Bearing wall structure

본 고안은 도로공사시 도로주변에 설치되어 공사때 발생되는 낙석과 파편의 비산을 방지하기 위하여 설치되는 흙막이 벽에 관한 것으로, 종래의 흙막이 벽은 기둥으로 사용되는 H빔을 일정간격으로 세운후 그 사이에 사각각목을 적층하여 흙막이 벽을 구성하고, H빔 사이에 적층된 각목을 고정하기 위해 끼움목(쐐기)을 끼움으로 인하여, 작업시간 및 인력이 많이 소요되며, 외관이 미려하지 못한 단점이 있었다. 그러나 본 고안에 있어서는 H빔에 사각각목을 삽치하는 대신 표면을 굴곡시켜 보강시킨 굴곡철판(라이너 플레이트)를 삽치함으로 인하여 외관 및 벽체로서의 지지력을 보강하였으며, H빔에 굴곡철판을 삽치하는 방법도 하나씩 낱개로 삽치하는 것이 아니라 높이에 따라서 복수의 굴곡철판을 볼트와 너트를 이용하여 수직으로 적층되게 조립한 후, 이 조립체를 한번에 H빔에 삽치토록 한 것이며, 굴곡철판을 H빔에 밀착 고정시킴에 있어서도 적층된 굴곡철판의 측변에 길이 방향으로 길게 각강관을 부착한 다음, 각강관과 H빔 사이에 스크류 잭을 끼워넣고, 스크류(나사) 길이를 조정하여 밀착력을 얻도록 한 것이다. 이상과 같은 본고안 구조로 흙막이 벽을 구성하게 되면 작업이 아주 간편하고 편리하게 되어 작업시간 및 인력을 상당히 감축할 수 있게 되는 것이며, 또한 외관을 미려하게 할 수 있어 그 효율성을 증대시킨 아주 유용한 고안인 것이다.

A combination system and a method of controlling the same are implemented so that a user can more conveniently use a user setting menu such as an environment setting. In the DVDP / VCR combination system of the present invention, when a command for displaying the environment setting menu for the VCR unit is input through the input unit in the state of outputting the image reproduction signal through the dedicated output terminal of the DVDP unit, the VCR control unit outputs the image reproduction signal to the DVDP unit. A command signal is output to the DVD controller so as to output a message according to the output of the dedicated output terminal. In response to this command, the DVD control unit reads a message according to the dedicated output state of the video reproduction signal and controls the DVDP unit to output a message through the dedicated output terminal. Accordingly, the user can recognize that the DVD image reproduction signal of the DVDP unit is in the output state of the dedicated output terminal, so that subsequent operations for setting the environment of the VCR unit can be performed.

