Description

  The present invention relates to a panel mounting structure and a panel mounting method for a base such as an indoor wall, ceiling, floor, or outdoor wall.

  As the panel mounting structure described above, a structure has been proposed in which the panel is bonded to the base using a double-sided pressure-sensitive adhesive tape and an adhesive (see, for example, Patent Document 1). More specifically, a double-sided pressure-sensitive adhesive tape is attached along each side to the vicinity of the four sides of the panel, and a double-sided pressure-sensitive adhesive tape is attached along the longitudinal direction at the center of the panel, and surrounded by the double-sided pressure-sensitive adhesive tape. It has a structure in which adhesive is placed on the non-tape area and the panel is pressed against the base.

  By the way, when attaching a plurality of panels arranged side by side by the above structure, there is a problem that it is difficult to set the interval between the end portions of the adjacent panels. It is preferable in terms of appearance that the end portions of these panels are as close as possible, but when the end portions are brought close to each other, the end portions of the panels are brought into contact with each other due to thermal expansion of the panel, so that the end portions of the panel are lifted from the base. There is a risk that. Therefore, in the configuration described in Patent Document 1, a joint made of an elastic material is inserted between the end portions of the panels, and even if the end portions approach each other due to thermal expansion of the panel, the panel end portions do not float from the base. I am doing so.

  In order to prevent the panel edge from floating from the ground even when the panel edges are close to each other in this way, it can be handled by bonding the edge of the panel to the ground, but the amount of adhesive and the pressing force are not appropriate. In some cases, the adhesive tends to protrude outwardly between the ends, and the appearance of the adhesive is impaired by the protruding adhesive.

  In view of such circumstances, the present invention improves the appearance by bringing the end portions of a plurality of panels close to or in contact with each other, and lifts the end portions from the base due to thermal expansion of these panels. An object is to provide a panel mounting structure and a mounting method that can be prevented.

  As means for solving the above-mentioned problems, the present inventors suppress the lifting of the ends by joining the ends of the panels using an adhesive for attaching the panels to the base. I came up with the idea.

  Specifically, the panel mounting structure provided by the present invention includes a first panel and a second panel that are attached to the base in a state of being arranged along the base, and the first panel and the second panel are used as the base. An adhesive disposed between a back surface of each panel and the base so as to be bonded, and the first panel and the second panel have a first butted end and a second butted end that are butted against each other. Each of the first butted ends close to the base protrudes more toward the second butted end than the portion far from the base to form a first protrusion, and the second Of the butt end portion, a portion farther from the base protrudes toward the first butt end portion than a portion closer to the base to form a second protrusion, and the second protrusion is the second protrusion. The protrusion is the first protrusion of the first butting end. In a state where it is in contact with a part farther from the base than the part, the first projecting part is located between the tip of the first projecting part and the part of the second butting end part closer to the base than the second projecting part. And having a larger projection length than the first protrusion so as to form one adhesive entry path, and the first adhesive entry path between the second protrusion and the first protrusion. The adhesive protrudes from the first protrusion to the side opposite to the base so as to form a second adhesive entrance path that communicates with the adhesive, and the adhesive protrudes from the base to the first adhesive entrance path and the base The first protrusion and the second protrusion are bonded in the panel thickness direction by entering the second adhesive entry path. According to this structure, while the 2nd protrusion part in the 2nd butt end part of the 2nd panel approaches the site | part far from a base | substrate among the 1st butt end parts of the 1st panel, improving an external appearance It is possible to prevent the second protruding portion from being lifted. That is, according to this structure, the adhesive that contributes to the adhesion between the base and the panel enters the first adhesive entry path and further the second adhesive entry path, and the first protrusion of the first panel. In order to bond the second protrusions of the second panel, due to the thermal expansion of both panels, the second protrusions abut on the part of the first butting end of the first panel farther from the base. This prevents the second protrusion from being lifted up. Further, since the adhesive protruding from between the back surface of the panel and the base is received in the first and second adhesive entry paths on the back side of the second protrusion, the appearance of this adhesive protruding to the front side of the panel The above-mentioned effect can be obtained while avoiding the decrease of the above.

