[First Embodiment]
In FIG. 1 thru | or FIG. 3, the joint material 1 for wallpaper of this invention has the standing part 2 and the sticking part 3 extended from the one side of the standing part 2. As shown in FIG. The wallpaper joint member 1 of the present invention does not have the sticking part 3 as described above on the other side of the standing part 2.
The wallpaper joint member 1 is provided between the side edges of two adjacent wallpaper (first wallpaper and second wallpaper) at the time of construction.
The wallpaper joint member 1 is a long member extending linearly as a whole. Therefore, the standing part 2 and the sticking part 3 are also long. Although the length of the longitudinal direction of the wallpaper joint member 1 is not specifically limited, For example, it is 50 cm-300 cm.

  The elongate standing portion 2 includes a first side surface portion 21 that can abut one side edge of the first wallpaper, and a second side surface portion 22 that can abut one side edge of the second wallpaper. A front surface portion 23 provided across the front of the first side surface portion 21 and the front surface of the second side surface portion 22, a back surface portion 24 located on the opposite side of the front surface portion 23 and in contact with the wall surface during construction, Have A slit 4 extending in the longitudinal direction is formed in the back surface portion 24. The slit 4 communicates with the hollow portion 5 in the standing portion 2.

The affixing portion 3 extends outward from the rear of the first side surface portion 21. The pasting portion 3 is a portion interposed between the wall surface and the first wallpaper when the wallpaper joint member 1 is constructed.
The standing portion 2 and the pasting portion 3 are integrally formed. However, the wallpaper joint member 1 may be configured by forming the standing part 2 and the sticking part 3 separately and fixing the sticking part 3 to the standing part 2 using an adhesive.

Specifically, the standing portion 2 includes a first side wall 211 including the first side surface portion 21, a surface wall 231 including the surface portion 23, a second side wall 221 including the second side surface portion 22, The first back wall 241 including the back surface part 24 and the second back wall 242 are included. Each of these walls 211, 221, 231, 241, 242 has an elongated plate shape extending in the longitudinal direction. The standing portion 2 is configured by connecting adjacent walls except for the space between the first back wall 241 and the second back wall 242.
Specifically, the left end of the first back wall 241 and the rear end of the first side wall 211 are connected, the front end of the first side wall 211 and the left end of the surface wall 231 are connected, and the right end of the surface wall 231 is connected. And the front end of the second side wall 221 is continuously provided, and the rear end of the second side wall 221 and the right end of the second back wall 242 are continuously provided. The hollow part 5 has arisen in the range enclosed by each of these walls. That is, the hollow portion 5 is a space defined by the inner surfaces of the first side wall 211, the surface wall 231, the second side wall 221, the first back wall 241, and the second back wall 242.
The right end of the first back wall 241 and the left end of the second back wall 242 are spaced apart from each other at a required interval, and the slit 4 is formed between them. The slit 4 communicates with the hollow portion 5. The slit 4 is formed in the middle of the back surface portion 24 in the width direction. In the present embodiment, the slit 4 is formed at the center in the width direction of the standing portion 2, and the width of the first back wall 241 and the width of the second back wall 242 are substantially the same. In this specification, the width is the length in the width direction, and the width direction is a direction (short direction) orthogonal to the longitudinal direction.

In the standing portion 2, the first side surface portion 21 is configured from the outer surface of the first side surface wall 211, the surface portion 23 is configured from the outer surface of the surface wall 231, and the second side surface portion 22 is configured from the second side surface wall. The rear surface portion 24 is composed of the outer surface of the second rear surface wall 242 and the outer surface of the first rear surface wall 241. The outer surface of the second back wall 242 and the outer surface of the first back wall 241 are both flat and on the same plane. Accordingly, the back surface portion 24 is flat and can be along the wall surface.
The front surface portion 23 is formed in a flat shape substantially parallel to the back surface portion 24. But the surface part 23 is not restricted to a flat surface, For example, you may form in the arc-shaped surface which swells ahead.
The 1st side surface part 21 and the 2nd side surface part 22 are made into the inclined surface which inclined inward as it went back from the front. Each inclination angle is an acute angle, preferably 45 degrees to 85 degrees, and more preferably 50 degrees to 80 degrees. The tilt angle refers to the smaller angle of the two angles formed by the first side surface portion 21 and the second side surface portion 22 with respect to the plane including the back surface portion 24.
Preferably, the first side surface portion 21 and the second side surface portion 22 are substantially line symmetrical with respect to an imaginary line that passes through the center of the front surface portion 23 in the width direction and is perpendicular to the back surface portion 24. . The substantially line-symmetrical shape means a line-symmetrical shape except that the pasting portion 3 is extended from the first side surface portion 21. That is, when the wallpaper joint member 1 is viewed from the longitudinal direction, the shape of the first side surface portion 21 excluding the pasting portion 3 and the shape of the second side surface portion 22 are axisymmetric shapes. But the said 1st side surface part 21 and the 2nd side surface part 22 are not necessarily limited to when formed in the line symmetrical shape.

