[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing method for a projected corner and a finishing structure when the inner and outer walls or partition walls of a building are laminated with a plate material to form a wall structure. Its field of use is the construction field.

[0002]

2. Description of the Related Art Conventionally, when a plate material is attached to an inner or outer wall of a building or a partition wall to form a wall structure, a projecting corner or a entering corner is generated at a corner portion. A corner accessory made of the same material of equal side L shape, which is called an accessory, may be used at the protruding corner or the entering corner. In this case, the interaction between the accessory and the flat panel is a sealing process, and there is a design limitation. became. In addition, it is possible to cover the plate material of other flat parts by using the accessory of different members, or to use the squid head protruding corner which is a different member as the projecting corner part to butt and finish the plate members of the flat part. Was there. When the projecting corner portion is not covered with a different kind of member, it is common to fill and process the caulking at the boundary between the projecting corner accessory and the plate material of the other flat portion.

On the other hand, there is an example of a structure in which a plate material is abutted at a projected corner portion without using an accessory to perform a projected corner treatment.
It was disclosed in Japanese Patent No. 36159. In this structural example, the plate material itself has an arcuate cross-section, and is proposed to be the corner processing.

[0004]

An object of the present invention is to propose a method for treating a projected corner with a decorative plate having a thick paint layer on a flat plate material regardless of the sectional shape of the plate material.

[0005]

In order to achieve the above object, the following matters are the gist of the present invention. According to the invention of claim 1, a decorative board having a thick paint layer on its surface is
When sticking to the two surfaces that make up the projecting corner part, make sure that each side of the two decorative plates that stick to both sides of the projecting corner line is on the projecting corner side and that the surface side is an acute angle. Cut or scraped so that it becomes the projected corner angle when the two decorative boards are abutted, apply the adhesive to the end face, and stick the two decorative boards in the projected corner part in a protruding state and squeeze out This is a method for treating a projected corner, which is characterized by scraping off excess adhesive.

According to a second aspect of the invention, there is provided a method for treating a projected corner, characterized in that the thick paint layer according to the first aspect is formed by coating a decorative plate.

According to a third aspect of the invention, there is provided a method for treating a projected corner, characterized in that the thick paint layer according to the first aspect is formed by adhesion to a decorative plate.

According to a fourth aspect of the present invention, the thick coating layer according to the third aspect has a reinforcing material layer, which is formed by adhesion to a decorative board. It is a processing method.

In a fifth aspect of the present invention, the base material to be the decorative plate according to the first aspect is ceramic siding.
It is the processing method of the projected corner described in 3 or 4.

According to a sixth aspect of the present invention, a decorative plate having a thick paint layer on its surface is attached to the projecting corner of the building structure in such a manner that cut surfaces are abutted at the projecting corner. It is a finishing structure.

The individual elements constituting the present invention will be described below. The base material to be the decorative plate according to the present invention,
Although an example is described in claim 5, in addition to ceramic siding, extrusion molded cement board, gypsum board, wood plywood,
It can also be used as a base material for forming a wall structure in pulp cement boards, fiber boards, particle boards and the like. 199
According to JIS A5422 revised in 5 years, asbestos cement siding, asbestos slate, fiber reinforced cement board, asbestos cement perlite board, which is the JIS before that,
Asbestos cement calcium silicate board, JIS for slag / gypsum cement board, etc. are integrated into ceramic siding. In the present invention, siding made of these various materials or those containing various commercially available characteristic components are referred to as ceramic siding.

A paint suitable for forming a thick film paint layer is a natural stone or crushed stone thereof, colored aggregate, colored plastic particles, plastic crushed particles or glass beads as an aggregate, synthetic resin emulsion, solvent type synthetic resin, The main component is a binder such as hot melt resin. The particle size of the aggregate is selected from those having a particle size of about 0.01 to 3.0 mm. As the synthetic resin component used for the binder,
Known materials are appropriately used, and examples thereof include acrylic resin, vinyl acetate resin, vinyl chloride resin, urethane resin, silicon resin, polyester resin and the like. The mixing ratio of the aggregate and the binder is selected according to the physical properties and appearance of the coating layer, the coating thickness, etc. For example, in the weight ratio, the solid component weight of the aggregate component and the binder is 70:
It is appropriately selected from the range of about 30 to 95: 5.

