Description
교면방수Water resistance
종래 알려진 교면에 대한 방수공법으로는 도막방수공법과 고무아스팔트 방수공법이 있다.As a waterproof method for the conventional bridges, there is a waterproof coating method and a rubber asphalt waterproofing method.
도막방수공법은 교량의 균열에 대처하지 못하고 아스콘과의 접착이 불량하고 공기가 지연되며 핀홀 현상발생및 두께불량의 문제가 있다.Coating waterproofing method does not cope with the crack of the bridge, poor adhesion with ascon, air delay, pinhole phenomenon and poor thickness.
중심보강재를 삽입한 고무화 아스팔트시트 방수공법의 경우,시트이음부의 수밀성부족과 토치등 열을 이용하여 가열하여 열융착시 직접 가열로 고무아스팔트의 물성변화가 초래되고, 시트와 콘크리트 구조체와 접착력부족으로 들뜸현상이 생겨 누수된 물이 시트방수 층아래로 흘러다니면서 콘크리트 균열부,이음부 등과같이 구조체의 취약부위에 방수하자가 발생 되었으며 상부 아스콘과의 밀림현상이나 분리현상이 발생되어 하자 발생율이 높다는 단점이 있다.In the case of waterproofing the rubberized asphalt sheet with the central reinforcement material, the watertightness of the sheet joint and the heat of the torch are used to heat it, resulting in a change in the properties of the rubber asphalt by direct heating when heat-sealed, and insufficient adhesion between the sheet and the concrete structure. As water leaked down and flowed down the sheet waterproofing layer, water-resistant defects occurred at the weak parts of the structure such as concrete cracks and joints, and the occurrence rate of defects was high due to the jungle or separation with the upper ascon. There are disadvantages.
이와같은 단점을 보완하고자 시트와 도막의 복합방수공법이 개발되었으나 상부 방수층으로 사용된 합성섬유 부직포가 아스콘과의 접착이 불량하고 아스콘 포설시에 높은 온도로 인하여 열수축되어 아스콘에 균열이 발생하며 방수 방수층이 종이 펠트인 경우는 도막방수층과의 함침이 어렵고 도막층과의 분리현상이 발생하는 등의 문제가 있었다.In order to make up for these drawbacks, the composite waterproofing method of sheet and coating film was developed, but synthetic fiber nonwoven fabric used as upper waterproof layer was poorly bonded with ascon and thermal contraction due to high temperature when laying ascon caused cracks in ascon. In the case of this paper felt, impregnation with the coating layer was difficult, and there was a problem of separation with the coating layer.
상부 아스콘과 결합이 잘되면서 하부 콘크리트 구조체와 접착이 잘되고 밀림현상이 발생해도 방수층이 파단되지 않고 시공이 단순한공법As it is well bonded with the upper ascon, it adheres well to the lower concrete structure, and even if a jungle phenomenon occurs, the waterproof layer does not break and the construction is simple.
시트의 하부에는 도막방수의 효과를 주면서 콘크리트와 완벽하게 결합하는 비가황 부틸고무시트층을 구성하고 상부면에는 표면보호층 아스콘과 결합이 잘되는 개질아스팔트를 적층하여 일체화 시켜 하나의 시트로 제조The lower part of the sheet provides the effect of waterproofing the film, and forms a non-vulcanized butyl rubber sheet layer that perfectly combines with concrete, and the upper surface is integrated with laminated modified asphalt which is well bonded with the surface protection layer ascon.
밀림현상으로 인한 시트층 들뜸이나 파단이 없고 상부에는 개량아스팔트층을 구성하여 아스콘과 결합이 잘되어 균열이 발생하지 않고 하부에는 바닥콘크리트와 강력결합하는 부틸고무를 적층하여 일체화 시켜 시트방수와 도막방수의 효과를 상하부로 나누어 동시에 극대화 시키고 시공성이 우수하고 하자율이 감소한다The sheet layer is not lifted or broken due to the jungle phenomenon, and the improved asphalt layer is formed on the upper part, so that it is well bonded with the ascon, so that no crack occurs, and the lower part is laminated with the butyl rubber which is strongly bonded to the bottom concrete to waterproof the sheet and waterproof the coating film. The effect is divided into upper and lower parts and maximized at the same time, the workability is excellent and the defect rate decreases.
