Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel wallpaper which can be stretched as it is without any smooth repair even on a ground base having uneven surface.

[0002]

2. Description of the Related Art In recent years, construction methods have advanced, and most of building materials have been produced in factories, and are currently manufactured with extremely high precision. However, it cannot be applied to the walls of houses constructed using such high-precision building materials (1
0 ') occurs. In particular, the walls are conspicuous, and the uneven (10 ') portions appear to rise when the light strikes them at an angle.

[0003] When such unevenness (10 ') appears on the wall, it significantly reduces the value of the building, and the wallpaper attaching process at the final stage tends to be performed very carefully. That is, first, the uneven (10 ') portion is filled with putty, and at the same time, smooth repair is performed so that the shadow does not appear clearly on the wall due to oblique light. Next, paste the glue (9 ') evenly on the back side of the wallpaper (A') and evenly attach it to the wall base (8 ') while matching the pattern, and finally, the overlapping part of the wallpaper (A'). And cut with a cutter so that it will be in a correctly butted state.

In the pasting work of such wallpaper (A '),
A large amount of work time is required for smoothing and repairing the groundwork. In other words, if the groundwork repair work can be simplified, the wallpaper
The work efficiency of (A ') k sticking work will be greatly improved.
However, as the conventional wallpaper (A ') was only the adhesive (9') applied to the back surface of the cross sheet (4 ') as shown in Fig. 5, the wall base (8') as shown in Fig. 6 was used. If there is a rough land (10 '),
The wallpaper (A ') is stuck along the uneven (10'),
There was a problem that (10 ') floated up.
Therefore, the background repair work could not be omitted with the conventional wallpaper (A ').

Further, when the wallpaper (A ') is attached to the wall, conventionally, the edges of the wallpaper (A') are overlapped and attached to the wall, and then the overlapped portion is straightened with a ruler. A method has been adopted in which cutting is performed to form an accurate overlapping end portion, and finally, the abutting portion is attached to the wall base with glue. Although this method enables a beautiful butt sticking, there is a problem that after a lapse of time, the butt ends are peeled off from the wall base and gradually come up and become very ugly.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art. First, in the wallpaper itself, firstly, a wall base having unevenness is provided without performing the base repair work. Its purpose is to develop a wallpaper that can be directly attached, and secondly, it is to develop a wallpaper that does not cause the edges to curl up. In addition, the purpose of the wallpaper sticking method is to develop a sticking method in which the butt ends of the wallpaper do not turn up over time.

[0007]

Means for Solving the Problems In order to achieve the above object, the present invention provides a "core material sheet (1) having a small shrinkage ratio when the material is elastic and dries from a wet state, and the core material sheet (1 One of the wallpaper base sheet (B) and the wallpaper base sheet (B) composed of a shrinkable sheet (2) (3) that is affixed with dots on both sides and contracts greatly when dried from a wet state It is attached to the surface of and is composed of a cross sheet (4) ”. As a result, the wall foundation (8) with the unevenness (10) can be stretched as it is without any smooth repair.

Further, the second aspect is characterized in that "the attachment points (5) and (6) of the front and back shrinkable sheets (2) and (3) are displaced from each other". As a result, when the wallpaper (A) is pasted, the dots of the wallpaper base sheet (B) will not appear on the cloth surface,
A more beautiful cloth can be pasted.

In claim 3, "Wallpaper base sheet (B),
A cross sheet (4) attached to the wallpaper base sheet (B), and a difficult-to-cut tape (11) sandwiched between one end of the wallpaper base sheet (B) and the cross sheet (4). It is composed of ”. As a result, when the cross sheets (4) are overlapped and pasted together, since the difficult-to-cut tape (11) exists under the overlapped portions of the cross sheet (4), the overlapped portions of the cross sheet (4) Cross sheet without any consideration when cutting along the cutting line (12)
Even if the (4) is cut, the wallpaper base sheet (B) is not cut, and the difficult-to-cut sheet (11) is peeled off (or stuck as it is), but the cross sheet (4) is butted. It can be attached to the wallpaper base sheet (B) whose edges are not cut. As a result, the cross sheet (4) is integrally attached to the uncut wallpaper base sheet (B), and even if a long time has elapsed, the phenomenon of winding up due to peeling of the end of the cross sheet (4) is prevented. To be done.

According to a fourth aspect of the present invention, "any one of the wallpaper base sheet (B), the cross sheet (4) which is attached to the wallpaper base sheet (B) while being shifted, and the portion which is offset and overlapped In the above, it is composed of a wallpaper base sheet (B) and a cross sheet (4) and a difficult-to-cut tape (11). As a result, the rolling-up phenomenon due to the peeling of the end portion of the cross sheet (4) is prevented even after a long time has passed as described above.

