Description
Technical field
It is to be related to a kind of thin-wall member and share be vented more specifically the invention belongs to common exhaust duct for dwelling field
Pipeline.
Background technology
A key name is the utility model patent of " common gas exhaust passage " filed in the applicant 2011 year 01 month 21 days, and this is special
Recorded in sharp file：Common gas exhaust passage is arranged at the inner corner trim in room, and the floor at inner corner trim presets hole, the common gas exhaust passage
Hole is passed through by L-type thin-wall member or is arranged on floor and enclosed the hole and part metope and formed, on common gas exhaust passage
Some air inlets are offered, duty valve is installed at air inlet.
Thin-wall mortar pipe in the dedicated water that the common gas exhaust passage eliminates in existing national sector standard, by L-type thin-walled
Component encloses hole and part metope and forms exhaust duct, and waste gas, by its top discharge, both ensure that original through common gas exhaust passage
Cement mortar light-wall pipe discharge effect, and do not produce the gap plugging problem of former duct wall and metope, row has been effectively ensured
The durability of gas system architecture, simple and reliable for structure, construction, convenient transportation, low cost.
Although the common gas exhaust passage has above-mentioned advantage, the exhaust duct still suffers from problems with：First, L-type thin-wall member
Resistance to compression, anti-impact force is not enough, be easily damaged；2nd, the air inlet position set on L-type thin-walled is limited, the opening of air inlet
Can only be parallel with metope or vertical, when smoke exhaust ventilator placement direction is different, and fit up owner and arbitrarily change air inlet orientation, cause
Shared ventilation system is destroyed with security function using function.
The content of the invention
The technical problems to be solved by the invention are the defect for overcoming prior art, there is provided a kind of simple structure, anti-
Pressure, it is anti-it is flexible can be good, can three directions the thin-wall member and the common exhaust pipe using this thin-wall member of air inlet are set
Road.
In order to solve the above technical problems, the technical scheme is that：A kind of thin-wall member is provided, the moon in room is arranged at
At angle, the default hole of floor at the inner corner trim, the thin-wall member passes through the hole or is arranged on the floor and encloses
The hole and part metope and form common gas exhaust passage, the thin-wall member includes orthogonal first plate, the second plate
And the 3rd plate of two plates of connection.
Present invention also offers a kind of common exhaust duct, it is arranged at the inner corner trim of kitchen or toilet, floor at inner corner trim
Reserved opening, the common exhaust duct is passed through reserved opening or is arranged at and hole is enclosed on floor by thin-wall member described above
Mouthful and inner corner trim metope and formed, the thin-wall member is provided with air inlet.
Thin-wall member in the present invention, due to set the 3rd plate, increase corner post reduce plane of constraint, improve resistance to compression,
Anti- soft impulse ability, improves the mechanical property of thin-wall member, not cracky, is more convenient for manufacturing, transports, installs；Meanwhile, will
When thin-wall member is applied to common exhaust duct, the air inlet of exhaust duct may be provided on the 3rd plate, you can be located at not with the moon
At angle on the parallel or vertical face of metope, solve because smoke exhaust ventilator places orientation difference, finishing owner changes to air inlet direction
It is dynamic and the problems such as cause gas extraction system to be destroyed using function and security function and occur that smoke evacuation is not smooth, pour in down a chimney.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The thin-wall member that the present invention is provided is arranged at the inner corner trim in room, and the floor at the inner corner trim presets hole, described
Thin-wall member is through the hole or is arranged on the floor, encloses the hole and part metope and forms shared exhaust
Road.This thin-wall member includes orthogonal first plate, the second plate and is obliquely installed and connects the 3rd of two plates
Plate.This thin-wall member, due to setting the 3rd plate between the first plate and the second plate, increases corner post and reduces and receive
Power plane, improves resistance to compression, anti-soft impulse ability, improves the mechanical property of thin-wall member, not cracky, the system of being more convenient for
Make, carry, transport, install；Meanwhile, when this thin-wall member is applied into common exhaust duct, the air inlet of exhaust duct can set
Put on inclined 3rd plate, you can be located on face not parallel with metope at inner corner trim or vertical, solve because of smoke exhaust ventilator
Place orientation different, finishing owner changes to air inlet orientation and causes gas extraction system to use function to be destroyed with security function, from
And the problems such as occur that smoke evacuation is not smooth, pour in down a chimney, block, more they tend to building common gas exhaust passage pipe-line system perfect.
Implementing for thin-wall member embodiment of the present invention is described in further detail below in conjunction with accompanying drawing.
Embodiment one
Reference picture 1, is the structural representation of the thin-wall member that the embodiment of the present invention one is provided.The thin-wall member 100 is wrapped
Include orthogonal first plate 110, the 3rd plate 130 of two plates of the second plate 120 and connection.Above three plate is equal
It is slab construction, wherein the 3rd plate 130 is obliquely installed and is connected between the first plate 110 and the second plate 120.Thin-walled structure
Part when mounted, the first plate 110 parallel to inner corner trim a metope, and perpendicular to another metope of inner corner trim；Likewise, second
One metope of the also parallel inner corner trim of plate 120, and perpendicular to another metope of inner corner trim, in the prior art, thin-wall member is applied to
During common exhaust duct, the air inlet of discharge duct can only be air inlet on the first plate 110 or the second plate 120
Opening direction also parallel with inner corner trim a metope, both perpendicular to another metope.Therefore, when the smoke exhaust ventilator of user is placed
Orientation changes, and the air inlet orientation of common gas exhaust passage also needs to change, if air inlet is arranged on the 3rd plate 130, smoke pumping
The placement in any orientation of machine all facilitates and is connected with air inlet, without changing air inlet direction, it is to avoid to gas extraction system air inlet
Change and cause it to use the destruction of function and security function.
In the present embodiment, the first plate 110, the second plate 120 and the 3rd plate 130 by cement as gelling agent mixing
Slurry curing is molded, it is also possible to use other materials as the mixed slurry curing molding of gelling agent.Using cement mortar it is this into
Type mode, makes easy, low cost, and shock resistance and compression strength are high, sturdy and durable；Other materials as gelling agent mixing
Slurry curing is molded, and may be molded to thinner thin-wall member and is used as inner template, and the increasing of at least one of which cement mortar solidification is smeared outward
By force.It should be noted that the first plate 110, the second plate 120 and the 3rd plate 130 also can be by plate bookbinding, bonding or building blocks
Shaping, it is lightweight using plate, it is easy to carry and make installation.
In order to strengthen the intensity of whole thin-wall member, in the present embodiment, the first plate 110, the second plate 120 and the 3rd plate
