본 발명은 버팀보 조인트에 관한 것으로, 더욱 상세하게는 버팀보들을 연결하여 사용할 때 상기 버팀보들에 구멍을 천공하지 않고 견고하게 연결할 수 있도록 한 버팀보 조인트에 관한 것이다.The present invention relates to a reinforcement joint, and more particularly, to a reinforcement joint that can be connected firmly without drilling a hole in the reinforcement when used in connection with the reinforcement.

통상 기존의 지하철 공사나 건물의 지하층을 만들기 위하여 터파기를 하는 경우의 시공방법은, 우선 계획된 평면을 따라 설계 깊이까지 구멍을 뚫고, 수직파일을 설치한다. 수직파일의 설치가 끝나면, 부분적으로 굴착을 하고, 주형보와 복공판을 설치한다. 복공판의 설치가 끝나면 이후의 공사는 굴착작업과 굴착에 따른 버팀보의 설치가 반복되면서 공사가 진행된다. 따라서 이러한 가시설을 설계하기 위하여 굴착 단계별 토압과 버팀보에 작용하는 하중을 반복 계산하여, 최대값을 견딜 수 있도록 버팀보를 설치한다. In general, the construction method in the case of digging in order to make a basement of an existing subway construction or a building, first drills a hole along the planned plane to the design depth, and installs a vertical pile. After the installation of the vertical pile, the excavation is partially carried out and the mold beam and the perforated plate are installed. After the installation of the perforated plate is completed, the subsequent construction is carried out by repeating the excavation work and the installation of the brace according to the excavation. Therefore, in order to design such a temporary facility, it is necessary to repeatedly calculate the earth pressure and load applied to the brace in the excavation stage and install the brace to endure the maximum value.

이처럼, 현재 건축 및 토목 공사의 지하 굴착공사에서 굴착에 따른 지반의 붕괴를 방지하기 위하여 버팀보를 사용하는 굴착공법이 많이 사용되고 있으며, 그 중 일례로 도 1에서처럼, 지반을 굴착하기 전에 먼저 흙막이벽(1)을 설치하고, 지반을 굴착한 다음 흙막이벽(1)의 내측면에 띠장(2)과 버팀보(3)를 설치하여 지반의 붕괴를 방지하고 있다. 버팀보(3)에는 굴착에 따라 발생하는 토압에 의해 축력이 작용하고, 이 축력에 의해 버팀보(3)는 압축 변형이 발생하며, 이 압축 변형에 의해 흙막이벽(1)이 굴착부 방향으로 휘게 되는데, 이 휨 변형량을 줄이기 위하여 상 기 버팀보(3)와 띠장(2)의 사이에는 서포트(4)(예컨대, 실린더식 하중잭)이 설치되기도 한다.As such, in the underground excavation work of construction and civil engineering, a digging method using a brace is widely used to prevent the collapse of the ground due to the excavation, and as an example, as shown in FIG. 1) is installed, and the ground is excavated, and then the band 2 and the brace 3 are installed on the inner surface of the retaining wall 1 to prevent the ground from collapsing. The axial force acts on the brace 3 by the earth pressure generated by the excavation, and by this axial force the compressive deformation of the brace 3 occurs, and the retaining wall 1 is bent in the direction of the excavation by this compressive deformation. In order to reduce the amount of deflection, the support 4 (eg, a cylindrical load jack) may be provided between the support 3 and the belt 2.

버팀보(3)는 대개 H형강을 이용하게 되며, 필요한 경우 다수개가 연결되어 사용된다. The braces (3) usually use H-beams, and if necessary, a plurality of them are connected and used.

종래 기술에 의한 버팀보(3)의 조인트조는 다음과 같다.Joint group of the brace 3 according to the prior art is as follows.

도 2에서처럼, 이웃하는 버팀보(3-1,3-2)의 마주하는 단부에 각각 이음판(5,6)을 용접으로 결합하여, 이음판(5,6)을 체결구(7)(볼트와 너트) 결합함으로써 버팀보(3-1,3-2)들을 결합한다. 그리고, 버팀보(3-1,3-2)들의 상하부에 버팀보(3-1,3-2)의 이음부를 덮는 보강판(8)을 각각 덧대어 체결구(8a)(볼트와 너트)를 결합하여 버팀보(3-1,3-2)들을 연결한다.As shown in Fig. 2, the joint plates 5 and 6 are welded to the opposite ends of neighboring braces 3-1 and 3-2, respectively, so that the joint plates 5 and 6 are fastened to the fastener 7 (bolts). And nut) to couple the props 3-1 and 3-2. Then, the upper and lower parts of the braces 3-1 and 3-2 are padded with reinforcing plates 8 covering the joints of the braces 3-1 and 3-2, respectively, to engage the fasteners 8a (bolts and nuts). Connect the braces (3-1,3-2).

그러나, 종래 기술에 의한 버팀보 조인트조에 의하면 다음과 같은 문제점이 있다.However, according to the conventional joint joint group, there are the following problems.

버팀보(3-1,3-2)들의 연결을 위한 이음판(5,6) 및 보강판(8)을 체결구(7,9)로 체결하므로 작업이 번거롭고 불편하며, 인건비가 많이 소요된다.The joints (5, 6) and the reinforcing plate (8) for the connection of the braces (3-1, 3-2) is fastened with fasteners (7, 9), which is cumbersome and inconvenient, and labor costs are high.

그리고, 보강판(8)의 결합을 위하여 버팀보(3-1,3-2)에 볼트공을 천공함에 따라 버팀보(3-1,3-2)의 내력 손실이 발생된다. 이처럼 볼트공이 천공된 버팀보(3-1,3-2)를 재사용하는 경우, 버팀보(3-1,3-2)에 천공된 볼트공으로 인한 버팀보(3-1,3-2)의 내력이 손실 때문에 재사용하기 어렵게 된다. 아울러, 볼트 이음의 경우, 다수개의 볼트공을 천공하는데 많은 시간이 소요되며, 그에 따라 작업시간이 지연되고 볼트의 체결 및 해체에 많은 인력과 시간이 소요된다는 단점이 있다.Then, as the bolt holes are drilled in the bracing beams 3-1 and 3-2 for the coupling of the reinforcing plate 8, the strength loss of the bracing beams 3-1 and 3-2 is generated. When reusing the bolted holes (3-1,3-2) in this way, the strength of the bolts (3-1,3-2) due to the bolt holes punched in the braces (3-1,3-2) is lost This makes it difficult to reuse. In addition, in the case of bolted joint, it takes a lot of time to drill a plurality of bolt holes, there is a disadvantage that the work time is delayed and a lot of manpower and time is required to fasten and dismantle the bolt.

이와 같은 문제점을 해결하기 위하여 특허 제581610호, 특허 제641662호로 등록된 버팀보 조인트조가 있다.In order to solve such a problem, there is a support joint group registered in Patent No. 581610 and Patent No. 641662.