본 발명은 낙석방지용 안전망에 관한 것으로, 1단계로 암반의 하단부를 제외한 전체의 가장자리에 일정한 간격으로 앵커볼트를 고정한 다음 앵커볼트의 고리부를 통과하는 로우프를 설치 고정하는 단계: 2단계로 앵커볼트에 고정되어 있는 와이어의 상부에 안전망을 올려놓고 고정하는 단계: 3단계로 앵커볼트에 종형 와이어를 설치한 다음 와이어를 사선방향으로 향하게 하되 그 일측의 와이어와 접하는 부분에 안전망과 함께 결착클립으로 고정한 다음 와이어를 다시 반대의 사선방향으로 향하게 하여 다른 와이어와 접하는 부분에 결착클립으로 고정하는 단계: 4단계로 종방향의 와이어를 하단의 앵커볼트에 연결되어 있는 와이어와 결속하여 고정하는 단계로 이루어진 것으로서, 구조가 간단하여 제작이 용이하고 와이어가 사선형으로 형성되어 있기 때문에 낙석발생시 와이어가 암반에 고정된 것이 아니기 때문에 최대의 탄력성을 얻을 수가 있으며, 또한 암반의 내부에 별도의 앵커볼트가 없음으로서 낙석발생시 낙석이 막힘 없이 하단으로 잘 흐를 수가 있으며, 안전망이나 와이어가 파손되었을 경우 결착클립만 분리하므로서 다른 와이어들은 설치된 상태를 유지할 수 있는 것으로서 수명의 연장과 유지보수의 편리성을 기할 수 있는 유용한 발명인 것이다. The present invention relates to a safety net for rockfall prevention, the first step of fixing the anchor bolts at regular intervals to the entire edge except the lower end of the rock and then installing and fixing the rope passing through the ring portion of the anchor bolt: to the anchor bolt in two steps Put the safety net on the upper part of the fixed wire and fix it: In step 3, install the vertical wire on the anchor bolt, and then point the wire diagonally, and fix it with the safety net together with the safety net at the part contacting the wire on one side. Fastening the wire back to the opposite diagonal direction and fastening it with a fastening clip in contact with the other wire: the step 4 consists of fastening the wire in the longitudinal direction with the wire connected to the anchor bolt at the bottom, Simple structure makes it easy to manufacture and wire is formed in diagonal shape. Therefore, when the rockfall occurs, the wire is not fixed to the rock, so maximum elasticity can be obtained, and since there is no separate anchor bolt inside the rock, the rockfall can flow well to the bottom without clogging, and the safety net or the wire is broken. If it is, it is a useful invention that can separate the binding clip to maintain the installed state of the other wires to extend the life and convenience of maintenance.

Wire rope seperating and fixing device of picket fence for preventing road falling rock

본 고안은 도로낙석 방지책의 와이어로프 분리고정장치에 관한 것이다. 종래에는 와이어로프가 도로를 따라 일정간격을 두고 형성되는 지주에 분리됨이 없이 연속적으로 이어지는 식으로 고정 및 설치되어 있어, 구간별 부분파손 및 손상시 전구간에 걸쳐 하자보수 및 교체가 이루어져야만 되므로 비효율적일 뿐만 아니라 시공이 번거롭고 불편하고, 또한 이로 인해 막대한 비용손실을 초래하는 문제점이 있었다. The present invention relates to a wire rope separation fixing device of the road fall prevention measures. Conventionally, the wire rope is fixed and installed in a continuous manner without being separated from the shore formed at a predetermined interval along the road, and in case of partial breakage and damage by section, defect repair and replacement must be performed throughout the entire area, which would be inefficient. Not only the construction is cumbersome and inconvenient, but also caused a huge cost loss. 따라서 본 고안은 중간부에 상호 대향되게 각각 와이어삽입홈(41A)(42A)이 형성된 제1몸체(41) 및 제2몸체(42)로 분리 구성되어 스크류(44) 체결에 의해서 지주(1)에 고정되는 와이어고정구(4)가 구비됨에 있어서, 상기 제2몸체(42)의 와이어삽입홈(41A)(42A) 양측으로 와이어인출구(45)(45A)를 형성하고, 상기 와이어인출구(45)(45A)를 통해 각각 인출된 와이어로프(3)를 고정밴드(5)로 고정함으로써 방책의 부분파손 및 손상시 구간별 부분보수 및 교체가 가능할 뿐만 아니라 작업의 효율성 및 간편성을 기할 수 있고, 막대한 유지보수비의 절감효과를 가져오는 이점이 있다. Therefore, the present invention is divided into a first body 41 and a second body 42 each having wire insertion grooves 41A and 42A formed to face each other in an intermediate portion, and the support 1 is formed by fastening the screw 44. In the wire fixing tool 4 is fixed to the wire inlet, 41A, 42A of wire insertion grooves 41A and 42A of the second body 42 are formed on the wire outlets 45 and 45A, and the wire outlet 45 is formed. By fixing the wire ropes 3 drawn out through the 45A with the fixing bands 5, not only can the parts be repaired and replaced by sections in case of partial breakage or damage of the measures, but also the efficiency and simplicity of the work can be enormous. This has the advantage of reducing the maintenance cost.
