본 발명은 단열 몰탈에 관한 것으로서, 특히 폐유리를 재활용한 재료를 원료로 하는 경량 골재를 이용한 단열 몰탈에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat insulating mortar, and more particularly, to a heat insulating mortar using a lightweight aggregate made of a material recycled from waste glass as a raw material.
일반적으로 건물 또는 건축물의 외면은 콘크리트, 타일, 철, 벽돌, 석재, 목재 등과 같은 재료를 이용하여 마감 처리되고 있다. 그리고, 대표적인 외관 마감방식으로 EPS 보드를 사용하는 일명 드라이비트 공법이 널리 실시되고 있다. 이와 같이 EPS 보드나 단열 패널을 사용한 외단열 공법으로는 특허등록 제1035973호에 공지되어 있다. Generally, the outer surface of a building or building is finished using materials such as concrete, tile, iron, brick, stone, wood and the like. In addition, a dry bit process using an EPS board as a typical appearance finishing method is widely carried out. As described above, an external heat insulating method using an EPS board or an insulating panel is known from Patent Registration No. 1035973.
특허등록 제1035973호의 외단열 패널 유닛 및 이를 이용한 외단열 시스템에 의하면, 건물의 외벽에 단열을 위해 설치되는 것으로 단열재로 성형제작되며 소정의 두께를 가진 판재를 세운 형상의 제1패널; 상기 제1패널과 두께를 제외하고 같은 규격으로 성형제작되어 상기 제1패널의 전면의 사선 아래에 부착되는 제2패널; 상기 제2패널의 상부에 부착되는 제3패널; 및 판재를 절단 절곡하여 제작되어 절곡된 부위가 패널상단 고정부, 패널하단 고정부, 외벽 상부접촉부 및 외벽 하부접촉부로 나뉘고 상기 외벽 상부접촉부에는 앵커구멍이 형성되어 건물의 외벽에 상기 앵커구멍을 통하여 앵커가 결합되어 고정되는 것으로, 상기 제1패널, 제2패널 및 제3패널의 패널 결합체에 상기 패널상단 고정부 및 패널하단 고정부가 상기 제1패널과 제2패널의 접촉부에 파고들어 상기 패널 결합체를 건물의 외벽에 부착시키기 위한 다수 개의 패스너로 구성되며: 인접하는 상기 패널 결합체와 상하좌우 맞물리게 결합되고, 상기 제1패널, 제2패널 및 제3패널은 방형으로 제작되고, 상기 제2패널은 상기 제1패널의 상단 및 한쪽 측단으로부터 15~50mm 이동하여 상기 제1패널의 전면의 사선 아래에 부착되며, 상기 제3패널은 상기 제2패널의 상단 및 한쪽 측단으로부터 5~50mm 이동하여 상기 제2패널의 전면의 사선 아래에 부착되되 상기 제3패널의 하단 및 측단은 상기 제2패널의 하단 및 다른 쪽 측단과 일치하고, 상기 패널상단 고정부 및 패널하단 고정부가 삽입될 수 있도록 상기 제1패널과 제2패널의 접촉부에 다수 개의 패스너 고정홈이 형성되는 것을 특징으로 하고 있다. According to the external heat insulating panel unit of Patent Registration No. 1035973 and the external heat insulating system using the same, a first panel formed as a heat insulating material on the external wall of the building and having a predetermined thickness is formed. A second panel formed to have the same size as the first panel except for the thickness, and attached to a lower portion of the front surface of the first panel; A third panel attached to an upper portion of the second panel; And a folded portion is divided into a panel top fixing portion, a panel bottom fixing portion, an outer wall upper contact portion, and an outer wall lower contact portion, and an anchor hole is formed in the contact portion of the outer wall, The panel top fixing part and the panel lower end fixing part of the first panel, the second panel and the third panel are fixed to the contact parts of the first panel and the second panel, Wherein the first panel, the second panel, and the third panel are formed in a square shape, and the second panel is formed by a plurality of fasteners for attaching the first panel, the second panel and the third panel to the outer wall of the building, The first panel is moved 15 to 50 mm from the upper end and one end of the first panel and attached to the lower surface of the first panel under the oblique line, And the lower panel and the side panel of the third panel coincide with the lower panel and the other panel of the second panel, And a plurality of fastener fixing grooves are formed at the contact portions of the first panel and the second panel so that the panel lower end fixing portion can be inserted.
이와 같은 구성에 의해, 단열패널 제작에 있어서 기존에 사용되던 섬유몰탈, 유리섬유메쉬 등의 레이어(layer)를 생략하고, 단열층과 마감층을 가장 단순화된 레이어로 일체로 공장 제작하여 경제적이고, 단열패널 상호간의 결합형상을 개선하여 서로 단단히 맞물려 열기나 냉기가 빠져나가지 않아 에너지 손실이 적으며, 종래의 단열패널에 사용되지 않던 폴리우레탄 코팅을 도입하여 내구성이 좋고 표면에 다양한 마감이 가능하고, 규격화된 부재를 가지고 건식시공되므로 미숙련공도 소정의 품질로 시공할 수 있고 유지보수가 간편한 효과를 제공한다. With this construction, it is possible to manufacture a heat insulating panel by omitting a layer such as a fiber mortar and a glass fiber mesh which have been used in the prior art, and to integrally manufacture a heat insulating layer and a finish layer as a simplest layer, It improves the interconnection between the panels and tightly interlocks with each other, so that it does not escape heat or cold air, and energy loss is small. By introducing a polyurethane coating which was not used in the conventional heat insulating panel, it is possible to have various durability, And thus, it is possible to construct a sophisticated worker with a predetermined quality and to provide an easy maintenance effect.
