Fabricated connecting joint of steel truss bridge

HU CHEN / LI HUAQIANG

The invention relates to a fabricated connecting joint of a steel truss bridge. An adjusting mechanism is arranged in a bridge bottom adjusting chamber, a positioning plate is slidably connected into a bridge top positioning chamber, first trapezoidal plates are symmetrically and fixedly connected with the top, slidably connected with a contact plate, in a control chamber, the end, fixedly connected with a first spring, of the top of the contact plate is fixedly connected with the inner wall of the top of the control chamber, the inclined faces of second trapezoidal plates on the inner wall of the control chamber on the top of the bridge match the inclined faces of the first trapezoidal plates, movable plates are arranged in two movable pipes which are symmetrically and fixedly installed on the inner wall of the bottom of the control chamber, the tops of the two movable plates are both fixedly connected with the bottom of the contact plate, control mechanisms are symmetrically arranged on the inner wall of the bottom of the control chamber, and the top of a connecting beam top extension rod penetrates through a bridge top extension pipe and extends into the control chamber to make movable contact with the bottom of the contact plate. According to the invention, the extension rod is inserted into the extension pipe, the effect of improving the stability of the connecting beam is achieved while mounting and fixing are convenient.

本发明涉及一种钢桁架桥梁装配式连接节点，桥梁底部调节室内设有调节机构，桥梁顶部定位室内滑动连接有定位板，控制室内滑动连接接触板的顶部对称固定连接有一号梯形板，接触板顶部固定连接一号弹簧的一端与控制室的顶部内壁固定连接，桥梁顶部控制室内壁二号梯形板的斜面与一号梯形板的斜面相适配，控制室的底部内壁对称固定安装两个活动管内均滑动连接有活动板，两个活动板的顶部均与接触板的底部固定连接，控制室的底部内壁对称设有控制机构，连接梁顶部延伸杆的顶部贯穿桥梁顶部延伸管并延伸至控制室内与接触板的底部活动接触，本发明通过将延伸杆插入延伸管内，实现方便进行安装固定的同时，增加连接梁稳定性的效果。