The sticking part 3 is formed in a thin plate shape as a whole, the base end thereof is connected to the first side face part 21 and the tip thereof is a free end. The length of the sticking part 3 in the longitudinal direction is the same as that of the standing part 2, and the back surface of the sticking part 3 is a flat surface continuous to the back face part 24 of the standing part 2.
The thickness of the sticking part 3 may be uniform from the base end to the tip, but when the wallpaper is pasted on the surface of the sticking part 3, a step corresponding to the thickness of the tip of the sticking part 3 In order not to appear on the surface, it is preferable that the thickness of the sticking portion 3 is the thickest at the proximal end and gradually decreases toward the distal end. In particular, it is more preferable that the tip of the sticking part 3 is formed in a pointed shape.
Therefore, the surface of the sticking part 3 is an inclined surface that is inclined backward as it goes from the base end to the tip of the sticking part 3. In addition, as shown in FIG. 3, the surface of the sticking part 3 is flat from the proximal end of the sticking part 3 to the middle part toward the tip, and an inclined surface that gradually slopes backward from the halfway part toward the tip. May be.

The thickness at the base end of the sticking part 3 is, for example, 0.2 mm to 2.0 mm, preferably 0.3 mm to 1.5 mm, and more preferably 0.4 mm to 1.0 mm. If the thickness at the proximal end of the affixing part 3 is too thin, the connection strength of the affixing part 3 to the standing part 2 may be insufficient, while if the thickness at the proximal end of the affixing part 3 is too thick, the affixing part The wallpaper affixed to the surface of 3 may appear to swell and the appearance of the wallpaper structure may deteriorate.
The thickness at the tip of the sticking part 3 is, for example, more than 0 and 0.8 mm or less, and preferably 0.1 mm to 0.6 mm.

Although the width | variety of the sticking part 3 is not specifically limited, For example, they are 5 mm-30 mm, Preferably they are 5 mm-25 mm, More preferably, they are 5 mm-20 mm. If the width of the affixing part 3 is too small, the mounting stability of the wallpaper joint member 1 to the wall surface is deteriorated. If the width of the affixing part 3 is too large, the material for forming the affixing part 3 is increased. There is a possibility that the affixing part 3 may be deformed or missing at the time of construction, resulting in poor handling.
The width of the surface portion 23 (corresponding to the width of the standing portion 2) is 1 mm to 20 mm, preferably 2 mm to 15 mm, and more preferably 3 mm to 10 mm. If the width of the erected portion 2 is too small, the erected portion 2 may be lost during construction, resulting in poor handling. Further, if the width of the standing portion 2 is too large, the wallpaper joint member 1 becomes too conspicuous and the appearance of the wallpaper structure is deteriorated, and the wallpaper joint member 1 is cut using scissors, a cutter or the like. Can be difficult.
In the present embodiment in which the first side surface portion 21 and the second side surface portion 22 are inclined inwardly toward the rear, the width of the back surface portion 24 is slightly smaller than the width of the front surface portion 23.

If necessary, a decorative layer (not shown) may be provided on the outer surface of the standing portion 2. For example, a decorative sheet is attached to the first side surface portion 21, the surface portion 23, and the second side surface portion 22. By providing the decorative layer, the standing portion 2 exposed between the wallpaper at the time of construction can be clearly displayed.
As the decorative layer, a thin sheet on which a desired pattern is printed can be used. The thickness of the sheet is not particularly limited, but is, for example, 20 μm to 200 μm. The decorative sheet is fixed to the outer surface of the standing portion 2 using an adhesive or an adhesive. Moreover, you may provide a decorative layer by printing a desired pattern or a color directly on the outer surface of the standing part 2, without using a decorative sheet.

