A cross joint member is disclosed.
The construction of the cross joint member is to attach the base plate to the wall surface, attach the wallpaper to the surface of the pair of sticking parts while applying the edge of the wallpaper to the standing part, and then attach the stopper to the groove part of the standing part. Is done by.

However, when the conventional cross joint member is used, the wall surface is assigned in advance (the position where the wallpaper is applied to the wall surface is determined in advance), and a plurality of base plates are attached at predetermined intervals according to the assignment. After that, the wallpaper must be attached in sequence. In addition, after attaching the wallpaper, you must also install the fasteners.
Further, after the cross joint member and wallpaper are applied, for example, when one cross joint member is damaged and replaced, there is also a problem that the left and right wallpaper must be peeled off.
In addition, about the existing wallpaper structure constructed without using the cross joint member, when a part of the wallpaper is replaced, there is a step at the boundary between the new wallpaper and the existing wallpaper. The appearance of the structure is impaired.

Further, Patent Document 2 includes a rising piece, a decorative cover piece having a surface layer made of a soft thermoplastic resin, and an insertion recess provided between these pieces. The lower part of the decorative cover piece is an elastic body made of a soft thermoplastic resin continuous from the surface layer so that the upper end of the flooring inserted into the insertion recess can be sandwiched between A parting material having a hook shape in a sectional view in which the tip of an elastic body is tapered is disclosed. In this parting material, a gap is formed between the tip of the decorative cover piece (elastic body) and the upright piece, and the upper end portion of the flooring is inserted into the insertion recess from this gap and used.
However, in such a parting material, since the tip of the decorative cover piece is separated from the rising piece, when the decorative cover piece is pressed from above, the decorative cover piece swings, and the connecting portion of the decorative cover piece and the rising piece Stress concentrates on the side opposite to the gap. Therefore, when a cutter or the like is pressed from above the decorative cover piece to cut this parting material, the connecting portion between the decorative cover piece and the rising piece is cracked, or the insertion recess (curved decorative cover piece) is crushed. There is a fear.
In addition, Patent Document 2 discloses a parting material attached to the upper end of a flooring or the like, but does not disclose any joint material for wallpaper provided at the boundary between adjacent wallpaper.

[First Embodiment]
1 and 2, the joint material 1 for wallpaper of the present invention has a standing portion 2 and a sticking portion 3 extending from one side of the standing portion 2. The wallpaper joint member 1 of the present invention does not have the above-mentioned pasting portion on the other side of the standing portion 2.
The wallpaper joint member 1 is provided between the side edges of two adjacent wallpaper during construction.
The wallpaper joint member 1 is an elongated member extending linearly as a whole. 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 standing portion 2 includes a first side surface portion 21 capable of abutting one side edge of the first wallpaper, a second side surface portion 22 capable of abutting one side edge of the second wallpaper, and a first side surface. The surface part 23 provided over the front of the part 21 and the front of the 2nd side part 22 and the back surface part 24 which is located in the opposite side to the surface part 23, and contact | connects a wall surface at the time of construction are included. Moreover, these 4 surface parts are connected in order of the 1st side surface part, the surface part, the 2nd side surface part, and the back surface part, and comprise the cross sectional view cyclic | annular form. Therefore, the outer peripheral shape of the standing portion 2 in a sectional view is annular. But since the sticking part 3 is extended from the 1st side part 21, the sticking part 3 shall be considered that it is connected continuously.

The affixing portion 3 extends outward from the rear of the first side surface portion 21. The affixing portion 3 is interposed between the wall surface and the first wallpaper during construction of the wallpaper joint member 1.
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 back surface portion 24 of the standing portion 2 is a flat surface so as to contact the wall surface. The surface portion 23 of the standing portion 2 is formed in a flat shape substantially parallel to the back surface portion 24 (wall surface). But the surface part 23 of the standing part 2 is not restricted to a flat surface, For example, you may be made into the arc-shaped surface which swells ahead.

