Editor’s Choice Innovative Ancon rebar connectors used in iconic Russian skyscraper Helifix adds to its vast portfolio of Masonry Repair Details Structural repair specialist, Helifix, has recently made an addition to its extensive range of over 100 Repair Details, which give full technical and installation information on how to overcome a wide variety of structural faults. The new Repair Detail, RD WT35, gives guidance on how to connect a new timber frame to an existing masonry wall, when the new timber stud is erected within an existing masonry building and there is no access to install wall ties from the outside. This Helifix repair detail can accommodate large cavity width variations by using stainless steel RetroTies. Innovative and quick-to-install reinforcing bar couplers from Ancon replace time-consuming lapped joints and minimise reinforcement congestion in the gigantic concrete superstructure of Europe’s tallest building; the 87-floor, 462m high helicoidal Lakhta Tower in St. Petersburg. Every repair detail features drawings and provides details of the required products and tooling, specification notes and a step by step guide on how to undertake each repair using concealed installation techniques. The use of Ancon’s high- performance mechanical rebar coupling systems also helped maintain build quality. By eliminating lapped joints and hooked bar ends, Ancon’s couplers and headed anchors allowed the wet concrete to flow more effectively through the reinforcement grid during casting. The full range of Repair Details can be viewed, and individually downloaded, on the Helifix website at www.helifix.co.uk/ downloads. These fixings produce a secure mechanical connection in the masonry wall and are bonded into the timber frame with CrackBond TE resin. The site also contains full Helifix product information, brochures, applications, case studies and installation videos. Resulting in no external work or scaffolding required and the outer face of the wall left unmarked. Tel. 020 8735 5200 Email.
