Each finishing material 1 includes a thin titanium sheet 10 as a metal sheet whose surface 10A is the finishing surface, and a backing board material 12 that is integrally attached to the back surface 10B side of the thin titanium sheet 10 by an adhesive 14. I have.

The thin titanium sheet 10 is excellent in rust resistance and corrosion resistance in addition to chemical resistance, thermal shock resistance and wear resistance, and has high durability. As the thin titanium sheet 10, for example, a sheet having a thickness of about 0.3 mm (0.1 mm to 0.5 mm or the like) can be employed. Further, as shown in FIG. 1, the edge 10X of the thin titanium sheet 10 is bent to the small edge 12X side of the backing board material 12, and the bent edge 10X and the small edge 12X are separated to form a gap 13. ing.

Further, instead of the thin titanium sheet 10, a copper sheet or a thin stainless steel sheet having at least one of rust prevention and corrosion resistance may be adopted.

The backing board material 12 can be a flexible board, a cement-based board, a plastic board, a wooden board, or the like, and has at least a certain strength as a backing material. The thickness of the backing board material 12 can be, for example, about 3 mm to 10 mm. Specifically, a power board (trade name: manufactured by Kuraray Co., Ltd.), a smooth board (trade name: manufactured by Obayashi Corporation), or the like can be employed as the backing board material 12.
As the adhesive 14, a low odor or odorless type urethane resin or epoxy resin-based one can be suitably used, and an adhesive having excellent adhesion to the thin titanium sheet 10 and the backing board material 12 is preferable.

Next, the construction method (finish surface construction method) of the finishing structure 2 will be described.
First, the surface fastener 16 is attached to the position marked on the surface 3A of the concrete floor 3 in advance. Next, as shown in FIG. 1, a planar fastener 17 that is joined to the planar fastener 16 is attached along the outer periphery on the back surface 12 </ b> B side of the backing board material 12 constituting the finishing material 1. Adhesive 18 is provided on the inner part surrounded by. Then, the finishing material 1 and the floor 3 are joined by joining the planar fasteners 16 and 17 and the adhesive force of the adhesive 18. Such an operation is performed over the entire surface 3A of the floor 3, and a plurality of finishing materials 1 are attached at predetermined intervals. At this time, as shown in FIG. 1, joint portions 20 are formed between the adjacent finishing materials 1. A planar fastener 16 attached to the surface 3 </ b> A of the floor 3 is provided at the bottom portion of the joint portion 20.

  Next, the joint material 20 is filled with a joint material 22 as a general sealing material such as urethane resin, silicone-modified epoxy resin, modified silicone resin, or silicone resin, and is cured. At this time, the joint material 22 is entangled with the projection (loop or hook) of the planar fastener 16 of the joint portion 20, and the water resistance and the chemical resistance are excellent. Moreover, the filling of the joint material 22 prevents entry of dust, drainage, or the like into the joint portion 20. In the case where there is a concern about the occurrence of fungi, molds, or the like in the joint portion 20, a joint material 22 containing a silver-based antibacterial agent may be used. Finally, the covering material 24 is disposed across the adjacent finishing materials 1 so as to cover the surface of the joint portion 20, and the covering material 24 is applied to the surface 10 A of the thin titanium sheet 10 and the joint material 22 by the adhesive 26. Adhere and fix. As such a covering material 24, what formed the thin titanium sheet 10 in strip shape etc. is employable, for example. The finishing structure 2 is constructed by the above procedure.

(3) Even if a crack occurs in the concrete floor 3, the crack does not affect the thin titanium sheet 10, so that the surface of the finishing material 1 can be kept clean.

(4) Since the thin titanium sheet 10 and the backing board material 12 are integrally formed in a panel shape, the finishing structure 2 can be easily configured, and the finishing surface can be easily constructed.
(5) By reducing the thickness of the thin titanium sheet 10 of the finishing material 1 to about 0.3 mm, the weight of the finishing material 1 can be reduced, and the finishing surface construction work can be facilitated. Moreover, since the thin titanium sheet 10 can be easily cut using a diamond cutter or the like that is generally used in the field for cutting the cement-based board material, an on-site rapid response is facilitated.

  (6) Since the gap 13 is formed between the edge 10X of the thin titanium sheet 10 and the small edge 12X of the backing board material 12, when the joint material 22 is filled in the joint portion 20, the joint material 22 is also formed in the gap 13. Therefore, when the entering joint material 22 is hardened, a kind of anchor effect is exhibited, and the bonding between the finishing material 1 and the joint material 22 can be further strengthened, and the joint material 22 can be prevented from peeling off.

In addition, this invention is not limited to the said embodiment, Other structures etc. which can achieve the objective of this invention are included, The modification as shown below is also contained in this invention.

At this time, a double-sided tape may be employed instead of the planar fasteners 16 and 17.

  Further, instead of the surface fasteners 16 and 17, fibers such as glass fibers and organic fibers (chopped strand mat, non-woven fabric, woven fabric, etc.) are attached to the back surface of the finishing material with an adhesive, and the adhesive is cured. After that, the finishing material may be joined to the floor. If it does in this way, while being able to improve water resistance and chemical resistance, joining of a finishing material and a floor can be made still stronger.

Then, a method of attaching the finishing material 1 may be employed, or an adhesive may be applied directly without using a primer. Moreover, as a 2nd method, it is the method of constructing using a cement mortar and a polymer cement mortar. For the polymer cement mortar, an emulsion of polymers such as ethylene vinyl acetate, acrylic resin, styrene butadiene rubber (SBR) can be used. In this case, after the diluted aqueous solution of the polymer emulsion is applied and impregnated on the floor surface, it is attached by using cement mortar or the like, thereby further strengthening the bonding between the finishing material and the floor. In this case, cement mortar or the like may be applied without applying a primer to the floor surface.

  In the embodiment, the planar fastener 16 is disposed on the bottom portion of the joint portion 20 and the joint material 22 is filled from above the planar fastener 16. However, the present invention is not limited thereto, and the backer material is provided on the bottom portion of the joint portion 20.

According to such a configuration, the protruding portion 25 </ b> A of the covering material 25 is embedded in the joint material 22, so that the displacement of the covering material 25 can be prevented.
Moreover, in the said embodiment, although the joint material 22 and the thin titanium sheet | seat 10 were joined by the adhesive agent 26, you may join using a double-sided tape, and you may join using a heat-fusion tape. Further, the joint material 22 itself may be used as an adhesive, and in this case, it can be carried out by filling the joint material 22 so much that the surface is raised.

  Further, as shown in FIG. 9, a joint rod 27 may be inserted into the joint material 22. In this case, even when the joint portion 20 has a large width dimension, the presence of the joint rod 27 can reduce the impact during travel of a forklift or the like. Further, the covering material 24 may be provided so as to cover the joint rod 27, and in this case, the covering material 24 can be supported by the joint rod 27. Note that the same modification as described above can be applied to the covering material 24.

You can also. For example, as shown in FIG. 10, a finishing material 1A is attached to the surface 3A of the floor 3 with an adhesive, and a finishing material 1B is attached to the surface 100A of the wall 100 with an adhesive, and between these finishing materials 1A and 1B. By filling the joint material 22, the corner 102 can be constructed. In addition, as a finishing material, the modification similar to the above-mentioned can be applied.

Further, as shown in FIG. 11 (A), a notch 104 is made in the substantially central portion of the backing board material 12 of the finishing material 1C, and as shown in FIG. It may be bent at an angle and joined to the corner 102 with an adhesive 106. In addition, a side groove can also be constructed using the finishing material 1 in the same manner as the corner 102.
