건축물의 외벽 단열마감 시스템용 불연 단열재 보수보강 시공공법{Non-flammable insulation reinforcement construction method for exterior wall insulation finishing system of building}Non-flammable insulation reinforcement construction method for exterior wall insulation finishing system of building

본 발명은 건축물의 외벽 단열마감 시스템용 불연 단열재 보수보강 시공공법에 관한 것으로서, 더욱 상세하게는 기 시공된 외벽단열마감재 전체를 철거를 할 필요없이 화재발생시 확산을 차단할 수 있게 필로티 천장 끝 부분이나 창호 등의 개구부로 화염이 타고 올라 확산되는 일부분만을 철거하여 불연단열마감재로 보완하고 나머지부위는 철거가 필요없이 기 시공된 외벽단열마감재 외면에 적정두께의 불연단열마감재를 덧붙여 보수보강함으로써 기존 외벽단열마감재 전체를 철거할 필요없이 일부만을 철거하여 철거에 따른 비용과 시간을 현격히 축소시킴과 동시에 화재발생시 화재의 확산을 안정적으로 차단할 수 있으며, 베이스트랙과 메인트랙 등의 트랙구조체를 적용함으로써 기존 외벽단열마감재도 더욱 견고히 고정함과 동시에 덧붙여 시공되는 불연단열마감재의 고정도 안정적으로 견고하게 부착되도록 하여 기존 외벽단열마감재와 추가된 불연단열마감재에 대하여 벽체에 고정설치된 상태가 안정적으로 유지되어 지속적으로 내구성 및 단열성능을 유지할 수 있도록 하는 한편, 불연단열마감재의 외면에 순차적으로 메쉬접착, 마감재 처리 및 마감재 표면에 수용성 불소아크릴 투명코팅재를 도포하는 과정이 진행됨으로써 수용성 불소아크릴 투명코팅재에 의해 마감재 표면을 투명 코팅처리하여 방오염성을 더욱 향상시킬 수 있도록 한 건축물의 외벽 단열마감 시스템용 불연 단열재 보수보강 시공공법에 관한 것이다.The present invention relates to a non-combustible insulation repair and reinforcement construction method for an external wall insulation finishing system of a building, and more particularly, to block the spread in the event of a fire without the need to dismantle the entire exterior wall insulation finishing material already installed. Existing exterior wall insulation finishing material by removing only the part where the flame burns up and spreads through the opening of the back, and supplements it with non-combustible insulation finishing material. Existing exterior wall insulation and finishing materials by applying track structures such as the base track and the main track, are able to significantly reduce the cost and time required for demolition by removing only a part without the need to dismantle the whole, while at the same time stably blocking the spread of fire in the event of a fire. At the same time, the non-combustible insulation finishing material to be installed is also fixed more firmly and at the same time, the fixing of the additional non-combustible insulation finishing material is also stably and firmly attached. On the other hand, to maintain the performance, the process of sequentially attaching mesh to the outer surface of the non-combustible insulating finishing material, processing the finishing material, and applying the water-soluble fluoroacrylic transparent coating material to the surface of the finishing material is carried out, so that the surface of the finishing material is transparently coated with the water-soluble fluoroacrylic transparent coating material It relates to a construction method for repairing and reinforcing non-combustible insulation materials for the exterior wall insulation and finishing system of a building to further improve pollution resistance.

일반적으로 건축물의 외벽 단열마감 시스템은 철근 콘트리트나 조적벽면 구조체의 외벽에 스티로폼 단열재를 부착하여 그 표면에 시멘트계 접착제를 이용하여 유리섬유 메쉬가 함침되도록 도포하고 최종적으로, 아크릴 공중합성 수지로 조성된 플라스터를 이용하여 최종 마감하는 것이 현재 많이 사용되는 일반적인 시공방식이다.In general, the exterior wall insulation finishing system of a building attaches a Styrofoam insulation to the exterior wall of a reinforced concrete or masonry wall structure, applies a cement-based adhesive to the surface to be impregnated with a glass fiber mesh, and finally, a plaster composed of an acrylic copolymer resin Final finishing using a