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 in the width direction of the front surface portion 23 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.
The first side surface portion 21 and the second side surface portion 22 of the present embodiment are flat surfaces that are substantially orthogonal to the back surface portion 24, respectively. In other words, the first side surface portion 21 and the second side surface portion 22 are flat surfaces parallel to each other, and are formed so as to be substantially orthogonal to the wall surface at the time of construction.

The sticking part 3 is formed in a thin plate shape as a whole, its base end is connected to the first side face part 21 and its tip is a free end. The back surface 3 a of the sticking part 3 is a flat surface that is continuous with the back surface 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 stuck on the surface 3b of the sticking part 3, the step corresponding to the thickness of the tip of the sticking part 3 is the wallpaper. In order to prevent it from appearing 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 3b of the sticking part 3 is an inclined surface that gradually slopes backward as it goes from the base end to the tip of the sticking part 3. In addition, the surface 3b of the sticking part 3 may be a flat surface from the base end of the sticking part 3 to the middle part toward the tip, and may be an inclined surface that gradually slopes backward from the middle part toward the tip.

The thickness T3 at the proximal 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 T3 at the base end of the sticking part 3 is too thin, the connection strength of the sticking part 3 to the standing part 2 may be insufficient, while if the thickness T3 at the base end of the sticking part 3 is too thick, The wallpaper affixed to the surface 3b of the affixing part 3 appears to swell, and the appearance after construction may deteriorate.
The thickness at the tip of the sticking part 3 is, for example, more than 0 and 0.8 mm or less, preferably 0.1 mm to 0.5 mm.

Although the width W3 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 W3 of the affixing part 3 is too small, the mounting stability of the wallpaper joint member 1 to the wall surface is deteriorated, and if the width W3 of the affixing part 3 is too large, the material for forming the affixing part 3 increases. Therefore, the sticking part 3 may be deformed or missing at the time of construction, resulting in poor handling.
The width W2 of the standing portion 2 is 1 mm to 20 mm, preferably 1 mm to 15 mm, and more preferably 1 mm to 10 mm. If the width W2 of the erected part 2 is too small, the erected part 2 may be lost during construction, resulting in poor handling. If the width W2 of the standing portion 2 is too large, the wallpaper joint member 1 is too conspicuous and not only the appearance after construction is deteriorated, but also the wallpaper joint member 1 is cut using a scissors or a cutter. Can be difficult.
In the present embodiment in which the first side surface portion 21 and the second side surface portion 22 are flat surfaces substantially orthogonal to the back surface portion 24, the width W2 of the standing portion 2 is the same as that of the first side surface portion 21. It is equal to the distance from the second side surface portion 22.

  The total width of the wallpaper joint member 1 (total of the width W3 of the sticking portion 3 and the width W2 of the standing portion 2) is not particularly limited, but is, for example, 10 mm to 50 mm, preferably 10 mm to 40 mm, and more preferably. Is 10 mm to 20 mm. If the overall width of the wallpaper joint member 1 is too small, the mounting stability of the wallpaper joint member 1 on the wall surface is deteriorated. If the overall width of the wallpaper joint member 1 is too large, it takes time to cut the wallpaper joint member 1. Take it.

The height H2 of the first side surface portion 21 of the standing portion 2 is not particularly limited, but prevents the side edge of the first wallpaper from peeping out from the surface portion 23 beyond the front end of the first side surface portion 21. For this reason, the thickness is preferably equal to or greater than the thickness of the wallpaper. Specifically, the height H2 of the first side surface portion 21 of the standing portion 2 is 1 mm to 10 mm, preferably 1 mm to 5 mm, although it depends on the thickness of the wallpaper.
In addition, height H2 of the 1st side part 21 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 second side surface portion 22 where the affixing portion is not provided is longer than the height of the first side surface portion 21, if the height H2 of the first side surface portion 21 is the above length, The side end edge does not look out from the front end of the second side surface portion 22.

