Description

  INDUSTRIAL APPLICABILITY The present invention is implemented in the installation work of an air conditioning duct in a building or the like, and contributes to the formation of the open air cylinder air-control opening means mounting structure having an opening at the tip, and the structure. Further, the present invention relates to a method of attaching the air restriction port means of the open cylinder.

FIG. 8 is a longitudinal sectional view showing a conventional example.
As shown in FIG. 8, the conventional open cylinder 1 has an opening 1a in which the front end of the sealed air passage q is opened to the air conditioning / ventilation target room side, and a mounting frame 5 for the air restriction means in the opening 1a. Is interpolated. The air restricting means is a register (not shown) that is provided with a slidable number of adjustable blades after the mounting frame 5 is fixed to the inner surface of the open end of the open cylinder 1 that is a duct. This is a universal register that is fixed by screwing it onto the internal flange of the mounting frame 5 with a bolt.

  In the open cylinder 1, when the mounting frame 5 is fixed at an appropriate position in the open cylinder 1, is a tapping screw r screwed into the mounting frame 5 and the open cylinder 1 as illustrated? Alternatively, as disclosed in, for example, Patent Documents 1 and 2, the mounting frame 5 and the open cylinder 1 are coupled via a band-shaped member.

  When fixing with the screw member r, the tapping screw r is screwed in from the inside of the mounting frame 5 using an electric screwdriver or the like. However, since the inner side of the mounting frame 5 is narrow, the rotating shaft of the electric screwdriver is horizontal. It was difficult to position in the direction, and work was difficult.

  On the other hand, in order to improve such a situation, for example, in the case of the technique disclosed in Patent Document 1, a belt-shaped member made of a metal plate is engaged with a slit formed in the open cylinder 1. According to such a technique, the air in the open cylinder 1 leaks outward through the gap between the slit and the belt-like member.

In the case of the technique disclosed in Patent Document 2, a strip-shaped member made of a nonmetallic material such as a hook-and-loop fastener is used. At this time, when air is circulated in the open cylinder 1, dust or the like may adhere to the band member and condensation may occur in the open cylinder 1 to wet the band member. As a result, the band member May rot and become unsanitary.

  Next, an example of a procedure for forming the air-control opening means mounting structure according to the present embodiment in association with the ceiling surface of the building will be described with reference to FIGS. Here, FIGS. 6 and 7 are explanatory views showing the formation procedure of the air vent opening means mounting structure.

  In the factory, as shown in FIG. 1 based on the design drawing, one in which the band-like members 4a and 4b are fixed in the open cylinder 1 is manufactured and transported to the work site.

  And the cylinder main-body part 2 is arrange | positioned vertically in the space above ceiling plan height in the building which is a work site, and is fixed through a suitable support means. At this time, the lower end edge of the tube main body 2 is substantially matched with the indoor surface height of the ceiling plate 26 to be attached as shown in FIGS. Further, the air holes of an air conditioning ventilation duct (not shown) already installed in the building and the opening 3a of the connection port 3 are communicated with each other through a flexible cylinder. After that, the ceiling plate m is attached. In this case, a square-shaped through hole is formed in the ceiling plate m at a position directly below the cylinder main body 2 and the lower end of the cylinder main body 2 is inserted into the through hole. Let

  Next, the mounting frame 5 of the air restriction port means is pushed inward through the opening 1a of the opening cylinder 1 by manual work or the like. At this time, each of the belt-like members 4 a and 4 b is located between the outer surface of the outer peripheral enclosure 6 of the mounting frame 5 and the inner surface of the tube main body 2. During the pushing operation of the mounting frame 5, the belt-like members 4 a and 4 b are pushed together with the cylindrical main body portion 2 and elastically displaced by pushing the lower square tubular portion 7 toward the center line a 1. It will not be an obstacle.

  When the flange portion 7c of the mounting frame 5 approaches the indoor surface of the ceiling plate 26, the lower ends of the strip members 4a and 4b reach the flange portion 7c. At this time, the lower ends of the strip members 4a and 4b are inserted into the through holes g2. To process. Thereafter, as shown in FIG. 6A, the attachment frame 5 is pushed into the tube main body 2 until the flange portion 7c comes into contact with the interior surface of the ceiling plate 26, and the belt-like member 4a is kept while keeping this pushed state. As shown in FIG. 6B, the lower part of 4b is bent into the inner back side so that its tip is upward as shown in FIG. Since the through hole g2 extends to the flat surface portion 7a, the bent portion is bent within the range of the flat surface portion 7a and does not protrude to the position of the flange portion 7c.

  As a result, the mounting frame 5 is stably suspended from the belt-like members 4a and 4b in the cylinder main body 2, and the flat portion 7a of the lower rectangular cylinder 7 is in the cylinder main body 2 under this condition. The four flat surface portions 7a are pressure-bonded to the inner surface of the tube main body portion 2 and the band-like members 4a and 4b in order to expand outward due to elasticity inside, so that no loose gap is generated in the mounting frame 5. As a result, the occurrence of rattling noise and the like due to the floating gap during use is prevented.

  Next, as shown in FIG. 7A, the register portion 10 is brought close to the air restriction port means 2 from below the cylinder main body portion 2, and the rectangular cylinder portion 11 of the register portion 10 is fitted in the lower portion of the lower rectangular cylinder portion 7. Combine. Thereafter, as shown in FIG. 7B, the elastic packing member 15 of the flange portion 14 is pushed up until it is pressed against the lower surface of the flange portion 7 c of the mounting frame 5. While maintaining this pushed-up state, the bolt 16 is inserted into the hole of each hole forming piece 13 from the lower side, and the tip thereof is connected to the female screw part of the female screw hole forming piece 17 at the corner of the middle rectangular tube part 8. Screw and fasten.

  Thereby, the register portion 10 is pressed against the lower surface of the flange portion 7c of the mounting frame 5 through the elastic packing member by the pulling force of the bolt 16, and the upper end of the edge portion 14a is brought into contact with the indoor surface of the ceiling board m. It becomes a state. At this time, the elastic packing member 15 is pressed against the lower surface of the flange portion 7 c of the mounting frame 5 to cover the through hole g 2, and the gap between the flange portion 14 of the register portion 10 and the lower end of the outer peripheral enclosure 6 of the mounting frame 5. Contributes to dense filling.

  The air inlet means mounting structure formed as described above is used for blowing air in an air-conditioning ventilation duct (not shown) to the indoor side through the open cylinder 1, the mounting frame 5, and the register portion 10, or On the contrary, it is used for sucking indoor air into the air-conditioning ventilation duct through the register portion 10, the mounting frame 5, and the open cylinder 1.

  In the use of the air restriction port mounting structure, the shutter 18 is closed by operating the vertical input shaft member 21 of the rotation input portion 22 of the mounting frame 5 when blocking the flow of air in the open cylinder 1. Further, when changing the blowing direction of air to the indoor side, the swing angle around the fulcrum axis h1 of the blade member 12 of the register unit 10 is changed. Further, when it is desired to prevent the mounting frame 5 and the like from being seen through the space between the blade member 12 groups of the register unit 10 from the indoor side, this can be dealt with by changing the swing angle of the blade member 12.

  Next, in the above embodiment, the structure attached to the ceiling surface is shown. However, when the air inlet means mounting structure according to this embodiment is formed on the vertical wall surface in the room, the center line a1 represents the posture of the previous embodiment. It changes so that it may become horizontal, and it is set as the structure which replaced the ceiling board m with the wall surface material, The other point is not different from the case of previous embodiment.
