As shown in FIGS. 4 and 5, the main body 2 includes a panel support portion 20 surrounded by four sides, and a first side portion 21 and a second side portion that are continuous with the two opposing sides of the panel support portion 20. 22 , and a third side portion 23 and a fourth side portion 24 that are continuous with two opposite sides of the panel support portion 20 . That is, the four side portions 21 , 22 , 23 and 24 are provided around the panel support portion 20 .
The four sides of the panel support portion 20 have the same length, and the surface shape of the panel support portion 20 is square. The first, second, third and fourth side portions 21 , 22 , 23 and 24 protrude from the rear surface of the panel support portion 20 .

The surface panel 3 is supported by the surface 20 a of the panel support portion 20 . That is, the surface 20 a of the panel support portion 20 is the surface of the main body 2 . The surface 20a is a flat surface, and the panel supporting surface of the panel supporting portion 20 is a flat surface. The panel support portion 20 has a plurality of holes 25 extending through the front surface 20a and the rear surface 20b.
The four side portions 21, 22, 23, and 24 are perpendicular to the front surface 20a of the panel support portion 20 toward the rear surface 20b side, and the tip surfaces 21a, 22a, 23a, and 24a are located on the rear side of the rear surface 20b of the panel support portion 20. positioned. That is, the sides of the panel support portion 20 and the outer surfaces of the four side portions 21, 22, 23, and 24 are the side surfaces of the main body 2, and the back surface 20b of the panel support portion 20, the four side portions 21, 22, 23, The tip surfaces 21 a , 22 a , 23 a , 24 a of 24 and the inner surface are the back surface of the main body 2 . The four side portions 21 , 22 , 23 , 24 are continuous to form a mounting frame 26 around the panel support portion 20 .
The four sides 21 , 22 , 23 , 24 have the same number of projections 27 , cutouts 28 for projections, and cutouts 29 for front panel fixing.

The protrusions 27 protrude laterally from the tip surfaces 21a, 22a, 23a, and 24a of the four sides 21, 22, 23, and 24 at right angles to the sides. It is triangular in shape, wider than the sides. That is, the projecting portion 27 protrudes laterally from the side surface of the main body 2 .
The rear surface 27a of the protrusion 27 is the installation surface, and the rear surface 27a is positioned behind the tip surfaces 21a, 22a, 23a, and 24a of the four side portions 21, 22, 23, and 24. As shown in FIG.
The projecting portion 27 has a fixing hole 27b.
The cutouts 28 for protrusions are opened at the end surfaces 21a, 22a, 23a, and 24a of the sides 21, 22, 23, and 24, and have a width wider than the width of the sides of the protrusion 27. It is deeper than the plate thickness of 27. In other words, the projection cutout 28 has a shape and size that allow the projection 27 to be inserted thereinto.

As shown in FIG. 6 , the front panel fixing notch 29 is formed by cutting the bottom surface of the projection notch 28 on the fourth side 24 with a width narrower than that of the projection notch 28 . It is lacking and formed. In other words, the cutout portion 28 for projection and the cutout portion 29 for fixing the surface panel are continuous in the shape of a chevron.
Therefore, by processing one cutout portion, it is possible to form the projection cutout portion 28 and the surface panel fixing cutout portion 29, so that the cutout portions can be easily processed.
Note that the notch 28 for projection and the notch 29 for fixing front panel may be formed at different positions.

The projections 27 formed on the four sides 21, 22, 23, and 24 and the cutouts 28 for the projections are positioned at the same distance from one longitudinal end of the four sides 21, 22, 23, and 24. are formed respectively. In other words, when the two main bodies 2 are arranged side by side, the projection 27 and projection notch 28 of one of the main bodies 2 are fitted with the projection notch 28 and projection 27 of the other main body 2, respectively. It is like this.
For example, as shown in FIG. 7, two main bodies 2 are arranged side by side on a panel installation portion (not shown), and the right third side portion 23 of the left main body 2A and the left fourth side portion of the right main body 2B are arranged. 24, the protrusion 27 and the protrusion cutout 28 on the right side 23 of the left main body 2A and the protrusion 24 on the left fourth side 24 of the right main body 2B. The notch 28 and the projection 27 are fitted together. That is, the protrusion 27 and the notch 28 for the protrusion are arranged circularly symmetrically. This is the same when the metal panel 1 is formed by attaching the surface panel 3 to the main body 2 .

