These dry air duct systems connect ducts made of PVC or Galbarium (aluminum galvanized) materials to each floor, allowing natural exhaust from roof tops.

Hereinafter, a conventional exhaust duct system will be described in detail with reference to the accompanying drawings.

1 is a schematic view showing a conventional exhaust duct system.

1, in the conventional exhaust duct system, a main duct 1 formed by connecting a plurality of granular ducts 2 is installed in a vertical direction of a building, and a branch duct (not shown) connected to the kitchen or toilet of each floor 3 are connected to the main duct 1 and an exhaust fan 4 is installed at the uppermost portion of the main duct 1. Therefore, the kitchen fan and the toilet air of each floor can be forcibly discharged to the outside through the branch duct (3) and the main duct (1) by the exhaust fan (4).

The plurality of granular ducts 2 constituting the main duct 1 are installed to pass through the through holes H formed in the slabs S of the respective layers and the granular ducts 2 of the lower granular ducts 2, And the portion to which the duct 2 is connected is connected by the connecting and supporting band 5. That is, as shown in detail in FIG. 1, the flange portions 2a formed on both ends of the connecting portions of the upper and lower ducts 2 are wrapped with a V-shaped cover portion 6a formed on the band 5, The supporting flange 6d integrally formed at the lower end of the band 5 is held by the peripheral edge of the through hole H of the slab S to prevent the granular duct 2 from sagging At the same time, by closing the through hole (H), smoke and flame are prevented from propagating to the upper layer when a fire occurs.

However, in order to install the conventional exhaust duct system having the above-described structure, it is necessary to fix the granular duct 2 to the slab S and to connect the upper and lower two granular ducts 2 to each other, (5), and it takes a long time to install the exhaust duct system.

Further, the support flange 6d of the band 5 is generally joined to the slab S by a separate engaging piece. 1, when the bottom surface of the supporting flange 6d is brought into close contact with the upper surface of the slab S, the fitting piece passing through the supporting flange 6d can not be sufficiently inserted into the slab S, 6d can not be stably coupled to the slab S.

In addition, in the conventional exhaust duct system, when the support flange 6d is bent by an external force, the through hole H is opened, and smoke and flame easily propagate upward when a fire occurs.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of an exhaust duct assembly according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a cross-sectional view illustrating a structure in which a fixing duct and a fixing band are coupled to a slab, and FIG. 4 is a cross- Sectional view showing a structure in which an exhaust duct assembly according to the present invention is coupled to a slab.

The exhaust duct assembly according to the present invention is a type of exhaust system installed through a slab S so as to be connected to a plurality of branch ducts installed in each floor of a multi-house. An exhaust duct is installed in each slab S The present invention is not limited to the process of connecting the exhaust ducts arranged in series with the process of joining the exhaust ducts, but it is possible to connect a plurality of exhaust ducts in a single joining process, so that the construction is very simple.

That is, the exhaust duct assembly according to the present invention includes a fixed duct 100 formed vertically through the slab S and having a fixing flange 110 formed at an upper end and a lower end thereof, A fixing band 200 coupled to both sides of the fixed duct 100 and a connection flange 410 arranged in line with the fixed duct 100 and closely contacting the fixing flange 110 in a laminated structure at the upper and lower ends, A connecting band 500 coupled to upper and lower sides of the connecting duct 400 and coupled to the fixing band 200 in a laminated structure, And a fastening piece (600) for fastening the fastening piece (200).

The fixing flange 110 is installed to penetrate the slab S before the slab S is installed. In the course of pouring the concrete for making the slab S, the fixing flange 110 is slab- S on the upper surface or the lower surface thereof.

The fixing band 200 is installed on the upper side and the lower side of the fixed duct 100 and includes a fixed vertical part 210 surrounding the outer circumferential surface of the fixed duct 100 and a fixed horizontal part 210 extending from the end of the fixed vertical part 210, And a fixed horizontal part 220 extending in the direction of the arrow. The fixing band 200 mounted on the upper side of the fixed duct 100 is positioned such that the fixed horizontal part 220 is inserted between the fixing flange 110 and the upper surface of the slab S, The fixed band 200 to be mounted is positioned such that the fixed horizontal portion 220 is inserted between the fixed flange 110 and the bottom surface of the slab S. [ At this time, the fixing band 200 is integrally formed in a ring shape and is connected to the fixed duct 100 in a process in which one side is divided and both ends divided by the separate coupling bolts 230 are coupled, Is welded to the fixed duct 100 by spot welding, so that even if the concrete installation pressure is applied, it can not be detached from the fixed duct 100.

At this time, the fixing band 200 may be configured such that both ends divided by the coupling bolts 230 as in the present embodiment are coupled to each other, or may be formed into a single ring shape without a divided point. The structure of the fixing band 200 is manufactured in various forms and is commercialized for various purposes, so that a detailed description thereof will be omitted.

The connecting band 500 is mounted on the upper side and the lower side of the connecting duct 400 like the fixing band 200 and includes a connecting vertical portion 510 surrounding the outer circumferential surface of the connecting duct 400, And a connection horizontal part 520 extending horizontally from an end of the fixing part 510 to cover the fixing horizontal part 220.

The fastening piece 600 is fastened so that its end passes through the connection horizontal part 520 and the fixed horizontal part 220 so that the connection horizontal part 520 and the connection horizontal part 220, (410) and the fixing flange (110) are pressed together. That is, the exhaust duct assembly according to the present invention connects the fixed duct 100 and the connecting duct 400 only by coupling the connecting horizontal part 520 and the fixed horizontal part 220 using the fastening piece 600 The airtightness between the fixed duct 100 and the connecting duct 400 can be formed, and the entire installation of the exhaust duct assembly becomes very simple, thereby significantly shortening the construction period.

