Description

  The present invention relates to metal siding.

  Metal siding is widely used for building outer walls because it is highly durable against aging, lightweight and easy to handle. In addition, metal siding is inferior in design if the surface metal faceplate remains flat, and it is easy to give a cheap impression, so various uneven shapes, deep engraving patterns, etc. are formed on the surface by press molding or roll embossing. Has been granted.

  In recent years, the design of metal siding has been advanced, and those having a pattern that gives a natural impression with a rich three-dimensional effect are gaining popularity as a sense of luxury.

  As shown in FIG. 3, for example, Patent Document 1 proposes metal siding in which an edge portion of a handle portion (decoration portion) adjacent to a joint is formed flat. This metal siding is said to be excellent in three-dimensionality because the raised pattern portion X is distinguished from the joint by a clear boundary line. In addition, since the pattern portion X and the joint can be clearly distinguished, it is said that the paint for the decorative portion can be prevented from being applied to the joint portion in painting.

  However, the metal siding disclosed in Patent Document 1 is intended to express a three-dimensional effect by the concavo-convex pattern Y formed inside the handle portion X. That is, since the average height of the handle portion X itself (height in the protruding direction) is substantially uniform, the change between the handle portions X is poor. For this reason, the overall metal siding gives the impression that there are few undulations, and it cannot be said that the random and natural texture can be expressed sufficiently.

  On the other hand, as a method of giving a random and natural texture to metal siding, for example, a method of providing a pattern portion having a different height on the metal face plate on the surface is also conceivable. However, in this case, it is difficult to give depth to the surface irregularities in the pattern portion in the handle portion having a low height, and on the contrary, it is easy to give an inexpensive impression due to a decrease in the unevenness feeling. Furthermore, when painting metal siding, it is not easy to paint on a handle portion having a low height, and there is a problem that the painting process is complicated.

  The present invention has been made in view of the circumstances as described above, and it is an object of the present invention to provide a metal siding that is rich in three-dimensional effect, gives a random and natural texture, and is easy to paint.

In order to solve the above problems, the metal siding of the present invention is a metal siding having a metal face plate on which joints are formed and a plurality of handle portions having substantially the same height from the back material are provided. An inclined surface portion that is inclined obliquely inward and downward is provided in a lower area in the vertical direction of the handle portion of the portion, and a lower end of the inclined surface portion is between the inclined end portion of the lower handle portion that is opposed to the lower end portion. In addition, a cut groove for cutting inward is provided, and the inclined surface portion is characterized in that the surface unevenness is rougher than the adjacent handle portion .

In this metal siding, shallow joints and deep joints are formed as the joints, and the groove depth D1 of the shallow joints, the groove depth D2 of the deep joints, and the groove depth D3 of the cut grooves are D2> D1. It is preferable that > D3 .

In this metal siding, the inclination angle of the inclined surface portion is preferably 15 ° to 45 ° and smaller than the inclination angle of the inclined end portion .

  According to the metal siding of the present invention, the three-dimensional effect is rich, a random and natural texture can be given, and the painting work is facilitated.

It is a perspective sectional view which illustrated one embodiment of metal siding of the present invention. It is the schematic which illustrated the partial cross section of one Embodiment of the metal faceplate of the metal siding of this invention. It is the perspective sectional view showing an example of the conventional metal siding.

  In the present invention, the term “upper or upper” refers to the direction located on the upper side in the vertical direction when metal siding is applied, and “lower or lower” refers to the lower direction in the vertical direction when metal siding is applied. The direction located on the side shall be said. Hereinafter, embodiments of the present invention will be described.

  FIG. 1 is a perspective sectional view illustrating an embodiment of metal siding according to the present invention. FIG. 2 is a schematic view illustrating a partial cross section of an embodiment of the metal faceplate of the metal siding of the present invention.

  In the metal siding 1, a metal face plate 2 and a back surface material 3 are arranged in parallel with a space therebetween, and a core material 4 is filled between the metal face plate 2 and the back surface material 3.

  On the metal face plate 2, a pattern portion 5 having substantially the same height is continuously arranged in the vertical direction and the horizontal direction, and a horizontal joint 6 and a vertical joint (not shown) are provided as joints between the pattern portions 5. ) Is provided. Further, the pattern portion 5 is formed with an uneven pattern. In addition, illustration of the uneven | corrugated pattern of the pattern part 5 is abbreviate | omitted.

  Here, “the height of the handle” can be based on the length from the back material 3 to the surface of the handle 5 of the metal face plate 2. Therefore, “the heights of the handle portions are substantially equal” means that the handle portions 5 are formed on substantially the same plane. Moreover, the difference in the height of the handle portion 5 is allowed as long as it does not affect the coating of the surface. Specifically, there may be a difference of about 1 mm.

  Since the height of the handle 5 is maintained in the same manner as in the prior art, the uneven pattern can be formed deeply, and the stereoscopic effect is excellent.

