Description

Technical Field

[0001] The present invention relates to the technical field of steel arches, and particularly relates to a cross-bridge type steel arch installation and forming device. Background Art

[0002] The through-type tied arch bridge structure has great advantages for steel structure bridges. It combines the arch rib and the longitudinal beam to jointly bear the load, and combines the structural performance of the beam in bending and the arch in compression. It can avoid setting a very rigid bearing platform due to large horizontal forces. In the construction of the through-type tied arch steel bridge, the method of constructing the longitudinal beam first and then the arch rib can be adopted. However, for long-span tied arch bridges, when constructing by the method of constructing the longitudinal beam first and then the arch rib, temporary supports need to be added, hoisted and constructed in segments. After the construction of the steel arch bridge is completed, the temporary supports are removed. When the bridge construction is completed and the supports are removed, the arch rib and the longitudinal beam need to be separated from the temporary supports to prevent harmful internal forces from being generated in the steel arch bridge after the temporary supports are removed. However, before the temporary supports are removed, it is difficult to reliably determine whether the distance between the arch rib and the longitudinal beam separated from the temporary supports meets the requirements, and it is impossible to ensure the reliable removal of the temporary supports.

[0003] The installation between the existing arch surface and the column is very monotonous, which may cause the arch surface and the column to be unable to operate for a long time, resulting in danger. Summary of the Utility Model
