RCC (Reinforced Cement Concrete) band in brickwork is a horizontal layer of reinforced concrete that is laid on top of the walls of a building to strengthen them and distribute the load evenly. It is usually placed at the plinth level, which is the level of the ground on which the building rests.
Importance of RCC band in brickwork
Strengthens the building
It provides additional strength and stability to the brickwork, making the building more resistant to external forces such as wind, earthquakes, and settlement of the foundation.
Improved structural stability
It provides additional support and strength to the building, which can help to prevent collapse during an earthquake.
Even load distribution
It helps to distribute the load of the building evenly across the walls, reducing the chances of localized stress and damage.
Prevents cracks
It helps to prevent cracking in the brickwork by reinforcing the walls and providing a strong, continuous layer of support.
Enhances durability
It improves the durability of the building by protecting the brickwork from damage and deterioration due to moisture, temperature changes, and other environmental factors.
Increases safety
By strengthening the building, these bands can help to increase the safety of the occupants, reducing the risk of injury or damage in the event of a structural failure.
Design Considerations for RCC Bands in Brickwork Construction
Here are some of the key design considerations of these bands in brickwork construction:
Load Requirements: The size and spacing of the reinforcement bars (rebars) used in the bands depend on the load requirements of the building. The load requirements are calculated based on the weight of the building and the expected loads, such as furniture, occupants, and environmental factors.
The thickness of the RCC Band: The thickness of the band also depends on the load requirements of the building.
Generally, the thickness of the band should be at least 100 mm or as specified in the design.
Size and Spacing of Reinforcement Bars: The size and spacing of the rebars used in the band depending on the load requirements and the thickness of the band.
As a general rule, the minimum diameter of the rebars should be 10 mm, and the spacing between the rebars should be between 100 mm to 150 mm.
Quality of Materials: The quality of the materials used in the band is crucial to its strength and durability.
The concrete should have a minimum compressive strength of 20 N/mm², and the rebars should meet the requirements of the relevant codes and standards.
Placement of RCC band in brickwork
The thickness of the RCC Band: It should be 100mm thick to provide adequate support to the brickwork.
These bands are provided below the windows and above the windows and doors in brickwork construction.
