Abstract
Description
본 발명은 교량 및 터널 양측의 연결부등에 설치되는 탄성콘크리트를 이용한 신축 이음 구조물에 관한 것으로 특히 폴리에틸렌 화합물인 압축, 인장, 전단 응력이 높은 신축 이음재를 이용하여 구조물의 거동을 흡수하도록 설치되는 탄성 콘크리트를 이용한 신축 이음 구조물에 관한 것이다.The present invention relates to an elastic joint structure using elastic concrete, which is installed on the bridges and the connection of both sides of the tunnel. In particular, an elastic concrete is installed to absorb the behavior of the structure by using a polyethylene joint having high compression, tensile and shear stresses. It relates to a stretch joint structure used.
일반적으로 교량의 연결부나 터널 양측의 연결부는 반복되는 차량의 통행과 기후에 따른 온도변화에 의하여 반복적인 충격하중 및 진동하중 그리고 수축 및 팽창에 의한 스트레스를 받게 된다. 이에 따라 단부에 균열이 발생하게 된다.In general, the bridge connection or both sides of the tunnel are subjected to repeated impact loads, vibration loads, and stresses from contraction and expansion due to repeated vehicle traffic and climate temperature changes. This results in cracks at the ends.
이러한 균열 부위를 보강하기 위하여 종래에는 구체 콘크리트의 양단 상면 일측을 절개하고 이에 탄성콘크리트를 채워 양생한 후 이들 사이에 자외선 차단제가 함유되어 내후성이 강하고 내화학성이 우수하며, 신축성이 구비된 신축 이음재(Ethylene Vinyl Acetate Low Density Polyethylene Copolymer Foam)를 에폭시 접착제로 접착하여 줌으로써 구조물의 심한 움직임, 마모, 비틀림, 부등침하, 지진 등 구조적 역학거동(압축, 인장, 전단, 회전등)을 흡수하여 교량이나 터널 등 각종 구조물의 손상을 방지하도록 하였다.In order to reinforce these cracks, conventionally, one side of the upper surface of both ends of the concrete concrete is cut and cured by filling the elastic concrete thereafter, and a sunscreen is contained therebetween so that the weather resistance is strong and the chemical resistance is excellent. Ethylene Vinyl Acetate Low Density Polyethylene Copolymer Foam) is bonded with epoxy adhesive to absorb structural dynamics (compression, tension, shear, rotation, etc.) such as severe movement, wear, torsion, uneven settlement, and earthquake. To prevent damage to various structures.
반면에 이러한 신축 이음 구조물의 단부에 후타재로 시공된 탄성 콘크리트의 혼합 원료로 사용되는 에폭시 자체의 신율이 2wt% 내지 25wt%에 불과하여 이를 사용한 탄성 콘크리트의 신율 역시 미미한 수준에 불과하였던 것이다.On the other hand, the elongation of the epoxy itself, which is used as a mixed raw material of the elastic concrete constructed as a futa material at the end of the expansion joint structure, was only 2wt% to 25wt%, and the elongation of the elastic concrete using the same was also insignificant.
그러므로 탄성 콘크리트로 된 신축 이음부에 반복적으로 가하여 지는 내충격, 내진동능력이 부족하므로 쉽게 손상되어 균열, 깨짐 등이 발생하고 잦은 보수 공사가 불가피하며, 이 경우 부분 보수만으로는 박리 현상을 방지할 수 없으므로 전체적인 보수 공사가 불가피하여 보수 비용이 과다하게 소요되는 문제점이 있다.Therefore, the impact resistance and vibration resistance that are repeatedly applied to elastic joints made of elastic concrete are insufficient, so they are easily damaged, causing cracks and cracks, and frequent repair work is inevitable. In this case, partial repair alone cannot prevent the peeling phenomenon. There is a problem that the overall repair work is inevitable, so excessive cost of repair.
또한, 이러한 잦은 보수는 교량 및 터널의 수명 단축을 초래하게 되며, 도료 이용률의 저하가 불가피하게 되는 등의 많은 문제점이 있는 것이다.In addition, such frequent repairs cause shortening of bridges and tunnels, and there are many problems such as a reduction in paint utilization rate.
