[Technical field to which the device belongs]

 The present invention relates to a metal siding material used as an exterior material for houses and structures.

[0002]

[Prior art]

 In recent years, lightweight and heat-insulating metal siding materials have been widely used as exterior materials for houses and structures. This metal siding material consists of a surface material consisting of a thin metal plate that is shaped like a gutter in cross section and provided with engaging parts on the upper and lower sides, and a synthetic resin foam filled in the gutter-shaped part of this surface material. And a back surface material made of a sheet-like material that covers the back surface of the core material.

However, the metal siding material is a laminated body of three different kinds of materials such as a surface material, a core material and a back surface material, and there is a defect that the entire metal siding material is deformed because the degree of expansion and contraction of each material is different. For this reason, it is necessary to give a small embossed pattern to the entire thin coated metal plate used as a surface material to enhance its rigidity, so that the surface design is limited.

However, in recent years, there has been a strong demand for high-class designs, and in particular, large patterns have been favored. A brick pattern is required as a representative of large patterns, but in the current method for producing metal siding materials, the design is applied to thin coated metal plates used as surface materials by embossing with embossing rolls, so the embossing depth However, there was no production of a pattern that required joints with a certain width without embossed patterns such as brick patterns. Some parts of the product have an irregular large pattern (steel flat stone pattern) with joints in a different color from the main body, but this metal siding material also has embossed parts corresponding to the joints. It has been processed, and since it is painted twice, it is expensive.

In addition, since the brick pattern generally has a shape in which bricks of the same size are regularly piled up, when the metal siding materials are vertically and horizontally connected and horizontally stretched, the metal siding that is vertically connected is used. Not only will it be necessary to align the vertical joints of the timbers in a straight line, but it will also be necessary to align the lengths of the bricks in the metal siding that are connected left and right to the same length. However, since the metal siding material is usually marketed in a state of being cut to a length of about 6 shaku, the vertical joints of the metal siding material connected vertically are aligned in a straight line, or the metal siding material connected left and right is aligned. In order to adjust the length of the brick part of the siding material to the same length, it is necessary to cut the both ends of the metal siding material and lay them horizontally, so that not only the material loss is large, but also the construction is troublesome. was there.

[0006]

[Problems to be solved by the device]

 The present invention solves the above-mentioned drawbacks of conventional metal siding materials, and is a metal siding material with a brick pattern, which is a large pattern that meets the requirements of recent high-class designs. It is an object of the present invention to provide a metal siding material for horizontal lining, which does not require material loss and has good workability, because it is not necessary to align the positions of vertical joints in the case of horizontal lining.

[0007]

[Means for Solving the Problems]

 As a result of earnest research to solve such problems, the present inventors have made a surface material and a gutter-shaped portion of the surface material, which are made of a thin metal plate having a substantially gutter-shaped cross section and provided with engaging portions on the upper and lower sides. In a metal siding material for horizontal lining, which is composed of a core material made of synthetic resin foam filled in and a back surface material made of a sheet-like material covering the back surface of the core material, the surface material is embossed. At this point, a brick part having at least a part of a fine uneven pattern and a horizontal joint part and a vertical joint part having no uneven pattern, which are recessed more than the brick part, are formed between the brick parts. The metal siding material according to the present invention was completed by clarifying that it is sufficient to form a pattern, form the spaces corresponding to the horizontal joints at regular intervals, and form the spaces corresponding to the vertical joints at irregular intervals. I did.

In such a metal siding material, the width of the portion corresponding to the horizontal joint in the brick pattern of the surface material is formed when the engaging portions provided on the upper side and the lower side of the surface material are engaged with each other. If the width of the joint is approximately the same as the width of the joint, it may have an appearance similar to that of the front surface made of bricks in the installed state, and may have a good design effect. I have investigated.

[0009]

[Embodiment of device]

 Hereinafter, embodiments of the metal siding material according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of an embodiment of a metal siding material according to the present invention, FIG. 2 is an enlarged cross-sectional view taken along line X-X of FIG. 1, and FIG. 3 is a processing of one embodiment of a metal siding material according to the present invention. FIG. 4 is a perspective view showing a state, and FIG. 4 is an enlarged explanatory view of a brick pattern on the surface of one embodiment of the metal siding material according to the present invention.

In the drawings, reference numeral 1 is a surface material formed of a thin metal plate that is formed into a substantially gutter-shaped cross section and provided with engaging portions A and B on the upper and lower sides over the entire length thereof. Painted galvanized steel plate, aluminum alloy coated plate, coated hot-dip zinc-aluminum alloy plated steel plate, painted stainless steel plate, and other coated metal plates. A brick part 1a having a pattern such as a sandstone tone or a split brick tone, and a horizontal joint corresponding part 1b and a vertical joint corresponding part 1c which are respectively recessed between the brick part 1a and are larger than the brick part 1a. Are formed to form a brick pattern, the horizontal joint corresponding portions 1b are formed at regular intervals, and the vertical joint corresponding portions 1c are formed at irregular intervals.

