Description

  The present invention relates to a metal siding panel and a method of manufacturing the same.

  Conventionally, as a siding panel used for an outer wall of a building or the like, a metal siding panel is known in which a plurality of metal plates are formed in a concavo-convex shape, and a plurality of adjacent pieces are fitted to each other. The metal siding panel passes a metal plate between a pair of embossing rolls at the time of shaping | molding, and forms uneven | corrugated shape. Under the present circumstances, in order to prevent that a twist, a wrinkle, etc. are formed in a metal plate, it emboss also in the fitting part arrange | positioned not only in the width direction both sides in addition to forming the handle part of uneven shape in the width direction center side. It is known to form an uneven shape by processing.

  By the way, in recent years, in the metal siding panel, a further high-class feeling is demanded, and it is demanded that the designability is improved by deeply forming the concavo-convex shape which becomes a pattern. When the asperity shape is deepened, a twist, a wrinkle or the like is easily formed on the metal plate. Then, when manufacturing a metal siding panel, the technique which forms uneven | corrugated shape deeply is proposed by forming a groove | channel between a handle part and a fitting part (for example, refer patent document 1).

  FIG. 4A is a partial front view of the metal plate 101 before the metal siding panel 1 is formed. FIG.4 (b) shows the figure which expand | deployed the surface shape of the cylindrical embossing roll 4 which forms uneven | corrugated shape as shown to Fig.4 (a) in the metal plate 101 on the plane. FIG. 5 (a) shows one end of the metal siding panel 1 and the developed embossing roll 4, and FIG. 5 (b) shows the other end. The manufacturing method of the metal siding panel 1 of this embodiment is demonstrated with reference to FIG. 4 (a)-FIG.5 (b).

  As the metal siding panel 1 is shown in FIG. 4 (a) and FIG.4 (b), the metal plate 101 is pressure-welded by the cylindrical embossing roll 4 in which the uneven | corrugated shape extended in the circumferential direction was formed in the surface. The main handle portion 11 and the discard portion 12 having an uneven shape symmetrical to the surface shape of the embossing roll 4 are formed.

  First, the metal plate 101 forming the surface 10a and the fitting portion 20 in the main body 10 of the metal siding panel 1 is provided in a rolled state (providing step S1). In the providing step, the strip-like metal plate 101 is attached to the manufacturing line and moved in the processing advancing direction.

  The production line is provided with a pair of embossing rolls 4 on which a handle of the metal siding panel 1 is formed. The pair of embossing rolls 4 has an upper embossing roll disposed above and a lower embossing roll positioned below (not shown). The metal plate 101 is supplied to pass between the upper embossing roll and the lower embossing roll (embossing step S2). The surface of the metal plate 101 is patterned by passing between a pair of embossing rolls.

  Here, in the embossing roll 4, the concavo-convex shape of the main roll handle portion 41 formed at the center in the width direction of the cylinder and the roll-off handle portion 42 formed at both outer side portions of the cylinder are different. In addition, between the main roll handle portion 41 and the portion where the concave and convex shapes of the roll disposal portion 42 are formed, the roll groove portion 43 in which the concave and convex shape is not formed is formed.

  The main roll handle portion 41 abuts on the widthwise central portion of the metal plate 101 and forms the main handle portion 11 in the corresponding portion of the metal plate 101. The concavo-convex shape of the roll main handle portion 41 has a maximum depth D1 (height difference) of, for example, about 3.6 mm to 5.0 mm, preferably about 3.8 mm to 4.2 mm, and the concavo-convex shape similar to that of the main handle portion 11 Is formed. The main handle portion 11 of the metal plate 101 formed by the main roll handle portion 41 constitutes the surface 10 a of the main body 10 of the metal siding panel 1 when completed.

  The roll discarding portion 42 abuts on both outer sides of the metal plate 101 and forms the discarding portion 12 in the corresponding portion of the metal plate 101. The rolled-up handle portion 42 has a maximum depth D2 shallower than the concavo-convex shape of the roll main-patterned portion 41, and accordingly, the discarded portion 12 has a maximum depth D2 shallower than the main-patterned portion 11. In addition, the disposal part 12 comprises the fitting part 20 of the metal siding panel 1 at the time of completion.

