Description

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

BACKGROUND ART Conventionally, as a panel used for an outer wall, a partition wall, etc., a finishing material-attached panel in which various finishing materials such as tiles are attached to the surface to improve the design is used. 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 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 a tile is attached to the smooth surface of an extruded cement board, an adhesive that has flexibility is used to follow the expansion and contraction differences such as thermal expansion of the cured panel and tile. To be done. However, since the adhesive strength of the tile to the panel depends on the adhesive, if the adhesive strength of the adhesive decreases due to the differential movement caused by the temperature change over the years and the effects of rainwater, the adhesive strength of the tile will also decrease. .. When the adhesive strength of the adhesive is reduced and the tile cannot withstand the weight and wind pressure, the tile may be peeled off. Therefore, a percussion inspection is regularly performed to prevent the tiles from coming off, but since it is necessary to perform a percussion inspection for each tile, it is extremely labor intensive to perform an inspection for all tiles on a regular basis. And time-consuming work is required.

Therefore, as a prior art of this kind, a tile in which a dovetail-shaped projection is juxtaposed on the surface of a building material plate (molded cement board) and a dovetail-shaped groove that can be fitted into the dovetail-shaped projection is provided on the back surface There is one in which a hardening material is inserted in the gap between the mold protrusion and the dovetail groove and arranged in parallel on the surface of the building material plate (for example, see Patent Document 1).

Further, as another prior art, a ridge is horizontally extended on the surface of the substrate, the upper protrusion of the tile back surface is hooked on the ridge, and the back surface of the tile is coated with the lower end surface of the ridge of the substrate. There is also one that is fixed by hardening the filler to be deposited (for example, see Patent Document 2). In this prior art, it is described that the lower surface of the ridge of the substrate is provided with a curved portion that is filled with an excessive adhesive agent to increase the bonding area of the filler.

Further, as another prior art, at least one surface of the extruded panel is provided with an engaging groove having a side wall for engaging the groove portion on the rear surface side of the tile, and the groove portion on the rear surface side of the tile is engaged with this engaging groove. There is one that tries to prevent the tiles from coming off (locking) (see, for example, Patent Document 3).

Japanese Utility Model Publication No. 64-43123 Japanese Utility Model Publication No. 4-135643 JP-A-6-129071

However, in the case of the above-mentioned Patent Document 1, there is no description about the relationship between the dovetail-shaped projection and the dovetail-shaped groove, and depending on these relationships, the tile attaching work becomes difficult. Moreover, since what kind of curing material is used to attach the tile is not described, it may be difficult to maintain a stable attachment state for a long period of time after attaching the tile.

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

Further, in the case of Patent Document 3 as well, since the tile groove is hooked to the engaging groove on the surface of the extruded panel to perform tiling, it cannot be applied to the vertical extruded panel, and the horizontal extruded panel is used. Limited to molded panels. Moreover, since the position is determined by hooking the tiles, it is difficult to control the manufacturing accuracy.

Therefore, it is an object of the present invention to provide a finishing material sticking panel and a manufacturing method of the finishing material sticking panel, which can maintain a state where the tile is stuck to the panel material with an adhesive for a long period of time.

In order to achieve the above object, the finishing material sticking panel according to the present invention is a finishing material sticking panel for sticking the sticking surface of the finishing material to the sticking surface of the panel material, wherein the panel material or the One of the finishing materials is provided with a plurality of rib portions arranged side by side on the pasting surface so as to extend in one direction at predetermined intervals, and the other of the panel material or the finishing material is the above-mentioned pasting surface on the pasting surface. The groove portion is formed to have a size such that it can be fitted with the rib portion at an interval that does not interfere with the rib portion. In the cross section orthogonal to the extending direction, the groove portion has inclined surfaces on both side surfaces that narrow toward the end portion from the base portion, the panel material and the finishing material, between the rib portion and the groove portion. An adhesive having a hardness of 75 to 90 in terms of durometer after curing, which is applied along both the inclined surfaces between and is 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 drug bound. The term "fitting" in this specification and the documents in the claims means fitting in a state 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 the inclined surfaces when the finishing material is attached and cured, and the panel material And the finishing material is the mating force of the cured adhesive ("fitting force" in this specification and the documents of the claims means that the panel material and the finishing material are mated with each other 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 strength) and the adhesive strength.

