PROBLEM TO BE SOLVED: To provide a hammering device 1 for performing a hammering inspection on a concrete wall or the like 61 by moving a ferromagnetic body 12 inserted into a solenoid coil 14 and by controlling the electricity flowing through the solenoid coil 14 so as to move the ferromagnetic body 12.SOLUTION: The hammering device 1 is characterized in that the ferromagnetic body 12 is supported at a position of a central axis 16 of the solenoid coil 14 by an elastic body 18. Since the ferromagnetic body 12 does not contact an inner wall of the solenoid coil 14 by the elastic body 18, no sliding sound is generated as compared with the case where the ferromagnetic body 12 slides in contact with the inner wall of the solenoid coil 14. In addition, the impact when the ferromagnetic body 12 hits the concrete wall or the like does not generate an impact sound that transmits directly to the inner wall of the solenoid coil 14.SELECTED DRAWING: Figure 1

    【課題】ソレノイドコイル14に強磁性体12を挿入し、ソレノイドコイル14に流す電気を制御することで強磁性体12を可動させてコンクリート壁等61を打音点検する打音装置1に関する。【解決手段】弾性体18によって、強磁性体12が、ソレノイドコイル14の中心軸16位置に支持されていることを特徴とする打音装置1を提供する。弾性体18により強磁性体12がソレノイドコイル14の内壁に接触しないので、強磁性体12がソレノイドコイル14の内壁に接触して摺動する場合にくらべて摺動音は発生しない。また、強磁性体12がコンクリート壁等を叩いた衝撃をソレノイドコイル14の内壁に直接伝達する衝撃音を発生しない。【選択図】 図1
