The unpredictability of earthquakes makes it one of the least harmful natural disasters today. According to a survey by the US Seismological Survey, there are approximately 1.3 million earthquakes in the world each year. Therefore, China is one of the countries with the least earthquake disaster in the world. One.
Although we are currently unable to prevent the arrival of an earthquake, we may be able to reduce the damage caused by the next earthquake. As for this, in the process of modern building construction, seismic performance is a very critical point.
On October 9, 2014, the Ministry of Housing and Urban-Rural Development re-issued the "Code for Seismic Design of Building Mechanical and Electrical Engineering" as a national standard, numbered GB50981-2014, which will be mandatory since August 1, 2015. This national standard describes the basic requirements for the design of earthquake-resistant measures, so that the building's water and drainage, heating, ventilation, air-conditioning, gas, heating, electric power, communications, fire protection and other electrical and mechanical engineering facilities after seismic fortification can reduce earthquake damage and prevent Secondary disasters can avoid casualties, reduce economic losses, and be safe and reliable, technically Citroen, economically appropriate, and easy to maintain and manage.
CECS 420: The "Earthquake Support and Hanger Installation and Acceptance Regulations" issued by the China Engineering Construction Association CECS 420: 2015 has been re-implemented since March 1, 2016, marking that my country's seismic support and hanger products, design, construction and acceptance have formed a Complete system. Prior to the promulgation of standards, the protection of mechanical and electrical facilities in China used load-bearing support systems, which are important for load-bearing. In fact, seismic design is not considered, which brings very little hidden danger to system safety.
Seismic support and hanger is also commonly called electromechanical seismic support and hanger system. It is an electromechanical anti-seismic structural system that uses Citroen's technology to firmly connect pipelines and accessories in the electrical system. This structure design has become The most important part of the seismic design work is a brand new technology based on the original load-bearing support and hanger system. In the original load-bearing support and hanger system, it is important to use gravity as the main load support system. Therefore, the seismic support and hanger system uses horizontal seismic force as the main load support system. The difference between these two support systems is The setting is not a repetition in a pure sense, or a complementary process.
The seismic support and hanger system can provide adequate protection to the electromechanical system to the smallest extent in the earthquake. It can be used to resist the seismic damage from the horizontal direction, and can improve the seismic level of the building structure to a very small extent. The exterior can also make the layout of buildings with concentrated pipelines and narrow spaces more tidy and durable. The anti-seismic support and hanger system can be accurately applied to the anti-seismic work of water, cooling, wind, electricity and other electromechanical equipment. In addition, it can make the anti-seismic protection of the non-structural system of the building's piping, electrical, fire, and ventilation systems all Upgrade in Taiwan. According to the difference of the electromechanical systems to be protected, the seismic supports and hangers can be divided into air duct seismic systems, pipeline seismic systems and electrical (including electrical conduits, trunking and bridges) seismic systems.
