Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention facilitates the construction of a sheet-shaped pattern finishing material when the sheet-shaped pattern finishing material is adhered to the inner and outer surfaces of the building such as wall surfaces, pillar surfaces, ceilings, floors, etc. Further, the present invention relates to an improved joint pattern forming member capable of easily forming a colored joint pattern.

[0002]

[Prior Art]

 In recent years, for example, the outer wall surface of concrete in buildings and the like has been generally subjected to various spray finishes with a spray material to enhance waterproofness and to give a beautiful appearance. It is seamless and tends to have a monotonous finish.

[0003] Although there are those that have irregularities such as scatter finish and pattern roller finish, there are limits to the appearance of patterns, and for example, joint patterns such as bricks and tiles, and heavy patterns. It is difficult to finish it in a feeling pattern.

On the other hand, a finishing method for improving aesthetics by pasting thin bricks or tiles on the wall surface has been more widely used than before, but in this case, joints, which are gaps between the bricks and tiles, are also treated. It is important because it has a great impact on aesthetics.Because it requires bonding and jointing of each piece such as bricks and tiles, it is low in efficiency and costly, and when it becomes old, weathering, thermal expansion, etc. These bricks and tiles may come off and fall off, which may be dangerous in high-rise buildings.

Therefore, in recent years, a sheet-like finishing material made of a plastic sheet-like article which has almost the same appearance as those of bricks, tiles, etc., but has a considerably low specific gravity and also has some flexibility. A construction method is being used in which it is bonded to the wall surface of a building to give a joint pattern and solid feeling similar to the tile and brick finish.

The sheet-like finishing material made of such a plastic sheet-like material has almost the same appearance as bricks and tiles as described above, but since it has a much smaller specific gravity, it is not heavy and peels off due to its weight. It is less likely to drop and fall, and even if it does fall, its relative gravity is smaller and its rigidity is smaller, so it is relatively less dangerous and its price is relatively cheap. In recent years, it has been often applied to buildings and the like.

[0007]

[Problems to be solved by the device]

 However, as with conventional bricks and tiles, it is necessary to bond sheet-like pattern finishing materials made of such plastic sheet-like materials one by one, with appropriate joint intervals. This requires a so-called joint treatment for coloring the joint color later, which is very troublesome.

That is, such finishing materials are generally finished with straight and parallel spacings. In the case of such joint patterns, even one of them cannot be bonded in parallel. When it exists, it tends to be very conspicuous, ruining the overall aesthetics, and requires considerable skill.

Further, even if the joints are successfully pasted, the next time the joints are processed, the joints cannot be colored neatly along the parallel lines to a predetermined width, and the joints may stick out or stick out. If the size is small, the joint pattern will become dirty, and the appearance will be greatly deteriorated even if the bricks and tiles are beautifully used. It is an object of the present invention to provide an improved joint pattern forming member that makes it extremely easy to apply a sheet-like pattern finishing material and can easily and easily form a beautifully colored joint pattern. To do.

[0010]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the joint pattern forming member of the present invention is colored with a desired joint color and is wider than the desired joint width and has an adhesive layer formed on the back surface thereof. The strip-shaped film, which is narrower than the core member and the joint core member and has the same width as the target joint width, and the strip-shaped film having an adhesive layer on the back side thereof is A joint pattern forming member, which is peelably adhered and laminated along a longitudinal direction of the joint core member on a substantially central portion in the width direction of the joint core member.

In the above structure, it is preferable that the joint core member is a joint core member made of a synthetic resin foam sheet. Further, in the above structure, it is preferable that the joint core member is a joint core member made of a synthetic resin sheet or a film.

Further, in the above structure, it is preferable that the thickness of the strip-shaped film-shaped material is 200 μm or less. Further, in the above structure, the thickness of the joint core member is preferably 1500 μm or less.

Further, in the above structure, it is preferable that the joint core member is a joint core member in which holes are formed in both side portions where the strip-shaped film-shaped material is not laminated.

[0014]

[Action]

 The joint pattern forming member of the present invention is a joint core member colored with a desired joint color and wider than the desired joint width and having an adhesive layer on the back side thereof, and the joint core. A strip-shaped film that is narrower than the member and has the same width as the desired joint width, and a strip-shaped film with an adhesive layer on the back side is almost the same in the width direction of the joint core member. Since the adhesive core is peelably attached along the longitudinal direction of the joint core member on the vicinity of the central part, this joint pattern forming member forms a joint pattern such as a building wall surface to be constructed in advance. The adhesive is applied to the entire surface, and then the adhesive is applied to the entire surface from above, along the edge of the strip-shaped film-like material having the same width as the joint width narrower than the joint core member of the joint pattern forming member. Since it is possible to attach a sheet pattern finish material, The position of the sheet-like finishing material can be accurately and accurately attached, and after this attachment, the strip-shaped film-like material formed with the same width as the joint width can be peeled off and removed easily. An improved joint pattern forming member capable of forming a colored joint portion and easily and neatly forming a joint pattern using a sheet-like pattern finishing material without requiring any skill. Can be provided.

