Because partition heads do not need to be carved around downstand beams or ribs, flat slabs are said to be faster and more cost-effective than other types of construction. Flat slabs can be constructed with an excellent surface quality to the soffit, permitting the use of exposed soffits. Beams are required if additional strength is needed (e.g., for supporting a roof), if the slab needs to fit into a pre-existing frame, or if aesthetic reasons require the use of carved wood.
The term "flat slab" applies to both interior and exterior slabs. An interior slab is one that is used as flooring while an exterior slab is one that is exposed to weather conditions. Most commonly, these slabs are made from concrete, but they also can be made from stone or another material.
The simplest type of flat slab construction has no beam at all. This is called a "partitioned" or "separated" slab. In this type of construction, walls are created by placing concrete blocks on top of each other and filling in the gaps between them with more concrete. These blocks serve as divider walls within the room, creating a separation between different areas such as cooking and eating areas. They can also be used as a support system for adding extra height to a room.
Flat slabs are ideal for most building and asymmetrical column layouts, such as floors with curved curves and ramps. The benefits of using flat slabs are numerous, including depth solution, flat soffit, and design arrangement freedom. Depth solutions are limited only by the slab's thickness and can include channels, recesses, or other features that help reduce wall surface area and increase interior space. Flat soffits provide a level surface over doors and windows that doesn't require special treatment (such as capping) and creates a continuous surface with the roof. Design arrangements freedom allows for more creative layouts without having to consider structural issues such as clearance under flooring or roofing, obstructions between rooms, or interference with mechanical systems.
There are two main types of flat slab construction: pre-engineered and custom-built. Pre-engineered buildings use standardized components that can be ordered by quantity and assembled on site by little more than a hammer and nail. This is usually the cheapest option unless you have a very large project or need unique design elements. Custom-built buildings require more time and effort but give you complete control over every aspect of the house. The designer/builder may work with a consultant or architect to develop plans for the structure of the home, its location, and its surroundings. Then they will select the materials for the house and have it built according to those plans.
Benefits of Flat Slab
| 1 | Flexibility in room layout. Partition walls can be placed anywhere. Offers a variety of room layout to the owner. False ceilings can be omitted. |
|---|---|
| 6 | Prefabricated welded mesh. Standard sizes Less installation time Better quality control. |
| 7 | Auto sprinkler is easier. |
The flat slab is simpler to build and requires less formwork. Concrete flat slabs are classified into four types:
Applications for Flat Slab:
Flat slabs are commonly utilized in parking garages, commercial buildings, hotels, and other locations where beam projections are undesirable. They are also used as flooring in home remodels or when a flat surface is needed.
Beamless construction allows for more spacious rooms, while still providing support for heavy furniture or equipment. This type of building is especially useful for offices, laboratories, storage spaces, etc. Beamless structures are becoming increasingly popular, particularly with the rise in micro-living. These properties reduce the need for doorways and windows that take up space and increase the risk of theft. Instead they use structural members at right angles to each other to create a box like structure.
Beamless homes can be built utilizing wood, metal, or concrete. The most common materials used for this purpose are steel and aluminum. These elements are usually joined together with screws or welds. Their main advantage is that they provide much-needed support for ceilings and floors without obstructing traffic flow through the house. However, they do add some weight to the building which could affect its stability in an earthquake.
The beauty of beamless designs is that they allow for open plan living. This means that there are no walls separating different areas of the house, only open space.
A level slab is secure. Safe in the sense that the slab is designed to be fit for the intended function. One critical factor to consider when building a flat slab is punching shear. The punching shear resistance of a slab diminishes as slab thickness increases (bear that in mind when designing). Picking a good quality slab and applying adequate reinforcement where necessary will produce a functional and safe surface.
There are two main types of slabs: concrete and stone. Both are easy to cut, but stone is more durable if exposed to sunlight or moisture. Concrete remains flexible even after it has hardened and can be worked like wood. It's suitable for outdoor use where there is risk of water damage.
Concrete slabs are usually 4 feet by 8 feet or larger. They are placed on a reinforced foundation and need to be thick enough to withstand the weight of vehicles driving over them. Thin slabs are not recommended because they are prone to cracking under pressure from tires. Thicker slabs are safer because they will absorb some of the force of an impact instead of transmitting it directly to the foundation.
The best option for a flat slab is a pre-cast product. These come in standard sizes and are manufactured in controlled environments with strict quality standards. They are strong, long lasting, and affordable. Pre-cast products also require less maintenance than natural stone or brick and can be used outside if needed.
