Large-span simply-supported steel truss bridge structure based on sliding web members and construction method of large-span simply-supported steel truss bridge structure
The invention belongs to the technical field of bridge engineering construction, and provides a large-span simply-supported steel truss bridge structure based on sliding web members and a construction method of the large-span simply-supported steel truss bridge structure. The truss upper mechanism comprises an upper chord member and web members arranged at the two ends of the upper chord member through hinge pieces, and a pulley is arranged at the end, away from the upper chord member, of each web member. The truss lower mechanism comprises a lower chord member and a sliding groove which is formed in the lower chord member and matched with the pulley. Nodes between the upper chord members and the web members are determined in advance in a hinged mode, after the truss upper mechanism and the truss lower mechanism are hoisted, the pulleys on the web members can be placed in the sliding grooves matched with the pulleys in a sliding mode, and through sliding of the pulleys in the sliding grooves, the web members can be fixed. The splicing position of the node between the lower chord member and the web member can be quickly and accurately determined, the operation difficulty is reduced, and the splicing precision of the node between the chord member and the web member is improved.
本发明属于桥梁工程施工技术领域，提出了基于滑动腹杆的大跨度简支钢桁架桥梁结构及其施工方法，包括桁架上部机构和桁架下部机构；其中，所述桁架上部机构包括上弦杆，以及通过铰接件设置在所述上弦杆两端的腹杆，每个腹杆远离所述上弦杆的一端设置有滑轮；所述桁架下部机构包括下弦杆，以及开设在所述下弦杆上的与所述滑轮适配的滑槽；上弦杆与腹杆之间的节点通过铰接方式提前确定，所述架上部机构和所述桁架下部机构被吊装后，所述腹杆上的滑轮可以滑动的放置到与其适配的滑槽中，通过滑轮在滑槽中的滑动，能够快速准确的确定下弦杆与腹杆之间节点的拼接位置，降低了操作难度，提高了弦杆和腹杆间节点的拼接精度。