In the above-mentioned configuration, when the joint core member is a joint core member made of a synthetic resin foam sheet, the foam sheet has elasticity, so that the sheet-shaped pattern finishing material is not likely to undergo thermal expansion or expansion. Even if shrinkage occurs, there is some conformity and there is no gap between the pattern finish and the joint.

Further, in the above-mentioned configuration, the joint core member is preferably a joint core member made of a synthetic resin sheet or a film, whereby joints that are easily available and have higher mechanical strength can be formed, which is preferable. ..

Further, in the above-mentioned constitution, by adopting a preferable mode in which the thickness of the strip-shaped film-like material is 200 μm or less, when the adhesive is applied to the entire surface from above, the adhesive is relatively uniform over the entire surface. When the strip-shaped film is peeled off after being applied and thus the adhesive has been dried, the adhesive is sharply cut along both sides of the joint, thereby maintaining a good appearance of the joint. It is possible to prevent such a phenomenon that the aesthetics of the joint is significantly deteriorated.

Further, in the above-mentioned structure, the thickness of the joint core member is set to 1500 μm or less, so that even if a part of the end portion of the sheet-like pattern finishing material is overlapped and stuck on this, the step Since it is not so large, it is possible to firmly and easily attach it, and it is possible to make the deterioration of the appearance due to the step not to be a problem at all.

Further, in the above-mentioned configuration, the joint core member is a joint core member in which holes are formed in both side portions where the strip-shaped film-like material is not laminated, and the joint core member is made to pass through the holes of the joint core member. The adhesive enables the sheet-like pattern finishing material to be directly and firmly adhered to the construction target surface (for example, the wall surface of the building), and thus the joint core member that serves as a joint is more firmly fixed to the intended construction wall surface. can do.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view of an example of a joint pattern forming member of the present invention.

The joint pattern forming member 1 has a joint core member 2 which is wider than a desired joint width colored in a desired joint color and has an adhesive layer 3 formed on the back side thereof. The band-shaped film 4 is narrower than the joint core member 2 and has the same width as the target joint width, and the band-shaped film 4 having the pressure-sensitive adhesive layer 5 on the back side thereof is the pressure-sensitive adhesive. A structure in which the joint core member 2 is releasably adhesively laminated along the longitudinal direction of the joint core member 2 on the vicinity of a substantially central portion in the width direction of the joint core member 2 via a layer 5. Of course, if necessary, the pressure-sensitive adhesive layer 3 may be releasably covered with a release paper (not shown) or the like.

As the joint core member, it is preferable to use a relatively thin member having good strength, weather resistance, durability and the like. For example, a polyolefin-based material such as a polyethylene foam or a polyethylene-propylene co-polymer foam is used. The foam has suitable elasticity and strength and is preferably used.

When these foams are used, since they have elasticity, they have some followability even if thermal expansion or contraction of the sheet-shaped pattern finishing material occurs, and a gap is generated between the pattern finishing material and the joint. There is no such thing.

The joint core member does not necessarily have to be a foam, and may be a joint core member made of a synthetic resin sheet or film. In this case, the sheet or film is typically polyethylene, polypropylene or the like. Polyolefins represented by polyolefins, polyethylene terephthalate, polyethylene-2,6-naphthalate, polyvinyl chloride, polyphenylene sulfide (PPS), various natural rubbers, synthetic rubbers and the like are also preferably used. They can have higher mechanical strength than foams and are preferably used when it is desired to form stronger joints.

The thickness of these joint core members is preferably 1500 μm or less, and is preferably 50 μm or more from the viewpoint of strength. Particularly when a foam is used, it is more preferably 500 μm or more. That is, if the thickness of the joint core member is too thick, a step may be formed in the sheet-like pattern finishing material formed by being stuck on the joint core member, which may make it difficult to adhere or the step may deteriorate the appearance.

As the color of these joint core members, those which are colored in the desired joint color are used. The method for coloring the joint core member is arbitrary, but a joint core member of any desired color can be easily obtained, for example, by adding a pigment or the like during the production thereof.

