Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is applicable to all kinds of wall surfaces (walls and floors made of concrete, mortar, PC board, slate, ALC board, etc., roads, manhole covers, etc.). TECHNICAL FIELD The present invention relates to an improved technique for a surface decorative finishing formwork used for forming decorative patterns such as pictures, characters and geometric figures having a joint pattern on the surface of a building or object).

(Prior art) Conventionally, after pasting a special form frame punching out the joint pattern part of the tile and the joint part for edging of other designs on the wall surface etc.,
A surface layer material such as a special color material or paint is laid or sprayed on the punched part, and the special form is removed after the surface layer material is hardened, so that a free joint pattern on the wall surface and a decorative pattern of a desired color tone A surface decoration finishing method for forming wall surfaces is known.

As a mold used in this method, a foamed polyethylene double-sided pressure-sensitive adhesive sheet is used as a core material, and parts other than the joint pattern are punched out from a laminated sheet in which release paper is attached to the outer surfaces of both the front and back pressure-sensitive adhesive layers of the core material. Was used.

Then, in the surface finish finishing method such as wall surface using this formwork, the release paper of the joint pattern portion attached to the front side adhesive layer of the core material is peeled off from the core material before the surface layer material is cured, It was possible to cut off the excess surface layer material protruding to the joint pattern side, and thus to finish the edge of the surface layer material cleanly.

(Problems to be solved by the invention) However, in the conventional formwork structure, there is no problem if the surface layer materials are all the same color such as a brick pattern, but with the joint pattern part as a boundary. When the color of the surface layer material is changed by the above method, the following inconvenience occurs.

That is, when the surface layer material has a plurality of colors, it is necessary to divide the surface layer material in order to prevent color mixing, and to perform the curing step and the curing step separately for each color. Although it must be done separately for each color of the surface material, the work of cutting out the curing sheet along the contour of the surface material in the same color range requires a lot of time and labor, and requires skill. This was a cause of increased cost and longer construction period.

Further, when the surface layer material has a plurality of colors as described above, the release paper of the joint pattern portion is peeled off from the core material before the surface layer material of one color is cured, and the surface layer of the other color adjacent to this is removed. There is a problem that the outline of the pattern is blurred because there is no means to finish the edges of the material cleanly.

Therefore, the present invention has been made to solve the above problems, and the purpose thereof is to eliminate the troublesome work of cutting out the curing sheet even when the design is expressed in a plurality of colors. At the same time, it is to provide a formwork for surface decoration finishing such as a wall surface, which can bring out the outline of a pattern neatly.

(Means for Solving the Problem) In the present invention, as a means for solving the above problems, a pressure-sensitive adhesive layer whose outer surface is protected by a release sheet is provided on the back surface of the core material, and a peelable release layer is provided on the surface. A formwork comprising a layer and a formwork-constituting laminate cut along the both side edges of a joint pattern portion serving as the edging of a decorative pattern so as to be extractable, the surface of the core material The side was subjected to a release treatment, an adhesive layer was provided on the back surface side of the release layer, and the release layer in the joint pattern portion was cut along with the adhesive layer on the back surface substantially along the center line.

(Function) In the frame for surface decoration finishing such as the wall surface of the present invention, as described above, the surface side of the core material is subjected to the release treatment, and the adhesive layer is provided on the back side of the release layer. The peeling layer is peeled from the core material surface of the laminated body part that has been extracted for the purpose of making the surface of the applied surface material easy and accurate by directly sticking the peeling layer using the adhesive layer provided on the back side. Therefore, it is possible to reduce the work period and the cost by eliminating the troublesome work of cutting out the curing sheet.

Further, since the peeling layer of the joint pattern portion is cut in advance along with the adhesive layer on the back surface thereof substantially along the center line thereof, the surface layer material has a plurality of colors and the surface layer material is averaged or sprayed and the curing step is performed for each color. Even if it is necessary to perform the process separately, it is possible to peel off the release layer of the joint pattern portion separately according to each step, and therefore, the joint layer is adjacent to the joint pattern portion as a boundary. Both edges of both surface materials are finished neatly and the outline of the design can be made beautiful.

