Description

강결형 강관버팀보와 중간말뚝 연결구조{A tight connection between steel pipe strut and center pile}A tight connection between steel pipe strut and center pile}

본 발명은 가설 굴착 흙막이벽에서 버팀보와 중간말뚝을 연결하는 연결구조에 관한 것으로서, 보다 상세하게는 강관 버팀보와 중간말뚝을 연결시키기 위하여 ㄷ형강이나 H형강 위에 강관과 곡률이 같은 지지대를 볼트로 연결하고 그 위에 강관 버팀보를 올려놓고 강판을 절곡하여 제작한 강판덮개를 씌워 강결함으로써 유격을 최소화하는 강결형 강관버팀보와 중간말뚝 연결구조를 제공하고자 한다. The present invention relates to a connection structure for connecting the brace and the middle pile in the temporary excavation earthen wall, more specifically, to connect the steel pipe and the support of the same curvature on the c-beam or H-beam with bolts to connect the steel pipe brace and the middle pile The steel pipe brace is placed on it, and the steel plate cover is made by bending the steel plate, and the steel plate is stiffened.

건설현장에서 지하에 건물의 기초, 지하실 또는 콘크리트 벽체를 축조하기 위하여 해당 지반을 굴토한 후, 굴토면이 토압에 의해 붕괴되는 것을 방지하기 위하여 흙막이 공사를 하게 된다.At the construction site, the ground is excavated to build the foundation, basement, or concrete wall in the basement, and then the earthen block is constructed to prevent the earth surface from collapse by earth pressure.

이러한 흙막이는 소정 간격으로 지반에 설치되는 H파일에 굴토면을 받치는 토류벽을 형성하고 H파일의 일측면에 상하로 일정 간격을 가지면서 수평되게 복수의 띠장이 설치되며, 서로 마주보는 띠장과 띠장 사이에 일정간격으로 수평되게 버 팀보가 설치된다.These mudguards are formed in the earth wall to support the pit soil surface in the H pile installed on the ground at predetermined intervals, and a plurality of bands are horizontally installed at regular intervals up and down on one side of the H pile, between the bands and the bands facing each other. Vertibo is installed horizontally at regular intervals.

이때, H파일 사이가 먼 경우에는 버팀보와 버팀보가 수평으로 연결되어 버팀보의 길이가 연장된다.At this time, when the H file is far apart, the brace and the brace is horizontally connected to extend the length of the brace.

그런데, 종래에는 버팀보로 H형강을 사용하고 H형강 버팀보의 연결시 H형강 버팀보에 기초판이나 이음판을 직접 용접하므로 체결이 불편하고 이음구조와 버팀보의 재활용에 문제가 있었다.However, in the related art, H-shaped steel is used as a brace, and when the H-beam brace is connected, the base plate or the joint plate is directly welded to the H-beam brace, so that the fastening is inconvenient and there is a problem in recycling the joint structure and the brace.

도 1은 종래의 강관 버팀보와 중간말뚝 연결부를 나타내는 도면이다. 1 is a view showing a conventional steel pipe brace and the intermediate pile connection.

종래의 강관 버팀보에서는 절곡된 U볼트를 이용하여 중간말뚝과 연결된 ㄷ형강이나 H형강에 볼트 연결하는데, 종래의 강관 버팀보와 중간말뚝 연결부 도면을 참조하면, 이는 2개의 U볼트만으로 접합되는 형식이므로 연결부에서 유격이 발생할 수 있으며, 버팀보에 예상치 못한 하중이 작용할 경우에 부분적으로 손상될 수 있는 문제점이 발생하였다. Conventional steel pipe braces are bolted to the c-beams or H-beams connected to the intermediate piles using bent U bolts. Referring to the drawings of the conventional steel pipe braces and the intermediate piles, these are connected to only two U bolts. There is a problem in that the play may occur, and it may be partially damaged when an unexpected load is applied to the brace.

본 발명에서는 강관 버팀보와 중간말뚝을 연결시키기 위하여 ㄷ형강이나 H형강 위에 강관과 곡률이 같은 지지대를 볼트로 연결하고, 그 위에 강관 버팀보를 올려놓고 강판을 절곡하여 제작한 덮개를 씌워 강결함으로써 유격을 최소화하고자 하는 목적이 있다. In the present invention, to connect the steel pipe brace and the middle pile by connecting the support of the same curvature with the steel pipe on the c-beam or H-beam with bolts, put the steel pipe brace on the cover and bending the steel plate to cover the steel plate The aim is to minimize this.

상기와 같은 목적을 달성하기 위한 기술적인 구성으로서 본 발명은, 강관버팀보와 중간말뚝 연결부에 있어서 ㄷ형강이나 H형강 위에 지지대를 설치하고 지지대 위에 강관 버팀보를 올려 놓고 강판덮개를 씌우는 형태의 강관버팀보와 중간말뚝 연결부를 포함하여 구성되는 것을 특징으로 한다. As a technical configuration for achieving the above object, the present invention, in the steel pipe brace and the middle pile connection portion, the support is installed on the c-beam or H-beam and put the steel pipe brace on the support and the steel pipe brace in the form of a steel plate cover Characterized in that it comprises a middle pile connection.

본 발명에 따르면, 강관버팀보와 중간말뚝 연결부를 통하여 버팀보의 시공 중 중간말뚝과의 연결부에서 유격을 최소화하여 전체적인 가설 버팀보 시스템의 안정성을 확보하고 예상치 못한 하중이 작용한 경우에도 손상을 방지할 수 있는 효과가 있다. According to the present invention, by securing the stability of the overall hypothesis support system by minimizing the play at the connection with the intermediate pile during the construction of the support through the steel pipe support and the intermediate pile connection and prevent damage even when an unexpected load is applied It works.

이하, 첨부된 도면에 따라 본 발명인 강결형 강관버팀보와 중간말뚝 연결구조에 대하여 설명한다. Hereinafter, with reference to the accompanying drawings, the present invention will be described for the steel-type steel pipe support and the intermediate pile connection structure.

도 2는 강결형 강관 버팀보와 중간말뚝 연결구조를 나타내는 도면이다. Figure 2 is a view showing the structure of the steel pipe brace and the intermediate pile connection.

상기 도 2에 도시된 바와 같이, ㄷ형강이나 H형강 위에 강관과 곡률이 같은 지지대(10)를 볼트 접합한 후 그 위에 강관 버팀보(20)를 설치하고 강판덮개(30)를 씌운 후 상기 강판덮개(30)와 상기 지지대(10)를 볼트 부재(55)로 연결하는 강결형 강관버팀보와 중간말뚝 연결부이다. As shown in FIG. 2, the bolt 10 is the same curvature 10 as the steel pipe on the c-shaped steel or the H-shaped steel, and then a steel pipe brace 20 is installed thereon and the steel plate cover 30 is covered with the steel plate. The 30 and the support 10 is a rigid steel pipe support and intermediate pile connecting portion connecting the bolt member 55.