  The roll groove 43 abuts between the main handle 11 and the discard handle 12 of the metal plate 101, and forms the groove 13 in the corresponding portion of the metal plate 101 (see FIG. 4A). As shown in FIGS. 5 (a) and 5 (b), a step is formed in the roll groove 43, and the roll groove 43 includes a first roll step 431 on the side of the main roll handle 41, and a roll. It has the 2nd roll level | step-difference part 432 by the side of the scrapped part 42. The first roll stepped portion 431 extends to the side of the roll scraped portion 42 at a position shallower than the maximum depth D1 of the main roll portion 41. The second roll stepped portion 432 extends from the end of the first roll stepped portion 431 on the roll discarding portion 42 side toward the roll discarding portion 42 at the position of the maximum depth D1 of the main roll portion 41.

  As described above, in the embossing step S2, the metal plate 101 is sandwiched and passed between the pair of embossing rolls 4 in which the main roll handle portion 41, the roll scraping portion 42 and the roll groove portion 43 are formed, whereby the metal plate A main handle portion 11, a handle portion 12, and a groove portion 13 are formed on the surface 101, respectively.

  When sandwiching and passing the metal plate 101 between the pair of embossing rolls 4, if the depth of the concavo-convex shape formed on the main handle portion 11 of the metal plate 101 is too deep, the convex portions of the pair of embossing rolls 4 face each other The portion on the side edge side of the metal plate 101 is drawn into the central portion in the width direction, and the metal plate 101 is likely to be twisted or wrinkled. Here, when the maximum depth of the groove portion 13 of the metal plate 101 is made to coincide with the maximum depth D1 of the main handle portion 11, the deep portion is positioned on the side of the handle portion 12 of the main handle portion 11, Since the full width of the main handle portion 11 of the plate 101 is uniformly wound, it is difficult to form a twist or a wrinkle on the peripheral edge of the main handle portion 11.

  On the other hand, when the depth of the entire groove 13 is adjusted to the maximum depth D1 of the main handle 11, when forming the fitting portion 20, the thickness necessary for folding the handle 12 can not be secured. . That is, since the fitting portion 20 is formed by bending the disposable handle 12 in the thickness direction on the outside of the main body 10, the width in the thickness direction from the surface 10a to the back surface 10b of the main body 10 is the fitting portion It has a width to form 20. When the groove 13 is made deeper, the width between the front surface 10 a and the back surface 10 b is narrowed, so the width capable of forming the fitting portion 20 is narrowed. From the viewpoint of the bonding strength of the metal siding panel 1 and the like, the fitting portion 20 needs to have a predetermined width. Therefore, by forming the groove 13 in a two-step configuration and extending the main handle 11 side of the groove 13 shallower than the maximum depth D1 of the uneven shape of the surface 10a, the starting point to be bent to form the fitting 20 is It can approach to the surface 10a side. Further, by extending the side of the discarding portion 12 of the groove portion 13 to the position of the maximum depth D1 of the concavo-convex shape of the surface 10a, it is possible to prevent the wrinkles and the like from coming close to the main patterning portion 11.

  In the emboss process S2, after forming the concavo-convex shape on the metal plate 101 with the emboss roll 4, by bending the scraping part 12, the fitting parts 20 disposed on both sides in the longitudinal direction of the main handle 11 are formed. (Fitting portion forming step S3). Specifically, from the main handle side, the main handle portion 11 side of the groove portion 13 is referred to as a first step portion 31, and the scrapped portion 12 side of the groove portion 13 is referred to as a second step portion 32.