[0011] Claim 5 states that "a wallpaper base sheet (B), a cross sheet (4) attached to the wallpaper base sheet (B), or a wallpaper base sheet (B) or a cross sheet (4). A wallpaper (A) is composed of the difficult-to-cut tape (11) sandwiched between one ends, and the cross sheet (4) is overlapped and the wallpaper base sheet (B) and the cross sheet (4) are overlapped. Position the difficult-to-cut tape (11) between the mating parts and attach it to the wall base (8), and then cut the overlapping part of the cross sheet (4) on the hard-to-cut sheet (11). Then, after that, remove the surplus part (13) of the cut cloth sheet (4) and attach the abutting part of the cross sheet (4) formed by cutting to the wallpaper base sheet (B). ' Characterize. As a result, when the wallpaper (A) of claim 3 is attached to the wall base (8),
As described above, the rolling-up phenomenon due to the peeling of the end portion of the cross sheet (4) is prevented even after a long time has passed. It should be noted that if the thickness of the difficult-to-cut tape (11) is large or if there is a problem with the adhesiveness, it is desirable to remove it, but if it is not, then it will adhere to the bottom of the cross sheet (4). May be.

According to a sixth aspect of the present invention, "any one of the wallpaper base sheet (B), the cross sheet (4) which is affixed to the wallpaper base sheet (B) in a shifted manner, and the shifted and overlapped portion In the wallpaper base sheet (B) and the cross sheet (4), the wallpaper (A) is composed of the difficult-to-cut tape (11) sandwiched between the cross sheet (4) and the wallpaper base sheet. Position the hard-to-cut tape (11) between the (B) and the overlapping portion of the cross sheet (4) and attach the tape to the wall (12), and then attach the overlapping portion of the cross sheet (4). Cut on the difficult-to-cut sheet (11), and then remove the surplus part (13) of the cut cross sheet (4), and cut the abutted part of the cross sheet (4) to form the wallpaper base sheet. It is attached to (B) ”. As a result, when the wallpaper (A) of claim 4 is adhered to the wall substrate (8), the rolling-up phenomenon due to the peeling of the end portion of the cross sheet (4) is prevented even after a long time as described above. .

[0013]

The method of the present invention will be described below with reference to the illustrated embodiments. The wallpaper (A) according to the present invention is composed of a cross sheet (4) as a surface material and a wallpaper base sheet (B). The cloth sheet (4) is usually used, and the surface thereof is appropriately printed with a solid color, various patterns, and uneven patterns.

The wallpaper base sheet (B) is composed of three layers, and the middle layer is a core material sheet (1) having a rigidity, and the core material sheet (1)
The shrinkable sheets (2) and (3) are attached on both sides of the sheet by dots. Western paper or aluminum foil is used as the elastic core sheet (1), and Japanese paper is used as the shrinkable sheets (2) and (3). Core sheet (1) and shrinkable sheet (2)
With the method of sticking with (3), instead of sticking all over, sticking will be done as shown in the figure. The point is not limited to a circle, and an appropriate shape such as “x” or “+” is adopted. Core material sheet at points
A water-resistant adhesive is used as the adhesive for attaching the shrinkable sheets (2) and (3) to both surfaces of (1).

Further, the core sheet (1) and the shrinkable sheets (2) (3)
For the sticking with, the sticking may be made at the same position, but it is preferable that the sticking points (5) and (6) of the front and back shrinkable sheets (2) and (3) are displaced from each other. . As a result, the gap layer (7) is formed between the core sheet (1) and the shrinkable sheets (2) and (3). The above cross sheet (4) is entirely attached to the front surface side of the wallpaper base sheet (B), and the adhesive (9) is applied to the back surface side.

Further, the wallpaper (A) has a structure in which the wallpaper base sheet (B) and the cross sheet (4) are entirely overlapped as shown in FIG. 5, and the wallpaper base sheet (B) and the cross sheet are
A structure in which the difficult-to-cut tape (11) is sandwiched between either ends of (4) and a cross sheet (4) for the wallpaper base sheet (B) as shown in FIG. ) Are stuck together, and the hard-to-cut tape (11) is sandwiched between the wallpaper base sheet (B) and the cross sheet (4) at either one of the shifted and overlapped parts, etc. Can be considered. In addition, the edge structure of the wallpaper (A) is
Although (B) may have a three-layer structure as shown in FIG. 1, a one-layer structure as in the conventional example may also be applied. Examples of the hard-to-cut tape (11) include thick paper, thick metal foil, woven fabric, non-woven fabric and the like.

