ntroduce the seismic design requirements of seismic supports. (1) The following equipment and pipelines should adopt seismic supports and hangers: Air-conditioning unit fans with a gravity of 1.8KN. Air ducts with rectangular cross-sectional area greater than or equal to 0.38m2 and circular diameter greater than or equal to 0.7m. Smoke prevention and exhaust duct, accident ventilation duct and related equipment. The indoor water supply, hot water and fire-fighting pipes that need to be fortified are greater than or equal to DN65 horizontal pipes. 8 degree, 9 degree area...

1. Anti-seismic support The anti-seismic support should be reliably connected to the main structure of the structure. According to the seismic fortification intensity of the project location, the seismic force is the main load, and it should be composed of anchors, reinforced booms, seismic connection members and seismic braces. 2. Anti-seismic brackets need to be installed in the following situations (1) Air-conditioning unit fans with a gravity of 1.8KN. (2) Rectangular cross-sectional area is greater than or equal to 0.38 square wood and circular diameter is greater than or equal to 0.7m for air duct prevention...

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 this, during the construction of modern buildings, the seismic performance is very...

In the construction of electrical and mechanical engineering, seismic supports and hangers have begun to be used compulsorily, but many engineering friends are also strange about this. Since the design of buildings will basically never consider the seismic resistance of electromechanical, seismic supports and hangers have disappeared. Used. But the situation is no longer like that now. The building electromechanical industry has a national standard in the field of seismic resistance, which clearly stipulates the setting and design of seismic support. The above is based on the following questions to make a combing for the seismic support and hanger ·...

The seismic support "Code for Seismic Design of Building Electrical and Mechanical Engineering" GB50981-2014 has been implemented for several years, but when I chatted with you, I still feel that there are still many clear things. Combined with the factory inspection and the understanding of various brands, today's mechanical and electrical contacts hvac -Mu Zili will talk about his understanding and opinions on the issues that everyone cares about based on his own knowledge. 1. What is a seismic support? 2. Which systems do anti...

Traditional supports and hangers only bear vertical loads. When an earthquake occurs, the lateral swing is large, which can easily damage nearby facilities, causing damage to the building's electromechanical engineering system and increasing the difficulty of subsequent maintenance.   The anti-seismic support and hanger uses the triangular stability principle in the form of installation to comprehensively load the longitudinal and lateral forces during earthquakes, and change the dynamic characteristics of the pipeline system from flexible to rigid. Make equipment and pipelines stronger, reduce secondary occurrences caused by earthquakes...

Construction process of pipeline seismic support manufacturing device: drawing optimization→determining the number of pipes and routing→measurement and positioning→summarizing bracket manufacturing and anticorrosion→summarizing bracket device→pipe fitting→paint or marking→acceptance Operation process: 1. Right The construction drawings of the row of pipeline installations are further optimized. According to the number, orientation, elevation, and direction of the pipeline, the operation and maintenance space of the pipeline is reserved, and the method, size and...

On July 3, a 6.5-magnitude earthquake occurred in Pishan County, Xinjiang, and nearly 900 aftershocks occurred. In this earthquake, Anju Fumin’s houses withstood the test and provided a protective umbrella for the lives of local villagers. On the morning of the 6th, the reporter saw in Wukashi Village, Pisina Township, Pishan County, which was more seriously affected, that the earthquake-resistant housing built in the village had obvious seismic effects during the earthquake. None of the houses collapsed, and some houses only appeared. It's just a crack.     It is understood that this time...
