PTSPIT FIX Z XTREM, the XTREM segmented fixation (seismic certified heavy duty)
According to the new EN 1992-4, the fastening must be dimensioned as being subject to being inserted in an area of cracks!
Commonly known as MTA, threaded stud or segmented bushing, segmented anchorage has evolved into a reliable anchor with all common certifications in the seismic range. So, we can currently divide this segment into 2 classes.
The first class, made up of the most common anchors known to most people. Bushings, certified or not, made up of steels of different grades, cones with very aggressive angles, an anchoring ring with little thickness and mobility.
The second class, consisting of certified seismic anchors, composed of steels above class 8, less aggressive cone angles, anchoring rings with large thicknesses, composed of special grooves. Indispensable characteristics to resist C1/C2 efforts, option 1 for crack zones, and for good fire performance.
According to the new EN 1992-4, the fastening must be dimensioned as being subject to being inserted in an area of cracks until proven otherwise. Thus, the use of segmented bushings such as FIX Z XTREM seems to be increasingly the way forward. Until last year, this range was used almost exclusively on jobs with tighter design recommendations. This trend has changed due to concerns about the introduction of seismic rehabilitation of buildings. Ensuring C1/C2 connections, associated with fire resistance, gives greater assurance to the engineer, designer and installer.