Next, a strip-shaped film having a width narrower than that of the joint core member and having the same width as the target joint width, and the adhesive film 5 is provided on the back side thereof. As the strip-shaped film constituting 4, a polyester film, a polypropylene film or the like is preferably used because it has sufficient strength and is inexpensive and easily available, but is not particularly limited to these two. Of course, other films may be used as long as they meet the purpose of the present invention.

From the viewpoint of strength, it is preferable to use these biaxially stretched films. The thickness of the strip-shaped film 4 is preferably 200 μm or less, so that when the adhesive is applied to the entire surface from above, the adhesive is applied uniformly over the entire surface, and therefore the strip-shaped film 4 is formed. Even when the object is peeled and removed, it is possible to prevent a phenomenon in which the excess adhesive is solidified by sticking on the joint and significantly lowering the aesthetics of the joint. That is, when the thickness of the strip-shaped film 4 is too large, when the adhesive is applied to the entire surface from above, a large step is formed at the boundary portion between the joint core member 2 and the strip-shaped film 4, so that a comparison is made. When an adhesive with a low dynamic viscosity is applied to the entire surface, an adhesive pool is created at this boundary portion, and when the strip-shaped film-like material 4 is removed later, the adhesive that has accumulated here will be the joint. The core film 2 sticks out to a portion where the strip-shaped film-like material 4 is removed (that is, a portion which becomes a joint) and solidifies on the portion, so that the joint is stained and the appearance is deteriorated.

On the other hand, when an adhesive having a relatively high viscosity is used, on the contrary, the adhesive may not reach the vicinity of the boundary if a large step is formed at the boundary. Further, although not particularly limited, those having a range of about 50 μm or more are preferably used in terms of strength.

FIG. 2 is a perspective view showing an example of another aspect of the joint pattern forming member of the present invention. The joint pattern forming member 7 is the same as the joint core member 2 shown in FIG. 1 except that the joint core member 2 has holes 8 formed on both side portions where the strip-shaped film-like objects 4 are not laminated. Is one.

Since the joint pattern forming member 8 has the holes 8 formed in the joint core member 2, the sheet-shaped pattern finishing material and the construction target are bonded with the adhesive through the holes 8 of the joint core member 2. This is one of the preferred modes since it can be directly and firmly adhered to the surface (for example, the wall surface of the building), and thus the joint core member serving as the joint can be more firmly fixed to the target construction wall surface. is there.

Next, using the joint pattern forming member 1 of the present invention, a sheet-like pattern finishing material is attached to a wall surface of a target building or the like. As the sheet-like pattern finishing material used at this time, It is possible to use a known sheet-like interior / exterior finishing material for construction (so-called plastic brick or plastic tile) of this type.

The most commonly used one is, for example, a woven, knitted or plastic sheet made of a skin-based spraying material containing an acrylic resin emulsion as a main component or a mixture of a large amount of brick, ceramics or natural stone powder. It is used by spraying it on a base sheet such as a sheet, drying and solidifying it, and cutting it into a desired tile or brick size.

FIG. 3 shows a perspective view of an example of these sheet-shaped pattern finishing materials 10. For example, 11 is a skin-based spraying material containing acrylic resin emulsion as a main component, or a finishing material formed by drying and solidifying a large amount of bricks, ceramics, or natural stone powder mixed in, and 12 A base sheet such as a woven fabric, a knitted fabric or a plastic sheet.

The base sheet 12 is not always necessary, but when the sheet-shaped pattern finishing material 10 is adhered to the construction surface of a building with an adhesive, a base sheet having a rough surface such as a woven fabric or a knitted fabric should be used. Is preferable from the viewpoint of adhesive strength.

Next, using the joint pattern forming member 1 or 7 of the present invention as shown in FIG. 1 or 2, a sheet-like pattern finish as shown in FIG. 3 is applied to a construction surface such as a wall surface of a building. The process of adhering the material 10 with an adhesive will be described with reference to FIGS.

In the following drawings, for ease of explanation, the case where the joint pattern forming member 1 of the type shown in FIG. 1 is used will be described unless otherwise specified. Further, illustration and description of the adhesive layers 3 and 5 described in FIG. 1 are omitted.

First, the joint pattern forming member 1 of FIG. 1 is attached to the target construction surface, for example, the surface of the wall 20, via the adhesive layer 3 under the joint pattern forming member 1. FIG. 4 is a sectional view showing this state.

