個(gè)問(wèn)題:,;、松散、中間有接頭現(xiàn)象,與設(shè)備、器具連接時(shí)必須采用專用接頭;。3. 密閉接線盒安裝的質(zhì)量控制☆ 弱電線路一般選用多根導(dǎo)線穿管通過(guò)有防護(hù)、密閉要求的墻體、板,由于多根導(dǎo)線在一起會(huì)有空隙,就不宜做密閉封堵處理。為了達(dá)到同樣的密閉效果,因此采用密閉盒的模式。為了保證密閉效果,規(guī)定管徑不得超過(guò)25mm,目的就是控制管內(nèi)導(dǎo)線的根數(shù),因管內(nèi)穿線過(guò)多,會(huì)影響密閉效果?!?控制要點(diǎn)如下:① 、預(yù)埋的電氣密閉盒應(yīng)全部找出;② 、密閉接線盒及蓋板應(yīng)選用熱鍍鋅鋼板,厚度≥3mm;③ 、電纜、電線暗配管穿越有防護(hù)、密閉要求的墻體、板時(shí),應(yīng)在墻兩側(cè)或板上下側(cè)設(shè)置過(guò)線密閉盒,盒內(nèi)不得有接線頭,過(guò)線密閉盒穿線后應(yīng)密封,并加蓋板。Civil air defense engineering electrical installation pointsYANG Xinwei ( Zhenjiang Fangyuan Construction Supervision Advisory limited Consultants Ltd, Jiangsu Zhenjiang 212006 ) Abstract: At present, in the construction engineering, defence requirements of the project more.
