Description

  The present invention relates to a decorative outer wall material disposed on an outer wall of a building and a construction method thereof.

  A decorative outer wall material is applied to the outer wall of the building for the purpose of improving the design. As a decorative outer wall material, an ALC panel made of lightweight cellular concrete that is lightweight and has good workability is often used. Since this ALC panel is made of a porous material and has high water absorption, a panel that has been subjected to a decorative coating after a waterproof coating is often used.

  Moreover, there exists an ALC panel shown by patent document 1 other than the makeup | decoration outer wall material which gave waterproof coating and makeup | painting coating, for example. In Patent Document 1, an ALC panel is disposed on the outer wall of a building, and then a surface sheet material is attached to the surface of the ALC panel. The surface layer sheet material has a sheet-like base material and a waterproof paint layer formed on the surface of the sheet-like base material.

JP-A-8-4250

However, the above-described decorative outer wall material has the following problems.
Since the ALC panel is a porous material and the surface is not smooth, the workability of the painting work is not good. Therefore, depending on the skill level of the painter, differences in the finish of the paint are likely to occur, and high paint technology is required to ensure the paint quality. Also, the drying time is required for the waterproof coating and the decorative coating, respectively, and the work efficiency is lowered.

  In order to improve the work efficiency of painting, it is possible to paint the exterior wall material in the factory. However, when a painted exterior wall material is overlaid for storage and transportation in a factory, the coating layer tends to stick. Therefore, there is a possibility that poor coating such as peeling or scratching of the coating may occur. In addition, the decorative outer wall material can be overlapped through a buffer sheet made of a material that is difficult to stick to the coating layer, but the work of arranging the buffer sheet and the cost of the buffer sheet are required.

  In Patent Document 1, a waterproof paint layer is provided in advance on a cover sheet material to be attached to an ALC panel. Therefore, by superimposing the cover sheet material, the sticking of the coating occurs, and there is a risk that the coating failure such as peeling or scratching of the coating may occur as in the case of the exterior wall material that has been previously painted.

  The present invention has been made in view of the above background, and intends to provide a makeup outer wall material having excellent coating quality and a method for constructing a makeup outer wall material that can be easily constructed. is there.

One aspect of the present invention includes a mounting surface disposed toward a building, a design surface disposed opposite to the mounting surface, a side surface connecting the mounting surface and the design surface, and a lightweight bubble. A core panel made of concrete;
A resin sheet attached to cover the core panel,
The resin sheet is affixed so as to cover at least the entire design surface, the entire side surface, and a part of the mounting surface of the core panel by stretching one sheet.
A decorative outer wall material is characterized in that a coating layer formed by applying a paint is provided on at least the resin sheet on the entire surface of the design surface.

Another aspect of the present invention is a method for constructing a decorative outer wall material,
Prepare a spare outer wall material with a resin sheet attached to the core panel,
In the construction method of a decorative outer wall material, the preliminary outer wall material is attached to the outer wall surface of a building, and a coating layer is formed by applying a paint to the surface of the preliminary outer wall material.

  The decorative outer wall material includes the core material panel, the resin sheet attached so as to cover the core material panel, and a coating layer formed by applying a paint on the resin sheet. Therefore, the coating quality in the said exterior wall material can be improved.

  That is, in the decorative outer wall material, the resin sheet serves as a base by covering the core panel with the resin sheet. The resin sheet that is stretched and stuck to the core panel covers a hole formed on the surface of the core panel, and forms a smooth surface on the core panel. . Therefore, the coating layer can be formed on the resin sheet without being affected by the surface properties of the core panel. Thereby, the said coating-film layer can be formed easily, without performing the waterproof coating conventionally required.

  The coating layer is formed by applying a paint on the resin sheet. Therefore, the time for forming the coating layer can be appropriately selected. For example, the coating layer may be formed in a state where the core panel covered with the resin sheet is attached to the outer wall, or after the coating layer is formed in a state before being attached to the outer wall. It may be attached to the outer wall.