즉, 일반적인 종래 외벽 단열마감 시스템의 시공은 도 1의 단면도에 도시된 바와 같이, 대략 가로 600mm, 세로 1200mm (두께는 설계에 따라 다양함)의 스티로폼 단열재(12)의 내표면에 아크릴수지계 에멀젼과 포틀랜드 시멘트를 1:1의 비율로 혼합한 시멘트계 접착제(15)를 지름이 100mm 정도 크기의 덩어리 즉, 떡밥 형태로 도 2의 예시도와 같이 소정 간격으로 여러 군데(6 내지 8개소)에 바른 후, 상기 건물 구조체(10)에 상하 좌우 레벨을 맞추면서 눌러 부착하고 양생한다.That is, as shown in the cross-sectional view of FIG. 1, the construction of a typical conventional exterior wall insulation finishing system is approximately 600 mm in width and 1200 mm in length (thickness varies according to design) on the inner surface of the styrofoam insulation 12 with an acrylic resin-based emulsion and After applying the cement-based adhesive 15, which is mixed with Portland cement in a ratio of 1:1, in a lump with a diameter of about 100 mm, that is, in the form of rice cakes, at predetermined intervals as shown in the exemplary diagram of FIG. 2 (6 to 8 places), It is attached and cured by pressing while aligning the vertical and horizontal levels to the building structure 10 .

이때, 건물 구조체(10) 면의 평활도 편차에 따라 상기 구조체(10)와 단열재(12) 사이에는 접착제(15)의 두께(대략10~30mm)만큼의 공간이 생기게 된다.At this time, a space corresponding to the thickness (approximately 10 to 30 mm) of the adhesive 15 is generated between the structure 10 and the heat insulating material 12 according to the deviation of the smoothness of the surface of the building structure 10 .

다음 공정으로, 단열재(12)의 외표면에 시멘트계 접착제(11)를 2mm 정도 두께로 전체적으로 평탄하게 도포한 후, 유리섬유재질로 이루어진 메쉬(13)를 함침시켜 양생하고, 양생과정으로 건조된 상기 메쉬(13)의 표면에 아크릴공중합성수지계의 엷은 벽 바름 마감재(14)를 최종적으로 도포하여 양생함으로써 건물 구조체(10)에 대한 외벽 단열마감 시스템으로서의 외벽 단열재 시공을 완료하게 된다.In the next process, the cement-based adhesive 11 is applied to the outer surface of the insulating material 12 to a thickness of about 2 mm, and then the mesh 13 made of the glass fiber material is impregnated and cured, and dried by the curing process. By finally applying and curing the thin wall coating finishing material 14 of the acrylic copolymer resin system on the surface of the mesh 13, the construction of the exterior wall insulation material as an exterior wall insulation finishing system for the building structure 10 is completed.

그러나 전술한 바와 같은 종래기술에 따른 외벽 단열마감 시스템의 시공에 있어서, 구조체(10)의 벽면 평활도 편차에 따라 단열재(12)와 외벽 면은 접착제(15)의 두께(대략10~30mm)만큼의 공간이 생기게 되는데, 이는 상기 단열재(12)가 별도의 고정기구 없이 떡밥 형태의 접착제(15)에 의하여 부착 및 양생되는 것을 의미하는 것으로, 점차 시간이 지나면서 접착력이 떨어져 상기 단열재(12)에 부착된 접착제(15)가 구조체(10)로부터 분리되는 문제점이 있었다.However, in the construction of the exterior wall insulation finishing system according to the prior art as described above, the insulation 12 and the exterior wall surface are the thickness of the adhesive 15 according to the deviation of the wall surface smoothness of the structure 10 (approximately 10 to 30 mm). A space is created, which means that the insulating material 12 is attached and cured by the adhesive 15 in the form of rice cake without a separate fixing mechanism. There was a problem in that the used adhesive 15 was separated from the structure 10 .

이러한 문제점을 상세하게 설명하면, 상기 외벽 단열마감 시스템은 시공 후 시간이 지나면서 풍압과 기온의 변화에 따른 수축팽창, 미숙성 단열재의 사용, 벽면의 이물질 등에 의한 접착불량 등으로 인하여 건물 구조체(10)에서 단열재(12)의 박리가 시작되며, 또한 풍압에 의해서 단열 마감된 벽면 전체가 반복적으로 움직여져서 보강유리섬유와 마감재 표면이 부분적으로 균열이 발생하게 된다.To explain this problem in detail, the exterior wall insulation finishing system is a building structure (10) due to shrinkage and expansion due to changes in wind pressure and temperature over time after construction, use of immature insulation, poor adhesion due to foreign substances on the wall, etc. ), the peeling of the insulating material 12 starts, and the entire wall surface that has been insulated and finished is repeatedly moved by wind pressure, so that the reinforcing glass fiber and the surface of the finishing material are partially cracked.

