Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a masonry-like or stone-clad concavo-convex pattern having two-step joints (Edo cut joints) on the walls and floors inside and outside a building. The present invention relates to a dry joint material used when forming and a method of using the dry joint material. It can be used in the construction industry or the painting industry. [0002] Conventionally, it is possible to form a two-step joint (Edo cut) masonry unevenness on the wall surface or floor surface of a building by means of troweling, spraying, rollers, etc. This is done to give the interior and exterior surfaces of the building and the floor surface a change. The conventional method will be described with reference to the plan view and the cross-sectional view of FIG. 10, and the general order of the construction methods is to apply an undercoat paint 11 which is a joint color on a wall surface (FIG. 10). B) In order to form the joint of the first step,
Affixing the joint bar 12 made of foamed plastic or cardboard ((b) in FIG. 10) On top of the joint bar, the paint of the pattern layer (referred to as the pattern paint 13) to be the second joint is applied by means such as spraying. (C of FIG. 10) Before the pattern paint 13 is cured, the surface of the hardened pattern layer is scraped off until the joint bar is completely exposed after the pattern paint is cured by a roller or the like (d in FIG. 10). A joint rod 14 made of foamed plastic or cardboard is attached to the joint portion of the step (e in FIG. 10). A pattern paint 13 is applied on the joint rod by spraying or the like (f in FIG. 10). The second step and the first step joint bar were peeled off (FIG. 10G) and the clear topcoat paint 15 was applied (FIG. 10H). It should be noted that the joint bar used in the first step and the second step has a two-layered structure, and the upper layer portion can be peeled off immediately after the pattern paint is applied, or the step can be omitted, or A method of omitting the process only in the process is also implemented. The conventional method is used to trowel a masonry-like or stone-clad concavo-convex pattern having two-step joints (Edo cut) on the inner and outer walls and floors of a building. When it is formed by means of spraying, rollers, etc., the number of processes is large and it takes a long construction period. In addition, it is difficult to carry out accurately at a construction site called thunder cut, and the finish is not good by the conventional method, which is a problem to be solved by the present invention. [0005] To solve the above problems,
The present invention provides a decorative joint sheet 4 (a combination of a base material layer and a pattern paint layer) having a first step and a second step joint portion, the surface of which is protected by a curing sheet. It is intended to solve by providing the used finishing method. As shown in FIG. 2 which is a perspective view of the appearance of FIG. 1 and a sectional view taken along the line AA of FIG. 1, the decorative joint material of the present invention includes a base material layer 1 which also serves as a joint bottom of the first step, The part of the joint on the first stage that touches the edge of the tile (temporarily called joint wall)
And a pattern paint layer 2 which forms a second joint wall, and a curing sheet 3 for forming a second joint wall portion and for protecting the surface of the decorative joint material. The base material layer 1 is made of non-woven fabric, glass cloth,
It can be obtained by coating synthetic paper or the like with synthetic resin emulsion paint or polymer cement paint using a roll coater, knife coater, or the like. Pattern paint layer 2
Can be obtained by applying a pattern paint that will form a masonry or stone-clad concavo-convex pattern in the future after curing the joint width and joint depth. However, it is also possible to integrally form the base material layer and the pattern paint layer by the method described below. FIG. 3 is a cross-sectional view of the decorative joint material thus created. Since the curing sheet of 3 is a member used for curing the pattern paint when the second joint wall is formed and the decorative joint material is actually attached to the wall surface or the like, it is a foamed plastic plate or plastic plate. , Cardboard, etc. may be used. [0008] The following methods are available to combine the constituent elements of these three decorative joint materials. First, make a base material layer first, then apply a joint stick on it and apply a pattern paint by a method such as spraying and then sand it after curing, or form the pattern paint with a knife coater to a certain thickness. After curing, there is a method in which it is cut into a predetermined size, and is attached to the base material layer with an adhesive at intervals (joint space 5) corresponding to the joint width. Further, there is a method in which a thermosetting resin is injection-molded in the form of a decorative joint sheet according to the present invention, and a pattern is formed on the joint bottom and joint wall of the first and / or second tiers by means of paint or printing. However, it goes without saying that the method is not limited to these methods. Decorative joint sheet 4 made in this way
