Abstract

The invention discloses an intelligent deformation detection system for a large building steel structure, and belongs to the technical field of engineering detection. The intelligent deformation detection system for a large building steel structure comprises a pedestal, jacks and precision levels. A first driving rod is rotationally connected into a first sliding groove, mounting bases are in threaded connection with the first driving rod, and a first driving part is connected to the pedestal. Mounting boxes are fixedly connected to the tops of the jacks, second driving rods are rotationally connected to the mounting boxes, clamping blocks are in threaded connection with the two ends of the second driving rods, and second driving parts are connected to the mounting boxes. A second slidinggroove is formed in the side wall of a mounting groove, a third driving rod is rotationally connected into the second sliding groove, a third driving part is connected to the pedestal, a cross rod anda mounting plate are fixedly connected to the top of a supporting rod, and the precision levels are slidably connected to the mounting plate.

[0002] Steel structures are widely used in buildings, such as the Great Hall of the People, the National Grand Theater, stadiums and other large buildings. Usually, giant steel trusses are used to support the entire roof. Necessary deformation observations are carried out on such large roof trusses to grasp the deformation laws of the roof truss structure It is of great significance to ensure the safety of buildings; however, the top space of some large historical buildings is airtight, the steel beams are staggered, the scale is large, and the light is not good, which leads to deviations in the detection of building deformation by observation instruments, causing serious consequences

[0003] In order to avoid the occurrence of the above situation, a concept of simulated building appeared, but in the simulated building, due to the variety of structural parts used, it is impossible to truly simulate the stress of various steel structural parts during actual installation. Simulated buildings bring certain obstacles; therefore, an intelligent deformation detection system that can cooperate with detection in real time and accurately measure the deformation of large building steel structures is needed
