Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method and structure for attaching a cosmetic material to a building frame surface, and a decorative material. The building frame surface such as a wall surface, a floor surface, or a ceiling surface has a baseboard, a ceiling edge, a long press, etc. It can be used when attaching various cosmetic materials.
[0002]
[Background]
Conventionally, baseboards are attached to the corners where the walls and the floor face, and ceiling edges are attached to the corners where the walls and the ceiling face. Various cosmetics are attached. In addition, a long press or a window frame arranged with a pillar interposed therebetween may function as a decorative material.
[0003]
As these decorative materials, wooden materials have been used conventionally, and recently, resin products and the like have come to be used in many cases. Resin products have also been developed, and the diversification of materials is progressing. Along with this, it is possible to adopt various manufacturing techniques such as extrusion molding compared to the case of manufacturing wooden products, so a wide variety of cross-sectional shapes of decorative materials have been devised and exist. Yes. Therefore, when these decorative materials are attached to various places inside the building, various methods are employed as the attachment methods.
[0004]
For example, there is a method of attaching a decorative material directly to a building frame surface with a nail or the like, as is often seen in the attachment of a conventional wooden decorative material. On the other hand, in the case of mounting resin-made decorative materials, for which demand has been increasing in recent years, if nails are used, the nails will appear on the surface of the decorative material. Done.
[0005]
As a mounting method using such an adhesive, the base material is fixed to the building frame surface with nails, screws, etc., and the base material is covered with the decorative material by covering the base material with the adhesive. There is a method of mounting (see JP-A-9-112016, etc.). There is also a method of attaching a decorative material directly to the building frame with an adhesive. For example, like a decorative material 90 shown in FIG. 8, a leg portion 91 is formed on the back surface, and an adhesive 94 is applied to the contact surface 93 formed on the wide portion 92 at the tip of the leg portion 91 to thereby create a building frame surface. 95 (see JP-A-10-54125).
[0006]
Among these methods, the former method has a problem in that it takes time and labor for construction on the construction site, since the base receiving material is first fixed and then the decorative material is attached. Therefore, from the viewpoint of reducing the labor of such on-site construction, it is preferable to attach the decorative material directly to the building frame surface without using a base receiving material as in the latter case.
[0007]
[Problems to be solved by the invention]
However, when the method of attaching the decorative material directly to the building frame surface with the adhesive described above, the following problems arise. That is, when the contact surface to the building frame surface is formed on the back surface of the decorative material, if the contact surface is a flat surface extending over the entire back surface of the decorative material, the contact surface to which the adhesive should be applied Since the adhesive is difficult to spread because it is a smooth surface, it is difficult to apply and the problem that it is easy to peel off arises.
[0008]
Further, in the above-described decorative material 90 of FIG. 8, although the amount of material required for formation can be reduced and the adhesion and fixing can be ensured, the adhesive 94 is applied from the wide portion 92 at the tip of the leg portion 91. Since it protrudes, there is a problem that a large amount of adhesive is wasted.
[0009]
And such a problem is not only when attaching a resin-made decorative material to the building frame surface with an adhesive, but also when attaching a metal or ceramic-made decorative material to the building frame surface with an adhesive. This is a problem that occurs, and even for wooden decorative materials, the problem of difficulty in applying the adhesive and the tendency to peel off are somewhat resolved compared to other materials such as resins, but the adhesive is The problem of overhang and waste is the same.
[0010]
SUMMARY OF THE INVENTION An object of the present invention is to provide a cosmetic material mounting method, a mounting structure, and a cosmetic material that can reliably perform adhesive fixing with an adhesive and can avoid the use of useless adhesive. .
[0011]
[Means for Solving the Problems]
The present invention provides a method for attaching a decorative material to a building frame surface, wherein a concave portion is formed on the back surface of the decorative material, and the decorative material is attached to the building frame surface by filling the concave portion with an adhesive. It is a feature.
[0012]
Further, according to the present invention, in the attachment structure of the decorative material for attaching the decorative material to the building frame surface, a concave portion is formed on the back surface of the decorative material, and the decorative material is applied to the building frame surface by filling the concave portion with an adhesive. It is characterized by being attached.
[0013]
Here, the decorative material is a baseboard attached to the corner intersection of the wall surface and the floor surface, a ceiling edge attached to the corner corner intersection of the wall surface and the ceiling surface, a long press arranged across the pillar, Or a window frame or the like. The building surface is a wall surface, a floor surface, a ceiling surface or the like, and is not limited to a flat surface, but includes a curved surface and an uneven surface.
