JP-A-2006-3465 JP-A-9-1111915

  Since the wall material is a member that forms the outer wall, the design affects the design of the outer wall. In recent years, a wall material having a flat appearance without a pattern or the like on the surface has been demanded from the background of seeking an outer wall of a simple design. In response to such a request, in the conventional wall materials disclosed in Patent Documents 1 and 2, etc., a method using a flat metal plate as a surface material can be adopted.

  Here, since the wall material forms an outer wall, the surface material may be deformed, for example, when an object collides from the outside, and the middle material is made of the foam heat insulating material. The surface material may be deformed even under pressure. Then, when the surface material is a flat surface as described above, the deformation is easily noticeable. For this reason, it has been difficult to realize a wall material that has a flat appearance and does not easily lose its design effect.

  Therefore, it is desired to realize a wall material that has a flat appearance and is less likely to lose its design effect in a vertically installed state.

  The wall material according to the first invention is characterized in that a ridge is formed on the surface, and no shadow is produced on the surface in a vertically installed state.

  According to this configuration, since the surface is reinforced by the protrusions provided in advance, the surface is not easily deformed, and further, since the surface is provided with no shading, a flat appearance is maintained, A wall material that does not easily lose its design effect is realized.

  Moreover, the wall material which concerns on 2nd invention is characterized by the height of the protrusion formed in the surface being 0.3 mm or less.

  According to this configuration, since the surface is reinforced by the protrusions provided in advance, the surface is not easily deformed, and further, the protrusions are provided so as not to be shaded on the surface, so that a flat appearance is maintained. Thus, a wall material that does not easily lose its design effect is realized.

  Hereinafter, preferred embodiments of the present invention will be described. However, the scope of the present invention is not limited by the preferred embodiments described below.

  As one aspect, the wall material according to the present invention is preferably such that the protrusion continuously extends linearly from one end to the other end of the surface.

  According to this configuration, since the ridge functions as a rib that continues from end to end of the surface of the wall material, it is possible to further suppress surface deformation.

  As one aspect, the wall material according to the present invention preferably includes a plurality of the protrusions, and the protrusions are arranged over the entire surface in parallel to each other in a direction intersecting the extending direction.

  According to this structure, since the protrusion is formed over the entire surface in parallel with each other, it is possible to suppress deformation of the entire surface.

  As one aspect, the wall material according to the present invention is preferably arranged regularly at equal intervals in the intersecting direction.

  According to this configuration, since the plurality of protrusions are regularly arranged at equal intervals, the entire surface of the wall material is reinforced substantially uniformly.

  As one aspect, the wall material according to the present invention is preferably such that the surface has a rectangular shape and the protrusions extend in the short direction of the surface.

  According to this structure, since it is a short protrusion, a rib effect is high and it is possible to reinforce the surface of a wall material effectively.

  In one aspect of the wall material according to the present invention, it is preferable that the protrusion has a ridge portion and at least a pair of inclined surfaces, and the inclination angle of the inclined surface is greater than 0 ° and 2 ° or less.

  According to this configuration, the protrusions are hardly noticeable on the surface of the wall material.

  Further features and advantages of the present invention will become more apparent from the following description of exemplary and non-limiting embodiments described with reference to the drawings.

The perspective view of wall material. FIG. 2 is a perspective cross-sectional view showing a cross section taken along line II-II in FIG. 1. Schematic of how to install the first wall material. Schematic of the method of installing a 2nd wall material following a 1st wall material.

  Embodiment of the wall material which concerns on this invention is described with reference to FIGS. This embodiment demonstrates the example which applied the wall material which concerns on this invention to the wall material 100 installed in the outer wall of a building. In addition, the description of the up-down direction in the following description shall represent the up-down direction in the installation state of the wall material 100. FIG. In addition, in the description of the front and back directions, the outdoor side in the installed state of the wall material 100 is the front side, and the indoor side is the back side.

[Configuration of wall material 100]
The wall material 100 includes a surface material 1, an intermediate material 2, a backing material 3, a fitting convex portion 4, a fitting concave portion 5, and an upper protruding portion 6 (FIG. 1). The wall material 100 has a substantially rectangular shape. As will be described later, the wall member 100 is installed such that its short side is along the vertical direction. In the installed state, the fitting convex portion 4 is upward, the fitting concave portion 5 is downward, To position. In such an installation state, no shadow is generated on the surface of the surface material 1 (that is, the surface of the wall material 100).

  The surface material 1 is a hot-dip aluminum / zinc alloy-plated steel sheet coated on the front and back surfaces, and has a plurality of protrusions 11 on the surface. Each protrusion 11 is provided so as to continuously extend in a straight line from one end to the other end in the short direction of the surface material 1. Further, the plurality of protrusions 11 are provided so as to be regularly arranged at equal intervals over the entire surface material 1 in parallel to each other in a direction intersecting with the extending direction.

  As shown in FIG. 2, each protrusion 11 has two slopes 12 and a ridge 13 formed by the two slopes 12. Each of the protrusions 11 is also provided so that the ridge 13 extends in the longitudinal direction, and the ridge 13 is provided in a direction parallel to the short side of the wall member 100. As will be described later, the protrusions 11 are designed with the intention of making them visually inconspicuous, thereby obtaining a design effect that gives the impression that the surface of the wall material 100 is flat.

  In the present embodiment, the intermediate material 2 is a heat insulating material made of, for example, foamed polyisocyanurate. By providing a heat insulating material as the middle material 2, it is possible to impart a heat insulating function to the outer wall constructed by installing the wall material 100.

  In the present embodiment, the backing material 3 is, for example, an aluminum foil that has been subjected to anticorrosion coating.

