Why use precast concrete beams and columns, in the first place? They have the most adaptable solution to the structural part of your project. Precast beams and columns can be used for a few applications. You name it, from parking designs to the structural groundwork of medium and/or high-rise commercial buildings. They are also the perfect solution for low grade parking situations. As a result, it can help wipe out the need for a parking lot Also, it scales down the size of the lot that is required. You can now make an optimal framework for projecting architectural and structural wall panels. You can also set the hollow core floor and roof plank with the beams and columns.
Basically speaking, here are a few things you need to know about beams and columns:
1. Beams
Typically, beams are considered structural factors and are out of one of the three key shapes:
A. Inverted tee beams
B. L beams
C. Rectangular
Beams are horizontal units that attend to deck members such as double tees, hollow-core, solid slabs and a few times to other beams. They can be fortified with either conventional reinforcing bars or pre-stressing strand. This will be contingent on loading conditions, the preferred production method of the producer or the spans.
The size is essentially any size. It depends on the need to fulfill the structural requirements. The depth is somewhere between 16 to 40 inches with a width of 12 to 24 inches. The span to death ratio is 10 to 20. Considering that beams are tossed upright, the bottom, ledges and sides are cast against a form. Regularly, it will give an as cast finish that turn into a polished and hard finish.
For the square and rectangular shapes, the columns are heaved in a horizontal position. 3 out of the 4 sides are produced with a form.
2. Columns
Customarily, columns are used to holds up beams and spandrels in applications like parking structures and precast concrete of all kinds. Most often, they are constructed as multilevel components varying from a single story to six levels. Maybe, even more. In order to please the architectural and structural requisites, shapes and sizes may vary.
In order to match the varying changing riser sections that they uphold, sizes can depend on its required structure. The width is somewhere between 16 to 24 inches. Once it finishes, three of the sides will have an as cast finish that turn into hard and sleek finish. The fourth side on the other hand is burrowed by the finishing crew to correlate the other sides as intently as possible.
