Description

TECHNICAL FIELD The present invention relates to a wall material formed by roll-molding a metal plate.

2. Description of the Related Art Roll forming metal plate wall materials are usually formed by rolling a long metal plate into a desired shape while transferring it in the length direction. At the time of this processing, only a force that forms a bent line in the length direction, that is, a force in a direction orthogonal to the length direction is applied to the metal plate, and a force in the length direction is not applied. For this reason, elongation deformation occurs in the width direction due to processing, and as a result, contraction deformation occurs as a whole in the length direction. Moreover, since the side end portion has a small amount of processing and scarcely undergoes shrinkage deformation, the side length becomes excessive, resulting in a rough shape, that is, a wavy shape. This rampage not only impairs aesthetics and reduces the commercial value, but also makes it difficult to nail the wall material onto the base material and to fit adjacent wall materials to each other.

Therefore, the present invention was devised for the purpose of eliminating this rampage.

Means for Solving the Problem That is, according to the present invention, at a side end portion which is in contact with a wall surface or which is fitted with another wall material, a bending line extends in the width direction from the edge, and is bent in a continuous wavy shape in the length direction. The roll-formed metal plate wall material is characterized in that a side portion is formed to prevent the side edge from being rough.

Function Since the bent portion of the present invention is such that the side end portion is wavy and deformed so as to be longer than the other portions of the metal plate, the above-described rampage can be absorbed and prevented. Since this bent portion can be processed by sandwiching the side end portion of the metal plate with a roll whose peripheral edge has an uneven shape, this processing can be easily incorporated during roll forming processing.

Embodiments Embodiments illustrating the present invention will be specifically described below.

This wall material 1 is formed by roll-forming a metal plate such as an iron plate,
It is for horizontal lining with the length direction horizontal. When the wall material 1 is used, a concave fitting portion 2 is formed at a side end that is a lower end when used, and a concave fitting portion 2 that is a concave shape is formed toward the direction, and a convex fit that is convex upward is formed near a side end that is an upper end. A joint 3 is formed. Further, the side end portion 4 connected to the convex fitting portion 3
Are extended upward along the wall base material 5, and the bent portions 6 are formed in the width direction, that is, the vertical direction, and the bent portions 6 that are wavy in the length direction, that is, the horizontal direction are formed.
The bent portion 6 is formed to have a width that extends over the entire width of the side end portion 4.

Since the wall member 1 has the bent portion 6 as described above, the side end portion 4 does not have the turbulence as in the conventional case. For this reason,
As shown in the figure, in the work of sequentially attaching the wall material 1 from the lower side, the wall material 1 to which the concave fitting portion 2 at the lower end has already been attached
After being fitted to the convex fitting portion 3 of the above, when the nail 7 is attached to the side end portion 4 of the upper end to attach it to the base material 6, since the side end portion 4 does not have any rough movement, the attachment is easy and accurate. It becomes possible to work.

In this example, the bent portion 6 contacts the base material 5 and the side end portion 4
Since the bends are designed to extend over the entire width of
The bent line of the bent portion 6 has a reinforcing effect against a force for separating the wall material 1 from the base material 5.

In this example, a bent portion is provided only on the side end portion of the upper end, and in the shape of this example, only this bent portion is sufficient,
Depending on the shape of the wall material, bent portions may be provided at the side end portions or both side end portions of the lower end.

Further, in this example, the bent portion is formed to have a width that extends over the entire width of the side end portion, but a part of the width may be left. However, since the edge part is the part where the rampage is most visible, and the rampage of this part makes the installation work extremely difficult, this bent part shall be extended from the edge to prevent this rampage. There must be.

It should be noted that if the bent portion is intermittent and there is a flat portion in the middle, it will rage, so it is necessary to form this bent portion continuously.

Advantageous Effects of Invention The wall material of the present invention is formed by roll-molding a metal plate as described above, but has a continuous wavy shape that is in contact with a wall surface or that is fitted to another wall material. Since it has a bent portion, the side edges do not run out and the mounting work is easy,
It is aesthetically pleasing and can also be reinforced.
