Distance tubes and sealing cones

Distance tubes are used to guarantee concrete wall thickness using reusable tie bars.

The engineered solution for formwork shutter ties:

• High compressive strength
• Large contact area, therefore reduced pressure on the formwork
• Conform to EN1992-1:2004 (concrete and reinforced concrete) and DIN 18216 (formwork ties for concrete formwork)
• Can be manufactured as an impermeable shutter tie system
• Fire resistance rating F30 - F180 and suitable for fire walls (F90) to DIN 4102

For drinking water reservoirs FRANK offers the “TW“ version of the distance tube, with approval for drinking water applications and can be used without any restrictions.

During formwork erection and concreting of walls using reusable tie bars conical recesses in the concrete are formed. FRANK exposed fibre-reinforced concrete sealing cones do not only allow for sealing these recesses, but they are at the same time a modern architectural design feature. 

• Individual design possibilities for concrete surfaces
• Quick and reliable sealing of recess holes
• Smooth surface of low porosity
• Exposed concrete of the highest quality
• Part of an impermeable sealing system for shutter tie holes
  

FRANK offers a new sealing stopper FB-Kombistop made of fibre-reinforced concrete and silicone rubber for sealing of shutter ties. This material combination allows for watertight sealing of distance tubes by simply driving in the sealing stopper using a rubber mallet.

Distance tubes can be sealed quickly and simply at any time without interruption to work on the construction site. As the stopper is immediately effective, the next concrete pour can commence without delay and the stopper can be exposed to hydraulic pressure.
