Description

단열효과를 강화시킨 건축물의 단열방수공법Insulation waterproofing method of building with enhanced insulation effect
본 발명은 건축물의 단열효과를 증대시키기 위한 방수공법에 관한 것으로, 상세하게는 인장강도 및 파단강도를 향상시킨 단열효과를 가진 팽창 퍼라이트 조성물을 이용한 건축물의 단열방수공법에 관한 것이다.The present invention relates to a waterproof method for increasing the thermal insulation effect of the building, and more particularly to a thermal insulation waterproof method of the building using the expanded perlite composition having an insulation effect to improve the tensile strength and the breaking strength.
각종 건축물의 누수방지를 위한 방수공사는 특히 콘크리트 건축 구조물의 유지 및 보수를 위해서는 필수적인 산업분야이다. Waterproofing work to prevent leakage of various buildings is an essential industrial field especially for the maintenance and repair of concrete building structures.
일반적으로 건물 옥상이나 주차장의 상부 등에는 누수를 방지하기 위해 방수공사를 하는데, 시공상 편의로 일정 규격의 방수시트 위에 단열재(예를 들어, 스치로폼)를 이용하는 공사가 널리 채택되고 있다. 그러나, 방수시트는 온도변화에 민감하기 때문에 수축과 팽창이 잘 발생하고 이에 따라 방수성능이 저하될 뿐만 아니라 물의 침투로 인해 단열효과도 현저히 감소시키고 있다. In general, waterproof construction is performed on the roof of a building or an upper part of a parking lot to prevent leakage. For construction convenience, construction using a heat insulating material (eg, styrofoam) on a waterproof sheet of a standard is widely adopted. However, since the waterproof sheet is sensitive to temperature change, shrinkage and expansion occur well, and accordingly, the waterproofing performance is deteriorated and the thermal insulation effect is significantly reduced due to the penetration of water.
뿐만 아니라, 방수시트는 규격화된 크기로 인해서 시트 간에 이음부가 발생할 수 있으며, 이러한 이음부로 인해 방수성능이 크게 저하되고 하자의 원인이 되고 있다.  In addition, the waterproof sheet may be a joint between the sheets due to the standardized size, due to such a joint is greatly reduced the waterproof performance and causes the defect.
한편으로는, 건축물의 단열공사를 위해서는 상기한 방수공사와 별개로 시공하거나, 방수효과를 가진 시트를 별개로 이용하고 있기 때문에 상기한 바와 같은 종래의 문제점을 피할 수가 없었다. On the other hand, for the thermal insulation work of buildings, the conventional problems as described above could not be avoided because the construction is performed separately from the above-described waterproofing work or the sheet having the waterproofing effect is used separately.
또한, 종래의 단열 및 방수공사는 여러 공정을 거치는 단계로 구성되는바, 예를 들어, 콘크리트 구조물 위에 시트 방수공사를 하고 그 위에 단열재(예로서, 스치로폼)를 설치하며 그 위에 다시 와이어 매쉬 및 누름몰탈 공사를 수행하는 것이 일반적인 공법이다. 따라서, 공정이 복잡하고 단가가 비싼 단점이 있을 뿐만 아니라 사용되는 단열재에 따라서 화재시에 유독가스가 발생함으로써 심각한 문제점이 있다. In addition, the conventional heat insulation and waterproof construction is composed of a step through a number of processes, for example, to waterproof the sheet on a concrete structure, and to install a heat insulator (for example, styrofoam) on the wire mesh and press again on it It is common practice to carry out mortar construction. Therefore, there is a serious problem in that toxic gas is generated at the time of fire depending on the heat insulating material used as well as the complicated process and the expensive price.
현재, 단열효과의 증대를 위해서 퍼라이트를 이용한 공법이 연구되고 있다. At present, a method using perlite has been studied to increase the insulation effect.
퍼라이트는 급격한 열에 의하여 희고 기공이 많은 경량의 물질 형태로 팽창될 수 있는 휘발 성분을 함유하고 있는 비정질 암석이다. 상기 퍼라이트를 미세하게 분쇄하여 1000℃ 이상의 고열을 급격히 가하면, 상기 퍼라이트에 함유된 휘발 성분이 가스화되어 연화된 입자의 내부에서 팽창하면서 가스가 빠져나가 내부에 기공이 형성된다. 이때, 상기 퍼라이트 본래 부피보다 대략 10 내지 20배 팽창된 팽창 퍼라이트가 형성된다. Perlite is an amorphous rock that contains volatile components that can be expanded to a white, porous, lightweight material form by rapid heat. When the ferrite is finely pulverized and a high heat of 1000 ° C. or more is rapidly applied, the volatile components contained in the perlite gasify and expand in the softened particles, thereby allowing gas to escape and forming pores therein. In this case, expanded perlite is formed which is expanded approximately 10 to 20 times the original volume of the perlite.
