Description

The present invention relates to a finishing material pasting panel in which a finishing material is pasted on the panel surface such as an outer wall and a partition wall, and a method for manufacturing the finishing material pasting panel.

Conventionally, as a panel used for an outer wall, a partition wall, or the like, a finishing material pasting panel has been used in which various finishing materials such as tiles are pasted on the surface to enhance the design. For example, an extruded cement board is used as a panel base material, and a tile as a finishing material is attached to the surface of the extruded cement board, which is used as an outer wall material. In the following description, "tile" will be described as an example of "finishing material".

Generally, when tiles are attached to the smooth surface of extruded cement boards, adhesives that have flexibility to follow the expansion and contraction differences of the cured panel and tiles, such as thermal expansion, are used. Will be done. However, since the adhesive strength of tiles to the panel depends on the adhesive, if the adhesive strength of the adhesive is reduced by the differential movement caused by the temperature change over time or the influence of rainwater, the sticking holding power of the tile will also be reduced. .. Then, when the adhesive strength of the adhesive is lowered and the tile cannot withstand the weight and wind pressure, the tile may be peeled off. Therefore, in order to prevent the tiles from peeling off, regular percussion inspections are carried out, but since percussion inspections are required for each tile, it is very laborious to inspect all tiles on a regular basis. It requires time-consuming work.

Therefore, as a prior art of this kind, a tile in which dovetail-shaped protrusions are arranged in parallel on the surface of a building material board (molded cement board) and a dovetail-shaped groove that can be fitted to the dovetail-shaped protrusions is recessed on the back surface is used for this ant. In some cases, a hardened material is inserted into the gap between the mold protrusion and the dovetail groove and parallel to the surface of the building material plate (see, for example, Patent Document 1).

Further, as another prior art, a ridge is horizontally extended on the surface of the substrate, the upper protrusion of the back surface of the tile is hooked on the ridge, and the back surface of the tile is painted with the lower end surface of the ridge of the substrate. Some are fixed by curing the filler to be attached (see, for example, Patent Document 2). The prior art describes that the lower surface of the ridges of the substrate is filled with excess adhesive to provide a curved portion that increases the bonding area of the filler.

Further, as another prior art, an engaging groove having a side wall for engaging the groove portion on the back surface side of the tile is provided on at least one surface of the extruded panel, and the groove portion on the back surface side of the tile is engaged with the engaging groove. There is an attempt to prevent the tiles from peeling off by fitting (hanging) (see, for example, Patent Document 3).

However, in the case of Patent Document 1, there is no description about the relationship between the dovetail projection and the dovetail groove, and depending on these relationships, the tile pasting work becomes difficult. Moreover, since there is no description about what kind of curing material is used to attach the tile, it may be difficult to maintain a stable attached state for a long period of time after the tile is attached.

Further, in the case of Patent Document 2, since the upper protrusion on the back surface of the tile is hooked on the convex strip of the substrate and the lower portion is adhered, it is difficult to apply the tile when the tile is vertically stretched. Moreover, since the position is determined by hooking the tile, it is difficult to control the manufacturing accuracy.

Further, also in the case of Patent Document 3, since the groove portion of the tile is hooked on the engaging groove on the surface of the extruded panel for tile tensioning, the tile cannot be applied to the vertically stretched extrusion molded panel, and the horizontal extrusion is performed. Limited to molded panels. Moreover, since the position is determined by hooking the tile, it is difficult to control the manufacturing accuracy.

Therefore, an object of the present invention is to provide a finishing material pasting panel and a method for manufacturing a finishing material sticking panel, which can keep the tile attached to the panel material with an adhesive for a long period of time.

In order to achieve the above object, the finishing material pasting panel according to the present invention is a finishing material sticking panel for sticking a finishing material sticking surface to a panel material sticking surface, and is the panel material or the above. One of the finishing materials includes a plurality of rib portions arranged side by side on the sticking surface so as to extend in one direction at predetermined intervals, and the panel material or the other of the finishing materials is said on the sticking surface. The rib portion is provided with a groove portion formed in a size that can be fitted to the rib portion at an interval that does not interfere with the rib portion, and the rib portion has a cross section orthogonal to the extending direction, and the rib portion has a cross section of 55 degrees to the end portion on both side surfaces. Ri spread at an angle of 65 degrees, and the base is formed in a concave R-shape, the end portion has an inclined surface formed on the convex R shape, the groove in a cross section perpendicular to the extending direction, from the base on both sides Ri Semama at an angle of 55 to 65 degrees toward the end portion, the base portion is formed in a concave R-shape, the end portion has an inclined surface formed on the convex R shape The rib portion and the groove portion have a gap in a cross section orthogonal to the extending direction of the rib portion, which is opposed to each other in the width direction with respect to the width direction distance from the base portion to the end portion of the inclined surface of the rib portion. The panel material and the finishing material are formed by 1 to 2 times and 1 to 2 times the widthwise distance from the base portion to the end portion of the inclined surface of the groove portion, and the panel material and the finishing material are the rib portion and the said portion. JIS K7215 defines the hardness after curing, which is applied along the both inclined surfaces between the groove portion, filled in the space between the rib portion and the groove portion after the finishing material is attached, and cured. It is configured to be bonded with an adhesive of 75 to 90 with a durometer hardness of type A. "Matching" in this specification and the documents of the claims means fitting with a gap.

