[0002] The seismic suspension system for assembled electromechanical equipment is a technology used in the building electromechanical installation industry. It has been optimized and improved in design, warehousing, prefabrication, assembly, etc. The main advantages of this system are its safety, environmental protection, economy and efficiency. It can improve the seismic performance of building electromechanical facilities and improve the stability of equipment installation.

[0003] The existing mechanical and electrical equipment is generally installed by planting reinforcement or post-anchoring hanger bars on the building structure beams and slabs. When there are earthquake-resistant requirements, earthquake-resistant supports and hangers are set. The earthquake-resistant supports and hangers are also post-anchored at the bottom of the structural beams and slabs. This post-anchoring form drills holes at the bottom of the beams and slabs, especially in the bottom area of ​​the concrete beams and slabs, which can easily cause cracks in the concrete structure. It is also common to repeat the drilling of the main reinforcement position after post-anchoring, which is not conducive to the safety and weather resistance of the beam and slab structure.
