Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method of constructing surface finishing materials for houses such as single-family houses, and in particular, the present invention relates to a method for applying surface finishing materials on houses such as single-family houses, and in particular, the present invention relates to a method for applying surface finishing materials on houses such as single-family houses. The present invention relates to a method of applying a surface finishing material to finish the surface.

``Conventional technology'' In general, for industrialized houses such as single-family prefabricated houses, efforts are made to save labor and simplify on-site construction work by standardizing the frame, exterior, and interior components, etc. The interior design of industrialized housing is often left to on-site carpenter work, and the reality is that the building blocks are generally not as prefabricated and componentized as the building blocks. Therefore, parts such as floors, ceilings, and walls are limited to cases where the base is made of panels, and furthermore, the development of prefabricated interiors has been awaited for a long time.
child.

By the way, the interior of such single-family prefabricated houses, etc. includes, for example, building material boards that form the interior base that are pasted on the inner surface of wall panels, fixture parts such as fitting frames and picture frames, and wall finishing materials such as cloth. However, there was a strong demand for prefabricated boards because the building material boards that serve as the base for the interior require large-scale construction on site, and the surface finishing such as cloth after matting is also troublesome.

Conventionally, various materials have been used for building material boards that form interior foundations, but gypsum board, which is made by sandwiching cardboard on both sides of a medium-sized gypsum board, has high fire resistance, It has been widely used as an interior base material because it has good sound insulation properties, dimensional stability, excellent workability, and low cost.

By the way, these types of gypsum boards include those with holes drilled into them to serve as sound-absorbing boards, decorative gypsum boards laminated with decorative paper or plastic sheets, and waterproof gypsum boards that can be used as exterior wall materials. There are various configurations such as sheathing gypsum boards, but there have been complaints that they are less luxurious than metal siding and have poor impact resistance.

In addition, as a means to solve these problems, a metal plate (for example, 0.4 to 6 m thick) is installed on the surface of the plasterboard.
A gypsum composite board covered with aluminum plates (m-thick aluminum plates, etc.) has been proposed, but since such conventional gypsum composite boards include metal plates, their υ0 workability is poor;
In addition, it has a monotonous appearance.''Secondly, there were still problems that needed to be resolved in terms of workability and waterproofness.

"Problems to be Solved by the Invention" The present invention aims to solve the following problems in the prior art described above.

In other words, when used as a finishing material, gypsum board, which has traditionally been used as a building material, has a less luxurious feel than metal siding, and is inferior in impact resistance. Even with composite gypsum boards made by combining boards, they have poor workability, are monotonous in appearance, are time-consuming to install, and still have problems that need to be resolved in terms of waterproofing. .

The present invention was proposed in view of these circumstances, and its purpose is to improve strength, durability, water resistance, and aesthetics, as well as to facilitate construction and reduce costs. An object of the present invention is to provide a method for constructing surface finishing materials for houses.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a plate-shaped gypsum board that forms the base of the surface finishing material to be formed, and a gypsum board that covers the entire surface of the gypsum board. A method of constructing a surface material consisting of fixed stainless steel foil along the wall surface of a house, in which a material is applied in advance along the projecting corner onto the inner surface of the gypsum board facing the projecting corner of the wall surface. At the same time, a notch with a V-shaped cross section is formed so that the tip reaches the back side of the stainless steel foil, and a notch is formed that extends along the inside corner of the gypsum board facing the inside corner of the wall. A slit reaching all the way to the back side is formed, and when pasting the surface finishing material along the wall of the house, at the protruding corner of the wall, fold the stainless steel foil along the notch on the inner surface of the gypsum board. , the stainless steel foil is valley-folded at the corner of the wall, and a gypsum board as a surface finishing material is attached to the wall of the house.

In addition, in the method for applying the surface finishing material, if a plurality of notches with a V-shaped cross section are formed closely on the inner surface of the plasterboard facing the protruding corner of the wall surface, the cutouts may be formed close to each other on the inner surface of the gypsum board facing the protruding corner of the wall surface. When applying the surface finishing material, the portion of the surface finishing material located at the protruding corner can be curved into an arc, making it possible to construct the corners of the protruding corner into a gentle curve.

