Problems solved by technology
[0003] In order to ensure the safety of the basement structure, reverse construction has higher requirements on the plane center point, top surface elevation, axis distribution, and verticality of the structural steel column. In actual construction, it is often difficult to meet all technical indicators at one time. Construction control Difficult, so room for improvement

The invention provides a positioning platform and positioning method for a foundation pit reverse construction method steel structure column, and belong to steel structure column construction devices.The positioning platform comprise an upper operation platform, a lower adjusting platform, a cross beam set, an adjusting device and two hoist hook devices, wherein the two hoist hook devices are correspondingly arranged on the two sides of the lower adjusting platform; the lower adjusting platform is arranged in the shape of a rectangular frame; the cross beam set comprises four cross beams arranged on the four side faces of the lower adjusting platform correspondingly; the adjusting device comprises at least one (preferably two) adjusting bolt arranged on each cross beam, wherein the adjusting bolts are in threaded connection with the cross beams, and the ends of the adjusting bolts abut against the steel structure column; and the hoist hook devices are used for fixing the elevation position of the top of the steel structure column. According to the positioning platform and positioning method for the foundation pit reverse construction method steel structure column, the problems that all technical index requirements are difficult to meet at a time in actual construction and that construction control difficulty is large due to the fact that requirements for a plane center point,a top face elevation, axis distribution, perpendicularity and the like of the structural steel structure column are high in reverse construction can be solved.
Description
technical field [0001] The invention relates to a construction device for a steel structure column, in particular to a positioning platform and a positioning method for a steel structure column of an upside-down foundation pit method. Background technique [0002] When the underground building (structure) is designed to be constructed by the upside-down method, the structural columns are usually constructed before the excavation of the foundation pit. When the structural column is designed in the form of a steel column, the overall structure is that the bottom of the foundation pit is a cast-in-situ pile, and the top of the foundation pit is a steel column, and the steel column is inserted into the bottom of the cast-in-place pile for about 3m. [0003] In order to ensure the safety of the basement structure, reverse construction has higher requirements on the plane center point, top surface elevation, axis distribution, and verticality of the structural steel column. In act...
