Is. The wall panel P is mounted on the wall mounting portion (not shown) of the waterproof floor pan of the bathroom unit to form a bathroom wall.

Film-laminated steel sheet with joint pattern 1
As shown in FIG. 2, for example, a black first film 11 made of vinyl chloride and a white second film 12 also made of vinyl chloride were attached by heating and welding. Two-layer resin film 10
Is, for example, hot-dip galvanized steel sheet (hereinafter referred to as steel sheet 20)
As shown in FIG. 1, a strip-shaped concave portion 1a is formed on the surface (on the side of the resin film 10) of the laminated film-laminated steel sheet so that the side of the second film 12 is in contact with each other. A large number of tiles (in the form of tile joints). In this case, the recess 1
“A” is formed by removing the surface of the resin film 10 by grinding or the like.

Here, the film-laminated steel sheet 1 with joint patterns is, for example, the first and second films 11,
The thicknesses t1 and t2 of 12 are 25 μm and 80 μm, respectively.
m, and the thickness t3 of the steel plate 20 is 1 mm (1000 μm
), It has a total thickness of 1105 μm. Also, this film-laminated steel plate with joint pattern 1
As shown in FIG. 2, for example, the recess 1a has a width W of 2 mm and a depth D of 60 μm reaching the second film 12.
Is formed in. Therefore, the bottom of the recess 1a has the material color (white) of the second film 12, and the surface of the black film-laminated steel sheet 1 showing the material color of the first film 11 has a white color due to the recess 1a. A concave band is formed. Therefore, the decorative plate 2 (wall panel P) formed from the film-laminated steel plate 1 with this joint pattern
The surface has a shape similar to that of a tile wall in which black tiles are attached with white joints.

Next, a method of manufacturing the film-laminated steel sheet 1 with the joint pattern will be described with reference to FIGS. 3 and 4. First, a grinding device for forming the recess 1a will be described. As shown in FIG. 4, this grinding apparatus has a stationary platen 4 capable of fixing a flat thin plate by vacuum suction.
And a cutter part 5 capable of processing a groove with a predetermined width and a predetermined width.
And an arm (not shown) that can move the cutter unit 5 in the X, Y, and Z directions by NC control and can rotate in the horizontal direction. The cutter unit 5 includes a grinding tool 50 including a disk-shaped cutter 51 made of diamond or the like and a drive source 52 for the cutter 51.
Wheels 53b are rotatably attached to both ends of a horizontal shaft 53a, and are supported on a carriage 53. in this case,
The grinding tool 50 can move up and down with respect to the carriage 53 by a specified amount with high precision, and the cutter 5
The width of the outer peripheral portion 51a of No. 1 is formed to be the same as the width dimension W of the recess 1a.

Next, the procedure for producing the film-laminated steel sheet 1 with a joint pattern using this grinding apparatus will be described. First, a cut plate K suitable for the size of the decorative plate 2 is cut out from the film-laminated steel plate wound in a roll shape, and the cut plate K is fixed on the steel plate 20 side as shown in FIG. Vacuum adsorb on 4. Next, the arm is moved back and forth and left and right to position the cutter 51 of the cutter unit 5 above the formation start position of the recess 1a of the cutting plate K, and then the arm is lowered to move the carriage 53 of the cutter unit 5.
The wheels 53b are pressed against the resin film 10 of the cut plate K with a predetermined pressing force to position the cutter portion 5 in the vertical direction.

Next, while rotating the cutter 51, the cutting tool 50 is so arranged that the lower end of the cutter 51 projects downward from the lower end of the wheel 53b of the carriage 53 by the depth D of the recess 1a.
After lowering, the arm is horizontally moved in the direction of the arrow shown in FIGS. 3 and 4, so that the band-shaped recess 1a is formed on the cutting plate K. Subsequently, the arm is moved to move the recess 1a.
After forming the required number of parallel concave portions 1a, the arm is rotated 90 degrees to form a plurality of concave portions 1a orthogonal to the concave portions 1a, thereby forming the film-laminated steel sheet 1 having a predetermined shape from the cut plate K. It

Next, the operation and effect of this film-laminated steel sheet 1 with joint pattern will be described. In this film-laminated steel sheet 1 with joint pattern, since the joint-shaped recess 1a is formed on the surface, it is possible to form a shaded portion on the film-laminated steel sheet whose surface tends to be monotonous and to give depth and depth. it can. In this case, the recess 1a
Is formed by grinding the surface of the resin film 10, so that the film-laminated steel sheet 1 with joint patterns does not require an expensive mold as compared with the case where the recess is formed by press working, and is manufactured accordingly. The cost can be reduced, and various joint-shaped recesses 1a can be formed easily and inexpensively. Moreover, in this film-laminated steel sheet 1 with joint patterns, as compared with the case where the concave portion is formed by pressing, the convex portion is not formed on the back side,
The backup material (gypsum board 3) can be easily attached, and even if the end portion is bent to form the decorative plate 2, the convex portion is not formed on the back surface side.
The collapse of a can be small.

Further, in this film-laminated steel sheet 1 with joint pattern, the resin film 10 having a two-layer structure having different material colors is laminated on the steel sheet 20, and the bottom of the recess 1a is 2
Since the recess 1a is formed so as to cover the film of the second layer (second film 12), the color of the bottom of the joint-shaped recess 1a can be easily changed from the color of the surface side of the film-laminated steel sheet 1 with a joint pattern. Thus, the surface side of the film-laminated steel sheet 1 with the joint pattern can be easily formed in the same state as the tile wall.

By the way, by laminating a resin film on which a joint-like pattern is printed on the steel plate 20 or by printing the joint-like pattern on the film-laminated steel sheet by silk screen printing, the joint-like pattern is formed on the surface of the film-laminated steel sheet. However, in this case, since the joint-patterned film-laminated steel sheet does not have a recess, it is not possible to form a deep or deep wall surface. In particular, in the case of a resin film on which a joint-like pattern is printed, a large tensile force is applied to this resin film when laminated on a steel plate, so that the joint-like pattern is distorted (curve if it is a straight line pattern). , A proper joint pattern is not formed sufficiently.

As shown in FIG. 5A, when an opaque one-layer resin film 10 is laminated on a steel plate 20, a joint-like recess is formed on the surface of the resin film 10 by grinding. The same effect as described above can be obtained also by the film-laminated steel sheet 1 with a joint pattern on which 1a is formed. In this case, the joint-like pattern does not appear clearly, but as shown in FIG.
By applying a paint 13 of a color different from that of the resin film 10 in a so as to form a recess, it is possible to clearly express the joint pattern.

Further, as shown in FIG. 6, the first, second and third films 11, 12 having different colors (material colors),
When the resin film 10 having a three-layer structure in which 14 is heat-welded is laminated on the steel plate 20, the concave portion 1a is
As shown in FIG. 6A, the recesses are formed so as to reach the second film 12 or reach the third film 13 as shown in FIG. 6B. The color of the bottom side of 1a can be variously changed. That is, the film-laminated steel sheet 1 with a joint pattern in which the color of the bottom side of the recess 1a is a desired color (one color)
It becomes possible to rapidly form the above, and it becomes possible to easily form the concave portion 1a having various kinds of colors on the bottom side in one piece of the film-laminated steel sheet 1 with joint pattern.

Further, by replacing the first film 11 of the resin film 10 shown in FIG. 6 (b) with a transparent film (for example, polyethylene lalephthalate (PET) film), the film-laminated steel sheet 1 with a joint pattern is formed. It can give the surface a luster and shine.