By coating the coating material containing these components on the base material of the decorative plate directly or via a primer, a coating layer was formed or a thick film layer containing only the coating material was formed on the release paper. After that, glue it on the base material of the decorative board,
An example is a method in which a coating material is applied on a reinforcing material such as a non-woven fabric, glass cloth, or synthetic paper, an integrated material of the reinforcing material and a paint layer is once created, and then the composition is adhered onto the base material of the decorative plate.
Examples of paint layer formation include painting with a single-head or multi-head spray gun in building painting, roller, trowel coating, knife coater, roll coater coating, and depending on the other properties of the coating, It is possible to form a paint layer by extrusion molding. In the present invention, the condition is that the paint layer is formed into a thick film for use, but the thickness is about 0.5 mm to 4 mm. When the thickness is thin, the end faces of the base material will appear on the projected corner surface when the decorative plates are joined by being stuck together. Further, when the thickness is thicker than 4 mm, no particular problem occurs, but the cost for the coating material increases and the practicality is lacking. For this paint layer,
In order to improve the durability of the paint layer or the decorative plate, it is of course possible to further apply a transparent protective paint for use. Examples of protective paints include those containing acrylic resin, urethane resin, fluororesin, and acrylic-silicone resin as main components.

Known adhesives are used as the adhesive used when the thick paint layer is prepared in advance and is adhered to the base material of the decorative board. Examples thereof include vinyl acetate resin type, acrylic resin type and synthetic type. Various adhesives such as rubber and acrylic rubber are used.

A procedure for applying a decorative plate having a paint layer of a coating film to the projected corner will be described with reference to the drawings. First of all, each veneer that will be attached to the two surfaces that make up the projecting corner is processed in advance. The processing is performed by cutting or scraping each of the sides of the decorative plate, which are in contact with the projecting corner line, so that the surface side has an acute angle and the projecting plate has a projecting angle when the two decorative plates are butted. And
After processing, after applying adhesive to the end faces that are abutted at the protruding corners of the decorative material, or after attaching one plate to the protruding corners of the wall surface, apply an adhesive to the abutting end faces and then Stick the decorative boards on both sides of the corner line.

The decorative plate is fixed to the wall portion by a method of hitting with a metal object such as a stainless steel nail or a screw nail, which is generally used in the conventional method, or a method of fixing with a metal fitting which has been increasing in recent years. There is. When nails or the like are driven in from the surface of the decorative plate, if these become a design problem, the nail head or the like may be repaired with a paint of the same quality and color as the paint used for forming the paint layer. Of course, it is also possible to use a nail in which the entire nail or the nail head has the same color or a similar color to the paint of the decorative plate.

The decorative plate attached to the projecting corner is as it is, or the adhesive that squeezes out at the projecting line is also scraped off together with the decorative paint, or only the scraped off part or the entire surface of the decorative plate is transparent. Finish by painting with a protective paint. At this time, even if the projected corner line is scraped off due to the thickness of the paint being several mm, the inside of the thick-film paint, which has the same color, appears on the surface, and the paint forms a continuous decorative surface. Give a feeling.

As the adhesive to be applied to the end face of the decorative corner of the decorative plate, the same adhesive as the adhesive for adhering the thick paint layer to the base material of the decorative plate can be used. But,
In this case, it is preferable to select one that has no possibility of yellowing due to sunlight when actually used, and one that has a small cohesive force of the adhesive itself.

