[Industrial applications]

 The present invention relates to a metal siding material that is easy to stack and pack and does not scratch the surface even when transported by truck.

[0002]

[Prior art]

 Conventionally, various metal siding materials have been widely used for the interior and exterior of a house, and the general metal siding materials are as shown in FIGS. 4 and 5. In the case of FIG. 4, the widthwise both sides of the coated metal strip are bent to the back side along the longitudinal direction to form a trough having side walls 2 and 2a on both sides of the flat portion 1, and then the base portion of one side wall 2 is formed. The female fitting portion 3 is formed along the longitudinal direction by bending the side so as to be recessed inward from the flat portion 1, and the base side of the other side wall 2a is projected outward from the flat portion 1. Since the female fitting portion 3 and the male fitting portion 4 which can be fitted are similarly formed along the longitudinal direction, the tip end side of the side wall 2 is inside and the tip end side of the side wall 2a is outside. It is folded back to form the folded portion 5 on the female fitting portion side and the folded portion 6 on the male fitting portion side. These folded-back portions 5 and 6 are substantially parallel to the flat portion 1, and the folded-back portion 5 on the female fitting portion side is slightly separated from the surface of the flat portion 1 so that Is filled with urethane or phenol foam resin 7 up to the height of both, and the surface is covered with a backing material 8.

Further, in the case of FIG. 5, as in the case of FIG. 4, both sides in the width direction of the coated metal strip are bent to the back side along the longitudinal direction, and side walls 2 and 2 a are provided on both sides of the flat portion 1. It is a gutter, but the bases of both side walls 2 and 2a should be flat, and the tips should be bent so that they are both recessed inside the flat 1 so that they are approximately parallel to the flat 1. As shown in FIG. 4, the inside of the gutter-shaped body is folded up to the height of both the folded portions 10, 10a in the same manner as in the case of FIG. 4 and is folded back to the outside to form the insertion grooves 9, 9a and the folded portions 10, 10a. Resin 7 is filled and the surface is covered with a backing material 8.

These metal siding materials are continuously manufactured by a method in which the foamed resin and the backing material 8 are supplied from the inside while molding by roll forming with the front side of the coated metal strip facing down. However, since it is difficult to wind up the product, it is cut into a specified length at the same time as it is manufactured, and the specified number (for example, 11) is stacked in a cardboard box, and then packed in a box. I used to pack the cardboard boxes with a plastic band. However, if the flat parts 1 on the front side are piled up so that all of the flat parts 1 on the front side face up during packaging, in the case of FIG. 4, the folded part 5 on the female fitting part side and the folded part 6 on the male fitting part side are arranged. In addition, in the case of FIG. 5, since the folded-back portions 10 and 10a are both located on the flat portion 1, the coated surface of the flat portion 1 is scratched due to load collapse during transportation by truck, and the appearance and corrosion resistance are deteriorated. It will be damaged. This tendency was very strong on the coated surface, especially when the coated metal strip was embossed.

Therefore, when packing the boxes, the front sides are faced to each other and a protective paper is inserted between them to prevent the occurrence of scratches. However, the use of the protective paper is expensive and the metal siding material is long. If so, it was difficult to insert. Moreover, since the metal siding material is always cut with the front side facing down, it was necessary for an operator to invert every other sheet to match the front sides. In particular, when the metal siding material is long, it takes heavy labor, so that two workers cannot continue for a long time, which requires replacement personnel. In addition, since a large amount of unnecessary protective paper is generated at the construction site, it takes time and money to dispose of it, industrial waste increases, and resources are wasted.

[0006]

[Problems to be solved by the device]

 The present invention provides a metal siding material that solves these problems.

[0007]

[Means for Solving the Problems]

 In the present invention, a tape material is attached to the folded portion.

[0008]

[Action]

 In the case of the metal siding material shown in FIG. 4, since the folded portion 5 on the female fitting portion side is folded back inward, it is always located on the back side of the flat portion 1 and stacked so that the front side and the back side are in contact with each other. In this case, the flat portion 1 is contacted. On the other hand, since the folded-back portion 6 on the male fitting portion side is folded back to the outside, when the metal siding material is stacked depending on whether the folding-back starting point is on the back side of the flat portion 1, Contact or not. That is, when the folding start point is on the back side of the flat portion 1, the folding portion 6 is located on the back side of the flat portion 1, and when stacked, contacts the flat portion 1. However, when the folding start point is outside the back side of the flat portion 1, the folding portion 6 is located outside the flat portion 1 and therefore does not come into contact with the flat portion 1 even if metal siding materials are stacked. In the former case, tape material is attached to both of the female fitting portion side and male fitting portion side folding portions 5 and 6, and in the latter case, only to the female fitting portion side folding portion 5. Attach the tape material.