  Moreover, the said resin sheet can be formed with the raw material which is hard to stick together even if it piles up. Therefore, even if the said core material panel covered with the said resin sheet is piled up, sticking can be prevented. Therefore, the resin sheet can be affixed to the core panel efficiently in a place equipped with facilities such as a factory and can be transported to a construction site. Therefore, it is possible to improve the production efficiency, cost reduction, and quality of the decorative outer wall material, and to further reduce the amount of work at the construction site.

Furthermore, the surface properties of the resin sheet are much smoother than the lightweight cellular concrete that forms the core panel. Therefore, by forming the coating film layer on the resin sheet, a high-quality coating film layer having a sense of transparency and gloss can be obtained.
Thus, according to the said exterior wall material, a high-quality coating film layer can be obtained easily.

  Further, in the construction method of the decorative outer wall material, the preliminary outer wall material is prepared, the preliminary outer wall material is attached to the outer wall surface of the building, and a paint is applied to the surface of the preliminary outer wall material to form a coating layer. To do. Since the said external sheet | seat has affixed the said resin sheet to the said core material panel previously, waterproof coating can be abbreviate | omitted. Therefore, the amount of work at the construction site can be reduced.

  Moreover, the said resin sheet can be formed with the raw material which is hard to stick together even if it piles up. Therefore, even when the preliminary outer wall material is overlapped during storage and transportation in a factory, sticking between the overlapping preliminary outer wall materials can be prevented. Therefore, even if the preliminary outer wall material is overlaid, the resin sheet is less likely to be defective in the preliminary outer wall material. Thereby, the said resin sheet can be affixed to the said core material panel efficiently in the place where facilities, such as a factory, were prepared, and can be conveyed to a construction site. Therefore, it is possible to improve the production efficiency, cost reduction, and quality of the spare outer wall material, and to further reduce the amount of work at the construction site.

  As described above, it is possible to achieve excellent coating quality with the decorative outer wall material, and to easily construct the building by the construction method of the decorative outer wall material.

  In the decorative outer wall material, the coating layer is preferably formed on a primer layer provided on the surface of the resin sheet. In this case, the adhesion between the resin sheet and the coating film layer can be improved, and color unevenness and peeling in the coating film layer can be prevented.

  The design surface of the core panel may be an uneven design surface having an uneven shape. In this case, the design freedom in the design surface can be improved. Therefore, the design of the decorative outer wall material can be improved.

  In addition, the resin sheet is arranged in a state where no cuts are provided and connected in a range covering the entire design surface, the entire side surface, and a part of the mounting surface of the core panel. Also good. In this case, since the resin sheet is not cut, the design of the decorative outer wall material to which the resin sheet is attached can be further improved. Moreover, since the resin sheet covering the core panel has no breaks, the reinforcing effect of the resin sheet can be improved.

  The preliminary outer wall material may include a primer layer provided on the surface of the resin sheet. In this case, the coating operation can be easily performed by previously forming the primer layer on the surface of the resin sheet. In addition, it is preferable to select a primer layer that does not easily stick after drying. In this case, sticking of the primer layer can be prevented when the preliminary outer wall material on which the primer layer is formed is overlapped. Therefore, the primer layer can be efficiently formed in a factory or the like.

(Example 1)
The Example concerning the said exterior wall material is described with reference to FIGS.
As shown in FIGS. 3 and 4, the decorative outer wall material 1 includes a core panel 2 made of lightweight cellular concrete, and a resin sheet 3 attached so as to cover the core panel 2. The core panel 2 includes an attachment surface 21 that is disposed toward the building, a design surface 22 that is disposed opposite to the attachment surface 21, and a side surface 23 that connects the attachment surface 21 and the design surface 22. Yes.
A single resin sheet 3 is stretched and attached so as to cover at least the entire design surface 22, the entire side surface 23, and a part of the mounting surface 21 of the core panel 2.
A coating layer 4 formed by applying a paint is provided on the resin sheet 3 on the entire design surface 22 and the entire side surface 23 of the decorative outer wall material 1.

