Now known as Parklands, this landmark £27.1 million project is a scheme for One Housing and replaces seven 1960s built apartment blocks. Long cantilever walkways service multiple flats and the unusual design demands presented a technical challenge for Schöck, who supplied the structural thermal breaks. The design required as much natural light as possible in the areas around the walkways, so extensive light wells are introduced at regular intervals along the length of the galleries – effectively a series of elongated spaces, separating the walkways from the building for large sections. This means far fewer structural connection points between the walkways and the building than would normally be anticipated. The walkways are cantilever concrete construction into internal reinforced concrete frame; and because of the restricted connectivity point opportunities, the Schöck structural thermal breaks had to resist a much greater shear load than would be the case with a more conventional design. Schöck resolved the various performance issues by designing in its type HPC Isokorb. It is a product utilised only if horizontal, tension and compression forces are present in the design – and it is necessary to integrate the type QP90+QP90 Isokorb as well, for linear or point connection to support high shear loads. The result was a completely secure thermally insulated load-bearing connection at all the key structural points. The Schöck Isokorb range provides BBA Certification, LABC Registration and meets full compliance with all relevant UK building regulations.
