The utility model solves the technical problems by the following technical proposal:

the utility model provides a high-altitude cantilever structure formwork construction platform which is characterized by comprising an H-shaped steel girder, wherein the H-shaped steel girder is arranged at the top of a second floor slab in sequence from top to bottom and is welded with embedded parts on the second floor slab, two ends of the H-shaped steel girder are at least flush with two ends of an uppermost floor slab, the bottom of the right end of the H-shaped steel girder is welded with the top of a first H-shaped steel inclined support, the bottom of the first H-shaped steel inclined support is welded with embedded parts on a third floor slab in sequence from top to bottom, the top of the right end of the H-shaped steel girder is fixedly provided with a first bottom lug plate and a second bottom lug plate, a first pull rod is fixed between the first bottom lug plate and the first top lug plate through high-strength bolts, and a second pull rod is fixed between the second bottom lug plate and the second top lug plate through high-strength bolts.

Preferably, an H-shaped steel vertical support is welded between the bottom of the H-shaped steel main beam and the lower part of the first H-shaped steel inclined support.
