PURPOSE:To efficiently and simply inspect an exterior wall for floating state in a light-weight state where the labor required for the inspection is reduced by giving a light impact to the external wall, etc., by using a knocking piece and solenoid plunger for driving the knocking piece as main means. CONSTITUTION:A supporting member operating lever 8 is rotatably fitted to a connection bracket 7 installed to a main body section 6 and tension springs 9 are fitted between them. A solenoid plunger 3 is constituted of a cylinder 11 in which a solenoid coil is housed and a plunger 12 which makes reciprocating motions in its axial direction at the center of the cylinder 11 and a knocking piece which transmits impacts is provided at the front end of the plunger 12. The main body section 6 is moved to an inspecting point along the lower surface of an exterior wall F. By making the piece 13 fitted to the plunger 3 to make reciprocating motions, impacts are lightly given to the external wall F. The floating state of the exterior wall can be efficiently inspected through the feeling and sounds, and by the use of a sound collecting microphone and a TV camera. |
