Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air supply and exhaust duct for reducing floor height,

The present invention relates to a retractable air supply / exhaust duct for lowering the floor height, and more particularly, to an air supply and exhaust duct for lowering the floor height of a multi-storey building by preventing an installation height of an overlapping point from increasing even if air supply and exhaust ducts cross each other And also to a retractable air supply duct for lowering the floor height which facilitates installation and storage.

According to the related construction law such as building equipment standards, ventilation facilities such as supply ducts and exhaust ducts should be installed inside the apartment ceiling while compulsory application of the ventilation facilities of the apartments.

Usually, the height between the layers is 2,900 m / m, and the height of the inside of the ceiling must be 250 m / m so that the ventilator can be installed.

Air ducts and exhaust ducts should be installed in ceilings of conventional apartments, etc., and sprinklers and fire alarms should be installed separately.

The air supply duct and the exhaust duct are connected to a ventilator for introducing outside air and discharging the air in the room to the outside, and are connected to a plurality of air supply units and a ventilation unit installed in the ceiling of each bedroom or living room.

The air supply unit and the air supply duct serve to supply outside air to the room to refresh the room air, and the ventilation duct and the exhaust duct serve to discharge the contaminated air in the room to the outside.

At this time, when the air supply duct and the air discharge duct are installed in the ceiling, at least one portion of the air supply duct and the exhaust duct intersect with each other.

Accordingly, since the air supply duct and the exhaust duct are overlapped at the intersection, the height of the air supply duct is doubled, and the height of the ceiling interior space is increased to accommodate the air supply duct. Therefore, the indoor space is reduced and the installation cost is increased .

5A, 5B and 5C are cross-sectional views illustrating various examples of installation of conventional feed and exhaust ducts.

5A, the distance between the ceiling cement wall 180a and the ceiling finishing material 185a is 200 m / m, and the air supply duct 110a and the exhaust duct 130a intersect with each other, / m < / RTI > The remaining space of 50 m / m is a space for installing a sprinkler (not shown) or a smoke alarm (not shown).

5B shows another example of installation of the air supply duct 110b and the exhaust duct 130b. As shown in the figure, the interval between the ceiling cement wall 180b and the ceiling finish material 185b is 220 m / m, The duct 110b and the exhaust duct 130b intersect with each other and a space of about 170 m / m is required. The remaining space of 50 m / m is a space for installing a sprinkler (not shown) or a smoke alarm (not shown).

5C shows another example of the installation of the air supply duct 110c and the exhaust duct 130c. As shown in the figure, the interval between the ceiling cement wall 180c and the ceiling finish material 185c is 330 m / m, The duct 110c and the exhaust duct 130c intersect with each other and a space of about 280 m / m is required. The remaining space of 50 m / m is a space for installing a sprinkler (not shown) or a smoke alarm (not shown).

However, since the height of the entire building has to be increased in order to secure the space inside the ceiling, the height of the entire building has already been limited. Therefore, in order to secure the interval between the ceilings of each floor, There was a problem of deteriorating the business performance.

In recent years, various technologies for solving the above-mentioned conventional problems have been proposed.

The inner duct is inserted into the central body 10 through the left and right openings 11 and 11a of the central body 10 so that the inner duct can be slidably moved And the inner front end portion is fixedly connected to the central body 10 by fixing bolts 33 and 43 at upper and lower portions and the outer end portion located at the outside is connected to the exhaust duct 130 or the air supply duct 110 A variable duct 20 which is slid inside the central body 10 and is located on the front side or the rear side is provided inside the front and rear central parts, The air supply and exhaust dividing plates 32 and 42 which divide the space into the front side and the rear side along the air supply duct and the air supply duct connected to the air supply duct 110 and the air supply duct connected to the air discharge duct 130, Left and right supply and exhaust connections (30, 40). In this case,

This can greatly reduce the total floor height without crossing the supply duct and the exhaust duct installed in the ceiling of an apartment or the like, and can smooth the flow of air while reducing the interval between the ceiling of the room.
