Description
Technical field
The invention belongs to the seal construction methods and its device at a kind of road of lower exhaust upstairs connector.
Background technology
At present exhaust duct is relied primarily in the kitchen of high-rise building, the smoke evacuation of lavatory, ventilation.Exhaust duct is usually that section is in
The tube body of rectangle, the height and story height for often saving exhaust duct adapt to, and each layer exhaust duct is pre- in the exhausting duct of upper and lower floor each other
It stays at mouth after concatenation perforation, building body is discharged from top layer by each floor flue gas of collection.The installation of exhaust duct mainly solves to be vented up and down
At pipeline joint sealing problem and each exhaust duct unify centering and with exhausting duct reserved opening sealing problem.Exhaust between usual two layers
Road junction makees the support of upper end exhaust duct with a reinforcing bar, there is very wide arc gap to be directed between two layers of exhaust duct, then
The gap is blocked with cement mortar, then is sealed with foaming agent, but since exhausting duct reserved opening is located at the angle of building wall mostly,
Above-mentioned method for blocking cannot solve each layer exhaust duct and unify centering, and upper and lower gap gap is removed in the exhaust duct junction between two layers
Outside, there is also control the gap that is staggered；On the other hand, traditional construction method is also the reason of causing leakage cigarette, to be directed at present
It cannot fundamentally solve the problems, such as to leak cigarette at exhaust duct connector.Exhaust duct seam crossing leakage flue gas not only pollutes room air,
Influence exhaust duct ventilation effect.
The mode of the interior socket joint of China Patent Publication No. CN102337780A introductions supporting plate solves to solve exhaust duct company
Interface leaks cigarette problem, though the structure is made good use of compared with conventional seals, but still cannot solve each layer exhaust duct and unify centering, two layers it
Between the left and right of exhaust duct junction be staggered gap and construction method causes leakage cigarette problem, can not fundamentally solve exhaust duct
Cigarette problem is leaked at connector.
Invention content
Therefore, the purpose of the present invention is to design seal construction method and its dress at a kind of road of lower exhaust upstairs connector
Set, can fundamentally solve the problems, such as at exhaust duct connector leak cigarette, have device reasonable design, it is simple and practical, save labor and
