It is a front view which shows the metal wall material by Embodiment 2 of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Embodiment 1
1 is a front view showing a metal wall material 1 according to Embodiment 1 of the present invention, FIG. 2 is a rear view showing the metal wall material 1 of FIG. 1, and FIG. 3 is a line III-III in FIG. It is sectional drawing of the metal wall material 1 which follows, and FIG. 4 is explanatory drawing which shows the example of the flow pattern provided in the top plate of FIG.

The metal wall material 1 shown in FIGS. 1 to 3 is a substantially rectangular member in plan view having a width direction (depth direction) and a longitudinal direction (width direction), and is disposed on a wall foundation in a wall of a house or the like, for example. It is As will be described later with reference to the drawings, the metal wall material 1 has a short direction along the vertical direction 5 of the wall and a longitudinal direction along the lateral direction 6 (direction parallel to the eaves) perpendicular to the vertical direction 5 It is placed on the wall base (see FIG. 5). Hereinafter, the lateral direction of the metal wall material 1 and the top plate 20a of the front base material 2 is referred to as the vertical direction 1S, and the longitudinal direction thereof is referred to as the lateral direction 1L. As shown in FIGS. 1 to 3, the metal wall material 1 has a front substrate 2, a back substrate 3 and a core material 4.

<About base material>
The front substrate 2 is a metal member made of a metal plate, and is a member that appears on the outer surface of the wall when the metal wall material 1 is disposed on the wall substrate. As particularly shown in FIG. 3, the front substrate 2 is provided with a box-like main body 20 having a top plate 20 a and a peripheral wall 20 b.

As a metal plate which is a material of front base material 2, a hot-dip Zn-based plated steel plate, a hot-dip Al plated steel plate, a hot-dip Zn-plated stainless steel plate, a hot-dip Al plated stainless steel plate, a stainless steel plate, an Al plate, a Ti plate, a painted hot-dip Zn system It is possible to use a plated steel plate, a painted molten Al plated steel plate, a painted molten Zn-based plated stainless steel plate, a painted molten Al plated stainless steel plate, a painted stainless steel plate, a painted Al plate or a painted Ti plate. When making the front base 2 into a box shape, it is preferable to draw the steel plate to construct the front base 2. This is because work hardening occurs on the peripheral wall 20b by drawing the steel plate, and the wind pressure performance of the metal wall material 1 can be improved. Moreover, it is because the surrounding wall 20b can be made into the wall surface which follows the circumferential direction of the surface base material 2. FIG.

<About back substrate>
The back substrate 3 is a member disposed on the back side of the front substrate 2 so as to close the opening of the main body 20. The opening of the main body portion 20 is edged by the inner edge of the anti-top plate side end portion of the peripheral wall 20 b of the main body portion 20. As the back substrate 3, a lightweight material such as aluminum foil, aluminum-deposited paper, aluminum hydroxide paper, calcium carbonate paper, resin film or glass fiber paper can be used. By using these lightweight materials for the back substrate 3, it is possible to prevent the weight of the metal wall material 1 from increasing.

<About core material>
The core 4 is made of, for example, a foamed resin, and is filled between the main body 20 and the back base 3. There is no restriction | limiting in particular as a raw material of the core material 4, A urethane, a phenol, a nurate resin etc. can be used. However, for wall materials, it is essential to use non-combustible certified materials. In the noncombustible material qualification test, a heat generation test in accordance with the ISO 5660-1 corn calorimeter test method is performed. In the case where the foamed resin to be the core 4 is urethane or the like having a large calorific value, the thickness of the core 4 can be reduced, or the foamed resin can contain inorganic foamed particles. The core material is applied to the back surface of the front surface substrate 2 rather than a mode in which a backing material such as a resin sheet is attached to the back surface of the front surface substrate 2 by filling the foamed resin between the main body 20 and the back substrate 3 4 can be firmly adhered, and the performance required for wall materials such as rain noise, heat insulation and anti-stepping resistance can be improved.