With this configuration, the adhesive applied to the inclined surface between the rib portion of the panel material and the groove portion of the finishing material is filled in the space between these inclined surfaces and hardened when the finishing material is attached, and the panel material is cured. And the finishing material is the fitting force of the hardened adhesive (the "fitting force" in this specification and the documents of the scope of the patent claim is the state in which the panel material and the finishing material are fitted and cured between them. It is possible to prevent the finishing material from peeling off from the panel material by being firmly bonded by the adhesive force.) And the adhesive force.

Further, it is possible to efficiently attach the finishing material so that the adhesive applied between the rib portion and the groove portion is filled in the space between the rib portion and the groove portion, and after the adhesive is cured, the rib portion and the rib portion are formed. The bonded state can be maintained by the adhesive cured in the space between the groove and the groove.

Further, the rib portion may have an adhesive holding portion that is recessed from the base portion of the inclined surface of the rib portion toward the panel material. With this configuration, the excess adhesive that is applied between the rib portion and the groove portion and fills the space between them is also filled in the adhesive holding portion, and the adhesive is applied when the finishing material is attached. However, it is possible to work efficiently by suppressing the amount of material that comes out from the periphery of the finishing material.

Further, the rib portion is composed of a pair of rib portions in which concave portions are formed in the central portion in the width direction of the rib portion and are arranged side by side, and the groove portion is formed in the central portion in the width direction of the groove portion. A ridge portion that penetrates into the ridge portion may be provided, and the finishing material may be positioned by bringing the tip end portion of the ridge portion into contact with the lower end portion of the ridge portion. With this configuration, when the rib portion and the groove portion are fitted, the ridge portion in the widthwise central portion of the groove portion enters the concave portion in the widthwise central portion of the rib portion, and the concave portion and the ridge portion are formed. By confirming the positional relationship of the ribs from the extending direction of the rib portion, it is possible to adjust the position of the finishing material and attach it to the panel material while confirming the attachment position of the finishing material. Moreover, since the adhesive filled between the rib portion and the groove portion does not enter between the concave portion and the ridge portion, stable confirmation can be made.

Further, the ridge portion and the concave portion may be set at a height at which a gap is formed between the rib portion and the groove portion in a state of being in contact with each other. With this configuration, when the finishing material is attached to the panel material, the excess adhesive filled in these gaps also flows into the gap between the rib portion and the groove portion, making it easy to attach the finishing material. It can be carried out.

Further, the panel material may have a rib portion on at least one surface, and the finishing material may be formed in a rectangular shape and may have the groove portion in the short side direction or the long side direction of the back surface. With this configuration, a common panel material can be used, and the groove portion of the rectangular finishing material can be used for vertical and horizontal tensioning.

Further, the panel material is an extruded cement plate, and a plurality of rib portions may be provided in parallel with the extrusion direction of the extruded cement plate. With this configuration, a plurality of rib portions can be integrally formed when the extruded cement plate as the panel material is formed, and the rib portions provided on the panel material can be easily formed.

On the other hand, the method for manufacturing a panel for attaching a finishing material according to the present invention is a method for manufacturing a panel for attaching a finishing material, wherein the surface for attaching the finishing material is attached to the surface for attaching the finishing material, and the panel material or the above. It is juxtaposed on one of the bonding surfaces of the finishing material so as to extend in one direction at predetermined intervals, and in a cross section orthogonal to the extending direction, 55 to 65 degrees from the base to the end on both side surfaces. Ri spread at an angle, and the base is formed in a concave R-shape, the ends and a plurality of ribs having an inclined surface formed on the convex R shape, said the other of the panel material or the finish It is formed in the extending direction of the rib part with a size that can be fitted to the rib part at an interval that does not interfere with the rib part, and in a cross section orthogonal to the extending direction, 55 degrees to 65 degrees from the base to the end on both side surfaces. Ri Semama at an angle, and the base is formed in a concave R-shape, the end portion has a groove having an inclined surface formed on the convex R shape, and said rib portion and the groove, The gap between the portions facing each other in the width direction in the cross section orthogonal to the extending direction of the rib portion is 1 to 2 times the width direction spacing from the base portion to the end portion of the inclined surface of the rib portion, and the groove portion. It is formed at 1 to 2 times the widthwise spacing from the base to the end of the inclined surface of the surface, and the hardness after curing is JIS K7215 along the inclined surface between the rib portion and the groove portion. By applying an adhesive of 75 to 90 with a type A durometer hardness specified in 1 and attaching the finishing material to the panel material, the space between the rib portion and the groove portion was filled and cured. The finishing material is bonded to the panel material with the adhesive.