On the other hand, by applying a curing sheet made of a foamed plastic plate or the like in a peelable state with an adhesive, a decorative joint material is completed. As a cross-sectional shape of the makeup joint material, it is also effective to have a long side inclined as shown in FIG. 4, and when the pattern paint is spray-painted, a portion of the portion where the makeup joint portion and the pattern coating material overlap each other is effective. It eliminates the steps and improves the fit. Furthermore, by applying an adhesive treatment to the back surface of the decorative joint material, it is possible to facilitate the attachment on the spot. If the joint shape or the end portion is processed as shown in FIG. 5 or FIG. 7 in order to make the pattern masonry or stone-clad using a decorative joint material, the joint becomes T-shaped. Can be processed without any problem. FIG. 5 shows a cross-sectional view when the pattern paint layer portion of the decorative joint material is cut in the layer direction, and the joint space is formed in an L shape. FIG. 6 shows a processing example of a joint intersection portion when the decorative joint material of this shape is used, by the above-mentioned sectional view. Next, in FIG. 7, similarly, a cross-sectional view of the pattern paint layer portion. Also, by forming a convex-shaped makeup joint material (b in FIG. 7), the joint intersection portions are put together. In order to actually use the makeup joint material according to the constitution of the present invention, after applying the makeup joint material in a masonry shape to the wall surface or floor surface of a building, troweling, spraying,
A second stage joint (Edo cut) can be easily formed by applying a coating material by means of a roller or the like and then immediately peeling off only the curing sheet 3 portion. In addition, when using the decorative joint material of the present invention, it is possible to finish the whole as a dry method by using a sheet-like finishing material for the wall surface and floor surface other than the joint portion. In this case, the decorative joint material portion and the other stone portion are first allocated to the wall surface or the like, and they can be attached in order to perform the construction. In the case of construction using a trowel, spray, or roller, the curing sheet 3 was required as the makeup joint material, but in the case of the dry construction method, construction is possible without it and labor saving is further improved. . Further, it is preferable to coat the surface with a clear top coat after creating Edo-cut, from the viewpoint of providing gloss or improving the durability of the entire finish coating material. By using the decorative joint material according to the present invention to form a masonry or stone-clad uneven pattern of two steps (Edo cut), the conventional method requires 9 steps. Is completed in 4 steps. This is shown in the plan view and the cross-sectional view of the drawing in FIG. 9, in which the decorative joint material 10 is applied (a in FIG. 9), the pattern paint 13 is troweled, sprayed, or painted by a roller or the like (FIG. 9B) The curing sheet is peeled off (C in FIG. 9) and the clear coating material 15 is applied (D in FIG. 9). In addition, the curing time of the paint and the polishing by the sander for smoothing the second joint area, which are the most problematic in terms of the manufacturing period, are eliminated, so that the manufacturing period is greatly shortened. EXAMPLES As the examples of the present invention, the following makeup joint materials were prepared and a construction test was conducted. For comparison, a conventional method was also used at the same place. The base material is made of glass cloth coated with the undercoat material of Formula 1 with a knife coater, and a joint bar is attached to the base material and the pattern paint of Formula 2 is applied with the knife coater. After hardening, the joint bar is peeled off and the length is 1 m, width is 40 mm, joint width of the first step is 5
mm and thickness 2 mm were used after being cut to a certain size. The construction area was 100 m ² for both the method according to the present invention and the conventional method, and a gypsum board base having openings at three locations was used. Table 1 shows the construction process and construction period. For comparison of construction speed, joint allocation was made under the same conditions. Results of construction test [Table 1] In the construction test, both the method according to the present invention and the conventional method were conducted by two persons, but the method according to the present invention halved both the number of steps and the construction period, and the construction period and the number of steps were shortened. Further, the finish feeling was almost the same, but since the joint portion (decorative joint material) of the present invention was manufactured at the factory, the thickness was uniform and the pattern was also constant. As for the method, unevenness in thickness caused by sanding and unevenness in blowing caused by spraying occurred. Next, a construction test was conducted by a dry method. The decorative joint material used was the one used in the previous test, and the portion other than the joint was a sheet-shaped natural crushed stone decoration material manufactured by Kikusui Chemical Co., Ltd. Edo cutting (joint) is colored brown granite, and other planes are colored white granite. Construction efficiency is 3 per hour
It was about ² m2, and as an Edo cut joint finish, it was efficient and beautiful. [Equation 1] [Equation 2] INDUSTRIAL APPLICABILITY A decorative joint material according to the present invention is used in a method for forming a masonry-like or stone-clad uneven pattern having a two-step joint (Edo cut) on the inner and outer wall surfaces or floor surfaces of a building. Since the process of the present invention, which is clear from the implementation test, can significantly reduce the process and the construction period, and does not require advanced technology such as smoothing by sander polishing, so that the construction is easy and the finish is good. Is.