따라서, 도 3의 예시도와 같이 단열재(12)가 구조체(10)로부터 박리(17)되고 아울러 도 4a 및 도4b의 예시도에서와 같이 벽체에 균열(16)이 발생되면 균열 부위로의 누수로 인해 단열효과도 크게 낮아지는 것은 물론 외관도 지저분해 지며, 강풍 등에 의해, 도 5의 예시도와 같이 단열재의 탈락으로 이어지게 되어 인명과 재산상에 큰 피해를 줄 수 있다.Therefore, as in the exemplary view of FIG. 3 , when the insulating material 12 is peeled 17 from the structure 10 and a crack 16 is generated on the wall as in the exemplary views of FIGS. 4A and 4B, leakage to the cracked site Due to this, not only the insulation effect is greatly reduced, but also the appearance is messy, and due to strong winds, as shown in the exemplary diagram of FIG.

한편, 상기와 같은 단열재의 균열 또는 탈락 현상이 발생하게 되면 종래의 외벽 단열마감 시스템의 보수방법은 단열재가 외벽으로부터 탈락되는 것을 막기 위하여 도 6a의 예시도와 같은 두께 1mm, 지름 60mm 정도의 플라스틱 캡과, 굵기 8mm, 길이 110mm~160mm 정도의 플라스틱 화스너앙카를 이용하여, 도 6b의 예시도와 같이 건물 외벽에 단열재가 고정되도록 부분 취부를 하고, 그 표면을 아크릴공중합성수지계의 엷은 벽바름 마감재(14)로 부분 때움 마감을 하고, 균열 부분에는 실리콘이나 유성계열의 탄성피복제를 사용하여 일반도장을 하여 보수하였다.On the other hand, when the crack or drop-off phenomenon of the insulating material occurs as described above, the conventional repair method of the outer wall insulation finishing system includes a plastic cap having a thickness of 1 mm and a diameter of about 60 mm as shown in the exemplary view of FIG. , using a plastic fastener anchor with a thickness of 8 mm and a length of 110 mm to 160 mm, as shown in the exemplary diagram of FIG. 6b, partly mounts so that the insulating material is fixed to the outer wall of the building, and the surface is coated with an acrylic copolymer resin-based thin wall coating material (14) Partial filling was finished with a furnace, and the cracks were repaired by general painting using silicone or oil-based elastic coating materials.

이를 위한 종래기술로는 대한민국 특허등록 제10-1195345호(명칭 : 단열재 시공을 위한 벽체고정용 화스너) 및 대한민국 특허등록 제10-1575239호(명칭 : 건물 단열재 고정구조 및 그 시공방법)이 제시되어 있다.As a prior art for this purpose, Korean Patent Registration No. 10-1195345 (Name: Fastener for wall fixing for insulation construction) and Korean Patent Registration No. 10-1575239 (Name: Building insulation fixing structure and its construction method) are proposed. have.

한편, 상기와 같은 화스너앙카를 이용한 단열재 보수방법은 도 7a 및 도 7b의 예시도와 같이 단열 보수된 벽면의 화스너 앙카 시공자국과 시간이 얼마 지나지 않아서 화스너앙카 주변의 균열 및 보수된 단열재 균열부위의 재균열로 인해 또다시 누수 피해가 발생하게 되어 외관이 여전히 흉한 모습으로 노출되는 문제점이 있었다.On the other hand, the insulation repair method using the fastener anchor as described above, as shown in the exemplary drawings of FIGS. 7A and 7B , the fastener anchor construction marks on the insulation repaired wall surface and the cracks around the fastener anchor and the repaired insulation material cracks after a short period of time There was a problem that the appearance was still exposed as an ugly appearance due to the occurrence of leak damage again due to the crack.

아울러, 단열재 보수 시공 이후에도 화재에 취약하다는 문제가 있었다.In addition, there was a problem that the insulation was vulnerable to fire even after repair and construction.

더욱이, 기존 외벽단열마감 시스템을 준 불연 또는 불연의 시스템으로 보강하는 경우, 건축물의 화재확산 방지구조 기준에 따라 기존 단열재는 모두 철거한 후에 불연단열재인 미네럴울 단열재를 시공하였다.Furthermore, in the case of reinforcing the existing exterior wall insulation and finishing system with a semi-non-combustible or non-combustible system, in accordance with the fire spread prevention structure standards of the building, all existing insulation materials were removed and then mineral wool insulation, a non-combustible insulation material, was installed.

그러나 상기와 같은 불연의 시스템으로 보강하는 시공은 철거와 폐기물 처리의 문제로 비용이 과다하게 발생하는 문제가 있다.However, there is a problem in that the construction of reinforcing the non-combustible system as described above is excessively expensive due to the problems of demolition and waste disposal.

