[0002] In traditional industrial and civil buildings, pipelines such as water pipes and air ducts are often installed horizontally along the bottom of the steel structure beams. Although this layout has certain advantages in space utilization and construction convenience, it has obvious shortcomings in seismic performance. In the past, pipelines were directly fixed under I-beams. Since there was no effective buffering and shock-absorbing mechanism between the pipelines and the beams, once an earthquake or other strong vibration occurred, there would be severe collision and friction between the pipelines and the beams, which might not only cause serious damage to the pipelines and affect their normal functions, but might even cause safety hazards to the entire structural system, seriously affecting the safety and stability of the building.
[0003] In response to this problem, although the industry has adopted specific pipe racks and rod wrapping assemblies to fix pipelines, that is, the pipe racks are stably installed on I-beams through rod wrapping assemblies to enhance the stability of the pipelines, this traditional fixing method still cannot fundamentally solve the dynamic response and stress concentration problems of pipelines under earthquakes, and its seismic performance still needs to be improved.
