Extended data:
According to the "Building Law of People's Republic of China (PRC)" and "Earthquake Prevention and Disaster Mitigation Law of People's Republic of China (PRC)", the principle of "prevention first" will be implemented, and mechanical and electrical engineering facilities such as water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity and communication will be strengthened after the earthquake.
When an earthquake with seismic fortification intensity occurs in this area, the earthquake damage can be alleviated, and the occurrence of secondary disasters can be reduced and prevented as much as possible, thus reducing casualties and property losses.
Electromechanical anti-seismic bearing is a kind of component or device that limits the displacement of affiliated electromechanical engineering facilities, controls the vibration of the facilities and transfers the load to the load-bearing structure.
In 20 15, the Ministry of Housing and Urban-Rural Development issued the national standard "Code for Seismic Design of Building Electromechanical Engineering": it was approved as the national standard, numbered: GB 5098 1-20 14, and implemented on August 20 15.
The building electromechanical seismic system consists of riser tube bundle, steel beam and purlin clamp, ring crane, seismic diagonal bracing system, seismic steel hanger and bracket.
In our country, the earthquake-proof work of buildings and their affiliated structures is imminent, so it is of great significance and significance to improve the understanding of the seismic design of building electromechanical quickly.