Further, between the rib portion and the groove portion, a gap between facing portions in a width direction in a cross section orthogonal to a direction in which the rib portion extends is with respect to a width direction interval from a base portion to an end portion of an inclined surface of the rib portion. The width may be 1 to 2 times, and may be 1 to 2 times the widthwise interval from the base to the end with the inclined surface of the groove. According to this structure, 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. Can be kept bonded by the adhesive that has hardened in the space between the rib 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. According to this structure, a surplus of the adhesive applied between the rib portion and the groove portion and filling the space between the rib portion and the groove portion is also filled in the adhesive holding portion, and the adhesive agent is applied when the finishing material is attached. It is possible to perform work efficiently by suppressing the amount of slag that comes out of the periphery of the finishing material.

Further, the rib portion is configured as a pair of rib portions in which a concave streak portion is formed in a center portion in the width direction of the rib portion and arranged in parallel, and the groove portion is formed in the center portion in the width direction of the groove portion. The ridge portion may be provided to enter the groove portion, and the finishing material may be positioned by bringing the tip end portion of the ridge portion and the lower end portion of the groove portion into contact with each other. According to this structure, when the rib portion and the groove portion are fitted to each other, the protrusion portion in the width-direction central portion of the groove portion enters the recess portion in the width-direction central portion of the rib portion, and the recess portion and the protrusion portion. By confirming the positional relationship 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 position where the finishing material is attached. Moreover, since the adhesive filled between the rib portion and the groove portion does not enter between the groove portion and the protrusion portion, stable confirmation can be performed.

Further, the protrusions and the recesses may be set to a height such that a gap is formed between the rib and the groove in a state of being in contact with each other. According to this structure, when the finishing material is attached to the panel material, the excess amount of the adhesive filled in these gaps flows into the gap between the rib portion and the groove portion, so that the finishing material can be easily attached. It can be carried out.

Further, the panel material may have a rib portion on at least one surface, 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. According to this structure, it is possible to use the common panel material and the groove portion of the rectangular finishing material to cope with vertical and horizontal tension.

Further, the panel material may be an extrusion-molded cement board, and a plurality of the rib portions may be provided in parallel with the extrusion direction of the extrusion-molded cement board. According to this structure, a plurality of rib portions can be integrally formed when the extrusion-molded 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, a method for manufacturing a finishing material-attached panel according to the present invention is a method for manufacturing a finishing material-attached panel in which the attaching surface of the finishing material is attached to the attaching surface of the panel material, A plurality of inclined surfaces that are arranged in parallel on one of the pasting surfaces of one of the finishing materials so as to extend in one direction at predetermined intervals, and have cross-sections that are orthogonal to the extending direction and that have inclined surfaces that spread from the base to the end on both side surfaces. In the cross section orthogonal to the extending direction, the rib is formed in the other of the panel material or the finishing material in a direction in which the rib can be fitted at an interval that does not interfere with the rib, and the rib can be fitted in the rib. An adhesive having a hardness after curing of 75 to 90 in durometer along a groove portion having inclined surfaces on both side surfaces that narrow from a base portion toward an end portion and the inclined surface between the rib portion and the groove portion. Is applied and the finishing material is attached to the panel material, thereby bonding the finishing material to the panel material with the adhesive that is filled and cured in the space between the rib portion and the groove portion. ..

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 into the space between the inclined surfaces when the finishing material is attached and cured, and the panel material The finishing material is firmly bonded by the fitting force and the adhesive force of the cured adhesive, and the finishing material can be prevented from peeling off from the panel material.

Embodiments of the present invention will be described below with reference to the drawings. In the following embodiments, an extruded cement board (hereinafter simply referred to as “panel”) is taken as an example of the panel material 10, and a rectangular tile 30 is taken as an example of the finishing material. In addition, a configuration in which the panel material 10 includes the rib portion 11 and the tile 30 includes the groove portion 31 will be described as an example. The concept of the vertical direction and the width direction in the specification and the claims is the same as the concept of the vertical direction and the width direction when facing the panel material 10 shown in FIG.

