[0023] The concept, specific structure and technical effects of the present application will be described clearly and completely in conjunction with the examples and drawings, so that the purpose, features and effects of the present application can be fully understood. Obviously, the described examples are only part of the examples of the present application, not all examples, and other examples obtained by those skilled in the art without creative labor based on the examples of the present application are within the scope of protection of the present application. In addition, all the coupling / connection relationships involved in the patent do not mean that the components are directly connected, but that a better coupling structure can be formed by adding or reducing coupling accessories according to the specific implementation. The technical features in the present application can be combined interactively without conflict.

[0024] As described above, in the existing technology, the measurement and correction of steel members mainly rely on manual operation. The specific process includes: after the steel member is hoisted to the predetermined position, the temporary connecting plate is used for preliminary fixation; then, a plurality of control points are selected on the steel member, and three-dimensional coordinate measurement is performed by a total station. During the measurement and control process, the actual measured coordinate value is compared with the designed coordinate value to adjust the position of the steel member. Once the deviation is found, the worker needs to manually correct by means of a reversing chain, a jack and other tools until the engineering specification requirements are met.

[0025] From the above, it can be seen that the existing technology has great operation difficulty and low efficiency when correcting the steel column, and it is difficult to meet the requirements of modern engineering on installation precision and construction period. Therefore, the present application provides a steel column intelligent correction and installation method, which can realize fast and accurate correction of the steel column, improve the correction efficiency, and effectively avoid the errors caused by manual operation in the traditional correction method.

[0028] Among them, the N section steel column is the lower steel column that has been installed, and the N+1 section steel column is the upper steel column to be corrected and installed.

[0029] In a possible implementation, the midpoints of the end portions of the flanges of the two opposite corbels A on the top of the N+1 section steel column are selected as the correction control points, and a first magnetic 360° small prism 11 and a second magnetic 360° small prism 12 are installed at the correction control point positions.

[0030] In a possible implementation, two correction devices 2 are installed on each of the two opposite faces of the N section steel column, and one correction device 2 is installed on each of the other two opposite faces of the N section steel column.

[0031] Among them, the two correction devices 2 installed on the two opposite faces are used for correcting the N+1 section steel column in the X direction, the Z direction and the plane angle; and the one correction device 2 installed on each of the other two opposite faces is used for correcting the N section steel column in the Y direction and the Z direction.

[0032] In an exemplary embodiment, the correction device 2 comprises an intelligent bidirectional hydraulic jack and a sensor, the intelligent bidirectional hydraulic jack is used for adjusting the vertical direction and the horizontal direction of the steel column, and the sensor is used for acquiring the edge deviation information of the upper and lower section steel columns.

[0033] Optionally, the correction device 2 is fixed on the ear plate at the top of the N section steel column by using a 4.8 grade bolt, the N+1 section steel column is hoisted and connected with the N section steel column by using the crane, the horizontal direction jack of the correction device 2 is tightly pressed against the N+1 section steel column through the automatic clamping function of the correction device 2, so as to achieve the purpose of fixing the N+1 section steel column, and then the crane hook is removed.

[0034] Step two: erect the measuring device 3 at the station point, measure the height of the measuring device 3 after centering and leveling, input the station point coordinates and the back sight point coordinates, erect the large prism 4 at the back sight point, measure the height of the large prism 4, determine the ranging deviation and height deviation by aiming at the back sight point with the measuring device 3 to complete the station setting, and measure the N+1 steel column.

[0035] Step three: derive the three-dimensional model of the N+1 steel column, move the three-dimensional model to the CAD measurement coordinate system, extract the three-dimensional coordinates of the design positions of the small prisms in the CAD measurement coordinate system according to the fixed positional relationship between the small prisms and the correction control points, and input the three-dimensional coordinates into the control system 5, and transmit the three-dimensional coordinates of the design positions of the small prisms to the measuring device 3 through the control system 5.

