Description
본 발명은 적벽돌 조적벽체면이나 타일 벽면과 같이 균일하지 않은 벽면 또는 또는 균열이 심한 일반 모르타르 마감 벽면에 프라이머 도포하거나 벽면을 균일하게 가는 공정 없이 분쇄된 발포 폴리스티렌을 포함한 모르타르를 벽면에 발라줌으로써 간단히 단열층을 형성할 수 있는 건물 외벽의 단열방수 보수보강 시공방법에 관한 것이다.The present invention provides a simple insulating layer by applying a mortar including crushed expanded polystyrene to a wall without applying a primer to a non-uniform wall surface, such as a red brick masonry wall or a tile wall, or a general mortar-finished wall with high cracks or evenly grinding the wall. It relates to a thermal insulation waterproof repair reinforcement construction method of the building outer wall that can form a.
그리고 단열효과가 뛰어나면서도 방수, 방오 효과 또한 뛰어나며 광택도 우수한 건물 외벽의 단열방수 보수보강 시공방법에 관한 것이다.The present invention also relates to a method of waterproofing and reinforcing the construction of an exterior wall of a building, which has excellent heat insulation effect, waterproof, antifouling effect, and excellent gloss.
일반적으로 건축된지 5년에서 10년 정도 지난 저층의 노후화된 건물들은 주로 벽돌을 쌓아 건물이 지지되도록 하고, 내부 쪽으로 내단열을 선택적으로 한 다음 내부 미장이나 내장재로 마감을 하고, 외부 쪽으로도 외단열을 선택적으로 한 다음 외장재로 외부 마감을 하였다. 여기서 사용되는 외장재로는 대표적으로 조적벽돌, 타일 등이 있을 수 있는데, 이러한 조적벽돌이나 타일은 모르타르를 접착제로 사용하여 벽에 붙이거나 쌓아올리며 각 사이는 코킹재로 메우는 형태로 외부 마감을 하였다. Low-rise, aging buildings, typically 5 to 10 years old, are usually built of bricks to support the building, optionally with internal insulation on the inside, then finished with internal plaster or interior materials, and externally on the outside. Was optionally followed by an exterior finish of exterior material. The exterior materials used here may be masonry bricks, tiles, etc., such masonry bricks or tiles are mortar is used as an adhesive to the wall or piled up, and each has an exterior finish in the form of filling with a caulking material.
그런데 이러한 노후화된 건물들은 대부분 건축 당시 외부 단열에 크게 신경을 쓰지 않은 관계로 외부단열방수에 취약한 문제점이 있고 외부 단열방수을 하였다 하더라도 노후화되어 단열효과가 크게 떨어진 상태라 고유가 시대에 냉, 난방비를 증가시키고 있다. 그리고 조적벽돌이나 타일이 외부로 드러나게 마감을 하는 경우 시간이 지남에 따라 모르타르와 코킹재가 수축하여 줄눈부에 크랙 및 탈락을 발생시키고 있으며 이는 건물의 균열을 발생시켜 건물의 외부 단열방수 효과를 더욱 떨어지게 하며 내부에 결로가 생기거나 곰팡이가 번식하게 하는 요인으로 작용한다.However, most of these aging buildings have a problem that they are vulnerable to external insulation waterproofing because they do not pay much attention to external insulation at the time of construction, and even if the external insulation waterproofing is aging, the insulation effect is greatly reduced. have. In addition, when the masonry brick or tile is finished to the outside, mortar and caulking material contracts over time, causing cracks and dropouts at the joints, which causes cracks in the building, which in turn lowers the effect of waterproofing the building's exterior insulation. It causes condensation or mold to grow inside.
이에 이러한 노후화된 건물을 재건축 또는 외벽을 보수, 보강하거나 리모델링을 하였는데 재건축은 건축비의 부담과 주차장 및 인도 및 도로의 확보와 관련한 법 등으로 쉽지 않아 리모델링을 하거나 외벽만을 보수, 보강하는 추세에 있다.As such, the aging buildings have been reconstructed or repaired, reinforced or remodeled. However, the reconstruction is not easy due to the burden of construction costs and the laws related to securing parking lots, sidewalks and roads.