The projecting height of the standing portion 2 is not particularly limited, but the side edge of the first wallpaper exceeds the front end of the first side surface portion 21 so as not to look out from the surface portion 23. Is preferably large. Specifically, the protruding height of the standing portion 2 is 1 mm to 10 mm, preferably 2 mm to 5 mm, although it depends on the thickness of the wallpaper.
In addition, the protrusion height of the said standing part 2 is the length from the front end of the 1st side part 21 to a back end (sticking part 3). Since the height of the 2nd side part 22 in which the sticking part 3 is not provided is longer than the height of the 1st side part 21, if the protrusion height of the 1st side part 21 is the said length, it will be 2nd wallpaper. The side edge of the second side portion 22 does not look out from the front end.

The thicknesses of the first side wall 211, the front wall 231, the second side wall 221, the first back wall 241 and the second back wall 242 constituting the standing portion 2 are, for example, 0. 5 mm to 1.5 mm, preferably 0.8 mm to 1.2 mm.
Further, the width of the slit 4 is not particularly limited. However, if the width is too large, the first back wall 241 and the second back wall 242 substantially do not exist. If the width is too small, it is not meaningful to provide the slit 4. 0.2 mm to 2 mm, preferably 0.7 mm to 1.2 mm.

The material for forming the wallpaper joint member 1 is not particularly limited, and examples thereof include synthetic resins and metals such as aluminum. The wallpaper joint member 1 is preferably formed of a synthetic resin because it can be formed inexpensively and is easily cut.
As the synthetic resin, for example, thermoplastic resins such as vinyl chloride, polyethylene, polypropylene, polyethylene terephthalate, polymethyl methacrylate, polycarbonate, and ABS resin can be used.
Since the slit 4 is formed in the standing part 2, the wallpaper joint member 1 of the present invention is less likely to warp even if it is manufactured from a synthetic resin.
Specifically, the molten thermoplastic resin is extruded from a pressure-resistant mold having a gap having a shape as shown in FIG. 3, and the molded product is rapidly cooled with water, thereby being shown in FIGS. Such a wallpaper joint member 1 can be manufactured. During this water cooling, water enters the hollow portion 5 from the slit 4, so that the entire standing portion is rapidly cooled, and deformation and warpage are unlikely to occur. Thus, the wallpaper joint member 1 having high straightness is obtained. Can do. The cooled water flows out and evaporates from the hollow portion 5 to the outside through the slit 4. In addition, when this slit 4 is not formed, since water hardly enters the hollow part 5 and water contacts only the outer surface of the upright part 2, heat remains in the upright part 2, and water cooling Later, as a result of gradually radiating heat and causing a difference in shrinkage, warping may occur.

  The wallpaper joint member 1 of the present invention is cut into an appropriate length as needed and attached to a wall surface. Since the standing part 2 is hollow, the wallpaper joint member 1 can be cut well using a cutting tool such as scissors or a cutter. In particular, since the slit 4 is formed in the back surface portion 24, it is possible to prevent the standing portion 2 from being deformed when the pressure by the cutting tool is applied and the stress from being concentrated. For this reason, the joint member 1 for wallpaper becomes difficult to be damaged or deform | transformed at the time of a cutting | disconnection.

  The construction method of the wallpaper structure using the wallpaper joint member 1 includes the step of pasting one wallpaper on the wall surface, and the second side surface portion 22 of the wallpaper joint member 1 on the side edge of the wallpaper. The step of attaching the joint material 1 for wallpaper to the wall surface while being abutted, the first side surface portion 21 of the joint member 1 for wallpaper being applied, and the surface of the pasting portion 3 while the side edge of another wallpaper is being abutted Attaching to the wall surface.

Specifically, as shown in FIGS. 4 and 5, one wallpaper 92 (second wallpaper) with the wallpaper adhesive 82 applied to the back surface is affixed to the wall surface 10. The adhesive 83 for members is apply | coated to the back surface part 24 of the joint material member 1 for wallpaper, and the back surface of the sticking part 3, and the 2nd side surface of the joint material member 1 for wallpaper is applied to one side edge of the said 2nd wallpaper 92 completed. The parts 22 are brought into contact with each other and attached while pressing the back surface part 24 of the wallpaper joint member 1 and the back surface of the pasting part 3 against the wall surface 10. Since the pasting part 3 is not extended from the 2nd side surface part 22 which is the other side of the standing part 2, the joint material member 1 for wallpaper of this invention is 2nd in the side edge of the completed 2nd wallpaper 92. By applying the side surface portion 22, the wallpaper joint member 1 can be positioned and attached to the wall surface 10.
In addition, in the front-end | tip of the sticking part 3 of the wallpaper joint member 1, when the comparatively big level | step difference has arisen between the front-end | tip and the wall surface 10, the putty agent 6 etc. are apply | coated and the said level | step difference is filled and leveled. Is preferable. In addition, instead of or in combination with the application of the putty agent 6, it is preferable to scrape the tip of the affixing portion 3 of the wallpaper joint member 1 to eliminate the step.