[First Embodiment]
FIG. 1 is an end view in which a joint portion of a finishing material sticking panel 1 according to the first embodiment is partially enlarged. As shown in the figure, the panel member 10 according to the first embodiment is provided with rib portions 11 (projections) so as to extend in the extrusion direction of the surface (one surface) (one direction toward the paper surface). When the panel material 10 is an extrusion-molded cement board, it is easy to integrally form a plurality of ribs 11 in parallel when molding the extrusion-molded cement board. The material of the panel material 10 is not limited as long as the rib portion 11 can be integrally provided in addition to the extrusion-molded cement board. For example, lightweight cellular concrete, precast concrete panel, metal-based panel, etc. can be used.

The tile 30 attached to the panel material 10 is a tile 30 (FIG. 11) formed in a rectangular shape, and the back surface 32, which is an attachment surface, has a direction toward the paper surface of the tile 30 (long side direction or short side direction). ) Is provided with a groove 31. The groove portion 31 has a gap C that does not interfere with the rib portion 11 and is formed to have a widthwise dimension capable of fitting with the rib portion 11. As the tile (finishing material) 30, in addition to porcelain and porcelain tiles, natural or artificial stone materials, wood, resin, and the like, as long as the groove 31 can be formed, it is possible to use. 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 protrudes from the surface (sticking surface) 12 so as to gradually widen in a cross section (a surface shown in the drawing) orthogonal to the extending direction. In addition, the groove portion 31 of the tile 30 is formed in a trapezoidal cross section that is gradually widened from the back surface (sticking surface) 32 in a cross section (a surface shown in the drawing) orthogonal to the extending direction. Therefore, the rib portion 11 is formed on both side surfaces in the width direction of the base portion 13 (the surface 12 of the panel material 10) to extend toward the end portion 14, and the groove portion 31 has both side surfaces in the width direction of the base portion 33. Is formed on the inclined surface 35 that narrows toward the end portion 34 (the back surface 32 of the tile 30 ). In this specification and the documents of the claims, the “side surface” refers to the end surface in the width direction in the cross section orthogonal to the extending direction of the rib portion 11 as illustrated.

As a result, when 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 rib portion 11 and the inclined surface 35 of the groove portion 31 facing each other is preferably an angle of 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 the angle is smaller than 55 degrees, the tip of the rib portion 11 becomes 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 are at the same angle so as to be parallel when fitted.

The widthwise dimension of the rib portion 11 of the panel material 10 and the groove portion 31 of the tile 30 is such that 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 have As shown in the drawing, the gap C between the end 14 of the rib 11 and the end 34 of the groove 31 is 1 to the width B between the base 13 and the end 14 of the inclined surface 15 of the rib 11. It is doubled, and is also 1-2 times larger than the widthwise distance D between the base 33 and the end 34 of the inclined surface 35 of the groove 31.

If the gap C in the width direction is smaller than 1 time the gap B (distance D), the space when the tile 30 is attached (the movable range of tile position adjustment) becomes small, and the position adjustment of the tile 30 becomes difficult. On the other hand, when it is more than twice, the amount of the adhesive 50 (FIG. 2) used increases and the wedge effect due to the cured fitting decreases. In this figure, the distance D is smaller than the distance B because the end 14 of the rib portion 11 is chamfered, but the distance B may be the same as the distance 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 spaces B and D and the gap C is as follows. The adhesive 50 (FIG. 2) with which the space A is filled is set to a size that can secure a sufficient bonding strength after curing.

FIG. 2 is an end view showing a joint portion of the finishing material sticking 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 intervals B and D are set on the respective inclined surfaces 15 and 35. Therefore, the adhesive 50 is applied between the ribs 11 and the groove portions 31 by fitting the groove portions 31 of the tile 30 in a state where the adhesive agent 50 is applied (beaded) along the inclined surfaces 15 of the rib portions 11. The tile 30 can be attached to the panel material 10 by filling the space A.

The adhesive 50 is applied in an amount of 2 to 3 times 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 reduced. If it is more than 3 times, the amount of protrusion when the tile 30 is attached increases, and it takes time to remove the adhesive 50, resulting in a decrease in work efficiency.