본 발명의 목적은 이러한 문제점을 해결하기 위하여 교량 및 터널 양측 등 각종 시설물의 연결부위에 시공되는 탄성 콘크리트의 신율을 크게 향상시킬 수 있도록 한 탄성 콘크리트를 이용한 신축 이음 구조물을 제공함에 있다.It is an object of the present invention to provide a stretch joint structure using elastic concrete to significantly improve the elongation of the elastic concrete that is constructed on the connection portion of various facilities such as bridges and tunnels to solve these problems.
도1은 일반적인 교량이나 터널의 신축 이음 구조물을 보인 사시도.1 is a perspective view showing the expansion joint structure of a typical bridge or tunnel.
이러한 본 발명의 목적은 각종 시설물의 연결부위에 탄성 콘크리트로 채움부를 형성하여 양생하고 이들사이에 신축 이음부를 넣고 접착시켜서 된 공지의 신축 이음 구조물에 있어서 후타재인 탄성 콘크리트의 신율을 크게 향상시켜 줄 수 있도록하기 위하여 변성 에폭시 계열의 것으로 하여서 된 신축 이음 구조물을 제안한다.The object of the present invention can greatly improve the elongation of elastic concrete, which is a futa material, in a known expansion joint structure formed by forming and curing a filling portion with elastic concrete at a connection part of various facilities and putting expansion joints therebetween. In order to ensure this, we propose expansion joint structures made of modified epoxy series.
이에 따라 본 발명은 구조적 역학 거동을 효과적으로 흡수할 수 있게 되어 보수 횟수를 감소시켜 시설 보수 관련 비용을 절감할 수 있게 되는 등의 효과가 있다.Accordingly, the present invention can effectively absorb the structural dynamics to reduce the number of repairs to reduce the cost associated with the maintenance of the facility.
이러한 본 발명을 첨부된 도면을 참조하여 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail with reference to the accompanying drawings as follows.

이와 같이 하여 얻은 레진과 경화제는 후타재 시공을 요하는 장소에서 1:1로 교반하여 변성 에폭시를 제조한 후 규사로 된 골재와 혼합하되 1:3 내지 1:4의 비율이 되도록 하여 교반한다.The resin and hardener thus obtained were stirred at a place requiring futa material construction in a 1: 1 manner to prepare a modified epoxy, and then mixed with aggregates made of silica sand to be in a ratio of 1: 3 to 1: 4.
이어서 구체 콘크리트를 절단하여 만든 공간이나 기존 조인트 채움재 및 마감제를 제거하여 얻은 공간에 후타재인 탄성 콘크리트를 채워 넣고 대기중에 방치하면 경화되는 것이며, 이와 같이 하여 경화된 탄성 콘크리트와 신축 이음재를 에폭시 접착제로 접착하며, 이때 신축 이음재의 폭을 탄성 콘크리트 사이의 폭보다 25% 넓은 규격을 사용하여 강제 삽입하고, 후타재의 표면보다 약 4mm 이상 낮게 설치하여 줌으로서 양측의 구체 콘크리트가 접근하는 경우에도 신축 이음재가 외부로 노출되면서 마모되는 일이 없도록 한다.Subsequently, the space obtained by cutting concrete concrete or the space obtained by removing the existing joint fillers and finishes is filled with futon material and then left in the air to harden. Thus, the hardened elastic concrete and the expansion joint are bonded with epoxy adhesive. At this time, the width of the expansion joint is forced to be inserted using a standard that is 25% wider than the width between the elastic concrete, and installed about 4mm lower than the surface of the futa member to expand the expansion joint even when both concrete concrete approaches. Do not wear while exposed.
이와 같이 하여 얻은 본 발명에 의한 신축 이음 구조물은 탄성 콘크리트의 신율이 약 12% 내지 18% 이상으로 되면서도 우수한 기계, 물리적 성질 및 접착강도, 내막류성, 내후성, 전기 절연성면에서 우수한 물리적 성능을 가진다.The expansion joint structure according to the present invention thus obtained has excellent physical performance in terms of excellent mechanical, physical properties and adhesive strength, film flow resistance, weather resistance, and electrical insulation while having an elongation of elastic concrete of about 12% to 18% or more.
