In recent years, earthquakes occur frequently in China, which has a great impact on economic development and social production. With the research and progress of seismic technology, China pays more and more attention to the seismic performance of engineering buildings. The emergence and development of seismic support has gradually become the most common type of modern building construction, In October 2014, the Ministry of housing and urban rural development issued provisions, approved the mandatory standard GB 50981-2014 "code for seismic design of building mechanical and electrical engineering" and implemented it in August 2015. An innovation and revolution in the construction and installation industry is quietly rising.
Seismic supports and hangers are used to support facilities with seismic force as the main load. At present, with the continuous progress of technology, the emergence of finished support promotes the development of seismic support construction. As the main anti-seismic material of building electromechanical anti-seismic system in China, seismic support can reduce the seismic damage of buildings in order to achieve the seismic effect. Earthquake induced ground damage stimulates the need for seismic support reinforcement, especially the secondary disasters caused by earthquake, such as the rupture of ground water pipe, gas pipe and ventilation pipe, and the damage of electrical equipment. Seismic support is mainly through the connection with the base to transmit the earthquake action to the building structure, which has a strong bearing capacity. Therefore, in the design drawings, the reasonable layout should be based on the building layout and electrical lines, which must be executable and reasonable. During the installation and docking, workers should strictly follow the design drawings to ensure the correct position of seismic support, and ensure the integrity of each node combination of seismic support device, so as to ensure the quality of professional construction and installation engineering.