상기 팽창 퍼라이트는 기밀한 소기포가 유리질 피막에 둘러싸인 형상을 갖기 때문에 가볍고, 중성의 무기물 재질로써 독성이 없고 불연성을 가지며, 많은 기공으로 인하여 단열성 및 흡음성이 뛰어난 장점이 있다. 최근 이러한 팽창 퍼라이트의 장점들을 활용하여 다양한 산업 분야에 이용되고 있다. 특히, 팽창 퍼라이트는 The expanded perlite is light because the airtight small air bubbles have a shape surrounded by a glassy film, and is non-toxic and non-flammable as a neutral inorganic material, and has excellent heat insulation and sound absorption due to many pores. Recently, by utilizing the advantages of the expanded perlite has been used in a variety of industries. In particular, the expansion perlite
천장재, 인테리어재, 칸막이재 및 단열재 등의 건축용 자재, 극장, 공연장, 체육관 등의 음향 시설, 도로, 철도 및 터널 등의 방음벽, 토양 개량 및 인공 토양 등의 농업 분야 등에 사용된다.It is used for building materials such as ceiling materials, interior materials, partition materials and insulation materials, acoustic facilities such as theaters, performance halls, gymnasiums, soundproof walls such as roads, railways and tunnels, soil improvement, and agricultural fields such as artificial soils.
그러나 상기 건축용 자재에 상기 팽창 퍼라이트가 사용되는 경우, 친환경 요소 및 경량성 등은 크게 개선되지만, 상기 팽창 퍼라이트 자체의 기공성에 의하여 구조물의 강도가 떨어지는 결함이 있고, 흡수성으로 인해 외장재로는 사용할 수 없는 단점이 있다. However, when the expanded perlite is used in the building material, the environmentally friendly elements and light weight are greatly improved, but the strength of the structure is lowered due to the porosity of the expanded perlite itself, and the absorbent cannot be used as an exterior material. There are disadvantages.
본 발명은 상기와 같은 종래의 문제점을 해결코자 하는 것으로, 건축물의 옥상이나 큰 하중을 받는 바닥 등에 단열효과가 큰 퍼라이트 조성물을 사용하여 단열 및 방수공사를 일괄처리할 수 있도록 한 것이다.The present invention is to solve the above conventional problems, it is to enable a batch treatment of the heat insulation and waterproof construction using a perlite composition having a large heat insulation effect, such as the roof of the building or the floor under heavy load.
특히, 본 발명에 사용되는 퍼라이트는 친환경적 재료로서 단열성, 불연성, 및 흡음성이 탁월하기 때문에 건축자재로서 유용하게 사용할 수 있도록 하는 것이 본 발명의 또 다른 목적이다.Particularly, it is another object of the present invention to make the perlite used in the present invention be useful as a building material because it is excellent in heat insulation, non-combustibility, and sound absorption as an environmentally friendly material.
또한 본 발명에 따른 단열방수공법은 종래의 단열 및 방수 공사를 대체하여 일괄처리할 수 있도록 하고 뿐만 아니라 종래의 화재시에 발생하는 유독가스를 방지하는 것이 본 발명의 또 다른 목적이다.In addition, the thermal insulation waterproof method according to the present invention is to replace the conventional thermal insulation and waterproof construction, and also to prevent the toxic gas generated in the conventional fire as well as another object of the present invention.
상기한 목적을 달성하기 위해 본 발명에 의한 방수공법은 다음의 수단으로 구성된다: In order to achieve the above object, the waterproofing method according to the present invention comprises the following means:

본 발명에 따른 방수공법에 의해서 시공된 건축물은 우수한 단열효과, 불연성 및 흡음성을 가지고 있을 뿐만 아니라 친환경적 소재로서 건축물의 외장 및 바닥 공사에 유용하게 사용할 수 있는 강도를 나타낸다.The building constructed by the waterproofing method according to the present invention not only has excellent heat insulation effect, nonflammability and sound absorption, but also shows strength that can be usefully used for exterior and floor construction of buildings as an environmentally friendly material.
뿐만 아니라, 단열 및 방수공사를 일괄처리함으로써 공정이 간단하고 비용이 저렴하며, 화재시에 유독가스를 발생시키지 않는 장점이 있다.In addition, by batch processing the heat insulation and waterproof construction, the process is simple, low cost, there is an advantage that does not generate toxic gas in case of fire.
특히, 가건축물에 주로 사용하는 샌드위치 판넬을 본 발명에 따른 단열방수공법을 사용할 경우에는 탁월한 단열효과를 얻을 수 있을 뿐만 아니라 화재시 발생하는 유독가스로부터의 피해를 줄일 수가 있다.In particular, when the sandwich panel mainly used for temporary buildings using the adiabatic waterproofing method according to the present invention can not only obtain an excellent thermal insulation effect, but also reduce the damage from toxic gases generated in a fire.
