Description

가시설용 띠장{H beam wale}Temporary stripe {H beam wale}
본 발명은 가시설용 띠장에 관한 것으로, H 빔의 양단부에 각각 단부조립체가 일체로 고정되고, H 빔의 일부가 콘크리트에 의해 매립된 구조를 가짐으로써, H 빔과 콘크리트의 강성의 결합으로 보더 높은 토압을 견딜 수 있고, 이로 인해 스트럿의 설치 개수를 줄일 수 있는 등 시공의 효율성이 증대된 가시설용 띠장에 관한 것이다.The present invention relates to a strip for temporary equipment, wherein the end assemblies are integrally fixed to both ends of the H beam, and a portion of the H beam is embedded by concrete, so that the rigidity of the H beam and the concrete is higher. The present invention relates to a strip for temporary equipment, which can withstand earth pressure and thereby reduce the number of installation of struts, thereby increasing construction efficiency.
도로, 건축물 등의 구조물의 시공하기 위하여 지반을 굴착하고, 굴착된 지반이 붕괴되지 않도록 이를 지지하는 가시설이 필요하다. 가시설은 주로 흙막이 구조이고, 일정 간격으로 수직으로 박음된 형강(H 빔, H-pile)과, 상기 형강의 사이를 연결하여 공간을 메워 붕괴를 방지하는 토류판, 상기 형강과 토류판을 지지하는 것으로 다수개의 형강과 수직으로 지지하도록 설치되는 띠장과, 서로 마주보는 맞은편 형강에 각각 단부가 접촉지지되게 설치되거나 띠장과 띠장의 사이에 설치되는 스트럿(strut)과, 띠장과 스트럿 등의 사이에 설치되는 잭(Jack) 등으로 구성된다.In order to construct a structure such as a road or a building, it is necessary to excavate the ground, and to provide a temporary facility for supporting the excavated ground so as not to collapse. Temporary facility is mainly made of earthen structure, and is connected to the section steel (H beam, H-pile) vertically inserted at regular intervals, and supports the earth plate, which fills the space to prevent collapse, and supports the section steel and the earth plate. A band installed vertically to support the two sections, struts provided between the opposite sections of the two sections facing each other, or struts provided between the bands and the bands, and between the bands and the struts, etc. Jack or the like.
그리고 상기 띠장의 강성을 증대시키기 위하여 내부에 강관을 설치하거나, 강관과 강관의 내부에 삽입되는 강선을 설치하여, 띠장과 더불어 지반을 견고히 지탱할 수 있도록 한 구조가 있다.And in order to increase the rigidity of the belt, there is a structure to install a steel pipe inside, or to install a steel wire and a steel wire inserted into the inside of the steel pipe, to support the ground firmly with the belt.
종래의 띠장은 H 빔의 단일 형상으로 되어있거나, 강관이나 강선 등의 보강재가 더 구비된 구조이다.Conventional strip length is a single shape of the H beam, or a structure further provided with reinforcing materials such as steel pipes and steel wires.
이와 같은 띠장을 토압을 충분히 견딜 수 있는 구조여야 한다. 그러나 종래의 경우는 단순히 H 빔의 형상에서 오는 강성을 그대로 이용하거나, 강관이나 강선의 설치로 보다 더 향상시킨 정도에 불과하였다.Such a strip should be of sufficient structure to withstand earth pressure. However, in the conventional case, the rigidity coming from the shape of the H beam is simply used as it is, or the degree of improvement is further improved by installing steel pipes or steel wires.
그러나 굴착 깊이와 면적이 넓어짐에 따라 토압이 상승되고, 수직으로 설치되는 H 빔 등의 수직 빔의 간격이 원가 절감이나 지반에 존재하는 암반 등의 이유로 인하여 그 간격이 큰 경우도 발생하게 된다.However, as the excavation depth and area are widened, the earth pressure is increased, and the spacing of vertical beams such as H beams installed vertically is large because of cost reduction or rocks present on the ground.
이와 같이 본 발명은 띠장의 강도를 증대시켜 어떠한 시공에 있어서도 적절하게 토압을 견딜 수 있도록 함에 목적이 있다.As described above, the present invention has an object to increase the strength of the strip, so that the earth pressure can be properly tolerated in any construction.
본 발명은 종래 H 빔을 단순 이용한 띠장의 강성을 증대시키기 위하여 H 빔의 일측이 콘크리트에 매립되어 일체로 형성된 구조를 제공한다. 그리고 잭과 같은 압착구를 고정하고, 압착구의 고정 위치를 조절할 수 있도록 한 단부조립체가 형성된 구조를 제공함으로써, 상기의 목적을 달성하게 된다. The present invention provides a structure in which one side of the H beam is integrally embedded in concrete in order to increase the rigidity of the strip using the conventional H beam. And by providing a structure in which the end assembly is formed so as to fix the crimp, such as a jack, and adjust the fixing position of the crimp, to achieve the above object.
본 발명에 의하면, 띠장의 H 빔이 콘크리트에 의해 일체로 형성됨으로써 H 빔과 콘크리트의 강성에 의하여 더욱 큰 토압을 견딜 수 있어 적용의 범위가 넓어지고, 단부조립체에 의하여 일정한 규격을 가진 H 빔을 이용하여 띠장을 구성하더라도 띠장의 단부를 서로 지지하는 압착구의 고정 위치를 알맞게 조절할 수 있게 된다. 그리고 큰 토압을 견딜 수 있게 됨으로써 스트럿의 설치 갯 수를 줄일 수 있게 된다.According to the present invention, since the H-beam of the strip is integrally formed by concrete, it is able to withstand greater earth pressure by the rigidity of the H-beam and the concrete, so that the range of application is widened, and the H-beam having a certain standard is formed by the end assembly. Even if a belt length is formed by using, it is possible to appropriately adjust the fixing position of the crimping tool that supports the ends of the belt length to each other. And with the ability to withstand large earth pressures, the number of installation of struts can be reduced.