  In the wallpaper joint member 1 of the present invention, the four side surfaces of the first side surface portion 21, the second side surface portion 22, the front surface portion 23, and the back surface portion 24 continuously form an annular shape. Even when the standing portion 2 is pressed with scissors or a blade of a cutter, it is difficult to bend and stress is not easily concentrated on a part thereof. For this reason, the joint material 1 for wallpaper of this invention can be cut | disconnected favorably using scissors, a cutter, etc.

Moreover, in this embodiment, the joint material 1 for wallpaper which consists of the standing part 2 and the sticking part 3 is formed in the solid shape. The solid state means that there is no large cavity inside.
By making the standing part 2 and the sticking part 3 solid, the rigidity of the wallpaper joint member 1 can be increased, and when it is cut with scissors or a cutter, the standing part 2 and the sticking part 3 are It is hard to be crushed.

The material for forming the wallpaper joint member 1 is not particularly limited, and examples thereof include synthetic resin, metal, and wood. 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.
The wallpaper joint member 1 can be easily manufactured, for example, by extrusion molding of a synthetic resin.

  In addition, the adhesive may be apply | coated to the back surface part 24 of the joint material member 1 for wallpaper, and the back surface 3a of the sticking part 3. FIG. When an adhesive is applied, a release paper is temporarily attached to the adhesive layer (the adhesive layer and the release paper are not shown). An adhesive layer provided with such a release paper can be easily formed by using a known adhesive tape.

  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 process of attaching the joint material for wallpaper 1 to the wall surface while being abutted, the surface and the wall surface of the pasting portion of the other wallpaper while the side edge of the other wallpaper is abutted against the first side surface portion 21 of the joint material 1 for wallpaper A step of attaching to the substrate.

  Specifically, as shown in FIGS. 3 and 4, one wallpaper 92 is attached to the wall surface 10. Adhesive is applied to the back surface portion 24 of the wallpaper joint member 1 and the back surface 3a of the sticking portion 3 (adhesive is not shown), and one side edge 92a of the applied wallpaper 92 (second wallpaper 92). Next, the second side surface portion 22 of the wallpaper joint member 1 is abutted, and the back surface portion 24 of the wallpaper joint member 1 and the back surface 3a of the pasting portion 3 are attached to the wall surface 10. In addition, when the adhesive layer is provided in the wallpaper joint member 1, application | coating of the said adhesive agent is abbreviate | omitted.

Since the joint part 1 for wallpaper of this invention is not extending the sticking part 3 from the 2nd side part 22 which is the other side of the standing part 2, and the 2nd side part 22 is linear, construction The joint material 1 for wallpaper can be attached to the wall surface 10 by applying the second side surface portion 22 to the side edge 92 a of the already finished second wallpaper 92.
If a relatively large step is formed between the tip of the pasting portion 3 of the wallpaper joint member 1 and the wall surface 10, the step is eliminated by sanding the tip of the pasting portion 3. Alternatively, it is preferable to apply a putty agent or the like to fill the level difference and level.

The first wallpaper 91 is affixed to the surface 3 b and the wall surface 10 of the affixing portion 3 while abutting one side edge 91 a of the first wallpaper 91 on the first side surface portion 21 of the applied 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.
Since the first side surface portion 21 is a flat surface that is substantially orthogonal to the wall surface 10, the side edge 91 a of the first wallpaper 91 can be easily butted against the first side surface portion 21.

In addition, when the side edge 91a of the first wallpaper 91 is not linear, the first wallpaper 91 is temporarily pasted so that the side edge 91a overlaps the surface portion 23 of the standing portion 2, and a spatula or the like is used. Then, the side edge of the first wallpaper 91 is pushed into the corner where the first side surface 21 and the surface 3b of the pasting portion 3 intersect, and the side of the first wallpaper 91 along the first side surface 21 using a cutter. You may cut | disconnect an edge part in linear form, and you may face the 1st side part 21 with the side edge of the 1st wallpaper 91 produced by the cutting | disconnection.
After that, by attaching the next wallpaper joint member 1 to the other side edge of the first wallpaper 91 that has already been constructed, the wallpaper joint member 1 is installed at the boundary between the adjacent wallpaper 91 and 92. 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. A structure can be obtained.

