Description

Duct Assembly and Constructing Method

The present invention relates to a duct assembly and a method for constructing the same, and more specifically, the upper and lower covers that form the duct assembly by being coupled up and down can be manufactured for a long time without fear of bending deformation, and the construction of the ceiling surface can be easily performed. The present invention relates to a duct assembly and a construction method which can visually check the overall length of a straight duct coupled to a fitting duct and disassemble the duct to enable internal cleaning.

In general, a ventilation system including a duct for intake or exhaust guiding the air should be provided in the building in order to allow outside fresh air to flow into the room or to distribute the polluted air to the outside.

The method of constructing such a duct on the ceiling of a building is performed by a worker cutting a straight pipe duct of a predetermined length so that the left and right ends are opened by a separate cutting tool such as a saw or a scissors according to the required length, and both ends of the cut pipe duct. Finish the cuts clean.

Then, the lubricant is applied to the inner surface of the end portion of the fitting duct to be connected to the straight duct duct and then connected by inserting one end of the cut straight duct, and the 'c' shaped clip is fixed as a bolt member on the ceiling surface The straight duct connected to the tungsten duct was firmly positioned to attach to the ceiling surface.

The fitting duct may include a coupling duct for connecting two straight ducts in a longitudinal direction, and an elbow duct and a straight duct for converting the flow path of the straight pipe duct in another direction, a right angle, or an inclined direction into two flow paths. It is provided with any one of the T-shaped ducts which switch in the other direction.

In the case of the straight duct of such duct pipe, in the manufacturing process of extrusion molding in the longitudinal direction to have a hollow pipe shape made of plastic such as PVC, if the length of the forming is extruded long, the central portion of the length sag due to its own weight Therefore, there is a limitation in manufacturing the length of the duct provided by straight pipes longer than 2m, as well as the heavy weight and volume of the duct product, which requires a lot of manpower and work time to transport the duct product to the workplace. Sufficient space must be secured for storage.

Therefore, there is always a risk of secondary holes caused by insufficient overlap between the ducts, and the air flow formed inside the ducts interferes with the end of the straight duct having a rough cut, thereby preventing noise. It acted as an increasing factor.

On the other hand, since the intake duct line and the exhaust duct line must be separately installed on the ceiling surface of the building, it is difficult to simultaneously install the intake duct line and the exhaust duct line on the ceiling surface where the construction area is limited. There were relatively many problems.
