Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a reinforcing steel binding frame for cap beams. Background Technology

[0002] A cap beam is a horizontal beam installed on top of a scaffolding pier to support, distribute, and transfer the load of the superstructure. A jig is a mold that differs from commonly used single and double row scaffolding. Due to the significant differences in the structural form and weight it supports, jig designs vary considerably. Different equipment and processes result in different jig forms.

[0003] During bridge construction, depending on different terrains or variations in bridge span, there may be two or more types of cap beams. Currently, traditional cap beam rebar binding jigs are commonly used to bind the rebar skeleton of the cap beams. However, because the transverse and longitudinal dimensions of traditional cap beam rebar binding jigs cannot be flexibly adjusted, one set of cap beam rebar binding jigs cannot meet the assembly work of the entire bridge's cap beam rebar skeleton. Therefore, the number of jigs needs to be increased during construction, which increases construction costs and workload. Furthermore, the toothed plates of traditional cap beam rebar binding jigs need to be frequently replaced according to different cap beam models and sizes, resulting in reduced construction efficiency.