In addition, the adhesive 50 is hard to be deformed after curing so that the adhesive 50 after curing cures in a wedge state and exerts a fitting force. Specifically, the hardness after curing of the adhesive 50 is a durometer hardness meter, as it is hard to be deformed after curing and can be cured in a wedge state after curing to maintain a bonded state to obtain a fitting force. The hardness (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 silicone/epoxy resin adhesive, an epoxy resin adhesive, or the like having a hardness after curing of 75 to 90 can be used.

After the adhesive 50 is cured, the panel material 10 and the tile 30 bonded by using the adhesive 50 are cured by filling the cured adhesive 50 between the rib portion 11 and the groove portion 31. Then, the adhesive 50 can maintain the bonded state of the panel material 10 and the tile 30. That is, due to the shape of the rib 11 of the panel member 10 provided with the inclined surface 15 and the shape of the tile 30 provided with the inclined surface 35, the adhesive 50 filled between the inclined surfaces 15 and 35. In addition to the adhesive force due to, the adhesive 50 can be cured to generate a fitting force for holding the groove portion 31 in the rib portion 11. Then, these forces can keep the tile 30 bonded to the panel material 10 with a small amount of adhesive.

Further, as in the modified example of the finishing material-attached 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 are different from each other. The back surface (sticking surface) 32 of the tile 30 may be in close contact with the front surface (sticking surface) 12 of the panel material 10 in a state of being stuck to the. 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 in 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 portion 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 Since there is no escape of the adhesive 50 to the space A, it is possible to fill the space A with the minimum necessary amount of the adhesive 50.

These may be set in an appropriate combination, but considering the filling and the protrusion of the adhesive 50, 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 be in close contact.

As described above, according to the finishing material-attached panel 1, it is possible to apply a predetermined amount of the adhesive 50 between the rib portion 11 of the panel material 10 and the groove portion 31 of the tile 30 and fit them together. It is possible to maintain a strong bond between the panel material 10 and the tile 30 for a long period of time with a smaller amount of adhesive than in the conventional case.

FIG. 4 is an end view of the finishing material attachment panel 1 in the combined 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 this finishing material pasted panel 1, the two groove portions 31 provided in the tile 30 are fitted to the two rib portions 11 provided side by side on the panel material 10, and the tile 30 is laterally attached. It is tight.

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

In addition, since the work of applying the adhesive 50 can also use a mechanical driving gun such as a caulking gun, the work efficiency is improved as compared with the case of applying it to the entire surface of the panel material 10 with a spatula or a trowel. It is also possible to reduce the loss amount of the agent 50. Furthermore, since the application area of the adhesive 50 is only the space A between the rib portion 11 and the groove portion 31, it is possible to easily adjust the position after the tile 30 is attached. Moreover, since the protrusion of the adhesive 50 due to the position adjustment of the tile 30 is less than that in the case of applying the entire surface, the surplus adhesive 50 can be suppressed, and in this respect also, the workability at the time of attachment is improved.

As described above, according to the finishing material-attached panel 1, since the groove portion 31 of the tile 30 and the rib portion 11 of the panel material 10 are bonded by using the adhesive 50 having a hardness of 75 to 90 in an appropriate amount, the tile When the tiles 30 are attached, the tiles 30 can be easily attached to adjust the position. Then, after the adhesive 50 having high hardness is cured, the panel material 10 and the tile 30 are bonded by 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 binding state with can be maintained for a long time. Moreover, this bonded state can be maintained until the adhesive 50 having high hardness undergoes cohesive failure, as described in FIG. 9, while the adhesive force is sufficiently functioning. Further, when the adhesive force of the adhesive 50 having high hardness is lowered, it can be held by the fitting force of the cured adhesive 50.

Anything will do.

In the cross section (the surface shown in the drawing) orthogonal to the extending direction, the rib portion 21 of the panel material 20 has inclined surfaces whose both side surfaces in the width direction spread from the base portion 23 (the surface 22 of the panel material 20) side toward the end portion 24. 25 are formed. Further, the groove portion 41 of the tile 40 is formed as an inclined surface 45 in which 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 the cross section (the surface shown in the drawing) orthogonal to the extending direction. Has been done.

