Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent assembly and monitoring and deviation rectification of steel structure corridors, in particular to a method and system for monitoring and rectifying deformation of intelligent steel structure corridors. BACKGROUND

[0002] In modern construction engineering, steel structure corridors, as structural elements connecting different building blocks and providing pedestrian passages, have been widely used in high-rise buildings, large commercial complexes and other buildings due to their aesthetic appearance and design flexibility.

[0003] However, due to environmental, load and construction process factors, the steel structure corridor may deform and change its posture during assembly and construction, which may affect the stability and safety of the building structure. This is because the traditional assembly and construction process usually lacks real-time monitoring and feedback mechanism, making it difficult for on-site technicians to obtain key data in a timely and accurate manner. When subtle quality problems accumulate to a certain extent, it may be too late to correct. This makes quality control difficult to achieve, and potential problems in the production and construction process are difficult to discover and correct in a timely manner, thereby affecting the quality of the final product.

[0004] Currently, the assembly and construction of super heavy steel structure corridors use steel lattice columns or steel columns as the jig of the steel corridor, and use instruments such as total stations for irregular observation, manual calculation of main beam deflection deformation, which is low in efficiency and cannot be monitored in real time. As the steel corridor is continuously assembled, the dead weight increases, and the deflection changes continuously. By increasing more jigs to cope with the deflection of the steel corridor, more safety risks are added to the assembly and construction of the steel corridor, which is low in efficiency and complex in process, making it difficult to flexibly control the deflection of the main beam of the steel corridor. In addition, existing other professional monitoring systems (existing bridge monitoring systems, etc.) cannot provide a solution for monitoring the overall deflection of the steel structure.

[0005] The present application develops an intelligent steel structure corridor deformation monitoring system and method to monitor the deformation and posture of the corridor in a timely manner to ensure the safe operation of the building. SUMMARY

[0085] S2, whether the deformation of the support column and the middle part of the corridor body is generated is judged according to the midspan main beam deflection;

[0086] For the lower main beam, when γ 下 =0, the deformation measuring points A1, A2 and A3 are on the same straight line, indicating that the beam does not deform; when γ 下 ≠0, the deformation measuring points A1, A2 and A3 are not on the same straight line, then it is judged that the beam has deflected deformation.

[0087] For the upper main beam, when γ 上 =0, the deformation measuring points A4, A5 and A6 are on the same straight line, indicating that the beam does not deform; when γ 下 ≠0, the deformation measuring points A4, A5 and A6 are not on the same straight line, then it is judged that the beam has deflected deformation.
