Further, reference numeral 48 is a parting edge attached along the edge of the cover 12 facing the cutout portion 36, and 50 is a slit plate covering the cutout portion 36.

Further, FIG. 3C shows an exploded perspective view of the ventilation duct 18. The ventilation duct 18 is, in order from the top, the column connecting pipe 5
2, wire band 54, upper flexible duct 56 made of aluminum, nipple 58, ventilation pipe 60,
It is composed of a fireproof damper 62, a lower flexible duct 64, and a ventilation chamber 66. In the claims, the fireproof connecting material means the fireproof damper 62 and the nipple 58. The ventilation chamber 66 has a slit plate 40.
The ventilation port 16 is attached to the inner surface of the drawing (see FIG. 3B). The ventilation chamber 66 is attached by fixing the attachment claw 67 and the ventilation gallery 44 with screws. Further, the lower flexible duct 64 is externally fitted to a flange 69 provided around the ventilation hole 68 of the ventilation chamber 66 and is disposed inside the cover 10. Cover 1 for ventilation pipe 60
It is inserted into the pipe insertion hole 34 of the straightening member 22 near the boundary between the first floor and the second floor, which is interposed between 0 and 12, the lower end is connected to the lower flexible duct 64 via the fire protection damper 62, and the upper end is connected to the nipple 58. It is connected to the upper flexible duct 56 via. The upper flexible duct 56
The duct insertion hole 2 of the correction member 22 interposed in the cover 12
6 and the column connecting pipe 52 is attached to the upper end of the wire band 5.
Connected at 4.

FIG. 1 is a longitudinal sectional view showing a state in which the respective parts shown in FIG. 2 are assembled. In the figure, the core member 14 is a square pipe-shaped through column, and is fitted in the groove 24 of the correction member 22 inserted in the covers 10 and 12 and erected upright through the first and second floors of the building. There is. The cover 10 is provided such that the lower end is in contact with the floor 70 on the first floor and the upper end is in contact with the ceiling 72 on the first floor, and the cover 12 is in contact with the floor 74 on the second floor at the lower end and 2 at the upper end.
It is provided in contact with the ceiling 76 of the floor. The upper end of the upper flexible duct 56 is connected to the ventilation system chamber 78 via the column connecting pipe 52 and opens to the outside through the back of the hut.

Further, FIG. 3 shows a front view of the pillar.

According to the pillar thus configured, one end of the ventilation duct 18 is connected to the ventilation port 16 and the other end is opened to the outside, so that the indoor air is exhausted to the outside from the ventilation port 16 through the ventilation duct 18. . In this way, since the exclusive ventilation duct 18 is arranged in the covers 10 and 12, there is no air leakage, the ventilation air volume can be kept constant, and the ventilation performance is improved.

Further, since the air passes through the ventilation duct 18, the covers 10, 12 and the floors 70, 74 and the ceilings 72, 7 as in the conventional case.
6, the connection with 6, the cover 10, 12 and the slit plate 40,
Since it is not necessary to consider the airtightness of the connection parts with 42, 50, etc., the on-site construction can be easily performed and the quality is stable.

Furthermore, water vapor generated in the room does not leak into the covers 10 and 12 or the room on the second floor, and can be discharged to the outside through the ventilation duct 18, so that dew condensation occurs on the inner surfaces of the covers 10 and 12 and the room. It can be prevented.

Further, as shown in FIG. 2C, the ventilation duct 18 is
Flexible ducts 56 and 64 are connected to both sides of a ventilation pipe 60 arranged near the boundary between the upper and lower floors through a fireproof connecting material such as a fireproof damper 62, and the lower flexible duct 64 is connected to a ventilation chamber 66. Since the upper flexible duct 56 is connected to the ventilation port 16 and the upper flexible duct 56 is opened to the outside from the pillar connecting pipe 52, even if a fire occurs, there is a risk that the ventilation duct 18 will spread the fire from the lower floor to the upper floor or the upper floor to the lower floor. There is no.

Further, since the ventilation duct 18 is covered with the cover 10, the flexible ducts 56 and 64 that form the ventilation duct 18 are provided.
It is not damaged and has excellent durability. Further, the shape of the cover 10 is maintained by the correction member 22, and the correction member 22 has a function of positioning the ventilation duct 18 and the electric wiring by the groove 24 and the pipe insertion holes 32 and 34. Along with this, in addition to the ventilation function, electric wiring can be neatly bundled and passed through this pillar. In addition,
Due to the flexibility of the flexible ducts 56 and 64, even if the mounting positions of the column connecting pipe 52 and the ventilation chamber 66 are changed, they can be dealt with.

〔The invention's effect〕

According to the pillar of the present invention, the ventilation duct is passed through the cover,
Since one end of this ventilation duct is connected to a ventilation window that is open to the inside of the room and the other end is open to the outside, the air in the room is exhausted to the outside from the ventilation window through the ventilation duct. in this way,
Since a dedicated ventilation duct is installed in the cover, there is no air leakage and the ventilation performance is improved, and since air passes through the ventilation duct, it is not necessary to consider the airtightness of the cover, and field construction can be performed easily. .

In addition, the ventilation duct is made by connecting flexible ducts to both sides of the ventilation pipes located near the boundary between the upper and lower floors through a fireproof connecting material such as a fireproof damper, and the lower flexible duct via the ventilation chamber. Since the upper flexible duct is connected to the ventilation port and is opened to the outside from the pillar connecting pipe, even if a fire occurs, there is no risk of fire spreading from the lower floor to the upper floor or from the upper floor to the lower floor through the ventilation duct.

In addition, since the ventilation duct is covered with the cover, the flexible duct and the like that form the ventilation duct are not damaged and have excellent durability. Further, the shape of the cover is maintained by the correction member, and the correction member has a function of positioning the ventilation duct and the electric wiring by the groove and the pipe insertion hole. Along with this, in addition to the ventilation function, electric wiring can be neatly bundled and passed through this pillar. In addition,
Due to the flexibility of the flexible duct, it is possible to cope with changes in the mounting positions of the column connecting pipe and the ventilation chamber.
