How to add reinforced concrete columns to an existing building
Reinforced concrete columns are mostly utilized to carry plenty of a building. They move these loads appropriate safe soil bearing capacity. Occasionally a building might have only the load bearing walls. These structure might not safely carry an extra floor above. The house could also require a roof differ from light weight materials like galvanized iron sheets to the heavier concrete or clay roofing tiles. These will warrant more bracing of the unit to carry these extra loads.The reinforced concrete columns in a building could be finished using plaster render, cladding’s or left using the concrete color. No matter the finish, it will give good aesthetics to the wall facades. These columns might be erected free standing or within the building fabric. They might have the usual rectangular or square form, though it might also have the circular form. It is very important to measure the factors where to erect columns. This is to ensure that all the required supports are put in place before any cuttings are carried out safely.
The method of adding reinforced concrete columns, is by marking out all the points to add columns. The walls and roofs are supported making use of props and bracing. The columns ought to be place at all building corners and any load bearing walls intersections. The wall is cut carefully up to the beam the beam level. Concrete at the roof beam level is hacked and taken out to expose the reinforcement. The wall opening must have a masonry toothing. A pit is excavated for the foundation base and column starter bars. The base and the column is then cast and vibrated nicely.
The column starter is treated after 7 days. Extra reinforcement is put into the roof level and joined using the beam steel. Hoop iron is done at alternate courses passing through the steel from both wall ends. This is to permit the wall to become strengthened after the cutting. Form work is then carried out. Concrete is cast and vibrated. The form work is taken out after seven days of curing. The procedure is repeated at every point where are going to a reinforced concrete column. The appropriate finish is then carried out to fit with the existing wall surface facades.