The angle θ of the inclined surfaces 25 and 45 with respect to the front surface 22 of the panel material 20 (the back surface 42 of the tile 40) is preferably 55 degrees to 65 degrees. Further, the gap C between the rib portion 21 and the groove portion 41, the widthwise interval B between the base portion 23 and the end portion 24 of the inclined surface 25 of the rib portion 21, the width between the base portion 43 and the end portion 44 of the inclined surface 45 of the groove portion 41. Regarding the relationship between the widthwise intervals D and D, the widthwise clearance C is preferably 1 to 2 times the widthwise intervals B and D. This point is the same as in the first embodiment described above, and thus detailed description thereof is omitted.

Therefore, when fitting the groove portion 41 of the tile 40 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 so as to face each other.

Further, in this embodiment, the ridge portion 46 provided in the center portion of the groove 41 in the width direction contacts the positioning protrusion 27 of the recess portion 26 provided in the center portion of the rib portion 21 in the width direction. Has become. Since the positioning protrusion 27 is formed to have a smaller widthwise dimension than the protrusion 46, the positional relationship of the protrusion 46 with respect to the positioning protrusion 27 in the state where the protrusion 46 abuts on the positioning protrusion 27. It is possible to confirm the positional deviation of the tile 40 by viewing from the direction in which the rib portion 21 extends.

Moreover, since the adhesive 50 does not enter the positioning projection 27 and the protruding portion 46, the state in which the protruding portion 46 abuts the positioning projection 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 attached while easily adjusting its position.

FIG. 6 is an end view showing a joint portion of the finishing material sticking 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 intervals B and D are set on the respective inclined surfaces 25 and 45. Therefore, by fitting the groove 50 of the tile 40 in a state where the adhesive 50 is applied (beaded) along the inclined surface 25 of the rib 21, the adhesive 50 is applied between the rib 21 and the groove 41. The tile 40 can be attached to the panel material 20 by filling the space A.

Moreover, in this embodiment, since the adhesive holding portion 29 is provided on the base portion 23 of the rib portion 21, the surplus amount of the adhesive agent 50 applied along the rib portion 21 and filled in the space A is bonded by this adhesive. The agent holder 29 is also filled. As a result, in addition to the adhesive 50 filled in the space A between the panel material 20 and the tile 40, the adhesive 50 filled in a wide range including the adhesive holding portion 29 is hardened in a wedge shape, and then the tile 40 can be firmly held.

In addition, by contacting the protrusion 46 with the positioning protrusion 27 of the recess 26 provided between the ribs 21, the protrusion 46 does not depend on the adhesive 50 protruding from the periphery of the tile 40. It is possible to easily adjust the position of the tile 40 by confirming the positional relationship between the and the positioning protrusions 27.

That is, when the adhesive 50 protrudes from both ends of the tile 40, the end surface of the tile 40 is soiled with the adhesive 50, and it is difficult to grasp the attachment state of the tile 40 to the panel material 20. However, since the adhesive 50 that has protruded does not enter between the ridges 26 between the ribs 21 of the panel material 20 and the ridges 46 in the central portion of the tile 40, the ridges 26 and the ridges. By checking the positional relationship with 46 and the close contact state, it can be confirmed that the tile 40 is attached at an appropriate position on the panel material 20, and the position of the tile 40 can be easily adjusted. Moreover, the position adjustment of the tile 40 is facilitated and the workability is improved.

Further, as in the modified example of the finishing material-attached 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 are different from each other. The groove portion 41 of the tile 40 may be in close contact with the top portion of the rib portion 21 of the panel material 20 in the state of being attached to. In this figure, the 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 in which the rib portion 21 is in close contact. 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 portion 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 ), Since there is no escape of the adhesive 50 to the space A, it is possible to fill the space A with the minimum necessary amount of the adhesive 50.

These may be set in an appropriate combination, but in consideration of 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 tops of the ribs 21 of the panel material 20 and the groove portions 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 be in close contact.

