Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a corbel structure for supporting a distribution beam of a small-radius curved bridge on complex terrain. Background Art

[0002] When building a bridge between general bridge piers, the common method is to use pre-fabricated bridge modules to build it directly between the two piers; however, for complex terrain and curved locations, the common method is generally to use a cast-in-place method. This cast-in-place bridge requires the construction of a Bailey frame to support the concrete casting mold, and the Bailey frame is supported by a scaffolding. However, this method is generally suitable for flat ground and low-height piers. Under complex terrain, it is impossible to set up a scaffolding to support the Bailey frame, which requires a corbel structure to be set up on the cast bridge supporting pier to support the Bailey frame; the general corbel structure is installed by setting prefabricated parts on the bridge pier to install the corbel structure, and the height of the distribution beam placed after the corbel structure is installed is fixed, and the height of the corbel support can only be adjusted by adding or removing pads, which is very inconvenient to operate.
