A part is selected as a measurement target region, and the adhesive strength thereof is measured by following the measurement procedure described below. This will be described with reference to FIGS. 3 (A) to 3 (C). Concrete 3 is formed around a measurement target region 38 having a square area surrounded by sides AB to DA of the coating floor 32 whose adhesive strength is to be measured.
A groove 33 reaching the surface of No. 1 is formed so as to be isolated from the surrounding coating floor 32. Furthermore, a steel attachment jig 35 having a cubic rigidity and having the same area as that of the measurement target area 38 is fixed by an epoxy resin adhesive 34, and the jig 35 fixes the measurement target area 38 of the coating floor 32. Completely restrain the entire surface. Next, the nut 37, to which a tensile force is applied, is fixed to the central portion of the upper surface of the jig 35, that is, on the extension line of the central portion of the measurement target region 38 by the welding portion 36. Then, the pulling force F is applied upward to the nut 37.
Interface 3 between the concrete 31 and the painted floor 32
A tensile force is exerted on the whole 9 and the adhesive strength of the coated floor is measured from the ratio of the tensile force at the time of peeling and the measurement target area 38, that is, the effective adhesive area.

装置１を構成する。The side members 8B and 8C having the same area as the measurement target region 6 are extended from both ends of the connecting member 8A in a direction orthogonal to the connecting member 8A to have a substantially horizontal U-shape, and as will be described later, A side member 8B of the attachment 8 formed of a rubber-based member having a deformability such that an eccentric load can be applied to the edge of the effective adhesion region 12 is applied to the side member 8B of the measurement target region 6 by applying a tensile force. The connecting member 8A is positioned at the end and adhered to the entire surface thereof, thereby restraining the measurement target region 6. Further, a hook-shaped spatula or the like inserted from the groove 4 side in the horizontal direction of the interface 13 between the coating floor 3 and the concrete 2 on one side of the measurement target region 6 on the side where the connection member 8A of the attachment 8 is located. The surface of the concrete 2 in the groove 4 is cut with a tool to a predetermined depth, and then the concrete 2 is cut along the interface 13.
When only the two are carefully carved, a gap 5 is formed between the measurement target region 6 and the concrete 2, and the edges of both 2 and part of 6 are cut, as shown in FIG. Side DA
Side A indicated by a dotted line that is smaller than the measurement target area 6 surrounded by
An effective adhesion area 12 surrounded by E to side DA is formed. Then, on the surface of the other side member 8C of the horizontal U-shaped attachment 8 and at the center point r of the effective bonding region 12.
An adhesive force measuring device 1 is configured by fixing a bolt-shaped pulling member 11 to which a pulling force is applied on the extension line of 1 with nuts 9 and 10.

辺幅ＥＦの長さとの比から接着強度を求める。According to this structure, when a gradually increasing pulling force F is applied to the pulling member 11, the pulling force F is transmitted to the side member 8C of the attachment 8 and then to the side member 8B while deforming the connecting member 8A. , Is transmitted to the measurement target region 6. However, since the gap 5 is formed on the side where the connecting member 8A is provided and the attachment 8 is deformable, the sides of the attachment 8 follow the upward displacement of the coating floor 3 on the gap 5. When a part of the member 8B is deformed upward, and an unbalanced load is applied to the side EF of the effective bonding area 12 adjacent to the gap 5 and the pulling force becomes larger than the bonding force, the concrete 2 is peeled off. Instead, the coating floor 3 is peeled off in a situation close to the peeling test. Then, the adhesive strength is obtained from the ratio of the tensile force at the time of peeling and the length of the side width EF of the effective adhesive area 12.
