FIELD PREVENTION SLEEVE FOR DRY TYPE AIR DUCT SYSTEM, CONSTRUCTION STRUCTURE AND METHOD USING THIS FIELD [0001]

The present invention relates to a fireproof sleeve for a dry air duct system and a construction structure and method using the fireproof sleeve. More particularly, the present invention relates to a fireproof sleeve for a dry air duct system, And to a structure and a method of construction using the fireproof sleeve for a dry air duct system.

Generally, in a multi-story building such as an apartment or a multi-generational building, a dry air duct system is installed on the side of the kitchen and the bathroom side in order to normally exhaust the odor generated from the kitchen side and the bathroom side of each household.

The DRY TYPE AIR DUCT SYSTEM connects air ducts made of PVC or Galbarium (aluminum galvanized) to each floor to allow natural or forced exhaust from the roof top.

In the dry air duct system, a plurality of granular air ducts are vertically connected to each other in a vertical direction and are connected to one side of the granular air duct, and saddles are installed to be fixed to a flexible duct in a kitchen or bathroom side, The uppermost layer of the granular air duct is provided with an exhaust perforated plate, and an exhaust fan is provided above the exhaust perforated plate.

At this time, upper and lower connecting ends of the granular air ducts are connected and fixed on the upper and lower straight lines by using connection members such as connecting bands or couplers. In the slab part made of concrete, a slab Are interposed and connected by the guidance of the sleeve.

That is, the upper air duct and the lower air duct are respectively butted to the upper and lower ends of the sleeve inserted and disposed in the interlayer slab, and then the butt portion is butt-joined by fastening a connecting member such as a connecting band or a coupling.

However, there has been a problem in that a gap space is formed between the sleeve and the air duct which is butt-coupled with the sleeve, and the formation of such a clearance space causes the passage of toxic gases and flames in the lower layer to the upper layer when a fire occurs in the multi- .

In order to solve this problem, there has been adopted a method of interposing a sealing member of elastic material between the gap between the sleeve and the air duct, but the sealing process is not easy and the operation is troublesome.

In the prior art, a sleeve having a flange portion at the upper and lower ends is formed to have the same inner diameter as the vertical exhaust pipe, and the stopper portion has a plurality of fastening holes The vertical exhaust pipe flange portion and the sleeve flange portion are closely contacted with each other and the plurality of fastening bolts are fastened to the fastening holes of the load distribution portion of the earth stopper coupled to surround the outer circumferential surface of the vertical exhaust pipe, The present invention proposes and discloses a configuration relating to a vertical exhaust pipe connection structure of a dry air duct system in which a vertical exhaust pipe and a sleeve are connected so as to communicate without leakage, have.
