[0001]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall material structure applied to a unit house such as a prefabricated house, a construction method therefor, and a wall material used therefor.

[0003]

[0002]

[0004]

2. Description of the Related Art In a unit house such as a prefabricated house, a unit for each room is built in a factory, a floor material and a wall material are attached to the interior for interior decoration, and the completed unit completed in the factory is used as a trailer. The house is completed by stacking and transporting it to the construction site, lifting the unit with a crane, and assembling.

[0005]

As shown in FIG. 5, the interior wall material structure covers the entire surface of a plurality of unit inner walls a by covering a synthetic resin wallpaper b such as a general-purpose vinyl wallpaper with an adhesive c on the unit inner wall a. It is attached to the surface.

[0006]

[0004]

[0007]

However, various kinds of strain force are applied during loading, transportation, suspension work by a crane, etc. of the unit having the wall material structure with the interior, and this strain force is the weakest in the unit. As a result of concentrating in the vicinity of the joint d of the unit inner wall a, which is a part, the synthetic resin wallpaper b attached to the surface of the unit inner wall a is likely to tear and crack near the joint d. For this reason, there has been a problem that it takes time and labor to repair the wallpaper such as replacing the wallpaper after assembling the unit house.

[0008]

The present invention solves the above-mentioned problems of the conventional wall material structure for a unit house, does not crack the wallpaper, and therefore does not require repair such as replacement of the wallpaper after the unit house is assembled. It is intended to provide a wall material structure for use and a construction method thereof, and a wall material used for the wall material structure.

[0009]

[0006]

[0010]

A wall material structure for a unit house of the present invention which achieves the above object is formed by sequentially laminating an adhesive and a release paper on the surface of the inner wall of each unit and on the lower surface of one end. Synthetic resin wallpaper, than the end of the inner wall of the unit so that the end on the side where the adhesive and release paper are laminated overlaps the end of the synthetic resin wallpaper that is adhered to the adjacent inner wall of the unit. It is characterized in that it is extended and the other end is attached so as to terminate in the vicinity of the joint of the inner wall of the unit.

[0011]

In the above wall material structure for a unit house,
As shown in Fig. 1, the side of the synthetic resin wallpaper pasted on the inner wall of the unit, where the adhesive and the release paper are not laminated, has enough space to hit nails when the inner wall of the unit is attached. It should be terminated.

[0012]

With such a structure, the work of removing the unnecessary end portion after the synthetic resin wallpaper is cut while the end portions of the synthetic resin wallpaper are joined together becomes easy.

[0013]

Similarly, also on the side where the adhesive and the release paper are laminated, as shown in FIG. 1, when attaching the inner wall of the unit, leaving an unadhered portion having a width sufficient to hit a nail or the like. It is desirable to attach synthetic resin wallpaper to the inner wall of the unit. Also, if the adhesive and release paper are laminated in such a position that the vicinity of the seam of each unit inner wall is in a non-adhered state, a step due to an error in the thickness of the unit inner wall itself or a unit inner wall may be attached. Unevenness due to nails or the like can be prevented from appearing on the surface of the synthetic resin wallpaper, which is preferable.

[0014]

In one aspect of the invention, the synthetic resin wallpaper is lined with peel-up backing paper.

[0015]

Further, in another aspect of the present invention, the synthetic resin wallpaper stuck to the inner wall of the one unit has a gradient so that it becomes thinner toward the end on the side where the adhesive and the release paper are laminated. It is attached.

[0016]

Further, the method for constructing a wall material for a unit house according to the present invention is such that the end portions of the synthetic resin wallpaper in the wall material structure for a unit house are overlapped with each other, and the overlapped end portions are connected with each other by the seam. Cut along a cutting line almost parallel to
After removing the unnecessary edges cut off at each end and the release paper laminated on one end, joining the end faces of each end and adhering the one end to the surface of the inner wall of the unit. It is characterized by.

[0017]

Further, the wall material of the present invention comprises a synthetic resin wallpaper in which a patch and a release paper are sequentially laminated on the lower surface of one end on the surface of a plate-shaped substrate, and the adhesive and the release paper are laminated. The end of the plate-shaped substrate is extended from the end of the plate-shaped substrate, and the other end is attached in a state of terminating near the end of the plate-shaped substrate. It is a thing. The material of the plate-shaped substrate is not particularly limited, and any material commonly used for wall materials can be used. Specific examples include gypsum board, plywood, and perlite board.

[0018]

It goes without saying that the wall material can be used not only for a unit house but also as a normal wall material.

[0019]

[0015]

[0020]

In the wall material structure of the present invention, the adhesive of the synthetic resin wallpaper and the release paper are laminated until the work of loading the unit, carrying it, suspending it with a crane, etc. is finished until the unit is strained. The end on the opposite side is supported unattached on the end of the other wallpaper. Next, each end is overlapped and cut along a cutting line that is substantially parallel to the seam, and after removing the unnecessary edge edges that have been cut off and the release paper at one end, the end faces are joined together. At the same time, the one end is attached to the surface of the inner wall of the unit to complete the interior of the wall material structure.