<About the top plate of the front substrate>
As shown in FIG. 1, a plurality of binding holes 21, a plurality of edge display portions 22, a plurality of lateral direction display portions 23 and an auxiliary display portion 24 are provided on the top plate 20 a of the front base 2.

The fastening holes 21 are provided apart from each other in the lateral direction 1L of the top plate 20a, and indicate the position where the fastening members 8 (see FIG. 6) are driven into the metal wall material 1. The fastening member 8 is formed of, for example, a screw or a nail, and is for fastening the metal wall material 1 to the wall base. In the present embodiment, the bonding holes 21 are described as being provided in the front substrate 2. However, for example, non-opening marks indicating the positions where the bonding members are driven, such as printed symbols and irregularities are bonding holes. 21 may be provided on the top plate 20a.

The plurality of edge display portions 22 are projecting bodies provided at the edge of the top 20a. The edge of the top 20 a is a region having a certain width from the end of the top 20 a and extending so as to surround the top 20 a. The edge display portion 22 can be formed by subjecting a metal plate which is a material of the front substrate 2 to a forming process such as pressing or embossing. For this reason, compared with the case where a notch is formed in the edge part of surface base material 2, edge indicator 22 can be easily formed in surface base material 2, and the manufacturing cost of metal wall material 1 can be reduced. As described later with reference to the drawings, when the metal wall material 1 is placed on the wall base together with the other metal wall material 1, the edge display portion 22 can be used to position the metal wall material 1 . In addition, when a notch is provided at the end of the wall material, the notch may be caught by another member and the wall material and other members may be damaged, but in the case of the configuration of the present embodiment, such a case The occurrence of problems can also be avoided.

In the metal wall material 1 of the present embodiment, a pair of side edge display portions 22s provided on both edges of the top plate 20a in the lateral direction 1L as the edge display portion 22 and the lower side of the top plate 20a A lower edge display portion 22n and an upper edge display portion 22m provided on the upper side of the top plate 20a are provided. The lower edge display portion 22n and the upper edge display portion 22m are disposed at the central position in the vertical direction 1S of the top plate 20a. By using the side edge display portion 22s, the lower edge display portion 22n, and the upper edge display portion 22m, the metal wall members 1 can be more reliably aligned in the vertical direction 5 and the lateral direction 6 of the roof. However, any of the side edge display portion 22s, the lower edge display portion 22n, and the upper edge display portion 22m may be omitted. That is, at least one edge display portion 22 serving as an alignment mark may be provided on the top plate 20a.

Each of the edge display portions 22 is formed to be a triangle when viewed in a plane as shown in FIG. 1, and the corner portion is disposed to face the outer side of the edge of the top plate 20a. The outer side of the edge of the top 20 a means a region where the top 20 a does not extend beyond the end of the top 20 a. By arranging the corner portion to face outward of the edge portion of the top plate 20a, the position indicated by each edge display portion 22 can be made clearer, and the accuracy of alignment of the metal wall material 1 can be improved. It can be improved. The tops of the corners of the lower edge display portion 22n and the upper edge display portion 22m are located at the center position of the top plate 20a in the lateral direction 1L. The outer shape of each edge display portion 22 is preferably an outer shape having a corner when viewed in a plane as shown in FIG. 1, and may be, for example, a rhombus.

Lateral extending the width W _n of the lower edge the display unit 22n along the lateral 1L of the top plate 20a is narrower than the vertical direction extending a width W _nm of the lower edge the display unit 22n along the vertical direction 1S of the top plate 20a ing. In other words, the lower edge display portion 22n is thin in the vertical direction 1S and long in the lateral direction 1L. Since the lower edge display portion 22 n is provided below the top plate 20 a, it is assumed that the lower edge display portion 22 n is exposed without being covered by another metal wall material. As described above, by forming the lower edge display portion 22n to be elongated, it is possible to reduce the possibility that the lower edge display portion 22n may inhibit the flow of water such as rain water while securing the visibility of the lower edge display portion 22n. Can. Further, as described later, when the top plate 20a is provided with a pattern having unevenness, the lower edge display portion 22n is formed to be elongated, so that the lower edge display portion 22n naturally matches the pattern, and the lower edge is displayed. The effect that the display unit 22n does not inhibit the design of the pattern can also be obtained.