In the following embodiment, the extruded cement plate (hereinafter, simply referred to as “panel”) will be described as an example of the panel material 10, and the rectangular tile 30 will be described as an example of the finishing material. Further, a configuration in which the panel material 10 is provided with the rib portion 11 and the tile 30 is provided with the groove portion 31 will be described as an example. The concepts of the vertical direction and the width direction in this specification and the documents of the claims shall be consistent with the concepts of the vertical direction and the width direction in the state facing the panel material 10 shown in FIG.

[First Embodiment]
FIG. 1 is an enlarged end view of a partially enlarged joint portion of the finishing material pasting panel 1 according to the first embodiment. As shown in the figure, the panel material 10 according to the first embodiment is provided with a rib portion 11 (convex portion) so as to extend in the extrusion direction (one direction toward the paper surface) of the surface (one side). When the panel material 10 is an extruded cement plate, it is possible to easily integrally form the plurality of rib portions 11 in parallel when forming the extruded cement plate. The panel material 10 is not limited as long as the rib portion 11 can be integrally provided in addition to the extruded cement plate. For example, lightweight aerated concrete, precast concrete panel, metal panel and the like can be used.

The tile 30 to be attached to the panel material 10 is a tile 30 (FIG. 11) formed in a rectangular shape, and the back surface 32, which is the attachment surface, is in the direction toward the paper surface of the tile 30 (long side direction or short side direction). ) Is provided with a groove portion 31 extending to). The groove portion 31 has a gap C that does not interfere with the rib portion 11, and is formed in a width direction dimension that allows fitting with the rib portion 11. As the tile (finishing material) 30, in addition to ceramic and porcelain tiles, natural or artificial stone, wood, resin, and other tiles that can form the groove 31 can be used. The rib portion 11 of the panel material 10 and the groove portion 31 of the tile 30 are provided so as to extend in the direction toward the paper surface.

The rib portion 11 of the panel material 10 is formed in a trapezoidal cross section that gradually expands from the surface (attachment surface) 12 in a cross section (the surface shown in the drawing) orthogonal to the extending direction. Further, the groove portion 31 of the tile 30 is formed in a trapezoidal cross section that is recessed so as to gradually expand from the back surface (attachment surface) 32 in a cross section (the surface shown in the drawing) orthogonal to the extending direction. Therefore, the rib portion 11 has both side surfaces in the width direction formed on the inclined surface 15 extending from the base portion 13 (the surface 12 of the panel material 10) toward the end portion 14, and the groove portion 31 has both side surfaces in the width direction as the base portion 33. It is formed on an inclined surface 35 that narrows toward the end portion 34 (the back surface 32 of the tile 30). As shown in the present specification and claims, the "side surface" refers to an end face in the width direction in a cross section orthogonal to the direction in which the rib portion 11 extends.

As a result, in a state where the groove portion 31 of the tile 30 is fitted and attached to the rib portion 11 of the panel material 10, the inclined surface 15 of the rib portion 11 and the inclined surface 35 of the groove portion 31 face each other. The angle θ between the inclined surface 15 of the opposing rib portions 11 and the inclined surface 35 of the groove portion 31 is preferably 55 degrees to 65 degrees with respect to the front surface 12 of the panel material 10 (the back surface 32 of the tile 30). If it is smaller than 55 degrees, the tip of the rib portion 11 has an acute angle and is easily damaged. When it is larger than 65 degrees, the wedge effect with the adhesive 50 (FIG. 2) (the effect of curing in the wedge state and maintaining the bonded state) becomes small. In this embodiment, the inclined surface 15 of the rib portion 11 and the inclined surface 35 of the groove portion 31 have the same angle so as to be parallel to each other at the time of fitting.

The widthwise dimension of the rib portion 11 of the panel material 10 and the groove portion 31 of the tile 30 is a gap C in the width direction that does not interfere with the rib portion 11 when the groove portion 31 of the tile 30 is fitted to the rib portion 11 of the panel material 10. Is set to a size that has. As shown in the figure, the gap C between the end portion 14 of the rib portion 11 and the end portion 34 of the groove portion 31 is 1 to 1 with respect to the widthwise distance B between the base portion 13 and the end portion 14 of the inclined surface 15 of the rib portion 11. It is doubled, and it is also doubled with respect to the widthwise distance D between the base portion 33 and the end portion 34 of the inclined surface 35 of the groove portion 31.

