Filling of the cavity below a horizontal plate provided with anchoring elements with >=2 layers of a material in such a way that the layer directly below the plate is compressed last, by placing a filling tube over at least a part of>=2 openings in each compartment delimited laterally by ribs in the concrete plate which is reinforced in its lower part, whereby the lower edge of the filling tube does not reach the lower edge of the ribs, vibrating the material after this has been introduced through the filling tubes so as to extend to the lower edge thereof, removing the tubes and then introducing the material through >=1 opening in each compartment, and finally closing off all the openings except one per compartment, and continuing to direct a flow of material into each compartment through such opening until the moment it hardens, then closing off the opening. |