The shape of the brick pattern of the surface material 1 will be described in more detail. As shown in FIG. 4, in order to deeply emboss the brick portion 1a that becomes a convex portion, the edge portion of the brick portion 1a must be deeply embossed. It is necessary to examine the taper angle. For example JISA6711- ₁₉₇₉ the edge of the "gypsum composite metal siding" in accordance with using large painted galvanized steel sheet 0.27mm, yet elongation is the lowest thickness within the steel plate brick portion 1a vertically into When embossed, cracks occur within 1.3 mm. Therefore, when embossing, the taper angles of the surfaces that will be the upper and both edges of the brick portion 1a when horizontally installed are set to 60 °, and the lower edge of the brick portion 1a when horizontally installed. If the taper angle of the part surface is 45 ° and the radius of curvature of the corner part of the brick part 1a is 2.5 to 5.5 mm, the horizontal joint corresponding part 1b and the vertical joint corresponding part 1c will have deep embossing of 1.3 mm or more. As a result, it is possible to generate a feeling of unevenness that is clearly distinguished from the brick portion 1a. When such a taper angle is adopted, a horizontal brick joint portion 1b is shaded during horizontal lining, and the joint can be seen deeper, which is preferable as a deep brick pattern.

The width of the horizontal joint corresponding portion 1b in the brick pattern of the surface material 1 is formed when the engaging portions A and B provided on the upper side and the lower side of the surface material 1 are engaged with each other. If the width is the same as the width of the joint portion 4 to be formed, the appearance is the same as if the entire front surface were made of bricks in the state where the metal siding material was installed horizontally, and the design effect was excellent. It is preferable that

Numeral 2 is a core material made of a synthetic resin foam, which is mainly filled in the gutter-shaped portion of the surface material 1 for imparting heat insulating and soundproofing functions, and the material thereof is polyurethane foam or polyisocyanurate foam. , Phenol foam, etc. as the main material, with flame retardants and flame retardant aids added to them as needed.

In order to maintain the weather resistance of the core material 2 and to prevent the core material 2 from collapsing due to dew condensation or generating mold, 3 is a sheet-like material coated on the back surface of the core material 2. It is a backing material made of kraft paper, aluminum vapor deposition kraft paper, aluminum foil laminated paper, metal plate, etc.

EFFECTS OF THE INVENTION The metal siding material according to the present invention has a brick pattern in which the horizontal joint portions and the vertical joint portions, which have no uneven pattern between the brick portions, are recessed more than the brick portions. Since the corresponding horizontal joints are formed at regular intervals, the engagement provided on the upper and lower sides of the surface material when connecting to the left and right during horizontal installation. It is only necessary to place the parts so that they are located at the same height, and since the vertical joint-equivalent parts are formed at irregular intervals, it is necessary to connect the upper and lower parts when installing horizontally. Even if the vertical joints of the surface material are not aligned with each other, the finished product can be finished without any discomfort, and the joint alignment can be eliminated, which facilitates construction and eliminates material loss. Of.

The surface material made of a thin metal plate having a substantially gutter-shaped cross section and provided with engaging portions on the upper side and the lower side is embossed on the surface thereof and has a fine uneven pattern on at least a part thereof. The brick portion is formed by forming a brick portion and a portion corresponding to a horizontal joint and a vertical joint portion, each of which has no concave-convex pattern and is formed between the brick portion and the brick portion, which is larger than the brick portion. The surface roughness of the surface siding material is increased due to the minute unevenness pattern and the horizontal and vertical joint corresponding parts between the bricks, so the metal siding material is different in the degree of expansion and contraction of each material constituting the metal siding material. Since the overall deformation is prevented, not only can a brick-patterned metal siding material, which is a large pattern that meets the requirements of high-class designs in recent years, be manufactured in the same manufacturing process as before. The horizontal joints and vertical joints are formed so that they are recessed more than the bricks and have no uneven pattern, so that they can be clearly distinguished. Therefore, the bricks and horizontal joints and vertical joints can be clearly distinguished. Since it is not necessary to separate the colors from each other and it is sufficient to use a mono-color material, the material for the surface material can be made inexpensive, so that it is possible to provide a metal siding material that is inexpensive even though it is a high-class design. .

Further, the width of the portion corresponding to the horizontal joint in the brick pattern of the surface material is the joint portion formed when the engaging portions provided on the upper side and the lower side of the surface material are engaged (one metal The joint bottom may be formed only at the upper or lower end of the siding material and the joint bottom may be formed at the upper and lower ends of the engaged metal siding material). Then, the effect as the high-grade design becomes more remarkable.

The practical value of the metal siding material according to the present invention having such various effects is extremely great.
