Description
본 발명은 콘크리트 구조물의 수축 이음재 및 그 이음재의 시공방법, 보다 상세하게는 길이가 긴 콘크리트구조물을 양생시키는 과정의 건조수축과 완성 후 온도수축으로 인하여 발생되는 균열을 특정부위로 집중되도록 유도하는 수축이음 즉 균열유발줄눈을 형성할 때 콘크리트 구조물에 있어 균열 홈과 균열을 형성하는 균열유발 간격판의 장치와 시공방법에 관한 것이다.The present invention is a shrinkage joint material of the concrete structure and the construction method of the joint material, more specifically, shrinkage to induce cracks generated by drying shrinkage and temperature shrinkage after completion of curing the long concrete structure to concentrate to a specific site The present invention relates to a device and a construction method of crack inducing spacers that form crack grooves and cracks in concrete structures when forming joints, ie, crack inducing joints.
일반적으로 콘크리트 구조물의 시공과정에서 발생하는 응력 및 균열발생 여부 및 발생한 균열폭과 위치를 억제하고 구조물의 작용하중에 대한 저항성 및 환경조건에 대한 내구성 등 필요한 기능을 확보할 수 있도록 적절한 조치를 강구하도록 하고 있다. 따라서 매스콘크리트에 대한 균열 대책 및 조치는 시공단계만으로는 대응할 수 없는 경우가 많아, 설계단계에서 균열제어를 위한 충분한 고려를 반드시 해야 할 필요가 있다. In general, it is necessary to take appropriate measures to control the stress and cracks occurring during the construction of concrete structures, to control the crack width and location, and to secure necessary functions such as resistance to the working load of the structure and durability against environmental conditions. have. As a result, cracking measures and measures for mass concrete are often unresponsive by the construction stage alone. Therefore, it is necessary to take sufficient consideration for crack control in the design stage.
이에 대해 구조물의 길이방향에 일정간격으로 단면감소부분을 만들어 그 부분에 균열을 유발시켜 기타 부분에서의 균열발생을 방지함과 동시에 균열개소에서의 사후 조치를 쉽게 하는 수축이음 방법으로 예정 개소에 균열을 확실하게 유도하기 위해서 도 2의 (61)과 같이 균열유발 수축이음 간격을 4∼9ｍ 정도의 기준으로 형성하도록 제시하고 있으나 ,구체적인 재질 및 시공방법은 규정하고 있지 않다.On the other hand, by creating a section of reduced section at regular intervals in the longitudinal direction of the structure, causing cracks in the sections to prevent cracks in other sections, and at the same time, it is a shrink joint method that facilitates follow-up at the cracks. In order to reliably induce this, as shown in (61) of Figure 2 is proposed to form a crack-induced shrinkage joint interval of about 4 ~ 9m, the specific material and construction method is not specified.
대체적으로 매스콘크리트의 균열방지 혹은 균열이 발생하는 위치와 그 폭을 제한하는 것을 포함한 균열제어 방법으로서는 설계, 재료의 선정, 시공방법 등 여러 가지 방법이 있으나, 일반적으로 매스콘크리트 구조물 등에 발생하는 온도균열을 재료 및 배합의 대책에 의해 제어하는 것은 시공방법이 복잡하고 과다한 설치비용이 소요되어 현실적으로 적용되지 못하고 있는 실정이고, 재료 및 시공방법에 의한 방식은 수축이음 줄눈(40)만 형성시키거나, 균열유발 줄눈이 설계상에 도면에 누락되는 등 시공과정에 검토되지 않아 매스콘크리트 구조물에 균열이 많이 발생하여 누수 되거나 균열 보수를 반복 시행하는 실정이다. 이러한 보수공법은 일반적으로 에폭시, 폴리에스테르 등 수지재료에 의한 표면처리 · 충전 및 주입공법이 사용되고 있으며, 막대한 보수비용이 소요되고 있다.In general, there are various methods of crack control including crack prevention of mass concrete or limiting the location and width of cracks, such as design, material selection, and construction methods. However, in general, temperature cracking occurs in mass concrete structures. Control by the measures of material and compounding is a situation in which the construction method is complicated and excessive installation cost is not practically applied, and the method by the material and the construction method forms only the shrinkage joint 40 or cracks. As the induced joints are missing from the drawings in the design, they are not examined in the construction process, so many cracks are generated in the mass concrete structure and water leaks or crack repairs are repeatedly performed. In general, such a repair method is a surface treatment, filling, and injection method using a resin material such as epoxy and polyester, and enormous repair costs are required.
본 발명의 목적은 균열예정개소에 균열을 확실하게 유도하는 균열유발 수축이음 장치를 시공함으로서 줄눈(40)만으로는 유도될 수 없는 수축이음부의 콘크리트 내부에 확실하게 단면 결손부를 형성하는 장치와 시공방법을 제시함으로서 설치가 간편하고 경제적으로 구조물의 필요한 기능 및 품질의 손상을 미연에 방지 할 수 있는 콘크리트 구조물의 균열유발 수축이음 장치 및 시공방법을 제공하는데 목적이 있다. An object of the present invention is to install a crack-induced shrinkage joint device that reliably induces cracking at a site to be cracked, and a device and a construction method for reliably forming cross-sectional defects in the concrete of the shrinkage joint which cannot be induced by the joint 40 alone. The purpose of the present invention is to provide a crack-induced shrinkage joint device and a construction method of concrete structures that can easily install and economically prevent damage to the required function and quality of the structure.