In the wallpaper joint member 1 of the present invention, the slit 4 is formed in the back surface portion 24, and therefore, when the wallpaper joint member 1 is pressed against the wall surface 10, the excess member adhesive 83 passes through the slit 4 to form a hollow portion. Go into 5. For this reason, it can suppress that the adhesive agent 83 for excess members protrudes from the edge of the joint material member 1 for wallpaper. Further, when the member adhesive 83 that has entered the hollow portion 5 is cured, the cured adhesive 83 reinforces the standing portion 2, so that the standing portion 2 is not affected even if a foreign object hits the hollow standing portion 2. It becomes difficult to be crushed.
Furthermore, the wallpaper joint member 1 can be firmly fixed to the wall surface 10 by the anchor effect of the member adhesive 83 after entering and curing the hollow portion 5. In particular, since the width of the slit 4 is smaller than the width of the hollow portion 5, the anchor effect of the member adhesive 83 that has entered the hollow portion 5 becomes higher.
Moreover, since the slit 4 is formed in the back surface portion 24 (that is, the back surface portion 24 is composed of the first back surface wall 241 and the second back surface wall 242), the standing portion 2 is easily curved in the width direction. The wallpaper joint member 1 can be brought into close contact with the wall surface 10 along the unevenness of the wall surface 10.

After attaching the joint material 1 for wallpaper to the wall surface 10 as described above, one side edge of another wallpaper 91 (first wallpaper) having the back surface coated with the wallpaper adhesive 81 is attached to the wall having been installed. The first wallpaper 91 is affixed to the surface and the wall surface 10 of the affixing portion 3 of the wallpaper joint member 1 while abutting against the first side surface portion 21 of the wallpaper joint member 1. When the first wallpaper 91 is pasted, the pasting portion 3 of the wallpaper joint member 1 is interposed between the first wallpaper 91 and the wall surface 10.
After that, the wallpaper joint member 1 is arranged at the boundary portion of the adjacent wallpaper by attaching the next wallpaper joint member 1 in the same manner to the other side edge of the first wallpaper 91 that has been constructed. Wallpaper structure 11 can be obtained.

In this way, when the wallpaper joint member 1 of the present invention is used, the wallpaper joint member 1 can be attached and the wallpapers 91 and 92 can be attached in sequence without the wall surface 10 being assigned in advance.
In addition, since the first side surface portion 21 and the second side surface portion 22 of the standing portion 2 are substantially line symmetrical, the boundary between the adjacent two wallpaper 91 and 92 is not noticeable, and the wallpaper is beautiful in appearance. The structure 11 can be obtained.
Then, after the construction, there is a case where it is desired to replace one wallpaper joint member 1 or one wallpaper 91 due to damage to the wallpaper joint member 1 or partial contamination of the wallpaper. When replacing the conventional cloth joint member 1, it is necessary to peel off at least the two wallpaper abutted against the cloth joint member 1, but according to the wallpaper joint member 1 of the present invention, it is stuck on the surface of the sticking part 3. The wallpaper joint member 1 can be removed simply by peeling off the first wallpaper 91.

In some cases, it is desired to replace some of the wallpaper while leaving the wallpaper of the existing wallpaper structure in which the wallpaper joint member 1 is not used. In this regard, if the wallpaper joint member 1 of the present invention is used, the second side face 22 is abutted against the side edge of the remaining wallpaper, a new wallpaper is pasted, and the side edge of the new wallpaper is the first side face. By matching with 21, a wallpaper structure that has been partially replaced can be constructed. By attaching the joint material 1 for wallpaper as described above, the boundary between the new wallpaper and the existing wallpaper can be finished beautifully.
In addition, since the 1st and 2nd side surface parts 21 and 22 are symmetrical, the joint material member 1 for wallpaper of this invention can also be reversed and used. That is, the existing wallpaper may remain on both sides of the new wallpaper, but if the wallpaper joint member 1 is inverted, the second side surface 22 is provided on any of the existing wallpaper. Can be matched. The wallpaper joint member 1 of the present invention having high straightness also has high straightness of the side surface portion thereof, and therefore, when the first and second side surface portions 21 and 22 are brought into contact with the wallpaper, the gap between the side surface portion and the wallpaper. Is less likely to occur, making it possible to achieve a more beautiful finish.