[0014]
Further, “filling” means that the adhesive is applied to the entire recess, and the adhesive 94 protrudes from the wide portion 92 at the tip of the leg portion 91 as in the above-described decorative material 90 of FIG. Thus, the purpose is to exclude the case where it is applied to a part of the recess as a result. In addition, it is preferable that the depth dimension of a recessed part shall be about 0.3-1 mm.
[0015]
Furthermore, the material for forming the decorative material is arbitrary, such as resin, metal, ceramic, wood, etc., but it is possible to easily produce a decorative material that is long and has the same cross-sectional shape by extrusion, etc., and has various cross-sectional shapes. From the standpoint of being able to form a decorative material, it is preferable to use a resin. In particular, a resin mixed with wood powder is preferable because it can give a wooden texture.
[0016]
In such this invention, when attaching a decorative material to a building skeleton surface, the recessed part formed in the back surface of a decorative material is filled with an adhesive agent. Therefore, since the recessed part is formed in the back surface of a decorative material, compared with the case where an adhesive agent is apply | coated without forming a recessed part, an adhesive agent becomes easy to spread. For this reason, application becomes easy and it becomes difficult to peel off, so that adhesion and fixing with an adhesive is ensured. Since the adhesive filled in the recesses becomes a certain amount of lump, the adhesive strength by the adhesive can be increased from this.
[0017]
Moreover, since the adhesive is fixed to the recess by filling the recess with an adhesive, it is only necessary to form a recess having a volume necessary for the adhesive fixing, and it is not necessary to form a recess having a larger volume than necessary. Therefore, it is possible to avoid the use of a wasteful adhesive such as the decorative material 90 in FIG.
[0018]
Further, examples of the decorative material used in the mounting method and mounting structure of the present invention described above include the following decorative material of the present invention. That is, the present invention is characterized in that in the decorative material attached to the building frame surface, a recess for filling the adhesive on the back surface is formed.
[0019]
In the present invention, the concave portion is one or a plurality of grooves formed along the longitudinal direction of the decorative material, one or a plurality of grooves formed along the direction orthogonal to the longitudinal direction of the decorative material, and a combination thereof. It may be a grid-like groove portion or the like, or is not limited to the groove portion, and may be a simple hole or the like, and the back surface may be a concave portion formed in a corrugated or saw-shaped cross section. It is preferable to use a simple structure.
[0020]
That is, in the decorative material described above, it is preferable that the recess includes a plurality of groove portions formed substantially parallel to each other at least along the longitudinal direction of the decorative material. Here, “substantially parallel” means not only perfect parallelism but also a state close to that. Further, “including at least a plurality of groove portions” means that a simple hole or the like may be formed in addition to the plurality of groove portions. In the case of such a configuration having a plurality of groove portions, the adhesive easily spreads along the groove portions, so that it is possible to further ensure the adhesion and fixing with the adhesive.
[0021]
Furthermore, in the decorative material described above, it is desirable that a protruding portion that protrudes toward the building frame surface side at least from the vicinity of the edge is formed on the edge of the back surface. When such a protruding portion is formed, the adhesive does not protrude from the edge of the back surface of the decorative material to the outside of the decorative material, so that useless adhesive can be avoided more reliably. It becomes like this.
[0022]
And it is desirable to set it as the structure which has a hollow part in the cosmetics mentioned above. In the case of such a structure having a hollow portion, the weight of the decorative material is reduced, so that the adhesion effect is improved and the amount of material required for forming the decorative material is reduced. Therefore, the material cost can be reduced. In forming the hollow part, extrusion molding is preferable from the viewpoint of the fact that the decorative material is long and has the same cross-sectional shape in each part and the manufacturing cost, but it is formed by blow molding or the like. May be.
[0023]
In addition, the cross-sectional shape of the concave portion of the decorative material of the present invention is arbitrary such as U shape, V shape, letter shape, vertically long rectangle, horizontally long rectangle, square, etc. In particular, the following shape may be adopted. preferable. That is, in the decorative material described above, the recess preferably has an ant-shaped cross-sectional shape. Here, the term “ant-shaped” refers to a trapezoid tenon where the original direction (the position of the abutting surface abutting against the building body surface) is narrower and the earlier side (the inner side than the position of the abutting surface) is wide. It is. In the case of a recess having such an ant-shaped cross-sectional shape, the bonding strength between the adhesive and the decorative material after solidification is increased, and it is difficult to remove each other, so that the decorative material is more securely attached. It becomes.
