Description

Flame spreading prevention function finishing material manufacturing and construction method {MANUFACTURING AND CONSTRUCTION OF FINISHING MATERIAL FOR FLAME DIFFUSION PREVECTION CAPABILITY}

The present invention relates to a method of manufacturing and constructing a finishing material for preventing flame spreading, and more particularly, a flame in which a capsule-type extinguishing agent is mixed with primers, mortars, and finishing materials for exterior wall insulation or interior and exterior of various buildings with a semi-non-combustible function. It relates to the manufacturing and construction method of the diffusion preventing function finishing material.

Various materials used in new houses emit a large amount of volatile organic compounds including carcinogens such as benzene, toluene, chloroform, acetone, styrene, and formaldehyde.

These organic compounds irritate the eyes, nose, throat, etc., causing various health disorders such as headache, cough, itchiness or atopic dermatitis, dizziness, fatigue, and decreased concentration. In the case of prolonged exposure, breathing such as asthma It has been found that even fatal diseases such as airborne diseases, heart disease, and cancer can be caused.

Therefore, the interior surfaces of buildings such as walls, ceilings, and floors can be finished with eco-friendly natural materials such as loess, charcoal, marble, and natural wood that radiate a large amount of far-infrared rays, or purify the air with antibacterial and deodorizing effects. Various construction methods have been developed to prevent sick house syndrome, such as coating the interior surface of a building with a photocatalyst, and are being constructed in new buildings.

However, the conventional construction methods used for the prevention of sick house syndrome use natural materials as a finishing material, so the cost of materials is generally high and construction is difficult.Therefore, it is a problem that a considerable increase in construction cost and extension of the construction period are required. In the event of a fire, if flames are continuously supplied from other inflammable substances, the self-extinguishing function is limited and the fire is bound to spread.

More specifically, the outer support 393 and the inner support 392 are movable to the lower end of the pillar portion 151 along the longitudinal direction of the pillar portion 151, but a second fixing portion connected to be fixed to the upper end ( 395), you can only move up to a certain length or more.

The outer support 393 and the inner support 392 may be fixed with the second fixing part 395, but may be implemented in a configuration that rotates as the central column part 316 rotates, or a configuration that does not rotate. It could be.

The connector 391 may be formed in a form that surrounds the outside of the inner support 392 and is movable to the lowermost end of the column part 151, and when a foreign substance gets stuck in contact with the lower end of the column part 151, It may be formed in a form that can be separated from the inner support 392 for cleaning.

The above-described embodiments are for illustrative purposes only, and those of ordinary skill in the art to which the above-described embodiments belong can easily transform into other specific forms without changing the technical idea or essential features of the above-described embodiments. You can understand. Therefore, it should be understood that the above-described embodiments are illustrative and non-limiting in all respects. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as being distributed may also be implemented in a combined form.

The scope to be protected through the present specification is indicated by the claims to be described later rather than the detailed description, and should be interpreted as including all changes or modified forms derived from the meaning and scope of the claims and the concept of equivalents thereof. .