As described above, also by the above-mentioned finishing material pasting panel 2, the tension holding force of the tile 40 can be firmly coupled by the two elements of the adhesive force of the adhesive 50 and the fitting force cured in the 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 member 20 by the fitting force of the adhesive 50 cured in the wedge state.

FIG. 8 is an end view of the finishing material attachment panel 2 in the combined state shown in FIG. As shown in the figure, the panel member 20 is provided with a plurality of rib portions 21 in parallel at a predetermined interval so as to extend in the extrusion direction of the surface. Then, in this finishing material-attached panel 2, the four (two pairs) groove portions 41 provided in the tile 40 are fitted and attached to the four (two pairs) rib portions 21 arranged in parallel on the panel material 20. The tiles 40 are horizontal. When the tile 40 is attached to the panel material 20, the adhesive 50 is applied to the inclined surface 25 of the rib portion 21 of the panel material 20 in a bead shape, 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 41, and the surplus portion is also filled in the adhesive holding portion 29. When the adhesive 50 is completely cured in the space A, the adhesive 50 is cured in a wedge state from the space A to the adhesive holding portion 29, and the tile 40 is integrated with the panel material 20. Can be tightly bound.

In addition, since the work of applying the adhesive 50 can also use a mechanical driving gun such as a caulking gun, the work efficiency is improved as compared with the case of applying it to the entire surface of the panel material 20 with a spatula or a trowel. It is also possible to reduce the loss amount of the agent 50. Further, the application area of the adhesive 50 is the space A between the rib portion 21 and the groove portion 41 and the adhesive holding portion 29, and furthermore, the positioning protrusion 27 of the panel material 20 into which the adhesive 50 does not enter. Since the tile 40 can be attached while confirming the positional relationship between the tile 40 and the protruding portion 46 of the tile 40, it is possible to easily adjust the position of the tile 40 during and after the attachment. Moreover, since the protrusion of the adhesive 50 due to the position adjustment of the tile 40 is less than that of the entire surface application, the surplus adhesive 50 can be suppressed, and in this respect also, the workability at the time of attachment is improved.

As described above, according to the finishing material-attached panel 2, the groove portion 41 of the tile 40 and the rib portion 21 of the panel material 20 are bonded together by using the adhesive 50 having a hardness of 75 to 90 in an appropriate amount. When the 40 is attached, the tile 40 can be easily adjusted in position. After the adhesive 50 having high hardness is cured, the panel material 20 and the tile 40 are bonded by 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. The binding state with can be firmly maintained for a long period of time. Moreover, this bonded state can be maintained until the adhesive 50 having high hardness undergoes cohesive failure, as described in FIG. 9, while the adhesive force is sufficiently functioning. Further, even when the adhesive force of the adhesive 50 having high hardness is lowered, it can be held by the fitting force of the cured adhesive 50.

[Example of tile stripping]
FIG. 9 is a view showing a case where the tile 40 is peeled off in the finishing material sticking panel 2 in the second embodiment shown in FIG. According to the finishing material-attached panel 2 described above, even if the adhesive force at the interface between the panel material 20 and the tile 40 is lost, the adhesive 50 that is present in a state of being hardened and filled in the space A is its own. The volume does not change. Therefore, even if the adhesive force 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 strength equal to or higher than the weight and wind pressure of the tile 40, and the tile 40 is held. be able to. Therefore, as shown in the figure, the tile 40 adhered to the panel material 20 is until the adhesive 50 cohesively breaks while the adhesive force is sufficiently functioning, or when the adhesive force of the adhesive 50 is reduced. However, it is possible to maintain the pasted state for a long time by the fitting force of the cured adhesive 50.

Let me paste it. As described above, according to the finishing material sticking panel 2, the adhesive 50 may be applied to the inclined surface 25 of the rib portion 21 in a bead shape, 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.

Although it is filled in the portion of the space A between them, it does not enter the portion between the recessed portion 26 and the protruding portion 46 in the central portion. Therefore, by visually confirming from the extending direction of the rib portion 21 how the protruding portion 46 of the tile 40 is in contact with the positioning protrusion 27 provided in the recessed portion 26 of the panel material 20, the tile 40 The finishing material sticking panel 2 can be manufactured by easily adjusting the sticking position.
