This structure not only has excellent bearing capacity, but also can meet the needs of modern buildings for space utilization. When there is a suspended ceiling under the tube truss, the suspended ceiling of the large-span space of the tube truss often requires a suspended ceiling conversion frame, which is mostly connected to the lower chord of the tube truss by welding. However, high-altitude welding requires special technicians to hold certificates, is difficult to operate, is difficult to ensure welding quality, and has an adverse effect on the original steel structure, such as increased residual stress.
