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.

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. Learn about the installation principles at page 45.

The properties of CRC i2® provide the architects with a freedom to express their creativity in both design and shape of the balconies. 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.

44 INSTALLATIONPRINCIPLES

We constantly develop new and innovative installation principles for our balcony projects. 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 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 and in the facade into consideration.

A2 CHEMICAL ANCHORS

The balcony plate is fixed to the 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 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 and 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. The moment from the cantilevered plate is transferred to the beam as torsion and from there to the support points where the beam must be restrained.

The principle makes it possible to have few support points, but this also means that concentrated forces must be hand- led at these supports. Consequently, the principle is best suited for new build where it is possible to plan and prepare for the reaction forces.

B1 PARAPETS AND STRUTS

The vertical load of the balcony is supported on brackets at the facade, whereas the moment is transferred into hori- zontal push/pull forces through either cast parapets, steel struts, or a combination of a parapet and a strut.

Parapets and struts can be designed in many ways, depen- ding on the requirements for assembly at different stages of building completion, structural capacity of the building and building parts, desired geometry and aesthetics, tolerances etc., so a specific solution is designed for each individual project. 0

48 C1 COLUMNS

The balcony is supported on a load bearing or brac- kets at the facade, and a number of columns depending on required supports and desired aesthetic expression.

If the vertical load at the facade is supported directly on a brick wall, the lateral stability must be ensured through brackets connected to the deck. In renovation, the back edge of the balcony is usually adjusted in thickness to match the brickwork, including tolerances.

C2 L-COLUMNS

The balcony is typically supported fully on L-columns, but can also be partially supported by brackets along the façade. The L-columns are placed with the columns either at the facade, or as free-standing columns at the front edge of the balco- nies. In both cases most or all vertical load is transferred to the under the L-columns. Because of this, the principle is often used for renovation or wooden buildings with limited structural capacity.

The columns can be attached to the building in different ways, depending on the specific situation for each project.

49 SELF-SUPPORTING C3 L- AND C-FRAMES

The balconies are supported by L- or C-shaped frames con- nected to the building. The frames are supported only by brackets at the end of the horizontal beam part of the frame.

For L-frames, the horizontal forces at the bottom of the co- lumn part is transferred to the building via the balcony plate, meaning that the L-frames must be supported by a set of temporary props until the balconies are in place. Lateral sta- bility is ensured via the balconies acting as stabilizing disks for both L- and C-frames.