[0024]
Furthermore, in the above-described decorative material, a recess portion that is recessed inward from the position of the contact surface that is in contact with the building housing surface is formed on the back surface along the decorative material longitudinal direction. At least one plywood formed by overlapping a plurality of plate materials is inserted and installed along the longitudinal direction of the decorative material, and a part of the contact surface is disposed on the outermost side of the plywood and is in a direction intersecting the longitudinal direction of the decorative material It is good also as a structure formed by the remaining part of the occupied part by the plywood among the recessed parts formed by the plywood surface material which has a direction, and being filled with an adhesive agent.
[0025]
Here, “direction intersecting with the longitudinal direction of the decorative material” mainly means a direction orthogonal or substantially orthogonal to the longitudinal direction of the decorative material, but is not limited to this, and other than a right angle with the longitudinal direction of the decorative material. The direction forming an angle is also included. Note that the “abutment surface that abuts against the building frame surface” does not necessarily mean that the surface is in direct contact with the building frame surface, and adhesive enters the gap between the building frame surface and the building frame surface. In the case of contact through an adhesive.
[0026]
In the case of using such a plywood, the fiber direction of the plywood surface material that forms part of the contact surface (the direction of the grain lines) is formed in a direction that intersects the decorative material longitudinal direction. Therefore, the fiber length of the plywood surface material is shorter than when the fiber direction of the plywood surface material is formed in the decorative material longitudinal direction, so that the plywood surface material is easily peeled off partially. For this reason, fine irregularities are formed on the plywood, and grooves are also formed on the plywood, thereby improving the adhesive strength.
[0027]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0028]
[First embodiment]
FIG. 1 shows a longitudinal sectional view of a state in which a baseboard 10 which is a decorative material according to the first embodiment of the present invention is attached to a wall surface 1 which is a building frame surface. FIG. 2 is a perspective view of the baseboard 10.
[0029]
In FIG. 1 and FIG. 2, a baseboard 10 is a decorative material arranged along a corner crossing portion between a wall surface 1 and a floor surface 2 which are building frames, and is a long length extending in a direction orthogonal to the plane of FIG. And each part has the same cross-sectional shape. The skirting board 10 is an extrusion-molded product made of a resin mixed with wood powder, thereby giving a wooden texture and harmony in interior decoration.
[0030]
Two hollow portions 11 and 12 are formed in the center portion of the baseboard 10. These hollow portions 11 and 12 are formed over the entire length of the baseboard 10 in the longitudinal direction (the direction perpendicular to the plane of FIG. 1).
[0031]
On the back surface (the right surface in FIG. 1) of the baseboard 10, a plurality (here, four) of groove portions 14 that are concave portions for filling the adhesive 13 are formed. These groove portions 14 are formed in parallel to each other along the longitudinal direction of the baseboard 10. Further, a flat contact surface 15 that is in contact with the wall surface 1 through a thinly applied adhesive 13 is formed between the groove portions 13. And the vertical width dimension S of the entrance part (extension position of the contact surface 15) of each groove part 14 is about 3 mm etc., for example, and the vertical width dimension T of each contact surface 15 is about 4 mm etc., for example. is there.
[0032]
Each groove portion 14 has an ant-shaped cross-sectional shape, and forms a trapezoidal tenon called an ant groove. Accordingly, the vertical width dimension W of the groove bottom portion is larger than the vertical width dimension S of the inlet portion. In addition, it is preferable that the depth dimension D of each groove part 14 shall be about 0.3-1 mm.
[0033]
Tapered surfaces 16 are respectively formed in the vicinity of the upper and lower edges of the back surface of the baseboard 10. These tapered surfaces 16 are provided with a gentle slope descending from the outside toward the inside. Therefore, the upper and lower end edges of the back surface of the baseboard 10 are projecting portions 17 that project closer to the wall surface 1 side than the vicinity (inner side portion) of these end edges. Note that the adhesive 13 is also applied to the tapered surface 16 except for the protrusions 17.
[0034]
In such 1st embodiment, the baseboard 10 is attached to the wall surface 1 as follows.
[0035]
First, the adhesive 13 is applied to the back surface of the baseboard 10 (excluding the protruding portion 17), that is, the portions excluding the vicinity of the protruding portion 17 among the groove portions 14, the contact surface 15, and the tapered surface 16. At this time, each groove portion 14 is filled with an adhesive 13. Next, the baseboard 10 with the adhesive 13 applied to the back surface is placed at the corner crossing between the wall surface 1 and the floor surface 2, and after waiting for the adhesive 13 to dry, the baseboard 10 is attached. Complete. In addition, you may make it use a double-sided tape together in the case of attachment.
