J&P Building Systems showcase H-BAU Products at Evolving Concrete

H-BAU Technik GmbH has been setting the standards in construction technology for over 35 years. Whether it is sealing, reinforcement, sound insulation, formwork or thermal insulation, the company provides innovative solutions for the highest quality demands.

J&P Building Systems showcase H-BAU Products at Evolving Concrete

On the 6th and 7th of May J&P Building Systems will be showcasing  both the RAPIDOBAT® Cretcon HD and ISOPRO®  from the H-BAU product range at the Evolving Concrete.

The ISOPRO® thermal insulation elements, types SBM and SBQ, are elements for connecting steel structures to reinforced concrete components.

The thermal insulation elements reliably provide positive locking connections of external components made from concrete with the internal components.

The RAPIDOBAT® Cretcon HD  is a disposable concrete column formwork which provides an unrivalled quality surface finish.

Evolving Concrete debuts at the Business Design Centre, Angel Islington, London on the 6th and 7th May 2015. This event will present a series of technical seminars on current topics for the Industry alongside an exhibition of companies, products and services providing the best that the concrete industry offers. Unlike other events both seminars and exhibition are aimed directly at the professional, in particular consultants, designers, specifiers, architects, architectural technologists and contractors.

Connections and Fixings – How to prevent heat loss between the internal structure and the external balcony

Balconies are frequently precast and then attached to a structure during construction. If measures are not taken to prevent it, there is a route for heat loss between the internal structure and the external balcony. This heat loss can lower internal temperatures such that the dew point temperature is reached and condensation occurs.

 How to prevent heat loss between the internal structure and the external balcony

The traditional method which was used, was to insulate the balcony (on both the top and bottom surfaces), and also to insulate areas of the slab within the structure. Current practice though is to incorporate a simple thermal break between the balcony and the supporting structure.

At the same time it is common to utilise a proprietary system to attach the balcony to the slab. There are several such systems available, two examples of which are below.

They all work in a similar fashion. There is an insulating layer, normally of polystyrene, typically 80mm wide. To take cantilever bending moments, there is tensile reinforcement in the top of the element, passing through the insulation. To prevent risk of corrosion, it is best practice for this tensile reinforcement to be stainless, although some systems use ‘normal’ reinforcement in a sleeve. Continue reading
