본 발명은 방수구조에 관한 것으로, 더욱 상세하게는 각종 구조물의 표면에 경량의 방수재료를 덧씌우기 공법으로 시공함으로써, 구조물을 손상시킴 없이 반영구적인 방수시공이 가능할 뿐만 아니라 구조물의 내외부 온도차로 인한 방수층 내면의 결로현상이 방지되며, 또한 시공 후 보수 및 유지관리가 용이한 경량 방수층을 이용한 방수 시공구조에 관한 것이다.The present invention relates to a waterproof structure, and more particularly, by installing a lightweight waterproof material on the surface of various structures, it is possible not only semi-permanent waterproof construction without damaging the structure, but also waterproof layer due to the temperature difference between the inside and outside the structure Condensation of the inner surface is prevented, and also relates to a waterproof construction structure using a lightweight waterproof layer that is easy to repair and maintain after construction.

일반적으로 각종 건축물을 포함하여 대부분의 구조물은 콘크리트 재료로 이 루어지며, 이 같은 콘크리트 구조물은 시공 후 수분의 증발과 함께 경화하는 과정에서 내외부에 미세균열이 생성된다. 이러한 균열은 기간이 경과 되면서 구조물 자체의 하중이나 기타 외력에 의해 그 규모가 점차 확대되는 것이며, 이렇게 확대된 균열부를 통해 빗물 등이 스며들어 구조물 내부로 누수현상이 발생하게 된다. 따라서, 이러한 누수현상을 방지하기 위해 구조물에 방수시공을 하게 되는 것이다.In general, most structures, including various buildings, are made of concrete materials. Such concrete structures generate microcracks both inside and outside during the curing process with evaporation of water after construction. These cracks are gradually expanded in size due to the load or other external force of the structure itself, and the water leaks into the structure due to the infiltration of rainwater through the enlarged cracks. Therefore, in order to prevent such leakage phenomenon is to be waterproof construction.

종래의 방수시공 방법으로는, 균열이 발생된 구조물의 표면을 깨내고 균열부위를 채운 후, 상기 깨어낸 부분을 새로운 콘크리트로 덧씌워 시공하는 방법을 사용하였다. 하지만, 이 같은 방수공법은 구조물의 일부를 깨내는 과정에서 구조물에 새로운 균열이 발생될 우려가 있어 오히려 누수부분의 확대를 가져오는 역기능이 초래되며, 구조물에는 여러 가지 이유로 균열부위가 계속적으로 진행되므로 그때마다 기존의 방수시공물을 보수하거나 새로 방수시공을 해야하는 것이었다. 즉, 상기 공법으로는 균열에 의한 누수문제를 근본적으로 해소할 수 없는 것이었으며, 또한 이 같은 방수공법은 공사과정에서 상당한 소음, 분진 및 폐자재를 발생시켜 주변환경에 악영향을 끼치게 되고, 그 시공방법이 복잡하여 공사기간의 장기화 및 비용의 증가를 가져오는 것이었다.As a conventional waterproof construction method, after breaking the surface of the structure in which the crack is generated and filling the cracked portion, a method of constructing the cracked portion covered with new concrete was used. However, this waterproofing method may cause new cracks in the structure in the process of breaking a part of the structure, and thus cause a dysfunction which leads to an enlargement of the leaked part. At that time, the existing waterproof construction had to be repaired or a new waterproof construction had to be performed. That is, the above method was not able to fundamentally solve the leakage problem due to cracks, and such a waterproof method generates considerable noise, dust, and waste materials during the construction process, which adversely affects the surrounding environment. The method was complicated, resulting in longer construction periods and increased costs.

상기와 같은 시공상의 난점으로 인하여, 최근에는 구조물의 균열 부위에 우레탄 고무계나 아크릴 고무계 내지는 클로로프렌 고무계 등의 액상 재료를 롤러, 솔 또는 분무기 등의 공구를 사용하여 균열 부위에 덧씌우는 도막방수 공법이 널리 이용되고 있다.Due to the difficulties in construction as described above, in recent years, a coating film waterproofing method is widely used to cover liquid cracking materials such as urethane rubber, acrylic rubber or chloroprene rubber at the cracking portion of the structure by using a tool such as a roller, brush or sprayer It is used.

