The raised floor is also known as a support, is a set of panels and supported by a metal cantilever frame.
The panel is made up of three elements:
- The first is the Upper covering or the walking surface (in porcelain stoneware and laminate, PVC rubber, PVC, rubber, and linoleum; parquet).
- Internal core (in 38 mm thick wood conglomerate or 30 mm calcium sulfate).
- Finally, a Lower balance of the aluminum sheet is used to protect the flow performance of the material from humidity.
All components are assembled, calibrated, and edged.
Even cantilever frames can vary with columns or stringers of different types. This allows the raised floor to support higher loads than the underlying floor. It can also be adjusted in height to reach the floor’s quotas, even at a height of more than one meter.
The technology and study have also led to the design of the construction system.
This type of floor’s effectiveness is the real key to its utility. Acoustic insulation Between the rooms that are separated from the attic and to allow for the possibility of inserting technical systems (telematics, electric, and for air treatment) into the sub-floor (plenum).
It allows for modularity and interchangeability, which makes it possible to inspect the entire environment down to the floor. This ensures that the systems can be maintained easily over time.
This application offers Multiple benefits during the construction of the building. It is ideal for use in commercial, executive, and data center areas, as well as restaurants and pavilions.
WHAT IS IT? HOW IT WORKS
The technical raised floors are designed to adapt to modern indoor environments. They can be used in any room that requires flexibility or adaptability, but they do not compromise the aesthetic and technical characteristics of porcelain stoneware.
These floors are versatile and can be used to alter the layout of rooms. They also allow for easy maintenance and reuse. There are many types of interior technical floors:
- Traditional raised;
- Raised self-standing;
TRADITIONAL RAISED FLOOR
It’s a pensile flooring system where the walkable area rests upon an elevated structure. Housing systems can be accessed from the technical compartment between the floor and the bottom.
A technical compartment between the floor and the bottom can be made that can house the systems. The subfloor supports the modules of the floor, making it easy to remove and allow access to the below.
TRADITIONAL RAISED FLOOR: ADVANTAGES
These are some of the benefits that this system offers:
- Flexibility in managing systems that move freely beneath the pavement.
- Accessibility of the systems allows for simplicity in maintenance operations
- Possibility to reuse. The ability to move individual panels or the entire flooring without adhesives is possible through dry laying.
- It can be used on any existing floor.
COMPONENTS & MATERIALS
Porcelain stoneware is attached to the structural core. The coupled material is repaired and worked to get a slight flaring to make it easier for you to lay and move the flooring.
Additionally, Support core two types of materials can be used: Calcium Sulphate or wood chipboard.
- Wood chipboard is ideal for medium loads and it stands out because of its affordability. Excellent mechanical and fire resistance.
- Instead, the Calcium-sulphate support can be used to achieve a panel thickness of 40mm. It is resistant to fire and humidity and has excellent sound absorption power.
The steel frame supporting the load-bearing structure is located above the attic. It is supported by circular feet with varying heights from 3-4cm to more than one meter, and connecting beams made of steel. To absorb noise and vibrations, the antistatic rubber is applied to the top of feet and crossbars.
SELF-LAYING RAISED FLOOR
It combines practicality and flexibility in maintaining raised floors. It is also possible to use the ceramic product without support. This allows for greater flexibility in modification and integration over time than traditional raised floors.
ADVANTAGES OF SELF-LAYING RAISED FLOOR
The system offers Benefits Such as:
- First, it is easier to install.
- Interchangeability of ceramic products
- Easy and quick flooring replacement
- There is also the possibility to use different formats.
COMPONENTS & MATERIALS
The system is composed of a porcelain slab of stoneware, to which is applied support made of special high-density compounds in recycled rubber and cork.
The rubber not only acts as a sound absorber but also increases the grip of sheets towards the structure underneath.
Under the stoneware slab is a support made up of a chipboard or Calcium Sulphate panel, encapsulated with two aluminum cores. The panel is laid on top of the aluminum foot and then fixed to it.
It is possible to make the following three materials.
The name is also used more often as a chipboard. It is made from recycled wood.
The monolayer of high density is made up of Plaster and cellulose fibers. It can be used in many thicknesses, including 28, 30, 32, and 34 mm, 36 mm, 38 mm.
At very high temperatures, the inert dough is made. Monolithic, homogeneous structure with a medium density.
This raised floor is very unique properties:
- Water absorption and dimensional stability are the first two.
- Noise reduction capability;
- Walkable comfort
- Fire resistance is the final option.
This property also depends on the structure and size of the molecular particles. The wood conglomerate’s wooden particles absorb more water and moisture than Calcium Sulphate. Instead, the X-floor is completely absorbent.
THE FUNCTIONAL LAYERS
Three main components are common to raised floors: Top finish, panel, and substructure
The top finish is generally made of porcelain stoneware and forms the upper layer on the walking surface. It is also the primary component of the system.
To ensure exceptional physical-mechanical properties, it is important to take into account the environmental characteristics and intended use when choosing a finish.
The slabs have a border to draw homogeneously between panels. This allows for better adhesion between panel and panel. It also cushions the stresses between the slabs and absorbs any thermal expansion.
The panel supports the slabs and has a structural function. It bears the load of the finishing slabs, distributing them to the structure below.
You can also choose from materials with different fire resistance and mechanical characteristics. This must be determined by your project’s needs.
It is also important to note the lower end of the panel. This protects the system from humidity and may improve its mechanical performance.
The substructure, made up of transverse columns or seals, has the purpose of supporting the walking surface. It also transfers the stresses to the underlying screed. This ensures the stability of the coupling of the structure and the panel.
COMPARISON OF RAISED AND TRADITIONAL FLOORS
The raised floor system is also more flexible than traditional floors. They can be rearranged to meet changing space needs by adding new workstations and modifying existing ones.
You can also use them to modify or maintain a system on one panel without affecting adjacent panels.
Additionally, because the components are dry, assembly and disassembly are much easier than traditional floors.
This flooring type also offers good thermal benefits. The thermal separation between the screed and the walking area results in a better quality of life.
It is possible to eliminate incompatibility issues between the raised and traditional flooring. This allows the designer maximum creativity.
Finally, raised floors can be considered as movable walls in economic terms.
The following summarizes the advantages:
- Practicality: Inspection and repair of the systems are possible at any hour without the need to use any masonry.
- Flexibility: The architectural project can be separated from the plant design.
- It can be used in a variety of environments, including on existing floors.
- Integrability with other technical finishes such as false ceilings and movable walls;
- High level of aesthetic customization. This includes the selection of the finish material and its colors, as well as the ability to create designs, brands, and decorative motifs upon request.
- Finally, many accessories can be used to customize the floor.
