Description

[Detailed explanation of the invention] (Industrial application field) This invention is designed to create geometric decorative joint patterns such as brick-like, ceramic tile-like, stone-like, mosaic-like patterns on the walls, floors, ceilings, etc. of buildings. This invention relates to a joint pattern forming paper pattern used when forming a joint pattern using a coating material or the like.

(Conventional technology) Building finishing methods such as brickwork and ceramic tiling have traditionally been applied to brickworks such as factory-produced bricks, ceramic tiles, and mosaic tiles, or processed and cut natural stones and artificial stones. This was done using the so-called plastering method or tile method, in which one piece or multiple pieces were pasted onto the walls, floors, ceilings, etc. of buildings, resulting in a decorative joint pattern.

However, these methods require enormous costs and construction times, so in recent years decorative wall coating materials and decorative floor coating materials (hereinafter referred to as decorative coating materials) have been developed, which create a seamless finish by applying a relatively thick layer of coating material. wood) has come to be widely used.
Although such decorative methods using decorative coating materials are effective in reducing costs and construction time, the finished product tends to be flat and monotonous.

However, today, geometric decorative joint patterns such as brick-like, tile-like, and stone-like patterns can be applied to walls, using decorative coating materials that can be applied relatively thickly using tools such as spray guns, spatulas, and trowels. A method of forming it on a floor surface, etc. is used in the industry.

As specific construction methods thereof, it is known that, for example, masking tape, joint bars, formwork, etc. are used. According to these methods, the paper and foam frame (hereinafter referred to as
Before applying the coating material, the mold material is temporarily held on the wall, floor, etc. using something like a removable adhesive, and once the coating material dries, it cannot be removed. Therefore, the coating material should be removed as quickly as possible after being applied.

A paper pattern for easily forming a geometric pattern with joints on a wall surface, etc. using a decorative coating material, and a construction method using this paper pattern have already been developed.

That is, a paper pattern formed by pasting a joint sheet with adhesive layers on both sides on a support sheet (equivalent to a mount) is pasted on a prepared wall surface, and after peeling off the support sheet, a decorative coating material is applied. At the end, the joint sheet is removed.

In addition, both sides of the support sheet serving as the mount are subjected to peeling treatment, and the adhesive force of the adhesive layer on the back side of the joint sheet is made extremely weaker than the adhesive force of the adhesive layer on the surface of the joint sheet, making it possible to overlap the paper patterns. Of course, it is possible to easily peel the support sheet from the joint sheet, and also to be able to see the marking lines written on the wall surface when pasting the pattern, and to show the vertical and horizontal centers of the pattern, as well as the vertical direction. It has already been proposed that a support sheet is provided with a notch that allows for this.

(Problems to be Solved by the Invention) These conventional paper patterns have adhesive layers on both sides of the joint sheet, so it is difficult to repair the joint sheet if it leaks on the construction surface or floats due to the influence of wind, etc. There is stickiness during the process, and the paper pattern is highly flexible, resulting in poor workability during construction. Another disadvantage is that only a small portion of the construction surface can be seen.

The present invention aims to solve these problems.

(Means for Solving the Problems) The configuration of the present invention will be specifically explained below. However, these do not limit the present invention in any way as long as the configuration of the present invention is satisfied.

Thermoplastic organic foam is the most suitable material for the joint sheet used in the present invention. This thermoplastic organic foam can be selected from any material, such as polyethylene or polyvinyl chloride, as long as it has good adhesion with adhesives or pressure-sensitive adhesives and can be molded into any shape. can.

In addition, the joint-like sheet is most preferably used with a suitable hardness in view of workability when pasting it on the joint pattern forming surface, and has a thickness of about 0.2 mm to 1.5 mm, more preferably about 0.3 mm to 1.0 mm. It is used after being punched into the desired shape.

A peelable adhesive layer is laminated on one side of the punched joint sheet, and a release treatment layer is laminated on the other side. The peelable adhesive layer and the release treatment layer are not particularly limited, and those generally used in the art can be applied.

The transparent support sheet functions as a mount for the joint sheet, but from the viewpoint of workability during pasting, it is necessary to have substantially transparency.

Specifically, sheets of polyethylene, polyvinyl chloride, etc. are used. This transparent support sheet is
When using a material with appropriate hardness as a joint sheet, it is preferable to use a material that is flexible from the viewpoint of workability, since it will be used in a laminated manner with the joint sheet.
It does not need to be as thick as a joint sheet. Further, the transparent support sheet is used in the form of a sheet without being punched, and a peelable adhesive layer is laminated on one side, and a release treatment layer is laminated on the other side. Note that there are no particular limitations on the peelable adhesive layer and the release treatment layer, and those commonly used in the art can be applied.

The joint sheet and the transparent support sheet are laminated so that the release treatment layer of the joint sheet and the peelable adhesive layer of the transparent support sheet are in contact with each other. Such an integrated joint pattern forming paper pattern can be stacked in multiple sheets, which is useful for storage or transportation.

(Example) An example of forming a joint pattern using a pattern for forming a joint pattern of the present invention will be described with reference to the drawings.

FIG. 1 shows a cross-sectional view of one embodiment of the joint pattern forming paper pattern of the present invention. a is a joint sheet made of low foam polyvinyl chloride and has a thickness of approximately 0.4 mm, b is a release treatment layer of the joint sheet, g is a peelable adhesive layer of the joint sheet, and d is made of polyethylene. , a transparent support sheet with a thickness of about 0.08 mm, c is a peelable adhesive layer of the transparent support sheet, and e is a peel-treated layer of the transparent support sheet.

FIG. 2 is a front view of the joint pattern forming paper pattern of the present invention. As mentioned above, the joint-like sheet a is used after being punched into a desired shape, and FIG. 2 shows an example of the joint pattern.

3 to 6 are cross sections taken along the line XY in FIG. 2 at each step. The construction method of the present invention will be described below in accordance with these.

FIG. 3 is a cross-sectional view taken along the line X-Y when the joint pattern forming pattern of the present invention is pasted on a base h (such as concrete) coated with an undercoat f in advance. The undercoat material must not only have normal coating performance, but also preferably has good mutual adhesion with the peelable adhesive layer g applied to the back side of the joint pattern forming paper. Of course, if the construction base is good, it is not necessarily necessary to apply a primer.

FIG. 4 shows a state in which the transparent support sheet has been peeled off from the joint pattern forming paper.

FIG. 5 shows a state in which the decorative coating material i has been applied to the entire construction surface. The material for such a decorative coating material may be cement, an aqueous dispersion of a synthetic polymer (synthetic resin emulsion or synthetic rubber latex), an inorganic polymer, or a non-aqueous dispersion as a vehicle.

FIG. 6 shows a state in which the decorative coating material i is not dried and the joint-like sheets have been appropriately removed. Thereafter, a joint-like patterned coating film is formed by sufficiently drying the coating material. Furthermore, a substantially transparent coating material (clear top coat) may be applied as a top coat material for the purpose of improving cosmetic appearance and durability.

(Effects of the invention) The invention provides the following excellent effects.

Since the support sheet for the joint pattern forming paper pattern is transparent, the joint pattern forming material can be pasted through the sheet in alignment with the marked lines on the construction surface.

The joint sheet has a suitable hardness, making it easy to apply.

After peeling off the transparent support sheet (Figure 4), the joint sheet is treated with a release treatment when spraying the coating material, so it can be repaired if the joint sheet leaks or comes loose due to wind, etc. It is also non-sticky and easy to press, and can also be pressed using a device such as a roller.
