- Concrete
For anchoring: • Lifting rails • Conveyors or crane systems • Robots • Slewing cranes • Heavy machinery • Fans • Noise control barriers • etc. in cracked and non-cracked standard concrete with strength classes C20/25 and C50/60.
For use in dry indoor areas The VMZ dynamic injection system is a bonded expansion anchor for dynamic loads, consisting of a VMZ composite mortar and a special anchor rod with nut and washer. Using an application gun, both components of the VMZ composite mortar are injected into the drill hole via a mixer nozzle and the anchor rods are inserted manually. The load is transferred via the mechanical interlocking of individual anchor rod cones in the mortar and also via a combination of retention and frictional forces in the concrete.
Advantages
- Approved for general construction for static, predominantly static and dynamic loads in cracked and uncracked normal weight concrete with strength classes C20/25 and C50/60
- High load capacities for safe option
- Maximum dynamic load-bearing capacity when separating static and non-static loads and when taking actual vibration frequency into account
- Usual processing with conventional VMZ chemical injection mortar (may only be processed with this system in accordance with the approval) and quick setting thanks to through-setting installation
- Instant installation checks possible if excess mortar escapes
- Version for pre-positioned installation or combination version deliverable on request
- A4 and HCR version deliverable on request
