The invention belongs to the field of construction and specifically relates to a formwork climbing support. The formwork climbing support comprises a support body, a platform body erected on the support body, a plurality of turning plates and extension plates, wherein the plurality of turning plates are hinged to the side, close to a wall, of the platform body in an end-to-end mode; and the extension plates are detachably connected to the turning plates. Each turning plate comprises a plate body and lifting and pulling connecting parts arranged on the two sides of the upper middle portion of the plate body and connected with the adjacent plate body in a buckled mode. Each lifting and pulling connecting part comprises a caulking groove formed in each plate body and a lifting and pulling handle, wherein an opening of the caulking groove faces one side of the adjacent plate body; the lifting and pulling handle is hinged to the groove opening of the caulking groove and can be turned outwards onto the adjacent plate body through a hinged point. According to the formwork climbing support, the adjacent plate bodies can be connected in a buckled mode and are not likely to be turned over; the lifting and pulling handles are embedded in the plate bodies; when the plate bodies are connected onto the platform, it is guaranteed that main bodies of the plate bodies are attached to the platform; normal passing is guaranteed; when the turning plates need to be turned up, a user can stretch out the hands deep into notches of lifting plates to lift and pull the caulking grooves so as to lift up the turning plates. The formwork climbing support is convenient to operate and safe.