이러한 건물의 리모델링 또는 외벽의 보수, 보강 방법으로는 벽돌 또는 타일로 이루어진 벽체 표면에 접착제를 도포한 후 발포 폴리스티렌 단열재를 부착하고 상기 단열판재 위에 시멘트 페이스트를 도포하거나 외부 마감패널을 부착하는 방법과 같은 일반적인 방법이 있다. The remodeling of the building or repairing or reinforcing the outer wall may be performed by applying an adhesive to the surface of the wall made of brick or tile, then attaching a foam polystyrene insulation and applying cement paste on the insulation board or attaching an external finishing panel. There is a general way.
이러한 방법 이외에는 드라이비트 보수, 보강 방법으로 조적벽돌 바탕 면을 그라인더 등을 이용하여 균일하게 샌딩 한 다음 상기 바탕 면에 드라이비트 단열판을 부착하고 마감재를 이용하여 마감하는 방식이 있다.In addition to these methods, there is a method of uniformly sanding the masonry brick base surface using a grinder or the like by using dry bit repair and reinforcement methods, and then attaching a dry bit insulating plate to the base surface and finishing using a finish.
그러나 이러한 방법들 중 일반적인 방법은 조적벽돌 벽면이나 타일 벽면이 균일하지 않거나 미끄럽고, 각각의 사이 사이에는 줄눈부가 있어 직사각형 형태의 균일한 단열재를 벽면에 평탄하고 균일하게 부착하기 힘들며 시일이 지나면 벽면과 단열재가 분리될 염려가 있다. However, the common method among these methods is that the masonry brick or tile wall is not uniform or slippery, and there is a joint between each one, making it difficult to attach a rectangular uniform insulation to the wall flatly and uniformly. There is a risk of separation.
이에 외부 벽면에 프라이머를 먼저 도포하여 균일하게 한 다음 단열재를 부착할 수도 있지만 이러할 경우 공정이 복잡해지고 비용이 상승할 수 있다.The primer may be applied to the outer wall first to make it uniform, and then the insulation may be attached. However, this may complicate the process and increase the cost.
마찬가지로 드라이비트 보수, 보강 방법도 먼저 벽면을 균일하게 갈아주어야 하며 작업대를 따로 설치해야하는 번거로움이 생길 수 있다.Likewise, dry bit repair and reinforcement methods may require a uniform grinding of the walls and a separate workbench.
그리고 이러한 보수, 보강 방법은 단열효과에 비해 방수, 방오 성능이 저하될 염려가 있다. 이에 우레탄 수지, 황토 등을 이용하여 보수, 보강할 수 있지만 이 경우에는 보수, 보강 비용이 급격하게 상승한다는 문제점을 야기할 수 있다.In addition, such repair and reinforcement methods may have a deterioration in water resistance and antifouling performance as compared with the insulation effect. The urethane resin, loess, etc. can be used to repair and reinforce, but in this case, the cost of repair and reinforcement may increase rapidly.
본 발명은 상기와 같은 문제점을 해결하기 위하여 적벽돌 조적벽체면이나 타일 벽면과 같이 균일하지 않은 벽면 또는 균열이 심한 일반 모르타르 마감 벽면에 프라이머 도포하거나 벽면을 균일하게 가는 공정 없이 분쇄된 폐 발포 폴리스티렌을 포함한 모르타르를 벽면에 발라줌으로써 간단히 단열층을 형성할 수 있는 환경 친화적이며 저렴한 비용의 건물 외벽의 단열방수 시공방법을 제공하고자 한다.In order to solve the above problems, the present invention includes waste foamed polystyrene, which is pulverized without applying a primer to a non-uniform wall surface such as a red brick masonry wall surface or a tile wall surface or a general mortar-finished wall with high cracking or uniformly grinding the wall surface.

