施工が容易である等の利点をもち広（実施されている。[Prior Art] Conventionally, spraying of upwardly shaped monolithic refractories has been used in construction sites where pouring or stamping is difficult. Spraying is a construction method that does not require a construction frame, thereby reducing costs, high work efficiency, and easy hot construction, and is widely used.

770, JP-A-51-109008, and JP-A-51-58723, which use ultrafine powder and dispersants, require a large amount of water during construction. Because of this, the refractory construction body obtained by spraying has a large porosity (low density) and poor strength.

っていない。Spraying is a method of reducing the amount of water in the construction method, and JP-A-58-24785 proposes a dry spraying method in which spraying is performed by adding a surfactant to the material. However, even this method requires a construction moisture content of 10% or more, and has not yet achieved a significant quality improvement.

-109008 and Japanese Patent Application Laid-Open No. 51-58723, a method of applying ultrafine powder and dispersant for high-density pouring materials to sprayed materials was considered, but dry spraying is not suitable for the above-mentioned interface. Similar to methods using activators, spraying requires a very short time to mix and knead the construction water added with a nozzle with the spraying material, so a sufficient water reduction effect cannot be obtained; We cannot expect widespread quality improvement.

干の改善しが期待できない。On the other hand, when spraying materials containing ultrafine powder and dispersants are applied using the wet spraying method, the spraying materials are mixed with water molecules that contain the entire amount of water in the construction, so the effect of the dispersant is less effective. However, when the water content is equivalent to that of high-density pouring material, the high viscosity of the mixed spraying material makes it difficult to pump the material with a hose, and construction cannot be performed by spraying. Since it is necessary to increase the amount of water applied during construction compared to high-density pouring material, spraying cannot be expected to improve the quality of the constructed body even slightly.

In the step, 175 to 3/4 of the water content of the construction water and the fireproofing composition are kneaded in advance in a mixer, and the mixture is fed under pressure to a dry spray gun, and the kneaded fireproof composition is mixed with the remaining water of the construction water content and the fireproof composition. The object of the present invention is to provide a method for spraying a fire-resistant composition, characterized in that a solution of a curing accelerator is added by a dry spraying gun or nozzle.

It is preferable that the addition amount of the refractory ultra-fine powder is 5 to 30% by weight, and if the addition amount of the refractory ultra-fine powder exceeds 30% by weight, it is difficult to achieve high density, so it is not preferable, and it is less than 5% by weight. It is difficult to achieve high density, and spraying is not preferable because appropriate viscosity may not be obtained. ! The above can be used in combination.

By adding ~3/4 water and pre-kneading with a mixer, the ultra-fine powder and hydraulic alumina cement become partially dispersed, and can be completely mixed even in a short time when adding the remainder of the construction water with a nozzle, even with cross-contact. A dispersion effect is obtained, and spraying with a low moisture content becomes possible.

One or more dispersants selected from the group consisting of 0.
In a spraying construction method in which a fireproof composition containing 01 to 0.5% by weight and a hardening accelerator are sprayed, the fireproof composition is mixed with water in an amount of 1/5 to 3/4 of the amount of water to be applied. The composition is kneaded in advance with a mixer and then force-fed to a dry spray gun, and a solution consisting of water in an amount remaining in the amount of water to be applied and a curing accelerator is added to the kneaded fireproof composition using the spray nozzle of the dry spray gun. Characteristic method of spraying fire-resistant compositions.