If the gap C in the width direction is smaller than 1 times the spacing B (spacing D), the clearance (movable range of tile position adjustment) at the time of pasting the tile 30 becomes small, and the position adjustment of the tile 30 becomes difficult. Further, when it is larger than twice, the amount of the adhesive 50 (FIG. 2) used increases and the wedge effect due to the cured fitting becomes small. In this figure, the interval D is narrower than the interval B because the end portion 14 of the rib portion 11 is chamfered, but the interval B may be the same as the interval D before chamfering.

The size of the space A formed between the rib portion 11 of the panel material 10 and the groove portion 31 of the tile 30 due to the gaps B and D and the gap C is such that when the tile 30 and the panel material 10 are fitted, the size of the space A is determined. The adhesive 50 (FIG. 2) filled in the space A is set to a size that can secure sufficient bonding strength after curing.

FIG. 2 is an end view showing a joint portion of the finishing material pasting panel 1 shown in FIG. As shown in FIG. 1, a gap C in the width direction is provided between the rib portion 11 and the groove portion 31, and the intervals B and D are set on the inclined surfaces 15 and 35, respectively. Therefore, by fitting the groove portion 31 of the tile 30 in a state where the adhesive 50 is applied (beaded) along the inclined surface 15 of the rib portion 11, the adhesive 50 is placed between the rib portion 11 and the groove portion 31. The space A is filled and the tile 30 can be attached to the panel material 10.

The amount of the adhesive 50 applied is 2 to 3 times the amount of the space A (cross-sectional area) formed between the rib portion 11 and the groove portion 31. When the amount of the adhesive 50 is less than twice, the filling property of the adhesive 50 is deteriorated and the fitting force and the adhesive force are lowered. If it is larger than 3 times, the amount of protrusion when the tile 30 is attached increases, and it takes time and effort to remove the adhesive 50, resulting in a decrease in work efficiency.

Further, as the adhesive 50, it is made difficult to be deformed after curing so that the cured adhesive 50 is cured in a wedge state and exerts a fitting force. Specifically, the hardness of the adhesive 50 after curing is determined by the durometer hardness tester, as it is difficult to deform after curing and can be cured in a rusty state after curing to maintain a bonded state and obtain a fitting force. Hardness of (A type: for plastic / rubber) of 75 to 90 is used. The hardness of the adhesive 50 after curing is based on the plastic durometer hardness test method of "JIS K7215". As the adhesive 50, a modified silicon / epoxy resin adhesive, an epoxy resin adhesive, or the like having a hardness of 75 to 90 after curing can be used.

Then, the panel material 10 and the tile 30 bonded by using such an adhesive 50 were cured by filling the cured adhesive 50 between the rib portion 11 and the groove portion 31 after the adhesive 50 was cured. The state is reached, and the adhesive 50 can maintain the bonded state between the panel material 10 and the tile 30. That is, the adhesive 50 filled between the inclined surfaces 15 and 35 due to the shape in which the inclined surface 15 is provided in the rib portion 11 of the panel material 10 and the shape in which the inclined surface 35 is provided in the groove portion 31 of the tile 30. In addition to the adhesive force due to the above, the adhesive 50 can be cured to generate a fitting force for holding the groove portion 31 with respect to the rib portion 11. Then, by these forces, the tile 30 can be maintained in a state of being bonded to the panel material 10 with a small amount of adhesive material.

Further, as in the modified example of the finishing material pasting panel 1 shown in FIG. 3, the protruding height of the rib portion 11 of the panel material 10 and the recessed depth of the groove portion 31 of the tile 30 make the tile 30 the panel material 10. The back surface (attachment surface) 32 of the tile 30 may be brought into close contact with the front surface (attachment surface) 12 of the panel material 10 in a state of being attached to the tile 30. When the front surface 12 of the panel material 10 and the back surface 32 of the tile 30 are in close contact with each other, the adhesive 50 does not escape from these gaps, so that the adhesive 50 is filled to the details of the space A. .. Further, when the front surface 12 of the panel material 10 and the back surface 32 of the tile 30 are in close contact with each other, and the top of the rib portion 11 of the panel material 10 and the groove portion 31 of the tile 30 are in close contact with each other (FIG. 3), between them. Since there is no escape of the adhesive 50 to the space A, it is possible to fill the space A with the minimum amount of the adhesive 50 required.

These may be set in combination as appropriate, but considering the filling and protrusion of the adhesive 50, the configuration in which the front surface (sticking surface) 12 of the panel material 10 and the back surface (sticking surface) 32 of the tile 30 are in close contact with each other. Alternatively, it is desirable that the top of the rib portion 11 of the panel material 10 and the groove portion 31 of the tile 30 and both the front surface 12 of the panel material 10 and the back surface 32 of the tile 30 are in close contact with each other.

