Abstract

The invention belongs to the technical field of civil engineering, and discloses an assembled outer sleeve staggered flange intersecting joint, which includes a lower outer sleeve and an upper outer sleeve, and a main body with two ends of the lower outer sleeve and the upper outer sleeve plugged together. The chord, the lower chord installed on the side of the lower outer sleeve and the upper outer sleeve, and the vertical rods and diagonal rods arranged on the side surface of the upper outer sleeve, between the main chord and the lower outer sleeve and the main chord Both the rod and the upper outer sleeve are fixed by the first connection assembly, and high-strength bolts for connecting plates are fixedly installed between the lower outer sleeve and the upper outer sleeve; Using technologies such as outer sleeve, staggered flange and full bolt connection, a prefabricated truss connection intersecting joint suitable for large-span space truss structures is proposed. This joint has high rigidity, good stability, and good mechanical properties. Fully bolted and efficient assembly of space truss structures.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to an assembled outer sleeve staggered flange intersecting joint and a construction method thereof. Background technique [0002] Long-span ring trusses are often used as support structures for long-span spatial structures such as cable dome structures, suspension dome structures, and cable-net structures. , Welded connections at the construction site, in which the intersecting nodes of the ring truss are all welded connections. On-site welding has the problems of many nodes and many weldings, which lead to difficult construction and high cost. At the same time, it is difficult to guarantee the quality of on-site welding, and the stress concentration at the welding place leads to poor durability and poor structural disassembly performance. Contents of the invention [0003] The purpose of the present invention is to provide an assembled outer sleeve staggere...
