Voided biaxial slabs are reinforced concrete slabs in which voids reduce the amount of concrete. While concrete has been used for thousands of years, the use. Cobiax [1] slabs contain synethic void forming modules making slabs up to 35% lighter. This has a huge benefit for floor slabs in buildings as. efficient economic sustainable lightweight concrete slabs. Germany. Heinze Cobiax Deutschland GmbH. Otto-von-Guericke-Ring D Wiesbaden.

Design The Cobiax flat slab has the same mechanical load bearing behaviour as a solid flat plate slab. Considerably increased usability Columns and beams limit the design possibilities for the entire space.

At the beginning of every pioneering development, there are visionaries who turn theoretical possibilities into reliable technology. Possibility to gain floors at the same building height towers and building volume.

Voided biaxial slab

Moreover,the slab will not explode due to the escaping of over pressurised gas from the feet 4 feet for each formwork that act as safety valves. With Cobiax voided flat plate slabs, earthquake certification is easier; the reduced moving load is dynamically more tolerant than a conventionally designed building. Improved acoustic behaviour Thanks to the increased stiffness of the lower and upper slabs, acoustic transmittancy is decreased.

These elements comprise the top and bottom reinforcement mesh, sized to suit the specific project, joined together with vertical lattice girders with the void formers trapped between the top and bottom mesh slan to fix their optimum ckbiax. It may require cleanup to comply with Wikipedia’s content policies, particularly neutral point of view.

Economical and easy to transport, handle and store, also outdoors. S,ab slab, upper and lower.

Open spaces Larger spaces. Of these types, only waffle slabs can be regarded to have a certain use in the market. Due to the specific shape of the voids, there are no issues with internal pressure. But the use of concrete, with its high consumption of resources, can be usefully optimised by the implementation of intelligent voided building methods; the Cobiax technology even offers a biaxial loadbearing effect.

The Cobiax cage modules are positioned between the bottom and top reinforcement layers in the slab’s cross section where they also serve as supporting cages.

Voided Concrete Slabs

The overall floor area can be divided down into a series of planned individual elements, up to 3 m wide dependent upon site access, which are manufactured off-site using MMC techniques.

Lightweight construction with less mass is typically an advantage in seismic design. The concrete then flows into the correct static structure; the formers keep the voids open. Slimmer building elements The reduced load enables the use of more delicate, elegant building elements. No need for special steel chairs in Cobiax areas.

Focus has been on biaxial slabs and ways to reduce the weight. With its “Made in Germany” design, and the cobizx production and sales sites at various locations worldwide, the brand is setting a sign for its mission: Cobiax voided flat plate slab technologies are available worldwide.

This section possibly contains original research. The voids are positioned in the middle of the cross section, where concrete has limited effect, while maintaining solid sections in top and bottom where high stresses can exist. It also increases the level of acceptance of the building methods by neighbouring residents and institutions.

Investigations according to Eurocodes made at universities in Germany, Netherlands and Denmark, conclude that a voided biaxial slabs acts like as slav solid slab. So, construction companies, engineers, architects and builders can be assured that they will reap the benefits of the many advantages of Cobiax voided systems, without the slightest risk in terms of structural stability.

The architect is released from structural limitations and is able to plan more freely. Thanks to the limited weight of the Cobiax slabs, fewer columns are required; additional rooms, with all of the advantages of aesthetics and flexible use, are possible. What we mean by that? Benefits of the Cobiax flat slab technology The numerous advantages of the Cobiax technology lead to an increased value for all stakeholders involved in the design and exe- cution process of concrete structures cobiqx buildings.

Wider Scopes as an obligation Cobiax is more than just a brand.

Although this principle of material cbiax in statically unimportant areas of construction has been tried and tested for a long time, and is frequently used e. While concrete has been used for thousands of years, the use of reinforced concrete is usually attributed to Joseph-Louis Lambot in Articles with Italian-language external links Wikipedia articles with possible conflicts of interest from February Articles that may contain original research from August All articles that may contain original research All articles with vague or ambiguous time Vague or ambiguous time from August The fire resistance is dependent on the temperature in the rebars and hence the transport of heat.

Due to the reduced concrete volume, the shear resistance will also be reduced. It is a commitment to providing more room for cogiax for people, in the scopes and spaces in which they live and work.

The catch phrase “Wider Scopes” extends far beyond the possibilities for modern slab technology. Simple handling All of the Cobiax products are easy to lay; the Cobiax CLS technology considerably reduces the need for reinforcement. The CLS is coming soon!

The main obstacle with concrete constructions, in case of horizontal slabs, is the high weight, which limits the span. Slimmer slabs and walls A building that is lighter and slimmer overall, can be planned. Several methods have been introduced during the last decades, but with very limited success, due to major problems with shear capacity and fire resistance as well as impractical execution. Resource efficiency leads to increased static performance, economic costing and sustainable climate-friendly building structures.

Shape Retention Thanks to the reduced weight of the slabs, distortion of the ceilings themselves is reduced, and the building retains its shape better. Most attempts have consisted coniax laying blocks of a less heavy material like expanded polystyrene between the bottom and top reinforcement, while other types included waffle slabs and grid slabs.

By planning with Cobiax, architects clearly underpin their innovativeness and their commitment to modern, contemporary building methods.
