There is a difference between load-bearing support and seismic support. The names of many stents are derived from their uses. Due to the development and use of the industry, a large number of similar names are habitually used: pipe gallery bracket, photovoltaic bracket, bridge bracket, fire protection bracket, cable bracket, optical fiber bracket and so on. Some of these supports belong to the category of load-bearing supports. However, according to their different uses, uses and specialties, they also have their own special processes and components, which cannot be confused.
However, seismic bracing can not be simply understood as load-bearing bracing plus diagonal bracing. Because the load-bearing support has the assembly method (waste 2 1 13 support) and the traditional method, the seismic support has more lateral (T or lateral longitudinal (T+L) support than the load-bearing support. Moreover, 526 1 different bearing brackets bear different mechanical and electrical equipment (such as ventilation pipes, fire-fighting pipes, cable trays, bus ducts, etc.). Moreover, their models, sizes, dimensions and weights are different, so it is impossible to simply add diagonal braces to become seismic braces. Because the design of seismic bearings should take into account that mechanical and electrical equipment can be maintained under earthquake conditions and seismic force can be transmitted to the main structure 4 102, different mechanical and electrical equipment will have different seismic bearing designs, which is why seismic bearings cannot be sold separately, but must be sold in sets. This is also the reason why the seismic bearings determined by national codes, industry codes 1653 and acceptance codes are a complete system.
