Invention herewith described refers to the floor levelling device on rubber absorbers for residential and business premises consisting of an aluminium frame (1) (which can be disassembled), four jack screws (2), located at the corners of the frame (1), two lasers (3) on each side of the frame (1) and 32 vertically mounted strain gauges (4) with metal girders.The device is placed on the concrete slab (5), by twisting the jack screws (2) the horizontal position is achieved by matching beam of light from the laser (3) with a set and marked on the wall, line (6). The vertical gauges with metal girders with their mass independently abut on the concrete slab (5) and by reading the values on the strain gauges we get the values of deviation that should be compensated by rubber washers on the rubber absorber.
