How to ensure your anchor installation procedure is safe
What does cracked concrete, failed jobsite inspections and carrying maximum loads safely all have in common? You guessed it - they’re all related to anchors. At Hilti, we provide solutions to all of them to ensure a safe and efficient anchor installation procedure.
In this blog, we'll explore these solutions - including our Adaptive Torque system, our SafeSet system, Eurocode standards and our HST2 anchor.
1. Adaptive Torque System
If you work with anchors daily, you'll know that over-torqued and under-torqued anchors are among the most common causes of failed jobsite inspections. Independent studies have also identified poor construction procedures as one of the main causes of structural failure.
It doesn't come as a huge surprise, especially when the tools available don't match the current demands. To correctly install an anchor, your choices are either a slow and imprecise torque wrench, cumbersome torque bars or a powered impact wrench, which lets productivity soar while safety and reliability slump.
But thanks to Hilti's anchor innovation, the Adaptive Torque (AT) system, you don’t have to compromise. The small, light interface slots in between the impact wrench and battery. It crunches live data from the SIW 6AT-A22 impact wrench to recognise when an anchor has been correctly installed. AT-ready tools are also equipped with the sensors and on-board intelligence to confirm if an anchor has been torqued according to ETA approvals.
SafeSet is Hilti's system for setting anchors and post-installed rebar connections. It helps to ensure that anchors can carry their maximum load values safely, minimising the risk of anchor failure. It’s also designed to speed up the installation of anchors and rebar connections, and to make them safer and more reliable. As with our Hilti AT module, all SafeSet components are covered by international approvals and work seamlessly as a system.
3. eurocode standards
The demand for cracked concrete approved anchors are on the rise. This is due to the development in the new design standards in which concrete is assumed to be cracked. This is where the Eurocode 2 part 4 can help.
This new standard consolidates, updates and replaces older design guidelines and technical reports (e.g. ETAG001, EOTA TR029) for fastener design. It's intended for structural and non-structural applications in concrete, and brings all aspects of fastener design together into a single standard. It also defines the design and specification rules for cast-in fasteners, post-installed mechanical and bonded fasteners and anchor channels.
4. Hilti HST2 anchor & cracked concrete
Our HST2 anchor offers a premium solution with an ETA for cracked concrete and a reliable solution with our AT module. With the changes in the Eurocode standards, the need for awareness around proper anchor design is more essential than ever. As the HST2 is integrated into the SIW Adaptive Torque module, you can rest assured that installation is safe - especially with the SafeSet reliability.
