Steel truss girder segment and mounting method thereof
The invention relates to the technical field of bridge construction, in particular to a steel truss girder segment and a mounting method thereof. The steel truss girder segment comprises two upper chord sets and two lower chord sets, each upper chord set comprises two upper chords, and each lower chord set comprises two lower chords; and one or more vertical web rods are arranged between the upperchord and the lower chord on each side, the two ends of the vertical web rods are connected with the upper chords and the lower chords respectively, the vertical web rods divide the upper chords andthe lower chords into first cantilevers and second cantilevers, and the length of the first cantilevers is larger than that of the second cantilevers. During erecting, a girder erection crane is driven to the vertical web rod on the outermost side of the erected steel truss girder segment, the length of the second cantilevers is shortened, the extending distance of the girder erection crane is increased, the length of the cantilever of the girder erection crane can be reduced, the girder erection crane is lighter, and the weight of the girder erection crane is reduced. The problem that when anexisting steel truss girder segment is erected, a huge girder erection crane is needed, thus a heavier and stronger steel truss girder segment is needed, and vicious circle is caused can be solved.
本发明涉及桥梁建设技术领域，具体涉及一种钢桁梁节段及其安装方法。该钢桁梁节段，包括：两组上弦杆组和下弦杆组，上弦杆组包括两根上弦杆，下弦杆组包括两根下弦杆；还包括每一侧上弦杆和下弦杆之间至少设有一根竖腹杆，其两端分别连接上弦杆和下弦杆，竖腹杆将上弦杆和下弦杆划分出第一悬臂和第二悬臂，且第一悬臂的长度大于第二悬臂的长度。架设时使架梁吊机行驶至已架设的钢桁梁节段最外侧的竖腹杆处，使第二悬臂的长度变短，使架梁吊机的伸出距离变长，可将架梁吊机悬臂长度减小，使得架梁吊机更加轻便，减少自身重量。可解决在架设现有的钢桁梁节段时，需要庞大的架梁吊机，因此需要更重更强的钢桁梁节段，造成恶性循环的问题。
