According to the manufacturer, Bubble deck slab can reduce total project costs by three percent. Unlike Type A and B, it is a one-way spanning design that requires the use of support beams or load bearing walls. Daily and Weekly newsletters available. Also indicated for the top-down technique.
They are depicted in Figure Voided biaxial slabs are reinforced concrete slabs in which voids reduce the amount of concrete. If a false ceiling, lsab required it can be created faster. Email Address Email is required. The soffit has a flat surface that is ready to finish and does not require a false ceiling for aesthetic purposes.

BubbleDeck Type A is a combination of constructed and unconstructed elements. Retrieved from ” https: No beams between pillars.
The Bubble deck slab construction is following every usual criterion, and can be calculated according to usual principles. LV LIXf. The geometry of the BubbleDeck slab is identified by ellipsoids of a certain size, placed in a precise modular grid. BubbleDeck Type C is bubbleveck shop-fabricated module that includes the plastic spheres, reinforcement mesh and concrete in its finished form.
Savings in useful height on each level as bubbedeck are no emerging beams. Build More With Less BubbleDeck is the patented integration technique of linking air, steel, and concrete in a two-way structural slab. An early example is the Pantheon in Romebuilt AD. Stop worrying about your personal carbon footprint. This is only valid when considering the voided biaxial slabs technology.
Bubble deck slab is based on a new patented technique which involves the direct way of linking air and steel. A two way spanning alab biaxial slab construction compared to a traditional two way spanning non voided biaxial slab construction:. Bending stresses in the bubble deck slab are found to be 6.
Voided biaxial slab
Not only that, but most of the concrete that is in a slab isn’t even needed; it is just a spacer between the bottom, where the reinforcing steel is in tension, and the top, where the concrete is in compression. Hollow plastic balls are inserted into the slab and held in place by reinforcing steel. However required resistance can be achieved by providing vertical spab.
Since the weight of the structure reduced, this type of structure can useful to reduce bubbledecl damage. The concept is based on the fact that the area between columns of a solid slab has limited structural effect beyond adding weight. All tested buildings are proven safe, and are reopened. Deflection of Bubble deck is 5.
A two way spanning voided biaxial slab construction with spheres according to the BubbleDeck system, compared to older voided slab constructions:.
In the Bubbledeck system caused controversy due to the collapse of a parking garage at Eindhoven airport in the Netherlands. Open spaces Larger spaces. Add further savings from lighter structures, improved productivity and reduced energy consumption and it’s easy to see how using BubbleDeck preformed slabs can contribute to a healthy bottom line for construction projects.
Bubble Deck Slab | Seminar Report, PPT, PDF for Civil Engineering
Statements consisting only of original research should be removed. The principal characteristic is that hollow plastic spheres are incorporated in the floor, Clamped in a factory-made reinforcement structure. The practice of buying more books than you can read. There are a number of green attributes including; reduction in total construction materials, use of recycled materials, lower energy consumption and reduced CO 2 emissions, less transportation and crane lifts that make BubbleDeck more environmentally friendly than other concrete construction techniques.
If the applied shear is greater than the hollow slab resistance we omit balls and make it solid and then Check the solid part. The steel reinforcement is of grade Fy60 strength or higher. From Wikipedia, the free encyclopedia.
This page was last edited on 12 Decemberat In fact Bubble deck slab possesses a continuous mesh, top and bottom, throughout the slab and this ensures shrinkage restraint is well provided for and that cracking is kept to a minimum whether it is intrinsic or extrinsic cracking.
The system allows for the realization of longer spans, more rapid and less expensive erection, as well as the elimination of down-stand beams.
