TECHNOLOGY WITH THE POWER TO TRANSFORM

The core of the N3P system – the innovative butterfly technology – is found inside the portable precast plant. The high-performance battery is equipped with removable, folding and double-sided steel butterfly formworks. A butterfly formwork comprises two formwork panels that are held together by a hinged joint.

The N3P has been designed with top performance and maximum productivity in mind. Our solution combines the advantages of preparing the elements in a flat position and pouring the concrete into vertical formworks.

Step 1 PREPARATION

  • Tie in the reinforcing cages on the rebar gauge tables

 
Step 2 POSITIONING
Img

  • Assemble stop-end and box-out formworks
  • Position ready-made rebar cages on the butterfly
  • Assemble inlays for electrical cables and plumbing

 
Step 3 POURING

  • Lift the prepared butterfly into the pouring chamber of the duplex battery with the crane
  • Repeat lifting process until pouring chamber contains 7 butterflies
  • Close the pouring chamber by pushing the end shutter wall towards the centre of the pouring chamber
  • Mount form ties to secure position
  • Pour the concrete in layers, using a concrete pump and rotary distributer

Step 4 INITIAL CURING

  • After approx. 4 hours of curing, the precast elements are lifted out and positioned together with the butterfly at the initial curing area

 
Step 5 OPEN FORMWORKS
Img

  • Precast elements rest for another 4 hours
  • Strip box-outs and stop-end formworks
  • Separate panel from butterflies using a crane

 
Step 6 FINAL CURING

  • Transport the panels to the final curing yard
  • Allow the panels to cure until the required strength for shell assembly is achieved
  • Transport from the curing yard to the desired location for assembly

Based on an exclusive NEULANDT GmbH licence, BT Innovation distributes the patented butterfly formwork and battery only for stationary applications.
