Fig. 2: Place the first floor slab on the Deltabeam and affix the first DTB to the predetermined point.
Fig. 3: Continue placing floor slabs until the next fixing point is reached, and attach the next DTB.
Fig. 4: Continue until all slabs and DTBs are in place. Remove DTBs only after concrete has hardened in the Deltabeam.
Deltabeam is a hollow beam made of welded steel plates with holes on each side. After precast slabs are installed, the holes are filled with concrete to create a steel-concrete composite beam.
