発された。 In order to solve this problem, the conventional method was to tap the mortar or tile surface lightly with a hammer to find the peeling point based on the difference in sound, and then drill an appropriate hole in this area to eliminate any water that has entered. Inject adhesive through this hole when you think it is. A method was developed.

するようにしていた。 The grade of adhesive to be injected must be selected depending on the internal moisture condition. Therefore, it is essential to know the moisture condition of the adhesive injection point. Conventionally, when creating adhesive injection holes, holes were drilled at two equal intervals to serve as electrode insertion holes, and was inserted to detect continuity between two points.

解決する電極装置を提供するにある。[Problems to be solved by the invention] Figures 1a and 1b show conventional electrodes. Two holes 4 of a predetermined depth are provided at intervals d in the concrete body 1 that is thought to have flaked, and the electrode members 10 are inserted so as to be in contact with the gaps 5, and the lead wires 11 have electrical resistance. Connect the meter and check continuity. However, with conventional electrodes, the diameter of the electrode member 10 is selected to be slightly thicker than the hole diameter, which tends to cause poor contact, and the concrete structure also fluctuates due to changes in temperature, which can lead to complex problems. In order to solve this problem, the electrode member is often left inserted, and in some cases, several hundred sets are required. The object of the present invention is to provide an electrode device that solves this problem of poor contact.
［実施例］
図面を参照して本考案電極装置の構成、使用法

ある。 First, two measuring holes 4 as shown in FIG. 1a are provided at equal intervals. An electrode device according to the invention, indicated by reference numeral 8 in FIG. 2, is inserted into the hole 4 as required for the measurement. Of course, one set of electrode devices 8 is provided at two locations.

れている。 When inserting, as shown in Fig. 2a, it is inserted to a predetermined depth. There is a slight gap 12h between the lower surface of the flange portion 12' of the cylinder 12 and the measurement surface. Therefore, when the lever 16 is pushed down as shown in FIG. 2b, the cylinder 12 is pushed down, and the electrode member 10 is expanded and firmly attached to the measurement surface. The piston rod 13 extends to the upper top case 14, and is connected to an electric resistance meter (not shown) via a lead wire 11.
