Description

The concealed type exhaust duct

The utility model relates to a system exhaust duct, relates in particular to a kind of the block in concealed type exhaust duct within the walls.

In building constructions, be extensive use of a kind of monolithic exhaust duct at present, be installed in kitchen, lavatory, the room pipeline as exhaust or mist extractor.The internal construction of this exhaust duct generally is made of trunk line, branch pipe(tube) and exhaust opening, and more advanced have mozzle and a transformation device, to prevent between the building that smoke blowing is collaborated mutually.At present the exhaust duct that uses has a weak point to be, it is not to build in constituting unified integral body with wall within the walls, but integral hoisting is installed in the outside of wall on floor reservation building wall is finished after.Bring two shortcomings like this, the one, take the room effective area, the 2nd and wall in conjunction with insecure, use after a period of time and between the walls has the crack and less stable occurs.

The purpose of this utility model provide a kind of build in do not account within the walls the room effective area and and body of wall strong bonded concealed type exhaust duct together.In addition, collaborate, exhaust opening has also been done some improvement for effectively preventing smoke blowing.

The purpose of this utility model is to realize like this, exhaust duct main body profile is rectangular cylinder, its height and building height adapt, its thickness and wall thickness equate, two sides are provided with the outwardly directed multilayer reinforcing rib of being made by reinforcing bar parallel to each other about the exhaust duct main body, about two walls outsides the cement reinforcing prop that reinforcing rib and body of wall are combined of cast on-site is arranged.

These reinforcing ribs are fixed together by cement casting and exhaust duct main body when the exhaust pad in shoe is manufactured, reinforcing prop is to make of cement direct pouring at the construction field (site), when needing to lay exhaust duct in the building constructions, this exhaust duct that has a reinforcing rib directly can be built within the walls as the some of wall.Because reinforcing rib places the wall brickwork joint cement about exhaust duct, add the effect of the reinforcing prop of field fabrication, make between exhaust duct main body, reinforcing rib and the wall three firm combination is arranged, so stability better, again since exhaust duct build within the walls, its thickness and wall thickness equate, can not expose outside the wall, thereby not take the room effective area.

The improvement of exhaust opening is to have installed the one way valve that is made of some sagging naturally movable blades in the exhaust opening inboard, each blade of this valve and exhaust opening inwall flexibly connect by two bails, it can be rotated for axle along the line of two bails, blade under the blade that is arranged in is pushed down and is arranged in, thereby blade can only unidirectionally be opened, can prevent effectively that smoke blowing from collaborating.

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment 1 is can be for the exhaust duct of two users' uses of same floor.More than second floor, the exhaust duct shape of every floor is identical, use is chained together mutually, its internal construction as shown in Figure 2, its internal construction is by trunk line (13), branch pipe(tube) (4) and (5), mozzle (6) and (7), exhaust opening (8) and (9) formation, two branch pipe(tube)s are identical with two exhaust opening bilateral symmetry and shape, mozzle (6) is identical with (7) shape, its section is polyline shaped, but the top of one of them exceeds a segment distance than another top, and this segment distance is generally 20-40 centimetre.When cigarette, gas after exhaust opening (8) or (9) enter branch pipe(tube) (4) or (5), upwards flow, mozzle through the exhaust duct of next level enters trunk line, and the flue gas of lower floor enters trunk line (13) from branch pipe(tube) through mozzle (6) or (7) of This floor, and the cigarette of trunk line, gas are discharged from the chimney of roof at last.

4 every layer of the reinforcing ribs of embodiment 1, from the outwardly directed reinforcing rib of left wall of exhaust duct with equate from the outwardly directed reinforcing rib quantity of the right wall of exhaust duct, bilateral symmetry.Symmetrical two reinforcing ribs central axis of wall that is same reinforcing bars before and after the exhaust duct is buried underground and is formed, as shown in Figure 3.There is elbow (12) on the top of reinforcing bar, with the consolidation force of reinforcement and wall.The reinforcing rib interfloor distance is 40-50 centimetre, and bar diameter is the 6-8 millimeter, every the long 40-60 of reinforcing rib centimetre.The situation of reinforcing rib as shown in Figure 1.

Two walls outside is provided with cement reinforcing prop (3) about exhaust duct main body (1), and this reinforcing prop is to be provided with for the firm degree that increases wall and exhaust duct combination.Its height and story height adapt, and thickness is identical with wall thickness, and width is 6-10 centimetre, and the making of reinforcing prop is carried out at the construction field (site), when building a wall after exhaust duct is located, stay the position of reinforcing prop in advance, form with cement casting then.

One way valve (10) and (11) that are made of some sagging naturally movable blades (14) are equipped with in exhaust opening (8) and (9) inboard, and two of every fan leaf go up angle and exhaust opening inwall by bail (15) flexible connection.This blade (14) can be rotated for axle along the on line of two bails, the blade under the blade that is arranged in is pushed down and is arranged in, thus blade (14) can only be opened to the stack internal direction.The effect of one way valve is to prevent smoke blowing and collaborate, when starting smoke exhaust, air-flow can outwards be pushed blade (14) open, flue gas can enter branch pipe(tube), when stopping going up smoke exhaust, blade (14) is sagging naturally, and exhaust opening is blocked, flue gas from pipeline can't be opened blade (14), thereby has prevented in the flue gas inlet chamber.The blade of one way valve can be taken from bail, in the exhaust duct that does not use smoke exhaust, should not install one way valve, in order to avoid influence the unobstructed of air-flow.The blade of one way valve (14) is used the plastics manufacturing, is difficult for corrosion, and is flexible, installs more convenient.Blade (14) is 4, and the shape that combines is identical with the exhaust opening shape.

Embodiment 2 is reduced forms of embodiment 1, it can only use for 1 user, branch pipe(tube) and exhaust opening are kept to one by two, its structure as shown in Figure 4, by trunk line (3), branch pipe(tube) (4), mozzle (6), reinforcing rib (2), exhaust opening (8) and one way valve formations such as (10).Cigarette, gas enter branch pipe(tube) (4) by exhaust opening (8) through one way valve (10), enter trunk line through the mozzle of upper floor exhaust duct.The position of reinforcing rib (2) and reinforcing prop (3) is identical with embodiment 1 with situations such as length.

Embodiment 3 is reduced forms of embodiment 2, also is the simplest a kind of exhaust duct, and its structure as shown in Figure 5.This exhaust duct is not established branch pipe(tube), and flue gas directly enters trunk line (3) by exhaust opening (8) and discharges behind one way valve (10).The position of reinforcing rib and reinforcing prop is also identical with embodiment 1 with situations such as length among the embodiment 3.

Embodiment 1 and 2 can be used as the exhaust duct in rooms such as lavatory, kitchen and bedroom, and embodiment 3 is suitable for being equipped with the room use of smoke exhaust or exhauster.

The utility model has following advantage: because exhaust duct can hiddenly be installed within the walls, do not take The room effective area does not affect the neat appearance in room yet; Because exhaust duct and between the walls have Reinforcing bar is connected with reinforcing prop, has increased the resistance to overturning of exhaust duct and building, makes it ratio More safe and reliable; Owing to installed check valve in the exhaust outlet, can prevent more effectively that smoke blowing from collaborating.
