  The leg 2A is formed in a plate shape extending in the horizontal plane along the floor surface FL, and is formed in a horizontally long rectangle in plan view. From the viewpoint of stably placing the legs 2A on the floor surface FL, for example, it is desirable that the legs 2A be made of a metal material such as iron having a high strength and mass. Further, for example, an anti-slip rubber sheet (not shown) may be disposed on the lower surface of the leg 2A.

  The base portion 2B is, for example, a back plate portion 6 extending upward in the vertical plane from the leg portion 2A side, and a front plate portion 7 extending in the vertical plane upward from the leg portion 2A side in front of the back plate portion 6.

  Further, in the holes 18 and 18 of each of the base pieces 3A and 3B, horizontal support shafts 21a and 21b that are orthogonal to the vertical plane, together with the holes 11 and 12 of the back plate portion 6 and the front plate portion 7, Each is inserted. Each of the base pieces 3A and 3B is supported by the base 2B of the main body 2 so that the lower ends of the base pieces 3A and 3B can rotate around a horizontal axis centering on the support shafts 21a and 21b. Thus, since the base pieces 3A and 3B can rotate independently, they are supported by the main body 2 so as to be relatively displaceable.

  The support shafts 21a and 21b of the present embodiment are made of bolts and nuts, and the base pieces 3A and 3B can be easily detached from the base 2B.

  The joint material 3 </ b> C is continuously arranged from the upper end to the lower end of the gap 15.

  A surface finishing material 16 is disposed on the construction surface 3S across a pair of base pieces 3A and 3B. The surface finishing material 16 of the present embodiment is made of at least one horizontally-long rectangular tile, and is disposed on the work surface 3S via the attachment means 17.

  As the attachment means 17, for example, an adhesive, mortar, attachment hardware or the like is used. In addition, for example, a hard adhesive having no elasticity may be used as the adhesive in addition to an elastic adhesive that can absorb the shear deformation of the tile.

  As shown in FIGS. 1 and 2, the displacing means 4 of the present embodiment presses the side surface 3As of one of the pair of base pieces 3A and 3B (the right side base piece in the figure) 3A. It consists of a pressing tool 4A.

  The pressing tool 4A includes a pressing portion 25 that extends vertically along the side surface 3As of one base piece 3A, and a handle portion 26 that is bent at the upper end of the pressing portion 25 and tilts upward. Formed as a lever of the formula. Further, the pressing tool 4A is provided with a hole portion 28 (shown in FIG. 3) penetrating in the horizontal direction between the pressing portion 25 and the handle portion 26. A horizontal support shaft 29 orthogonal to the vertical plane is inserted through the hole portion 28, and is fixed to the back plate portion 6 of the base portion 2B so as to be rotatable about the horizontal axis.

  As shown in FIG. 4, in the pressing tool 4A, when the handle portion 26 is pushed downward, the pressing portion 25 rotates (clockwise in the present embodiment), and the side surface 3As of one base piece 3A. Is pressed.

  By the pressing of the pressing tool 4A, the one base piece 3A is rotationally displaced (counterclockwise in the present embodiment) about the support shaft 21a. Further, the other base piece (left base piece in the figure) 3B is pressed through the joint material 3C by the rotational displacement of the one base piece 3A, and rotates around the support shaft 21b (in this embodiment). , Counterclockwise). These base pieces 3A and 3B can be rotated at different angles due to the difference in the positions of the support shafts 21a and 21b. As a result, the pair of base pieces 3 </ b> A and 3 </ b> B are relatively displaced, and the surface finishing material 16 is subjected to shear deformation.

  When the position of the handle portion 26 of the pressing tool 4A is returned to the original position, the pair of base pieces 3A and 3B are not displaced relative to each other by the restoring force of the joint material 3C, and the shear deformation of the surface finishing material 16 is released. .

As described above, the apparatus 1 according to the present embodiment applies the surface finishing material 16 across the pair of base pieces 3A and 3B, and the surface finishing material 16 only by relatively displacing the pair of base pieces 3A and 3B. Shear deformation can be applied, and for example, durability during an earthquake can be demonstrated. For this reason, the apparatus 1 can be reduced in size compared with the conventional in-plane shear test apparatus, and can be carried and demonstrated anywhere. Moreover, in the apparatus 1, since it is not necessary to construct a big wall, the time and expense which implementation requires can be suppressed. Therefore, the apparatus 1 can easily reproduce the shear deformation of the surface finish 16.