In the case of the metal siding material shown in FIG. 5, both of the folded-back portions 10 and 10a are inside the flat portion 1. Therefore, when they are stacked so that the front side and the back side are in contact with each other, both folded-back portions 10 and 10a are stacked. Contacts the flat part 1. For this reason, the tape material is attached to both of the folded portions 10, 10a.

When a tape material is attached to the folded-back portions 5, 6, 10, 10a, the surface of the folded-back portion becomes smooth, so that even if it shifts in contact with the flat portion 1 of the metal siding material, the flat portion Does not scratch the painted surface of. Therefore, even if a load collapses during transportation, the appearance is not impaired and the corrosion resistance is not deteriorated. It is preferable to attach the tape material to the entire width of the folded portions 5, 6, 10, and 10a, but if the tape material is thick, if it is attached to a part, even if the metal siding materials are stacked, the flat portion will be formed. Since a gap is formed between the folded-back portion 5, the folded-back portions 5, 6, 10, 10a do not contact the flat portion 1.

If the tape material is pasted before cutting the metal siding material into a predetermined length, it is cut at the same time as the cutting of the metal siding material, so that it is not particularly necessary to cut the tape material. . The tape material may be a tape coated with a hot-melt or pressure-sensitive adhesive, or a tape coated with an adhesive, but a tape coated with an adhesive or an adhesive is special for sticking. Excellent workability because no device is required. The material of the tape is not limited, and may be paper, cloth, or plastic film.

【Example】

 Example 1 FIG. 1 shows a first example of the metal siding material of the present invention, which has the same shape as the conventional one shown in FIG. 4, but the coated metal strip of the material is embossed. The colored zinc iron plate is used. Further, urethane resin is used as the foamed resin 7, and laminated paper with aluminum foil is used as the backing material 8. The folding portion 6 on the male fitting portion side has the folding start point located on the back side of the flat portion 1, the width of the folding portion 6 on the male fitting portion side is 25 mm, and the commercially available adhesive paper tape with a width of 30 mm is used on the entire surface. I have pasted the puppy 11. Further, the folded-back portion 5 has a width of 20 mm, and a similar adhesive paper tape 9 is attached to the entire surface. The working width of this metal siding material is 260 mm, the length is 3048 mm, and the unit weight is 0.782 kg / m.

Example 2 In the metal siding material of Example 1, the folding start point of the folding section 6 on the male fitting section side is located outside the back side of the flat section 1 as shown in FIG. No adhesive paper tape 11 was attached to the.

Embodiment 3 FIG. 3 shows a third embodiment of the metal siding material of the present invention, which has the same shape as the conventional one shown in FIG. 5, but is embossed as a coated metal strip of the material. A colored zinc iron plate that has been processed is used. Further, a phenol resin is used as the foamed resin 7, and a laminated paper with an aluminum foil is used as the backing 8. The folding back portions 10 and 10a have a folding back starting point located on the back side of the flat portion 1 and the width of the folding back portion 10 is 13 mm. However, the width of the folding back portion 10a is as wide as 17 mm, and a commercially available width 3 A 0 mm pressure-sensitive adhesive-coated paper tape 12 is attached. The working width of this metal siding material is 260 mm, the length is 3048 mm, and the unit weight is 0.408 kg / m.

Eleven metal siding materials of Examples 1, 2 and 3 were packed in a dumbbell box so that the front side was all up, and the outside of the box was bound with a polypropylene band by an automatic binding machine to obtain other products. Using a truck-based transportation service, we made a round trip of 100 km each way. The total weight after packaging was about 26 kg in the case of Examples 1 and 2, and about 14 kg in the case of Example 3, but neither metal siding material was scratched at all.

[0016]

[Effect of device]

 As described above, even if the metal siding material of the present invention is packed and transported so that the front side of the metal siding material is in contact with the back side without inserting the protective paper between the metal siding materials, the painted surface is not scratched. There is no mark. Therefore, the work of inserting the protective paper between the metal siding materials and reversing the metal siding material to align the front sides with each other, which is conventionally performed, is not necessary, and the work is greatly reduced. In addition, it is not necessary to insert protective paper, and the metal siding material can be stacked and boxed while it is cut, so if the tape material is attached automatically, the packaging can be automated. In addition, no unnecessary protective paper is generated at the construction site, which helps reduce industrial waste and protect resources.
