Novel compound oil smoke discharging duct of housing

The invention discloses a novel compound oil smoke discharging duct of housing, and belongs to the field of pipeline structures. The duct comprises a stainless steel plate tube, a concrete layer is poured on the outer side of the stainless steel plate tube, a bonding net is further arranged on the outer side of the stainless steel plate tube, and the bonding net is poured in the concrete layer. When a tendency of separation and disengagement between the concrete layer and the stainless steel plate tube exists, bonding power between the stainless steel plate tube and the concrete layer is to beovercome, bonding power between the bonding net and the concrete layer is also to be overcome, and required power is larger so that the concrete layer and the stainless steel plate tube are not proneto disengaging. The problems that the connection between a stainless steel plate and a concrete layer is not firm and prone to being detached in the prior art are solved. 本发明公开了一种住宅新型复合排油烟气道，属于管道结构领域，包括不锈钢板管体，所述不锈钢板管体外侧浇筑有混凝土
