Abstract
The utility model discloses a support structure of a cantilever girder. A plurality of parallelly arranged I-shaped steels and an upper-layer concrete slab are fixed together, the parts of all the I-shaped steels protruding out of the upper-layer concrete slab are supported by Y-shaped support channel steels, opening portions on the upper portions of the Y-shaped support channel steels fixedly support the bottoms of the I-shaped steels, and the bottoms of the Y-shaped support channel steels are fixed on a lower-layer concrete slab. According to the support structure of the cantilever girder, the parts of all the I-shaped steels protruding out of the upper-layer concrete slab are supported by the Y-shaped support channel steels, the structure is safe and reliable, and the construction is convenient.