[0036]
According to such 1st embodiment, there exist the following effects. That is, since the plurality of groove portions 14 are formed on the back surface of the baseboard 10, the adhesive 13 is easily spread compared to the case where there is no such groove portion 14. For this reason, it is possible to easily apply the adhesive 13, and it is difficult to peel off, so that the adhesive fixing with the adhesive 13 can be reliably performed. And since the adhesive agent 13 with which each groove part 14 was filled becomes a certain amount of lump, the adhesive strength by the adhesive agent 13 can also be increased from this.
[0037]
Further, since the base plate 10 is bonded and fixed by filling each groove portion 14 with the adhesive 13, the groove portion 14 having a volume necessary for the bonding and fixing may be formed, and a groove portion having a larger volume than necessary may be formed. Therefore, it is possible to avoid the use of a useless adhesive such as the decorative material 90 of FIG. 8 described above.
[0038]
Furthermore, since the protrusions 17 are formed on the upper and lower edges of the back surface of the baseboard 10, when the baseboard 10 is attached to the wall surface 1, the adhesive 13 applied to the back surface of the baseboard 10 is Protruding from the upper and lower edges of the tree 10 to the outside (upper or lower) of the baseboard 10 can be prevented. For this reason, use of a useless adhesive agent can be avoided much more reliably.
[0039]
And since the baseboard 10 has the hollow parts 11 and 12, weight reduction of the baseboard 10 can be achieved. For this reason, while being able to aim at the improvement of an adhesion effect, since the quantity of the material required for formation of the baseboard 10 can be reduced, reduction of material cost can also be aimed at.
[0040]
Moreover, since each groove part 14 has an ant-shaped cross-sectional shape, since the joint strength of the adhesive 13 and the baseboard 10 after solidification becomes large and it becomes difficult to remove each other, the baseboard 10 is attached. It can be made even more reliable.
[0041]
[Second Embodiment]
The perspective view of the baseboard 20 which is the decorative material of 2nd embodiment of this invention is shown by FIG. The baseboard 20 is arranged along the corner intersection of the wall surface 1 and the floor surface 2, which are the building frame surfaces, and is attached to the wall surface 1 by the adhesive 13, similarly to the baseboard 10 of the first embodiment. It is a cosmetic material.
[0042]
In FIG. 3, the baseboard 20 is configured to include a main body 21 that is an extrusion-molded product made of a resin mixed with wood powder in order to give a wood texture, and a plywood 30 that is formed by superposing a plurality of plate materials. ing.
[0043]
Since the main body 21 is an extrusion-molded product, each part has the same cross-sectional shape in the longitudinal direction (X direction in the figure). A plurality of (here, five) recesses 22 are formed on the back surface of the main body 21. The hollow portions 22 are formed in parallel to each other along the longitudinal direction of the main body 21.
[0044]
In each of these recesses 22, one plywood 30 is inserted and installed along the longitudinal direction of the main body 21, that is, along the formation direction of each recess 22. Each of these plural (here, five) plywoods 30 and the main body 21 are fixed by an adhesive or the like. In addition, the lower end surface of each plywood 30 is brought into contact with the upward side surface of each recessed portion 22, thereby positioning each plywood 30.
[0045]
The vertical width dimension M of each plywood 30 is smaller than the vertical width dimension L of each recess 22, and therefore the area of each plywood 30 is smaller than the area of each recess 22. And the groove part 23 which is a recessed part for filling the adhesive agent 13 by the remaining part (part of the up-and-down width dimension N) of the occupied part by the plywood 30 among each hollow part 22 is formed.
[0046]
Moreover, the some board | plate material which comprises each plywood 30 is piled up one by one in the state in which the fiber directions are mutually substantially orthogonal. And the fiber direction of the plywood surface material 31 disposed on the outermost side of each plywood 30 is a direction (Y direction in the figure) substantially orthogonal to the longitudinal direction (X direction in the figure) of the baseboard 20. For this reason, since the length of the fiber is short, the plywood surface material 31 is partially peeled, and fine irregularities are formed on the surface 32 of each plywood 30.
[0047]
The thickness of each plywood 30 matches the depth dimension K of each recess 22. Accordingly, the flat surface 24 formed between the recesses 22 on the back surface of the main body 21 and the portion of the surface 32 of each plywood 30 where the plywood surface material 31 is not peeled off are contacted to the wall surface 1. A contact surface 25 is formed.
[0048]
Tapered surfaces 26 are formed in the vicinity of the upper and lower edges of the back surface of the baseboard 20 in the same manner as the tapered surface 16 of the baseboard 10 of the first embodiment. These tapered surfaces 26 are provided with a gentle slope descending from the outside toward the inside. Therefore, the upper and lower end edges of the back surface of the baseboard 20 are projecting portions 27 that project closer to the wall surface 1 side than the vicinity (inner side portion) of these end edges. Note that the adhesive 13 is also applied to the tapered surface 26 except for the protrusion 27.
