FIELD: technological processes.
SUBSTANCE: invention relates to the field of construction industry and may be used for high-quality processing of nonsolidified surfaces of reinforced concrete items formed from concrete mixes for civil and industrial construction. Disk smoothing working element with curvilinear horizontal oscillations consists of damping device, body, smoothing disk, driving shaft, at the end of which there is a planetary single-step reducer. Unbalance is provided at driving shaft, which may rotate and makes working element oscillate in horizontal plane along curvilinear trajectory, possibility to transfer rotation of driving shaft makes it possible to transfer rotation torque to planetary single-step reducer, at output shaft there is a smoothing disk fixed via flange joint, and it may rotate and curvilinearly oscillate in horizontal plane, metal flexible elements prevent oscillations in vertical plane.
EFFECT: high quality of items surface processing.