  The wall material 100 includes a fitting convex portion 4 at the upper end portion and a fitting concave portion 5 at the lower end portion, and the fitting convex portion 4 and the fitting concave portion 5 are configured to be fitted to each other. Has been. Further, both the fitting convex portion 4 and the fitting concave portion 5 are provided over substantially the entire long side of the wall material 100.

  The upper protrusion 6 is provided in a manner that protrudes upward over substantially the entire length of the long side of the upper end of the back surface of the wall material 100, and is fixed to the wall base with a nail or the like. The upper protrusion 6 is made of the same metal plate as the surface material 1.

[Effects of wall material 100]
Due to the temperature change of the wall material 100, the foamed polyisocyanurate forming the intermediate material 2 is deformed by expansion and contraction, and therefore the wall material 100 can be deformed. The deformation is particularly expressed in a form in which the surface material 1 is curved. Here, since the surface of the surface material 1 is substantially flat, even if it is slightly curved, the surface material 1 is easily noticeable visually. Therefore, when the surface material 1 is curved, the surface of the wall material 100 is flat. The design effect that gives the impression may be lost. However, since the plurality of protrusions 11 are provided on the surface of the surface material 1, the surface material 1 functions as a metal plate formed in a so-called bellows shape, thereby following the deformation of the intermediate material 2. Therefore, it is difficult to bend. Thus, since it is difficult to bend, even if the intermediate material 2 is deformed by a temperature change, the design effect on the appearance of the wall material 100 is not easily lost.

[Configuration of ridge 11]
Subsequently, the configuration of the protrusion 11 suitable for expressing the above-described effects will be described. In the following description, “shade” refers to a shadow that can be generated when the wall material 100 is installed vertically and light is irradiated on the surface of the wall material 100 from a light source located higher than the wall material 100. Is to be mentioned.

  First, the height of the protrusion 11 with respect to the surface of the surface material 1 is 0.3 mm or less. If the height of the ridge is within the above range, the shadow of the ridge 11 due to sunlight is less likely to occur on the surface of the surface material 1, so that the ridge 11 is less noticeable on the surface of the surface material 1, and the wall material. It is easy to obtain a design effect that gives an impression that the surface of 100 is flat. In addition, it is preferable that the height of the protrusion 11 is 0.1 mm or less.

  Second, the inclination angle of the inclined surface 12 with respect to the surface of the surface material 1 is 2 ° or less. If the inclination angle of the slope 12 is within the above range, the shade 11 is not easily shaded by the sunlight on the surface of the surface material 1, so that the projection 11 is less noticeable on the surface of the surface material 1. It is easy to obtain a design effect that gives an impression that the surface of 100 is flat. The inclination angle of the slope 12 is preferably 1 ° or less.

  Third, the length of the protrusion 11 in the longitudinal direction is preferably about 20 mm. If the length of the ridge in the longitudinal direction is within the above range, the ridge 11 is not conspicuous on the surface of the surface material 1, so that a design effect that gives an impression that the surface of the wall material 100 is flat is obtained. It is easy to be done.

  Fourth, it is preferable that the ridge portion 13 does not have a width or has a curved shape that curves so as to protrude to the front side. When the ridge portion 13 has the above shape, the shade 11 is not easily shaded by the sunlight on the surface of the surface material 1, so that the ridge 11 is less noticeable on the surface of the surface material 1, and the surface of the wall material 100 is It is easy to obtain a design effect that gives an impression of being flat.

  Fifth, the distance between adjacent ridges 13 is preferably about 20 mm. If the distance between adjacent ridges 13 is about 20 mm, the number of ridges 11 does not become excessive, and the ridges 11 are hardly noticeable. At the same time, since the ratio of the flat portion on the surface of the surface material 1 can be reduced, it is easy to obtain the effect of suppressing the above-described bending deformation. Thus, when the separation distance of the ridge 13 is within the above range, a design effect that gives an impression that the surface of the wall member 100 is flat is easily obtained.

  Sixth, it is preferable that the protrusions 11 are provided about 50 per 1 m in the long side direction of the wall material 100. When the number of the ridges 11 is the above number, the effect of suppressing the above-described curved deformation is easily obtained, and at the same time, the ridges 11 are not easily noticeable. Thus, when the number of the protrusions 11 is within the above range, a design effect that gives an impression that the surface of the wall member 100 is flat is easily obtained.

[Construction method of wall material 100]
Then, the construction method which installs the wall material 100 in the outer wall of a building is demonstrated with reference to FIG.

  First, the first wall member 100A is fixed to the outer wall (FIG. 3).

To do. At this time, the fixing member 300 is fixed in such a manner as to penetrate the upper protrusion 6 of the first wall member 100A.

  Next, the second wall member 100B is fixed above the first wall member 100A (FIG. 4). At this time, the fitting convex portion 4 of the first wall member 100A and the fitting concave portion 5 of the second wall member 100B are fitted. Note that the second wall member 100B is fixed to the base 200 in a manner in which the fixing member 300 is fixed to the upper protrusion 6 as in the case of the first wall member 100A.

  At this time, in order to prevent water from entering from the fitting portion to the back side of the wall material 100, it is preferable to interpose the sealing material 7 in the fitting portion. The sealing material 7 may be, for example, a thermoplastic elastomer. The sealing material 7 may be inserted into the fitting recess 5 at the stage of manufacturing the wall material 100, or inserted between the first wall material 100A and the second wall material 100B at the construction stage. May be.

  Thereafter, similarly, the wall material 100 is sequentially installed in such a manner that the fitting concave portion 5 of the upper wall material 100 is fitted to the fitting convex portion 4 of the lower wall material 100. Further, a gap generated between the wall members 100 adjacent in the left-right direction is sealed by a known connecting member.
