Description

A multifunctional box steel corbel structure

technical field

The utility model relates to the field of bridge construction, in particular to a multifunctional box-shaped steel corbel structure.

Background technique

In the process of bridge construction, climbing cones, steel plates or piercing rods are often pre-buried in the pier body to support the load of the cast-in-situ spanning support of the upper bridge, the cast-in-situ pier body or the cast-in-place construction of the pier cap beam. The strength is often low, and the scope of application is small; the hoop method can be used for conventional bridge cap girder or bridge span cast-in-place construction, but the hoop bearing capacity is not high. If the height of the pier body is high or the bridge span is large , it does not apply.

Patent ZL201420262159.6 "Climbing Corbel" proposes a box-shaped corbel fixed to an embedded part anchored in the wall for climbing formwork support.

The rod hole and the threaded steel hole for the threaded steel to pass through, the steel rod through hole and the threaded steel hole are multiple and arranged at intervals.

The outer side of the box-shaped steel corbel is provided with lifting rings for easy hoisting.

A multi-functional box-shaped steel corbel structure proposed by the utility model adopts the cooperation of the through-core steel rod + fine-rolled threaded steel and the box-shaped steel corbel to support the spanning bracket, pier body, and cover beam formwork body, and has the advantages of simple operation , safe and stable, economical and practical, and reusable, and the utility model is reusable, and the construction process is simple.
