Description

  The present invention relates to facility equipment installed with an opening provided on the ceiling of a building, and a method for constructing the equipment.

  As equipment installed with an opening on the ceiling of a building, an air cleaner that removes dust and the like with a filter while circulating indoor air and blows out purified air into the room is known. .

  In a conventional air cleaner, a construction method has been adopted in which a reinforcing wooden frame on the back of the ceiling is directly screwed with a bolt through a flange portion of the main body. On the other hand, it is difficult to install a reinforcing wooden frame on the ceiling of a lightweight steel-framed house, and a construction method called a ceiling-mounted type that suspends the device body with anchor bolts from a beam or the like is adopted. There is a case.

  Conventionally, in a ceiling-suspended air cleaner, a sealing member is provided on the upper surface of the flange portion that protrudes outward from the lower side surface of the device body, and the ceiling is configured so that the sealing member is crushed by a predetermined amount. Airtightness is ensured by bringing the upper surface of the flange portion into contact with the lower surface of the panel.

  As a result, if the mounting height of the apparatus main body is not accurately adjusted with respect to the ceiling panel, a gap may be formed between the flange portion of the apparatus main body and the ceiling panel, and airtightness may not be ensured.

  In order to solve such a problem, a technique has been proposed in which a sealing member is provided on the side surface of the apparatus main body to ensure airtightness between the side surface of the apparatus main body and the opening edge of the opening of the ceiling. However, when adjusting the mounting height of the apparatus main body, it is necessary to work while supporting the heavy apparatus main body, so that workability is poor and adjustment takes time.

  In view of this, a technique has been proposed in which a connecting member that connects an anchor bolt suspended from a ceiling and a device main body is provided with a ratchet mechanism (see, for example, Patent Document 1).

  However, even when the mounting height of the apparatus main body is adjusted with a ratchet mechanism, the weight of the apparatus main body is applied to the ratchet mechanism, so that it is necessary to work while supporting the heavy apparatus main body. I can't.

  Also, in the ratchet mechanism, the amount of movement of the device body is determined by the dimensions of the ratchet groove and ratchet claw, so it is difficult to accurately match the mounting height of the device body with the ceiling panel using only the ratchet mechanism. There is a possibility that a gap is opened between the flange portion and the ceiling panel, and the airtightness cannot be secured.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a facility device and a facility device construction method that can ensure airtightness and can be easily constructed.

  In order to solve the above-described problems, the present invention includes a mounting frame that is suspended from the ceiling of a building, and a device main body that is attached to the mounting frame, and the mounting frame protrudes outward from the lower side of the side surface of the device main body. And a side surface portion of the mounting frame between the side surface portion of the mounting frame and the opening edge of the opening portion. And a sealing member in contact with the opening edge of the opening.

  Further, according to the present invention, the mounting frame is suspended from the ceiling of the building, and the sealing member provided on either or both of the side surface of the mounting frame and the opening edge of the opening formed on the ceiling is pressed. As described above, the installation method of the equipment is such that after the ceiling member that forms the opening in the ceiling is installed facing the side surface of the mounting frame, the apparatus main body is mounted on the mounting frame.

  In the equipment of the present invention, even when a gap is formed between the flange portion of the apparatus main body and the ceiling surface, the state where the sealing member is pressed against the opening edge of the opening is maintained, and the mounting frame, Airtightness is ensured between the opening edge of the opening.

  Further, in the construction method of the equipment of the present invention, the installation of the mounting frame on the ceiling is performed in a state where the apparatus main body is not mounted on the mounting frame, and the mounting frame does not match the predetermined mounting height, The mounting height is adjusted in a state in which the apparatus main body is not mounted on the mounting frame.

  According to the present invention, even if an error occurs in the mounting position of the apparatus main body at the opening of the ceiling where the apparatus main body is installed, the space between the indoor side and the ceiling side can be sealed to maintain airtightness. it can. Moreover, in the state which has not attached the heavy apparatus main body to the attachment frame, installation of an attachment frame and adjustment of attachment height can be performed, and it becomes possible to perform construction easily.