This will be described in more detail below.
As shown in FIGS. 3 and 4, the decorative outer wall material 1 includes a core material panel 2, a resin sheet 3 covering the core material panel 2, a primer layer 5 formed on the surface of the resin sheet 3, and a primer layer 5. And a coating layer 4 formed on the surface.
The core panel 2 includes an attachment surface 21 that is disposed toward the building, a design surface 22 that is disposed opposite to the attachment surface 21, and a side surface 23 that connects the attachment surface 21 and the design surface 22. Yes. The design surface 22 and the attachment surface 21 are connected by a side surface 23 formed of a plane. The design surface 22 includes a concavo-convex design surface 221 formed with a quadrangular pyramid-shaped concavo-convex shape.

  The core panel 2 is made of lightweight cellular concrete. Lightweight cellular concrete refers to Autoclaved Lightweight aerated Concrete (ALC). As shown in FIGS. 1 and 3, the core panel 2 has a design surface 22 of a flat base plate having a rectangular shape having a long side length L, a short side length W, and a plate thickness t. The concave and convex design surface 221 is formed by cutting. In this example, the distance between the top surface of the concavo-convex shape of the concavo-convex design surface 221 and the mounting surface 21 is the plate thickness t. Further, the uneven shape has a substantially square frustum shape arranged on the uneven design surface 221 in a long side direction parallel to the long side and a short side direction parallel to the short side. The bottom surface of the concavo-convex shape is a rectangle, and the top surface of the concavo-convex shape is a rectangle obtained by reducing and projecting the bottom surface. The uneven shape is not limited to the substantially square frustum shape, and can be formed in various shapes.

  As shown in FIGS. 1 to 4, the resin sheet 3 is made of a vinyl chloride resin, and in a state before being attached, a rectangle obtained by enlarging and projecting the outer shape of the core panel 2 viewed from a direction orthogonal to the concave and convex design surface 221. There is no. In addition, what is necessary is just to set the magnitude | size of the resin sheet 3 according to the dimension of the core material panel 2 suitably. The resin sheet 3 is a material that does not stick to the resin sheets 3 and the core material panel 2. However, it is naturally possible to attach the resin sheet 3 to the core material panel 2 or the like by using an adhesive or the like.

  In this example, the resin sheet 3 was attached to the core material panel 2 using a vacuum molding machine (not shown). On the table arranged in the chamber box of the vacuum forming machine, the core material panel 2 coated with an adhesive is disposed on the entire design surface 22, the entire side surface 23, and the vicinity of the outer peripheral edge of the mounting surface 21. At this time, the core material panel 2 is arranged in a state where the outer peripheral end portion is floated. In the chamber box, the resin sheet 3 is disposed above the core panel 2, and the space in the chamber box is vertically divided into two by the resin sheet 3 so that the upper and lower spaces are sealed. After the resin sheet 3 is heated by a heater to be easily stretched, the lower space where the core material panel 2 is arranged is evacuated so that the resin sheet 3 adheres to and is attached to the core material panel 2.

  At this time, even in the corners and the uneven shape of the core panel 2, the resin sheet 3 is applied while being stretched along the shape, so that wrinkles and the like do not occur. In addition, the resin sheet 3 is arranged in a state in which notches are provided and connected in a range that covers the entire design surface 22, the entire side surface 23, and a part of the mounting surface 21 of the core panel 2. Yes. Moreover, the resin sheet 3 can be affixed to the attachment surface 21 of the core material panel 2 by arrange | positioning in the state which floated the edge part of the core material panel 2. FIG. In addition, in the decorative outer wall material 1 of this example, as shown in FIGS. 1 and 2, the entire surface of the design surface 22, the entire surface of the side surface 23, and the range from the outer contour of the mounting surface 21 to the inner position are resin sheets. 3 covered. Since the resin sheet 3 does not transmit moisture, it functions as a waterproof layer in addition to the role of the base layer, and can prevent water from entering the core panel 2.