In this structure, the second protrusion that have a shape that the rear surface of the front end portion protrudes to the base side of the back surface of the base side portion than the distal portion. The protruding portion on the back surface effectively suppresses the adhesive that has entered the second adhesive entering path from further protruding outside the panel from the gap between the second protruding portion and the first butted end portion of the first panel. . Further, the one base side portion than the protruding portion of the distal end of the second protrusion, sufficient clearance (second adhesive entryway) the entry of the adhesive between the first projecting portion Can be secured.

In this structure, the adhesive tape is provided between each panel and the base and in the vicinity of the butt end portion so as to move the adhesive toward the adhesive reservoir. Also good. In such a case, when the adhesive is spread by narrowing the panel between the panel and the base by pressing the panel, the adhesive tape provided in the vicinity of the butt end portion changes the spreading direction of the adhesive. It is possible to regulate and move the adhesive toward the adhesive reservoir.
Moreover, in this structure, the gap dimension in the panel thickness direction in the second adhesive entry path between the base side portion and the first protrusion is equal to the protrusion length of the second protrusion. It may be constant in the direction.

Further, the panel attachment method provided by the present invention is a method for attaching the first panel and the second panel to the base in a state of being arranged along the base, and as the first panel and the second panel, Each has a first butting end portion and a second butting end portion that are butted against each other, and the portion of the first butting end portion closer to the base is the second portion than the portion farther from the base. A first projecting portion is formed by projecting toward the butting end, and a portion of the second butting end that is farther from the base projects closer to the first butting end than a portion closer to the base. Forming a second protrusion, the second protrusion being in a state in which the second protrusion is in contact with a portion of the first butting end that is farther from the base than the first protrusion. Of the tip of the first protrusion and the second butt end The second projecting portion has a projecting length larger than that of the first projecting portion so as to form a first adhesive entrance path between the second projecting portion and the portion closer to the base. projecting in a state apart on the side opposite to the base from the first protrusion to form a second adhesive entryway leading to said first adhesive entryway between the first projecting portion , While ensuring a gap in the second adhesive entrance path for allowing the adhesive to enter between the first projecting portion and the portion of the second projecting portion on the base side with respect to the tip end portion. The adhesive of the second protrusion is further prevented from sticking out of the outside of the panel from the gap between the second protrusion and the first butted end of the first panel. the back surface of the tip, to have a shape protruding on the base side from the rear surface of the base side portion panel And pressing the two panels against the base in a state where an adhesive is interposed between the base and the back surfaces of the first panel and the second panel. And adhering the first protrusion of the first panel and the second protrusion of the second panel in the panel thickness direction. It is a waste. According to the method of the present invention, the same effect as in the first aspect can be obtained.

  In the present invention, the second protrusion at the second butting end of the second panel is brought close to the portion of the first butting end of the first panel that is far from the base, thereby improving the appearance. However, it is possible to prevent the second protrusion from floating. That is, according to this structure, the adhesive that contributes to the adhesion between the base and the panel enters the first adhesive entry path and further the second adhesive entry path, and the first protrusion of the first panel. In order to bond the second protrusions of the second panel, due to the thermal expansion of both panels, the second protrusions abut on the part of the first butting end of the first panel farther from the base. This prevents the second protrusion from being lifted up. Further, since the adhesive protruding from between the back surface of the panel and the base is received in the first and second adhesive entry paths on the back side of the second protrusion, the appearance of this adhesive protruding to the front side of the panel The above-mentioned effect can be obtained while avoiding the decrease of the above.

It is the figure which looked at the panel mounting structure which concerns on one Embodiment of this invention from the bottom face side. It is a bottom view of a panel. It is explanatory drawing of the panel attachment method.

  Embodiments of the present invention will be specifically described below.

  FIG. 1 is a view of a panel mounting structure according to an embodiment of the present invention as viewed from the bottom side.

  In the panel mounting structure 1 according to the present embodiment, a plurality of panels 10, 10... Are mounted on the base 3 with the end portions abutted against each other via the adhesive 5 and the double-sided tape 7 between the base 3. Structure.