  Furthermore, after the construction, there is a case where one wall paper joint member 1 or one wall paper 91 is desired to be exchanged due to damage to the wallpaper joint member 1 or partial contamination of the wallpaper 91. When replacing the conventional cloth joint member 1, it is necessary to peel off at least the two wall papers abutted therewith. However, according to the wall joint member 1 of the present invention, the surface 3b of the sticking part 3 is applied. The wallpaper joint member 1 can be removed simply by peeling off the pasted 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 left-right symmetric, 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.

[Second Embodiment]
Hereinafter, in description of 2nd-6th embodiment, description is abbreviate | omitted about a common structure, an effect, and a usage method, and a term and a code | symbol are used as it is.
As shown in FIG. 5, the wallpaper joint member 1 according to the second embodiment includes a standing part 2 and a sticking part 3 extending from one side of the standing part 2. The standing portion 2 includes a first side wall 211 including the first side surface portion 21, a second side wall 221 including the second side surface portion 22, a surface wall 231 including the surface portion 23, and a back surface including the back surface portion 24. Wall 241. These four walls are continuously connected so that the outer periphery thereof is annular, and forms an annular shape in cross section. The standing portion 2 further includes a hollow portion 25 surrounded by these four walls and continuously formed in the longitudinal direction.
The cross section of the hollow portion 25 has a substantially line-symmetric shape with reference to an imaginary line X passing through the center of the front surface portion 23 in the width direction and perpendicular to the back surface portion 24. However, the cross-sectional view shape of the hollow portion 25 is not limited to the substantially line symmetry as described above.

In this embodiment, since the hollow part 25 exists inside the standing part 2, the formation material of the wallpaper joint member 1 can be saved, and the wallpaper joint member 1 can be reduced in weight. Moreover, since the 1st side wall 211, the surface wall 231, the 2nd side wall 221 and the back surface wall 241 are cyclic | annular, even when it presses from on the standing part 2, the standing part 2 is hard to bend. , Stress is hard to concentrate on a part. For this reason, the joint material 1 for wallpaper of this invention can be cut | disconnected favorably using scissors, a cutter, etc.
In particular, since the hollow portion 25 has a substantially line-symmetric shape with respect to the imaginary line, stress during pressing is applied to the first side wall 211 and the second side wall 221 substantially evenly. Is hard to collapse.

Specifically, as shown in FIG. 5, the cross section of the hollow portion 25 has a rectangular shape that is substantially line symmetric with respect to the virtual line X.
For example, the width B1 of the first side wall 211 and the width B2 of the second side wall 221 are 0.5 mm to 2 mm, respectively, and the wall thickness A1 of the front wall 231 and the wall thickness A2 of the back wall 241 are 0. The height A3 of the hollow portion 25 is 0.5 mm to 4 mm, and the width B3 of the hollow portion 25 is 2 mm to 4 mm. The dimensions of each wall may be the same or different.
In the present embodiment, the width W2 of the standing portion 2 is equal to the sum of B1, B2, and B3, and is equal to the height H2 of the first side surface portion 21 (first side wall 211) and the proximal end of the pasting portion 3. The sum of the wall thickness T3 is equal to the sum of A1, A2, and A3.
Therefore, the width W2 (B1 + B2 + B3) of the standing portion 2 is 3 mm to 8 mm, preferably 3 mm to 6 mm. Moreover, the height (A1 + A2 + A3 = H2 + T3) of the standing portion 2 is 1.5 mm to 8 mm, and preferably 1.5 mm to 4 mm.
Moreover, in this embodiment, it is preferable that the standing part 2 further satisfies the following general formula (1) in the dimension of each wall.
General formula (1): B3 ≦ 3 × (B1 + B2) ≦ 3 × B3