In addition, the exhaust duct assembly according to the present invention is configured to completely isolate the indoor space of each floor, and it is also expected that the phenomenon of fire spreading or smoke diffusion between neighboring floors is also prevented.

Meanwhile, the fixed duct 100 included in the exhaust duct assembly according to the present invention includes at least one horizontal bead 120 and a slanted bead 130 so as not to be bent or deformed easily even when an external force is applied in the course of pouring concrete. There is a further feature in that it is formed.

Since the beading formed in the conventional duct is formed only to surround the outer circumferential surface of the duct horizontally, the beading is formed in the conventional duct. However, the external force applied diagonally or the vertical direction external force There is a problem in that it can not have structural rigidity.

However, if both the horizontal bead 120 and the oblique bead 130 are formed like the fixed duct 100 included in the present invention, not only the horizontal external force but also the external force applied obliquely or the vertical external force, As a result, there is an advantage that deformation and breakage due to external force can not be easily generated.

The horizontal beading 120 and the slanted beading 130 are formed on one fixed duct 100 and two slanted beading 130 are formed on one fixed duct 100. However, May be varied in various ways. The horizontal bead 120 and the slanted bead 130 may be formed not only in the fixed duct 100 but also in the connecting duct 400.

5 is a perspective view of a space securing bracket included in an exhaust duct assembly according to the present invention.

When the entire one surface of the fixed horizontal part 220 is brought into contact with the upper surface or the bottom surface of the slab S, the end of the fastening piece 600 for fastening the connection horizontal part 520 and the fixed horizontal part 220, ). In this case, since the slab S is made of concrete having a very high strength, the coupling piece 600 is not inserted into the concrete and is highly likely to be broken. Thus, the connection horizontal part 520 is fixed to the fixed horizontal part 220 So that it can not be assembled firmly.

In order to solve such a problem, an exhaust duct assembly according to the present invention includes a space securing bracket 300 for securing a securing space in which concrete is not filled at a point where the securing piece 600 is fastened to the slab S May be additionally provided. The space securing bracket 300 includes an engaging portion 310 fixedly coupled to one surface of the fixed horizontal portion 220 (the bottom surface of the upper fixed horizontal portion 220 and the upper surface of the lower fixed horizontal portion 220) And the bending portion 320 is bent to be drawn into the slab S in the middle portion thereof.

When the space securing bracket 300 is provided, the concrete can not flow smoothly into the fastening space between the bending part 320 and the fixed horizontal part 220 when the concrete is inserted for the slab S construction. , The fastening space becomes empty. Therefore, the connecting vertical part 510 and the fixed vertical part 210 can be more stably fastened without fear that the end of the fastening piece 600 is in direct contact with the slab S. In addition, when the fastening space is secured at the point where the fastening piece 600 is fastened, the operator can more easily fasten the fastening piece 600, so that the construction period of the exhaust duct assembly according to the present invention is remarkably shortened .

In this embodiment, only the case where the space-holding bracket 300 is interrupted is shown as a 'V' shape. However, if the space-holding bracket 300 can secure a fastening space, Or may be bent at right angles in a rectangular groove shape. That is, the space-holding bracket 300 may be replaced with any shape as long as it can prevent the concrete from flowing into the fastening piece 600 fastening path.

6 and 7 are the second embodiment and the third embodiment of the space-holding bracket.

When the space securing bracket 300 included in the present invention is formed in a bent shape as in the embodiment shown in FIG. 5, one side of the fastening space (the side opposite to the fixed duct 100) is open, There is a possibility that some concrete may be introduced through the concrete.

Therefore, in the space-holding bracket 300, the blocking plate 330 is formed at both sides of the coupling space a in the width direction so that the bending portion 320 is blocked at all sides and an opening is formed at one side It can be formed into a concave container shape. When the bending portion 320 is formed in the shape of a concave container, the space securing bracket 300 is installed such that the opening portion thereof faces the fixed horizontal portion 220, and the inner space of the bending portion 320, Concrete will not enter the space at all. That is, since the fastening piece 600 is secured by the empty space in which the concrete is not introduced at all, the fastening piece 600 can be fixed to the connecting horizontal part 520 without any fear of interference with the concrete. So that it can be stably fastened to the horizontal part 220.

6, in order to manufacture the bending portion 320 in a concave container shape, the bending portion 320 may be formed by bending the strap-shaped plate to form the bending portion 320, The barrier plate 330 is additionally formed on both sides in the width direction of the base plate 310. [ In order to further form the blocking plate 330, the process of manufacturing the blocking plate 330 and the process of welding the blocking plate 330 must be performed. Thus, the space securing bracket 300 is manufactured There is a problem in that it takes a lot of time and cost.

The exhaust duct assembly according to the present invention can prevent such a problem that even if a separate blocking plate 330 is not formed in the space securing bracket 300, So that it can not be influenced. 5, the bending portion 320 is formed by bending the strap-shaped plate, and the bending portion 320 is formed in the fastening space a, as shown in FIG. 7, The styrofoam 340 may be additionally provided.

The styrofoam 340 is a material having flexibility so that the end of the fastening piece 600 can be inserted very easily, but can prevent the concrete from being introduced into the re-space. 7, if the styrofoam 340 is additionally provided in the fastening space a of the bending portion 320, even if a separate blocking plate 330 is not provided, It is possible to prevent the concrete from flowing into the fastening space (a), so that the fastening piece 600 can be easily fastened.

At this time, if the styrofoam 340 has ductility enough to easily insert the clamping piece 600 and can have a compressive strength of a certain level or more to prevent the inflow of concrete, it is possible to use various materials such as sponge and synthetic resin ≪ / RTI >
