본 발명은 건축물의 기초 공사용 가시설 토류벽 패널에 관한 것으로서, 특히 흙막이용 토류벽 패널을 접힘식으로 구성하여 패널에 대한 해체시 체결구만 후방으로 밀어 패널 해체가 간단하도록 하고, 그로 인해 시공성 향상 및 지반의 안정성을 확보할 수 있도록 하는 건축물의 기초 공사용 가시설 토류벽 패널 설치 구조에 관한 것이다.The present invention relates to a temporary earth wall panel for a foundation construction of a building, and in particular, the earth wall panel for folding the earthquake is constructed by folding only the fastener to the rear when dismantling the panel to simplify the dismantling of the panel, thereby improving workability and ground stability It is about temporary facility earth wall panel setting structure for the foundation construction of building to enable to secure.

일반적으로 터파기 등과 같은 기초 공사를 하는 경우, 측면에 다수개의 에이치 파일을 설치하고, 그 에이치 파일의 사이에 직사각형 형태의 목재로 제작된 토류벽 패널을 설치하여 가시설 구조를 구성하게 된다.In general, in the case of foundation work, such as a trench, a plurality of H piles are installed on the side, and earth wall panels made of rectangular wood are installed between the H piles to form a temporary structure.

상기 가시설, 즉 토류벽은 '절토 및 성토의 측면을 지지하기 위한 벽'으로, 주변 지반의 붕괴를 방지함과 아울러, 지하 공사중 발생될 수 있는 붕괴 사고를 미연에 방지하기 위해 설치된다.The temporary facility, ie, the earth wall, is a wall for supporting the sides of the cut and fill, and is installed to prevent the collapse of the surrounding ground and to prevent the collapse of the ground.

도 1은 기존 건축물의 기초 공사용 가시설 토류벽을 나타내는 도면으로서, 기초 공사를 위해 에이치 파일(10)이 다수개 지반에 입설되고, 내부 터파기를 시행한 후 그 에이치 파일(10)의 사이에 다수개의 토류벽 패널(30)이 설치된다.1 is a view showing the temporary earth wall of the temporary construction of the existing building, a number of H pile (10) is installed in a plurality of grounds for the foundation work, after the internal trench is carried out a plurality of earth walls between the H pile (10) The panel 30 is installed.

상술한 구성에서 알 수 있는 바와 같이, 상기 에이치 파일(10)에 결합된 토류벽 패널(30)에 대한 해체 작업은, 하부 토류벽 패널(30)의 빗금친 부분에 대한 토사를 굴착하여 토류벽 패널(30)을 사선으로 외부로 빼내는 방법으로 해체하게 된다.As can be seen in the above-described configuration, the dismantling operation of the earth wall panel 30 coupled to the H pile 10, excavates the soil on the hatched portion of the lower earth wall panel 30 to excavate the earth wall panel 30. ) Is disassembled by pulling it outward with a diagonal line.

그러나, 상기 하부 토류벽 패널(30)이 설치된 지역의 지질이 사질 등으로 형성된 경우, 하부 굴착후 상부에서 흙이 밀려내려오는 문제점이 있어, 토류벽 패널(30)에 대한 해체 작업이 어려울뿐 만 아니라, 토류벽 패널을 해체한 경우 토목 공사를 한 그 측면의 지반이 침하되는 등 지반 붕괴의 위험을 내포하고 있는 실정이다.However, when the geology of the area where the lower earth wall panel 30 is installed is formed of sand, etc., there is a problem that the soil is pushed down from the upper part after the lower excavation, so that the dismantling work for the earth wall panel 30 is not only difficult, If the earth wall panel is dismantled, the ground on the side of the groundwork is subsided, which implies the risk of ground collapse.

특히, 상기 가시설에 대한 해체 작업에 따른 지반 붕괴로 인하여 매년 인명 및 재산 손실이 발생되고 있는 실정이다.In particular, due to the ground collapse due to the dismantling work for the temporary facility, the loss of life and property is generated every year.

본 발명은 상술한 문제점을 감안하여, 본 발명은, 흙막이용 토류벽 패널을 접힘식으로 구성하여 패널에 대한 해체 작업시 체결구만 후방으로 밀면 패널이 해체될 수 있도록 함으로, 시공성 향상 및 토사의 굴착이 없는 관계로 지반의 안정성 확보를 할 수 있도록 하여 인명 및 재산 손실을 방지할 수 있도록 하는 건축물의 기초 공사용 가시설 토류벽 패널 설치 구조를 제공함을 그 목적으로 한다.The present invention in view of the above problems, the present invention, by constructing the earth wall panel for earthquake folding type so that the panel can be dismantled only when the fastener is pushed to the rear during the dismantling work for the panel, the workability is improved and the excavation of earth and sand The purpose is to provide a temporary structure earth wall panel installation structure for the basic construction of a building that can ensure the stability of the ground without any loss of life and property.

본 발명은 상술한 목적 달성을 위해, 본 발명은, 에이치 파일과 토류벽 패널을 포함하는 건축물의 기초 공사용 가시설에 있어서, 상기 토류벽 패널(600)은 접힘 작동되도록 4개로 분절된 토류벽 몸체(200)(200')(200")의 전,후방에 각각 경첩(230)에 의해 중앙분절부분과 양측분절부분에서 연결됨과 아울러, 전방의 체결틀에 체결구가 결합되어 일자형 형태로 유지되며, 한편 상기 토류벽 패널이 다수개 에이치 파일의 사이에 설치되어 가시설 구조를 구성함을 특징으로 하는 건축물의 기초 공사용 가시설 토류벽 패널 설치 구조를 제공한다.The present invention, in order to achieve the above object, the present invention, in the temporary construction of the building including an H pile and the earth wall panel, the earth wall panel 600 is divided into four earth wall body 200 to be folded operation ( The front and rear of the 200 ') and 200 ", respectively, are connected at the center segment and both side segments by hinges 230, and the fastener is coupled to the front fastening frame to maintain a straight shape. Provided is a temporary earth wall panel installation structure for the basic construction of the building, characterized in that the panel is installed between a plurality of H pile to form a temporary structure.

이하, 첨부 도면을 참조하여 본 발명의 실시예를 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명의 건축물의 기초 공사용 가시설 토류벽 패널의 사시도로서, 지반에는 다수개의 에이치 파일(100)이 입설되고 그 에이치 파일(100)의 사이에 지반의 붕괴를 방지하기 위한 흙막이용 가시설(800)이 설치된다.FIG. 2 is a perspective view of a temporary earth wall panel for temporary construction of a building according to the present invention, in which a plurality of H piles 100 are installed in the ground, and a temporary blocking facility 800 for preventing soil collapse between the H piles 100 is shown. ) Is installed.