  The joint material for wallpaper of the present invention is not limited to the first embodiment, and can be variously changed within the range intended by the present invention. Hereinafter, although other embodiment of this invention is described, description is abbreviate | omitted about the structure, effect, and usage method similar to the said 1st Embodiment, and a term and a code | symbol are used as it is.

[Second Embodiment]
In the said 1st Embodiment, although the slit 4 formed in the back surface part 24 is arrange | positioned in the center part of the width direction of the standing part 2, it is not limited to this, For example, it shows to Fig.6 (a) As described above, the slit 4 may be formed closer to the first side surface portion 21 with reference to the central portion in the width direction of the standing portion 2, or, as shown in FIG. 2 may be formed closer to the second side surface portion 22 with respect to the center portion in the width direction. As described above, the slit 4 may be formed in the middle portion in the width direction of the standing portion 2, but among them, the slit 4 is disposed near the center portion in the width direction of the standing portion 2 or the first side surface portion 21. It is preferable. Since the slit 4 is formed closer to the first side surface portion 21, the second back surface wall 242 becomes relatively larger, so that the wall surface 10 of the back surface portion 24 (second back surface wall 242) corresponding to the second side surface portion 22. Therefore, the wallpaper joint member 1 can be stably attached to the wall surface 10.

[Third Embodiment]
Moreover, in the said 1st Embodiment, although the 1st side surface part 21 and the 2nd side surface part 22 are made into the inclined surface inclined inward as it goes back from the front, it is not limited to this, For example, FIG. As shown in FIG. 7, the first side surface portion 21 and the second side surface portion 22 may be flat surfaces that are substantially orthogonal to the back surface portion 24. Contrary to the form, the first side surface portion 21 and the second side surface portion 22 may be inclined surfaces that are inclined outwardly from the front toward the rear. Moreover, the 1st side part 21 and the 2nd side part 22 are not restricted to a substantially line symmetrical form, Asymmetrical form may be sufficient. Examples of the asymmetric shape include a case where the first side surface portion 21 is an inclined surface and the second side surface portion 22 is a flat surface substantially orthogonal to the back surface portion 24.
The wallpaper joint member 1 of the third embodiment is also highly straight, and even when such a wallpaper joint member 1 is used, the gap between the side surface portion and the wallpaper is less likely to occur as in the first embodiment. It becomes possible to finish more beautifully.

[Fourth Embodiment]
In the first embodiment, the surface portion 23 of the standing portion 2 is formed in a flat shape (since the surface portion 23 is flat, the outer shape of the standing portion 2 is formed in a substantially rectangular shape. For example, as shown in FIG. 8A, the surface portion 23 may be formed in an arcuate surface that swells outward.
Moreover, in the said 1st Embodiment, although the cross-sectional shape of the hollow part 5 is formed in the substantially rectangular shape, it is not limited to this, For example, as shown to the same figure (b), it forms in a substantially elliptical shape etc. May be.
Since the joint material for wallpaper of the present invention is less likely to be deformed or warped during production, the surface portion 23 of the standing portion 2 and the inner surface of the hollow portion 5 can be stably formed in a curved surface shape.

[Fifth Embodiment]
Moreover, in the said 1st Embodiment, although the 1st side part 21 and the 2nd side part 22 consist of a flat surface, as shown in FIG. 9, for example, a part of 1st side part 21 and the 2nd side part 22 Moreover, the recessed part 6 dented inward may be formed.
For example, in the example shown in FIG. 9A, the first side surface portion 21 and the second side surface portion 22 are flat surfaces that are substantially orthogonal to the back surface portion 24 in the middle from the front, and from the middle to the rear. The inclined surface is inclined inward. The inwardly inclined portion is a recessed portion 6 that is recessed inward. In the illustrated example, a part of the first side part 21 (rear part) and a part of the second side part 22 (rear part) are respectively provided. A recess 6 is provided.
In the example shown in FIG. 2B, the first side surface portion 21 and the second side surface portion 22 are flat surfaces that are substantially orthogonal to the back surface portion 24 in the middle from the front, and from the middle to the rear. It is assumed to be a stepped surface that is recessed in an approximately U shape inward. The indented portion is a recessed portion 6 that is recessed inward. In the illustrated example, a part of the first side part 21 (rear part) and a part of the second side part 22 (rear part) A recess 6 is provided.
