Technical Field

[0001] The present application relates to the technical field of bridge tower cross beams, and in particular to an inverted diamond-shaped bridge tower cross beam support and a construction method thereof. Background Art

[0002] At present, the construction of bridge towers requires the production of tower columns in stages. When the tower columns reach a certain height, they need to be reinforced by lower and upper beams between the two tower columns to prevent the tower columns from bending due to being too high. However, in the production of beams, the lower beam is often produced first. When the upper beam is produced, the beam bracket needs to be reinstalled and the upper beam is produced. However, after the lower beam is produced, the beam bracket of the lower beam will be disassembled, resulting in a waste of materials.

[0003] With respect to the above-mentioned related technologies, the inventor believes that after the lower crossbeam is manufactured, the crossbeam bracket will be idle. Summary of the invention
