Concrete/asphalt device for producing a level surface layer of dumped hardening building material like concrete/asphalt has a draw-off crosspiece with computer-controlled height levels |
摘要 |
A draw-off crosspiece (4) stretches crosswise to a direction (F) of progressive motion and evenly draws off building material (3) like concrete/asphalt with a draw-off rail (5) according to a level reference surface plane prepared by a measuring device (12). The draw-off crosspiece links to a support device (7) on the side ends. An adjuster assigned to each draw-off rail can be adjusted as to its height. Near the support device, a receiver is aligned to a beam of light from the measuring device transmitter to make an effective computer-controlled link to an adjuster that keeps the draw-off crosspiece height level constant. -