  As the adhesive 5, for example, Bond KU912 (Konishi Co., Ltd.), which is a moisture curable urethane adhesive, is used, and the viscosity is 70 to 170 Pa · s (20 r / min).

  In the present embodiment, the base 3 is an indoor wall standing on the floor surface, and a panel 10 is attached to the outer surface of the base 3.

  Each panel 10 has a rectangular plate shape and has the same configuration, and is arranged side by side so that its width direction W coincides with the outer surface of the base 3, and the first butt is formed on one side (right side) of the width direction W. It has an end 13 and a second butted end 15 on the other side (left side). The first butting end 13 has a portion closer to the base 3 with respect to a portion 17a far from the base 3 on the side of the panel 10 on the side along the surface of the base 3 and adjacent (right adjacent). A first projecting portion 17 is provided so as to project toward the second butting end portion 15 side (a portion 19a side described later), and the second butting end portion 15 has a base with respect to the portion 19a closer to the base 3. A second projecting portion in which a portion far from 3 is projected to the side of the portion 17a of the first butted end portion 13 of the adjacent panel 10 on the side (next left side) along the surface of the base 3. 19 is provided. The first protrusion 17 is disposed to face the part 19 a in the width direction W, and the second protrusion 19 is in contact with the part 17 a in the width direction W.

  Here, in the two central panels 10 in FIG. 1, the left panel 10 is referred to as a first panel 11, and the right panel 10 is referred to as a second panel 12.

  The second projecting portion 19 of the first panel 11 faces the first projecting portion 17 of the panel 10 (10A) on the left side of the first panel 11 in the panel thickness direction A and covers the first projecting portion 17. The first protrusion 17 of the panel 11 is covered with the second protrusion 19 so as to face the second protrusion 19 of the second panel 12 in the panel thickness direction A.

  The second projecting portion 19 of the second panel 12 faces the first projecting portion 17 of the first panel 11 in the panel thickness direction A and covers the first projecting portion 17, and the first projecting portion 17 of the second panel 12 is The second protrusion 19 is opposed to the second protrusion 19 of the panel 10 (10B) on the right side of the second panel 12 in the panel thickness direction A and is covered with the second protrusion 19.

  The projecting length L1 of the second projecting portion 19 of each panel 11, 12 is longer than the projecting length L2 of the first projecting portion 17, and this second projecting portion 19 is the butt end of the left panel 10. The portion 13 is in contact with the portion 17a. In this contact state, more specifically, between both butted end portions 13 and 15, more specifically, between the first projecting portion 17 of the left panel 10 and the portion 19 a of the right panel 10. A first adhesive entry path 21 is formed.

  The second projecting portion 19 has a distal end portion 23 near the left panel 10 and a proximal end portion 25 farther from the left panel 10 than the distal end portion 23, and the proximal end portion 25 is the first projecting portion. The first adhesive is formed between the back surface (lower surface) of the base end portion 25 and the front surface (upper surface) of the first projecting portion 17. A second adhesive entry path 27 communicating with the entry path 21 is formed. Further, a gap 29 through which the adhesive 5 is passed is formed between the back surface (lower surface) of the tip portion 23 and the surface (upper surface) of the first protrusion 17, and the gap 29 is formed by the second adhesive agent. It communicates with the approach path 27.

  In the second adhesive entry path 27, the adhesive 5 provided between the left and right panels 10 constituting the second adhesive entry path 27 and the base 3 is a first adhesive entry path. 21 is supplied. That is, the first and second adhesive entrance paths 21 and 27 have a function of receiving the protruding portion of the adhesive 5 on the back side of the second projecting portion 19. The adhesive that protrudes into the second adhesive entrance path 27 is mainly composed of an adhesive 5A provided between the right panel 10 and the base 3, but between the left panel 10 and the base 3. The adhesive 5 </ b> B provided in the above may be included. In the gap 29, when the adhesive 5 overflows into the second adhesive entry path 27 more than the amount accumulated in the second adhesive entry path 27, it can be accommodated in the second adhesive entry path 27. No adhesive 5 is supplied. The gap dimension B between the base end portion 25 and the first protrusion 17 sandwiching the second adhesive entry path 27 is larger than the dimension C in the panel thickness direction A of the gap 29, and the first adhesive entry It is set smaller than the dimension F in the width direction W of the path 21.

