The platform's sinking value is relatively small, making it impossible to measure accurately using a commonly used steel ruler, resulting in significant errors. Summary of the Invention

[0003] This application provides a device and method for measuring the settlement value of a structural platform, which can effectively measure the settlement value of the structural platform and provide a basis for optimizing structural design.

[0004] In a first aspect, this application provides a device for measuring the settlement value of a structural platform, comprising a measuring frame 1, a target measuring block 2, a target measuring block 3, a target measuring block 4, and a TB block 5, wherein: The measuring frame 1 is an irregular solid. Target measuring blocks 2, 3, and 4 are fixed on the measuring frame 1. The working point is the center hole of target measuring blocks 2, 3, and 4. The height Z coordinate of the four center holes is consistent. Target measuring block 3 has two measuring holes, which facilitates the laser tracker to measure on the left and right sides of the object being measured. Any three measuring holes form a surface. Four TB blocks 5 are fixed on the measuring frame 1, which facilitates the laser tracker to measure on the left and right sides of the object being measured and is used to establish a coordinate system. This coordinate system is consistent with the coordinate system of the digital model of the object being measured. The coordinate system of the four measuring holes is consistent with the coordinate system of the four TB blocks. The target measuring block 2 is a single machined part. The machined part has a measuring center hole and four bolt fixing holes. The measuring center hole is a circular hole with a diameter smaller than the diameter of the target ball of the small laser tracker. The four bolt holes are connected and fixed to the measuring frame 1 by bolts. The target measuring block 3 is a single machined part with two measuring center holes and four bolt fixing holes. The two measuring center holes are circular and equal in size, with a diameter smaller than that of the target ball of the small laser tracker. The four bolt holes are connected and fixed to the measuring frame 1 by bolts. The target measuring block 4 is a single machined part. The machined part has a measuring center hole and two bolt fixing holes. The measuring center hole is a circular hole with a diameter smaller than the diameter of the target ball of the small laser tracker. The two bolt holes are connected and fixed to the measuring frame 1 by bolts. The four measuring holes of target measuring block 2, target measuring block 3 and target measuring block 4 have the same diameter and the same height Z coordinate, but different X and Y coordinates; the center points of the four measuring holes are connected to form a surface, which serves as the reference surface of the object being measured; The measuring frame 1 has four TB blocks, each of which is an integral machined part.

The laser tracker simultaneously measures the coordinates of points on the object under test (X1, Y1, Z1), (X1, Y1, Z1), etc. All the above data are imported into the CATIA environment. The differences such as Z1-Z and Z2-Z are the sinking values ​​of the point relative to the surface formed by any three holes among the four measuring holes of the target measuring block 2, target measuring block 3 and target measuring block 4.

[0006] Secondly, this application provides a method for measuring the settlement value of a structural platform using a measuring device, the method comprising: Step 1: Place the laser tracker next to the object being measured.
