Description

Technical Field

[0001] The utility model belongs to the technical field of tied arch bridge construction, in particular to an arch rib assembly bracket system for preventing out-of-plane tilting. Background Art

[0002] The tied arch bridge is installed in the order of tie rods first and then arch ribs. Several support systems are set up below the tie rods. After the tie rods are installed, they are extended above the support system to achieve the installation of the arch ribs.

[0003] Generally, tie rods are used to lock the tie beam bracket and the arch rib bracket on the tie rods. This process is relatively complicated to construct because the arch rib bracket is in an unstable state during the entire installation process, and the crane must not be unhooked during the entire process. The construction efficiency is low, and the risk gradually increases when there are other bridges or pipelines around. In addition, the stability of the arch rib bracket only depends on the reliability of the locking tie rod. When subjected to lateral forces such as impact, it is easy to cause instability. When there are existing traffic and pipeline structures around, the risk of loss is high.

[0004] For example, the construction method of a large-span steel tube concrete arch bridge disclosed in a Chinese invention patent with an application publication date of 2024.03.12 and application publication number CN117684471A includes the following steps: erection of temporary supports, erection of arch foot formwork supports, construction of tie beams, installation of steel tube arch splicing auxiliary devices, and construction of hangers.
