Hi-Con is specialized in creating solutions in high performance concrete for buildings where both a strong design and func- tionality is essential. The slender balconies from Hi-Con exploit the unique properties of high performance con- crete to create larger balconies with greater aesthetical possibilities than other materials. This brochure displays several Hi-Con references and installation principles to inspire you to create the balcony of your dreams. COUNSELING AND SHARING KNOWLEDGE IS ALWAYS A PART OF THE PROCESS When you choose a Hi-Con balcony, our knowledge and counseling is always a part of the process. That means that we put our specialized knowledge into play in every project to make sure to create a solution that meets the required design and specific installation principles for your balcony. With high performance concrete comes a plentitude of possible ways of combining function, aesthetic design and installation principles, and we are more than willing to assist you in this process. 7 Aahusene, Aarhus 8 ADVANTAGES WHEN USING HIGH PERFORMANCE CONCRETE Bigger balconies and thereby higher value Thin and minimalistic design Strength almost like steel Freedom in shape and aesthetic design 100+ years durability More daylight in apartments Maintenance-free and easy to clean surfaces Lower weight on building and larger balcony areas Smaller cranes needed for installation Lower transportation costs Fire resistant 9 10 A NEW GENERATION OF CONCRETE In 1986 the engineers at Aalborg Portland invented a new type of concrete with a com- plex mix of cement binder and steel fibers. They named the mix CRC: Compact Reinforced Composite The new concrete type - CRC - turned out to be extremely high performing in strength and durability. The concrete has a very little porosity and a high density, which makes us able to cast with a thin layer of concrete cover. The concrete also exploits the reinforcement more efficiently without breaking under extreme conditions. This means that a less amount of material is needed compared to conventional concrete. MATERIAL ASSURANCE Since 2001, we have continued to develop the concrete and today our generation of high performance concrete is the worlds’ oldest, best tested and documented high performance concrete. CRC has developed into a new generation of high performance concrete with same high material assurance, which we call CRC i2®, CRC i3® and CRC i4®. You can learn more about the material at our website or at our high performance concrete blog. 4 11 Huize Het Oosten, The Netherlands 12 BALCONYSLABS 3 The architectural dream of slender and minimalistic, cantilevered balconies are possible in high perfor-mance concrete. Hi-Con has supplied both new building projects and renovation projects with thousands of balcony slabs in high performance concrete. The minimalistic and extremely slender balcony can be made down to a thickness of 50 mm and, besides its aesthetical value, the balcony weighs less than a comparable balcony in conventional concrete. Often buildings can carry very large balconies of this type, which increase the value of the apartments and the applicability for the residents. LOTS OF INSTALLATION PRINCIPLES Balcony slabs can be installed in various ways.

The parapets can be designed in various heights and may function as a privacy screen. Furthermore, the parapets can be a part of the load bearing structure, making it possible to use hidden connections. The balconies are suitable for both renovation and new build.

This is only possible because of the extreme strength and durability of the material. The material properties make it possible to create bespoke balconies with the exact archi- tectural expression that you wish for. Whether it concerns slender, minimalistic balcony slabs or balcony boxes with a playful design, only your imagination sets the limits of the way Hi-Con can contribute to make your balcony dreams come true in high performance concrete. Balcony boxes can be installed with various principles.

In this way, we make sure that the balconies live up to the required design and technical aspects of the building. Whether the balconies intend to provide the residents with a new outdoor area or to repla- ce the old balconies, every balcony project is customized to meet your requirements. The installation of the balconies depends on the balcony type.

All solutions from Hi-Con are unique and the identification of the best installations principle is always a part of the design process. Three basic principles, which can be applied individually or together, are shown below: Principle A: Suitable for plane balcony slabs A1 A2 A3 A4 A5 Principle B: Suitable for balconies with parapets B1 Principle C: Suitable for balconies on columns C1 C2 C3 45 BRACKETS SUPPORTING A1 2 OR 3 SIDES The balcony plate is supported on brackets fixed to the load- bearing parts of the building, either along 2 or 3 edges. The plate may be partially cantilevered. The distance between brackets along the edges depends on the plate thickness, but is typically in the range of 2-3 meters. The bracket placement can usually be adjusted to take place- ment of windows and doors in the facade into consideration. A2 CHEMICAL ANCHORS The balcony plate is fixed to the deck via threaded rods con- nected to cast-in inserts in the balcony and glued into drilled holes in the deck. The method is only possible when the deck is sufficiently strong, and only for massive decks (not hollow core slabs). The number of bars needed depend on the size of the bal- cony and the structural capacity of the deck, but typically several bars per meter along the facade is required. This fixing method is normally only applied when other methods are not possible, primarily for renovation projects. 46 ISOKORB® A3 The balcony plate is supported on consoles (or plates) overlapping the deck within the floor build-up. It is only possible to use this connection when the floor build-up is 180-200 mm or more, and the consoles typically needs to be distributed relatively evenly along the facade, in most cases it is attempted to use window and door openings. The number and size of consoles depend on the balcony size and the load situation. A4 L- AND T- CONNECTION The back edge of the balcony is rotated 90˚up or down mak- ing an L-shape, or both ways making a T-shape. The resulting edge beam can either run the full length of the balcony, or be divided into smaller consoles. This beam is connected to the building via anchors, either chemical anchors or bolted connections via brackets. The anchors are normally distributed evenly along the beam, but can be grouped to accommodate for windows and doors. The required number of anchors depend on both the size of the balcony and its load situation, and the structural pro- perties of the deck, but typical numbers would be between 1 and 3 anchors per meter. 47 A5 TORSION BEAM The balcony is cast with an integrated beam along the back- edge spanning between 2 or more supports.