The plurality of lateral direction display portions 23 are projecting bodies disposed along the lateral direction 1L of the top 20a. That is, the plurality of lateral direction display portions 23 are arranged apart from one another on a straight line extending in the lateral direction 1L. In this manner, when the plurality of lateral direction display portions 23 are arranged along the lateral direction 1L, when the other metal wall material is stacked and arranged on the metal wall material 1, these metal wall materials are used. It can be arranged in parallel more reliably. In addition, when arrange | positioning another metal wall material on the metal wall material 1, it is preferable that the horizontal direction display part 23 is arrange | positioned in the position concealed by another metal wall material.

By using the side edge display portion 22s, the lower edge display portion 22n, and the upper edge display portion 22m described above, alignment of the metal wall members 1 can be performed in the vertical direction 5 and the lateral direction 6 of the wall. However, even if any of the side edge display portion 22s, the lower edge display portion 22n, and the upper edge display portion 22m is omitted by using the horizontal direction display portion 23, another metal may be formed on the metal wall material 1 The house wall 1 can be arranged easily and accurately. Moreover, the metal wall material 1 may be cut | disconnected and used for arbitrary dimensions in the roof of a roof or a ridge part. When the metal wall material 1 is cut, part of the edge display portion 22 may be missing. Even in such a case, easy and accurate alignment can be achieved by aligning the lower end of the metal wall material 1 with reference to the lateral display portion 23. In addition, the lower side edge of each horizontal direction display part 23 is extended along 1 L of horizontal directions.

In the metal wall material 1 of the present embodiment, a pair of side display portions 23s provided at both edges of the top plate 20a in the lateral direction 1L as the lateral direction display portion 23, and the center of the top plate 20a in the lateral direction 1L. And a pair of intermediate display portions 23i disposed in the middle between the side display portions 23s and the central display portion 23c. The side display unit 23s, the center display unit 23c, and the middle display unit 23i are configured by three projections spaced apart in the lateral direction 1L. The

display portions

23s, 23c, and 23i are configured by the three protrusions spaced apart in the horizontal direction 1L, so that the central position of each

display portion

23s, 23c, and 23i in the horizontal direction 1L can be easily understood. can do. This configuration is particularly useful when cutting the metal wall material 1 along a straight line extending in the vertical direction 1S, for example, when cutting the metal wall material 1 in half at a central position in the lateral direction 1L. The number of projections constituting each of the

display portions

23s, 23c, and 23i is preferably an odd number, and may be, for example, one or five. However, from the viewpoint of making the central position of the horizontal display unit 23 easy to understand while providing the horizontal display unit 23 with a spread in the horizontal direction 1L, the number of projections constituting the horizontal display unit 23 is three or more. More preferably, it is an odd number.

The auxiliary display unit 24 is a projecting body elongated in the vertical direction 1S at the center in the horizontal direction 1L of the top plate 20a and at an intermediate position in the vertical direction 1S of the top plate 20a. The auxiliary display unit 24 of the present embodiment has a triangular outer shape which is elongated in the vertical direction 1S, and is arranged in the vicinity of the central display unit 23c. When another metal wall material is stacked and arranged on the metal wall material 1, the end surface of the other metal wall material and the auxiliary display portion 24 can be arranged together. In addition, when arranging the other metal wall material on the metal wall material 1, the auxiliary display unit 24 is preferably arranged at a position where it is hidden by the other metal wall material.