Next, as shown in FIG. 5, an adhesive 21 is applied to the entire surface of the wall 20 including the joint pattern forming member 1 of the present invention. The adhesive used at this time may be selected appropriately depending on the place of use, type of material, purpose, etc., but elastic adhesives such as elastic epoxy adhesives are stable for a long time. It is one of the most preferable things because it can be adhered. At this time, if the thickness of the strip-shaped film-like material 4 is too thick, a large step is formed at the boundary portion between the joint core member 2 and the strip-shaped film-like material 4, so that the adhesive having a relatively low viscosity is entirely covered. When it is applied to the adhesive film, an adhesive agent is accumulated at this boundary portion, and when the strip-shaped film material 4 is removed later, the adhesive agent that has accumulated here is removed from the strip-shaped film material of the joint core member 2. When the strip-shaped film-like material is peeled off after the adhesive has solidified because the adhesive layer has thickened, it protrudes to the part where 4 is removed (that is, the part that becomes the joint). If the adhesive layer cannot be cut sharply, the appearance of joints will deteriorate.

On the other hand, when an adhesive having a relatively high viscosity is used, on the contrary, the adhesive may not reach the vicinity of the boundary if a large step is formed at the boundary. Therefore, as the strip-shaped film 4 of the present invention, a film having a relatively small thickness such as a film is used so that such a defect does not occur.

Next, as shown in FIG. 6, the sheet-shaped pattern finishing material 10 as shown in FIG. 3 is attached along the edges of the strip-shaped film-shaped material 4 as a guide. Since the strip-shaped film-shaped material 4 can be used as a guide for this attachment, the sheet-shaped pattern finishing material 10 can be easily attached to a precise position.

Next, as shown in FIG. 7 (perspective view), the strip-shaped film-shaped material 4 is peeled and removed. Therefore, in this case, the adhesive 21 adhering to the upper surface is also removed at the same time. A cross-sectional view showing a state where the construction is completed is shown in FIG. 8 and a plan view thereof is shown in FIG. In the above drawings, the parts denoted by the same reference numerals as those in FIGS. 1 and 3 indicate the same members as those in FIGS. 1 and 3, and therefore detailed description thereof will be omitted.

As is apparent from FIGS. 8 and 9, the surface of the joint core member 2 underneath is revealed by peeling and removing the strip-shaped film-like material 4 as shown in FIG. 7, that is, the joint 22 of the desired color is formed. Will be formed.

Moreover, both end portions of the joint core member 2 serving as joints are partly inserted into and fixed to the lower side of the sheet-shaped pattern finishing material 10 to reduce the risk of peeling or falling off. Further, when the joint pattern forming member 7 according to another embodiment of the present invention as shown in FIG. 2 is used, the sheet-shaped pattern finishing material 10 is made of an adhesive because of the existence of the holes 8 described above. 8 directly and firmly adheres to the construction surface of the construction object such as a building. Therefore, the joint core member 2 serving as the joint can be more firmly fixed to the intended construction wall surface. Therefore, it is possible to further reduce the risk of peeling and dropping even after long-term use.

[0045]

[Effect of the device]

 The joint pattern forming member of the present invention allows the sheet-like pattern finishing material to be accurately attached to the position, and after the attachment, the strip-shaped film having the same width as the joint width is formed. By peeling and removing the object, it is possible to easily form a colored joint portion, and to easily and neatly form a joint pattern using a sheet-like pattern finishing material without requiring any skill. It is possible to provide a joint pattern forming member that can be formed.

In the above-mentioned configuration, the joint core member is a joint core member made of a synthetic resin foam sheet, so that even if thermal expansion or contraction of the sheet-shaped finish material occurs, the joint core member has some conformability. It is possible to provide a joint pattern forming member that does not cause a gap between the pattern finishing material and the joint.

Even when the coating is applied and therefore the strip-shaped film-like material is peeled off and removed, excess adhesive may squeeze over the joints, or the adhesive layer may not be cut sharply and the aesthetics of the joints may be significantly reduced. It is possible to provide a joint pattern forming member capable of preventing the above.

Further, in the above-mentioned structure, the thickness of the joint core member is set to 1500 μm or less, so that even if a part of the end portion of the sheet-shaped finish material is overlapped and stuck on this, the step Since it is not so large, it is possible to provide a joint pattern forming member that can be firmly and easily bonded and that the deterioration of the appearance due to the step difference does not pose any problem.

Further, in the above-mentioned structure, the joint core member is a joint core member in which holes are formed in both side portions in which the strip-shaped film-like material is not laminated, and the joint core member is passed through the holes of the joint core member. The adhesive enables the sheet-like pattern finishing material to be directly and firmly adhered to the construction target surface (for example, the wall surface of the building), and thus the joint core member that serves as a joint is more firmly fixed to the intended construction wall surface. It is possible to provide a joint pattern forming member that can be formed.
