Steel box truss type arch truss segment and support-free assembling and erecting method thereof
The invention discloses a steel box truss type arch truss segment and a support-free assembling and erecting method thereof, and belongs to the technical field of arch bridge construction. The arch truss segment comprises two groups of arch truss sheet sections, each arch truss sheet section comprises an upper chord member and a lower chord member, the upper chord members and the lower chord members are fixedly connected through web members, and temporary mounting devices are arranged at the end parts of the upper chord members and the lower chord members; and the middle connecting system, theupper plane connecting system and the lower plane connecting system are fixedly connected between the two groups of arch truss piece sections. During erection, the cable crane lifts the lifting appliance to a set elevation to mount the arch truss piece sections to be erected on the erected arch truss piece sections through the temporary mounting devices; fastening cables are hung on the arch truss segments to be erected and are tensioned in a grading manner, a cable crane is transversely moved into the bridge to hoist the middle connecting system and connect the middle connecting system between the upstream arch truss segment frame and the downstream arch truss segment frame, and finally the upper plane connecting system and the lower plane connecting system are assembled by using the cable crane to form the arch truss segment. The arch bridge is assembled and erected without a support, and the construction efficiency of the arch bridge is improved.
本发明公开了一种钢箱桁架式拱桁节段及其无支架拼装架设方法，属于拱桥施工技术领域，拱桁节段包括拱桁片节段，拱桁片节段设有两组，拱桁片节段包括上弦杆和下弦杆，在上弦杆和下弦杆之间通过腹杆固定连接，上弦杆和下弦杆的端部均设有临时安装装置；中间连接系、上、下平面连接系固定连接在两组拱桁片节段之间。架设时，缆索吊机提升吊具至设定高程；将待架的拱桁片节段通过临时安装装置安装在已架的拱桁片节段上；在待架的拱桁片节段上挂设扣索并分级张拉，缆索吊机横移至桥中吊装中间连接系并将其连接在上下游拱桁片节段架之间，最后用缆索吊机拼装上、下平面连接系，形成拱桁节段。本发明实现了无支架拼装架设拱桥，提高了拱桥施工效率。