Then, the wallpaper (A) is pasted on the wall base (8) having the unevenness (10). First, the glue ( Apply 9). The water content of the applied glue (9) wets the applied Japanese paper to make it soft and elongated. At the same time, the water content of the glue (9) is the middle layer core sheet.
It passes through (1) and moves to the shrinkable sheets (2) and (3) on the surface side, wets it, and similarly becomes soft and stretches.

On the other hand, the elastic core sheet (1) of the middle layer is hydrated and becomes soft to some extent, but the strength of the waist remains to some extent and does not extend so much. Therefore, the core sheet (1)
The shrinkable sheets (2) and (3) on both sides with respect to are in a wet and swollen state. As described above, the presence of the core sheet (1) allows the entire wallpaper (A) to have a certain degree of elasticity even when the back surface of the wallpaper (A) is glued, and the wallpaper (A) is easily attached.

While gluing in this way, the wall substrate
Clean (8) and attach it to the wall base (8) in order from the wallpaper (A) that has been glued. Since the shrinkable sheets (2) and (3) are swollen in a water-containing state as described above when they are attached, the shrinkable sheet (3) on the wall base (8) side is well adapted to the unevenness (10) of the wall. Glued in.

On the other hand, the core material sheet (1) has a certain amount of voids (7) because it is somewhat elastic and the shrinkable sheet (3) on the wall base (8) side is point-bonded. , The uneven (10) part will be bonded in a slightly floating state.

Further, the front side shrinkable sheet (2) is arranged along the core material sheet (1) in a swollen state, and the cross sheet (4) is further positioned on it. In this way, the wallpaper (A) is pasted on the wall foundation (8) one after another, and the overlapping parts of the edges are cut to bring them into a butt state, but with the passage of time, the wallpaper (A) will gradually change. Go dry.

As it dries, the shrinkable sheets (2) and (3) gradually shrink and apply a uniform tension to the entire wallpaper (A) attached. Here, the side shrinkable sheet (3) of the wall base (8) is the wall base
Entirely adhered along (8), but the core sheet (1) is the wall base
Wall base (8) due to point adhesion to (8) side sheet (3)
Not bound by the side shrinkable sheet (3). On the other hand, the core sheet (1) can be sufficiently tensioned by the shrinkage of the front side shrinkable sheet (2), so it has almost nothing to do with the unsteady surface (10).
It will be stretched to (8). Since the front cross sheet (4) is also entirely attached to the front side shrinkable sheet (2), it receives the tension of the front side shrinkable sheet (2) and has almost nothing to do with the unsteady surface (10). It will be stretched to the groundwork (8). Due to the above, the wall base (8) is not subjected to smooth repair work, and the wallpaper (A) is used as it is.
Even if you stick it, the unevenness (10) does not appear on the wallpaper (A).

The core sheet (1) and the shrinkable sheets on both sides
(2) When the point adhesive parts of (3) are at the same position, the adhesive part of the shrinkable sheet (3) on the wall base (8) side during shrinkage passes through the shrinkable sheet (2) on the front side as it is. It may appear on the surface of the cross sheet (4), which may not be preferable.

Therefore, as shown in FIG. 1, the point adhesive positions are displaced from each other so that the shrinkage sheet (3) on the side of the wall substrate (8) at the time of shrinkage is directly attached to the shrinkable sheet (2) on the surface side. ), It does not appear on the surface of the cross sheet (4), and more beautiful wallpaper (A) can be attached. It should be noted that the core material sheet (1) and the shrinkable sheets (2) and (3) on both sides are not shown because they can be easily inferred from FIG.

In this example, Japanese paper was used as the shrinkable sheets (2) and (3), and western paper was used as the core sheet (1).
Of course, it is not limited to this, and for example, aluminum foil may be used as the core material. In this case, since the aluminum foil itself has no water permeability, moisture does not migrate to the shrinkable sheet (2) on the surface side, and therefore it is necessary to form a large number of pinholes for moisture migration. When not doing so, the cross sheet (4) side is made water-permeable so that the shrinkable sheet (2) on the surface side absorbs water, and the moisture from the surface side shrinks the sheet on the surface side ( Try to move to 2).

The shrinkable sheets (2) and (3) are not limited to Japanese paper, and any sheet that swells and expands when it contains water and shrinks when it is dried can be used.