The top plate 20a can be formed with a pattern of irregularities. As a pattern, for example, a flow pattern as shown in FIG. 4 can be adopted. The dark parts in FIG. 4 indicate the tops of the convex parts constituting the pattern. The flow pattern is a pattern in which asperities are linearly arranged in the vertical direction 1S of the top plate 20a so as not to obstruct the flow of moisture such as rain water along the vertical direction 1S of the top plate 20a. As the flow pattern, a pattern as disclosed in JP-A-2015-71927 or the like can also be adopted. When a pattern consisting of asperities is formed on the top plate 20a, the above-mentioned pattern is formed around the edge display portion 22, the horizontal direction display portion 23, and the auxiliary display portion 24 (for example, in the area shown by the dashed dotted line in FIG. 1). It is preferable that a flat portion 25 not formed is formed. The flat portion 25 appears as a bright portion located around the dark portion corresponding to the edge display portion 22, the horizontal direction display portion 23, and the auxiliary display portion 24 in FIG.

The upper surface of the edge display portion 22, the horizontal direction display portion 23, and the auxiliary display portion 24 may have the same color as the top plate 20a, but in the periphery of the edge display portion 22, the horizontal direction display portion 23, and the auxiliary display portion 24. It is preferable to be colored in a color different from the color of the top plate 20a. Thus, by coloring the top surface of the edge display portion 22, the horizontal direction display portion 23, and the auxiliary display portion 24 and the top plate 20a around them with different colors, the edge display portion 22, the horizontal direction display portion 23, and The visibility of the auxiliary display unit 24 can be improved. For example, when the top panel 20a around the edge display portion 22, the horizontal direction display portion 23, and the auxiliary display portion 24 is brown, the upper surfaces of the edge display portion 22, the horizontal direction display portion 23, and the auxiliary display portion 24 are white and yellow. , Red or black.

In particular, the edge display portions 22 other than the lower edge display portion 22n, the lateral direction display portion 23, and the auxiliary display portion 24 are hidden by the other metal wall members 1 and are located in an invisible portion after construction, and thus have a distinctive color. That is, complementary colors of their surrounding colors and similar colors of the complementary colors can be selected.

On the other hand, since the lower edge display portion 22 n is located in a place where it can be seen even after the wall construction, it is preferable to select a similar color of the color around the lower edge display portion 22 n. For example, when the periphery of the lower edge display portion 22n is brown, it is preferable to make the lower edge display portion 22n brownish or blackish.

Moreover, when the pattern which consists of unevenness | corrugations is formed in the top plate 20a, a convex part can be colored by the color different from the flat part 25, and designability can be improved. In such a case, more efficient work can be performed by simultaneously performing the same printing on the edge display unit 22, the horizontal direction display unit 23, and the auxiliary display unit 24.

Furthermore, when forming the pattern which consists of unevenness in the top plate 20a and coloring the convex part of the pattern in a color different from the flat part 25 in which the pattern is not formed, the edge display part 22, the horizontal direction display part 23, and the auxiliary display By providing the periphery 24 (for example, in a region indicated by a dashed dotted line in FIG. 1) in the portion 24, the presence of the edge display portion 22, the lateral direction display portion 23, and the auxiliary display portion 24 can be further clarified.

It is preferable that the height position of the upper surface of the edge display portion 22, the lateral direction display portion 23, and the auxiliary display portion 24 be equal to the height position of the upper surface of the pattern formed on the top plate 20a. By equalizing the height positions of these upper surfaces, the edge display portion 22, the horizontal direction display portion 23, the auxiliary display portion 24, and the pattern can be formed more reliably and collectively. In addition, the edge display unit 22, the horizontal direction display unit 23, the auxiliary display unit 24, and the upper surface of the pattern can be colored collectively.

In addition, although the height (height position of the upper surface) of the edge display part 22, the horizontal direction display part 23, the auxiliary display part 24, and the side wall of a pattern may differ, respectively, 0.2 mm or more and 2.0 mm or less It is preferable to be within the range of

By setting the height of the side wall to 0.2 mm or more, good distinguishability of the edge display portion 22, the horizontal direction display portion 23, and the auxiliary display portion 24 can be secured. When the height of the side wall is less than 0.2 mm, when coloring the display portions and the convex portions of the pattern, there is a possibility that printing stains may occur around them.

