Installation method of steel truss girder rod piece
The invention discloses a mounting method of a steel truss girder rod piece, which comprises the following steps of: mounting turnover equipment and lifting equipment between a diagonal web member and a truss bridge section in advance, and driving the diagonal web member to generate certain angle deviation relative to the truss bridge section through the lifting equipment; the method comprises the following steps of: hoisting two adjacent truss bridge sections to avoid interference between the part, extending out of the truss bridge section, of one end of each diagonal web member and the other adjacent truss bridge section, and after the two adjacent truss bridge sections are hoisted to a mounting position and the diagonal web members are released by hoisting equipment, finishing mounting and fixing between the two ends of each diagonal web member and the two truss bridge sections. Therefore, the diagonal web members can be hoisted once along with the truss bridge sections, hoisting operation can be completed on the premise that hoisting interference does not occur, the stability of connection between the truss bridge sections is guaranteed on the premise of the size structure, the assembling and connecting efficiency of the truss bridge sections is improved, additional construction operation platform erecting is avoided, the operation applicability is improved, and the construction cost is reduced. The hoisting difficulty is reduced.
本发明公开了一种钢桁梁杆件的安装方法，通过在斜腹杆与桁架桥节段之间预先安装翻转设备和提升设备，通过提升设备带动斜腹杆相对于桁架桥节段发生一定角度偏移，以规避斜腹杆一端伸出到桁架桥节段外的部分与相邻的另一桁架桥节段之间发生干涉，并在两个相邻的桁架桥节段吊装至安装位之后，提升设备放开斜腹杆之后，完成斜腹杆的两端与两个桁架桥节段之间的安装固定，进而实现斜腹杆跟随桁架桥节段进行一次吊装即可在不发生吊装干涉的前提下完成吊装作业，既保证了该尺寸结构前提下桁架桥节段之间连接的稳定性，又提高桁架桥节段拼装连接效率，避免另外搭设施工作业平台，提高了作业适用性，降低吊装难度。