그러나, 상기 단열 유닛은 건물 외벽 전체에 이음부분이 발생하여 단열 효과가 저하됨은 물론 크랙이나 탈락의 원인이 되어 심각한 하자를 초래하는 문제점이 있다. However, in the above-mentioned heat insulating unit, a joint part is formed on the entire outer wall of the building, thereby deteriorating the adiabatic effect and causing cracks or detachment, which causes serious defects.
한편, 다른 하나의 공지된 특허로서 ‘우수한 크랙 저항성과 고탄성을 갖는 외단열용 몰탈’을 발명의 명칭으로 하는 특허등록 제1016265호에 의하면, 시멘트 30~35중량%; 알루미나 시멘트 2~4중량%; 무수석고 0.5~1.2중량%; 규사 40~50중량%; 탄산칼슘 12~15중량%; 재유화형 분말수지 3~5중량%; 소포제 0.03~0.08중량%; 메틸셀룰로우즈 0.1~0.2중량%; 화이버 1~2중량%; 및 분말방수제 0.2~0.5중량%;로 이루어지며: 상기 시멘트는 포틀랜드 시멘트이며 목표압축강도가 4주 양생 기준으로 120~140㎏/cm 가 되도록 함유하게 되고, 상기 규사는 시공 후 그 표면이 너무 거칠지 않고 매끈해지도록 0.1~0.4㎜ 의 크기로 하고, 상기 탄산칼슘의 크기는 90~110메시(mesh)로 되게 하고, 상기 재유화형 분말수지는 기계적 성능이 우수한 아크릴계와 접착강도가 우수한 EVA(Ethylene Vinyl Acetate)수지가 이용되고, 상기 화이버는 수축에 의한 크랙저항성을 높이기 위해서 나일론계, 아크릴계 및 폴리프로필렌계 중 어느 한 가지 이상이 혼합되어 사용되고, 길이는 0.05~3㎜ 범위이며, 상기 분말방수제는 방수성능이 우수한 실리콘계의 제품이 이용되는 것을 특징으로 하고 있다.Meanwhile, according to another patent of Japanese Patent No. 10,162,665 entitled " Mortar for external heat insulation having excellent crack resistance and high elasticity ", 30 to 35% by weight of cement; 2 to 4% by weight of alumina cement; 0.5 to 1.2% by weight of anhydrous gypsum; 40 to 50% by weight of silica sand; 12 to 15% by weight of calcium carbonate; 3 to 5% by weight of re-emulsified powder resin; 0.03 to 0.08% by weight of defoamer; 0.1 to 0.2% by weight of methylcellulose; 1 to 2 wt% of fibers; And 0.2 to 0.5% by weight of a powder waterproofing agent; the cement is a Portland cement and contains a target compressive strength of 120 to 140 kg / cm on a four-week curing basis, and the surface of the silica sand is too rough And the size of the calcium carbonate is made 90 to 110 mesh. The re-melting type powder resin is made of an acrylic resin having excellent mechanical performance and an EVA (Ethylene Vinyl Acetate resin is used. The fiber is mixed with at least one of nylon, acryl and polypropylene to increase the crack resistance due to shrinkage, the length is in the range of 0.05 to 3 mm, and the powder waterproofing agent is waterproof And a silicon-based product having excellent performance is used.
이 같은 구성적 특징에 의해, 시멘트의 함량을 조절함으로써 최소한의 재유화형 분말수지의 첨가로도 고탄성을 가질 수 있게 하고, 방수제의 첨가로 내수성이 좋아 장마철의 우수에도 탈락이나 크랙의 문제가 발생되지 않게 하며, 화이버를 첨가함으로써 수축에 의한 크랙 또한 저감이 가능하여 기존 건물뿐만 아니라 초고층 건물의 외단열 시공에 있어서도 크랙이나 탈락 현상이 전혀 발생되지 않게 하는 효과를 제공하게 되는 것이다. With such a constitutional characteristic, by adjusting the content of cement, it is possible to have high elasticity even with the addition of the minimum re-oiling type resin, and it is good in water resistance due to addition of waterproofing agent, And cracks due to shrinkage can be reduced by adding a fiber, so that it is possible to prevent the occurrence of a crack or a dropout phenomenon at the time of outer insulation construction of an existing building as well as a super high-rise building.
그러나, 이와 같은 외단열용 몰탈 또한 내화성이 상대적으로 취약하고, 내충격성이 취약함은 물론, 특히 건물의 외벽을 형성하는 콘크리트와의 접착불량으로 인한 탈락 현상에 의해 하자를 초래하는 문제점이 있다.
However, such a mortar for external heat insulation also has a problem in that the fire resistance is relatively weak, the impact resistance is poor, and, in particular, the deterioration due to the adhesion failure with concrete forming the outer wall of the building causes defects.
이에 본 발명은 상기 문제점들을 해결하기 위해 발명된 것으로서, 본 발명의 목적은 이음부가 없고, 단열성이 우수하며, 강도 및 접착력이 우수하여 박리 및 탈락을 방지하여, 내화성능이 향상되고, 단열성이 향상되며, 크랙발생을 방지하고, 내충격성이 향상된 단열 몰탈을 제공하는데 있다.
