In order to improve the seismic performance of buildings, on October 9, 2014, the Ministry of Housing and Urban-Rural Development officially issued the Code for Seismic Design of Building Mechanical and Electrical Engineering, which was officially implemented on August 1, 2015. The code stipulates that the mechanical and electrical engineering of buildings in areas with seismic fortification intensity of 6 degrees and above must be designed for earthquake resistance, in order to reduce the damage to mechanical and electrical engineering equipment caused by earthquakes. In the seismic system of electromechanical engineering, the anti-seismic support and hanger is an important part; the anti-seismic support and hanger can resist the horizontal seismic force, and in the event of an earthquake, the seismic force can be transmitted to the structure connected to it through the diagonal bracing of the support and hanger. body, and minimize the relative displacement and shaking between the electromechanical piping and the building structure.

At present, in the existing anti-seismic support and hanger, the upper end of the load-bearing hanger and the inclined-stayed channel steel are fixedly connected to the top building structure through the upper connecting base, and the lower end is connected to the equipment pipeline through the lower connecting base. The steel is connected to the connection base by a single bolt and nut. Due to the continuous shaking during the earthquake, the bolt and nut connection structure is prone to loosening, resulting in unstable cable-stayed fixing and affecting the overall stability of the seismic support and hanger.
