Description

The present invention relates to an inspection tool for a structure, and is used for inspection from the surface side particularly for the presence or absence of peeling, deterioration, expansion, foreign matter contamination, etc. in mortar, tile, concrete, etc. forming the wall part of the structure. Regarding equipment.

If peeling, deterioration, expansion, foreign matter contamination, etc. occurs on the mortar sprayed on the walls or ceiling of the structure, the tiles pasted on it, etc., the part where the peeling etc. is occurring will fall and cause an accident. , Regular inspections are carried out. A general inspection method is a method in which an inspection worker hits the surface with an inspection hammer and determines the presence or absence of peeling or the like of mortar or the like based on the echo sound, and this method is called a percussion method.

In response to the above percussion method, the applicant has previously proposed an inspection tool for a structure or the like (Patent Document 1). This inspection tool is equipped with a tumbler that is rotatably supported by the tip support shaft of the operation paddle, and the operator holds the operation paddle in his hand and holds the tumbler (the tumbling surface) on the surface of the structure or the like. In this state, if the operation paddle is shaken or moved along the surface of the inspection point, a loud striking sound is generated when the tumbler rolls, and peeling or the like occurs like the inspection hammer. It is possible to distinguish between a healthy part and a healthy part.
