In this case, semicircular cutouts 4 are provided on both sides thereof in a staggered manner in the longitudinal direction. Then, it is desirable that the notch 4 is formed in the center of the tape width. When the double-sided adhesive tape 2 is used for interior decoration, as shown in FIG. 12, the adhesive A is applied to the notches 4 of the tape 2 attached to the concrete surface, and if necessary, the tape 2 After the adhesive A is applied to the outside of both sides, the release paper 2b is peeled off and the decorative plate or the base plate is attached. In this embodiment, the adhesive A can be applied very easily by the notch 4 of the double-sided adhesive tape 2, and moreover, the side edges of the decorative plate or the base plate can be adhered, and one of the notches 4 is opened. Therefore, there is an advantage that the adhesive A in this portion easily dries.

In the second to fourth embodiments described above, the double-sided adhesive tape 2 in the form of a roll wound with the release paper 2b as the outside is cut into a predetermined length at the construction site for use. However, as another method, it is possible to use a strip-shaped member that is cut in advance to a predetermined length. However, in the case of such a strip-shaped one, it is necessary to attach release papers to both adhesive surfaces, respectively.

Although the four embodiments have been described above,
In the interior decoration method of the present invention, it is preferable to use a decorative board K as shown in FIGS. 13 and 14.

This decorative plate K has a decorative sheet 6 on the front side of a rectangular substrate 5, and a wedge-shaped kerf 7 parallel to the side and extending from the upper side to the lower side is formed on the back side of the substrate 5. Are provided near the sides of the. Further, the illustrated decorative plate K includes inclined end surfaces 8 formed on both the substrate 5 and the decorative sheet 6 by cutting so that the decorative sheet 6 side has an acute angle on the left and right sides.

The substrate 5 is made of a plaster board, and the raw material of the plaster is wrapped in paper on both sides, while the decorative sheet 6 is coated with vinyl chloride containing a foaming agent on the paper sheet. Then, the vinyl chloride is heat-foamed and then embossed to form an uneven pattern. Then, the decorative sheet 6 is attached to the front side of the substrate 5 with an adhesive to form a normal decorative board,
Next, the left and right sides are cut off so that the decorative sheet 6 side becomes an acute angle to form inclined end faces 8, and then the wedge-shaped kerf 7 is formed on the back side of the substrate 5 near the left and right sides. Board K has been created. The kerf 7 in this embodiment is formed to a depth that almost reaches the paper sheet of the gypsum board.

For example, the case of using the decorative board K in the interior decoration method described in the first embodiment will be described. The concrete surface is in a bad state and the flat plate member 1 tilts left and right as shown in FIG. Where the decorative sheets K are left and right, the left and right decorative plates K are bent with the kerf 7 as a boundary with the decorative sheets 6 connected to each other, and the side edges and the kerf 7
Since the narrow portion 9 between them is fixed along the surface of the flat plate member 1, no step is formed on the joint surface α. That is,
By pressing the narrow portions 9, 9 from the outside, the adhesive portion 1
0 is compressed so that the narrow groove 9 on the right side is slightly narrowed and the narrow groove portion 9 on the left side is bent so that the groove 7 is slightly widened, and each narrow portion 9 is bent. Since it follows the surface of, the step of the joint surface α is eliminated. Further, since the side edges of the decorative plate K are the inclined end faces 8, the decorative sheets 6 are pressed against each other without contact to each other without a gap, so that the joints between the decorative sheets 6 are hidden and inconspicuous.

Although not shown in the drawing, at the flat plate member 1 affixed to the concrete surface in a slightly overhanging state, each decorative plate K is bent so that the kerf 7 is slightly narrowed, and on the contrary, it is in a slightly retracted state. At the flat plate member 1 adhered to the concrete surface, each decorative plate K is bent so that the kerf 7 is slightly widened, so that both narrow width portions 9 are along the surface of the flat plate member 1, respectively. As a result, the step on the joint surface α is eliminated. Further, even if these flat plate members 1 are inclined, they are bent appropriately to eliminate the step.