In addition, in the same way, if you form the grooves on the inner surface of the gypsum board facing the inside corner of the wall in a density of 'fU, when applying the surface finishing material along the inside corner of the wall, In addition, since the portion of the surface finishing material located at the inside corner can be curved into an arc shape, it is possible to form the corner of the inside corner into a gentle curve.

"Function" In the method for applying a surface finishing material according to the present invention, a surface finishing material made of a thin paper-like stainless steel foil with high malleability is adhered to the surface of a gypsum board forming a base, and this surface finishing material is By mountain-folding or valley-folding the material, it can be attached to the wall along the protruding and inward corners of the wall, making it easy to create a metallic surface finish and interior decoration on-site. can do.

In addition, walls constructed with such surface finishing materials,
Since the entire exterior surface is covered with stainless steel foil, its waterproof properties can be improved.Furthermore, the stainless steel foil supplements the strength of the gypsum board, improving the impact resistance and strength of the entire board, as well as improving its weather resistance and Durability can also be improved.

"Embodiments" Examples of the present invention will be described below with reference to FIGS. 1 to 5.

FIG. 1 is a perspective view showing a state in which the surface of a wall surface with protruding and inward corners has been finished using the method of the present invention. The processed stainless steel foil 2 is attached to the surface finishing material, which is preliminarily fixed in a factory or the like, along the panel body 3 that constitutes the wall surface W of the house, thereby improving the surface finish of the stainless steel foil 2. This section was constructed at the same time as the gypsum board l section that will serve as the interior base.

At this time, the inner surface of the gypsum board 1 facing the protruding corner of the wall surface W on the surface finishing material has a V-shaped cross section extending along the protruding corner and having a tip reaching the back surface of the stainless steel foil 2. At the same time, a plurality of slits 1b are densely formed on the inner surface of the gypsum board l facing the inner corner of the wall surface W, extending along the inner corner and reaching the back surface of the stainless steel foil 2. (See Figure 2 (a)).

In that case, the notch 1a of the gypsum board 1
The portion of the stainless steel foil 2 at the protruding corner is formed in advance into a tapered surface of about 45° on one side, so that the stainless steel foil 2 at the protruding corner is approximately 90°
'Please make sure that it can be folded in a mountain.

Here, the angle α of the notch 1a forming the tapered surface is preferably about 45° on one side in order to correspond to the angle of the protruding corner, but if the protruding corner protrudes at an obtuse angle, For example, 45 mm depending on the angle of the protruding corner.
The slope may be approximately 50° to 50' or more gently or steeply, but in any case, it should be formed into a tapered surface so that the mountain-folded part has a shape that corresponds to the protruding corner of the wall surface. It is necessary to keep it.

The specific structure of the surface finishing material A is as shown in FIGS. 3 and 4.
and a stainless steel foil 2 pasted on the entire surface of this gypsum board 1 with a blue tangent layer 4 interposed therebetween.

Here, the gypsum board 1 is constructed by using gypsum 1c as a core material, covering both sides with board base paper 1d, and forming it into a plate shape (see FIG. 3).

In addition, in the embodiment, one side 4
A notch 1a having a tapered surface of 5° is formed, and only the position where the inside corner is bent at a right angle is one slit lb.
A plurality of (six in the illustrated example) slits lb are formed at intervals in the inner corner where the inner surface is curved into an arc.

In addition, when the protruding corner part of the wall surface W is made into a curved surface curved in an arc shape as shown in FIG. This may be bent outward. With such a configuration, when applying the surface finishing material A along the protruding corner of the wall surface W, the portion of the surface finishing material located at the protruding corner can be curved into an arc shape. It becomes possible to construct the protruding corners into gentle curves.

