Steel grid structures are widely used due to their light weight, high spatial rigidity, good seismic performance, economical materials, convenient construction, and beautiful appearance. However, with the development of large-span buildings, the scale of steel grids is getting larger and larger, and the grid structure form is becoming more and more complex, making the construction of grids more difficult. At the same time, in order to pursue fast and low-cost construction, the probability of quality and safety problems occurring in steel grid structures during construction increases.

[0003] The existing public patent number is: CN218916738U, which discloses a steel structure grid deflection detection device, involving a technical field related to the deflection detection device, including a support seat, a support frame is fixedly installed on the upper surface of the support seat, a detection device is fixed at the top center of the support frame, a threaded rod is rotatably installed on the top of the support frame, and a group of sliders are threadedly connected to the outer wall of the threaded rod, and extrusion plates are fixedly installed at the bottom of the two sliders. A limiting plate on which the steel structure grid can be placed is provided on the side where the two extrusion plates are close to each other. By rotating the threaded rod, the two sliders can respectively drive the extrusion plates to approach or move away from each other, thereby changing the distance between the two extrusion plates, and then the steel structure grids of different lengths are placed between the two limiting plates.

[0004] The above scheme utilizes a detection device to detect its deflection, so that the existing deflection detection device can detect steel structure grids of different lengths, reducing the error caused by the detection result of the detection device. After the steel grid is used, due to its high height, the staff need to take a lift for inspection, which is very troublesome and safety cannot be guaranteed.
