Mounting method of steel truss bridge and steel truss bridge
The invention relates to an installation method of a steel truss bridge and the steel truss bridge, and the installation method comprises the following steps: hoisting lower chords of two first sections to an installation site, so that the lower chords of the two first sections are respectively positioned on two sides of the center of a route, and lower node plates are fixed on the lower chords; the lower-layer bridge deck structure of the first section is hoisted to the position between the two lower chord members; hoisting the web member to the lower node plate; the upper chord members of the two first sections are hoisted to the positions above the lower chord members of the two first sections, and upper node plates on the upper chord members are fixed to the web members, so that the two web members and the upper chord members form a triangular structure; the upper-layer bridge deck structure of the first section is hoisted to the position between the two upper chords, and a first section trussed beam is formed; and the steps are repeated, the rest sections of trussed beams are hoisted in sequence, and the steel truss bridge is formed. Due to the fact that the trussed girder structure of the bridge is constructed in a segmented mode, when the segmented trussed girder is constructed, all the rod pieces in the split state can be transported to a construction site to be hoisted through a small girder transporting vehicle.
本发明涉及一种钢桁桥梁的安装方法及钢桁桥梁，其包括以下步骤：将两个首节段的下弦杆吊装至安装场地，使两个首节段的下弦杆分别位于路线中心的两侧，其中，下弦杆上固定有下节点板；将首节段的下层桥面结构吊装至两个下弦杆之间；将腹杆吊装至下节点板；将两个首节段的上弦杆吊装至两个首节段的下弦杆的上方，并将上弦杆上的上节点板与腹杆固定，使两个腹杆与上弦杆形成三角形结构；将首节段的上层桥面结构吊装至两个上弦杆之间，形成首节段桁梁；重复上述步骤，依次吊装剩余节段桁梁，形成钢桁桥梁。由于将桥梁的桁梁结构分节段建造，节段桁梁建造时，利用小型运梁车即可将处于拆分状态的各杆件运输到施工现场进行吊装。
