Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing a building made of earthen walls with black polished walls, and a space between the walls.

Conventional black polished walls are coated with an intermediate coat on the rough walls and then painted with plaster mixed in between the walls, which not only requires many open spaces between walls, but also requires a large number of spaces between the walls. Stucco takes about 6 months to 2
Since it is used after aging for a long period of 20 years, the construction period is extended and the construction cost becomes extremely high.Additionally, the plaster between the walls may rot during its aging, causing cracks and peeling on the black polished wall after construction. Many years of experience and skill were required to overcome the technical difficulties in construction.

This invention solves the above-mentioned problems in conventional black polished wall construction and develops a new wall gap.The purpose of this invention is to eliminate the need for long-term aging at all and to significantly reduce the amount of space used between walls. There is a black polished wall enforcement law that requires less.

Another object of the present invention is to provide a wall space that can be used for repair purposes by simply applying the paint to the plaster wall and then finishing it with a trowel. - The construction method of the present invention is characterized by painting and troweling the spaces between the walls immediately before drying of the plaster walls formed by a conventional method.

Furthermore, the wall gap for the construction method of the present invention is characterized by comprising a black pigment, water, and a water-soluble glue.

The details of the black polished wall construction method of this invention will be explained below.

Before forming the stucco wall, form a rough wall. The material for the rough walls is clay mixed with straw.

Next, apply an intermediate coat to the rough walls. The intermediate coating fee is pear 1'' soil,
It is assumed that the lizard is kneaded. There is nothing different from the conventional method.

Paint plaster over the intermediate coating. The material for the plaster is a mixture of slaked lime, fu, glue, and paper strips, and the thickness of the coating is approximately 1 dragon.

Next, paint is applied between the walls over the plaster, but this should be done immediately before the plaster dries, and the painting is done with a trowel, brush, spray, etc.

The amount used between walls is light so that the white background of the plaster wall is not visible, and the thinner the coating, the less peeling and the better the water resistance.

When the painted wall is about to dry, press it down with a polishing trowel to make it shine.

The black polished wall construction method of this invention is as described above, and this method differs from the conventional black polished wall construction method because it forms a plaster wall and paints the space between the walls just before the plaster wall dries. There is no need for long-term aging of the inter-wall plaster, and therefore the construction period is significantly shortened. Since this construction requires only a small amount of space between walls, construction costs can be greatly reduced, and there are excellent effects such as no special skill is required for construction.

Next, the wall spacing used in the construction method of this invention will be explained in detail.

This wall space uses carbon black as a pigment.
, and water, a water-soluble synthetic thickening agent, or a water-soluble natural thickening agent are mixed therein.

Water-soluble synthetic glues include polyvinyl alcohol, hydroxyethyl cellulose, methyl cellulose, ethyl cellulose, carboxymethyl cellulose, etc., as well as acrylic and vinyl acetate polymer compounds, but the viscosity of all of them increases as the degree of polymerization increases. A film with a low degree of polymerization is preferable because the film becomes strong and causes cracks, wrinkles, peeling, etc. on the wall surface.

Water-soluble natural glues include glue, gelatin, gum arabic,
In addition to starch, funori, alginate sorter, etc., many processed starches obtained from starch can also be exemplified.

These thickeners can be added to pigments either singly or as a composite thickener, but if too small a quantity, the dispersion of the pigment will be poor, the viscosity will drop, resulting in poor applicability, and poor adhesion to walls and gloss. On the other hand, if the amount is too high, cracks may occur on the wall due to the strengthening of the film formation.
Wrinkles, etc. occur and cause peeling.

Example 1゜Drained water 71 was prepared by dissolving 4 parts of 11y in 25 parts by weight of pigment (carbon black), adding a surfactant (nonionic) and a preservative (amine) and thoroughly kneading the mixture.
It was diluted by gradually adding parts by weight.

Example 2. (Composition only) Pigment (soot) 25 parts by weight Methyl cellulose 2 Field: ■ Active agent (nonionic) Trace amount preservative (amine type) Trace amount Water 73 parts by weight Example 3. (Composition only) Pigment (soot) 25 parts by weight Polyvinyl alcohol 3 Surfactant (nonionic type) Slight ffl preservative (amine type) m Water 72 parts by weight The interwall of this invention is as described above. The resulting product has a moderate viscosity, has good adhesion to walls, can be applied without any other contaminants, and can be finished with a beautiful gloss when pressed with a trowel, which conventional products do not have. It was easy to paint the walls with black polish, and the walls could withstand long-term storage.
