Compliant Design | Approved Product | Proper Installation
Post-installed rebar can be used to build most connections on site – for instance, walls, slabs, beams, foundations or supporting columns. The full process can be tedious and time consuming but you can overcome these challenges with our end-to-end solutions for a safer and more reliable installation. Our solution starts from design to meet local regulations, selecting the right products and installation with the latest technology for increased performance and productivity.
Post-installed rebars are used to connect two concrete members and is an essential application in building construction and infrastructure projects. Rebars become part of the structural system and must be designed as carefully as the entire structure. While European Technical Approvals prove that in basic load situations, post-installed rebars behave like cast-in bars, number of differences needs to be considered in special design situations such as fire or load cases where hooks or bends would be required for cast-in anchorages. The task of structural rebars is to take tensile loads and since concrete failure is always brittle, reinforced concrete design assumes that concrete has no tensile strength. Therefore despite the application, all rebar applications must be designed.
IMPORTANCE OF DESIGN
COMPLIANCE
Local rules, codes and safety regulations – your correct and compliant specification is a top priority. Our ready-to-implement specification note can be plugged into your rebar specification to help ensure code compliance and help guide your jobsites' installations.
OPTIMIZATION
Let's face it, Eurocode does not cover all 'jobsite realities'. So we've developed the HIT Rebar method, and designed several solutions for post-installation rebar builds, which include concepts to overcome the limitations of structural concrete codes.
SAFETY
Different elements have a direct impact on the quality of the installation. Such as, but not limited to cleaning, minimum concrete cover, scanning for existing bars, roughening of concrete, injection accessories and drilling aids.
Now you can design and install 'post-installed' rebar connections with more confidence. Inadequately cleaning holes during installation can reduce the performance of conventional chemical anchor systems significantly. Hilti SafeSet™ Technology eliminates this factor almost entirely – in both cracked and un-cracked concrete with post-installed rebar.
What is the "Blow twice, brush twice, blow twice" method?
This traditional method can be used with epoxy and hybrid chemical anchors. However, the process can be time consuming and leave more room for error.
What is the Hilti SafeSet cleaning method?
SafeSet is a proven system that automatically cleans the hole as you drill. This more efficient process requires a Hilti hollow drill bit and an appropriately sized Hilti vacuum cleaner. When used correctly, SafeSet can save you up to 45% of the installation time.
