1)風(fēng)管水平安裝,其直徑或長邊尺寸小于400mm時(shí),間距不應(yīng)大于4m;大于或等于400mm時(shí),間距不應(yīng)小于3m;
1) when the pipe is installed horizontally, its diameter or long side size is less than 400mm, the distance should not be greater than 4m; when greater than or equal to 400mm, the distance should not be less than 3m;
2)風(fēng)管垂直安裝,間距不應(yīng)大于4m,但每根立管的固定件不應(yīng)少于2個(gè)。
2) the vertical installation of the pipe should not be more than 4m, but no less than 2 of the fixed parts of each riser.
2.機(jī)械防排煙系統(tǒng)的矩形風(fēng)道的接縫應(yīng)采用咬口形式,接縫處須保持密封。
2. the joint of the rectangular duct of the mechanical smoke control system should be used as a bite, and the seams must be sealed.
3.送風(fēng)、排煙管道的單位面積允許漏風(fēng)量應(yīng)符合《通風(fēng)與空調(diào)工程施工質(zhì)量驗(yàn)收規(guī)范》GB50243中的規(guī)定。送風(fēng)管道允許漏風(fēng)量應(yīng)根據(jù)工作壓力確定;排煙管道均按中壓系統(tǒng)的規(guī)定。
3. the allowable air leakage per unit area of the air supply and exhaust pipes should be in accordance with the regulations in the code for acceptance of the quality of ventilation and air conditioning engineering construction GB50243. The air leakage of the pipe should be determined according to the working pressure, and the exhaust pipe is according to the regulation of the medium pressure system.
4.管道與風(fēng)機(jī)的連接,宜采用法蘭連接,或采用不燃燒材料的柔性連接。
4. the connection between the pipe and the fan, the flange connection, or the flexible connection of the non burning material should be used.
5.管道穿越隔墻時(shí),管道與隔墻之間的空隙,應(yīng)采用水泥砂漿等非燃燒材料嚴(yán)密填塞。
When 5. pipes cross the wall, the gap between the pipe and the partition wall should be tightly packed with non combustion materials such as cement mortar.
6.排煙管道的隔熱層應(yīng)采用厚度不小于40mm的不燃絕熱材料進(jìn)行隔熱(如礦棉、巖棉、硅酸鋁等)。
6. the exhaust pipe insulation should be used for insulation burning insulation material thickness not less than 40mm (such as mineral wool, rock wool, aluminum silicate, etc.).
