FIELD: construction. ^ SUBSTANCE: device for testing a lining coating bonding strength of a building construction by means of detachment of the lining coating has a base with two supports equidistant from the longitudinal axis and arranged in an axial longitudinal plane, and a hydraulic press with a closed hydraulic system. The hydraulic press consists of a piston pump with a manual drive and an actuating cylinder linked with a pull-bar capable of a hinged connection with a grabbing pivot equipped with a steel plate in order to stick to the lining coating. There is also a mechanism of the pull-bar pretensioning and a device for tack force measurement of the lining coating. The base has a central hole for the pull-bar installed inside and capable of a lengthwise movement and the piston pump, the actuating cylinder, the mechanism of the pull-bar pretensioning and the device for tack force measurement are arranged in alignment of the central hole in the base, and the pump piston is installed in the piston of the actuating cylinder. ^ EFFECT: reduced materials consumption and improved transportability; reliability and accuracy of the findings of the device testing. ^ 10 cl, 7 dwg
