A device for penetration of building elements has a U-like frame (1) with loading masses (3), pressure hydro-cylinder (5), vibration exciter (7) of electromagnetic type installed between the hydro-cylinder (5) and the embedded element (2). New is the fact that the vibration exciter (7) is equipped with a two-chamber, with different volumes, vessel (30) with liquid (31), each of the chambers (32, 33) has at least one movable wall (34, 35), the movable wall (34) of the chamber (32) with smaller volume interacts with the movable magnetic system (9) of the vibration exciter (7), and the movable wall (35) of the chamber (33) with larger volume – with the embedded element (2), at that the area of the movable wall (34) of the chamber (32) with smaller volume is smaller than the area of the movable wall (35) of the chamber (33) with larger volume. The invention provides increase of vibratory component of penetration force. |