  Moreover, since each base piece 3A, 3B of the present embodiment is removably supported by the main body 2 by the support shafts 21a, 21b made of bolts and nuts, a plurality of surface finishing materials 16 are applied. It is possible to perform a demonstration by replacing with the base plate portion 3 of FIG.

  The support shafts 21a and 21b are preferably provided on the pressing tool 4A side in the base pieces 3A and 3B. Thereby, since the distance between the support shafts 21a and 21b and the pressing portion 25 of the pressing tool 4A is reduced, the turning radius of each of the base pieces 3A and 3B can be reduced, and the pressing amount of the handle portion 26 of the pressing tool 4A can be reduced. The amount of relative displacement of the base pieces 3A and 3B can be increased.

  In addition, if the relative displacement of each of the base pieces 3A and 3B becomes excessively large, distortion generated in the joint material 3C becomes excessive, and the joint material 3C may be peeled off or broken. For this reason, it is desirable that the main body 2 is provided with a stopper 31 that suppresses excessive relative displacement of the base pieces 3A and 3B.

  The stopper 31 of the present embodiment is composed of a rod-shaped body 31A that protrudes from the back plate 6 of the main body 2 toward the front plate 7 on the opposite side of the pressing plate 4A in the horizontal direction with respect to the base plate 3. Such a stopper 31 can be in contact with the side surface 3Bs of the other base piece 3B to suppress excessive relative displacement.

  In order to prevent excessive out-of-plane deformation of the base plate portion 3, it is desirable that the main body portion 2 is provided with a guard member 32. As shown in FIGS. 1 and 2, the guard member 32 according to the present embodiment includes a protrusion 32 a that protrudes from the back plate 6 of the main body 2 toward the front plate 7, and a right angle from the protrusion 32 a. The cover portion 32b that covers a part of the base plate portion 3 is formed in a substantially L shape. In such a guard member 32, the cover portion 32 b abuts on the construction surface 3 </ b> S of the base plate portion 3, and excessive out-of-plane deformation can be suppressed.

  In order to effectively prevent out-of-plane deformation of the base plate portion 3, the guard member 32 includes a first guard member 32A that covers one base piece 3A and a second guard member 32B that covers the other base piece 3B. It is desirable to include. Since the first guard member 32A and the second guard member 32B can abut against the one base piece 3A and the other base piece 3B independently, the out-of-plane deformation of the base plate portion 3 can be reliably prevented.

  Further, the first guard member 32A of the present embodiment is provided on the pressing tool 4A side of one base piece 3A. Further, the second guard member 32B is provided above the other base piece 3B. Since the first guard member 32A and the second guard member 32B are not provided on the stopper 31 side where the base plate portion 3 is displaced, the first guard member 32A and the second guard member 32B are not subjected to out-of-plane deformation without inhibiting the relative displacement of the base pieces 3A and 3B. It can be effectively suppressed.

  Further, as shown in an enlarged view in FIG. 5, it is desirable that the back plate portion 6 of the main body portion 2 is provided with a scale 33 indicating the magnitude of the relative displacement amount of each of the base pieces 3A and 3B. Such a scale 33 is useful for grasping the relative displacement amount of the base pieces 3A and 3B, and can quantitatively evaluate the durability of the surface finish.

  The scale 33 is attached according to a reference scale 33a that represents the position of the upper end of the side surface 3As of the one base piece 3A before the relative displacement of the base pieces 3A and 3B and the relative displacement amount of the base pieces 3A and 3B. Displacement scales 33b and 33c.

  In addition, in the displacement scale 33b, for example, displays 34b and 34c of past earthquake names and the like corresponding to the relative displacement amounts (interlayer displacement angles of the buildings) of the ground pieces 3A and 3B may be described. Such display 34a, 34b can make a general customer etc. understand the surface finishing material at the time of an earthquake concretely and easily.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect. For example, although the base pieces 3A and 3B of the present embodiment are shown extending along a vertical plane, they may extend along a horizontal plane. In such an apparatus 1, since the base pieces 3A and 3B are arranged in parallel with the floor surface, the base pieces 3A and 3B can be stably displaced relatively.

  In the present embodiment, the surface finishing material 16 is exemplified by tiles. However, it is needless to say that the surface finishing material 16 may be a coating film or the like coated on the surface 3S to be constructed.
