The fixtures described in Patent Documents 1 to 3 described above are used when the joints provided at the upper and lower ends of the plate material are installed without being cut. However, around the window frame of the building, the handrail wall portion of the balcony, etc., the plate material may not be attached with the specified dimensions, and the joint portion on the lower end surface may be cut. In such a case, since the above-mentioned mounting tool cannot be used, the lower part of the plate material is fixed to the structure by using nails, screws, or the like.

The method of attaching the plate material using fasteners such as nails and screws is relatively problematic because the heads of the nails and screws are inconspicuous because the surface of the handle is finely uneven in the plate material of the handle such as the masonry handle. It is hard to become. However, in recent years, flat and glossy plate materials have been developed, and there is a concern that the method of attaching the plate material to such a plate material by using fasteners such as nails and screws impairs the design of the wall after the plate material is constructed.