(Example) Hereinafter, the Example of this invention is described in detail based on drawing. In this embodiment, the case where the surface layer material is thickly formed with a trowel is taken as an example.

First, the configuration of the embodiment will be described.

As shown in FIG. 1 and FIG. 2, a mold A for finishing a surface decoration such as a wall surface of this embodiment has a core material 1 which constitutes a main body of the mold.
As the foamed polyethylene sheet having a thickness of 3.0 mm, a pressure sensitive adhesive layer 3 whose outer surface is protected by a first release paper 2 is provided on the back surface of the core material 1, and the front surface side of the core material 1 is provided. And a second release paper 4 formed of a foamed polyethylene sheet having a thickness of 1.0 mm with a pressure-sensitive adhesive layer 5 adhered to the back surface of the core material 1 in a peelable state. It is formed on the laminated body a which is adhered.

Then, the laminate a is cut into a state in which it can be cut out along both side edges 60, 60 of the joint pattern portion 6 which is an edge of the decorative pattern, and the second release paper 4 of the joint pattern portion 6 and The pressure-sensitive adhesive layer 5 is cut along the center line m, and can be peeled off from the surface of the core material 1 separately at the cut 40.

The cutting work along the both side edges 60, 60 and the center line m can be performed manually if the decorative design is simple, but the design is complicated, and especially the width of the joint pattern part When the width is narrow, it is possible to cut easily and accurately by using a laser processing machine capable of program control of processing.

That is, in this embodiment, as shown in FIG.
A laser processing machine B that can move in the -Y, ZZ directions is used, and the cutting processing of the laminated body a set below is performed by the control device C whose movement is programmed in advance according to the design. . Incidentally, when the laminated body a is cut so as to be punchable like the both side edge portions 60, 60 of the joint pattern portion 6 and only the second release paper 4 and the pressure sensitive adhesive layer 5 are cut like the center line m. The depth adjustment when performing is performed by height control by moving the laser processing machine B in the Z-Z direction (vertical direction).

Next, a method for finishing the surface decoration of the wall surface using the above-mentioned mold A will be described with reference to FIG.

(A) Basement coating material applying step First, the basement coating 8 is applied to the entire surface of the wall surface F for curing (see FIG. 4 (a)). The basement coating material 8 constitutes a joint pattern portion in the decorative design, and for example, a brown coating material is used.

(B) Formwork construction and surface layer material application step After the basement coating material 8 is sufficiently cured, the upper surface thereof is marked out according to the construction drawing. Then, as shown in FIG. 4 (a), the first release paper 2 was peeled off from the back surface of the laminate a, and the laminate a was adhered to the surface of the basement coating material 8 along the marking line. After that, as shown in FIG. 4B, only the laminated body portion 1a of the first colored portion is extracted from the laminated body a, and the extracted portion has a first surface layer material colored red, for example.
9a is pushed in with a trowel and the surface is leveled so that the upper surface thereof coincides with the upper end surface of the laminated body a. When the first surface layer material 9a is slightly hardened, as shown in FIG. By separating and peeling the second release paper 4a along the outer peripheral edge from the cut 40 separately from the other, the extra surface layer material protruding to the joint pattern portion 6 side is cut off, and the edge of the first surface layer material 9a is cut off. It can be finished neatly. Then, the second release paper 4 having the pressure-sensitive adhesive layer 5 on the back surface is peeled from the front surface of the core material 1 of the laminated body portion 1a extracted for applying the first surface layer material 9a, and then the fourth release paper 4 is removed. As shown in the figure (d), the surface of the first surface layer material 9a is adhered to the surface of the first surface layer material 9a for masking, and is cured until the first surface layer material 9a is cured.

Next, only the laminated body portion 1b of the second color to be applied is extracted from the laminated body a, and the second surface layer material 9b colored white, for example, is pushed into the extracted portion with a trowel to obtain the first surface layer material. The surface is leveled by the same procedure as in the case of 9a, the second release paper 4b is peeled off, and the second release paper 4 is adhered and cured (see FIG. 4 (e)).

