Telescopic connectors or rolled steel angles which is the smarter way to install precast concrete staircases?
This study compares the costs of rolled steel angles (RSAs) against RVK 101 telescopic connectors to support precast concrete stair landings off core walls. When the costs of materials and labour were calculated, findings show telescopic connectors reduced man hours by 80%, contributing to a total 33% reduction in direct costs. Furthermore, robustness anchorage is inherent to the design layout, with no need for costly, supplementary measures typically required with RSAs. Other benefits of using telescopic connectors instead of RSAs include reduced waste, cranage and noise as well as increased safety, robustness, speed and efficiency.
