COBIAX SLAB PDF

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.

Improved acoustic behaviour Thanks to the increased stiffness of the lower and upper slabs, acoustic transmittancy is decreased. Also indicated for the top-down technique. In addition to the very easy and fast Cobiax elements distribution sitting on the bottom steel reinforcement, the construction implementation becomes much faster than any other slab system, this is due to the following facts: In cohiax, most of the concrete is used in the slabs.

Voided biaxial slab

Can be used together with prefabs. Cobiax voided flat plate slab technologies are available worldwide.

Newsletter 11 18 — Cobiax in every nook and corner November 13, Our November cobix has a new high-rise in Hannover on the topic. Properties Degradation Environmental impact Recycling Segregation in concrete Alkali—silica reaction. 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. With Cobiax technologies, these beam constructions are no longer necessary — building time is reduced and the building fobiax be put into operation sooner.

Cobiax voided flat plate slab systems enable larger areas to be spanned, at the same weight. For this reason major developments of reinforced concrete have focused on enhancing the span, either by reducing the weight or overcoming concrete’s natural weakness in tension. Major benefits would include: All these advantages, clbiax together, increase the profitability of the project considerably.

Therefore, Cobiax buildings regularly win international prizes for environment-conscious building. The Cobiax advantage for architects Greater design freedom Cobiax voided flat plate slab systems enable larger areas to cobkax spanned, at the same weight.

Slab thickness from 40 to 60 cm. Cobiax technologies avoid these limitations — they enable wider scopes, which offer completely new opportunities for use, as required. Georg Miedzik Managing Director. Click on the button below to register for our newsletter.

Slab thickness from 20 to 40 cm with one layer Up to 70 cm with two layers. No beams between pillars. Higher profitability In many cases, the limited depth required for the slab, means that more storeys become possible.

Joseph Moniera French gardener, patented a design for reinforced garden tubs inand later patented reinforced concrete beams and posts for railway and road guardrails. Read below about the types of Cobiax products and meet the advantages of our structural system.

Voided biaxial slab – Wikipedia

Beam solutions often require time-consuming intermediate steps during the building process. Xobiax concrete in the structurally relevant external zones of the cross-section and create as much internal voided volumes as pos- sible. Designing is consequently like for solid slabs, but with less load corresponding to the reduced amount of concrete.

Profiling Building with Cobiax always means making a commitment to future-oriented solutions in the area of resource conservation and sustainability. Retrieved from ” https: Cobiax at the Bau fair November 26, Our stand is located in Hall A1, the stand number is The main obstacle with concrete constructions, in case of horizontal slabs, is the high weight, which limits the span.

Construction terminology Floors Concrete. It may require cleanup to comply with Wikipedia’s content policies, particularly neutral point of view. All of the Cobiax products are easy to lay; the Cobiax CLS technology considerably cpbiax the need for reinforcement. Advances in building technology should never be at the expense of safety. Fewer dimensional limitations for the elements. Most attempts have consisted of 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.

No need for special steel chairs in Cobiax areas. Leave out as much concrete as possible whilst maintaining the full flexural strength of the slab and allowing a bi-axial load transfer. Columns and beams limit the design possibilities for the entire space.

The catch phrase “Wider Scopes” extends far beyond the possibilities for modern slab technology. The voids in the concrete slab, which is to be cast later, are inserted in the form of void formers or structural formers, both made out of plastic.

Voided Concrete Slabs

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. A two way spanning voided biaxial slab construction with spheres according to the BubbleDeck system, compared to older voided slab constructions:. Shape Retention Thanks to the reduced weight of the slabs, s,ab of the ceilings themselves is reduced, and soab building retains its shape better.

In practice, the reduced shear resistance will not lead to problems, dlab balls are simply left out where the shear is high, at columns and walls. In many cases, the limited depth required for the slab, means that more storeys become possible.

Reduction of columns section or their number. Lsab Leadership Trinity People History. While a true biaxial slab as the BubbleDeck system must be calculated as a solid slab, ribbed slab systems, like the U-boot system, consisting of a grid of orthogonal “I” beams, must be calculated as beams. As this floor type is made of complete prefab elements with no structural coherence, support moments are absent, resulting in increased material consumption. According to the contractor this may be caused due to the high temperatures during construction.

Reduction in the number of pillars. Never miss out on any news again.
