FIELD: construction.
SUBSTANCE: invention is related to the field of construction industry and may be used for high quality processing of nonsolidified concrete surfaces from rigid concrete mixtures used for civil and industrial construction, and also in installation of road asphalt concrete carpets. Vibration tape working element in the form of eccentric drive mechanism comprises body with vibration working element, which is installed directly on internal surface of tape and is able to transfer vibration effect to tape by means of four vibration plates, which are separated into two groups that vibrate in antiphase by means of eccentric shaft rotation, which may change frequency and amplitude of oscillations in process of operation.
EFFECT: reduced wear of tape, lower vibration transferred to portal of smoothening machine, higher quality of concrete mix smoothening.
