Description

Assembled compression bar structure suitable for vertical rotation of bridge Technical Field The invention relates to the technical field of assembly type buildings, in particular to an assembly type compression bar structure suitable for a vertical swivel of a bridge. Background Currently, the infrastructure construction of China is vigorous, a large number of bridges are built, and the spans of the bridges are longer and longer. Along with the development of the economy and society of China, on the basis, people put forward higher requirements on the construction of bridges. From safety and practicability to the need of bridge, the bridge has beautiful appearance, and can be well combined with local history culture and environment.