[0021]

Therefore, if the ends of the adhesive and the release paper of the synthetic resin wallpaper, which are adhered to the surface of the inner wall of each unit, on the non-laminated side are terminated before the joint of the inner wall of the unit, Since the synthetic resin wallpaper is not attached to the seam of the unit inner wall, cracks do not occur in the synthetic resin wallpaper even if strain is applied to the vicinity of the seam of the unit inner wall. In addition, the adhesive of the synthetic resin wallpaper and the end of the release paper on the side where the release paper is not laminated are pasted onto the seam of the unit inner wall, and a strain force is applied near the seam of the unit inner wall to the synthetic resin wallpaper. Even if cracks occur, make sure that the end on the side where the adhesive and release paper are laminated overlaps the end of the synthetic resin wallpaper stuck to the adjacent unit inner wall, Is also extended to cover the seam of the inner wall of the unit, while the cracks are torn off when the interior of the wall material structure is completed, so no separate repairs such as replacing synthetic resin wallpaper are required. ..

[0022]

In one aspect of the present invention, since the synthetic resin wallpaper is lined with peel-up backing paper, unnecessary edges of the synthetic resin wallpaper attached to the surface of the inner wall of the unit are peeled off. By simply leaving a thin backing paper layer on the surface of the inner wall of the unit, the unnecessary edges can be peeled off cleanly, and a smooth adhesive surface can be provided to one of the edges to be attached thereafter.

[0023]

Further, according to one aspect of the present invention, a synthetic resin wallpaper stuck to the inner wall of the unit is coated with an adhesive layer such as a double-sided adhesive tape laminated on the end of the wallpaper and a peel-up backing paper. A step is formed on the joint surface by making a gradient so that it becomes thinner toward the end on the side where the adhesive and the release paper are laminated to the extent that the increase in the thickness at the joint end of the wallpaper due to the residual layer is compensated. It is prevented from occurring.

[0024]

Further, it goes without saying that the wall material of the present invention has the above-mentioned effects when it is used for a unit house, and even if it is used as a wall material for an ordinary house or the like, the wall material is attached. After that, after overlapping each end of the synthetic resin wallpaper and cutting along the cutting lines that are almost parallel to the seam, after removing the unnecessary edge cut off at each end and the release paper at one end Since the interior is completed only by the simple work of joining the end faces and adhering the one end to the surface of the inner wall of the unit, even an unskilled worker can easily perform the construction in a short time.

[0025]

[0020]

[0026]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 3 show an embodiment of the wall material structure for a unit house according to the present invention, and are enlarged cross-sectional views of the unit house wall material structure in the vicinity of the joint of the unit inner wall.

[0027]

In FIG. 1, synthetic resin wallpaper 3, 3'is provided on the surface of each unit inner wall 1, 1'with an adhesive 10, 10 '.
Thus, each unit is attached with an unattached portion of about 5 to 10 mm from the end of the inner wall of the unit so that the inner wall of the unit is sufficiently attached with a nail. Each wallpaper 3, 3 '
Is a publicly known one in which synthetic resin layers 5, 5'of vinyl chloride resin, acrylic resin or the like are laminated on a peel-up backing paper 4 produced by a two-layer papermaking method or the like. The synthetic resin layers 5 and 5 ′ may be transferred onto a backing paper by calendering and foamed and embossed, or may be laminated by a coating method using a doctor knife or a roll as a paste composition or a rotary screen method. It may also be coated as an emulsion. The synthetic resin layers 5 and 5'may be foam layers or non-foam layers. In the case of foaming, the foaming method may be either chemical foaming, mechanical foaming, or foaming with an expanding agent such as microcapsules.

[0028]

The surface may or may not be embossed. The end 3a of the synthetic resin wallpaper 3 attached to one unit inner wall 1 of the adjacent unit inner walls overlaps the end 3'a of the synthetic resin wallpaper 3'attached to the other unit inner wall 1 '. It is provided by extending to the position,
The double-sided adhesive tape 6 and the release paper 7 are sequentially laminated on the lower surface of the end portion 3a. Therefore, one end 3 of the wallpaper 3
The a is supported in an unattached state on the end 3'a of the other wallpaper 3 '.

[0029]

The wall material for the unit house having the above structure is manufactured in the factory, and the assembly of the unit is completed, that is, the work of applying the strain to the unit, such as loading the unit, carrying it, and suspending it with a crane, is completed. Hold the state. After these operations are completed, as shown in FIG. 2, the end portions 3a and 3'a are overlapped with each other, and the end portions 3a and 3'are cut by a cutter 9 along a cutting line 8 substantially parallel to the seam 2.
Cut a. Next, the unnecessary edges, that is, the end portions 3a, the double-sided adhesive tape 6, and the release paper 7 cut to the right of the cutting line 8 in FIG. 2 and the cutting line in FIG. Remove the part to the left of 8. In this case, peeling off the unwanted edge of the end 3'a leaves a thin layer of peel-up backing paper 4'a (FIG. 3) on the adhesive layer 10 ', and at the end 3a to be subsequently joined. It provides a smooth adhesive surface. After removing the unnecessary edge portions in this way, the release paper 7 laminated on the lower surface of the end portion 3a is removed, and as shown in FIG. Part 3a
The lower surface of the sheet is attached to the remaining backing layer 4'a on the inner wall 1'of the unit via a double-sided adhesive tape. In this way, the interior of the wall material structure for the unit house is completed.

