(1)PVC塑料通風(fēng)管是磚墻，對于支管，應(yīng)在磚墻上開一個管槽，用管夾將管子直接預(yù)埋固定在管槽內(nèi)。管槽寬度應(yīng)為管外徑De+20mm，槽深應(yīng)為管外徑De，只要管不露出磚墻面即可。埋有溝槽的管道盡量不使用管件，溝槽的彎曲半徑應(yīng)滿足管道的小彎曲半徑。</div> <div> </div> <div> (2)如果是鋼筋混凝土剪力墻，支管應(yīng)鋪設(shè)并附著在墻面上，并用管夾固定在墻面上。土建墻面施工時，用高級水泥砂漿抹平，或用鋼網(wǎng)包裹在管道外側(cè)(管道局部墻面或全部墻面)，用水泥砂漿抹平，然后在外側(cè)粘貼瓷磚等裝飾材料。</div> <div> </div> <div> (3)在吊***內(nèi)敷設(shè)時，要有意彎曲方向，做***支撐架。</div> <div> </div> <div> (4)對于有兩三個衛(wèi)生間且穿過客廳的住戶，一種方式是將管道直接埋在地板找平層的管道內(nèi)(僅適用于De20)。埋在找平層內(nèi)的管道不得有接頭?；蚵裨阡摻罨炷翗前鍍?nèi)，但必須有套管，并有防止混凝土灌入套管的措施。</div> <div> </div> <div> (5)立管應(yīng)敷設(shè)在管道井內(nèi)。</div> <div> </div> <div> (6)廚房的管道應(yīng)鋪設(shè)在櫥柜后面，但不必嵌入墻內(nèi)。隱蔽立管應(yīng)在其穿越樓板處做成固定支撐點，防止立管的累積膨脹在上支管的連接點產(chǎn)生位移應(yīng)力。除立管De≤40mm穿越樓板處的固定支承點外，每層中間應(yīng)設(shè)兩個支承點，De≥50mm立管，層間僅設(shè)一個支承點。</div> <div> </div> <div> 支撐點不必等距離設(shè)置，但***在立管引出支管的三通接頭處設(shè)置一個支撐點。立管布置在管道井中時，應(yīng)在立管引出支管的三通接頭處設(shè)置一個固定支承點，中間支承仍應(yīng)按上述原則設(shè)置。土建施工只能在試壓后無滲漏的情況下進(jìn)行。</div> <br></div> <div id="5sbsdi8m6l"
