(57) The present invention relates to the field involved in the construction of roads, surfaces for HGV traffic, machines or accessories for construction or repair, specifically of road surfaces, arrangement or structure of junctions. The invention consists of a sinusoidal preformed expansion joint for industrial floor slabs; formed by undulating plates supported on a sheet that also has an undulating shape along the same sinusoidal path as the plates, maintaining the same vertically continuous sinusoidal wave pattern as the plates, forming a single smooth structure, without sub-divisions or perpendicular sections and with splice joints with side overlapping, continuous with the sinusoidal line of the joints assembled with male/female-type smooth dowels without the need for welds; undulating over the entire width of the cast slab which, owing to its shape, provides greater strength without critical areas of shear stress, whether from static or dynamic loading.
