Large-span assembly type steel bridge structure
The invention relates to the technical field of bridge construction, in particular to a large-span fabricated steel bridge structure which comprises a bridge body, first guardrails are installed on the two sides of the bridge body, the bridge body is slidably connected with mounting frames, and the sliding direction of the mounting frames relative to the bridge body is inclined or perpendicular to the two side faces of the bridge body. Adjusting units used for adjusting the sliding resistance of the mounting frames relative to the bridge body are installed at the sliding connection positions of the bridge body and the mounting frames, supporting frames are installed on the mounting frames below the first guardrails, second guardrails are installed on the mounting frames on one sides of the supporting frames, and the second guardrails are located on the sides, away from the bridge body, of the first guardrails. The height of each second guardrail is larger than that of the first guardrail, a support is connected between any two adjacent second guardrails in a sliding mode, rollers are rotationally connected to the supports and the second guardrails, and the guardrail can well block vehicles and prevent the vehicles from falling into a bridge.
本发明涉及桥梁施工技术领域，具体为一种大跨径装配式钢桥结构，包括桥体，所述桥体两侧安装第一护栏，所述桥体滑动连接安装架，各所述安装架相对桥体的滑动方向与桥体两侧面倾斜或垂直，所述桥体与安装架的滑动连接处安装用于调节安装架相对桥体的滑动阻力大小的调节单元，各所述安装架在第一护栏下方安装支撑架，各所述安装架在支撑架一侧处安装第二护栏，各所述第二护栏位于第一护栏上远离桥体的一侧处，且各所述第二护栏的高度大于第一护栏的高度，各所述第二护栏任一相邻的两个之间滑动连接支架，各所述支架和第二护栏上转动连接滚筒，本发明使得护栏对车辆进行良好阻挡，防止落入桥下。
