Description

Technical Field

[0001] The present invention belongs to the field of main structure engineering construction, and specifically relates to an adjustable crane rail suspension system for a space grid roof and its construction method. Background Art

[0002] Under the background of the continuous and rapid development of urban economy and the increasing demand for cultural life in our country, more and more large and medium-sized cities are actively building large airports to meet the growing demand for air transportation. Among these airports, the aircraft maintenance hangar, as an indispensable functional building, has an increasingly prominent demand for safety performance and has become an important consideration factor in the design and construction process.

[0003] The key function of the aircraft maintenance hangar is to support the maintenance and repair of aircraft. As one of its core structures, the track beam undertakes the important responsibility of transporting materials and personnel. However, in the actual operation process, the track beam often faces problems such as local overload or stress concentration, which may lead to structural damage and even affect flight safety. At the same time, the erection of the track beam is also restricted by on-site conditions. When arranging the grid nodes, due to various factors such as environmental factors, construction technology, and design limitations, the deviation of the grid node position often occurs, thus bringing difficulties to the smooth erection of the track beam.

[0004] Therefore, a reasonable design of the track beam node is particularly important, which not only relates to the safety and reliability of the track beam itself but also directly affects the operation efficiency of the entire aircraft maintenance hangar. In the design process, factors such as the mechanical properties of materials, load conditions, and construction methods must be fully considered to ensure the stability and bearing capacity of the structure. In addition, for some special structural designs, conventional construction methods may not be applicable, so it is necessary to carry out innovative technical research and scheme design to solve related problems.

[0005] In summary, the design and construction of the track beam node play a crucial role in the aircraft maintenance of the aircraft maintenance hangar. Ensuring its safety and reliability is the basis for improving the maintenance operation efficiency and ensuring flight safety. Through technological innovation and reasonable design, the existing construction problems can be effectively solved, providing a more solid support for future airport construction.