As described above, according to the finishing material pasting panel 1, a predetermined amount of the adhesive 50 is applied between the rib portion 11 of the panel material 10 and the groove portion 31 of the tile 30, and they are simply fitted. A strong bond between the panel material 10 and the tile 30 can be maintained for a long period of time with a smaller amount of adhesive than in the past.

FIG. 4 is an end drawing of the finished lumber pasting panel 1 in the bonded state shown in FIG. As shown in the figure, the panel material 10 is provided with a plurality of rib portions 11 in parallel at predetermined intervals so as to extend in the extrusion direction of the surface. In the finishing material pasting panel 1, the two groove portions 31 provided in the tile 30 are fitted and pasted to the two rib portions 11 arranged side by side in the panel material 10, and the tile 30 is laterally attached. It is tense.

When the tile 30 is attached to the panel material 10, the adhesive 50 is applied in a bead shape (linear shape) to the inclined surface 15 of the rib portion 11 of the panel material 10, and the groove portion 31 of the tile 30 is fitted to the rib portion 11. .. As a result, the adhesive 50 is filled in the space A between the rib portion 11 and the groove portion 31. Then, when the adhesive 50 is completely cured in the space A, the tile 30 can be firmly bonded to the panel material 10 so as to be integrated with the panel material 10. Moreover, with the minimum amount of adhesive for the space A, after the adhesive 50 is cured, the cured adhesive 50 can be bonded in the space A in a rusty state.

Further, since a mechanical casting gun such as a caulking gun can be used for the work of applying the adhesive 50, the work efficiency is improved as compared with the case of applying the adhesive 50 to the entire surface of the panel material 10 with a spatula or a trowel, and the adhesive is adhered. It is also possible to reduce the amount of loss of the agent 50. Further, since the coating area of the adhesive 50 is only the space A between the rib portion 11 and the groove portion 31, the position of the tile 30 can be easily adjusted after the tile 30 is attached. Moreover, since the amount of protrusion of the adhesive 50 due to the position adjustment of the tile 30 is smaller than that of the entire surface coating, the excess adhesive 50 can be suppressed, and the workability at the time of sticking is also improved in this respect.

As described above, according to the finishing material pasting panel 1, the groove portion 31 of the tile 30 and the rib portion 11 of the panel material 10 are bonded by using an appropriate amount of the adhesive 50 having a hardness of 75 to 90. When the tile 30 is pasted, the position of the tile 30 can be easily adjusted. After the high-hardness adhesive 50 is cured, the panel material 10 and the tile 30 are subjected to the fitting force and the adhesive force of the cured adhesive 50 between the rib portion 11 of the panel material 10 and the groove portion 31 of the tile 30. The bonded state with can be maintained for a long period of time. Moreover, this bonded state can be maintained until the adhesive 50 having a high hardness coagulates and breaks, as described with reference to FIG. 9, while the adhesive force is sufficiently functioning. Further, when the adhesive strength of the adhesive 50 having a high hardness is lowered, it can be held by the fitting force of the cured adhesive 50.

It is formed on an inclined surface 25 extending from the surface 22) side toward the end portion 24.

Further, in this embodiment, the adhesive holding portion 29 is provided so as to be recessed from the surface 22 of the panel material 20 in the width direction outward from the base portion 23 of the inclined surface 25. The adhesive holding portion 29 is a portion filled with a surplus of the adhesive 50 (FIG. 6) as described later. The adhesive holding portion 29 is formed so as to be recessed from the surface 22 of the panel material 20 so as to be connected from the space A formed between the rib portion 21 of the panel material 20 and the groove portion 41 of the tile 40. The adhesive holding portion 29 is also provided along the rib portion 21 so as to extend in one direction toward the paper surface.

Also in this embodiment, when the panel material 20 is an extruded cement plate, it is possible to easily integrally form the plurality of rib portions 21 in parallel at the time of forming the extruded cement plate. The material of the panel material 20 is not limited as long as the rib portion 21 can be integrally provided in addition to the extruded cement plate as in the first embodiment.

The tile 40 of this embodiment to be attached to the panel material 20 is a tile 40 (FIG. 11) formed in a rectangular shape, and the back surface 42, which is the attachment surface, is in the direction toward the paper surface (long side direction) of the tile 40. Alternatively, a groove 41 extending in the short side direction) is provided. The groove portion 41 has a gap C that does not interfere with the rib portion 21, and is formed in a width direction dimension that allows fitting with the rib portion 21. Then, in this embodiment, a ridge portion 46 that enters the concave portion 26 of the panel material 20 is provided at the central portion in the width direction of the groove portion 31. Therefore, each groove portion 31 is formed in a groove portion 31 in which two groove portions 31 are paired by the protrusion portion 46.

