　　通風(fēng)管道抗震支架的安裝距離一般為9米設(shè)置一個(gè)側(cè)向抗震支架，18米設(shè)置一個(gè)縱向抗震支架。

　　The installation distance of seismic supports for ventilation ducts is generally 9 meters with a lateral seismic support and 18 meters with a longitudinal seismic support. 

　　對(duì)于直徑大于或等于0.7米的通風(fēng)管道系統(tǒng)，通常在9米處安裝一個(gè)橫向抗震支架，18米處安裝一個(gè)縱向抗震支架。此外，對(duì)于非剛性材料如玻璃纖維、塑料等，其側(cè)向抗震支架的距離可能減小到4.5米，縱向距離減小到9米。

　　For ventilation duct systems with a diameter greater than or equal to 0.7 meters, a transverse seismic support bracket is usually installed at 9 meters and a longitudinal seismic support bracket is installed at 18 meters. In addition, for non rigid materials such as fiberglass, plastic, etc., the distance between their lateral seismic supports may be reduced to 4.5 meters, and the longitudinal distance may be reduced to 9 meters.

　　抗震支架的類(lèi)型包括水管單管、水管綜合管（3-4管、5-6管）、風(fēng)管、橋架和綜合支吊架等。不同類(lèi)型的抗震支架有不同的安裝距離要求。例如，水管單管的規(guī)范側(cè)向間距是12米，規(guī)范縱向間距是24米；風(fēng)管的規(guī)范側(cè)向間距是9米，規(guī)范縱向間距是18米；橋架的規(guī)范側(cè)向間距是12米，規(guī)范縱向間距是24米。

　　The types of seismic supports include single pipe water pipes, comprehensive pipe water pipes (3-4 pipes, 5-6 pipes), air ducts, cable trays, and comprehensive support hangers. Different types of seismic supports have different installation distance requirements. For example, the standard lateral spacing for a single water pipe is 12 meters, and the standard longitudinal spacing is 24 meters; The standard lateral spacing for air ducts is 9 meters, and the standard longitudinal spacing is 18 meters; The standard lateral spacing for cable trays is 12 meters, and the standard longitudinal spacing is 24 meters.