본 발명의 건물 외벽의 단열방수 보수보강 시공방법은 단열 보수보강이 이루어질 외벽 벽면을 고압 세척하는 단계(S1)와 분쇄된 발포 폴리스티렌과 모르타르를 혼합한 단열 모르타르를 상기 세척된 벽면에 발라준 후 경화시켜 단열층을 형성하는 단계(S2)와 일 측면에 점착제가 도포 된 보강섬유를 상기 경화된 단열층의 표면에 부착하는 단계(S3)와 상기 경화된 단열층의 표면에 부착된 상기 보강섬유의 표면에 아크릴 탄성 방수재를 도포하는 단계(S4)와 상기 아크릴 탄성 방수재의 표면에 페인트를 도포하는 단계(S5)를 포함하여 이루어진다.Insulation waterproof repair reinforcement construction method of the building exterior wall of the present invention is the step of high pressure washing the outer wall wall to be insulated repair reinforcement (S1) and hardened after applying a thermal insulation mortar mixed with crushed expanded polystyrene and mortar on the washed wall surface Forming a heat insulation layer (S2) and attaching a reinforcing fiber coated with an adhesive on one side to the surface of the cured heat insulation layer (S3) and acryl on the surface of the reinforcement fiber attached to the surface of the cured heat insulation layer. It comprises a step (S4) of applying an elastic waterproof material and the step of applying a paint (S5) to the surface of the acrylic elastic waterproof material.
여기서 상기 단열층은 크게 분쇄된 발포 폴리스티렌과 모르타르로 구성된다. Here, the heat insulation layer is composed of largely crushed expanded polystyrene and mortar.
상기 발포 폴리스티렌은 통상 스티로폼이라고 불리는 것으로 3~5mm의 크기로 분쇄하여 사용한다. 특히 상기 발포 폴리스티렌은 특정 폐기물로 분류되어 폐기처리가 곤란했던 버려지는 폐 발포 폴리스티렌을 사용하여줌으로써 자원의 재활용은 물론 비용절감의 효과까지 얻을 수 있다. 상기 폐 발포 폴리스티렌은 5~15중량%가 포함되는데 이는 함량이 5중량% 이하일 경우에는 단열 성능이 저하될 염려가 있으며 15중량% 이상일 경우에는 부피가 커져 접착력이 약화되거나 모르타르 강도가 저하되어 보관시 제품의 층 분리 현상이 일어날 수 있기 때문이다. The expanded polystyrene is commonly referred to as styrofoam and is used by grinding to a size of 3 to 5 mm. In particular, the foamed polystyrene can be obtained by using waste foamed polystyrene that has been classified as a specific waste and difficult to be disposed of. The waste foamed polystyrene includes 5 to 15% by weight, which may be deteriorated when the content is 5% by weight or less, and when the amount is 15% by weight or more, the volume becomes large due to weakened adhesive strength or reduced mortar strength. This is because layer separation of the product may occur.
그리고 상기 모르타르는 발포 폴리스티렌 5~15중량%, 시멘트 40~60중량%, 물 10~30%, 석회석 1~5중량%, 탄산칼슘 5~18중량%, 파우더 폴리머(Powder polymer) 1~5중량%, 칼슘스테 아르산 0.1~0.5 중량%, 감수제 0.1~0.3중량% 으로 이루어지는데, 상기 모르타르에 부착력을 향상시키는 상기 파우더 폴리머가 첨가됨으로써 분쇄된 발포 폴리스티렌과 시멘트가 잘 혼합될 수 있게 해준다. And the mortar is 5 to 15% by weight of expanded polystyrene, 40 to 60% by weight of cement, 10 to 30% of water, 1 to 5% by weight of limestone, 5 to 18% by weight of calcium carbonate, 1 to 5 weight of powder polymer %, 0.1% to 0.5% by weight of calcium stearate, and 0.1% to 0.3% by weight of a reducing agent, and the powdered polymer is added to the mortar to improve adhesion, so that the crushed expanded polystyrene and cement can be mixed well.