The width direction dimension of the ridge portion 46 is smaller than the width direction dimension of the concave portion 26, and the amount of protrusion that abuts on the positioning protrusion 27 formed in the central portion of the concave portion 26 in an appropriate pasted state. Is set to. In this example, the height is the same as the back surface 42 of the tile 40. By bringing the tip end portion of the ridge portion 46 into contact with the positioning protrusion 27 provided at the lower end portion of the concave portion 26, the back surface 32 of the tile 40 is attached to an appropriate position on the front surface 22 of the panel material 20. Can be confirmed. As the tile (finishing material) 40, any material may be used as in the first embodiment, and the groove portion 41 and the ridge portion 46 (which may be the opposite of the rib portion 21 and the concave portion 26) can be formed. Anything is fine.

The rib portion 21 of the panel material 20 has an inclined surface whose both side surfaces in the width direction extend from the base portion 23 (surface 22 of the panel material 20) side toward the end portion 24 in a cross section (the surface shown) orthogonal to the extending direction. It is formed at 25. Further, the groove portion 41 of the tile 40 is formed on an inclined surface 45 whose both side surfaces in the width direction are narrowed from the base portion 43 toward the end portion 44 (the back surface 42 of the tile 40) in a cross section (the surface shown) orthogonal to the extending direction. Has been done.

The angle θ of these inclined surfaces 25 and 45 with respect to the front surface 22 (back surface 42 of the tile 40) of the panel material 20 is preferably an angle of 55 degrees to 65 degrees. Further, the gap C between the rib portion 21 and the groove portion 41, the widthwise distance B between the base portion 23 and the end portion 24 of the inclined surface 25 of the rib portion 21, and the width between the base portion 43 and the end portion 44 of the inclined surface 45 of the groove portion 41. As for the relationship of the direction spacing D, the gap C in the width direction is preferably 1 to 2 times as large as the width direction spacing B and the width direction spacing D. Since this point is the same as that of the first embodiment described above, detailed description thereof will be omitted.

Therefore, when the groove 41 of the tile 40 is fitted to the rib portion 21 of the panel material 20, the groove portion 41 can be fitted without interfering with the rib portion 21, and the tile 40 is attached to the panel material 20. Then, the inclined surface 25 of the rib portion 21 and the inclined surface 45 of the groove portion 41 are attached in a facing state.

Further, in this embodiment, the ridge portion 46 provided in the widthwise central portion of the groove portion 41 abuts on the positioning protrusion 27 of the concave portion 26 provided in the widthwise central portion of the rib portion 21. It has become. Since the positioning protrusion 27 is formed to have a smaller width direction than the ridge portion 46, the positional relationship of the ridge portion 46 with respect to the positioning protrusion 27 in a state where the ridge portion 46 is in contact with the positioning protrusion 27. Is viewed from the extending direction of the rib portion 21, and the misalignment of the tile 40 can be confirmed.

Moreover, since the adhesive 50 does not enter the portions of the positioning protrusion 27 and the ridge portion 46, the state in which the ridge portion 46 is in contact with the positioning protrusion 27 can be confirmed regardless of the protrusion of the adhesive 50. By adjusting the position of the ridge portion 46 with respect to the positioning protrusion 27, the tile 40 can be easily attached while adjusting the position.

FIG. 6 is an end view showing a joint portion of the finishing material pasting panel 2 shown in FIG. As shown in FIG. 5, a gap C in the width direction is provided between the rib portion 21 and the groove portion 41, and the intervals B and D are set on the inclined surfaces 25 and 45, respectively. Therefore, the adhesive 50 is applied between the rib portion 21 and the groove portion 41 by fitting the groove portion 41 of the tile 40 in a state where the adhesive 50 is applied (beaded) along the inclined surface 25 of the rib portion 21. The space A is filled and the tile 40 can be attached to the panel material 20.

Moreover, in this embodiment, since the adhesive holding portion 29 is provided at the base portion 23 of the rib portion 21, the surplus portion of the adhesive 50 applied along the rib portion 21 and filled in the space A is this adhesive. The agent holding portion 29 is also filled. As a result, after the adhesive 50 filled in a wide range including the adhesive holding portion 29 in addition to the adhesive 50 filled in the space A between the panel material 20 and the tile 40 is cured in a rusty state, the tile 40 can be held firmly.

Further, by bringing the ridge portion 46 into contact with the positioning protrusion 27 of the ridge portion 26 provided between the rib portions 21, the ridge portion 46 is irrespective of the adhesive 50 protruding from the periphery of the tile 40. The position of the tile 40 can be easily adjusted by confirming the positional relationship between the tile 40 and the positioning protrusion 27.