그러나, 이 같은 도막방수 공법은 그 공사방법이 간단하여 공기가 단축되는 등의 장점을 가진 반면에 기타 여러 가지 문제점을 발생시키는 것이었다.However, the coating film waterproofing method has advantages such as shortening of the air due to its simple construction method and causing various other problems.

즉, 상기 도막방수 공법에 사용되는 방수소재 들은 얇은 피막구조를 이루면서 구조물의 균열부위를 외부와 차단하는 것이므로, 구조물의 내측으로 뻗어있는 작은 규모의 균열부위는 그 균열상태를 그대로 유지하는 것이다. 이때, 상기 방수소재가 피막된 구조물의 내외부에는 온도차가 존재하는 것이므로, 외부의 차가운 공기와 구조물 내측의 따뜻한 공기와의 온도차에 의하여 상기 방수소재의 내면에 물방울이 맺히는 결로현상이 발생하며 들뜸 현상이 초래된다.That is, the waterproofing materials used in the waterproofing method of the coating film form a thin film structure to block the cracked portion of the structure from the outside, so that the small scale cracked portion extending into the structure maintains the cracked state. In this case, since the temperature difference exists inside and outside the structure coated with the waterproof material, condensation occurs when water droplets form on the inner surface of the waterproof material due to the temperature difference between the outside cold air and the warm air inside the structure. Caused.

이에 따라, 상기 결로현상에 의한 물방울이 구조물의 균열 틈새로 스며들면서 구조물의 강성을 약화시키는 결과를 가져오게 되고, 또한 이 같은 물방울이 콘크리트 구조물의 골조를 이루는 철근에 유입되어 부식현상을 유발하며 구조물의 수명을 단축시키는 요인으로 작용하는 것이었다.As a result, the condensation drops into the cracks of the structure, resulting in a weakening of the rigidity of the structure. Also, the water droplets enter the reinforcing bars of the concrete structure and cause corrosion. It was to act as a factor to shorten the life of the.

또한, 상기와 같이 구조물의 균열부위를 방수소재로 피복한 후, 그 위에 새로운 콘크리트를 타설하는 방법이 많이 이용되고 있지만, 이는 구조물에 가해지는 하중의 증가를 초래하여 구조물의 강성약화 및 심한 경우 붕괴의 주원인으로 작용하는 것이었다.In addition, after coating the cracked portion of the structure with a waterproof material as described above, a new concrete is placed on it, but this leads to an increase in the load on the structure, weakening the rigidity of the structure and collapse in severe cases It was to act as the main cause.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창안된 것으로서, 균열이 발생된 구조물의 표면으로 방수층과 경량의 충진재가 덧씌워지는 공법으로 시공되어, 반영구적이면서 수밀성이 우수할 뿐만 아니라 그 시공, 보수 및 유지관리가 용이하여 작업성이 우수한 동시에 비용절감의 효과를 가져오는 경량 방수층을 이용한 방수 시공구조를 제공하는데 그 목적이 있다.The present invention was devised to solve the above problems, and is constructed by a method in which a waterproof layer and a lightweight filler are overlaid on the surface of a structure in which cracks have been generated, and are not only semi-permanent but excellent in watertightness.

본 발명은 또한, 구조물의 내외부 온도차에 의해 구조물 표면과 접한 방수층 내면으로 물방울이 맺히게 되는 결로현상을 억제하여 결로현상에 의한 물방울이 균열부위를 통해 누수되면서 철골조를 부식하거나 구조물의 강도를 저하시키는 현상이 미연에 방지되도록 하는 경량 방수층을 이용한 방수 시공구조를 제공하는데 다른 목적이 있다.The present invention also suppresses the condensation of water droplets on the inner surface of the waterproof layer in contact with the surface of the structure due to the temperature difference between the inside and the outside of the structure. Another object is to provide a waterproof construction structure using a lightweight waterproof layer to be prevented in advance.

그리고, 상기 경량충진재(30)는, 다양한 형태의 재료가 사용될 수 있겠으며, 이하 본 실시예를 기준하여 설명한다.In addition, the lightweight filler 30, various types of materials may be used, will be described below with reference to the present embodiment.