In FIG. 1 of the drawings, the steps up to the processing of the decorative plate and the finishing of scraping off the ends of the projecting corner lines are schematically shown in the cross section of the projecting corner lines. In the example of FIG. 1, it is planned to finish the decorative board by laying it horizontally. In (a) of FIG. 1, two decorative plates have been prepared for the pillar portion of the projecting corner. In the figure, reference numeral 1 is a pillar, 2 is a vertical furring strip, 3 is a decorative plate, and 5 is a stud. In (B) of FIG. 1, each of the decorative plates is aligned with the position of the projected corner line and is cut off so that the surface side has an acute angle. In the figure, it is understood as cutting with a saw, but the actual cutting is often done with a circular saw, and it is processed with the decorative plate placed sideways. At this time, the projecting corner line is defined with reference to a boundary line inside or on the surface side of the decorative plates formed when the decorative plates are butted. In the figure, reference numeral 6 is a cutting tool.
In (c) of FIG. 1, one of the decorative plates whose end portions have been processed is attached to the projected corner portion, and an adhesive is applied to the end portions. In the figure, reference numeral 7 is an adhesive. In (d) of FIG. 1, the excess adhesive protruding from the abutting end faces of the projecting corners is being scraped off with a grindstone. In the figure, reference numeral 8 indicates a grindstone. In some cases, a transparent protective paint may be applied to the scraped part of the paint layer surface after scraping off the part where the adhesive has squeezed out. Although not shown in the figure, waterproof paper is generally attached to the inside of the furring strip prior to attaching the decorative plate.

FIG. 2 is an enlarged view of the column portion of the projecting corner in the example of FIG. In the figure, a vertical furring strip 2 is attached to a pillar 1, and a decorative plate 3 is attached thereon. The decorative board is formed of the base material 3a and the paint layer 3b.

FIG. 3 is a view showing the pillar portion of the projecting corner by a transverse section of the projecting corner line when the decorative board is vertically stretched and finished.

EXAMPLES Examples of the present invention will be described below.
The following table 1 shows a simple table of the main constitutions in the examples. The method of applying the decorative plate, the method of fixing (fixing), the repair of the nail head, the method of forming the paint layer, and the reinforcement in the paint layer. The presence or absence of timber layers is summarized.

[Table 1]

In Example 1, a commercially available ceramic siding board, a slag cement perlite board, a board having a size of about 2730 × 450 mm × thickness of 12 mm was used as the base material of the decorative board. To this siding plate, a paint according to the following formulation 1 was prepared in order to form a paint layer, spray-coated so as to have an average thickness of 3 mm, and dried.
Incidentally, the siding plate was cured so that the paint did not adhere to the actual processed part.

Composition 1 Acrylic synthetic resin emulsion (N.V = 50%) 25 parts by weight Colored fine aggregate (dark brown: light brown: white = 5: 5: 50) 60 parts by weight Addition of thickeners and the like Agent 5 parts by weight Water 10 parts by weight ─────────────────────────────── Total 100 parts by weight

The obtained decorative board is cut into half lengths,
On the other hand, a model of the projecting corner part of the wooden frame structure was created and the pasting test was conducted. Laminate the decorative plate horizontally and cut the end face in the short side direction of the abutting part in the short side direction at an angle of about 45 degrees (angle from the surface side), and cut it on one side of the short side. The same number was machined so that both sides of the corner could be configured. The vertical furring strips were assembled so as to be orthogonal to the corner pillars, and the decorative board was attached by nailing so that the processed portion of the decorative platter was aligned with the projected corner portion of the furring strip. Subsequently, the other decorative plate was applied with an acrylic resin adhesive on the end face of the projecting corner line, and then the end face was butted to the furring strip. The nails were made of stainless steel, and the nail head was covered with a tube of thick film paint. The finished corner model has a continuous paint layer.