When the height of the side wall exceeds 2.0 mm, a relatively large gap is generated in the heavy portion where the metal wall members 1 are stacked on one another, and there is a possibility that the wind pressure resistance performance and the water blocking performance may be reduced. Moreover, there is a possibility that the crack of the metal plate itself which comprises the surface base material 2, and the crack of the plating layer or coating film provided in the surface may generate | occur | produce. Such cracking reduces the corrosion resistance of the metal wall material 1.

Next, FIG. 5 is a plan view showing a wall cutting structure using the metal wall material 1 of FIG. 1, and FIG. 6 is a side view showing two metal wall materials overlapping each other in FIG. As shown in FIG. 5, the metal wall material 1 of FIG. 1 arranges a plurality of metal wall materials 1 side by side on the wall foundation while abuts each other in the lateral direction 6 parallel to the eaves of the building. . Each metal wall material 1 is disposed on the wall base so that the longitudinal direction is along the lateral direction 6 and the short direction is along the vertical direction 5 of the wall. At this time, by aligning the side edge display portions 22s of the metal wall members 1 with each other, the alignment of the metal wall members 1 in the vertical direction 5 is performed. After the metal wall material 1 is disposed on the wall base, a binding member 8 such as a screw or a nail is driven into the metal wall material 1 to fix the binding member 8 to the wall base.

In addition, the lower end of the upper (upper in FIG. 5) metal wall 1 (11) on the upper end of the lower (lower in FIG. 5) metal wall 1 (10) in the vertical direction 5 Each metal wall material 1 is arranged on the wall base while overlapping the parts. At this time, the lower edge display portion 22n of the upper metal wall material 1 (11) is aligned with the butted side end of the lower metal wall material 1 (10), and the side edge of the upper metal wall material 1 (11) To the upper edge display 22m of the lower metal wall 1 (10) and the side edge display 22s of the upper metal wall 1 (11) on the ridge of the lower metal wall 1 (10) Aligning the upper metal wall material 1 (11) to the lower metal wall material 1 (10) is performed by aligning the end.

Further, as described above, when the upper edge display portion 22m or the lower edge display portion 22n is not used or when the upper edge display portion 22m or the lower edge display portion 22n can not be used for alignment due to cutting or the like, the horizontal direction display portion 23 The alignment can be performed in the same manner as described above using either the upper edge display 22m or the lower edge display 22n. In this case, the lower end of the horizontal display portion 23 of the metal wall material 1 (10) is aligned with the lower edge of the metal wall material 1 (11). Even if it is a part of metal wall material 1 (11) which can not use either upper edge display part 22m and lower edge display part 22n, it piles up along with horizontal direction display part 23 of metal wall material 1 (10). be able to.

Next, an example is given. The inventor made a trial manufacture of the metal wall material 1 as a test material under the following conditions.

As the front substrate 2, 0.3 mm of coated hot-dip Zn-55% Al plated steel plate was used. On the top plate 20a, a concavo-convex pattern was projected and processed by a press machine. The flow pattern shown in FIG. 4 is employed as the uneven pattern, and the height of the uneven pattern relative to the flat portion 25 where the uneven pattern is not formed is 0.3 mm.

As the edge display portion 22, a pair of side edge display portions 22s are provided on both edge portions of the top plate 20a in the lateral direction 1L, and the lateral direction display portion 23 and the auxiliary display portion 24 are provided on the top plate 20a. Further, a lower edge display portion 22n is provided below the top plate 20a, and an upper edge display portion 22m is provided above the top plate 20a. The lower edge display portion 22n and the upper edge display portion 22m are disposed at the center position of the top plate 20a in the lateral direction 1L.

