Most of the anti-seismic brackets are used in electromechanical earthquake resistance. What is electromechanical shock resistance? Popularly speaking, it is the pipelines and equipment of the electromechanical system, and measures to resist earthquakes. So, what are the mandatory requirements for seismic parts for various parts of electromechanical? The following is a brief explanation from the parts of water supply and drainage, gas, electricity and HVAC.
First, the water supply and drainage part
(1) If the indoor water supply, hot water and fire pipe diameters that need to be fortified are greater than or equal to DN65, when the hanger is fixed, the seismic support shall be set according to the requirements of Chapter 8 of the specification;
(2) When the straight-line length of the water supply and drainage risers of high-rise buildings in the 8th and 9th degrees exceeds 50m, anti-vibration measures should be taken. When the linear length exceeds 100m, anti-vibration measures should be taken;
(3) The water supply pump and other equipment in buildings with 8 degrees and 9 degrees should be equipped with anti-vibration foundation, and the limiter should be fixed around the foundation. The limiter should be determined by calculation.
Second, the gas part
(1) For gas pipelines with an inner diameter of not less than 25 mm, seismic design shall be carried out;
(2) When the gas pipeline passes through the isolation layer, the valve and the shut-off valve should be installed outdoors, and the seismic sensor should be installed, and the seismic sensor and the shut-off valve should be interlocked;
(3) In buildings with a building height greater than 50 m, the gas pipelines shall be provided with seismic support at appropriate intervals in accordance with the seismic requirements of the building.