[0049]
In such a second embodiment, the baseboard 20 is attached to the wall surface 1 as follows.
[0050]
First, in a factory, each plywood 30 and the main body 21 are previously fixed and integrated with an adhesive or the like. Next, it adheres to the back surface of the baseboard 20 (excluding the protruding portion 27), that is, each groove portion 23, the flat surface 24, the surface 32 of each plywood 30, and the portion of the tapered surface 26 excluding the vicinity of the protruding portion 27. Agent 13 is applied. At this time, each groove portion 23 is filled with the adhesive 13. Further, the plywood surface material 31 is partially peeled off, so that the adhesive 13 is also filled into the concave portions having fine irregularities formed on the surface 32 of each plywood 30.
[0051]
After that, the baseboard 20 with the adhesive 13 applied on the back surface is placed at the corner crossing between the wall surface 1 and the floor surface 2, and the attachment of the baseboard 20 is completed after the adhesive 13 is dried. To do. In addition, you may make it use a double-sided tape together in the case of attachment.
[0052]
According to such a second embodiment, as in the first embodiment, the application of the adhesive 13 by the formation of the plurality of grooves 23 on the back surface of the baseboard 20 is facilitated, and the adhesive fixing by the adhesive 13 is performed. It is possible to obtain the effects of ensuring, improving the adhesive strength based on the lump action by filling each groove 23 with the adhesive 13, avoiding useless use of the adhesive, and preventing the protruding portion 27 from protruding the adhesive 13. .
[0053]
Further, compared to the case of the first embodiment, although it takes time to fix each plywood 30 and the main body 21, the fiber direction of the plywood surface material 31 is substantially perpendicular to the longitudinal direction of the baseboard 20 (in the drawing). Since the length of the fiber is short, the plywood surface material 31 is partially peeled off, whereby fine irregularities can be formed on the surface 32 of each plywood 30. For this reason, compared with said 1st embodiment, adhesive strength can be improved further.
[0054]
Note that the present invention is not limited to the above-described embodiments, and modifications and the like within a range in which the object of the present invention can be achieved are included in the present invention.
[0055]
That is, although the base plate 10 of the first embodiment has two hollow portions 11 and 12, the number of hollow portions provided in the decorative material of the present invention is not limited to two. It may be one or three or more, and the size is arbitrary as long as it is within the range in which the strength of the member can be maintained. Further, the installation of the hollow portions 11 and 12 may be omitted. However, it is desirable to provide the hollow portions 11 and 12 in that the adhesive strength can be improved by reducing the weight. In addition, you may provide a hollow part in the baseboard 20 of said 2nd embodiment.
[0056]
Further, the base plates 10 and 20 of the above-described embodiments are formed with the groove portions 14 and 23 which are relatively large recesses. However, as in the base plate 40 of FIG. May be.
[0057]
Furthermore, although the protrusions 17 and 27 were formed by the taper surfaces 16 and 26 in the baseboards 10 and 20 of each said embodiment, like the baseboard 50 of FIG. The protruding portion 51 may be formed on the edge of the back surface of the baseboard 50. In short, if the protruding portion 51 is protruded closer to the wall surface 1 than the vicinity, the effect of preventing the applied adhesive 13 from protruding can be obtained.
[0058]
In the baseboard 20 of the second embodiment, one plywood 30 is inserted and installed in one recess 22, but in one recess 61 as in the baseboard 60 of FIG. 6. In addition, a plurality of plywoods 62 may be inserted and installed. Moreover, in forming the groove part 63 which is a recessed part for filling the adhesive 13 by inserting and installing the plywood 62 in the recessed part 61, the end face of the plywood 62 is not necessarily formed in the recessed part as shown in FIG. It is not necessary to contact the side surface 64 of 61. However, if it is made to contact | abut to the side surface 64, the positioning at the time of fixation of the plywood 62 can be performed, and the effort of manufacture of a decorative material can be reduced.
[0059]
In addition, unlike the baseboard 70 in FIG. 7, the recess 72 for inserting and installing the plywood 71 does not have to be completely concave, and in short, is formed inwardly from the position of the contact surface 73. The plywood 71 may be inserted and installed.
[0060]
【The invention's effect】
As described above, according to the present invention, the concave portion is formed on the back surface of the decorative material, and the concave portion is filled with the adhesive and the decorative material is attached to the building frame surface. And the use of useless adhesive can be avoided.