In Example 2, the base material of the decorative board was a commercially available slag cement perlite board, and the size was 1820 × 450 ×.
Example 1 was prepared by using a four-sided sheet having a thickness of 15 mm as a base.
A model of a wooden frame structure was created using a decorative board coated with the same paint as above, and a sticking construction test was conducted. One of the purposes in the second embodiment is to confirm the finished state of the projected corner portion. Second, in the past, when the work was started from the projecting corner, the work was started from the projecting corner, and when the construction was started, the design of the flat surface was emphasized. This is to perform the process of (adjustment of the half part of the allocation). Of course, at this time, the normal corner flat panel was used to finish the corner outside without sealing the mating of the corner and the flat panel. The decorative board was laid horizontally, the construction was started according to the layout design of the flat panel, the size of one sheet on the projected corner was measured, and the panel was cut out at an angle of 45 degrees (angle from the surface side). At this time, the dimension of the surface side must be cut larger than the projected corner line by the vertical furring strip by the thickness of the decorative plate. In addition, the panels attached to the opposite side so that both sides of the projected corner can be configured were also cut according to the layout. At this time, the cut side must consider the actual competition with the next panel. The vertical furring strips were assembled on the pillars in the corners so that they were orthogonal to each other, and the processed parts of the decorative plate were aligned with the projected corners of the furring strip, and the decorative plate was fixed using fastening brackets. . Subsequently, the other decorative plate was applied with an acrylic resin adhesive on the end face of the projecting corner line, and then the end face was abutted and fixed to the furring strip by using a fastener. After the adhesive applied to the exposed corners has hardened, the adhesive that oozes out is peeled off and the finish feeling is confirmed. The material was not exposed and the finish was good. In addition, the projected corner was non-caulking, and a sense of unity was obtained between the flat surface and the projected corner.

In Example 3, a commercial calcium silicate board was used as the base material of the decorative board, and the size was about 910 × 450 mm ×.
12 mm was used. For this siding plate, a polyester non-woven fabric was used as a reinforcing material to form a paint layer, which was sealed with an emulsion paint, and the paint was manufactured by Kikusui Chemical Co., Ltd. under the trade name China Tone and color number CT-2. Was coated at 3 kg per m ² and dried to prepare in advance, which was adhered onto a substrate. The non-woven fabric used as the reinforcing material has a basis weight of 50 g, and the emulsion coating material for sealing is a gray color coating material in which 70% of PVC of the coating material is blended by using styrene-acrylic resin as a resin component. China-tone CT-2, which is the paint layer, is composed of three colors of paint (skin-based finish coating material), and is composed of white paint 1A, gray color, black sesame paint 2B, and pink light color paint 2C. . Further, 1A color contains only cold water sand in the aggregate component, 2B color contains cold water sand, black colored cold water sand, light gray colored cold water sand in the aggregate component, and in 2C color, The aggregate component contains cold water sand and light brown colored cold water sand. The paint layer having the reinforcing material layer was attached to the base material with an acrylic resin adhesive.

Prior to attaching the obtained decorative board, the corner pillars and studs in the wooden frame structure are erected in the same manner as in the previous example, and the corner pillar angles are set vertically so that the decorative board can be vertically installed. We created a foundation with horizontal furrows attached to connect furrows and pillars to studs. On the other hand, one side in the long side direction of the decorative plate was cut so as to form an angle of 90 degrees when the plates constituting the two surfaces were butted, and an angle of approximately 45 degrees from the surface side. For attachment, nailing was done by using stainless steel nails, and only the nail heads were touched up using the same paint as for the makeup part. In this case as well, since the coating film was a thick film, the nail was driven to the base material using a punch, and then repaired, resulting in a good finish. An acrylic resin-based adhesive was used for the end surface of the decorative plate, and the adhesive was applied to the decorative plate on one surface after the adhesive was applied, and the adhesive was applied so that the decorative plate on the other surface was abutted before curing. After the adhesive was hardened, the corners of the projected corner were polished with a grindstone to give a rounded finish.

[0029]

According to the method of the present invention, an apparently continuous wall structure can be obtained even in the projecting corner portion without being restricted by the design. Further, the size of the decorative plate attached to the projected corner portion can be freely determined within the range of the size of the decorative plate constituting the other flat portion, unlike a normal projected corner accessory. Considering the agreement, the surface exposure of the caulking portion of the portion that connects the accessory and the flat portion, which occurs when the corner accessory of the same material is used, is eliminated.
Further, it becomes possible to finish the flat surface portion and the projected corner portion without separately preparing an accessory.