  As shown in FIG. 5A, on the fitting recess 21 side, the first step portion 31a is extended outward at a position shallower than the maximum depth D1 of the concavo-convex shape of the surface 10a, and then the body 10 side Bent. Further, the second step portion 32a is extended toward the lowest position of the maximum depth D1 of the concavo-convex shape, the disposable handle 12 is overlapped on the back surface side of the main body 10, folded at a predetermined width and bent outward of the main body 10 Let

  As shown in FIG. 5B, on the fitting convex portion 22 side, the first step portion 31b is extended outward at a position shallower than the maximum depth D1 of the concavo-convex shape of the surface 10a, and then the main body 10 The flat portion 33 is extended along the surface direction of the main body 10 by bending to the center side in the thickness direction. Furthermore, the second step portion 32a is extended from the flat portion 33 toward the lowest position of the maximum depth D1 of the concavo-convex shape, and the handle portion 12 is folded so as to protrude outward to form the protrusion 221 . Then, it is bent again from the base end of the protrusion 221 to the outside, and the extension portion groove 223 is formed to form the extension portion 222.

Thereafter, a sheet-like member such as paper is attached to the back surface of the metal plate 101 to form the back surface 10 b of the main body 10. Further, a filler 10c such as a urethane foam is filled between the front surface 10a and the back surface 10b (core filling, back surface forming step S4).
Thereafter, the shape is corrected and cut (correction, cutting step S5) to obtain the metal siding panel 1.

  A plurality of metal siding panels 1 formed as described above are arranged side by side according to the shape of the outer wall of a building or the like. The metal siding panel 1 is connected to each other by fitting the protrusion 221 of the other fitting protrusion 22 to one fitting recess 21 of the metal siding panel 1 adjacent in the vertical direction. A water-tight material 224 such as rubber is disposed between the protrusion 221 and the fitting recess 21. When fitted in this manner, as shown in FIG. 3, the first step parts 31 a and 31 b extend between and be adjacent to the outside (surface 10 a side) between the fitting recess 21 and the fitting protrusion 22. The joints between the metal siding panels 1 are obscured.

According to the present embodiment, the following effects are achieved.
In the present embodiment, a rectangular metal siding panel 1 which is attached to a plurality of outer walls of a building in a row is a main body 10 of the metal siding panel 1, and a main handle having a plurality of uneven shapes extending in the longitudinal direction of the metal siding panel 1 It comprised including the part 11 and the fitting part 20 which are arrange | positioned at the both sides of the longitudinal direction of the main handle 11, and can mutually be fitted between the said metal siding panels 1 which adjoin each other. Further, between the main handle 11 and the fitting portion 20, the first step 31 disposed at a position shallower than the maximum depth D1 of the concave and convex shape of the main handle 11 and the uneven shape of the main handle 11 And the second step portion 32 disposed at the position of the maximum depth D1 or more of
The second step portion 32 is provided between the main handle portion 11 and the fitting portion 20 of the metal siding panel 1 at a position greater than or equal to the maximum depth D1 of the concave and convex shape of the main handle portion 11. When forming a shape, it becomes difficult to form a twist, a wrinkle, etc. in the metal plate 101. For this reason, it becomes possible to form uneven | corrugated shape of the main handle part 11 deeply, and the designability of the metal siding panel 1 can be improved.
Further, by forming the first step portion 31 at a position shallower than the maximum depth D1 of the main handle portion 11, even if the concavo-convex shape of the main handle portion 11 is formed deep, the thickness of the fitting portion 20 is required. Since the metal siding panel 1 can be formed to have a small diameter, the designability can be improved while suitably fitting and connecting the adjacent metal siding panels 1.

  Further, in the present embodiment, the fitting portion 20 is configured to include the scrapped portion 12 having a plurality of concavo-convex shapes whose maximum depth D2 is shallower than the main handle portion 11. By forming the fitting portion 20 by the scraped portion 12 having a plurality of concavo-convex shapes having the maximum depth D2 shallower than the main handle portion 11, the concavo-convex shape can be deeply formed in the metal plate 101. The metal plate 101 can be made difficult to form a twist or a wrinkle. Therefore, manufacture of the metal siding panel 1 which improved the designability becomes easy.

