부연 하자면, 상기 보조 브라켓(170)은, 수직판(171)을 제작시 일체형 판을 이용하여 중앙을 직사각형으로 절개하여 사용하는 바, 그 수직판(171)을 제작시 양측에 사각판 2개와 중앙의 직사각형 형태로 형성된 연결판 2개를 용접하여 제작하여 사용할 수도 있다.In other words, the auxiliary bracket 170 is used to cut the center in a rectangular shape using an integrated plate when manufacturing the vertical plate 171, two square plates and the center on both sides when the vertical plate 171 is manufactured. It is also possible to produce and use two connecting plates formed in the rectangular shape of.

또한, 상기 보조 브라켓(170)은, 수직판(171)의 길이방향 양측에 각각 2개의 연결 고리(175)가 형성되는 바, 그 연결 고리(175)에 체인(181)(191)을 연결하여 이음부에 대한 용접 작업을 통해 견고한 지지 구조를 구성할 수 있고, 그 체인(181)(191)의 끝에 각각 앵커 볼트(182)와 앵커대(192)를 결합하고 이음부에 대한 용접을 행할 수 있다.In addition, the auxiliary bracket 170, two connecting rings 175 are formed on both sides of the vertical plate 171 in the longitudinal direction, respectively, by connecting the chain 181, 191 to the connecting ring 175 The welding operation on the joint can form a rigid support structure, and the anchor bolts 182 and the anchor bar 192 can be joined to the ends of the chains 181 and 191, respectively, and welded to the joint. have.

또한, 상기 브라켓(160)과 보조 브라켓(170)은, 수평판(163)(173)의 하부에 2개의 지지판(164)(174)이 용접되어 형성되었지만, 필요에 따라 2개 이상의 지지판을 수직판(161)(171)과 수평판(163)(173)과 밀착되도록 용접하여 사용가능하다 할 것이다.In addition, the bracket 160 and the auxiliary bracket 170 are formed by welding two support plates 164 and 174 to the lower portions of the horizontal plates 163 and 173, but may receive two or more support plates as necessary. The direct plates 161 and 171 and the horizontal plates 163 and 173 will be able to be used by welding in close contact.

상술한 본 발명의 구성에 따른 효과를 설명한다.The effect by the structure of this invention mentioned above is demonstrated.

본 발명은, 브라켓의 하부에 별도의 보조 브라켓을 설치하는 바, 브라켓의 상부에 유압 잭이 안착되어 빔을 상부로 인상하고 교좌 장치에 대한 유지보수 작업을 진행하는 경우에도 견고한 지지력을 제공할 수 있는 효과를 얻을 수 있다.According to the present invention, a separate auxiliary bracket is installed at the bottom of the bracket, and a hydraulic jack is mounted on the upper portion of the bracket to raise the beam to the upper side and provide solid support even when performing maintenance work on the chair device. You can get the effect.

즉, 브라켓의 하부를 지지하는 보조 브라켓은 길이방향 양측에 각각 연결 부재1,2가 설치되어 앵커 볼트와 앵커대가 체결되어 너트로 고정되는 바, 하부에서 견고한 지지력을 제공할 수 있게 되는 것이다.That is, the auxiliary bracket supporting the lower part of the bracket is provided with connecting members 1 and 2 on both sides in the longitudinal direction, so that the anchor bolt and the anchor rod are fastened to be fixed by a nut, thereby providing a firm supporting force at the lower part.
