What are the classification and arrangement principles of fabric air duct ventilation ducts and fabric air duct ventilation ducts for seismic support? The anti-seismic bracket can fully protect the electromechanical systems in the earthquake and resist the damage of the seismic force in the horizontal and vertical directions. According to the different protection electromechanical systems, seismic support can be divided into pipeline seismic support system, pipeline seismic system and electrical seismic system. First, the classification and configuration principles of seismic support. 1. The lateral interval of pipeline seismic reinforcement is the pipeline of rigid material such as groove connection pipeline, welded steel pipe, brazed copper pipe, etc. The interval between horizontal hangers shall not exceed 12m for pipes made of non-rigid materials such as HDPE, and the interval between horizontal hangers shall not exceed 6m. 2. The longitudinal spacing of pipeline seismic reinforcement requires grooves to connect pipes with rigid materials such as pipes, welded steel pipes, and brazed copper pipes. The vertical hanger spacing shall not exceed 24m for pipes made of non-rigid materials such as HDPE, and the horizontal hanger spacing shall not exceed 12m. Second, the configuration principle of pipeline seismic support system. 1. The maximum spacing of the lateral seismic hangers for ordinary rigid pipes is 9m, and the maximum spacing of the longitudinal seismic hangers for ordinary rigid pipes is 18m. 2. For the side seismic hangers of non-rigid materials such as fiberglass and plastic, the maximum spacing is 9m. Third, the configuration principle of the electrical seismic support system. 1. The lateral seismic spacing of rigid wire pipes, trunking and bridges shall not exceed 12m, and the longitudinal seismic spacing shall not exceed 24m. 2. The horizontal anti-seismic interval of wire pipes, trunking and bridges of non-rigid materials shall not exceed 6m, and the longitudinal interval shall not exceed 12m. Fourth, the calculation principle of seismic support system. The installation form and configuration principle of the seismic support are determined by strict mechanical calculation results, and the calculation of seismic force must meet the requirements of the code. The seismic support has scientific and strict mechanical calculation design software. On the basis of satisfying the seismic mechanical calculation, the material utilization rate is extremely high! The anti-vibration support of the ventilation duct should be added with a seismic support in the middle. The drilling of the anti-vibration bracket should use a bench drill, and it is strictly forbidden to use flame cutting. The right-angle bracket should be turned at the corner, and the turn should be smooth and even. The bracket should be free of thorns, cuts, welding leaks, etc., and there are damaged parts after installation. Even before painting the anti-corrosion and anti-vibration bracket, the section steel should be adjusted. Small steel blanking is cut by grinding wheel cutting machine, and large steel can be cut by flame. The extended edge and burr of the cut end face are polished with a grinding wheel grinder to ensure the beauty of the cut end face. The installation of the riser load-bearing bracket must be firm and reliable, the form used and the quality of the combined welding must meet the requirements, the load-bearing test must be carried out if necessary, and the bracket and pipeline anchorage must be firm. The position of the piping support is correct, horizontal and vertical, flat and firm, and is in close contact with the piping. The pipe is fixed on the bracket, and the U-shaped pipe clamp is used. When making fixed tube clips. About seismic support of ventilation ducts In order to reduce earthquake damage and minimize and prevent secondary disasters, mechanical and electrical engineering facilities such as building water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, and communications must be equipped with seismic support. The construction of seismic support hangers mainly involves the use of anchors, reinforced hangers, seismic connection parts, piping connection parts, seismic diagonal braces, section steel and fasteners. Anti-seismic brackets are used for the conversion of bearing force, which can well control the instability that occurs when steel links are connected. For the anti-seismic support treatment of different finished products, it can be moved in different positions. Improving the installation of different accessories can increase or reduce the resistance of the anti-seismic support, effectively preventing the loss of the ability to control the moving support in long-term use. The use of vibration force can avoid the phenomenon of high expansion of force and water level, adjust the height of the force used by different steel supports, and reduce the phenomenon that vibration and vibration force are difficult to operate.