The side edge display portion 22s and the upper edge display portion 22m are formed to be an equilateral triangle having a side of 10 mm when viewed in a plan view, and the corner portion is disposed outward of the edge portion of the top plate 20a.

Lower edge display unit 22n was the horizontal direction extending a width W _n and 5mm in the vertical direction extending a width W _nm an isosceles triangle to 10 mm.

A central display portion 23c disposed at the center of the top plate 20a in the lateral direction 1L and a pair of intermediate display portions 23i disposed between the side display portions 23s and the central display portion 23c are provided. The side display unit 23s, the center display unit 23c, and the intermediate display unit 23i are configured by three projections spaced apart in the lateral direction 1L.

The lower edge display portion 22, the plurality of lateral direction display portions 23 and the auxiliary display portion 24 disposed on the top plate 20 a are formed by the overhanging process with a press simultaneously with the flow pattern of the unevenness. The forming height (height of the side wall of each display portion) of the lower edge display portion 22, the plurality of lateral direction display portions 23 and the auxiliary display portion 24 with respect to the flat portion 25 where the pattern is not formed is 0.1 to 2.1 mm In the range of

Printing (coloring) on the top plate 20a was performed by a flexographic printing method using a printing machine manufactured by Neurong Corporation. As the ink, black ink of silicone acrylic resin type was used. After printing the ink with a urethane roll, it was dried at 70 ° C. for 5 minutes. The film thickness of the ink in the convex part of the edge display part 22 and several horizontal direction display parts 23 was 6 micrometers after drying. The ink film thickness was adjusted according to the hardness of the roll, the amount of applied ink, and the printing conditions such as the adjustment of the gap between the roll and the printing substrate.

After processing and printing the front substrate 2 to a predetermined wall material thickness and shape, the back substrate 3 is disposed on the back side of the front substrate 2 so as to close the opening of the main body 20, and is commercially available The foamed resin was injected into the space between the main body portion 20 of the front substrate 2 and the back substrate 3 by a high pressure injector. A 0.2 mm glass fiber paper was used as the back substrate 3. As the core 4, a two-component mixed foam resin was used. The mixing ratio of the polyol component and the nurate component was 1: 1 by weight. The resin foam is kept for 2 minutes in a mold whose temperature is adjusted to 70 ° C by warm water circulation, then the wall material is taken out from the mold and allowed to stand at room temperature 20 ° C for 5 minutes to complete foaming of the resin. The

The present inventors used (1) the evaluation of identifiability, (2) the evaluation of printability on convex portions (adhesion of printing stains on flat portions) using the above-described test material, and (3) of the wall material An evaluation was made of the degree of occurrence of the gap. The results are shown in the following table.

(1) Evaluation of Distinctiveness The wall material 1 was installed outdoors so that the vertical direction was vertical, and the wall material 1 was visually evaluated from a 45 ° angle. In addition, the evaluation selected the day of fine weather and performed, and evaluated it by the following criteria.
:: extremely easily identifiable :: easily identifiable :: identifiable ×: not identifiable

As shown in Table 1, when the forming height of each of the

display portions

22, 23, 24 is less than 0.2 mm, identification of each of the

display portions

22, 23, 24 is difficult. Therefore, it was confirmed that the molding height of each of the

display portions

22, 23, 24 is preferably 0.2 mm or more from the viewpoint of the distinguishability of each of the

display portions

22, 23, 24.

(2) Evaluation of Printability on Convex Portions (Adhesive Print Contamination on Flat Portions) Contamination associated with ink adhesion on the flat portions 25 was evaluated based on the following criteria.
○: no ink adhered to flat part Δ: slight ink adhered to flat part ×: ink adhered to flat part

When the forming height of each of the

display portions

22, 23, 24 is less than 0.2 mm, the ink adheres to the flat portion 25 and stains occur. From this, it was also confirmed that the molding height of each of the

display portions

22, 23, 24 is preferably 0.2 mm or more from the viewpoint of printing stains.
