Description

Plaster finishing material and construction method inside the building using loess. {AAAAA}

The present invention relates to a construction method that can improve the difficulties, such as cracks and saggings that occur during the construction of the ocher only to improve the poor indoor environment by constructing the floor and walls of the building using the main raw material ocher and gypsum Especially in the floor construction, ocher 75%: white portland cement 25% powder ratio and water 29.4%: powder 70.6% water powder ratio to prevent cracking and increase the strength and ocher in wall construction 85.7%: slaked lime 14.3 Powder ratio of 50% and powder 50%: It prevents the cracks in the construction of the mixture and wall which produces the effects of securing strength and preventing cracks by mixing ratio of water powder ratio of 50% of water and the possibility of plastering by improving the curing speed. It is a construction method that enables plastering with a thin thickness.

1 is a cross-sectional view showing the sequence of plastering when the conventional concrete wall of the prior art.

In the prior art, since the concrete mortar (Fig. 1-a) is plastered with a cement mortar (Fig. 1-b) on a flat surface, it is finished with a wallpaper (Fig. 1-c). There was no beneficial effect on health, and the method of plastering with ocher had no way to prevent cracking, and it was impossible to apply thick thickness, so it has been used to finish in the form of blocks or panels. This was impossible and could not be popularized because of the need for additional new equipment, and the price was high.

In particular, this panel-type interior finish is sufficiently mixed with loess for the purpose of preventing cracks, soundproofing, windproofing, and heat, so that the beneficial effect of loess that is most necessary for the health of the residents who need to stay for a long time is sufficient. There was a problem that could not be conveyed.

The present invention has been devised to solve the above problems as a panel, not a panel, but by using a mesh to construct a wall, floor in a thick thickness to prevent cracking and high-strength yellow clay plastering to enable the residential environment of residents It is about how to decorate well and make it possible to install with just general plastering technique.

The characteristics of the present invention is to prevent the cracks and increase the strength with the powder ratio of ocher 75%: white Portland cement 25% and water 29.4%: powder 70.6% to improve the performance of the loess in the floor construction Ocher 85.7%: hydrated lime 14.3% powder ratio and 50% powder: 50% water powder ratio to prevent cracking and increase the strength. The reason why the floor and wall additives are different is that the floor requires higher strength than the wall.

Since the present invention is constructed by mixing according to the standardized mixing ratio as described above, it is possible to obtain the ocher effect of homogeneous quality, and it is possible to construct by the existing plastering method without the need for other equipment, so that the price is low and high quality living environment is created. You can see the effect.

<Explanation of symbols for the main parts of the drawings>

The above objects of the present invention are embodied in the detailed description based on the accompanying drawings below. 2 is a cross-sectional view showing a wall construction method and Figure 3 is a cross-sectional view showing a floor construction method.

Materials required for the wall and floor construction of FIGS. 2 and 3 are as follows.

Adhesive: The adhesive for attaching concrete, mash and loess uses mortar adhesive with concrete adhesive tensile strength over 50kg / cm ² at room temperature.

Ocher: Ocher is a red one, using only pure ones without mixing impurities, and used for filtering the walls of FIG. 2 as primary 5mm, secondary 3mm, tertiary 1mm, and for flooring in FIG. 3, primary 5mm, Use ocher filtered into 2mm 3mm and 3mm 2mm.

Mesh: The mesh uses a regular fiber mesh for dry beets (FIBER GLASS MESH # 206).

Slaked lime: Slaked lime contains more than 95% of calcium oxide, and has a specific surface area of 5000 cm2 / g.

White Portland Cement: Specific gravity 3.15 or more Unit volume weight 1500kg / ㎥ is used.

The floor and walls of FIGS. 2 and 3 are constructed by using the raw materials and materials prepared as described above. The following describes the sequence of construction methods for floors and walls.

<Wall construction method.>

1). Concrete wall cleaning and grooving process.

In order to plaster ocher (Fig. 2-⑤, ⑦) on the existing concrete wall (Fig. 2-①), if there is no half, remove the paper on the inner wall, or if there are half, remove the half and joiner completely and completely Clean.

If water and paper remain, the adhesive force is reduced, so that the water is completely dry and a groove is made with a hammer drill on the concrete surface to prevent the adhesive (Fig. 2-③) and the yellow soil from detaching from the concrete surface (Fig. 2-②). Make

2) .Material Bibimb and Kneading Process.

