting the weight of the building, lally columns also play a crucial role in earthquake and hurricane-prone areas. These columns help to distribute the lateral forces caused by these natural disasters, thereby reducing the risk of structural damage and collapse. Furthermore, lally columns can also withstand high temperatures, making them an important safety feature in the event of a fire.
Aside from their structural purpose, lally columns also serve as a means of dividing the space in a building. By providing additional support, these columns allow for larger open spaces without the need for load-bearing walls. This is especially useful in modern architecture, where open-concept living spaces are gaining popularity.
Furthermore, lally columns also play a significant role in the installation of other building components. For instance, in the construction of staircases, lally columns may be used to support the weight of the stairs, handrails, and balustrades. Similarly, they can also be used to support beams and trusses, which are crucial for the structural stability of the building.
the purpose of lally columns is to provide additional support and stability to the structure, both during construction and after it is completed. Without these columns, buildings would be at risk of structural damage and collapse, putting the safety of its occupants in danger. Therefore, proper installation and maintenance of lally columns are crucial for the structural integrity and safety of any building.