본 실시예에서는 상기 경량충진재(30)로 에폭시 몰탈을 사용하였다. 즉, 상기 에폭시 몰탈은 에피클로로히드린과 비스페놀 A를 중합시킨 에폭시수지, 셀룰로즈와 알칼리 수용액 및 디에틸황산을 반응시켜 만든 메틸셀룰로즈유화제, 소포제, 경화제로 구성된 에폭시 방수제에 경량골재와 시멘트를 혼합하여 제조한다. 이때, 상기 에폭시 방수제의 특성에 의해 상기 에폭시 몰탈은 내약품성, 내식성, 동결융해저항성이 우수한 것이다.In this embodiment, epoxy mortar was used as the lightweight filler 30. That is, the epoxy mortar is a mixture of lightweight aggregate and cement in an epoxy waterproofing agent consisting of an epoxy resin polymerized by epichlorohydrin and bisphenol A, a cellulose, an alkali aqueous solution and a methyl cellulose emulsifier, an antifoaming agent, and a curing agent.

상기 에폭시 몰탈을 구성하는 재료 및 그 제조공정에 대해 보다 구체적으로 설명한다.The material which comprises the said epoxy mortar and its manufacturing process are demonstrated more concretely.

먼저, 상기 에폭시 방수제는 메틸셀룰로즈를 수분산계로 사용한 수용성 에폭시 수지 조성물과 저점도의 수용성 폴리아미드 경화제 조성물을 1:1의 중량비로 혼합하여 제조하여 에폭시 에멀젼을 준비하고, 여기에 시멘트와 경량골재를 혼합한다. 이때, 상기 시멘트는 상기 에폭시 방수제 중량의 1.5~2배를 혼합하며, 상기 경량골재는 에폭시 중량의 3~3.5배를 혼합하되, 이 같은 경량골재는 입경 2~3mm의 것을 사용한다.First, the epoxy waterproofing agent is prepared by mixing a water-soluble epoxy resin composition using methyl cellulose as a water dispersion and a low viscosity water-soluble polyamide curing agent composition in a weight ratio of 1: 1 to prepare an epoxy emulsion, and cement and lightweight aggregate Mix. At this time, the cement is mixed 1.5 to 2 times the weight of the epoxy waterproofing agent, the light weight aggregate is mixed 3 to 3.5 times the weight of the epoxy, such lightweight aggregate uses a particle size of 2 ~ 3mm.

As polypropylene fiber is added to act as a tensile reinforcing material, it is possible to reduce the occurrence of shrinkage cracking of epoxy mortar.

상기와 같이 구성되는 본 발명에 따른 방수 시공구조의 작용을 설명한다.The operation of the waterproof construction according to the present invention configured as described above will be described.

먼저, 구조물에 발생된 균열의 규모를 고려하여 통기성 방수층(10)의 타설량을 결정한 후, 일정량(대략 전체의 50% 정도)의 제1경량몰탈(10a)을 구조물(100) 상부에 타설하고, 그 위에 관통공(21)이 천공된 알루미늄 재질의 균열억제망(20)을 평평하게 펴서 설치한 후, 상기 관통공(21)에 경량몰탈이 완전 충진되도록 상기 거 치된 균열억제망(20) 위에 적정량의 제2경량몰탈(10b)을 제1경량몰탈(10a)과 일체화되도록 추가 타설하여 통기성 방수층(10)을 완성하게 된다.First, the amount of the breathable waterproof layer 10 is determined in consideration of the size of the cracks generated in the structure, and then a predetermined amount (about 50% of the total) of the first lightweight mortar 10a is placed on the structure 100. After installing the flattening the crack suppression net 20 made of aluminum perforated through the through-hole 21 thereon, the crack suppression net 20 is placed so that the light-weight mortar is completely filled in the through-hole 21. The second lightweight mortar (10b) of the appropriate amount is further poured to be integrated with the first lightweight mortar (10a) to complete the breathable waterproof layer (10).

그리고, 상기 제2경량몰탈(10b)의 상측으로 경량충진재(30)를 타설하여 방수시공을 마감하게 되는 것으로, 상기 경량충진재(30)는 탁월한 방수기능 외에도 내약품성, 내식성 동결융해저항성이 우수함에 따라 견고한 방수시공이 가능하게 된다. 또한, 상기 경량충진재(30)에 의해서 상기 통기성 방수층(10)은 외부의 충격으로부터 보호된 채 보다 안정된 설치 상태를 유지하는 것이다.In addition, by placing the lightweight filler 30 on the upper side of the second lightweight mortar (10b) to finish the waterproof construction, the lightweight filler 30 is excellent in chemical resistance, corrosion resistance and freeze-thawing resistance in addition to excellent waterproof function. As a result, a solid waterproof construction is possible. In addition, the breathable waterproof layer 10 by the lightweight filler 30 is to maintain a more stable installation state protected from external impact.

