Whitepaper: BALCON Thermal efficient balcony connection system

Whitepaper BALCON Hybrid Channel Solution

21/11/2017 – NEWS – J&P Building Systems publish whitepaper on their concrete balcony connection system and the development of their thermal breaks.

Continual product development of our thermal breaks whether steel to steel or for our concrete balcony system has led to some interesting results that will benefit our customers. Thermal breaks can be a bit of a “black box” subject, but at J&P we are here to shed some light on this subject for our customers. so that they obtain the correct advice when it comes to thermal breaks.

Whitepaper BALCON

The BALCON unit is a versatile assembly for joining metal balconies to a concrete structure.  Simplicity is the theme behind the design of the BALCON, from the installation stage through to the connection of the balcony by follow-on trades; making the BALCON useful and easy for all who need to work with the unit.

The BALCON is strong; meaning fewer connections are required to make sufficient structural fixings. It is a rigid fixing point; with no rotation, allowing the designer to focus on the supporting steel structure.

Tolerances add to the toolkit of benefits offered by the BALCON allowing follow-on trades to fix easily to the BALCON. Concrete tolerances are higher than those expected by the balcony manufacturer: the BALCON enables these trades to work in harmony, reducing the risk of site works that cost time and money.

The poor detailing of a thermal bridge can contribute to significant heat loss through the façade. The BALCON can assist in the reduction of heat leaks by reducing the impact of these losses. This is because there is potential for reducing connections through the façade where a FABREEKA_TIM shim adds to the thermal break.

So now you know BALCON, why not make it your next connection of choice?

JORDAHL® Toothed Straps

JORDAHL toothed straps JVB-V and JVB-N are excellent product choices when connecting precast concrete elements such as columns and walls with each other.   

In combination with JORDAHL® anchor channels and T-bolts, they form an ideal fastening system for the efficient alignment of precast elements in a 3D space. Installation is easy, and the adjustable connections compensate for the manufacturing and placement tolerances of the concrete components.

JORDAHL® toothed straps also support high loads in two directions, while a sliding connection to the JORDAHL® anchor channel allows vital differential movement between components in the third dimension. The software allows load bearing capacities to be verified analytically with accuracy. Consequently, the combined system represents a powerful, cost-effective and completely verifiable alternative to conventional connections.

  • Toothed straps JVB-V: for shear load connections, for example: precast panel connections
  • Toothed straps JVB-N: for tension load connections. Adjustment range ± 38mm
  • Fast, efficient and adjustable connections between precast concrete components
  • Differential movement between components combined with high load capacities
  • Very cost-effective
  • Easy positioning and alignment of precast concrete elements
  • Cast-in anchor channels add to the ability to compensate for construction tolerances
  • No welding on site required
  • Suitable for thin concrete components
  • Fast and easy installation
  • Connection recess does not need to be filled with mortar
  • Complies with fire safety requirements when used in conjunction with fire lagging rope and mortar
Easy Adjustment for Construction Tolerances while Supporting High Loads
  • Accurately adjustable connections
  • Extremely resilient interlocking of strap components
  • Easy alignment of precast concrete elements
  • Connections support loads up to 17.2 kN
  • Straps can be fully loaded immediately after installation
Design Reliability
  • Secure fastening based on Eurocode-compatible design concept
  • Fully verifiable load capacities aligned with the performance of matching anchor channels
  • Free design aid with all the important information for design and product selection