As described above, the surface layer material of all the color portions is divided into different colors for construction.

(C) Formwork removing step When the surface layer materials of all colors are cured, the core material 1 forming the formwork is peeled and removed, so that the contour is trimmed by the basement coating material 8 of the joint pattern portion 6. A pattern is formed. (See FIG. 4 (f)).

As the material for the basement coating material 8 and the surface layer materials 9a, 9b ..., depending on the type of binder used, reaction-curing type using methyl methacrylate, emulsion type using acrylic emulsion, cement and acrylic emulsion are used. A polymer cement type used in combination is used.

As described above, in the frame A for surface decoration finishing such as the wall surface of the present embodiment, as described above, the front surface side of the core material 1 is peeled off, and the back surface side of the second release paper 4 is exposed. Since the pressure-sensitive adhesive layer 5 is provided, the second release paper 4 is peeled off from the surface of the core material 1 of the surface layer materials 9a, 9b ... By directly adhering the second release paper 4 using the pressure-sensitive adhesive layer 5 provided on the back surface side, the surface of the applied surface layer material 9a, 9b ... Can be masked easily and accurately. Therefore, the troublesome work of cutting out the curing sheet becomes unnecessary, and the work period and cost can be reduced.

In addition, the second release paper 4 of the joint pattern portion 6 is cut along with the pressure-sensitive adhesive layer 5 on the back surface thereof substantially in advance along the center line m, so that the surface layer material has a plurality of colors and the surface layer material is smoothed. Or, even if it is necessary to perform the spraying and curing steps separately for each color, the second release paper 4a, 4b ... of the joint pattern portion 6 should be peeled off separately according to each step. Therefore, the edges of both surface layers 9a and 9b adjacent to each other with the joint pattern portion 6 as a boundary are both finished neatly so that the contour of the design can be taken out neatly.

As described above, in the frame A for surface decoration finishing such as the wall surface of the present embodiment, as described above, the second release paper 4 of the joint pattern portion 6 is previously cut along the center line m thereof. Then
Even when the surface layer materials 9a, 9b ... Have a plurality of colors and the surface layer material averaging and curing steps need to be performed separately for each color, the joint pattern portion 6 is adapted to each step. By making it possible to peel off the second release paper 4 separately, both surface layer materials 9a, 9b adjacent to each other with the joint pattern portion 6 as a boundary.
The edges of each will be finished neatly and the outline of the design will be able to appear neatly.

Although the embodiment of the present invention has been described above with reference to the drawings, the specific configuration is not limited to this embodiment, and even if there are design changes and the like within a range not departing from the gist of the present invention, Included in the invention.

For example, in the examples, the case where a pressure-sensitive adhesive is used as the pressure-sensitive adhesive layer is shown, but the present invention is not limited to this.

Further, the material and thickness of each layer forming the laminated body are also arbitrary.

Further, in the embodiment, the case where the surface layer material is formed thick with a trowel is taken as an example, but the present invention is not limited to this, and for example, spray coating may be performed with a spray gun or the like.

(Effects of the Invention) As described above, in the mold for finishing the wall surface or the like of the present invention, as described above, the front surface side of the core material is subjected to the release treatment, and the adhesive agent is applied to the back surface side of the release layer. Because it has layers
The surface of the coated surface layer material by peeling the release layer from the core material surface of the laminate portion extracted for coating the surface layer material and directly adhering the release layer using the adhesive layer provided on the back surface side The masking can be performed easily and accurately, so that the laborious work of cutting out the curing sheet is not required and the work period can be shortened and the cost can be reduced.

Further, since the peeling layer of the joint pattern portion is cut in advance along with the adhesive layer on the back surface thereof substantially along the center line thereof, the surface layer material has a plurality of colors and the surface layer material is averaged or sprayed and the curing step is performed for each color. Even if it is necessary to perform the process separately, it is possible to peel off the release layer of the joint pattern portion separately according to each step, and therefore, the joint layer is adjacent to the joint pattern portion as a boundary. Both edges of both surface materials are finished neatly and the outline of the design can be made beautiful.
