Steel member perpendicularity correcting device for construction of upright column piles

The utility model discloses a steel member perpendicularity correcting device for construction of upright column piles. The steel member perpendicularity correcting device is characterized by comprising a correcting rack (2) and a correcting tube (4); the correcting rack (2) is arranged on an opening of a pile hole (1); the correcting tube (4) is arranged in a steel member (3) and is parallel to the steel member (3); the upper portion of the steel member (3) is perpendicularly connected with the correcting rack (2); and a group of jacks (6) is arranged between the correcting rack (2) around the steel member (3) and the ground (5). The steel member perpendicularity correcting device is large in adjustment range, requirements on perpendicularity of the pile hole are not high, and construction cost can be reduced. Requirements on rigidity of the steel member are not high, and the steel member perpendicularity correcting device not only can be used for constructing steel pipe columns, but also can be used for construction of lattice columns with low rigidity, and is wide in service range. Short edges of the steel member are controlled by a long edge positioned under the ground, occupied area is small, and precision is high. The steel member perpendicularity correcting device is applicable to construction of small-aperture pile holes, accumulated errors are avoided, and perpendicularity adjusting efficiency can be improved.
