What is the Kobiax roof?
rose roofing:Kobiax roof is a type of double-sided hollow concrete roof, which is also known as bubble roof or bubble deck due to the use of hollow plastic spheres in its structure.
Getting to know the Kobiax roof
Cubiacs roof or bubble deck slab is a new construction technology using hollow and flat slabs filled with plastic balls. This method can lead to advantages such as reducing weight, increasing execution speed, saving concrete consumption, and creating space in structures. From the information you provided, this method is a combination of different ideas and technologies in the field of construction. Kobiax roof is a type of modern roof with many advantages. This roof can be a good alternative to traditional block beam roofs. Choosing the right type of roof should be done according to the conditions of the project and with the opinion of the structural engineer.
The main components of the Kobiax roof
Plastic molds: These molds, which are known as Cubiax spheres, are produced in two types, flat and spherical, with different thicknesses, and form the empty space of the ceiling.
Rebar: upper and lower steel mesh that serves as roof reinforcement.
Steel holders: Used to hold plastic molds in place.
Pin rebar: They are used to connect the upper mesh to the lower mesh and create integrity in the roof.
Spacer: They are used to maintain the distance between rebars and plastic molds.
Concrete: Concrete is the main component of Kubiax roofs. Slabs are poured into the hollow spaces and provide the necessary strength to bear the loads and ensure the integrity of the structure in the roof.
Reinforcement: Reinforcements such as steel bars are used inside the Kobiax roof to increase the structural strength of the building. This reinforcement adds an extra layer of strength to the concrete.
Lower mesh network: The lower mesh plays an important role in connecting Cubiax modules to the roof or formwork system. The exact height of this net must be precisely determined during construction.
Kubiax module package: The basic and central element of the Kubiax roof is the black inflated modules that are spherical or egg-shaped. These modules are strategically placed inside the slab, providing both structural support and reducing the overall weight of the structure.
Upper Mesh: As the name suggests, the upper mesh is placed on top of the Cubix modules. It is connected to the underlying mesh using reinforcing rods and wires. The construction of this net is based on a predetermined execution plan.
The Kubiax roof combines the advantages of prefabricated technology and minimizes transportation costs by using pre-assembled modules that are placed in place by cranes. At the same time, it takes advantage of spatial structures and increases the overall strength-to-weight ratio of the structure. This innovative approach eliminates the need for efficient use of materials and provides benefits such as reducing concrete consumption, increasing construction speed, and improving spatial efficiency in building structures.
Advantages of Kobiax roof
Reducing the weight of the roof: Due to the use of plastic balls, the weight of the Kubiax roof is reduced by 35% compared to the traditional block beam roofs.
Increasing the span of the joists: Due to the double-sided performance of the concrete slab, longer spans can be used for the joists.
Reducing the grade of concrete: Due to the presence of plastic balls, the amount of concrete used in the Kobiax roof is reduced.
Increased seismic resistance: Kobiax roof is more resistant to earthquakes than traditional block beam roofs due to its two-way operation.
Sound reduction: Plastic balls act as sound insulation and reduce sound transmission in the ceiling.
Reduced vibration: Due to its integrity and double-sided operation, the Kubiax roof has less vibration than traditional block joist roofs.
Creating a passage space for facilities: The empty space between the plastic balls provides a suitable space for the passage of facilities.

Disadvantages of Kobiax roof
High initial cost: The cost of plastic molds and skilled labor increases the initial cost of the Kubiax roof.
The need for skilled labor: The execution of the Kubiax roof requires skilled and experienced labor.
Limitation in the thickness of the slab: the thickness of the slab in the Kobiax roof is limited.
Load carrying capacity: The load carrying capacity of the Kubiax roof is less than that of block beam roofs with heavy beams.
Possibility of damage to the balls: Plastic balls may be damaged during transportation and performance.
Application of Kobiax roof
Kubiax roof is used in various buildings such as residential, office, commercial, industrial, etc. This roof can be used in high spans as well as in earthquake-prone areas.
Office and commercial buildings
gyms
Industrial buildings
Residential buildings
Ports and bus stations
Green spaces
Exhibition halls
factories
Public spaces
The role of rebar in the roof of Kubiax
In the Kobiax roof, rebar plays a very important role in increasing the strength and strength of the structure. Some of the main roles of rebar in this type of structure are:
Tensile and bending resistance: due to its high resistance to tensile and bending forces, rebar ensures the necessary strength in the structure. This feature is of particular importance, because in the Kubiax roof, tensile and bending forces are among the forces that the structure must withstand.
Shock and vibration absorption: Due to its flexibility, the rebar has the ability to absorb shock and vibrations. This property of rebar can be effective against dynamic forces such as earthquakes and vibrations caused by environmental factors.
Strength and flexibility of the structure: By combining rebar with concrete, a unified unit is formed