  In addition, between the panels 10 and the base 3 and on the inner side in the width direction W of the adhesives 5 (5A, 5B), the double-sided tape 7 is continuously along the longitudinal direction of the panel 10 and over the entire length. Is provided. The adhesive 5 (5A, 5B) is also provided continuously along the longitudinal direction of the panel 10 and over the entire length.

  FIG. 2 is a bottom view of the panel.

  The panel 10 is formed to have a constant thickness dimension T1 except for the first projecting portion 17 and the second projecting portion 19, and the gap dimension B is equal to the thickness dimension T4 of the first projecting portion 17 with respect to the base end portion 25. A value obtained by adding the thickness dimension T2 is set to a value obtained by subtracting the thickness dimension T1. For example, when T1 = 4 mm, T4 = 1.6 mm, and T2 = 1.6 mm, the gap dimension B is set to 0.8 mm. Further, the dimension C in the thickness direction A of the gap 29 is set to a value obtained by subtracting the thickness dimension T1 of the first projecting portion 17 from the thickness dimension T3 of the distal end portion 23 from the thickness dimension T1. For example, when T3 = 2.1 mm, the dimension C in the thickness direction A of the gap 29 is set to 0.3 mm. In addition, the value of the above dimensions T1-T4 is an example, and can select a different value suitably.

  The protrusion length L1 of the second protrusion 19 is set to be longer than the protrusion length L2 of the first protrusion 17, and the value obtained by subtracting L2 from L1 is the first adhesion in the width direction W. It corresponds to the dimension F of the agent entry path 21. For example, when the dimension F is L1 = 5.0 mm and L2 = 4.0 mm, the dimension F is set to 1.0 mm larger than the gap dimension B. In addition, about the dimension F, the gap | interval dimension B, and the dimension C, the 1st adhesive agent approach path 21, the 2nd adhesive agent approach path 27, and the clearance gap 29 are made into adhesive according to the kind and viscosity of the adhesive agent 5, for example. It is preferable that 5 is appropriately selected as a value that can move without hindrance. The length L3 of the base end portion 25 in the panel width direction W is set to about 3.5 mm when L1 = 5.0 mm, for example.

  Next, a panel mounting method for obtaining the panel mounting structure according to this embodiment configured as described above will be described with reference to FIG.

  First, a predetermined number of panels 10 to be attached to the wall are prepared.

  Next, as shown in FIG. 3A, the adhesive 5B is attached to the region D to which the first panel 11 of the base 3 is attached, and the double-sided tape 7 is adhered to the inner side in the width direction W from the adhesive 5B. Then, the adhesive 5A is attached to the region E to which the second panel 12 of the base 3 is attached, and the double-sided tape 7 is attached to the inner side in the width direction W than the adhesive 5A.

  Next, as shown in FIG. 3B, the first panel 11 is pressed and attached to the region 3 of the base 3 toward the base 3. At this time, the surface (upper surface) of the first protrusion 17 of the first panel 11 remains exposed, and one second protrusion 19 (not shown in the drawing) is attached before the first panel 11. The first protrusion 17 of the obtained panel 10 (10A in FIG. 1) is covered.

  Next, as shown in FIG. 3C, the second panel 12 is attached to the region 3 of the base 3 by pressing it against the base 3 side. At this time, the second projecting portion 19 of the second panel 12 is made to face the first projecting portion 17 of the first panel 11 attached earlier, and the second projecting portion 19 is made to face the butting end portion 13 of the first panel 11. The first adhesive entrance path 21 is formed between the both butted ends 13 and 15 in contact with the portion 17a.

