Abstract

The invention relates to a rounded building ventilation exhaust duct. The rounded building ventilation exhaust duct is characterized in that a duct body is a rectangular cavity duct; end faces of the duct body are perpendicular to the outer wall thereof; at least one of four edges of the duct body is internally provided with a reinforcing bar; at least one inner wall corner of the duct body is internally provided with a reinforcing bar; the combinations of any side and any inner wall corner of the duct body are internally provided with reinforcing bars, respectively. The rounded building ventilation exhaust duct has higher vertical compressive strength and has the advantages such as excellent strength, fire resistance, water resistance and light weight.

Description

A kind of fillet building ventilation extract duct
Technical field
The present invention relates to a kind of fillet building ventilation extract duct.
Background technology
There is the technical problem that Vertical Compression power is little, resident family's living safety rank is low in the product of existing building particularly under house kitchen, washroom and public domain partial ventilation extract duct standard-required.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is the fillet building ventilation extract duct providing a kind of practicality, improves the Vertical Compression of constructure ventilation extract duct, has good strength, the features such as fire prevention, waterproof, light weight.
For reaching above-described object, following technical scheme taked by a kind of fillet building ventilation extract duct of the present invention:
A kind of fillet building ventilation extract duct, it is characterized in that, described extract duct main body is rectangular enclosure pipeline, and its end face and pipe main body outside wall surface perpendicular.
In four limits of described extract duct main body, in having at least, reinforcing rib is set.
The inwall intersection of described extract duct main body, has at least in a place and arranges reinforcing rib.
In any limit of described extract duct main body and combination place of any inwall intersection, all reinforcing rib is set.
Described inwall intersection is R arc transition chamfering.
Described extract duct main body side arranges fire-preventing check valve and installs preformed hole.
Described rectangle is rectangle.
Described rectangle is square.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
Improve the Vertical Compression of constructure ventilation extract duct, there is good strength, the features such as fire prevention, waterproof, light weight.
Accompanying drawing explanation
Fig. 1 is the embodiment of the present invention one structural representation.
Fig. 2 is the embodiment of the present invention two structural representation.
Detailed description of the invention
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
Embodiment one
As shown in Figure 1, a kind of fillet building ventilation extract duct of the present invention, adopt rectangular cavity pipeline as extract duct main body 1, its inwall intersection 2 is R arc transition chamfering, end face and pipe main body outside wall surface perpendicular.In two limits of extract duct main body 1, in four inwall intersections 2, be all provided with reinforcing rib 3.Extract duct main body 1 side arranges fire-preventing check valve and installs preformed hole 4.
Embodiment two
As shown in Figure 2, a kind of fillet building ventilation extract duct of the present invention, adopt square cavities pipeline as extract duct main body 1, its inwall intersection 2 is R arc transition chamfering, end face and pipe main body outside wall surface perpendicular.Reinforcing rib 3 is provided with in four inwall intersections 2 of extract duct main body 1.Extract duct main body 1 side arranges fire-preventing check valve and installs preformed hole 4.
This programme improves the Vertical Compression of constructure ventilation extract duct, ensure that building body vented exhaust quality, improves working stamndard.
It is more than the explanation to the specific embodiment of the invention, this programme not only limits in the embodiment above, the such as setting of reinforcing rib 3 orientation and quantity, except the arranging of embodiment, also can arrange on other limit or intersection, and combination place of any limit and any inwall intersection is arranged, magnitude setting is not also limited with one.All will fall in scope for any change made under this programme inventive concept.