That is, when the adhesive 50 protrudes from both ends of the tile 40, the end faces of the tile 40 are soiled with the adhesive 50, so that it is difficult to grasp the sticking state of the tile 40 to the panel material 20. However, since the adhesive 50 that has protruded does not enter between the concave portion 26 between the rib portion 21 of the panel material 20 and the ridge portion 46 at the central portion of the tile 40, the concave portion 26 and the ridge portion By confirming the positional relationship with the 46 and the state of close contact with the tile 40, it can be confirmed that the tile 40 is attached to an appropriate position of the panel material 20, and the position of the tile 40 can be easily adjusted. Moreover, the position adjustment of the tile 40 becomes easy and the workability is improved.

Further, as in the modified example of the finishing material pasting panel 2 shown in FIG. 7, the protruding height of the rib portion 21 of the panel material 20 and the recessed depth of the groove portion 41 of the tile 40 make the tile 40 the panel material 20. The groove portion 41 of the tile 40 may be brought into close contact with the top of the rib portion 21 of the panel material 20 in a state of being attached to the tile 40. In this figure, a protruding portion is provided from the groove portion 41 toward the rib portion 21, but the entire groove portion 41 may be formed to a depth that is in close contact with the rib portion 21. When the front surface 22 of the panel material 20 and the back surface 42 of the tile 40 are in close contact with each other, the adhesive 50 does not escape from these gaps, so that the adhesive 50 is filled to the details of the space A. .. Further, when the front surface 22 of the panel material 20 and the back surface 42 of the tile 40 are in close contact with each other, and the top of the rib portion 21 of the panel material 20 and the groove portion 41 of the tile 40 are in close contact with each other (FIG. 7), between them. Since there is no escape of the adhesive 50 to the space A, it is possible to fill the space A with the minimum amount of the adhesive 50 required.

These may be set in combination as appropriate, but considering the filling and protrusion of the adhesive 50, the front surface (sticking surface) 22 of the panel material 20 and the back surface (sticking surface) 42 of the tile 40 are in close contact with each other. Alternatively, it is desirable that the top of the rib portion 21 of the panel material 20 and the groove portion 41 of the tile 40, and both the front surface 22 of the panel material 20 and the back surface 42 of the tile 40 are in close contact with each other.

As described above, even with the finishing material pasting panel 2, the sticking holding force of the tile 40 can be firmly bonded by the two elements of the adhesive force of the adhesive 50 and the fitting force cured in a wedge state. Become. Therefore, even if the adhesive strength of the adhesive 50 is reduced, the tile 40 can be kept fixed to the panel material 20 by the fitting force of the adhesive 50 cured in the wedge state.

FIG. 8 is an end drawing of the finished lumber pasting panel 2 in the bonded state shown in FIG. As shown in the figure, the panel material 20 is provided with a plurality of rib portions 21 at predetermined intervals in parallel so as to extend in the extrusion direction of the surface. Then, in the finishing material pasting panel 2, the four (two pairs) groove portions 41 provided on the tile 40 are fitted and pasted on the four (two pairs) rib portions 21 arranged side by side on the panel material 20. The tile 40 is attached horizontally. When the tile 40 is attached to the panel material 20, the adhesive 50 is applied in a bead shape to the inclined surface 25 of the rib portion 21 of the panel material 20, and the groove portion 41 of the tile 40 is fitted to the rib portion 21.

As a result, the adhesive 50 is filled in the space A between the rib portion 21 and the groove portion 41, and the excess is also filled in the adhesive holding portion 29. Then, when the adhesive 50 is completely cured in the space A, the adhesive 50 is in a bonded state in which the adhesive 50 is cured in a rusty state from the space A to the adhesive holding portion 29, so that the tile 40 is integrated with the panel material 20. Can be firmly bonded.

Further, since a mechanical casting gun such as a caulking gun can be used for the work of applying the adhesive 50, the work efficiency is improved as compared with the case of applying the adhesive 50 to the entire surface of the panel material 20 with a spatula or a trowel, and the adhesive is adhered. It is also possible to reduce the amount of loss of the agent 50. Further, the coating area of the adhesive 50 is the space A between the rib portion 21 and the groove portion 41 and the portion of the adhesive holding portion 29, and the positioning protrusion 27 of the panel material 20 from which the adhesive 50 does not enter. Since the tile 40 can be pasted while confirming the positional relationship between the tile 40 and the ridge portion 46 of the tile 40, the position of the tile 40 can be easily adjusted at the time of pasting and after the pasting. Moreover, since the amount of protrusion of the adhesive 50 due to the position adjustment of the tile 40 is smaller than that of the entire surface coating, the excess adhesive 50 can be suppressed, and the workability at the time of pasting is also improved in this respect.