The finely improved material is made of ocher 75%: white Portland cement 25% powder ratio and water 29.4%: powder 70.6% powder ratio in floor construction (Fig. 3), and yellow clay 87.5% in wall construction (Figure 2). : 14.3% powder of hydrated lime and 50% powder of water: mix with 50% of water powder of water, and mix the ingredients thoroughly so that no bubbles are generated after mixing.

3) .Spray mortar glue.

Spray the mortar adhesive (MD-5000) (Fig. 2-③) on the clean concrete wall to prevent the concrete, ocher and mesh from being detached. Mortar adhesive is evenly sprayed on the concrete walls.

4) .Paste the first mesh.

Fibre GLASS MESH # 206 (FIG. 2-4) is used to make concrete and ocher completely in contact with each other, which prevents primary ocher cracks.

Since the cracks are easily generated where the mesh is not attached, it should be attached as a whole and be careful not to overlap.

5) .Apply primary ocher.

Apply ocher mixed in a proportion to a thickness of 1.5cm (Fig. 2-⑤). At first, apply roughly with a trowel, hand, or spatula, and then finish it tightly with a trowel, but be careful not to let air enter.

If a flat surface cannot be made, the trowel or plastering surface should be moistened and plastered to make it flat.

6) .Second mash.

Apply the regular fiber mesh (FIBER GLASS MESH # 206) (Fig. 2-⑥) on the flattened first plastering surface so that the secondary loess (Fig. 2-⑦) and the primary loess (Fig. 2-⑤) are completely attached. .

7) .Applying the Second Ocher

Apply secondary ocher (Fig. 2-⑦) on the secondary mash (Fig. 2-⑥) to a thickness of 1.5 cm, applying force so that it is completely in contact with the primary ocher.

8) .3rd mesh

Apply a third mash (Fig. 2-⑧) to the secondary ocher (Fig. 2-⑦) before it is completely flattened, and make the ocher completely flat after covering it with 2mm. The main effect of the tertiary mash is to prevent the loess from sagging and to prevent cracking.

9). Paste Hanji.

Paste it on the completely hardened ocher wall and apply it with Korean paper (Fig. 2-⑨) so that the paper can be completely attached. This enhances the durability of the ocher wall and prevents it from falling.

10) .Apply a badge.

Finish with paper (Fig. 2-⑩) on completely dry Korean paper.

<Yellow soil construction method.>

1). Concrete floor demolition and cleaning.

In order to place the ocher on the floor, the existing on-pipe, remaining gravel and insulation are completely removed and cleaned to prevent dust.

2) .glue foamed polystyrene.

Pay attention to the edges and use foamed polystyrene products (Fig. 3-②-①) that are not broken or damp.

3). Water vein blocking copper plate.

After the process of 2). 0.4mm copper plate is laid so that about 1cm ~ 2cm overlap (Fig. 3-③-1) to block the water absorption from the concrete and at the same time block the vein.

4). Ocher mixed powder

Lay the gravel mixed with ocher on the expanded polystyrene about 2cm ~ 4cm (Fig. 3-④-1).

5) .Install the ondol pipe and fill the primary ocher mortar.

After installing the φ12XL ondol pipe (Fig. 3-⑤-1), fill the ocher mortar with 2cm ~ 3cm to prevent the pipe from moving completely. (Fig. 3-⑥-1)

6) .Put the primary fiber mesh.

After the process of 5). In the state of the loess mortar is completely hardened, lay the normal fiber mesh (Fig. 3-⑦-1) to help the attachment of the 1st and 2nd loess mortar and prevent cracking.

7). Plastering the Second Ocher Mortar

After the process of 6) cover the ocher mortar about 2cm ~ 3cm and then roughly finish (Fig. 3-⑧-1) and be careful not to enter the air.

8). Paste secondary mesh

After attaching general fiber mesh (FIBER GLASS MESH # 206) (Fig. 3-⑨-1) to cover the ocher mortar about 1 ~ 2mm, finish the plastering completely smoothly.

9). Lay cardboard.

After the ocher plaster is completely hardened, it is laid with a floor plate (Fig. 3-⑩-1).

The ocher plastering method of the present invention constructed and acted by the above process is pleasant because it contains less impurities and is not disadvantageous in cracking or strength even if applied by plastering without applying the product made by solidifying the panel or tile in advance. It is possible to decorate a lodge's living space and have a beneficial effect on health.

The completed living space is resistant to cold, wind and noise, and you can feel the atmosphere of traditional ocher house through the unique smell and interior of ocher.
