Roof beam hanging and column pulling transforming and reinforcing method

The invention provides a roof hanging beam and column pulling reinforcing and transforming method, belongs to the technical field of buildings, and aims to solve the secondary problems that an existing supporting beam and column pulling technology affects the clear height of a building, peripheral components need to be reinforced and the like. According to the technical key points, the method mainly comprises the following steps that a stand column needing to be erected with the steel arch is heightened, a column cap for supporting the steel arch is obtained, the steel arch machined in a factory is conveyed to a construction site to be placed at the heightened column cap, the steel arch is connected with a roof beam to be reinforced through a Y-shaped suspender, and roof loads are transmitted to the steel arch through the Y-shaped suspender. And meanwhile, the prestressed steel cables are additionally arranged at the two arch feet of the steel arch frame to balance horizontal thrust generated at the arch feet
