Bricks, whether part of solid masonry walls or used as decorative facing materials such as brick veneer or stone cladding, play an essential role in the construction of buildings. Although solid masonry walls are considered structural walls, providing stability and support to the overall structure, brick veneer and stone veneer are primarily used for aesthetic purposes, adding a touch of elegance and sophistication to the building's exterior. While they may appear to be load-bearing, these veneers are actually attached to the structural backup walls, serving as a decorative layer rather than contributing to the structural integrity of the building.
What Are Bricks Connected With?
Bricks and blockwork are closely connected with masonry construction, forming the backbone of many structures. Whether it be a residential house or a towering skyscraper, this technique relies on the interlocking and adhesive properties of bricks to create sturdy and durable buildings.
Mortar acts as the vital element that keeps bricks and blocks bonded together. Composed of a mixture of cement, sand, and water, mortar solidifies over time, hardening and creating a secure connection. This binding material is crucial for both the structural integrity and aesthetic appeal of the masonry construction.
Furthermore, bricks and blocks are often reinforced with steel bars to enhance their strength and resilience. This reinforcement, commonly known as steel reinforcement, is inserted within the mortar joints or cavities, adding an extra layer of stability to the structure. Steel reinforcement is particularly important in high-rise buildings or structures subjected to heavy loads and forces.
In addition to mortar and steel reinforcement, bricks and blockwork are also connected with other construction materials. For instance, lintels, which are horizontal structural elements, are often installed above door and window openings to support the weight of the masonry above. These lintels can be made of steel, timber, precast concrete, or other materials depending on the specific requirements of the project.
Moreover, various cladding materials, such as timber, glass, or stone, can be attached to the surface of a masonry construction. In these instances, bricks or blocks act as the underlying structure, providing support and stability for the cladding while giving it an attractive appearance.