또한, 철거시 단열재 잔재물의 비산으로 잦은 민원이 발생하는 문제가 있다.In addition, there is a problem that frequent civil complaints occur due to the scattering of the insulation residues during demolition.

그리고 미네럴울보드 단열재가 기존 외벽단열마감 시스템의 비드법 단열재보다 단열성능이 떨어져 미네럴울보드 단열재의 두께가 두꺼워져야 하는 단점이 있다.In addition, the mineral wool board insulation material has a disadvantage in that the thickness of the mineral wool board insulation material needs to be increased because the insulation performance is inferior to that of the bead method insulation material of the existing exterior wall insulation finishing system.

그러므로 기 시공된 외벽단열마감 시스템으로서의 외벽단열마감재를 일부분만 철거하면서 기존 외벽단열마감재 외부에 추가로 불연단열마감재를 보수 시공함으로써 기존 외벽단열마감재 전체를 철거할 필요없이 일부만을 철거하여 철거에 따른 비용과 시간을 현격히 축소시킴과 동시에 화재발생시 화재의 확산을 안정적으로 차단할 수 있도록 하는 한편, 기존 외벽단열마감재와 추가된 불연단열마감재에 대하여 벽체에 고정설치된 상태가 안정적으로 유지되어 지속적으로 내구성 및 단열성능을 유지할 수 있도록 한 건축물의 외벽 단열마감 시스템용 불연 단열재 보수보강 시공공법에 대한 연구 및 개발이 요구되는 실정이다.Therefore, by removing only a part of the exterior wall insulation finishing material as an exterior wall insulation finishing system that has already been installed, and repairing and installing an additional non-combustible insulation finishing material on the outside of the existing exterior wall insulation finishing material, it is not necessary to dismantle the entire existing exterior wall insulation finishing material. It significantly reduces the amount of time and energy and at the same time makes it possible to stably block the spread of fire in case of fire. There is a need for research and development on repair and reinforcement construction methods for non-combustible insulation materials for exterior wall insulation and finishing systems of buildings to maintain the

상기와 같은 문제점을 해결하기 위하여, 본 발명은 기 시공된 외벽단열마감재 전체를 철거를 할 필요없이 화재발생시 확산을 차단할 수 있게 필로티 천장 끝 부분이나 창호 등의 개구부로 화염이 타고 올라 확산되는 일부분만을 철거하여 불연단열마감재로 보완하고 나머지부위는 철거가 필요없이 기 시공된 외벽단열마감재 외면에 적정두께의 불연단열마감재를 덧붙여 보수보강함으로써 기존 외벽단열마감재 전체를 철거할 필요없이 일부만을 철거하여 철거에 따른 비용과 시간을 현격히 축소시킴과 동시에 화재발생시 화재의 확산을 안정적으로 차단할 수 있도록 한 건축물의 외벽 단열마감 시스템용 불연 단열재 보수보강 시공공법을 제공하는 것을 목적으로 한다.In order to solve the above problems, the present invention provides only the part where the flame burns up and spreads through the openings such as the tip of the piloti ceiling or windows to block the spread in case of fire without the need to dismantle the entire pre-constructed exterior wall insulation finishing material. It is removed and supplemented with non-combustible insulation finishing materials, and the rest of the parts are removed without the need to dismantle the existing exterior wall insulation finishing materials by adding non-combustible insulation finishing materials of an appropriate thickness to the outer surface of the already installed exterior wall insulation finishing materials for repair and reinforcement. The purpose of the present invention is to provide a non-combustible insulation repair and reinforcement construction method for the exterior wall insulation finishing system of a building that can significantly reduce the cost and time required and at the same time reliably block the spread of fire in the event of a fire.

본 발명에 따른 기술의 다른 목적은 베이스트랙과 메인트랙 등의 트랙구조체를 적용함으로써 기존 외벽단열마감재도 더욱 견고히 고정함과 동시에 덧붙여 시공되는 불연단열마감재의 고정도 안정적으로 견고하게 부착되도록 하여 기존 외벽단열마감재와 추가된 불연단열마감재에 대하여 벽체에 고정설치된 상태가 안정적으로 유지되어 지속적으로 내구성 및 단열성능을 유지할 수 있도록 함에 있다.Another object of the technology according to the present invention is to apply a track structure such as a base track and a main track to more firmly fix the existing exterior wall insulation finish material, and at the same time to ensure that the non-combustible insulation finish material to be installed is also stably and firmly attached to the existing exterior wall With respect to the insulating finishing material and the added non-combustible insulating finishing material, the fixed installation state on the wall is stably maintained so that durability and thermal insulation performance can be maintained continuously.