  Further, in the present embodiment, the surface of the metal siding panel 1 is disposed between the first step 31 and the second step 32 at the end of the main handle 11 on which the fitting projection 22 is formed. It comprised including the plane part 33 extended to direction. When the metal siding panels 1 adjacent to each other are fitted by the fitting portion 20 by forming the flat portion 33 between the first step portion 31 b and the second step portion 32 b of the fitting convex portion 22 The flat portion 33 can be disposed to extend on the back side of the first step portion 31 on the concave portion 21 side. For this reason, since the joint part of metal siding panel 1 comrades which adjoin is covered by the 1st level difference part 31a by the side of fitting recess 21, and this 1st level difference part 31a can be supported by plane part 33, it adjoins The designability of the joint between metal siding panels 1 is improved.

Further, in the present embodiment, a method of manufacturing a rectangular metal siding panel, which is attached in a plurality on the outer wall of a building, comprises: metal between a pair of cylindrical embossing rolls 4 on the surface of which an uneven shape extending in the circumferential direction is formed; Embossing process S2 which carries out a handle on the surface by letting board 101 pass was constituted. Further, in the embossing step S2, the main handle portion 11 which constitutes the main body 10 of the metal siding panel 1 and has a plurality of concavo-convex shapes extending in the longitudinal direction of the metal siding panel 1, and both side portions in the longitudinal direction of the main handle portion 11 Between the main handle portion 11 and the second handle portion 12, the main handle portion 11 is sequentially provided with the main handle portion 12 and the main handle portion 11. A first step 31 disposed at a position shallower than the maximum depth D1 of the concavo-convex shape of the handle 11 and a second step 32 disposed at a position greater than the maximum depth D1 of the concavo-convex shape of the main handle 11 And were configured to form.
Thereby, the same effect as the above can be exhibited.

  Further, in the present embodiment, by bending the handle 12, the fitting portions 20 which are disposed on both sides in the longitudinal direction of the main handle 11 and can be fitted to each other between the adjacent metal siding panels 1 are formed. It further comprised including the fitting part formation process S3. Thereby, while preventing that a twist, a wrinkle, etc. are formed in this handle part 11, fitting part 20 which makes installation of metal siding panel 1 easy can be constituted.

The present invention is not limited to the above-described embodiment, and modifications, improvements, and the like as long as the object of the present invention can be achieved are included in the present invention.
For example, in the above-mentioned embodiment, although the main handle 11 is formed of a gal barium steel plate (registered trademark), it is not limited thereto. If it is the metal siding panel 1, a material will not be limited and a Galfan steel plate or other steel plates may be sufficient.
Moreover, in the said embodiment, although the fitting convex part 22 of the metal siding panel 1 has illustrated the state arrange | positioned at the upper end side and the fitting recessed part 21 at the lower end side, it is not restricted to this. The positions of the fitting convex portion and the fitting concave portion may be reversed, and the folding shape of the metal plate 101 is not limited to the described shape as long as the fitting structure can be formed by the unevenness.

  Further, in the above embodiment, in the groove portion 13 of the metal plate 101, the width of the step formed by the first roll step portion 431 on the surface of the embossing roll 4 is the width of each of the first step portions 31a and 31b of the metal siding panel 1. The position of the step formed by the second roll step portion 432 on the surface of the embossing roll 4 in the groove portion 13 is described as being coincident with the position of the second step portions 32a and 32b. However, they do not necessarily have to coincide on both sides of the fitting recess 21 and the fitting protrusion 22. At least the side on which the fitting recess 21 is formed (the first step 31a, the second step 32a), or the side on which the fitting protrusion 22 is formed (the first step 31b, the second step 32b) In the groove, the width of the step in the groove 13 formed by the first roll step 431 and the second roll step 432 on the surface of the embossing roll 4 and the position of the step between the first step 31 and the second step 32 Should match.

  Further, the widths of the steps of the groove 13 to be the first step 31 and the second step 32 may be different between the fitting recess 21 side and the fitting protrusion 22 side.