[0036] In a possible implementation, a steel structure professional detailing software is used to derive a steel structure three-dimensional model in dwg format, and the steel structure professional detailing software includes but is not limited to AutoCAD Structural Detailing, Tekla Structures, BIMSteel, ETABS, SAP2000, PDMS, PKPM, 3D3S, and PS2000, etc. The steel structure three-dimensional model is moved to the design position in the CAD measurement coordinate system, and the three-dimensional coordinates (x1, y1, z1) and (x2, y2, z2) of the design positions of the first magnetic 360° small prism 11 and the second magnetic 360° small prism 12 at the top of the N+1 steel column are extracted in the CAD measurement coordinate system according to the fixed positional relationship between the small prisms and the correction control points of the N+1 steel column. The three-dimensional coordinates (x1, y1, z1) and (x2, y2, z2) of the design positions of the two prisms at the top of the N+1 steel column are input into the control system, and then the control system transmits the three-dimensional coordinates of the design positions of the small prisms at the top of the N+1 steel column to the measuring system.

[0037] Step four: according to the received three-dimensional coordinates of the design positions of the small prisms, the measuring device quickly finds the target through the wide-angle camera and accurately aims through the telescope camera, obtains the installation coordinates of the small prisms, and transmits the installation coordinates to the control system.

[0038] In a possible implementation, the three-dimensional coordinates of the installation positions of the first magnetic 360° small prism 11 and the second magnetic 360° small prism 12 are (x1’, y1’, z1’) and (x2’, y2’, z2’).

[0039] Step five: the control system compares the three-dimensional coordinates of the small prism installation position with the three-dimensional coordinates of the design position to obtain deviation information; the correction device transmits the up-down section steel column butt joint error information X and Y obtained by the internal sensor to the control system.

[0040] The deviation information is (△x1,△y1,△z1) and (△x2,△y2,△z2), wherein △x1=x1-x1’,△x2=x2-x2’,△y1=y1-y1’,△y2=y2-y2’,△z1=z1-z1’,△z2=z2-z2’. If△x1>0,△x2>0 and△x1>△x2, it indicates that the top of the N+1 section steel column is deviated to the x positive direction during installation, and the first magnetic type 360° small prism 11 deviates more than the second magnetic type 360° small prism 12, and the column body is twisted; if△x1>0,△x2>0 and△x1=△x2, it indicates that the top of the N+1 section steel column is deviated to the x positive direction during installation, and the column body is not twisted; the other cases of x direction deviation are sequentially deduced. If△y1>0,△y2>0 and△y1>△y2, it indicates that the top of the N+1 section steel column is deviated to the y positive direction during installation, and the first magnetic type 360° small prism 11 deviates more than the second magnetic type 360° small prism 12, and the column body is twisted; if△y1>0,△y2>0 and△y1=△y2, it indicates that the top of the N+1 section steel column is deviated to the y positive direction during installation, and the column body is not twisted; the other cases of y direction deviation are sequentially deduced. If△z1>0,△z2>0 and△z1>△z2, it indicates that the elevation of the N+1 section steel column is higher during installation, and the first magnetic type 360° small prism 11 deviates more than the second magnetic type 360° small prism 12, and the other cases of elevation deviation are sequentially deduced.

[0041] The error information is obtained by the sensor inside the correction device 2. The error information includes X and Y, wherein X is used to represent the error amount in the X direction, and Y is used to represent the error amount in the Y direction. If X>0, it indicates that there is an error, and the bottom of the N+1 section steel column is deviated to the X positive direction relative to the top of the N section steel column; X=0, it indicates that there is no error; X<0, it indicates that there is an error, and the bottom of the N+1 section steel column is deviated to the X negative direction relative to the top of the N section steel column. Y>0, it indicates that there is an error, and the bottom of the N+1 section steel column is deviated to the Y positive direction relative to the top of the N section steel column; Y=0, it indicates that there is no error; Y<0, it indicates that there is an error, and the bottom of the N+1 section steel column is deviated to the Y negative direction relative to the top of the N section steel column.

[0042] Step six: the control system generates a control instruction according to the deviation information and the error information and transmits it to the correction device. In response to the control instruction, the correction device adjusts and corrects the N+1 section steel column, and after passing the acceptance test, it performs steel column butt joint welding and flaw detection.

[0043] In a possible implementation, after the step seven, the method further comprises:

[0044] The final coordinates of the small prism on the top of the installed N+1 steel column are recorded by the measuring device and transmitted to the control system, so that when the N+1 steel column needs to be replaced, the coordinate record can be directly called for installation, improving work efficiency.

[0045] In a possible implementation, a steel climbing ladder and a fall arrestor are further installed on the steel column for protecting the safety of construction personnel.
