The invention discloses a horizontal duct wall penetrating
system and a construction method thereof. The horizontal duct wall penetrating
system comprises a duct
assembly, a fixing ring and a sealinglayer; the duct
assembly horizontally penetrating through the wall and includes a duct, a casing arranged on the outer side of the duct in a sleeving mode, and a connecting
assembly that connects theduct to the casing fixedly; the length of the casing is adapted to the thickness of the wall, and a gap is reserved between the casing and the duct; a
fireproofing plugging material is filled in the gap; the connecting assembly include a bolt, an outer
washer and an inner
washer; the bolt is arranged in the casing, the
fireproofing plugging material and the duct in sequence in a penetrating mode;the outer
washer is arranged between the outer wall of the casing and the bolt in a laid mode, and the inner washer is arranged between the inner wall of the duct and the bolt in a laid mode; and thefixed ring is arranged on the duct in a sleeving mode, the duct is fixed to the inner side face of the wall, and the sealing layer is sealed on the outer side of the
fireproofing plugging material. Bymeans of the horizontal duct wall penetrating
system, the technical problems that when a traditional duct is installed, the danger is high, the labor consumption is high, the casing is easily pressedto be broken, and the plugging effect is not good.
