Kidwells Estate, on the outskirts of Maidenhead in Berkshire, is undergoing major regeneration involving seven new blocks, which are part timber clad and vary from three to six storeys of structural concrete frame. Long cantilever walkways that service multiple flats are a feature of the new development and the unusual design demands of the walkways presented a technical challenge.
The solution required a relatively unusual combination of products and Schöck resolved the various issues by designing in its Isokorb® type HP. It is a product utilised only if horizontal, tension and compression forces are present in the design and additionally it is necessary to integrate the Schöck Isokorb® types QP90+QP90 as well, for linear or point connection to support high shear loads. Schöck Dorn type SLD Q50 heavy duty stainless steel dowels were also incorporated to enable the transfer of vertical shear forces and allow two directional lateral movements at the expansion joints. The result was a completely secure thermally insulated load-bearing connection at all of the restricted, but key structural points.
