DEMA CLASSIC TUNNEL FORM SYSTEM (DCS)

The Dema Advanced Tunnel Form System (DATFS) is an improvement on perfect, allowing concrete to be poured upto 1.5 hours earlier each day! Due to the quick release diagonal adjusting prop the DATFS does not need manual adjustment at every usage; additionally the quick set and release system means that the formwork can be struck from the concrete surface with two easy movements, releasing the prop and lowering the jacks. The 3rd cross beam at the top of the vertical panels is vital with any diagonal prop load bearing system as it provides the necessary rigidity to the stress bearing joint of the horizontal and vertical panels ensuring the formwork does not distort and warp over time and therefore creating either a ‘lip’ on the concrete surface or needing repair/replacement.

To remove the system there is a wide clog free roller manufactured with sealed bearings to ensure a smooth movement. In fact the formwork can be moved with just a single hand. The rollers also minimize any damage to the floors when removing the formwork. Finally there are compartments for tools and to assist the tunnel form workers in moving the formwork accessories to the next floor/pour location. Due to the additional speed in placement and removal the formwork allows a slightly larger floorplan to be completed daily and is preferred for the 350-500m2+ a day layouts.