As described above, according to the finishing material pasting panel 2, the groove portion 41 of the tile 40 and the rib portion 21 of the panel material 20 are bonded by using an appropriate amount of the adhesive 50 having a hardness of 75 to 90. When the 40 is pasted, the position of the tile 40 can be easily adjusted. After the high-hardness adhesive 50 is cured, the panel material 20 and the tile 40 are subjected to the fitting force and the adhesive force of the cured adhesive 50 between the rib portion 21 of the panel material 20 and the groove portion 41 of the tile 40. It is possible to maintain a strong bond with and for a long period of time. Moreover, this bonded state can be maintained until the adhesive 50 having a high hardness coagulates and breaks, as described with reference to FIG. 9, while the adhesive force is sufficiently functioning. Further, even when the adhesive strength of the high hardness adhesive 50 is reduced, it can be held by the fitting force of the cured adhesive 50.

[Example of tile peeling]
FIG. 9 is a drawing showing a case where the tile 40 is peeled off in the finishing material pasting panel 2 in the second embodiment shown in FIG. According to the finishing material pasting panel 2, even if the adhesive force at the interface between the panel material 20 and the tile 40 is lost, the adhesive 50 that exists in the state of being cured and filled in the space A is itself. The volume does not change. Therefore, even if the adhesive strength of the adhesive is reduced, the tile 40 is not peeled off from the panel material 20 as long as the fitting force of the adhesive 50 has a proof stress equal to or higher than the weight of the tile 40 or the wind pressure. be able to. Therefore, as shown in the figure, the tile 40 attached to the panel material 20 is formed until the adhesive 50 is cohesively broken while the adhesive strength is sufficiently functioning, or when the adhesive strength of the adhesive 50 is reduced. However, the sticking state can be maintained for a long period of time due to the fitting force of the cured adhesive 50.

[Manufacturing method of finishing material pasting panel]

Let me paste it. As described above, according to the finishing material pasting panel 2, the adhesive 50 may be applied in a bead shape to the inclined surface 25 of the rib portion 21, so that, for example, the adhesive 50 is applied to the entire surface as in the conventional case. It is possible to reduce the amount of adhesive used by about 20% as compared with the case of applying.

FIG. 11 is a perspective view showing a state in which the tile 40 is attached after the adhesive 50 is applied to the rib portion 21 as shown in FIG. As shown in the figure, when the tile 40 is attached after the adhesive 50 is applied, the adhesive 50 has an inclined surface (FIG. 6) 25 of the rib portion 21 and an inclined surface (FIG. 6) 45 of the groove portion 41 as described above. It fills the portion of the space A between them, but does not penetrate to the portion between the concave portion 26 and the ridge portion 46 in the central portion. Therefore, by visually confirming how the ridge portion 46 of the tile 40 is in contact with the positioning protrusion 27 provided on the concave portion 26 of the panel material 20 from the extending direction of the rib portion 21, the tile 40 is formed. The finishing material pasting panel 2 can be manufactured by easily adjusting the sticking position.

[Summary]
As described above, according to the finishing material pasting panels 1 and 2, the space A between the rib portions 11 and 21 of the panel materials 10 and 20 and the groove portions 31 and 41 of the tiles (finishing materials) 30 and 40. Since the adhesive 50 filled in is completely cured in a rusty state and firmly bonded to each other, the panel materials 10 and 20 and the tiles (finishing materials) 30 and 40 are in a state of being fitted via the rusty adhesive 50. Therefore, even if the adhesive strength of the adhesive 50 is reduced, it is possible to prevent the tiles (finishing materials) 30 and 40 from peeling off from the panel materials 10 and 20 for a long period of time.

Further, by applying the adhesive 50 only along the side surfaces of the rib portions 11 and 21, sufficient tiles (finishing materials) 30 and 40 can be obtained by the adhesive force of the adhesive 50 and the fitting force due to the rust effect after curing. Since the holding force can be secured, the amount of the adhesive 50 used can be suppressed.

Further, the work efficiency is improved as compared with the case where the adhesive 50 is applied to the entire surface with a spatula or a trowel, the loss amount of the adhesive 50 can be reduced, and the adhesive area of the adhesive 50 is the rib portion 11,21. Since it is only on the side surface, the position can be easily adjusted when the tiles (finishing materials) 30 and 40 are attached. Moreover, since the excess adhesive 50 is not generated due to the position adjustment, the workability at the time of pasting is improved.

Further, by changing the direction of forming the groove portions 31 and 41 of the tiles (finishing materials) 30 and 40 in orthogonal directions, the tiles (finishing materials) 30 and 40 are vertically or horizontally stretched on the same panel material 10. Therefore, the tiles (finishing materials) 30 and 40 can be easily attached to the same panel material 10 in a desired direction.

In the above-described embodiment, the example in which the rib portions 11 and 21 are provided on the panel materials 10 and 20 and the groove portions 31 and 41 are provided on the tiles 30 and 40 has been described. However, the panel materials 10 and 20 and the tiles 30 and 40 have been described.