이렇게 시공되는 본 발명의 방수 시공구조는, 균열이 발생된 구조물(100)의 표면에 경량의 재료를 덧씌우는 시공방법이므로, 방수시공 과정에서 구조물(100)의 일부를 꺼낸 후 충진재를 주입하는 등의 복잡한 시공을 요하지 않아 시공이 간편한 것이며, 또한 방수시공 과정에서 구조물(100)에 충격을 전달하지 않음에 따라 방수시공 중 오히려 균열이 확대되는 등의 부작용이 사전에 방지되는 것이다.Thus, the waterproof construction of the present invention is a construction method of overlaying a lightweight material on the surface of the structure in which the crack is generated, and thus injecting a filler after taking out a part of the structure 100 during the waterproof construction process. It is easy to construct because it does not require a complicated construction of, and also does not transmit the impact to the structure 100 in the waterproof construction process, side effects such as the expansion of cracks during waterproof construction is rather prevented in advance.

또한, 구조물(100)의 균열부위만을 일시적으로 방수시키는 소극적 의미의 방수공법이 아니고 구조물(100)의 표면을 완전하게 방수처리하는 것이므로, 한차례 시공하고 나면 그 내측으로 위치하는 구조물에 균열이 확대, 생성되더라도 별다른 보수공사가 필요치 않게 된다. 또한, 방수구조의 일부분에 문제가 생겨 누수문제가 발생되더라도, 그에 해당하는 좁은 면적의 경량충진재(30)를 교체하는 간단한 시공을 통해 보수가 가능한 것이므로 유지보수가 용이한 것이다.In addition, since the surface of the structure 100 is completely waterproofed, rather than the passive method of temporarily waterproofing only the cracked portion of the structure 100, the crack is expanded to the structure located inside the structure once. If created, no renovation is required. In addition, even if a problem occurs in a part of the waterproof structure leaks, it is easy to maintain because it is possible to repair through a simple construction to replace the lightweight filler 30 of the corresponding narrow area.

상기한 실시예에 의하여 알 수 있는 바와 같이, 본 발명에 따른 방수 시공구 조는, 경량몰탈 사이에 균열억제망을 삽입하고 그 위에 경량충진재를 입혀 구성함으로써, 구조물의 훼손 없이 간편한 작업을 통해 완벽한 방수시공을 할 수 있으므로, 방수기능의 극대화를 가져올 뿐만 아니라 시공상의 안정성이 증대되는 동시에 공사기간을 단축시킬 수 있는 효과가 있다.As can be seen by the above embodiment, the waterproof construction structure according to the present invention, by inserting a crack suppression network between the light-weight mortar and by coating a light filler on it, perfect waterproof through simple operation without damage to the structure Since the construction can be carried out, not only the maximization of the waterproof function but also the stability of construction is increased, and the construction period can be shortened.

또한, 상기 균열억제망이 방수층을 지지하는 역할을 하여 이를 통해 방수층의 균열이 억제되므로 누수 원인을 1차적으로 차단할 수 있고, 상기 균열억제망은 알루미늄 재질로 제작할 경우 난방 파이프의 열을 방 전체에 골고루 전달함으로써 난방 유지비를 절감할 수 있는 효과를 갖게 된다.In addition, the crack suppression network serves to support the waterproofing layer, thereby preventing the cracking of the waterproofing layer, thereby preventing the leakage of water primarily. When the crack suppression network is made of aluminum, the heat of the heating pipe is applied to the entire room. By delivering evenly, the heating maintenance cost can be reduced.

또한, 방수시공 후엔 결로현상이 발생되지 않아 결로현상으로 인한 몰탈의 훼손 및 누수문제를 방지함으로써 신뢰감 있는 방수구조의 제공이 가능하게 되는 것이다.In addition, condensation does not occur after waterproofing, thereby preventing damage and leakage of mortar due to condensation, thereby providing a reliable waterproof structure.