However, when the width of the first side wall 211, the width of the second side wall 221, the thickness of the front wall 231, the thickness of the back wall 241, the width of the hollow portion 25, and the height of the hollow portion 25 are not constant ( For example, when the width and thickness change as in the modification described later), the width B1 of the first side wall 211, the width B2 of the second side wall 221, the thickness A1 of the front wall 231 and the back wall 241. The wall thickness A2 means the minimum value, and the width B3 of the hollow portion 25 and the height A3 of the hollow portion 25 mean the maximum value.
That is, the width B1 of the first side wall 211 means the shortest distance from the first side surface portion to the hollow portion 25. The same applies to the width B2 of the second side wall 221, the thickness A1 of the front wall 231 and the thickness A2 of the back wall 241. Moreover, the width B3 of the hollow part 25 and the height A3 of the hollow part 25 mean the length of the longest part from the front to the back in the cross section.

  When the dimensions of each wall satisfy the above numerical range and the general formula (1), the rigidity of the standing portion 2 is sufficiently secured, and the stress at the time of pressing is distributed substantially evenly. Therefore, even if it presses with blades, such as scissors and a cutter, the standing part 2 is hard to be crushed and the joint material member 1 for wallpaper can be cut | disconnected favorably.

  Preferably, the width B1 of the first side wall 211 and the width B2 of the second side wall 221 are the same length. In this case, since the entire upright portion 2 has a substantially line-symmetric shape with respect to the virtual line X, the overall rigidity of the upright portion 2 can be made substantially even.

[Modification of Second Embodiment]
In addition, in FIG. 5, although the cross section of the hollow part 25 is represented by the rectangular shape, a cross-sectional shape is not limited to a rectangular shape, Circular shape as represented to Fig.6 (a) may be sufficient. The cross-sectional shape is an ellipse as shown in FIG. 6B, a hexagon as shown in FIG. 6C, a trapezoid as shown in FIG. 11B, and other polygonal shapes. (Not shown).
Whatever the cross-sectional shape of the hollow portion 25 is, if it is substantially line symmetric with respect to the imaginary line X, the stress at the time of pressing is distributed substantially evenly on the first side wall 211 and the second side wall 221. it can.

  Further, in the modification shown in FIG. 7, the surface portion 23 is formed to be an arcuate surface that swells most forward in the virtual line X passing through the center in the width direction. Moreover, although the cross section of the hollow part 25 is substantially rectangular shape, it is formed so that the upper side may become arc shape which swells ahead. The upper side is formed so as to swell forward most at the center in the width direction of the surface portion 23.

[Third Embodiment]
As in the second embodiment, the standing portion 2 of the wallpaper joint member 1 according to the third embodiment includes a first side wall 211, a second side wall 221, a front wall 231, a back wall 241, and the like. A hollow portion 25 surrounded by four walls and continuously formed in the longitudinal direction.
In the present embodiment, the hollow portion 25 is partitioned into two or more hollow sections by the column portion 26. Similarly to the hollow portion 25, the column portion 26 is also formed continuously in the longitudinal direction of the standing portion 2.
For example, as shown in FIG. 8, the hollow portion 25 is partitioned into a first hollow section 251 and a second hollow section 252 by a single column portion 26.

  Since the joint member 1 for wallpaper of this embodiment is provided with the at least 1 pillar part 26 in the hollow part 25, even when pressed by blades, such as scissors and a cutter, the hollow part 25 (hollow division) The shape is difficult to deform (that is, the standing portion 2 is difficult to bend), and sufficient rigidity can be ensured. Therefore, the standing portion 2 is not easily crushed and the wallpaper joint member 1 can be cut well.

  For example, the width B1 of the first side wall 211, the width B2 of the second side wall 221 and the width B4 of the column part 26 are 0.5 mm to 2 mm, respectively. Further, the thickness A1 of the front wall 23 and the thickness A2 of the back wall 24 are 0.5 mm to 2 mm, respectively, and the height A4 of the first hollow section 251 and the second hollow section 252 is 0.5 mm to 0.5 mm, respectively. 4 mm. Furthermore, the width W2 of the standing portion 2 is 7 mm to 15 mm.