Next, the wallpaper (A) shown in FIG. 6 will be described as a typical example of edge processing. As shown in FIG. 7, the wallpaper base sheets (B) are superposed on each other and the wallpaper (A) is attached to the wall base (8). In this case, since the wallpaper base sheet (B) and the cross sheet (4) are detached and adhered, the cross sheet (4) is exactly overlapped on the lower wallpaper base sheet (B) Become. Furthermore, the difficult-to-cut tape (11) is placed between the wallpaper base sheet (B) and the overlapping portion of the cross sheet (4), and the overlapping portion of the cross sheet (4) is difficult to cut. Cut on the sheet (11), after that, remove the surplus portion (13) of the cut cross sheet (4) and the difficult-to-cut tape (11), the butt portion of the cross sheet formed by cutting. Attach it to the wallpaper base sheet (B). Cut the line (1
Shown in 2). If the difficult-to-cut tape (11) is sufficiently thin and has excellent adhesiveness, it is not necessary to peel it off, and the cross-sheet (4) may be attached on the difficult-to-cut tape (11).

As a result, the cross sheet (4) is adhered to the uncut wallpaper base sheet (B) integrally, and even after a long time has elapsed, the cross sheet (4) is rolled up by peeling off the end portion of the cross sheet (4). The phenomenon will be prevented. This point is the same for the wallpaper (A) of FIGS. 1 and 4, and thus the description thereof will be omitted.

[Effect] The wallpaper according to the present invention can be applied to a core sheet having a low shrinkage ratio when it is elastic and has a small shrinkage when dried from a wet state, and when it is attached to both sides of the core sheet by dots and dried from a wet state. Since it is composed of a wallpaper base sheet composed of a shrinkable sheet that greatly shrinks and a cross sheet attached to one surface of the wallpaper base sheet, the shrinkable sheet on the wall base side prevents unevenness of the wall. It is well-adhered and adhered, and the shrinkable sheet on the front side shrinks greatly when it dries, giving tension to the entire wallpaper and pulling up the entire wallpaper.

Further, since both are only point-bonded, they are bonded to the shrinkable sheet on the wall base side in a state where there is a certain amount of voids, and the shrinkable sheet on the wall base side is attached to the wall base. The core material sheet is adhered along the entire surface, but is not entirely restrained with respect to the wall base side sheet, and alleviates the appearance of inferiority on the surface side. Similarly, the surface-side shrinkable sheet is not entirely restrained by the core material sheet, and alleviates the appearance of unevenness on the surface side. In addition to this, the shrinkage of the front-side shrinkable sheet gives sufficient tension to the core sheet, so that the wallpaper is stretched on the wall foundation almost regardless of the unevenness. As a result, there is an advantage that even if the wallpaper is applied as it is without performing the smooth repair work on the wall foundation, the unevenness does not appear on the wallpaper.

Further, in the second aspect, since the sticking points of the front and back shrinkable sheets are displaced from each other, the adhesive portion of the shrinkable sheet on the wall base side at the time of shrinkage is directly passed through the shrinkable sheet on the front side. It does not appear on the surface of the cloth sheet, and has the advantage that more beautiful wallpaper adhesion can be performed.

In the third aspect, since the difficult-to-cut tape is sandwiched between either one of the ends of the wallpaper base sheet and the cross sheet, when the cross sheets are superposed and attached to each other, the bottom part of the cross sheet is overlapped. Since the difficult-to-cut tape is present in the sheet, when cutting the overlapping portion of the cross sheet, the wallpaper base sheet is not cut. As a result, the abutting end of the cross sheet can be attached to the uncut wallpaper base sheet, and the winding phenomenon due to peeling of the end of the cross sheet can be prevented even after a long time has passed. is there.

According to a fourth aspect of the present invention, the cloth sheet is attached to the wallpaper of the third aspect by shifting the cross sheet with respect to the wallpaper base sheet. As a result, it is possible to more easily perform the work of sticking to the wall base.

[0034] Claims 5 and 6 are an example of a method of attaching wallpaper, in which the cross sheet is superposed and the difficult-to-cut tape is positioned between the wallpaper base sheet and the superposed part of the cross sheet to form a wall. Stick it on the base, then cut the overlapping part of the cross sheet on the difficult-to-cut sheet, and then remove the excess part of the cut cross sheet, and remove the butt part of the cross sheet formed by cutting. As a result, when the wallpaper of claim 3 is applied to a wall base material, the abutting end of the cross sheet is applied to an uncut wallpaper base sheet as described above. Even after a long period of time has elapsed, the rolling-up phenomenon due to the peeling of the end portion of the cross sheet is prevented.
