[0002] With the rapid development of modern scientific research buildings, the demand for structural precision is becoming increasingly stringent. This is especially true for geometrically complex structures, such as single-story circular structures above ground. Traditional measurement methods face numerous challenges due to their unique geometry and biaxial nonlinear grid layout. During construction, such complex structures place extremely high demands on the high-precision positioning of the steel structure. Any slight deviation can impact the overall performance and safety of the building. This is especially true in the micro-vibration environments of scientific research buildings, where precise positioning is crucial and can even affect the normal operation of subsequent scientific research equipment and the conduct of research.

[0003] To this end, we designed a steel structure construction measurement method for micro-vibration control in scientific research buildings. Summary of the Invention

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0030] like Figure 1 As shown, the present invention discloses a steel structure construction measurement method for building micro-vibration control, wherein the building may be a building with a dual-axis nonlinear axis grid layout, such as a single circular scientific research building on the ground; specifically, the method comprises the following steps:

[0031] Step S1, reviewing the primary network benchmark points based on the primary network coordinate system provided by the survey unit (the primary network benchmark points are the benchmark points in the measurement control point results table provided by the survey unit), and using a total station to resurvey and adjust the primary network benchmark points based on the primary network coordinate system provided by the review survey unit; wherein the primary network coordinate system is a geodetic coordinate system.

[0032] Step S2: Figure 2 and 3As shown, a secondary grid coordinate system is established with the center point of the original design drawing as the origin. The secondary grid coordinate system is the construction site coordinate system. The BIM model of the steel structure is used and the CAD software is used to transpose the adjusted primary grid reference points into reference point coordinates in the secondary grid coordinate system (see X1 and X2 in the figure). Secondary grid control points are added in the construction site (see P1, P2, P3, P4 and P5 in the figure), and the increased number is ensured to cover the entire construction area. The reference point coordinates and secondary grid control points both include steel column control point 1.

[0033] Specifically, in the above step S2, the coordinates of the secondary network control points are associated with the coordinates of the reference points to form a complete control network system, and the secondary network control points (newly added control points) are marked and recorded.

[0034] The steps of building the BIM model of the steel structure specifically include: collecting design drawings, geological survey reports, planning documents and other materials, using BIM software (such as TEKLA) to establish the BIM model of the steel structure, numbering and labeling the steel structure components in the BIM model, and using the coordinate conversion method of CAD software to associate and export the coordinate system in the BIM model and the coordinate information of each component with the coordinate system of the construction site (secondary grid coordinate system) so as to unify the coordinate system and quickly locate the position of each component during construction, and transpose the steel column control point 1 with the construction site coordinate system.

[0035] Step S3: Figure 4 As shown, in the line-of-sight area, a total station 3 is set up at the construction site according to the coordinates of the steel column control point 1 in the secondary grid coordinate system, and the steel column assembly 2 is installed using the coordinates of the steel column control point 1 in the secondary grid coordinate system, and the steel column assembly 2 is adjusted, wherein the steel column assembly 2 includes a steel column and a reinforcement assembly.

[0036] Specifically, in the above step S3, the step of adjusting any steel column assembly 2 includes:

[0037] Step S31, as Figure 5 As shown, the site of the total station 3 adjacent to the steel column assembly 2 (i.e., the total station located near the steel column assembly 2 and relatively close to or closest to the steel column assembly 2) is used as the origin (i.e., its coordinate point is reset to zero), and together with the first ray 4 (two points on the line are selected), a three-level grid coordinate system perpendicular to the steel column assembly 2 is established, wherein the first ray 4 is a ray perpendicular to the steel column in the steel column assembly 2 drawn from the origin of the secondary coordinate system to the steel column assembly 2, and at the same time, the coordinates of the steel column control point 1 in the secondary grid coordinate system are transposed into the coordinates of the steel column control point 1 in the tertiary grid coordinate system through the software, and the transposed data are remeasured through the origin (0,0) of the tertiary grid coordinate system. The three-level grid coordinate system is a local coordinate system.

[0038] Step S32, as Figure 6 As shown, the installation position of the steel column assembly 2 is adjusted unidirectionally using the steel column control point 1 in the three-level grid coordinate system.

[0039] Step S33, transpose the steel column control point 1 in the third-level grid coordinate system back to the second-level grid coordinate system, and re-measure and adjust the steel column assembly through the corresponding steel column control point 1 in the second-level grid coordinate system. After meeting the requirements, reinforce the steel column to complete the installation of the steel column assembly 2.

[0040] In the embodiment of the present invention, due to the unidirectionality of the adjustment of the steel column assembly 2 and the problem of the angle of the positioning axis of the secondary grid coordinate system, the adjustment of the steel column is difficult, so it is necessary to introduce a tertiary grid coordinate system.