As shown in FIGS. 3 and 4, the primer layer 5 and the coating layer 4 are formed on the surface of the resin sheet 3 that covers the core panel 2.
The primer layer 5 is formed by applying a primer on the resin sheet 3 on the entire design surface 22 and the entire side surface 23. In this example, a one-liquid quick-drying primer is used for the primer layer 5, and the primer layer 5 was formed in advance at the factory. In addition, a primer is not restricted to this, A good thing can be selected suitably according to the material of the resin sheet 3, and the kind of coating material which forms the coating-film layer 4. FIG. However, when the primer layer 5 is formed in advance in a factory, it is more preferable that the primer layer 5 is difficult to stick to a portion that contacts when the formed primer layer 5 is overlapped.

  As shown in FIGS. 1 to 4, the coating layer 4 is formed on the primer layer 5 formed on the resin sheet 3 on the entire surface of the primer layer 5, that is, the entire surface of the design surface 22 and the entire surface of the side surface 23. It is formed by coating. In this example, a one-component water-based acrylic silicone paint is used as the paint for forming the coating film layer 4, and the coating film layer 4 was formed at the construction site of the building. In addition, the coating material which forms the coating-film layer 4 is not restricted to this, A various coating material can be selected in consideration of a weather resistance, compatibility with the primer layer 5, etc.

  That is, in the decorative outer wall material 1, the resin sheet 3 serves as a base by covering the core material panel 2 with the resin sheet 3. The resin sheet 3 that is stretched and stuck on the core material panel 2 covers the hole formed on the surface of the core material panel 2 and forms a smooth surface on the core material panel 2. . Therefore, the coating layer 4 can be formed on the resin sheet 3 without being affected by the surface properties of the core panel 2. Thereby, the coating-film layer 4 can be formed easily, without performing the waterproof coating conventionally required.

The coating layer 4 is formed by applying a paint on the resin sheet 3. Therefore, the time for forming the coating layer 4 can be selected as appropriate. For example, the coating layer 4 may be formed in a state where the core panel 2 covered with the resin sheet 3 is attached to the outer wall 6, or the coating layer 4 is formed in a state before being attached to the outer wall 6. After that, it may be attached to the outer wall 6.

Therefore, the production efficiency of the decorative outer wall material 1 can be improved, the cost can be reduced, and the quality can be improved, and the amount of work on the construction site can be further reduced.

  Furthermore, the surface properties of the resin sheet 3 are much smoother than the lightweight cellular concrete that forms the core panel 2. Therefore, by forming the coating film layer 4 on the resin sheet 3, it is possible to obtain a high-quality coating film layer 4 having transparency and gloss.

  In the decorative outer wall material 1, the coating layer 4 is formed on the primer layer 5 provided on the surface of the resin sheet 3. Therefore, the adhesiveness between the resin sheet 3 and the coating film layer 4 can be improved, and color unevenness and peeling in the coating film layer 4 can be prevented.

  Moreover, the design surface 22 of the core material panel 2 consists of the uneven | corrugated design surface 221 which exhibited uneven | corrugated shape. Therefore, the degree of freedom of design on the design surface 22 can be improved. Therefore, the designability of the decorative outer wall material 1 can be improved.

  In addition, the resin sheet 3 is arranged in a state in which notches are provided and connected in a range that covers the entire design surface 22, the entire side surface 23, and a part of the mounting surface 21 of the core panel 2. Yes. Therefore, since the resin sheet 3 covering the core panel 2 is not cut, the reinforcing effect of the resin sheet 3 can be improved. Therefore, even when the core material panel 2 is damaged, the shape can be more reliably maintained. Moreover, since there is no cut in the resin sheet 3, the designability of the decorative outer wall material 1 to which the resin sheet 3 is attached can be further improved.

  As described above, according to the decorative outer wall material 1 of this example, excellent coating quality can be realized.