  Next, the second panel 12 is pressed against the base side, and the adhesive 5 </ b> A between the base 3 and the second panel 12 passes through the first adhesive entrance path 21 and the second adhesive entrance path 27. Then, the adhesive 5 </ b> A is supplied to the gap 29, and the second panel 12 is stuck on the base 3. At this time, the double-sided tape 7 restricts the adhesive 5 </ b> A from spreading toward the double-sided tape 7, and the double-sided tape 7 works to move the adhesive 5 </ b> A to the second adhesive entry path 27. The first adhesive entrance path 21 and the second adhesive entrance path 27 include not only the adhesive 5A between the base 3 and the second panel 12, but also between the first panel 11 and the base 3. The adhesive 5B may also enter. In other words, the adhesive 5 does not harden until the attachment of the first panel 11 and the second panel 12 is completed, and enters the first adhesive entry path 21 and the second adhesive entry path 27. It is preferable to use one having a viscosity and a curing rate capable of being

  As a result, the second panel 12 is mounted on the base 3. The above process is repeated in the same manner in the subsequent panel mounting.

  Therefore, in the case of the present embodiment, the second projecting portion 19 at the second butting end 15 of the second panel 12 is located on the portion 17 a farther from the base 3 in the first butting end 13 of the first panel 11. It is possible to prevent the second protrusion 19 from being lifted up while improving the appearance by being close to each other. That is, the adhesive 5 that contributes to the adhesion between the base 3 and the panel 10 enters the first adhesive entry path 21 and further the second adhesive entry path 27 and enters the first protrusion 17 of the first panel 11. Part of the first butt end 13 of the first panel 11 farther from the base 3 due to the thermal expansion of both the panels 11 and 12 in order to bond the second projection 19 of the second panel 12 The second projecting portion 19 is prevented from being lifted by the second projecting portion 19 coming into contact with 17a. Further, since the adhesive 5 protruding from between the back surface of the panel 10 and the base 3 is received by the first and second adhesive entrance paths 21 and 27 on the back side of the second protrusion 19, the adhesive 5 However, the above-mentioned effect can be obtained while avoiding the deterioration of the appearance due to protruding to the front side of the panel.

  Moreover, in this embodiment, since the 2nd protrusion part 19 has the shape where the back surface of the front-end | tip part 23 protrudes in the base | substrate 3 side rather than the back surface of another site | part (base end part 25), this back surface The protruding portion 23a effectively inhibits the adhesive 5 that has entered the second adhesive entering path 27 from further protruding outside the panel from the contact portion H between the second protruding portion 19 and the portion 17a. Further, a portion (base end portion 25) on the base side of the protruding portion 23 a at the distal end of the second protruding portion 19 is sufficiently spaced from the first protruding portion 17 to allow the adhesive 5 to enter (the first end portion). 2 adhesive entry paths) 27 can be secured.

  In addition, in embodiment mentioned above, although the 2nd panel 12 is stuck after sticking the 1st panel 11, this invention is not restricted to this, Two sheets of the 1st panel 11 and the 2nd panel 12 May be pasted at the same time after temporary setting, or three or more panels may be pasted in the same manner.

  In the above-described embodiment, the second projecting portion 19 and the portion 17a are brought into contact with each other. However, the present invention is not limited to this, and there is a small gap between the second projecting portion 19 and the portion 17a. It may be in a close state, and even in this case, the same can be applied.

  Further, in the above-described embodiment, the double-sided tape is used to move the adhesive 5 toward the second adhesive entrance path 27 between the panel 10 and the base 3 and in the vicinity of the butted ends 13 and 15. However, the present invention is not limited to this, and instead of the double-sided tape 7, a tape with an adhesive film provided on one side or a tape with an adhesive film omitted is attached with an adhesive. May be used.

  Furthermore, in the embodiment described above, the adhesive 5 is continuously provided over the entire length in the longitudinal direction of the panel 10. However, the present invention is not limited to this, and the adhesive 5 may be provided intermittently along the longitudinal direction of the panel 10. Good.

  Furthermore, in the above-described embodiment, the case where a plurality of panels are arranged in the width direction has been described as an example. However, the present invention is not limited thereto, and in the case where a plurality of panels are arranged in the longitudinal direction. Can be similarly implemented. Furthermore, the present invention can be applied to a case where a plurality of panels are attached in both the width direction and the longitudinal direction.
