Abstract (en)

A device 1 for screeding a region of freshly laid concrete 25 comprises a beam 2, a leading blade 3, and a trailing blade 4. The beam 2 is hollow and defines an interior housing space 10 within the beam 2. Three air-operated vibrators 11 are provided located in the beam interior housing space 10, and spaced-apart along the beam 2. A plurality of corresponding access openings 13 to the beam interior 10 are provided in the trailing side of the beam 2 for gaining access to any of the vibrators 11 within the beam interior 10. The device 1 is used to screed a region of concrete 25 by vibrating the beam 2 as the beam 2 is moved over the region of concrete 25 with the blades 3, 4 in contact with the concrete 25. A winching arrangement may be used to draw the beam 2 over the region of concrete 25. <IMAGE>
