These materials have been widely and generally adopted mainly as a result of efforts to improve internal strength and cost.

を傷めたりすることがおることは、周知の事実でおる。Problems to be Solved by the Invention The biggest drawback of concrete as an interior and exterior material is that it inevitably condenses on its surface when the indoor temperature drops. This is said to be due to the poor quality of concrete. In other words, when the indoor air temperature drops beyond the dew point, a large amount of water droplets adhere to the concrete surface and run down, staining the wall surface or damaging objects placed in contact with the wall surface. It is a well-known fact that this is the case.

年になって、その発癌性の問題がクローズアップされた
ため、従来の優位性を急速に失いつつおる。In addition, mineral fibers such as asbestos and rock wool are rapidly losing their traditional superiority due to the carcinogenicity of these mineral fibers being highlighted in recent years.

がない。On the other hand, earthen walls or plaster walls are porous and have a low heat transmission rate, and they also have the ability to breathe moisture, so the occurrence of surface condensation is extremely rare. The cost becomes excessive because of the need for skilled workers.
Currently, it is rarely used except in special buildings.

ことにおる。Therefore, in view of the actual situation and problems of the prior art, the purpose of the invention of this application is to contain diatomaceous earth so that the porous nature of diatomaceous earth can extremely effectively suppress the occurrence of surface condensation. It has excellent fire resistance and heat insulation properties, is safe for the human body, and can be applied by spraying as well as troweling, so it can be easily installed even without special skilled workers. The purpose of the present invention is to provide a new dew-proof and fire-resistant coating material for buildings and a method for its construction.

石膏は、一般に市販されているものでよい。The plaster may be one that is generally commercially available.

In addition, examples of pearlite include, for example, powder "Pearlite Type ■" manufactured by Ube Industries, Ltd., or granular "Atsuba Light No. 3" and "Perlite No. 4" manufactured by Asano Cemen Co., Ltd. -1, "M-2" can be used.

図る目的のものであるが、多過ぎるときは断熱性が不足
し、少な過ぎるときは強度が不足する。If the amount of calcined powder on diatoms is too small, the dew-proofing and heat-insulating properties will decrease, and if it is too large, the dew-proofing and heat-insulating properties will improve, but the finished strength and adhesion will decrease. Gypsum is used to harden the diatom surface and improve the strength of the finish, but if it is too little, the strength will decrease, and if it is too much, the dew resistance will decrease. A soil hardening agent is used to improve strength and adhesion, but if too much is used, the dew resistance decreases and cracks tend to occur more easily. The purpose of granulated blast furnace slag, along with a soil hardening agent, is to improve strength and adhesion; however, if there is too much, the insulation properties will be insufficient, and if there is too little, the strength will be insufficient.

ない。Pearlite improves fire resistance, and in particular, granular pearlite is highly cellular, so it is useful not only for fire resistance but also for improving heat insulation. Therefore, the pearlite may be only in powder form, only in granule form, or an appropriate mixture of both. If there is too much pearlite, the strength will be insufficient, and if there is too little pearlite, sufficient fire resistance and heat insulation properties will not be obtained.

。Water is added to the mixture of each of these components, kneaded to an appropriate consistency, and then applied to the base material by troweling, spraying, or any other method depending on the construction conditions and drying. Then, it can be used as a fireproof coating. The coating thickness at this time is preferably about 5 to 60 mm for interior construction, and about 4 to 30 mm when applied to an external wall as external heat insulation, depending on the required fire resistance time.

効果がある。On the other hand, according to the second invention of this application, the dew-proof and fire-resistant coating material for buildings according to the first invention can be easily applied, and moreover, there is a gap between the second upper layer and the base material. Since the first layer is mixed with a heat-resistant binder to improve adhesion to the underlying material, it has the excellent effect of providing an extremely robust interior and exterior finish.
実施例
以下、実施例を示すが、この出願に係る発明は、以下の
実施例に限定されるものではない。EXAMPLES Examples will be shown below, but the invention according to this application is not limited to the following examples.

露性・耐火性・断熱性に優れた丈夫なものでおり、且つ
、下地材料からの耐剥離性も充分でめった。Example (2) A heat-resistant binder and water were mixed with the dew-proof and fire-resistant coating material for buildings according to the previous example, and after stirring well, a first coat with a thickness of 1M was sprayed onto a base material made of iron plate. Layers were constructed. Thereafter, only water was mixed with the fireproof coating material of the previous example, and after stirring, a second layer was formed by overlaying the first layer and spraying. The thus obtained wall surface was durable with excellent dew resistance, fire resistance, and heat insulation, and also had sufficient peeling resistance from the base material.
実施例（３）
実施例（１）において、耐火被覆材料を構成する各成分

範囲で変更したときも、防露性と耐火性と断熱性とを保
有する壁面を形成することができた。Example (3) In Example (1), the amounts of each component constituting the fireproof coating material were changed to 5% to 95% of fired diatomaceous earth powder, 5% to 95% of stone N,
Even when changing the soil hardening agent O ~ 60%, granulated blast furnace slag O ~ 60%, powdered perlite O ~ 70%, and granular perlite O ~ 70%, the dew resistance, fire resistance, and heat insulation properties were improved. It was possible to form a wall surface that held.
実施例（４）
実施例（１）の耐火被覆材料１００部に対して、最大６
０部の砂を混入したときは、ざらに、その強度を増大せ
しめることができた。なあ、このときの砂の渚は、約４
０部程度のとき、最大強度となることがわかった。Example (4) Up to 6 parts per 100 parts of the fireproof coating material of Example (1)
When 0 parts of sand was mixed, the strength could be roughly increased. Hey, the sand beach at this time was about 4
It was found that the maximum strength was achieved when the amount was about 0 parts.
