Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline support and hanger brackets, and in particular to a flexible connection device capable of changing spring stiffness. Background Art
[0002] For a long time, people have paid great attention to the seismic performance of the main structure. With the continuous improvement and improvement of seismic design specifications, the damage to the main structure in earthquakes has become less and less. In contrast, the reliability design of non-structural components has not attracted the attention of designers. Some non-structural components have not even been seismically designed, but only connected with simple structures, which leads to serious damage to non-structural components in earthquakes. Electromechanical pipes and tubes, as the main non-structural components in civil structures, are often damaged in earthquakes. According to the damage assessment of the pipeline system in previous earthquakes, the damage to the support and hanger for electromechanical pipes and tubes is the main reason for the damage to electromechanical pipes and tubes in earthquakes. The damage of non-structural components such as electromechanical pipes and tubes in earthquakes will not only cause serious economic losses, but also may cause the interruption of structural functions, which will affect the relief work for some temporary rescue sites after the earthquake. The damage to the pipeline system of industrial buildings in earthquakes may even cause a series of secondary disasters such as toxic gas leakage, fire, and floods, which seriously threaten people's lives and safety. Therefore, it is of great significance to improve the seismic performance of non-structural components such as pipeline systems in earthquakes, which can ensure the safety of people's lives and property.
[0003] Traditional pipe supports and hangers include seismic braces, which are used to resist the horizontal impact of earthquakes. In related technologies, seismic braces are usually rigidly connected to hangers or buildings using rigid parts, relying on the strength of the material itself to resist earthquakes. In concrete structures, the natural frequency of the main structure itself is small and the characteristic period is long. The natural frequency of the pipeline system connected to the main structure through pipe supports and hangers is also small, so it is easy to tune the frequency with the large-span hub structure, and even resonate. The rigid connection method is very unfavorable for electromechanical pipe complexes or other non-structural components. It will cause a large seismic response of the pipeline system, causing more serious damage to the electromechanical pipe complex supports and hangers, and ultimately causing more serious damage to the pipeline system in an earthquake.