On the other hand, the stainless steel foil 2 is made by rolling out stainless steel into a thin paper with a thickness of 35 to 50 μm, and in the example, it is embossed in a stucco shape, and is also embossed on the surface and surrounding sides of the plasterboard l. It is wrapped up to the back side of the gypsum board l so as to wrap each of them (see Figure 3).

In addition, as mentioned above, the thickness of the stainless steel foil 2 is preferably in the range of 35 to 50 μm. The reason why the thickness of the stainless steel foil 2 is set in this range is that if the thickness is less than 35 μm, the strength of the stainless steel foil 2 itself will be weakened, and if it is more than 50 μm, the stainless steel foil 2 will become too thick (and the workability will decrease and the cost will be reduced). This is because it becomes expensive.

The adhesive layer 4 that integrates the gypsum board l and the stainless steel foil 2 is made of a highly filling adhesive (
For example, epoxy adhesive, etc.) is applied to at least one of the surface of the plasterboard 1 and the back of the stainless steel foil 2, and the plasterboard 1 and the stainless steel foil 2 are overlapped. It consists of:

However, in order to actually finish the surface of a wall using this method of applying surface finishing materials, for example, when the wall surface W has no vertical unevenness as shown in Fig. 5 (a), it is necessary to Multiple slits l on the inner surface of the plaster port 1 facing the corner.
If b is formed densely, both sides of the surface finish material A are valley-folded in an arc shape, and the surface finish material A is pasted on the panel body 3 that constitutes the wall surface W. good. In addition,
When the wall surface is finished with such a configuration, when the surface finishing material A is pasted along the inside corner of the wall surface W, the part of the surface finishing material A located at the inside corner can be curved into an arc shape. This makes it possible to construct the inside corner with a gentle curve.

In addition, when forming a protruding corner part in the middle of the wall surface W as shown in FIG. 1a and slit lb are respectively formed, and when pasting the surface finish implant along the wall surface W, at the protruding corner of the wall surface, stainless steel foil 2 is placed along the notch 1a on the inner surface of the plasterboard 1. Along with the mountain folding, the stainless steel foil 2 is valley-folded at the inner corner of the wall surface W, and the gypsum board 1 as a surface finishing material is pasted on the panel body 4 constituting the wall surface W of the house. In the drawing, two surface finishing materials A are pasted along the wall surface, and their end surfaces are butted against each other to finish the surface of the wall surface (2).

In the illustrated example, when a lid 5 is attached to a position sandwiched between the protruding corners formed in the middle of the wall surface W to cover the sandwiched space, a predetermined storage space is formed here.

If such a method is adopted, by simply applying the surface finishing material A, which is made by pasting stainless steel foil 2 on the surface of the gypsum board 1 in advance, on-site, it will be possible to create the gypsum board 1, which will serve as the interior base, and create a metallic finish. A certain surface finish can be achieved at the same time.
It is possible to improve workability in interior construction work on site.

The surface finish of the wall constructed in this way is made of gypsum board, which has high fire resistance, good sound insulation, dimensional stability, and excellent workability, and is strong and water resistant. Also, since the stainless steel foil 2 with excellent weather resistance is used as the surface material, it has high durability against external forces.

In particular, since the gypsum board 1 and the stainless steel foil 2 are integrated through the adhesive layer 4 made of a highly filling adhesive, the stainless steel foil 2 will not undergo plastic deformation even if it receives an external impact. This has the advantage that the impact is alleviated, and the gypsum board 1 does not fly away due to the impact.

Furthermore, since the end face of the gypsum board 1, which forms the base of the surface finishing material A, is entirely wrapped in the stainless steel foil 2, there is an advantage that the entire building material board is water resistant.

Furthermore, the surface of the surface finishing material A can be given various shapes (for example, a stuff-like shape in the illustrated example) by embossing the stainless steel foil 2, so it has an excellent appearance. Another advantage is that the stainless steel foil itself is reinforced and can prevent dents during handling.

Note that the shapes and dimensions of each component shown in the above embodiments are merely examples, and can be variously changed based on the shape of the wall surface to be applied in the house, design requirements, etc.