본고안의 자착식교면방수시트(100)의 구성은 고무화아스팔트층(40),중심보강재층(30),비가황부틸고무시트층(20),이형지층(10)으로 적층되어 구성된다.The structure of the self-adhesive intersecting
보강재는 섬유망,TPU필름, 부직포.직포 등에서 1종이상 선택하여 사용할수 있다.The reinforcing material can be used by selecting one or more kinds of fiber net, TPU film, nonwoven fabric and woven fabric.
상기 비가황부틸고무시트층(20)은 비가황계 부틸고무 18 중량%, 카본 보강제 10 중량%, 가소제 1 중량%, 첨가제 25 중량%, 및 중탄 충전제 46중량%를 혼합하여 균일 도포하여 이루어진 것이다. The non-vulcanized butyl rubber sheet layer 20 is made by uniformly mixing 18% by weight of non-vulcanized butyl rubber, 10% by weight of carbon reinforcing agent, 1% by weight of plasticizer, 25% by weight of additives, and 46% by weight of bicarbonate filler.
상기 충전제는 탈크, 카본블랙, 탄산칼슘, 및 이들의 혼합물로 이루어진 군으로부터 선택하여 사용할 수 있다. 상기 가소제는 디옥틸프탈레이트, 디부틸프탈레이트, 디이소노닐프탈레이트, 사이트릭애시드에스테르, 텍사놀/에스테르알콜 등이 사용될 수 있으며 이들은 단독 또는 1 종 이상 혼합하여 사용할 수 있다. The filler may be selected from the group consisting of talc, carbon black, calcium carbonate, and mixtures thereof. The plasticizer may be used dioctylphthalate, dibutyl phthalate, diisononyl phthalate, citric acid ester, texanol / ester alcohol and the like, these may be used alone or in combination of one or more.
또한 상기 첨가제는 로진(송진), 활제로서 스테아린산 등을 포함할 수 있으며 이들은 단독 또는 1 종 이상 혼합하여 사용할 수 있다. In addition, the additive may include rosin (rosin), stearic acid as a lubricant and these may be used alone or in combination of one or more.
이와 같이 구성된 비가황부틸고무시트층(20)은 온도 변화에 민감하지 않고 내구성 내후성이 좋으며 모든 종류의 바탕기재에 대하여 강력한 접착력을 가지며 산이나 알카리와 반응하지 않고 탄성 및 신율이 좋기 때문에 바탕기재의 균열에 따라 거동하며 자기 보수성을 지니기 때문에 방수층 파단을 방지할 수 있다. The non-vulcanized butyl rubber sheet layer 20 thus constructed is not sensitive to temperature changes, has good durability and weather resistance, has strong adhesion to all kinds of base materials, and does not react with acids or alkalis and has good elasticity and elongation. It behaves according to cracks and has self-maintenance to prevent breakage of the waterproof layer.
따라서 상기 비가황부틸고무시트층(20)이 콘크리트 바탕기재 전면에 밀착될 수 있어 물기가 상기 시트와 바탕기재 사이에 타고 돌지 않으며 방수층과 바탕기재가 함께 천공이나 크랙이 생기지 않는 이상 누수로 이어질 확률이 감소된다. Therefore, the non-vulcanized butyl rubber sheet layer 20 may be in close contact with the front surface of the concrete base material, so that water does not ride between the sheet and the base material, and the waterproof layer and the base material are not likely to lead to leakage unless a puncture or crack occurs together. Is reduced.
설사 천공이 일어난다 하더라도 누수부분만 시트를 덧대어 보수 하므로 보수가 용이하다. Even if perforation occurs, it is easy to repair because only the leaked part is covered with a sheet.
본고안의 교면 방수공법은, 방수바탕면(50)을 깨끗이 청소하고 부틸고무시트 전용프라이머(60)를 도포하여 건조시킨후 상기 자착식교면방수시트이음부를 겹쳐손이나 로울러등으로 눌러주어 접착시키고 조인트부분에 보강시트를 시공 시공을 완료한후 아스콘을 포설하는 것으로 구성된다The bridge waterproofing method of this paper cleans the waterproof surface 50, applies a butyl rubber sheet primer 60 and dries it, and then presses the self-adhesive cross-coated waterproof sheet joint with a hand or a roller, and glues it to the joint. It consists of laying ascone after the construction of reinforcement sheet is completed.
