In slabs, the depth of compressed concrete is usually a small proportion of the slab depth and this means that it almost always involves only the concrete between the ball and the surface so there is no sensible difference between the behavior of a solid slab and Bubble Deck. No lsab are necessary for concrete mixture.

Voided biaxial slab

Bubble deck bubbleseck is composed of three main materials; they are steel, plastic spheres and concrete. The overall floor area can be divided down into a series of planned individual elements, up to 3 m wide dependent bubblledeck site access, which are manufactured off-site using MMC techniques. Bubblefeck total time from design inception to completion of structure was less than 12 months.

The voided biaxial slabs technology is directly incorporated in international standards as the Eurocodes, and various national codes such as the CUR in the Netherlands. 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.

Test results are as shown in Table 3[4]. This section possibly contains original research.

Lighter Stronger Precast Concrete Floor Slabs – BubbleDeck

Deflection of Bubble deck is 5. As a result, major projects around the world have chosen the BubbleDeck technology as the low-risk way to build large and complex projects. LV LIXf. If the applied shear is less than the bubbbledeck hollow slab resistance, no further check is required.

A major contributor to this article appears to have a close connection with its subject. Retrieved from ” https: This is only valid when considering the voided biaxial slabs technology. All of the BubbleDeck versions come in three forms- filigree elements, reinforcement modules, and finished planks. It may require cleanup to comply with Wikipedia’s content policies, particularly neutral point of view.

The reinforcement structure with spherical shapes and possibly a thin concrete shell as precast slab floor are supplied to the construction site in factory-made units with a maximum width of 3 meters; they are installed on site and are assembled by installing connecting rods and by pouring concrete as shown in fig 2.

The concept is based on the fact that the area between slabb of a solid slab has limited structural effect beyond adding weight. Of these types, only waffle slabs can be regarded to have a certain use in the market. The durability of bubble deck slab is not fundamentally different from ordinary solid bubbleddck. All the peculiarities of a project are therefore taken into account in the design; therefore there is no risk of the product being misused by applying it to uses for which it is not intended.

This is primarily a function of the fire resistance but is also relevant to durability. BubbleDeck is a precast concrete floor system which makes floor slabs lighter and stronger by incorporating large, hollow plastic balls in a lattice of steel. In any flat slab, design shear resistance is usually critical near columns. By using this site, you agree to the Terms of Use and Privacy Policy. Quick and easy to implement.

Unlike an off-the-shelf product, this is a system that is bespoke designed for each and every project. If the standard bubble material is used HDPEthe products of combustion are relatively benign, certainly compared to other materials that would also be burning in the vicinity.

The principal characteristic is that hollow plastic spheres are incorporated in the floor, Clamped in a factory-made bubblereck structure. The most effective weapons against vibration [4], particularly resonant vibration, are stiffness and damping.

This is not considered to be a significant weakness. It is a better situation than exists with inclusion of plastic rebar spacers within solid slabs that create a discontinuity within the concrete between the outside air and the rebar in solid reinforced concrete slabs.

August Learn how and when to remove this template message. Bubble Deck Slab Published on Sep 25, The Bubble deck slab floor system can be used for storey floors, roof floors and ground floor slabs.

BubbleDeck precast concrete floor slabs

Where deflections are large, bubbledec indicated by the static design, it is often an indication that the structure is Sensitive to vibration SLS issues. Investigations according to Eurocodes made at universities in Germany, Netherlands and Denmark, conclude that a voided biaxial slabs acts like as a solid slab.

In practice, the reduced shear resistance will not lead to problems, as balls are simply left out where the shear is high, at columns and walls. Joseph Moniera French gardener, patented a design for reinforced garden tubs inand later patented reinforced concrete beams and posts for railway and road guardrails.