상기 보강섬유는 벽면크랙과의 저항성을 높여주기 위해 사용되는데 보강섬유로는 유리섬유테이프, 부직포, 합성섬유, 천연섬유 중 어느 하나를 사용자의 선택에 따라 사용할 수 있다. 상기 유리섬유테이프, 부직포, 합성섬유, 천연섬유로 중 어느 하나로 된 보강섬유의 일 측면에는 점착제를 도포하여 줌으로써 상기 단열층이 경화된 다음 상기 보강섬유를 상기 경화된 단열층 벽면에 간단히 붙일 수 있어 시공을 더욱 용이하게 진행할 수 있게 해준다. 그리고 상기 아크릴탄성 방수제를 도포하는 공정 또한 쉽고 용이하게 진행할 수 있도록 도와준다.The reinforcing fibers are used to increase the resistance to the wall cracks as the reinforcing fibers can be used any one of the glass fiber tape, nonwoven fabric, synthetic fibers, natural fibers according to the user's choice. One side of the reinforcing fiber made of any one of the glass fiber tape, nonwoven fabric, synthetic fiber, and natural fiber furnace may be applied by applying an adhesive to cure the heat insulating layer, and then simply attach the reinforcing fiber to the hardened heat insulating layer wall surface. Make it easier to proceed. And the process of applying the acrylic elastic waterproof agent also helps to proceed easily and easily.
상기 아크릴탄성 방수제는 시멘트 20~35중량%, 감수제 0.1~0.5중량%, 규사 7호사 40~50중량%, 아크릴 수지 20~30중량%, 소포제 0.1~0.5 중량%, 증점제 0.1~0.5 중량%로 구성된다. 여기서 상기 아크릴 에멀젼은 유리전이온도가 -25℃ 이하인 것을 사용하여야 하는데 그 이유는 유리전이온도가 -25℃ 이상일 경우에는 부착력이 저하되기 때문이다. The acrylic elastic waterproofing agent is 20 to 35% by weight of cement, 0.1 to 0.5% by weight of reducing agent, 40 to 50% by weight of silica sand No. 7, 20 to 30% by weight of acrylic resin, 0.1 to 0.5% by weight of antifoaming agent, and 0.1 to 0.5% by weight of thickener. It is composed. Here, the acrylic emulsion should use a glass transition temperature of less than -25 ℃ because the adhesion strength is lowered when the glass transition temperature is -25 ℃ or more.
상기 페인트는 시공된 건물의 외측 벽면이 방수, 방오 기능을 가지며 광택이 날 수 있도록 칠해주는 마감 페인트로서 아크릴 에멀젼 50~70 중량%, 이산화티탄 15~30 중량%, 증점제 0.1~1 중량%, 소포제 0.1~0.5 중량%, 탄산칼륨 5~20 중량%, 수분산성 우레탄 경화제 5~10 중량%로 구성된다. 하지만 여기서 상기 이산화티탄과 탄산칼륨의 합한 함량이 20중량%를 초과할 경우 광택이 사라질 수 있으므로 상기 이산화티탄과 탄산칼륨의 총 중량은 20중량%이하로 구성하여 주는 것이 바람직하다. The paint is a finish paint that makes the outer wall of the constructed building waterproof, antifouling and polished. Acrylic paint 50-70 wt%, titanium dioxide 15-30 wt%, thickener 0.1-1 wt%, antifoaming agent 0.1 to 0.5% by weight, potassium carbonate 5 to 20% by weight, and water dispersible urethane curing agent 5 to 10% by weight. However, since the gloss may disappear when the total content of the titanium dioxide and potassium carbonate exceeds 20% by weight, the total weight of the titanium dioxide and potassium carbonate is preferably 20% by weight or less.
그리고 상기 수분산성 우레탄 경화제는 함량이 5중량% 이하일 경우에는 상기 페인트의 경화가 잘 되질 않아서 끈적끈적해지며 방수, 방오 성능이 저하될 수 있으며 함량이 10중량% 이상일 경우에는 우레탄 수지의 통상수산기(-OH)와 이소시아네이트기(-NCO)의 밸런스가 깨질 수 있으며, 물성이 저하되거나 비용이 증가할 염려가 있다. And when the content of the water-dispersible urethane curing agent is less than 5% by weight of the paint is not well hardened and becomes sticky and the waterproof, antifouling performance may be lowered, if the content is more than 10% by weight of the conventional hydroxyl group of the urethane resin ( -OH) and the balance of isocyanate group (-NCO) may be broken, there is a fear that the physical properties are lowered or the cost increases.
다음으로는 상기와 같이 구성되는 본 발명에 따른 건물 외벽의 단열방수 보수보강 시공방법의 바람직한 실시 예에 대하여 설명하기로 한다.Next, a description will be given of a preferred embodiment of the thermal insulation waterproof repair construction method of the building exterior wall according to the present invention configured as described above.
