BWC WB unit used with inner tube with angle

The system consists of several components:

BWC WB:
The BWC WB is cast into the precast wall element at the manufacturing plant and is installed flush with the external leaf of the wall panel.

Inner tube:
The inner tube is the component that connects the building structure to the balcony or access balcony element. It is available in several versions. The most common version is used in combination with a cast-in BWC 55-4 balcony box or supplied with a welded angle bracket.

Angle bracket:
The inner tube is supplied with a welded angle bracket and a steel dowel for supporting the balcony or access balcony element. The size of the angle bracket and the X-dimension are adapted to the specific project in cooperation with the structural engineer.

Function and Construction

All components are manufactured from S355 structural steel and are hot-dip galvanised.

Impact Sound Reduction and Thermal Break

Two integrated elastomeric elements between the inner and outer tubes reduce the transmission of impact and structure-borne sound through the balcony support connection. This contributes to good acoustic performance in the completed structure.

A thermal bridge is a part of the building envelope through which heat is transferred more readily than through the surrounding construction. Minimising thermal bridges is therefore important in energy-efficient buildings.

The integrated elastomeric elements provide a thermal break between the inner and outer tubes, reducing heat transfer through the connection.

Applications

The system can be adapted to a wide range of construction methods, including cast-in-situ concrete slabs, filigree slabs, hollow-core slabs and cross-laminated timber (CLT) floors.

In combination with our stair connection system, the solution can also be used where balconies are recessed into the building.

The system can also be adapted for refurbishment and conversion projects, for example where existing office buildings are converted into residential buildings and new balconies are required.

Fire Resistance

The solution can be supplied for fire resistance classes R30, R60 and R90, depending on the required fire resistance and the specified intumescent coating system.

Dokumentasjon og prosjektering

Teknisk dokumentasjon, EPD og BIM-objekter legger til rette for effektiv prosjektering, dokumentasjon og digital samhandling gjennom hele byggeprosjektet.

EPD-en gir tredjepartsverifisert dokumentasjon av produktets miljøpåvirkning gjennom livsløpet og kan benyttes som underlag for prosjektets bærekrafts- og miljømål.

Den europeiske tekniske vurderingen, ETA, dokumenterer produktets ytelse og egnethet for bruk i prefabrikkerte betongkonstruksjoner. CE-merket produksjon i henhold til EN 1090 ivaretar sporbarhet, produksjonskontroll og dokumentert kvalitet i samsvar med gjeldende europeiske krav.