  Since the height of the handle portion 5 of the metal face plate 2 is formed to be substantially equal, the metal siding 1 can uniformly apply a desired paint only to the handle portion 5 (portions other than the vertical joint and the horizontal joint 6). It is easy to paint. In addition, when painting on the vertical joints and the horizontal joints 6, it is easy to separately paint the handle 5.

  The horizontal joint 6 is composed of a plurality of types having different groove depths and groove widths. Specifically, the horizontal joint 6 also shown in FIG. 2 includes a shallow joint 61 having a groove depth D1 of about 1 mm to 3 mm and a deep joint 62 having a groove depth D2 of about 4 mm to 6 mm. .

  The shallow joint 61 is formed in a substantially V-shaped groove. The deep joint 62 is formed in a substantially U-shaped groove formed by the joint basement surface 62a, the joint bottom surface 62b, and the joint top surface 62c. The surface groove width L of the deep joint 62 can be appropriately designed within a range of 5 mm to 10 mm, for example.

  Further, the joint basement surface 62a and joint joint upper surface 62c of the deep joint 62 are inclined toward the joint bottom surface 62b toward each other. Specifically, the deep joint 62 is preferably formed such that the inclination angle θ1 of the joint upper surface 62c with respect to the joint bottom surface 62b is 45 ° to 85 °. Furthermore, the handle portion 5 adjacent to the upper side of the deep joint 62 (the right side in FIG. 2) is formed flat, and no inclination or notch is formed. For this reason, the groove depth D2 of the deep joint 62 is emphasized, and an impression rich in stereoscopic effect can be given.

  A part of the handle portion 5 provided on the metal face plate 2 is provided with an inclined surface portion 7 that is inclined inward and downward in the lower region. For example, the inclination angle θ2 of the inclined surface portion 7 can be suitably designed within a range of 15 ° to 45 °, for example. The inclination angle θ2 of the inclined surface portion 7 is smaller than the inclination angle of the inclined end portion 8 of the opposite lower (left side in FIG. 2) handle portion 5, and the width M (length in the vertical direction) is slightly longer. ing. Further, the inclined surface portion 7 is formed to have a rougher surface asperity than the handle portion 5. And the lower end of the inclined surface part 7 is provided with a cut groove 9 that cuts inwardly between the inclined end part 8 of the opposed lower handle part 5. The cut groove 9 can be formed with a groove depth shallower than that of the shallow joint 61, and the groove depth D3 can be exemplified by about 1 mm to 2 mm, for example.

  Since the cut groove 9 is formed at the lower end of the inclined surface portion 7 of the metal face plate 2, a dark black shadow can be reflected in this portion. Furthermore, the inclined surface portion 7 of the metal face plate 2 can express a slightly pale shadow by the inclination and surface irregularities. Therefore, in the vicinity of the cut groove 9, a gradation effect in which the shadow becomes deeper as the pattern portion 5 approaches the cut groove 9 is exhibited, and a deeper impression can be given. For this reason, even if the heights of the handle portions 5 are formed to be substantially equal, there is a step between adjacent handle portions 5 and an illusion and impression that is rich in undulations can be given. It can express natural texture and can produce a high-class feeling.

  Further, when the top color is applied only to the pattern portion 5 and the top color is not applied to the inclined surface portion 7, the color of the inclined surface portion 7 can be expressed more darkly, so that the gradation effect is further enhanced. It is possible to enhance and enhance the sense of quality.

  Further, in the metal siding 1, the groove depth D1 of the shallow joint 61 of the metal face plate 2, the groove depth D2 of the deep joint 62, and the groove depth D3 of the cut groove 9 are in a relationship of D2> D1> D3. For this reason, a change arises in the depth of the groove | channel formed in the metal face plate 2, and a three-dimensional effect is further conspicuous.

  The metal face plate 2 has a thickness of about 0.2 to 0.5 mm, and the material is a steel plate such as a normal steel plate, a plated steel plate, a coated steel plate, a stainless steel plate, an aluminum plate, a copper plate, zinc or nickel in these metals. An alloy plate containing the above can be used. Further, the matte treatment can be performed by attaching acrylic beads, plastic beads, or the like to all or part of the surface of the metal face plate 2.

  The metal face plate 2 provided with the handle 5 is filled with the core material 4 on the back side, and then the back face material 3 is bonded to form the metal siding 1. Examples of the core material 4 include foamed resins such as polyurethane resin foam, polyisocyanurate foam, polystyrene foam, phenol resin foam, vinyl chloride resin foam, and materials generally used as heat insulating materials such as rock wool and gypsum board. can do. For the back material 3, a plain steel plate, a stainless steel plate, a coated steel plate, or the like can be used.

  The metal siding of the present invention is not limited to the above form. For example, the horizontal joint formed with the cut groove on the surface of the metal face plate may be either a shallow joint or a deep joint. Further, horizontal joints (shallow joints, deep joints) and vertical joints having different groove depths and groove widths can be mixed.