Since the protrusion 27 has a triangular shape, the main body 2 to be installed is obliquely moved with respect to the main body 2 already installed, and the protrusion 27 is cut for the protrusion of the main body 2 already installed. When inserting into the notch 28, the protrusions 27 do not interfere with each other. Moving the main body 2 obliquely means not moving (translating) in a direction perpendicular to the four sides 21 , 22 , 23 , 24 , but moving in a direction perpendicular to the four sides 21 , 22 , 23 , 24 . It is to move in the direction of a small angle, say 45 degrees.
Therefore, as shown in FIG. 7, one main body 2D to be installed is directed in the direction of the arrow (main body 2C ), the projections 27 of the body 2D to be installed do not interfere with the projections 27 of the bodies 2C and 2B that have already been installed. A third side portion 23, a projection portion 27 of the first side portion 21, a cutout portion 28 for the projection portion, and two side portions 24 of the one main body 2D to be installed. , 22 can be fitted with each other. This is the same when installing the metal panel 1 .

The main body 2 is formed by punching, drilling, bending, etc. a metal plate having a large thickness using a die and a press machine, and forming four side portions 21, It is shaped to have bent pieces 22, 23, and 24. As shown in FIG. As the metal plate, a stainless steel plate having a thickness of 1 mm is preferable, but the metal plate is not limited to this.
The diameter of the hole 25 of the panel support portion 20 is set to 5 mm to 6 mm, which is five times or more the thickness of the plate, so that the mold is less likely to deteriorate.
The hole 25 is not limited to a circular shape, and may be oval or rectangular. Moreover, it is possible to form a shape in which the peripheral portion of the hole 25 protrudes slightly from the rear surface 20b of the panel support portion 20 by cutting and bending. This makes it difficult for the adhesive, which will be described later, to leak from the holes 25 .
The body 2 can also be manufactured by casting.

As shown in FIGS. 2 and 3, the claw portion 31 of the surface panel 3 is bent so as to involve the bottom portion of the panel fixing notch portion 29 in the side portions 21, 22, 23, and 24 of the main body 2, A surface panel 3 is fixed to the main body 2. - 特許庁The bent portion of the claw portion 31 is accommodated in the panel fixing notch portion 29, and the bent portion can protrude from the end surfaces 21a, 22a, 23a, and 24a of the side portions 21, 22, 23, and 24 of the main body 2. do not have. Note that the claw portion 31 may be bent so as to involve the leading end surfaces of the side portions 21, 22, 23, and 24 without providing the panel fixing notch portion.
As shown in FIG. 9, the claw portion 31 can be easily bent by making a hole 31b near the tip of the claw portion 31 and inserting a tool into the hole 31b to bend the claw portion 31. As shown in FIG. Forming a hole 31b in the bent portion of the claw portion 31 also facilitates bending.
Moreover, the hole 31b of the claw portion 31 can be used as a hanging hole for hanging the surface panel 3 during painting work.

By combining the surface panel 3 and the main body 2 as described above, the following advantages are obtained.
Since the main body 2 and the surface panel 3 are fixed with an adhesive and a claw part 31, the surface panel 3 does not come off from the main body 2 when the metal panel 1 is transported or installed.
The bottom surface 34a (main body contact portion 4) of the concave portion 34 of the decoration portion 3a of the surface panel 3 (main body contact portion 4) and the surface 20a of the panel support portion 20 are in contact with each other, and the contact portion is bonded with an adhesive. The part 3a is reinforced by the main body 2, and the decorative part 3a, which is thin and weak in strength, is hardly deformed and can maintain its strength. When the decorative portion 3a is struck, the bottom surface 34a (main body contact portion 4) of the concave portion 34 does not collide with the surface 20a of the panel support portion 20 and noise is not generated.

The air permeability in the space 5 is excellent due to the holes 25 of the panel support 20, and the adhesive applied to the surface 20a of the panel support 20 for joining the contact parts of the main body 2 and the surface panel 3 is used. Curing is accelerated and the adhesive cures early, so that the metal panel 1 can be manufactured in a short time, improving production efficiency. Moreover, it is preferable to provide the holes 25 so that at least one hole 25 always exists in one space portion 5 . According to this, it is possible to improve the air permeability of the space portion 5 and accelerate the hardening of the adhesive.
