In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Embodiment one

A kind of common exhaust duct that provides for the utility model embodiment one illustrated in figures 1 and 2, comprise exterior wall 11, offer some air inlet ports 12 on the described exterior wall 11 in advance, the outside of described exterior wall 11 is installed with some collar tie beams 13, lay bricks or cement pre-fabricated panel composition extract duct 14 by described collar tie beam 13, described each air inlet port 12 is communicated with the upwards setting of outlet 151 of described guide pipe 15 with a guide pipe 15 in being located at described extract duct 14.

Particularly, described guide pipe 15 is a plastic bend tube, and described guide pipe 15 is fixedlyed connected with exterior wall 11 by mortar 16; In addition, the interior outside of described collar tie beam 13 all with described extract duct 14 concordant masonries, and this collar tie beam 13 adopts steel concrete to make.

More specifically, the cross section of described extract duct 14 is any shape in circle, polygon, the abnormity; At least one sidewall swabbing of described extract duct 14 inwalls silt particle slurry, or described extract duct 14 not swabbing of inwall silt particles slurry; Described extract duct 14 Brush for outer wall cement mortar, described extract duct 14 is provided with gauze wire cloth and swabbing silt particle slurry with the junction of exterior wall 11, with the bonding strength between reinforced platoon's feed channel 14 and the exterior wall 11.

A kind of common exhaust duct that present embodiment one provides, flue gas enters from air inlet port 12, by the outlet 151 upwards exhausts of guide pipe 15, makes flue gas waltz through extract duct 14 and discharges.

Embodiment two

Fig. 3 and Figure 4 shows that a kind of common exhaust duct that the utility model embodiment two provides, itself and embodiment one are roughly the same, its difference is: described guide pipe 15 is made by the cement bonded sand slurry, make the longer service life of guide pipe 15, cost is lower, and this guide pipe 15 adopts square structure, and is fixed on the exterior wall 11 by screw 152; Described collar tie beam 13 outsides and described extract duct 14 concordant masonries, inner edge protrudes masonry.

A kind of common exhaust duct that present embodiment two provides, flue gas enters from air inlet port 12, by the outlet 151 upwards exhausts of guide pipe 15, makes flue gas waltz through extract duct 14 and discharges.

Embodiment three

Fig. 5 and Figure 6 shows that a kind of common exhaust duct that the utility model embodiment three provides, itself and embodiment one are roughly the same, its difference is: described each air inlet port 12 is connected with a fire resisting damper 17 in being located at described extract duct 14, the outlet 171 of described fire resisting damper 17 is provided with vertically upward, described fire resisting damper 17 is the common device of prior art, preferred the applicant's patent 200620015363.3-fire-proof valve structure used specifically in discharge flue of kitchen and rest room, this fire resisting damper 17 is fixed on the exterior wall 11 by screw 172.In addition, described collar tie beam 13 outsides and described extract duct 14 protrude masonry, the concordant masonry of inner edge.
