The truss contains at least one reinforcement rod (13) intended to be cast in when inside the chord and at least two reinforcement rods (14;14') intended to be cast in when inside the slab. The arrangement contains a base beam (1) with sheet metal holders (2) fastened to and standing perpendicularly above the beam (1) at a certain regular distance from each other, and with guiding devices (3;21) of pyramid or prism shape with rectangular base and its top facing upwards, in principal centrally placed at same regular distance from each other, fastened standing above the base beam (1).
