Technical Field

[0001] This utility model relates to the field of curved beam installation and positioning technology, and in particular to a curved beam rebar limiting device. Background Technology

[0002] Curved beam bridges have a more complex structural form, which makes them more load-bearing and suitable for areas with high vehicle speeds and volumes. In addition, curved beam bridges usually use steel or hybrid structures, which makes them more earthquake-resistant. As some of the older bridges in various places have developed various defects, the "creep" problem of curved beam bridges has gradually attracted widespread attention.