[0030]

In this embodiment, since the synthetic resin wallpaper is not attached in the vicinity of the seam 2, an error in the thickness of the inner wall of the unit itself and unevenness caused by nails or the like appear on the surface of the synthetic resin wallpaper. Never.

[0031]

FIG. 4 shows another embodiment of the wall material structure for a unit house according to the present invention, and is a sectional view similar to FIGS.

[0032]

In the embodiment shown in FIGS. 1 to 3, the wallpaper structure after the interior is completed has a thickness of these layers due to the presence of the residual backing layer 4'a and the double-sided adhesive tape 7, as can be seen from FIG. The end portion 3a rises by the total amount, and a slight step is formed on the joint surface between the end portion 3a and the end portion 3'a.
This step is not conspicuous when the wallpaper surface has unevenness due to embossing and does not cause any particular problem, but when embossing is not applied and the surface of the wallpaper is smooth, such a step is generated. It may noticeably deteriorate the appearance.

[0033]

Therefore, in the embodiment shown in FIG. 4, the synthetic resin wallpaper 3 attached to the inner wall 1 of the unit is inclined so as to become gradually thinner toward the end 3a. This compensates for the increase in the thickness of the joining end portion due to the residual layer 4'a of the peel-up backing paper and the double-sided adhesive tape 7, and prevents a step from being formed on the joining surface. Such a gradient of the wallpaper 3 can be easily realized by, for example, inclining the doctor knife when the synthetic resin is coated on the backing paper with the doctor knife. Further, when the backing paper is coated with the synthetic resin by the rotary screen, it can be easily realized by adjusting the size of the mesh of the rotary screen.

[0034]

As in each of the above embodiments, if a peel-up backing paper is used as the backing paper for the wallpaper, there is an effect that a smooth adhesive surface can be provided after the unnecessary edges are peeled off. The present invention is not limited to this, and can also be applied to the case of using a wallpaper that uses a backing paper other than the peel-up backing paper or a wallpaper that does not use a backing paper as the backing paper.

[0035]

[0029]

[0036]

As described above, according to the present invention, the end portion of the synthetic resin wallpaper stuck to the surface of the inner wall of each unit on the side where the adhesive and the release paper are not laminated is the unit. If it ends before the seam of the inner wall, the synthetic resin wallpaper is not attached to the seam of the inner wall of the unit.
Even if strain is applied near the seam of the unit inner wall, the synthetic resin wallpaper will not crack. In addition, the adhesive of the synthetic resin wallpaper and the end of the release paper on the side where the release paper is not laminated are pasted onto the seam of the unit inner wall, and a strain force is applied near the seam of the unit inner wall to the synthetic resin wallpaper. Even if cracks occur, make sure that the end on the side where the adhesive and release paper are laminated overlaps the end of the synthetic resin wallpaper stuck to the adjacent unit inner wall, Is also extended to cover the seam of the inner wall of the unit, while the cracks are torn off when the interior of the wall material structure is completed, so no separate repairs such as replacing synthetic resin wallpaper are required. ..

[0037]

Further, after the unit is assembled, the respective end portions are overlapped with each other and cut along the cutting lines which are substantially parallel to each other at the seam, and the unnecessary end edge portion cut off at each end portion and the release paper at one end portion are removed. After that, it is a simple work of joining the end faces of each end and adhering the one end to the surface of the inner wall of the unit, and even an unskilled worker can easily and quickly install the interior of the wall material structure. Can be completed.

[0038]

Further, in one aspect of the present invention, since the synthetic resin wallpaper is lined with peel-up backing paper, unnecessary edges of the synthetic resin wallpaper attached to the surface of the inner wall of the unit are peeled off. Occasionally, a thin backing paper layer is left on the surface of the inner wall of the unit to cleanly remove the unnecessary edge portion, and it is possible to provide a smooth adhesive surface to one end portion to be subsequently attached.

[0039]

Further, according to one aspect of the present invention, the synthetic resin wallpaper stuck to the inner wall of the unit is composed of a sticking agent layer such as a double-sided adhesive tape laminated at the end and a residual layer of peel-up backing paper. There is a gap in the joint surface by grading so that it becomes thinner toward the end where the adhesive and release paper are laminated to the extent that the increase in thickness at the joint end of the wallpaper is compensated. Is prevented.

[0040]

Further, it goes without saying that the wall material of the present invention exhibits the above effects by being used for a unit house, and even if it is used as a wall material for a normal house, the wall material is attached. After that, after overlapping each end of the synthetic resin wallpaper and cutting along the cutting lines that are almost parallel to the seam, after removing the unnecessary edge cut off at each end and the release paper at one end Since the interior is completed only by the simple work of joining the end faces together and adhering the one end to the surface of the inner wall of the unit, in the present day when skilled workers are insufficient, the work period can be shortened and simplified. It has an excellent effect.