As described above, by performing the interior coating method of the present invention using the decorative board K having the above-described structure, even if the flat plate member 1 or the double-sided pressure-sensitive adhesive tape 2 is not directly attached to the concrete surface, the makeup is improved. It is possible to prevent a step from being formed on the joint surface between the plates K.

Here, in the above decorative plate K, it is desirable that the position of the cut groove 7 should be as little as possible from the flat plate member 1 and the double-sided adhesive tape 2.
It is preferable that they are separated from the joint surface α between them as much as possible. Therefore, the distance between the kerf 7 and the side edge may be appropriately determined depending on the width of the flat plate member 1 or the double-sided adhesive tape 2 so as to satisfy such a condition.

When the flat plate member 1 is used, if the thickness of the adhesive F applied to one surface, that is, the surface on which the decorative plate K contacts, is thin, the decorative plate K is separated by the kerf 7. The groove 7 may not be bent in the narrowing direction. Therefore, in order to eliminate such a situation, when the thickness of the pressure-sensitive adhesive F applied to the front side of the flat plate member 1 is small, the right and left corners on the front side of the flat plate member 1 may be shaved appropriately.

In the decorative plate K shown in FIG. 16, the kerf 7 has a rectangular shape, and a foldable thickness is left at the bottom of the kerf 7. If the cut groove 7 is rectangular like the decorative plate K, and if the cut groove 7 is formed to a depth that almost reaches the decorative sheet 6, the decorative sheet 6 becomes slack when bent and stands out. Therefore, it is preferable to leave a slight thickness on the decorative sheet 6 side of the substrate 5 in this manner.

In the above decorative plate K, the slanted end faces 8 are formed on both sides thereof, but the end face shape serving as the joint face is arbitrary. For example, it may be a right-angled end face like a normal decorative plate. However, in this case, it is necessary to carefully perform the work so that no gap is created on the joint surface α. The substrate 5 is not limited to a plaster board, but may be formed of calcium silicate, gypsum slag board, plywood, or the like, and the decorative sheet 6 may use wallpaper, cloth, or the like.

Further, the direction of the kerf 7 is not always the same as that of the substrate 5.
It is not necessary to provide it at a right angle from the back side of the, and it may be provided in an obliquely inclined direction. Further, the depth of the kerf 7 is the decorative plate K.
It is necessary to form it so that it can be bent, but it may have an appropriate depth depending on the material of the substrate 5 and the shape of the kerf 7.

[0032]

Since the present invention is configured as described above, it has the following effects.

According to the first aspect of the present invention, a pressure sensitive adhesive is partially applied on both sides of the flat plate member, and an adhesive is applied on both sides, and one surface is a concrete surface and the other surface is a decorative board or Since it is fixed on the back side of the base plate, the interior can be done simply by attaching the flat plate member to the concrete surface and then attaching the decorative plate or the base plate on top of it, thus saving labor in interior work. In addition, since the plaster which has been kneaded with water as in the past is not used, molds do not occur on the wall surface after the interior decoration, and the wall surface can be kept clean.

In the interior decoration method according to the second to fourth aspects, the interior work can be performed more easily by using the double-sided adhesive tape.

According to a fifth aspect of the present invention, there is provided a decorative board having a decorative sheet on the front side of a rectangular substrate, wherein cut grooves parallel to the side edges and extending from the upper side to the lower side are provided on the left and right sides of the back side of the substrate. By using the decorative plates that are provided near each other, even if the flat plate member or the double-sided adhesive tape is not stuck straight because the concrete surface is bad, the decorative sheet is connected as a kerf. By bending, the narrow portion between the side edge and the kerf is in a state of being along the surface of the pillar member, and the step in the joint surface between the decorative plates can be eliminated.
